What happened to TrojAI?
discontinued
The URL on file (https://www.troj.ai/) did not
respond across three consecutive checks; the streak completed on
2026-09-23.
TrojAI is a platform that specializes in securing Artificial Intelligence (AI) models and applications from risks and potential attacks. The platform has two key components: TrojAI::DETECT and TrojAI::DEFEND.
TrojAI::DETECT integrates with AI and MLOps workflows to penetration test AI models automatically before they go to production, helping businesses identify hidden risks and vulnerabilities to ensure smooth AI adoption and compliance.
TrojAI::DEFEND protects against real-time attacks using a rules engine underpinned by data science. It also enables secure usage of public AI services by filtering traffic to and from services to block, redact, and audit activity.
In addition, the platform aids organizations to navigate complex regulatory frameworks and benchmarks for AI, helping ensure compliance without slowing down AI adoption.
It tests models prior to deployment to prevent potential sensitive data loss once the applications are in deployment.

How this was decided
Not an editorial call. The URL on file failed three consecutive
checks, with a confirmation re-probe before the streak counted (a
bot-wall response never counts as one), and the 3-miss rule marks the listing
discontinued automatically. If the URL responds again, the
registry restores it on its own: warn first, then
active. Both directions are recorded as events.
