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.

• CyberWeatherWeekly AI threat briefings tailored to your organization type and region. Plain language. Actionable. Like a weather forecast for cyber risk.

Who built this

Chintan Tailor

SOC Analyst · Founder

I'm a SOC Analyst with hands-on experience in SIEM platforms (Splunk and Wazuh), threat detection, incident response, and the MITRE ATT&CK framework.

I watched hospitals, NGOs, schools, and activists face the same advanced attacks that large enterprises spend millions to defend against — except these organizations had zero dedicated security team, zero budget, and no one to call at 2 a.m.

That gap shouldn't exist. So I built TeraDef — a completely free, instant, AI-powered cyber defense platform designed for those who have never had any. No team. No budget. No vendor lock-in. Built solo, in public, one module at a time.
