Threat Intelligence-Driven
Vulnerability Management.

SYRN is a vulnerability intelligence platform that aggregates data from 20+ sources (NVD, EPSS, CISA KEV, CERT-FR, ExploitDB, Metasploit, GitHub, and more) and correlates it with your actual technology stack. Instead of drowning in thousands of CVEs, you get a prioritized action plan focused on the threats that matter to your environment.

Create your first perimeter (e.g. "Production Web App"), add your assets and technologies with their versions, and SYRN automatically generates a prioritized Action Plan. The whole setup takes minutes, no agents to install, no complex configuration.

The SYRN Score (0-100) goes beyond CVSS by combining multiple real-world signals: active exploitation status (KEV), exploit availability (ExploitDB, Metasploit, GitHub PoCs), exploitation probability (EPSS), CERT advisories, and your specific asset context. Vulnerabilities with broad evidence of real danger rank highest, so you fix what matters first.

No. SYRN is built for both large enterprises with dedicated cybersecurity teams and SMBs with generalist IT teams. The SYRN Score replaces the jargon: every vulnerability is ranked by priority, with the steps required to fix it. Our AI summaries also remove the need to understand the underlying technical data.

Your Action Plan is a prioritized remediation queue. It shows only the vulnerabilities affecting your configured perimeters and technologies, ranked by SYRN Score. It updates automatically when new CVEs are published, EPSS scores change, or new exploits emerge, so you always see your current risk state.

CVE data is updated continuously, hundreds of times per day. New CVEs appear in SYRN in real time and the database covers the complete NVD history back to 1999.

Yes. The Free plan includes CVE tracking (SYRN score, Threat Intelligence metrics), Trending CVEs, and actively exploited vulnerabilities. It's the easiest way to explore the platform before upgrading to Starter or Pro for perimeter management, action plans, and advanced intelligence features.

The Free plan covers CVE tracking and actively exploited vulnerabilities. Starter adds perimeter management, action plans, advanced filters, and alert rules. The Pro plan extends the limits, adds team collaboration and REST API access. Enterprise offers custom limits, dedicated support, and SLA guarantees.

Yes. The Pro plan and above include a comprehensive REST API that lets you integrate SYRN with your SIEM, ticketing systems (Jira, ServiceNow), CI/CD pipelines, or custom dashboards. Common use cases include pushing high-priority CVEs to Slack/Teams and creating tickets from Action Plan items.

All data is hosted in France by Scaleway, within the European Union. SYRN is fully GDPR-compliant. Cloudflare is used for CDN and security, with data transfers secured by Standard Contractual Clauses.

Define custom rules to get notified when new vulnerabilities match your criteria: severity level, SYRN Score threshold, exploit availability, or specific technologies in your stack. Alerts keep you informed in real time without having to check the dashboard constantly.

No. SYRN is 100% cloud-based. You define your perimeters, map your technologies, and SYRN handles the correlation with threat intelligence feeds. Zero impact on your infrastructure performance.

SYRN doesn't scan your infrastructure — it alerts and prioritizes. If you already have a scanner (Nessus, Qualys, OpenVAS), SYRN complements your stack by telling you, among everything it surfaces, what truly deserves your attention.
