Offensive security
built for the AI stack
Krypteia Sec is an independent AI security practice focused on adversarial testing of LLMs, agents, MCP servers, and the systems built on top of them.
Who We Are
Krypteia Sec is an offensive security practice purpose-built for AI systems. Our work focuses on the surfaces that traditional pentest firms still treat as out of scope: large language models, autonomous agents, MCP servers, retrieval pipelines, and the integrations that connect them to production data and real-world actions.
We pair deep red team experience with offensive AI engineering. Engagements are delivered by operators who design and ship the autonomous hackbots used in the assessments themselves, then convert findings into clear, prioritized recommendations.
Independent. Research-driven. Focused on the AI surface that other firms have not yet learned to test.
What We Test
Every layer of the AI stack has its own attack surface. Testing just the LLM is like testing only the front door while ignoring every window. We test the full spectrum.
Large Language Models
System prompt extraction, jailbreaking, guardrail bypass, alignment manipulation, output steering, and adversarial prompt construction.
AI Agents
Tool exploitation, permission escalation, MCP bridge attacks, memory poisoning, and multi-step kill chains through autonomous systems with real-world access.
RAG Pipelines
Vector database poisoning, retrieval context manipulation, document injection, and upstream training data corruption that propagates through the entire stack.
AI Chatbots
Business logic bypass, policy override attacks, data exfiltration through conversation, PII leakage, and multi-turn social engineering at scale.
ML Pipelines
Model extraction, training data poisoning, adversarial input generation, evasion techniques, and supply chain attacks on model dependencies.
AI-Powered Applications
End-to-end testing of any application with AI components. API integrations, workflow automation, and the gaps between traditional software and AI layers.
Our Mission
Build autonomous AI hackbots that test every AI system before it goes into production. Not manually. Not with checklists. With agentic AI that thinks like an attacker, adapts in real time, and chains vulnerabilities into kill chains that no static scanner would find.
The gap between AI deployment speed and AI security testing is the largest unaddressed risk in enterprise technology right now. Every organization deploying AI is deploying untested AI. We exist to close that gap.
The Vision
Every AI system should be adversarially tested before deployment. Not by humans running prompt lists. By autonomous hackbots that understand language, maintain strategic state across conversations, and adapt their attacks based on what they learn.
We are building toward a future where agentic AI penetration testing is automated, accessible, and standard practice. Where organizations test their LLMs, agents, RAG systems, and chatbots with the same rigor they test their network perimeter.
Everything we build is open. Everything we learn is published. The blog is where we share research. The repos are where we release tools. Open knowledge makes the whole ecosystem stronger.
We build AI that breaks AI, so you can build AI that works.
What We Stand For
Offensive Mindset
Think like an attacker. The best defenses are built by those who understand how systems actually break, not how they are supposed to work.
Open Research
Security through obscurity fails. We publish our tools, our taxonomy, and our findings. Open knowledge makes the entire ecosystem stronger.
AI-Native Testing
AI vulnerabilities are semantic. They live in meaning, not in bytes. The only thing that can probe meaning at scale is another AI. We build that AI.
