While cyber insurance is a regulated policy covering a broad range of breach losses, a cyber warranty is a vendor contract paying fixed amounts on defined triggers. Since both can provide financial support after a cyber incident, buyers may confuse their roles. That misunderstanding can lead to gaps in financial protection or unrealistic expectations during a claim.
Cyber insurance and cyber warranties generally serve different, complementary purposes. They operate at different layers: cyber insurance is designed to cover insured losses under a policy, while a cyber warranty helps offset specific costs when defined security and payout conditions are met.
This article explains how cyber warranties work, how they differ from cyber insurance, what each typically covers, and how the two can work together when a covered incident occurs.
Key points of this article:
- A cyber warranty isn’t insurance and doesn’t replace it. It is a contract with your security vendor, not a regulated policy.
- Cyber warranties typically help cover costs that your business may still have to pay after a cyber incident, such as insurance deductibles, waiting periods, and other eligible out-of-pocket expenses.
- Coverage depends on maintained controls. The control list, not the headline limit, determines whether a claim pays.
- Insurance is portable and renewable; a warranty ends with the subscription and can be withdrawn by the vendor.
- Both instruments now require broadly the same controls, so the security work can help you qualify for both.
What’s the difference between a cyber warranty and cyber insurance?
Cyber insurance is a regulated policy that transfers a broad range of breach losses to an insurer, with each claim assessed individually. A cyber warranty is an unregulated contract from a security vendor that pays fixed amounts on defined triggers, and only if required controls were maintained. We explain cyber warranties in detail in our article, “What is a cyber warranty and why are security vendors offering them?”
The two mechanisms are complementary and can be used together for layered cyber resilience:
- A cyber warranty is a contract that ties benefits to a specific security offering and required controls. As a vendor’s expression of confidence in its controls, it functions like a performance guarantee, but applies only to certain qualifying incidents.
- A cyber insurance policy is designed to cover financial losses after a cyber incident. It applies to a much wider range of conditions than a cyber warranty. Each policy defines specific coverage, deductibles, exclusions, limits, and premiums. The insurer reviews, adjusts, and pays on claims based on a formal process.
Used together, a cyber warranty and cyber insurance may address different parts of an organization’s financial exposure. This helps reduce potential coverage and cash flow gaps during recovery. Maintaining the required controls improves cybersecurity, business continuity, and stakeholder confidence.
The table below compares cyber warranty coverage with a cyber insurance policy.
| Dimension | Cyber insurance | Cyber warranty |
|---|---|---|
| What it is | A regulated insurance policy (i.e., sold by a licensed insurance company). | A commercial contract with your security vendor. |
| Who stands behind it | A licensed carrier, under state insurance regulation. | The vendor or its warranty provider, on contract terms alone. |
| Regulated? | Yes. Licensing, financial oversight to help ensure claims can be paid, market conduct rules. | No. No regulator, no guaranty fund, no special legal protections available under insurance law. |
| What triggers payment | A covered loss, as defined by the policy. | A defined event, if required controls were maintained. |
| How the amount is decided | Determined claim by claim based on the covered loss. | Predetermined amounts tied to specific covered event types. |
| What it covers | A broad range of cyber-related financial losses, subject to policy terms. | Specific incidents and expenses defined by the warranty. |
| Underwriting | Priced and evaluated based on your organization’s risk profile. | Fixed program terms; eligibility by product tier. |
| Cost | A premium, plus a deductible (sometimes called a retention) you carry yourself. | Usually bundled with the security subscription. |
| Claims per term | Multiple, up to the policy limit. | Commonly one qualifying event in a 12-month period. |
| Which pays first | Follows a formal claims process and may take weeks or months to resolve. | Can resolve quickly when no insurance policy is involved. If insurance responds, the warranty follows the policy timeline. |
| Primary financial role | Absorbs the loss above your deductible. | Covers the deductible, the waiting period, and out-of-pocket costs. |
| If you change vendors | Portable; the policy is yours. | Ends with the subscription. |
| Durability | Renewable; carriers are regulated for solvency. | Withdrawable; programs have been discontinued before. |
Does a cyber warranty replace cyber insurance?
A cyber warranty doesn’t replace cyber insurance. A cyber warranty pays fixed amounts on a short list of defined events and is typically excess to other benefits a business already holds, while cyber insurance covers a far broader range of first-party and third-party losses (losses to your own business and losses involving customers, partners, or other third parties).
Can you have a cyber warranty and cyber insurance?
Cyber warranties are generally designed to work alongside cyber insurance, not replace it. For that reason, warranty providers often require organizations to use any available insurance coverage or other benefits first. The warranty then helps cover eligible costs that remain, such as deductibles, waiting periods, or other out-of-pocket expenses.
Why businesses use both
Cyber warranties can also help lower your cyber insurance premium. The security controls that the warranty requires help reduce the likelihood and impact of an incident, while the warranty may cover some of the costs that would otherwise fall to the insurer. With less risk to absorb, the insurer may be able to offer more favorable pricing.
Some cyber incidents result in eligible losses below the policy deductible, leaving the business responsible for those costs. A cyber warranty may provide value if its terms reimburse applicable expenses. That's where a cyber warranty can provide value by covering certain qualifying expenses. Cyber insurance acts as the broader safety net for larger losses and risks that the warranty doesn’t cover.
Which pays first, a cyber warranty or cyber insurance?
A cyber warranty most often pays into the gaps a cyber insurance policy deliberately leaves with the insured: the deductible, and the waiting period before business interruption coverage begins. The insurance industry calls this function deductible buy-back.
Which pays first depends on whether the incident triggers an insurance policy. Many don’t, because the mandated controls contained the event. In that case, the only reimbursement (if any) comes from the warranty.
Here’s what that would look like in the case of a ransomware attack in two scenarios:
The incident doesn’t trigger cyber insurance coverage:
- The organization detects a ransomware attack and notifies the warranty provider within the required notification period (typically 48 hours after discovery).
- The warranty provider verifies that the required security controls were maintained and that the incident meets the warranty’s payout conditions.
- The warranty provider determines whether the claim qualifies under the warranty terms.
- If approved, the warranty provider reimburses eligible expenses.
The incident triggers cyber insurance coverage:
- The organization detects a ransomware attack and notifies both the cyber insurance carrier and warranty provider within the required notification period.
- The insurance carrier investigates the incident and determines what losses are covered under the policy.
- The insurer pays covered losses above the policy deductible and any applicable waiting period.
- The warranty provider reviews the claim and reimburses eligible expenses, such as the deductible, waiting-period costs, or other qualifying out-of-pocket expenses.
When an incident triggers a cyber insurance policy, the carrier takes the lead on investigation and remediation. The warranty provider works in coordination with the carrier to cover impacts like the deductible, costs falling outside the policy’s waiting period, and costs that overrun the policy limits.
For incidents that aren’t eligible for cyber insurance, cyber warranty claims typically move more quickly than insurance claims because they only look at whether the incident met payout trigger conditions. Cyber insurers need to calculate the size of the covered loss, a more complex process.
“We always recommend formally notifying the cyber insurance carrier, even if you don’t intend to have them respond immediately,” says Kirsten Bay, co-founder and CEO of Cysurance, the independent provider of ESET’s cyber warranty. “Filing preserves the right to bring the claim later, and that right is easy to lose while waiting to see how an incident develops.”
What a cyber warranty won’t cover
A cyber warranty doesn’t cover business email compromise involving a social-engineered funds transfer where no network compromise occurred, the full breadth of third-party liability an insurance policy carries, or incidents in parts of the environment the vendor doesn’t protect.
A ransomware payment may still be made when necessary, but it requires prior approval and a compliance review to ensure the payment doesn’t violate U.S. sanctions laws or other legal restrictions.
Common cyber warranty exclusions
The exclusion list is an area where cyber warranties vary the most between vendors, so it is important to review contract language carefully. Because they are intended to close coverage gaps when a specific cybersecurity solution fails, the exclusions can be very different based on the functionality the warranty stands behind.
Why some BEC incidents are excluded
The rationale behind many cyber warranty exclusions is the question of whether an attack defeated a fully functional security control.
For example, a common cyber warranty exclusion is a business email compromise (BEC) incident where social engineering results in a funds transfer without a network compromise. When an employee is deceived into authorizing a payment, that is a business process failure, not a control failure.
Conversely, a cyber warranty may explicitly cover a BEC incident where a user’s mailbox or identity was hacked, as ESET’s does because this constitutes a security control failure, which is exactly what the warranty mitigates.
“If the attack didn’t overcome a warranted security control, there is nothing for the control vendor’s warranty to respond to,” says Kirsten Bay. “The distinction is that a network compromise must have occurred to receive a payout.”
The controls you have to maintain for a warranty to pay
Cyber insurance underwriters and cyber warranty providers now require substantially the same security controls, so implementing these controls may help a business meet requirements commonly assessed by both cyber insurers and warranty providers.
Multi-factor authentication, managed detection and response, immutable (tamper-resistant) backups and a documented patch cadence appear on both lists.
The following checklist covers nine core security controls that illustrate many cyber warranty providers’ control requirements:
| Control area | Details |
|---|---|
| Endpoint protection | All endpoints must be protected by actively managed security software. |
| MDR/SIEM | A managed detection and response (MDR) service or security information and event management (SIEM) capability must actively monitor the applicable environment. |
| Multi-factor authentication | MFA must be enforced for all email accounts, privileged/administrative accounts, and other high-risk access points. |
| Backups | Backups must be regularly tested to validate they are protected from ransomware attacks. |
| Encryption | AES-256 encryption, an industry-standard data protection method, must protect all data. |
| Maintenance | Applicable patches for known vulnerabilities must be installed within 60 days of the vendor’s release date. |
| Compliance | Participants must comply with all applicable privacy, security, and regulatory requirements, including PCI DSS, HIPAA, GDPR, or other relevant frameworks. |
| Security awareness | The organization must document regular security awareness training completed by applicable employees and contractors. |
| Business controls | Participants must put controls in place to prevent unauthorized financial transactions and wire fraud. |
Do I need both cyber insurance and a cyber warranty?
Most organizations that carry a cyber warranty still need cyber insurance. A cyber warranty covers a defined slice of incident cost; a cyber insurance policy covers the loss itself, is individually underwritten, and is backed by a licensed carrier.
Without cyber insurance to transfer the excess risk, severe cyber incident impacts could lead to significant legal, regulatory, and third-party liabilities on top of major financial damage. A cyber warranty would only cover part of these costs at most.
Without a cyber warranty, an organization forfeits the possibility of financial support for specific incidents related to the warranty vendor’s technology. Lack of a warranty also nullifies the potential benefit of lower cyber insurance costs through implementing the required controls.
Here are coverage recommendations for the most common scenarios:
| Scenario | Recommendation |
|---|---|
| You have cyber insurance and can obtain a cyber warranty bundled with your chosen MDR or cybersecurity solution. | Take it. A cyber warranty isn’t a replacement for cyber insurance, but it can help cover some of the costs that fall back on your business after a cyber incident. |
| You have no cyber insurance and are considering a cyber warranty as a substitute. | Don’t treat a cyber warranty as an equivalent substitute. A warranty serves a different purpose and covers a much narrower set of incident impacts. |
| Your organization cannot obtain suitable cyber insurance within its budget. | If you are considering a security offering that includes a cyber warranty, there is no reason not to accept its promise of financial support within the stated limits. |
How to read a warranty before you rely on it
Reading a cyber warranty before relying on it means establishing whether it pays primary or excess to benefits the business already holds. Other terms and conditions that affect a cyber warranty’s value to your business include:
- Is the limit per participant or per endpoint?
- What is the realistic maximum payout for your business?
- What specific cybersecurity controls must your business maintain?
- What exclusions could void a claim?
- How does the cyber warranty provider evaluate your cybersecurity posture?
- How many claims per term can a business make?
- What is the notice window?
- Do the benefits apply to a range of incidents, or just a few?
- Is the warranty only available with the most expensive solution tier?
- Does a licensed insurance carrier back the warranty?
- Are the full warranty terms published online?
How ESET’s cyber warranty works alongside insurance
ESET’s cyber warranty is designed to be used alongside cyber insurance rather than instead of it. Incidents should be reported to both the warranty provider and the insurance carrier, and the warranty may cover insurance deductibles, waiting periods or other out-of-pocket costs.
ESET’s warranty supports end-to-end risk protection by filling the gap between a customer’s certified cybersecurity program and its insurance policy. ESET’s cyber warranty is available with specified eligible ESET subscriptions for customers in the United States and Canada. Availability, benefit level, activation, and required controls depend on the subscription and applicable program terms.
Under ESET’s cyber warranty terms, all other financial benefits must be exhausted before the cyber legal liability indemnification level (i.e., coverage amount) is triggered. This includes cyber insurance payouts.
ESET’s cyber warranty is provided and administered by Cysurance, an independent third party. For complete eligibility requirements, coverage conditions, and claim procedures, review the ESET Cyber Warranty program details.
Benefits of an ESET cyber warranty for companies with cyber insurance include:
- Financial support: Approved claims are funded within 72 hours of approval, with remediation support available where needed alongside your security vendor or MSP. (Keep in mind that where a cyber insurance policy is also responding, approval follows the policy timeline.)
- Lower premiums: Support for more favorable cyber insurance pricing by validating robust cybersecurity practices that help contain incidents and reduce cyber risk.
- Streamlined payouts: A simpler path to reimbursement for smaller incidents. For qualifying incidents that may not trigger a cyber insurance payout, funding is based on whether the required controls and payout conditions were met, rather than the size of the loss.
FAQ
Can a cyber warranty replace cyber insurance?
No. A warranty pays defined amounts on specific triggers and is usually secondary to other benefits you hold. Insurance covers a far broader range of losses, is individually underwritten, and is backed by a regulated carrier. Treat a warranty as a layer inside your cover, not a substitute for it.
Can I claim on a warranty and my insurance policy for the same incident?
Yes, and you generally should report to both. Coordinate the two: notify your warranty provider and your insurance carrier, and submit documentation to each. In practice the warranty often covers costs your policy leaves with you, such as the deductible or a business-interruption waiting period.
Which one pays first?
Your insurance policy responds to the covered loss above your deductible. Warranty terms typically require you to exhaust other applicable warranties and financial benefits first, so the warranty helps cover costs left for your business to pay: the deductible, the waiting period and out-of-pocket costs rather than the loss itself.
Is a cyber warranty regulated like insurance?
No. Cyber insurance carriers are licensed and supervised, with solvency requirements and recourse if a claim is handled unfairly. A warranty is a commercial contract: your protection is exactly what the terms say, backed by the issuer. That is why reading the exclusions matters more, not less.
What happens to my warranty if I switch security vendors?
It ends. A warranty is tied to the subscription that carries it, so changing vendor or downgrading your tier removes the benefit. Your insurance policy is yours and moves with you. Factor that difference in if you are weighing a warranty as part of a purchase decision.
Does having a cyber warranty lower my insurance premium?
Not directly, and we wouldn’t claim otherwise. What can influence underwriting is the controls the warranty requires, enforced MFA, active MDR monitoring, immutable backups and a consistent patch cadence are the same controls insurers assess. The security work is what moves the needle, not the warranty document.
