defend.network is a free, no-login cybersecurity intelligence site for security teams and defenders. It publishes a daily AI-generated threat briefing and a living weekly vulnerability report, structured by threat type, industry, and severity.
Every CVE it reports is cross-checked against the U.S. National Vulnerability Database (NVD) and the CISA Known Exploited Vulnerabilities (KEV) catalog before publication, and enriched with CVSS severity and FIRST EPSS exploitation-probability scores โ so you can quickly see what is being actively exploited and what to prioritize, with remediation notes.
It also includes a security-tools comparison directory. All content is free with no signup, no paywall, and no ads, and is available via RSS and a free, CC BY 4.0-licensed JSON API. defend.network is an independent project (not a vendor): its methodology and sources are published openly, and it does not run paid reviews or sponsored rankings.
