Ransomware continues to be one of the most formidable cyber threats facing businesses and institutions around the world. With attacks increasing in both volume and sophistication, cybersecurity companies are under pressure to deliver solutions that not only detect and prevent attacks but also instill confidence among users. One company that has taken a bold step in this direction is SentinelOne, a vendor of endpoint security solutions. Their unique proposition, a financial guarantee backing their ransomware protection technology, sets them apart in a highly competitive market.
This initiative is centered around a cyber-threat protection guarantee, which provides users with financial reimbursement in the event of a ransomware attack that the SentinelOne platform fails to block or remediate. Specifically, the program offers compensation of $1000 per endpoint affected, up to a total of $1 million per organization. This approach represents a significant shift in how cybersecurity vendors engage with customers, shifting from simply providing tools and services to actively sharing in the risk and consequences of failure.
A New Standard in Accountability
The guarantee applies only to customers who have opted into the program and are using SentinelOne’s Endpoint Protection Platform (EPP) or Critical Server Protection Platform (CSPP). This opt-in requirement ensures that only users who are fully utilizing the platform’s features and adhering to its best practices are eligible for the financial backing. It also reflects a level of accountability from the customer side, demanding that certain configurations and policies be followed to maintain eligibility.
Tomer Weingarten, co-founder and CEO of SentinelOne, emphasized the company’s commitment to tackling ransomware directly. At a roundtable event in London, Weingarten discussed the importance of providing not just technical protection but also the assurance that comes with financial coverage. He highlighted the rigorous criteria for claim eligibility, including the need for forensic evidence and real-time validation that an external attack took place and not an internal manipulation.
Bridging the Gap Between Security and Business Risk
For ransomware writers, indiscriminate targeting is the norm. Attackers do not typically care who they infect, as long as the ransom is paid. SentinelOne’s value proposition is to become a reliable partner in these scenarios by offering customers a layer of comfort in knowing they are protected, and if protection fails, that they are financially covered. According to the company, users who follow the program’s requirements and are still affected by a ransomware incident can expect coverage for the ransom cost. This eliminates the pressure to negotiate with criminals or absorb costly operational setbacks.
The SentinelOne Cyber Guarantee is positioned as an opt-in program specifically designed to cover damages caused by ransomware attacks that were not detected or mitigated by SentinelOne’s EPP or CSPP platforms. It provides financial relief in cases where the technology does not perform as expected, thereby reinforcing customer trust and satisfaction. This is not merely a form of cyber insurance; SentinelOne is clear in communicating that their guarantee is meant to cover only the ransom itself, not broader damages like intellectual property loss or reputational harm.
Technical Considerations and Real-World Implications
When a ransomware attack is detected, SentinelOne’s technology is capable of mitigating the threat automatically. It can remediate the attack by rolling back files to their pre-infection state, provided certain technical conditions are met. This rollback functionality requires that Shadow Copy is enabled on Windows-based systems and that the SentinelOne agent is installed on every endpoint or server involved. Additionally, the management console must have “Cloud Validation” turned off, and the mitigation policy must be set to “Quarantine” to ensure eligibility for the guarantee.
SentinelOne’s plan includes a rollout to approximately 500 enterprises, balancing risk management with customer demand. Weingarten acknowledged that while the company does not claim to be infallible, it is ready to stand by its product measurably. The company understands that some claims will be paid, but views this as a cost worth bearing to elevate the standard of trust in the cybersecurity industry.
Weingarten also emphasized the value proposition in comparison to traditional antivirus vendors. He pointed out that customers often pay for antivirus subscriptions that offer no compensation when breaches occur, and in turn, must spend even more to resolve ransomware infections. By contrast, SentinelOne offers a bundled approach that includes a minimal premium and a significant potential payout if protection fails.
This sentiment was echoed by others present at the roundtable. Graeme Newman of CDC Underwriting noted that the financial guarantee demonstrates an extraordinary level of confidence in the product. Former hacker and security consultant Robert Schifreen also highlighted that this offer goes beyond symbolic assurance, giving customers a tangible fallback if protection mechanisms fail.
Limitations and Outlook
One critical caveat in the program is the requirement for up-to-date systems. If a ransomware attack exploits vulnerabilities in outdated software, and the customer cannot prove that the exploited system was fully updated, the claim may be denied. This underscores the necessity of maintaining proper cyber hygiene to benefit from the financial guarantee.
While SentinelOne is setting a new precedent, questions remain about the accessibility of the guarantee. The detailed technical prerequisites and forensic verification requirements may make it challenging for some organizations to successfully file claims. Nevertheless, the company distinguishes its offering from traditional insurance by emphasizing that its purpose is to protect the customer rather than shield the vendor from liability.
This program could spark a larger shift in the industry. If successful, it may lead to more cybersecurity vendors incorporating financial guarantees into their offerings. In doing so, the industry could move toward more meaningful customer protection models, transforming cybersecurity from a technical utility into a trusted business service.
The move by SentinelOne also reignites discussions around the effectiveness of current cybersecurity strategies. If standard practices like backups and endpoint protection are not enough to prevent ransomware attacks, then perhaps the model needs rethinking. SentinelOne’s financial guarantee is not just a vote of confidence in their technology—it is a challenge to the industry to offer more than just tools, but also tangible accountability.
No other cybersecurity company currently offers a similar financial commitment. In doing so, SentinelOne is not only acknowledging the limitations of current technology but also actively addressing them. It represents a significant step forward in aligning technology with business continuity and may well serve as a blueprint for the future of cybersecurity solutions.
Understanding the Mechanics of SentinelOne’s Guarantee
SentinelOne’s ransomware protection guarantee is a proactive step toward bridging the trust gap between cybersecurity vendors and enterprise clients. Unlike typical vendor promises focused solely on prevention capabilities, this guarantee places financial backing behind those claims. The mechanics of this guarantee, while straightforward in principle, are defined by specific eligibility conditions, technical requirements, and operational policies.
At the core of this program is a clearly outlined reimbursement model. If SentinelOne fails to prevent or adequately remediate a ransomware attack on an enrolled client’s systems, the company will pay the customer $1,000 per endpoint affected, up to a total of $1 million per organization. This payout is designed to cover the direct costs associated with ransom demands. SentinelOne is very clear, however, that this guarantee does not function as traditional cyber insurance. It does not cover loss of revenue, reputation damage, or costs related to regulatory issues or intellectual property loss.
To qualify for the guarantee, customers must opt into the program and meet several technical conditions. This includes the installation and active running of SentinelOne’s Endpoint Protection Platform (EPP) or Critical Server Protection Platform (CSPP). All protected endpoints must be running the SentinelOne agent, and specific policies must be enforced within the SentinelOne management console. These include disabling ‘Cloud Validation’ and enabling the ‘Quarantine’ mitigation policy.
Prerequisites for Enrollment and Technical Compliance
Opting into the SentinelOne Cyber Guarantee is not automatic. Clients must voluntarily enroll in the program, which ensures that both the company and the customer understand and accept the responsibilities tied to the agreement. This process serves as a filter to limit the guarantee to customers who are committed to maintaining a secure and properly configured environment.
The guarantee stipulates that only organizations with properly deployed and managed environments are eligible for compensation. Each endpoint must have the SentinelOne agent actively running. Any systems without the agent or running improperly configured software are disqualified from the guarantee. For Windows-based systems, another crucial technical requirement is the enabling of Shadow Copy. This is because SentinelOne’s rollback functionality, which restores files to their pre-infection state, depends on it.
Equally important is ensuring that the SentinelOne management console settings comply with guarantee conditions. ‘Cloud Validation’ must be turned off, which ensures endpoint-level decision making, and the response policy must be set to ‘Quarantine,’ which isolates suspicious activity instantly. These configurations help ensure that SentinelOne’s real-time protection capabilities are active and functioning as designed.
If an attack occurs while these configurations are not met, even if the ransomware manages to bypass protection, the guarantee may not be honored. This highlights the shared responsibility between SentinelOne and its customers. While the company offers compensation, it also places the onus on the organization to operate within clearly defined technical boundaries.
Forensic Evidence and Claim Validation
A cornerstone of the guarantee’s integrity is its reliance on forensic evidence. SentinelOne must be able to validate that the ransomware attack was genuine, that it bypassed their protection, and that it wasn’t a result of negligence or misuse by the client. This means that once an incident is reported, SentinelOne’s security team launches a detailed investigation.
This forensic analysis looks for evidence of the ransomware variant involved, the timeline of infection, the presence of the SentinelOne agent, and whether the affected systems were compliant with all required configurations. The claim process is transparent, but stringent. SentinelOne reserves the right to deny claims where it finds that customer-side misconfigurations or outdated software were responsible for the breach.
For instance, if an organization fails to apply critical updates or continues to run unsupported operating systems, SentinelOne may reject the claim. As noted by Tomer Weingarten, companies are expected to be using the most recent software updates and patches. SentinelOne’s rationale is that no technology, however robust, can protect systems that are inherently vulnerable due to negligence.
In effect, the guarantee demands not just the presence of the SentinelOne product, but also best practices in cybersecurity operations. This pushes organizations to maintain a higher standard of digital hygiene, aligning well with the broader goals of resilience and accountability in cyber defense.
Not a Cyber Insurance Policy
A key distinction SentinelOne makes is that this program is not cyber insurance. It is not designed to replace traditional insurance policies, nor is it intended to shield SentinelOne from legal claims. Instead, it is positioned as a customer-first initiative that reflects confidence in the product’s ability to prevent ransomware infections. SentinelOne emphasizes that the guarantee is about accountability rather than liability protection.
This philosophical distinction is important. Insurance is primarily a financial product designed to protect the insured entity (or sometimes the vendor) from the fallout of a cyber incident. These policies often come with exclusions, delays, or complications that can limit their usefulness in real-time crisis management. SentinelOne’s guarantee, by contrast, is focused on immediate, measurable reimbursement for failures specifically tied to ransomware prevention.
By offering a direct payout model rather than relying on third-party insurers, SentinelOne bypasses the bureaucracy that often surrounds claims processing. This helps build trust and transparency, allowing customers to rely on a straightforward compensation framework in the event of a verified failure. It also establishes SentinelOne’s commitment to standing behind the performance of its platform in a concrete way.
Another advantage is cost predictability. Organizations pay a fixed premium per endpoint—approximately five dollars, according to SentinelOne executives—to participate in the guarantee. This removes the ambiguity often associated with insurance coverage, where premiums may vary widely based on company size, industry, history of incidents, and other risk factors.
Business Justification and Market Positioning
From a business perspective, the guarantee strengthens SentinelOne’s value proposition. It moves beyond the crowded landscape of endpoint detection claims and toward a differentiated offering based on outcome-based security. In doing so, it challenges competitors who continue to sell licenses with little or no financial accountability tied to performance.
This strategy also opens the door for deeper customer relationships. Enterprises that sign up for the guarantee are likely to engage more closely with SentinelOne’s deployment and security teams, ensuring tighter integrations, higher compliance with best practices, and potentially greater product satisfaction.
The guarantee serves a dual purpose: providing peace of mind to existing customers and acting as a compelling sales tool for new prospects. It’s a bold statement in a market filled with technical jargon and feature parity. When many security vendors make similar claims about detection rates or AI-based protection, putting money on the line sends a much clearer message.
That said, SentinelOne is also realistic about the risks. The company acknowledges that some payouts will occur. By accepting these costs, it is signaling long-term confidence in its platform’s effectiveness and maturity. It’s a gamble—but one that also aligns with the broader industry movement toward transparency, performance accountability, and shared risk.
Shared Risk and Customer Responsibility
One of the most pivotal aspects of SentinelOne’s ransomware guarantee is the concept of shared responsibility between the vendor and the customer. While the company is making a bold commitment to stand behind its technology with a financial guarantee, it also places a corresponding obligation on the customer to maintain a baseline of cybersecurity hygiene and infrastructure readiness. This mutual accountability forms the bedrock of the guarantee and reflects a mature approach to cybersecurity risk management.
Cybersecurity has traditionally been framed as a vendor-customer dynamic where the provider delivers the tools, and the client implements them to the best of their ability. However, this model often leads to unclear accountability when failures occur. SentinelOne disrupts this paradigm by tying the efficacy of its protection directly to customer adherence to certain configuration standards and operational practices. This effectively creates a two-way contract: SentinelOne promises to pay if its technology fails, but only if the customer has upheld their part of the bargain.
To qualify for the ransomware protection guarantee, customers must meet specific requirements related to the deployment and configuration of the SentinelOne platform. These include enabling the Shadow Copy feature on Windows-based endpoints and servers, installing SentinelOne agents on all relevant devices, and ensuring that key policy settings like mitigation mode and cloud validation are properly configured. Failure to adhere to these prerequisites could render a claim ineligible, highlighting the importance of precision and diligence in system management.
This model promotes a higher standard of operational excellence within organizations. IT and security teams must take the time to properly understand the configuration requirements and ensure that endpoints are correctly set up and maintained over time. In doing so, they not only remain eligible for the guarantee but also benefit from improved protection due to optimal product performance.
SentinelOne’s approach encourages organizations to think beyond simply deploying a tool and assuming they are safe. Instead, it requires continuous monitoring, management, and alignment with best practices. This fosters a deeper engagement with cybersecurity tools and promotes a culture of shared vigilance.
The company’s CEO, Tomer Weingarten, emphasized that the guarantee is not meant to be an insurance policy in the traditional sense. Insurance, in most cases, is designed to protect the provider from liability while compensating the customer. In contrast, SentinelOne’s model is based on performance and accountability. The company is not offering coverage for damages related to intellectual property loss, business disruption, or legal fallout. The guarantee is strictly focused on ransom-related losses when its product fails to block or mitigate an attack.
This distinction underscores the need for businesses to view cybersecurity as a layered, multifaceted strategy. While SentinelOne can offer a strong line of defense and even reimbursements in some failure cases, it cannot serve as a total solution for all cyber risks. Businesses must still invest in other critical areas such as employee training, data backups, incident response plans, and regulatory compliance. The SentinelOne guarantee is an added layer of assurance, not a replacement for a robust security ecosystem.
Moreover, the requirement for up-to-date software and systems illustrates a broader principle in cybersecurity: the weakest link often determines the overall security posture. If an organization is running outdated operating systems or has endpoints that lack critical patches, the effectiveness of any security platform, including SentinelOne, can be severely compromised. By conditioning eligibility on factors such as system updates and policy configurations, SentinelOne reinforces the importance of maintaining a strong foundational infrastructure.
The shared responsibility model also benefits the cybersecurity industry as a whole. It sets a precedent for clear expectations between vendors and clients. Rather than hiding behind ambiguous service agreements or technical disclaimers, both parties are now incentivized to maintain transparency, documentation, and consistent communication. This openness is crucial in a field where trust is paramount and reputational damage can be just as costly as financial loss.
In practice, SentinelOne’s shared responsibility model may even lead to operational changes within customer organizations. Security teams may introduce stricter endpoint compliance checks, deploy automated validation tools to ensure configuration integrity, or establish regular audits to verify that all agents are active and functioning correctly. These practices not only help maintain eligibility for the guarantee but also strengthen the overall security framework.
Another dimension of shared responsibility involves the role of managed service providers (MSPs) and third-party IT partners. Many organizations rely on external vendors to manage or supplement their cybersecurity efforts. In these scenarios, all stakeholders must understand the terms and technical requirements of the SentinelOne guarantee. Miscommunications or oversights at the service provider level could inadvertently disqualify a customer from receiving compensation. This places a premium on vendor coordination and collaborative governance.
For SentinelOne, this model of shared risk is a powerful statement of belief in their technology. It’s not just about marketing confidence—it’s a financial bet that their detection and mitigation capabilities are strong enough to prevent the majority of ransomware threats. At the same time, they are signaling that protection cannot be a passive process. It must be actively managed and nurtured by customers who are equally invested in their cyber resilience.
By aligning the interests of both parties, SentinelOne is fostering a more honest, practical, and performance-oriented relationship with its users. The guarantee model helps move the industry away from one-size-fits-all solutions and toward tailored, strategic partnerships where both sides contribute to the outcome. This evolution may ultimately lead to a healthier, more resilient cybersecurity landscape where tools and processes are held to higher standards—and where accountability is built into the core of every deployment.
Industry Reactions and Competitive Landscape
SentinelOne’s ransomware guarantee has generated significant discussion within the cybersecurity industry. By stepping beyond the typical promises of prevention and detection, the company has invited both admiration and scrutiny from analysts, competitors, and enterprise security leaders. While many acknowledge the boldness of the initiative, there is also a sense of curiosity about how this financial backing will play out at scale and whether it will force a shift in industry standards.
The guarantee has been described by experts as a major vote of confidence in SentinelOne’s technology. Graeme Newman, CIO of CDC Underwriting, emphasized that few companies are willing to put their financial reputation on the line in this way. The guarantee is not symbolic—it represents a contractual commitment to reimburse customers if the technology fails. This is particularly compelling when compared to traditional antivirus or endpoint detection and response (EDR) products, which often disclaim liability in cases of breach.
For competitors, SentinelOne’s move places pressure on them to justify their levels of confidence. If one vendor is willing to offer compensation for failure, the question arises: why aren’t others doing the same? This creates a new lens through which customers evaluate cybersecurity products—not just by features or benchmarks, but by how much the vendor is willing to stake on its promises.
That said, most vendors are hesitant to follow suit. Financial guarantees carry inherent risk, particularly in a threat landscape where attackers are constantly innovating. There’s also concern about abuse or misinterpretation of terms. As such, SentinelOne’s competitors are likely to watch closely before launching similar initiatives, waiting to see how sustainable and successful this model proves to be in real-world deployments.
Comparison to Traditional Cyber Insurance
One of the most important distinctions SentinelOne draws is between its guarantee and cyber insurance. The guarantee is not meant to be a substitute for an insurance policy. Instead, it is a targeted solution aimed at a specific threat: ransomware. While insurance is designed to cover a broader range of risks, from data breaches to regulatory fines and operational downtime, SentinelOne’s guarantee is focused purely on the cost of the ransom itself.
This approach simplifies the process for customers. Cyber insurance policies are often filled with exclusions, long claim processes, and unpredictable reimbursements. By contrast, SentinelOne’s program outlines a clear payout structure—$1,000 per endpoint, up to $1 million per organization—making it easier for clients to understand their potential coverage. The claim process, while still requiring forensic validation, is more transparent and less bureaucratic than traditional insurance channels.
Another key advantage is response time. Insurance claims can take weeks or months to resolve, often requiring extensive documentation and multiple layers of approval. SentinelOne’s guarantee offers more immediate relief, helping organizations recover faster and with fewer obstacles. This is particularly valuable during a ransomware crisis, when quick access to funds can mean the difference between continuity and collapse.
However, there are also limitations. The guarantee does not cover damages related to data loss, intellectual property theft, or long-term reputational harm. Nor does it protect against fines from data protection regulators or contractual penalties. These are areas where cyber insurance still plays a crucial role. For businesses with broader risk exposure, combining SentinelOne’s guarantee with a comprehensive insurance policy may offer the most complete protection.
Ultimately, the two offerings serve different needs. SentinelOne’s guarantee is product-driven and specific. Insurance is policy-driven and general. Organizations need to understand both tools and use them accordingly. What SentinelOne has done, however, is raise the bar by embedding financial accountability directly into its product offering—a move that few, if any, vendors have matched.
Enterprise Adoption and Scalability
SentinelOne has initially capped its guarantee at approximately 500 enterprises. This limited rollout allows the company to monitor the program’s effectiveness, gather performance data, and refine the terms as needed. It also helps manage financial risk, particularly in the early stages when real-world claims and scenarios are still being understood.
Early adopters are likely to include mid-size to large enterprises with mature IT environments and a proactive approach to cybersecurity. These organizations are more likely to meet the technical requirements, including full agent deployment, policy configuration, and compliance with update schedules. They also tend to have the in-house expertise needed to respond quickly to ransomware attacks and to collect the forensic evidence needed for claim validation.
Smaller businesses may face more challenges in adopting the guarantee. Many lack the resources or personnel to ensure full compliance with technical prerequisites. For these organizations, managed security service providers (MSSPs) or value-added resellers (VARs) may play a critical role in helping configure and maintain eligibility for the guarantee. SentinelOne could expand its reach by developing partnerships or offering turnkey services to support these customers more directly.
Over time, if the program proves successful, SentinelOne may lift the cap and expand availability. This would likely require a more automated claims process, better integration with threat intelligence platforms, and continued education for customers on how to maintain compliance. SentinelOne may also refine or tier its offerings, introducing varying levels of coverage or add-ons for broader threat scenarios.
Potential Pitfalls and Skepticism
While the concept of a ransomware guarantee is attractive, it is not without risks. One concern is that the terms may be so strict that few customers ever qualify for a payout. If the forensic validation process is overly complex or if technical prerequisites are frequently missed, customers may grow frustrated or cynical. This could lead to the perception that the guarantee is more marketing than substance.
To counter this, SentinelOne will need to be transparent about its claims process and possibly publish statistics on accepted and rejected claims. It will also need to offer support services that help clients maintain compliance and understand eligibility criteria. Trust is built not just on the offer itself, but on how that offer is honored.
Another potential issue is the evolving nature of ransomware itself. Attackers are adapting quickly, and new variants may use techniques that bypass current detection methods. SentinelOne will need to continuously update its platform to stay ahead of these threats. If the product falls behind the curve, the guarantee could become financially unsustainable or ineffective in building trust.
There’s also the broader industry question of whether guarantees like this should be standard. If only one or two vendors offer financial backing, it may become a niche feature rather than a new norm. On the other hand, if more vendors follow SentinelOne’s lead, the industry may shift toward greater accountability and customer-centric protection models.
Finally, some critics may argue that a guarantee could create a false sense of security. Companies might believe they are fully protected just because a payout is promised. This could lead to lax security practices or overreliance on technology. SentinelOne must therefore reinforce that the guarantee is not a replacement for good cybersecurity hygiene—it is a fallback mechanism, not a shield against every possible consequence.
Building a Culture of Cyber Accountability
Despite these challenges, SentinelOne’s ransomware guarantee is a clear step toward a culture of accountability in cybersecurity. It represents a willingness to stand behind the product, not just with words, but with financial consequences. This sends a powerful signal to customers and competitors alike: trust must be earned, and performance must be measurable.
The cybersecurity industry has often operated on a model of caveat emptor—let the buyer beware. Vendors promise high detection rates, AI-based intelligence, and seamless remediation, but rarely do they offer recourse when those claims fall short. SentinelOne is breaking that mold by saying, in effect, “If our product doesn’t work, you won’t be left holding the bag.”
This approach may help shift the dialogue from features and capabilities to outcomes and reliability. It could also inspire new models of partnership between vendors and clients, where risk is shared and success is measured by real-world results rather than abstract metrics.
Final Thoughts
SentinelOne’s ransomware protection guarantee marks a bold, disruptive step in the cybersecurity industry—one that signals a broader shift toward accountability, transparency, and performance-based value. By offering direct financial compensation if its technology fails to stop a ransomware attack, the company has moved beyond promises and into verifiable commitments. This is not just a product feature—it’s a statement of confidence and a challenge to the rest of the industry.
For organizations, this model offers a rare sense of security in a threat landscape defined by uncertainty. Ransomware has grown more sophisticated, more frequent, and more damaging over time. Yet despite billions spent globally on cybersecurity tools, many companies are still left vulnerable. SentinelOne’s guarantee addresses a core fear head-on—not only by attempting to block ransomware but by ensuring there’s a fallback if things go wrong.
But this isn’t a silver bullet. The guarantee has conditions, and organizations must uphold their end by maintaining the required configuration, deploying the right tools, and keeping systems updated. It promotes shared responsibility, and that’s a healthy evolution for both customers and vendors. It also exposes SentinelOne to real financial risk, meaning the company is betting heavily on its engineering, detection capabilities, and rapid response features.
The broader implication is a new standard: cybersecurity vendors should no longer hide behind disclaimers when their tools fail. SentinelOne has raised the bar, and even if other companies don’t offer the same kind of guarantee, they will likely need to find ways to demonstrate similar levels of trustworthiness and effectiveness. Outcome-driven protection could become the new norm.
In the end, this initiative isn’t just about recovering from ransomware. It’s about rebuilding trust in the cybersecurity space. Businesses need to know that the tools they invest in will work, not just in lab tests or vendor demos, but in the real-world chaos of modern cyberattacks. SentinelOne’s move won’t end ransomware, but it brings us one step closer to a world where security solutions are accountable, dependable, and truly worth the price we pay.
