Built in UK Defence and Critical National Infrastructure
Defence-grade security for the commercial world.
We test your systems the way a real attacker would. The report satisfies your auditors. The findings tell your engineers exactly what to fix.
What is exposed is only visible when somebody looks.
The practitioner difference.
Built by practitioners who defended the systems the nation runs on.
Your attack surface, mapped by a practitioner
Every assessment is hands-on. We use tooling to move fast, but every finding is validated, tested and confirmed by the practitioner doing the work.
Audit-ready in days
Reports mapped to the frameworks your auditors and investors are already asking about. No scramble, no last-minute gaps.
From finding to fix
We don't hand over a PDF and walk away. Every finding is written up, prioritised and ready for your team to act on the same day.
Two tracks, one standard
A standalone assessment or an ongoing offensive security partnership. Either way, the same senior engineers, the same rigour, no hand-offs to juniors.
A reply within one business day
From your first message to an answer from the engineer doing the work. No sales team, no ticketing system, no wait.
Fluent in code and the boardroom
Technical findings your engineers can act on, and risk reporting your board and investors can understand.
Most security testing is built to pass an audit. Ours is built to stop an attacker.
Most providers hand you a PDF and move on. We stay until your team has fixed it.
− Most security testing
+ Tarian Labs
Automated scans packaged as penetration tests
Engineers who approach your systems the way an attacker would
A PDF report handed over and never mentioned again
Assessments that move with your environment, not against it
Security considered after the build is already done
Security that shapes decisions before they become technical debt
Findings written for compliance, not for your engineers
Structured findings your team can pick up and act on the same day
No support once the report lands in your inbox
Hands-on support until the vulnerability is fixed, not just documented
Don’t take our word for it.
“Tarian Labs did not just run the usual scans and call it a penetration test. They worked through the tool output and discarded what did not hold up, then showed us what the real findings meant in our environment, including a route to Global Administrator we believed we had already closed.”

Read the case study: UK Managed Service Provider“What impressed us most was the integrity of the assessment. Tarian Labs gave us an honest, evidence-based evaluation of our security posture rather than inflating findings to justify the engagement. That kind of straightforwardness is exactly what you want from a security partner.”
