Pre-seed

Building in stealth Your AI agents hold the keys to the kingdom. And your security team can’t watch the door.

DataCitadel sees every move they make, and prevents the worst from happening - before they happen. A security platform for the agentic enterprise, built by people who’ve cleaned up the 3am mess.

UK & EU-domiciled - built for regulated environments.

The new perimeter

Agents move faster than your security team can blink.

Every CISO we’ve spoken to admits the same thing. They don’t actually know what their agents are doing.

They have your credentials.

Agents act on behalf of real humans, with real keys, across real systems - including the ones your team didn’t know they’d authorised. The blast radius is no longer hypothetical.

Nobody is watching.

SIEM was built for users. IAM was built for a time gone by. Agents fall straight through the gap, quietly, at machine speed, and completely outside your control.

Mistakes scale.

One bad prompt. One stale token. One overconfident model. The damage finishes before the on-call pager finishes ringing.

The Citadel

A keep for the agentic enterprise.

Three capabilities. One platform. Works across cloud and on-prem, so the next agent your team ships is already accountable.

01

See

A live, attributed map of every agent, identity, and permission in flight - across cloud and on-premises. Full AI visibility - including the AI your team didn’t know existed.

02

Trace

Every action replayable. Every decision attributable. Audit trails your compliance team will actually love.

03

Stop

Catch the bad ones before they happen. Least privileged access, enforced before the point of action - not surfaced in a report three days later.

There’s more. We’re saving the interesting bits for the people who join the list. See it first →

Who we are

A small team. A loud problem.

We’ve spent our careers building and breaking the security systems that enterprises actually rely on. We started DataCitadel because we kept seeing the same story: brilliant teams shipping AI agents into production with no visibility, no governance, and no fallback - at exactly the moment regulators started paying close attention.

If you’ve lived this story too, we’d like to talk →
