Agentic AI
External Security Testing.

Responding to cyber incidents has shown us attackers identify and exploit weaknesses faster than ever using automation and AI driven weapons.

Attackers can fail thousands of times, but when an organisation fails once, the impacts can be catastrophic.

Attackers use AI tools to understand an organisation's cyber exposure; often knowing more than the organisations does.

Vulnerable APIs
Accessible infrastructure

Cyber attacks are launched continuously at machine speed.

Thea is your cyber security safety net to help you level the playing field.

How it works

Our service is an autonomous security testing engine built on a controlled agentic AI architecture. It plans, tests, validates and reports with human oversight at critical points.

Why our approach

Manual penetration tests are thorough but periodic. Vulnerability scanners are continuous but often noisy. Generic AI tools can identify issues but frequently lack validation and context.

Thea combines continuous assessment, offensive testing techniques, and evidence-backed validation to provide a more accurate view of real-world security risk.
