Cyber Insurance Firewall Readiness
Fix what the carrier's scanner will find
before they find it.
Cyber insurers scan your exposed firewall and VPN appliance starting at the application stage, then roughly every 30 days after you're bound. CRWLR audits the same exposure — plus the internal rule hygiene a perimeter scan can't see — and hands you a report for your broker.
No agent, no insurer integration, no account required to see the demo. Raw config parsed in memory and discarded. Free posture score in under 60 seconds.
Scanned before you even apply
Coalition, one of the largest cyber insurance carriers, fingerprints your internet-exposed ports, services, and device/firmware versions starting at the application stage — and keeps scanning roughly every 30 days after you're bound.
Fix the exposure, not just the paperwork
Exposed management interfaces, risky port-forwards and VIPs, deprecated VPN settings, and outdated firmware with known CVEs — the exact class of finding an outside-in carrier scan surfaces.
Something real to hand your broker
A posture score, prioritized findings, and vendor-specific CLI fixes, exportable as a report — evidence that you looked, not just a box you checked.
What carriers actually require — and what they actually see
Published headline requirements (Coalition)
- –Multi-factor authentication (MFA)
- –Security awareness training
- –Data backups
- –Identity & access management
- –Data classification
A firewall configuration audit is not one of the five.
What the outside-in scan sees
- –Open ports and exposed protocols on anything internet-facing
- –Device and firmware version indicators (CPE) — visible for an exposed firewall or VPN appliance
- –Nothing about internal rule quality — segmentation, business justification, and Threat Prevention assignment are invisible to an outside-in scan
We're not going to tell you carriers mandate a config audit — they don't. What they do is scan your perimeter before they price you and every renewal after. Per Coalition's own Cyber Threat Index, an internet-exposed Fortinet device carries roughly 2x the claim likelihood, and an exposed Cisco ASA roughly 5x. Clean that up before the carrier's scan does it for you.
What CRWLR finds that closes the gap
HTTPS admin interface reachable from any on WAN1
Policy wan1-mgmt-access allows HTTPS management access to the firewall from any source address on the internet-facing interface. This is exactly the kind of exposure an external attack-surface scan fingerprints — and one of the fastest fixes available before an application or renewal scan runs.
config firewall policy
edit <policy-id>
set srcaddr "trusted-admin-subnet"
unset srcaddr "all"
next
end
config system interface
edit "wan1"
unset allowaccess
set allowaccess ping
next
endEvery finding ships with the exact CLI fix for your platform, the policy or object that triggered it, and a plain-English explanation of what changes once you apply it.
Built for two situations
Facing an application or renewal questionnaire
You're the SMB owner or IT lead about to submit a cyber insurance application, or a renewal is coming up and you'd rather not find out what the underwriter's scan turned up after the fact. Run the audit first, fix what it finds, then fill out the questionnaire with a clean perimeter and a report to back it up.

Sanitize & upload
Strip secrets client-side with the free sanitizer, then upload the export. The raw config is parsed in memory and discarded — never stored.
Score & findings
A 0-100 posture score plus prioritized findings covering exposed management, port-forwards, VPN, and firmware CVEs — in under 60 seconds.
Export for your broker
Download the report and hand it to your broker or underwriter alongside the application or renewal questionnaire.

Frequently asked
Do cyber insurance companies actually scan my network?
Yes — at least the part of it visible from the internet. Coalition, one of the largest cyber insurance carriers, scans an applicant’s external attack surface starting at the application/quote stage, not just after the policy binds. It keeps scanning afterward too: a full refresh of your public IP footprint roughly every 30 days, with higher-priority ports checked faster. Findings feed into pricing at quote time, and issues left unresolved can create contingencies at renewal.
Do insurers require a firewall configuration audit?
No — and we won’t tell you otherwise. Coalition’s own published list of five essential requirements is multi-factor authentication, security awareness training, data backups, identity and access management, and data classification. A firewall config audit is not one of them. What carriers do require, functionally, is that your internet-exposed footprint looks clean when they scan it — that’s a different problem than a mandate, and it’s the one this page is about.
What does a carrier’s scan actually see — and what does it miss?
It’s outside-in only. A carrier’s scanner fingerprints open ports, exposed services and protocols, and device or firmware version indicators on anything reachable from the internet — including your firewall or VPN appliance. It never sees your internal ruleset: whether a permissive rule is business-justified, whether east-west segmentation holds, whether a Threat Prevention profile is actually assigned to the gateway that needs it. A config audit covers both ends — it fixes what the scanner will find (exposed management interfaces, risky port-forwards, deprecated VPN settings, outdated firmware with known CVEs) and it covers the internal hygiene the scanner can’t see at all.
How do I prepare my firewall before a cyber insurance application or renewal?
Run a config audit before you submit the questionnaire, not after a carrier flags something. Upload a sanitized export of your firewall config (the raw config is never stored) and CRWLR returns a 0-100 posture score, flags exposed management interfaces, risky port-forwards and VIPs, deprecated VPN settings, and firmware with known CVEs — cross-referenced against CISA KEV, NVD, and vendor advisories such as Fortinet PSIRT. You get vendor-specific CLI fixes for each finding and an exportable report to hand your broker alongside the application.
Can an MSP use this to prepare client estates for applications or renewals?
Yes. Bulk import scans a whole client estate in one pass, with each config parsed in memory and isolated per tenant — nothing crosses between clients. Add a pre-renewal firewall review to what you already do ahead of a client’s cyber insurance application or renewal. See /msp-firewall-audit-software for fleet pricing and white-label reports.
Does CRWLR check for the specific exposure that raises claim risk, like an internet-facing Fortinet or Cisco ASA device?
Yes. Coalition’s own Cyber Threat Index reports internet-exposed Fortinet devices at roughly 2x claim likelihood and exposed Cisco ASA at roughly 5x. CRWLR audits both platforms — plus Palo Alto, Sophos, and Check Point — for the exposure patterns behind that risk: unrestricted admin access, risky port-forwards, and firmware with known CVEs, alongside the internal rule hygiene a perimeter scan can’t see. 175 checks total across all five vendors.
