Our Mission

Built for the
unprotected world.

Every day, hospitals in Kenya, schools in Pakistan, and NGOs in Brazil face ransomware attacks with zero security budget and no one to call. They get the same sophisticated threats as Fortune 500 companies — but none of the resources. Teradef exists to close that gap. Free AI-powered cybersecurity for anyone who has never had any.

Why this exists

In 2026, 37% of NGOs report inadequate cyber resilience versus 11% in the private sector. Ransomware attacks on hospitals surged 36%. And the organizations being hit hardest are the ones that can't afford enterprise security tools or a dedicated security team.

The tools that protect them — incident response frameworks, threat briefings, vulnerability disclosure guidance — exist behind paywalls or inside security firms charging $300/hour. Teradef makes those tools free, instant, and available in six languages.

Who built this

🛡️

Chintan Tailor

SOC Analyst · Founder

I'm a cybersecurity analyst with hands-on experience in SIEM (Splunk, Wazuh), threat detection, incident response, and MITRE ATT&CK. I built Teradef because I kept seeing the same gap — organizations under attack with no guidance, no budget, and no one to call.

This is what happens when domain knowledge meets the right tools. Built in public, one module at a time.

Keep it running

Teradef is funded entirely by voluntary donations. If this platform helped your organization — or you believe in the mission — a small contribution keeps the API costs covered and the platform alive for the next organization that needs it.
