← Compliance Library Cyber insurance preparation

The evidence binder
your broker is asking for.

Underwriters want proof, not promises. Our infrastructure produces the control documentation that gets you covered — and keeps premiums from climbing.

Overview

What underwriters
actually want.

Cyber insurance underwriting has fundamentally changed. Where applications once asked “Do you have a firewall?” (yes/no), modern questionnaires demand specific technical controls with evidence of implementation. Underwriters now employ technical scanning and require attestations about specific security configurations.

The controls insurers consistently require include: email authentication (SPF, DKIM, DMARC), encryption in transit (TLS 1.2+, HSTS), vulnerability management (patch currency, scanning), and DNS security (DNSSEC, proper configuration). These aren’t optional — carriers now decline coverage or exclude claims for organizations missing these basics.

More critically, insurers are denying claims post-breach when they discover that attested controls weren’t actually operating. A 2024 Coalition report found that organizations with verified email authentication pay 25% lower premiums and experience 30% fewer claims. The ROI on provable security is measurable.

PrismWeb’s sixteen checks map directly to the questions on major carrier applications (Coalition, Corvus, At-Bay, Resilience, Cowbell). We don’t just help you answer “yes” — we produce the evidence that survives a claims investigation.

Underwriter requirements

Controls that affect
your premium.

Check Insurer Requirement Premium Impact
DNSSEC DNS security configuration Moderate — differentiator
SSL/TLS Encryption in transit (mandatory) High — coverage requirement
Enhanced HTTPS HSTS, forced encryption Moderate — premium reduction
Enhanced TLS TLS 1.2+ minimum, strong ciphers High — coverage requirement
Certificate Validation Valid certificates, proper trust chains Moderate — basic hygiene
Security Headers Application hardening controls Moderate — differentiator
SPF Email authentication (mandatory) Critical — often required for coverage
DKIM Email authentication (mandatory) Critical — often required for coverage
DMARC Email policy enforcement (mandatory) Critical — claims denied without it
MTA-STS Email encryption enforcement Moderate — advanced differentiator
TLS-RPT Security monitoring and reporting Low — demonstrates maturity
IP Abuse Reputation/blacklist monitoring Moderate — incident indicators
WordPress Detection Patch management, vulnerability tracking High — outdated CMS is red flag
Website Scanning Regular security assessment Moderate — continuous monitoring
IPv6 Infrastructure modernization Low — demonstrates investment
RPKI Network routing protection Low — advanced differentiator
Evidence production

What we hand
your broker.

01
Application Support Package

Pre-answered responses for common carrier questionnaires (Coalition, Corvus, At-Bay, Resilience) with supporting evidence for each attestation. Your broker gets documentation, not just checkboxes.

02
Security Posture Report

A current-state security assessment showing all sixteen checks, their status, and trending data. Underwriters love trending data — it shows controls operate over time, not just on the day you applied.

03
Claims Defense Documentation

If you ever need to file a claim, timestamped evidence that controls were operating at the time of incident. Insurers can’t deny claims for “failure to maintain controls” when you have continuous verification records.

04
Renewal Evidence Package

Annual renewal packages showing security posture improvements, maintained controls, and any incidents with documented remediation. The data that keeps premiums from escalating at renewal.

05
Premium Reduction Justification

Documentation your broker can use to negotiate lower premiums based on verified security controls. Organizations with our level of email authentication and encryption verification typically qualify for preferred rates.

Pay less when you do.

Your broker needs evidence, your underwriter needs confidence, and your claims team needs proof. Our infrastructure produces all three — automatically.
