ASTRA agentic security

ASTRA. The crash test for AI agents.

Before an agent is trusted to act, ASTRA attacks it with the exploits attackers would actually use — and proves how it can be turned against you.

The question

Identity says who.
But is it safe?

Fingerprinting answers who is acting — identity, operator, runtime
ASTRA answers can it be turned — injection, tool abuse, token misuse

A valid, authenticated agent can still be manipulated into acting against its purpose. Whether it can be turned is a separate question — and it is the one ASTRA answers.

The exploits ASTRA uses

Real attacks, not a checklist.

PI 01 / 03

Prompt Injection

Malicious instructions hidden inside the inputs an agent reads — documents, emails, tool output.

crafting exploit… probing agent… outcome blocked · input quarantined
TC 02 / 03

Tool-Call Attacks

Abusing the connected tools an agent is trusted to use — chaining benign calls into a harmful one.

TM 03 / 03

Token Misuse

Turning an agent’s credentials and budgets against it — scope creep, replay, exfiltration.

How ASTRA works

Model. Explore. Harden.

01 no benchmark required

Model

Maps how agents fail and generates millions of violation-inducing attacks tailored to the target.

  • target: procure-agent · 12 tools · pays vendors
  • failure map: over-trusts retrieved docs, chains tools
  • generated 2.4M attack variants · 20+ classes
attack corpus 2.4M variants
02 multi-turn

Explore

Conversations follow the agent’s reasoning to the exact step it breaks — and record the trajectory.

  • turn 4 · agent reads poisoned invoice memo
  • turn 7 · calls update_bank_details on request
  • turn 9 · attempts transfer_funds — break recorded
break point turn 9 of 14
03 enforceable

Harden

Every violation becomes safety training and enforceable limits the agent carries into production.

  • limit: transfer_funds requires step-up > $1k
  • limit: memo fields read-only · no instructions
  • retest every 7d · on model or tool change
controls issued 3 limits · retest 7d

The evidence

Not a report. A control.

Every weakness becomes a machine-readable trust signal — manipulation paths, failure modes and susceptibility under pressure — with the reasoning trajectory that produced it.

The loop-back

Weakness becomes authority.

That signal sets the agent’s supervision level, tool limits and retest cadence — and becomes the qualification baseline Agentic Fingerprinting re-proves in production.

Agent ASTRA attacking Trusted

Qualify the agent
before you trust it.

ASTRA attacks first, so attackers don’t get to. Every exploit it finds becomes a limit the agent can’t cross.
