Testing that starts with who would attack you.

A checklist test asks what's broken. A threat-led test asks whether the people likely to come for you could reach what matters most. We scope every test on real adversary tactics, aligned to your systems and your business, then prove which routes in actually work.

Proven by a testObserved in your recordsLikely, from attacks on your sector

Test first: the two routes still marked likely. Fix first: phishing-resistant MFA closes 2 of 3 routes on its own.

Scoped on your business, not a checklist.

Every engagement follows the same five steps, so the test you buy is aimed at the attackers you face and the systems you'd least like to lose.

  1. 1

    Profile the business

    Your crown jewels, key suppliers, sector and the systems the business can't run without.

    You and our consultant
  2. 2

    Model the adversary

    The groups most likely to target you, and the ATT&CK techniques they use.

  3. 3

    Scope on attack paths

    Routes ranked by evidence. The test targets the ones not yet proven, and you sign an authorisation for every host.

    Agreed with you
  4. 4

    Test like the adversary

    Our testers emulate those tactics, from external testing to a full red or purple team.

    Ahlume Cyber testers
  5. 5

    Prove, fix and retest

    Findings land in the testing centre, routes are marked proven or closed, and fixes are retested.

    Tracked in the platform

Nothing touches your systems without your signature.

Every active test needs a signed, in-date authorisation that covers each host. Our platform refuses to send a single packet without one, and records who approved it and when. Agents plan and prioritise; only our testers test.

The testing centre: findings you can track, not a PDF you file.

Request a test, follow it as it runs and work through its findings in one place. Each finding is mapped to ATT&CK and to the attack path it proves, so you can see which fixes close the most routes.
