A misconfigured firewall is not a gate but a gateway.
Your firewall is your organization's first line of defense — but a misconfigured rule or an unpatched firmware can turn it into an attacker's door. Rules grow complex over time: old policies fade, unnecessary ports stay open, critical firmware updates are delayed. Nobody notices because nobody is auditing.
- Where and how is your firewall rule consistency being verified?
- Does your device firmware contain known CVE vulnerabilities that require patching?
- Are there risky open ports or unnecessary services exposed in your configuration?
What it does.
Configuration and rule audit
Automatically checks firewall rule consistency and risk. Detects unnecessary 'any to any' permits, conflicting rules, outdated standards and missing hardening.
Firmware CVE vulnerability mapping
Device model and version are detected automatically and cross-referenced against the CVE database. Affected version ranges, patch versions and the vendor's security advisory are included in each finding.
Risky open service analysis
Identifies ports unnecessarily exposed to the internet, management services and legacy protocols (Telnet, old SSH). Every finding clearly states why it must be closed.
CVSS-based prioritization
Every finding is rated from critical to acceptable with a CVSS score. A 0–100 risk score and A–F letter grade make it immediately clear what to fix first.
Brand-specific rule catalog
Dedicated rule sets for four brands: FortiGate, SonicWall, MikroTik, Palo Alto. Each includes brand-specific configuration rules, CIS mappings and known CVEs.
Scan comparison and trend
Each scan is compared with the previous one; opened, closed and persisting findings are shown separately. Present health score trends to your auditors with proof.
Shareable evidence-backed report
Findings, risk grades, CVE data, remediation guidance and source distribution become an ISO 27001-aligned PDF for management and auditors.
From setup to report.
- 01
Add device and scope
Add the firewall to the panel: brand, model, management address and access details (API key or SSH).
- 02
Configuration retrieval
CyCastle securely pulls configuration and version information from the device. The CVE database is queried.
- 03
Rule and vulnerability scan
Configuration rule audit, CVE mapping and open service analysis run together. Every finding receives a CVSS score.
- 04
Prioritization and reporting
Findings are ordered by risk score. Category distribution (configuration, CVE, services) is shown and trend is calculated.
- 05
Verification and closure
The next scan verifies closed rules. Closed findings are tagged 'Resolved' in reports and management reviews the evidence.

Frequently asked questions.
Can all my brands be scanned at the same time?
Yes. Each device is scanned automatically when added. Findings from different brands are unified in the panel, grouped by category — you see your entire firewall portfolio's status at a glance.
Where does your CVE data come from?
NVD (NIST) and vendor security advisories. Every CVE record includes version ranges, patch versions and the vendor's official advisory link — your customer can verify the source.
How long does a firewall scan take?
Minutes for simple configurations, 10–30 minutes for complex setups. Configuration retrieval and audit progress are shown in real time on the panel.
