Open Source Intel.
Real Threats. Free.
CyberGuard aggregates the cybersecurity community's best open-source tools, live threat feeds, and free learning resources into one place — so defenders spend less time searching and more time securing.
A Community Aggregator, Not a Vendor
We don't make tools. We don't sell intel subscriptions. We surface what the open-source and public security community has already built.
We aggregate public feeds from CISA KEV, NIST NVD, The Hacker News, BleepingComputer, Krebs on Security, and more — all freely available, all attributed.
Every tool in our directory is open-source or freely available. We link directly to the upstream GitHub repositories and official documentation — no paywalls, no upsells.
Our learning content links to free public resources — OWASP, TryHackMe, HackTheBox, NIST frameworks, and academic courses with no affiliate links.
Battle-Tested,
Open Source
Every tool in our directory is maintained by the security community. These aren't demos — they're the actual tools used by professional red teamers, pentesters, and SOC analysts worldwide.
We verify each tool is actively maintained, link to official repos, and provide context on legitimate use cases. Responsible disclosure is baked into how we present every tool.
The Threat Landscape in 2024–25
All statistics sourced from publicly verifiable databases. Sources linked below each figure.
How We Operate
Transparency over marketing. Community over vendor lock-in. Attribution over aggregation without credit.
Every statistic, every tool listing, every threat advisory links back to its primary source. We are a map, not the territory. Verify everything we show you.
We don't invent team members, user counts, or partnership claims to appear more credible. If we can't verify it, we don't publish it. This page exists because we believe in that principle.
Every offensive security tool we feature includes context on legal, authorized use cases. We follow OWASP's code of conduct and do not assist with unauthorized access.
The security community builds incredible things for free. We credit authors, link to original repositories, and surface maintainer pages — not just tool names.
Our threat feed ranking is not paid. We don't accept "sponsored intel" or SEO placement for tool rankings. CISA and NVD don't charge us — neither do we gate their data from you.
Found something wrong? We publish our contact details prominently and respond to factual corrections. Security is a community sport.
Where Security
People Actually Are
These are the actual communities powering open-source security. We link to them — because the community matters more than any platform.
