Security, Elevated.
SECURE YOUR ENTIRE AI STACK
Autonomous Red Teaming
Silmaril simulates attacks on your AI application end to-end through the UI, like a real adversary. It chains AI and Web techniques such as indirect prompt injection, tool abuse, memory poisoning, and more.
Adaptive Blue Teaming
Turn every real exploit into stronger defenses. After human approval, Silmaril retrains guardrails and models and updates configurations, replacing days of manual tuning and test cycles.

BENCHMARKED TO BE THE LEADING HACKER
Pilots Find High/Criticals
Every single run of Silmaril on pilot customers and popular LLM products has resulted in important vulnerabilities being discovered.
Better Than Competitors
In head-to-head benchmarks, Silmaril uncovers significantly more validated exploit chains than competitors and agentic CLI-style tools.
Attack Coverage
Silmaril consistently finds over 90% of hidden exploits in OWASP benchmarking applications in a single run.
Days to Critical Vulns
Silmaril produces signal quickly. In days, it maps your AI surface, chains attacks, and validates them end-to-end.
Sample Exploits
LEARN ABOUT EXPLOITS BY SILMARIL
Open AI
Silmaril used prompt injection to convert the Agent into an attack vector for remote code execution and escalated privilege. Gained access to internal Open AI artifacts including code.
Microsoft
Silmaril found critical prompt injection vulnerabilities using email as the attack vector to achieve data exfiltration through SSRF in Copilot. Patched for millions of users.
