Cyber Insurance Requirements in 2027: What Underwriters Actually Demand Before They’ll Bind Coverage

The soft cyber market is over. Underwriters have learned what actually reduces claims, and they are pricing coverage against it. If you haven’t had a serious conversation about your controls before your 2027 renewal, you will have one during it.

How the Cyber Insurance Market Got Here

Cyber coverage in 2018 was a courtesy line item. Carriers wrote broad limits with light questionnaires and priced generously. Then ransomware losses tore a hole in the market. Between 2020 and 2023, loss ratios spiked, capacity contracted, and every carrier that stayed rewrote how they underwrite. The 2024–2026 market stabilized — but on new terms.

Those new terms are:

• Detailed technical questionnaires that carriers actually verify.
• Ransomware sub-limits and coinsurance for organizations without required controls.
• Exclusions for war, systemic infrastructure events, and unremediated known vulnerabilities.
• Real willingness to non-renew accounts that don’t maintain a required control posture.

The Baseline Controls Every Carrier Now Expects

Individual carriers word the requirements differently, but the substantive list overlaps almost completely across major markets.

1. Multifactor Authentication — Broadly Deployed

Not just for email. Carriers now expect MFA on:

• All external remote access (VPN, RDP, Citrix, VDI).
• All email accounts — without exception.
• Administrative accounts of all kinds, including privileged cloud roles.
• Any interface used to access sensitive data or move funds.

Some markets now push further and require phishing-resistant MFA (FIDO2, passkeys) for privileged and finance-adjacent accounts.

2. Endpoint Detection and Response — With 24×7 Monitoring

Traditional antivirus alone will get you declined at most markets. Carriers expect an EDR or XDR platform deployed on all endpoints and servers, with 24×7 monitoring either by an internal SOC or a Managed Detection and Response (MDR) provider. Coverage gaps — even a small percentage of unprotected machines — are a real underwriting problem.

3. Immutable, Air-Gapped Backups — Tested

The ransomware-loss experience taught carriers that a business without recoverable backups is a business that pays the ransom. Underwriters expect:

• Backups that cannot be modified or deleted within a defined retention window.
• Backups that live on infrastructure separate from the production identity plane.
• Documented, recent restore tests.

The specific “3-2-1-1-0” wording appears in a lot of underwriting guides now: three copies, two media, one off-site, one immutable, zero errors on restore test.

4. Email Security — Beyond Native Filters

Given the size of the BEC problem, carriers expect layered email security: strong domain protections (SPF, DKIM, and enforcement-mode DMARC), inbound URL rewriting or advanced threat protection, and mailbox-rule auditing. A business relying only on default filters will face questions.

5. Privileged Access Management

Underwriters increasingly ask how administrative rights are controlled. That means:

• Separation of daily-use and administrative accounts.
• Just-in-time elevation where possible.
• Vaulted, rotated, monitored credentials for the highest-privilege accounts.
• Removal of local-admin rights from standard user machines.

6. Security Awareness Training — Documented

Annual is the floor; most carriers prefer quarterly. What matters is that training is documented: dates, topics, completion rates, phishing simulation results. “We talk about security in the all-hands sometimes” is not an answer.

7. Incident Response Plan — Written

A named plan, with named roles, tested at least annually with a tabletop exercise. Carriers reward businesses that can produce the document during application. They penalize those that write it during a claim.

8. Patch and Vulnerability Management

Documented patching cadences for endpoints and servers — especially internet-facing systems. Underwriters now cross-reference application answers against external scans of your public IP space; unremediated known vulnerabilities on those scans will draw exclusions or premium loading.

Controls That Are Rapidly Becoming Standard

Newer to the requirement list, but rising quickly:

• Network segmentation that isolates OT/ICS, guest networks, and high-value assets.
• Data classification and DLP for regulated industries.
• Third-party risk management — formal assessment of the vendors that touch your data or systems.
• Managed vulnerability scanning with documented remediation SLAs.
• Cyber tabletop exercises beyond IT, involving leadership, legal, and communications.

What Non-Compliance Actually Costs You

The consequence of falling short of expected controls varies by carrier, but the common patterns are:

• Sub-limits on ransomware coverage — sometimes 25–50% of the aggregate.
• Coinsurance clauses that force the insured to co-pay a portion of ransomware losses.
• Premium loading of 20–100% relative to a well-controlled peer.
• Non-renewal at the end of the current policy term.
• Denial of a specific loss when it’s traced to a missing required control.

Preparing for a 2027 Renewal — 90 Days Out

• Days 1–30: Pull last year’s application. Rebuild the control inventory against it. Identify every “yes” that is not fully supported by evidence.
• Days 31–60: Close the top three control gaps — typically MFA coverage, EDR deployment, and backup immutability. Document everything.
• Days 61–90: Run a tabletop exercise. Refresh the incident response plan. Update the risk assessment. Assemble the evidence packet the underwriter will ask for.

Businesses that come into renewal with a clean, well-documented packet consistently get better terms — and often are able to increase limits at flat or reduced pricing. Businesses that hand the broker a half-finished questionnaire in month twelve get what they get.

Working With Your Broker

A good cyber broker in 2027 is a partner, not a paper-pusher. They should:

• Tell you which markets are appetite-friendly for your industry and size.
• Help you translate technical controls into underwriter-friendly language.
• Warn you which controls are likely to become deal-breakers in the coming renewal cycle.
• Coordinate with your IT and security teams — not just your risk manager.

If your current broker is not doing these things, that is a data point about the value they are actually delivering.

Bottom Line

Cyber insurance in 2027 rewards controlled organizations and penalizes uncontrolled ones. That is by design. The good news: the same controls that make you insurable are the ones that reduce the probability and severity of an incident in the first place. Preparing for a renewal is not overhead — it is your security program on a fixed calendar.

Brightworks IT works alongside our clients’ brokers to prepare defensible renewal packages and close the control gaps that drive pricing. Reach out if your 2027 renewal is on the horizon and you’d like a second set of eyes before it lands.
