The problem we solve
AI systems expand the attack surface in ways traditional testing misses: untrusted content becomes instructions, tools become capabilities, and retrieval becomes an exfiltration path. We test those paths deliberately and fix what we find.
What the work includes
Data exfiltration testing
Attempts to pull cross-tenant, cross-permission or confidential content through retrieval and tool chains.
Agent abuse scenarios
Tool misuse, privilege chaining, loop and spend attacks against agents with real capabilities.
Defence engineering
Input isolation, output filtering, allow-listed tools, spend caps and permission-aware retrieval implemented, not just recommended.
Continuous assurance
Adversarial suites in CI plus scheduled re-testing as models and prompts change.
How the engagement runs
A sequence you can plan a quarter around.
- 01
Model
Threat modelling across data, tools, identities and trust boundaries.
- 02
Attack
Manual and automated adversarial testing with findings triaged as they land.
- 03
Harden
Mitigation implementation, retest and CI suite handover.
Common questions
Before you commit.
- Can prompt injection be solved?
- Not eliminated. It is contained by treating model output as untrusted and constraining what tools can do.
- Do you work with our security team?
- Yes — findings go into your existing vulnerability process, not a separate report nobody tracks.
