Adrian is the open-source runtime security monitoring and control toolkit for your AI agents. We deploy inside your agents, use reasoning to review the internal chain of thought and block threats before execution.
Agents don't behave like software, your security shouldn't either.
Deterministic → Decision-making
Traditional applications execute deterministic code. Agentic systems make decisions independently.
Static → Adaptive
Traditional software behaves the same every time. Agentic systems adapt based on context and evolving inputs.
Isolated → Tool-driven
Traditional apps operate within fixed boundaries. Agentic systems call tools and external systems to act.
Predefined → Planned
Traditional software follows predefined flows. Agentic systems generate plans before taking action.
Observable → Hidden risk
This introduces a new category of risk: Monitoring output alone is no longer enough.
What we fix
The only agentic AI security tool that blocks, not just watches.
Prompt injection is architectural and will likely never be solved. The best defense is to stop an agent before it executes. To do this effectively, means that your system must evaluate what the agent is planning to do, understand the context, and intervene before harm happens. This is exactlywhat Adrian does.
Monitor
Entire chain of thought coverage
While your agent is planning what to do next, Adrian monitors the chain of thought with our reasoning engine. Not just evaluating input/output. Policing the thought process itself.
Detect
Catches it in the thought
Malicious behaviour, prompt injection, policy violations, out-of-remit reasoning are all detected before any action is taken.
Block
Stops it before execution
Pause the agent. Require human approval. Sandbox the action. You decide the response. Nothing runs until you say so.
HOW IT WORKS
It's as simple as...
01
Connect
Seamlessly integrate your agent framework or orchestration layer within minutes.
02
Observe
Enhance input/output flows with behavioural and contextual signals.
03
Analyse
Apply behavioural interrogation techniques to detect manipulation, drift, and policy violations.
04
Integrate
Leverage existing security triage and operational platforms.
05
Respond
Detect and prevent malicious behaviours; without operational overheads.
How we do it
Security that understands autonomy
Agent-aware monitoring
Built specifically for systems that reason and act — not static applications.
Behavioural intelligence
Moves beyond log inspection to analyse patterns and decision signals.
Low operational overhead
Designed to integrate without slowing development velocity.
Enterprise-first mindset
Focused on long-term reliability, trust, and responsible deployment.
