Got a suspicious file? Search its hash against 6.9M known malware samples in 3 seconds. Free, no signup needed. We also built a free open-source SIEM that installs in 60 seconds with one command — includes AI threat detection, 52 detection rules, vulnerability scanning against 27K+ CVEs, and tamper-proof blockchain log anchoring. Security tools cost $2K+/month. Ours are free. Because threat intelligence should be a public good, not a paywalled luxury.

I built ThreatChain because I was tired of paying thousands of dollars a month for basic security tools that should be free. As a penetration tester, I use threat intelligence daily — checking file hashes, looking up CVEs, monitoring logs. Every tool that does this well costs $50-$300/month. VirusTotal, Shodan, Splunk — all paywalled. So I built the alternative: - Search 6.9M malware hashes instantly (free, no signup) - Open-source SIEM that installs in 60 seconds - AI-powered threat detection with 52 detection rules - Vulnerability scanner covering 27K+ CVEs - Tamper-proof blockchain log anchoring The SIEM is fully open source on GitHub. The search engine is free at threatchain.io. Would love feedback from the security community — what features matter most to you?
