Is defend.network free to use?

Yes. defend.network is completely free with no signup, no paywall, and no account required. Daily threat briefings, live vulnerability reports, and the security tools directory are all open to everyone.

How often is defend.network updated?

A new AI-generated threat briefing is published every day at 04:00 UTC. The vulnerability report is a living document that opens at the start of each week and refreshes daily as new briefings land, with still-exploited CVEs carrying over between weeks. Threat and industry category pages also update daily.

Where does defend.network get its data?

Briefings are synthesized from ten authoritative cybersecurity feeds: CISA advisories, The Hacker News, BleepingComputer, Krebs on Security, Dark Reading, The Record, SecurityWeek, Schneier on Security, HackRead, and Sophos News. Every CVE is cross-checked against the NVD and the CISA Known Exploited Vulnerabilities (KEV) catalog.

How are CVEs and severity ratings verified?

Each CVE mentioned in a briefing or vulnerability report is verified against the National Vulnerability Database (NVD) and the CISA KEV catalog. Severity is derived from the CVSS score and known-exploited status, so reports prioritize what is actually being exploited in the wild.

What does defend.network cover?

Coverage spans 16 threat categories (such as ransomware, phishing, zero-day exploits, and supply-chain attacks), 13 affected industries (healthcare, finance, government, and more), live vulnerability reports with patch-priority guidance, and a directory of 59 security tools across 14 categories.

Who is defend.network for?

defend.network is built for security teams, SOC analysts, IT administrators, CISOs, and anyone who needs concise, verified daily cyber threat intelligence without wading through dozens of news sources.

ABOUT THIS SITE

How It Works

Our methodology →

We monitor

Once a day at 04:00 UTC, the pipeline pulls ten authoritative security feeds – including CISA advisories – and extracts the day’s most important stories and the CVEs they cite.

We verify

Every CVE is checked against NVD for canonical CVSS and cross-referenced with the CISA KEV catalog. Inline citations link each story to its sources, and a skeptical second AI pass flags – or blocks – claims it can’t substantiate.

You act

Severity is scored from CVSS and confirmed exploitation – not editorial tone – so Critical is rare by design. Structured briefings tell your team exactly what to patch, investigate, or escalate.
