Why Snubnose

Everything you need for Level 0.
In one workspace.

Scoping, evidence, and assessor review, with a guided path from day one.

01

Clear requirements.

Understand exactly what Level 0 requires. Plain-English breakdowns of every control mapped to DefStan 05-138, so you never have to guess what "good" looks like.

No interpretation roulette. Every control, explained.

02

Self-guided scoping.

Walk through sites, systems, data, and people at your own pace. Our guided workflow builds your scope register and attestation as you go, nothing left behind.

Scope defined in hours, not weeks of workshops.

03

Evidence that assessors can actually read.

Upload a policy, register, or screenshot and our AI validates it against the control before your Assessor ever sees it. Every artifact is tagged, versioned and annotated, so your audit pack is ready the moment the last upload lands.

Fewer iterations. Fewer clarifications. Faster sign-off.

What Level 0 covers

Three controls.
One certification.

DCC Level 0 is the entry-level certification under DefStan 05-138, for suppliers with a very low assessed cyber risk. It is built around three controls.

Cyber Essentials

The pre-objective for Level 0. If you already hold Cyber Essentials or Cyber Essentials Plus, you are most of the way there.

UK GDPR compliance

Demonstrate that the personal data you hold is protected by appropriate UK GDPR processes and controls.

Resilient networks and systems

Show that your networks and systems are designed and maintained to keep running when something goes wrong.

For official guidance, see the DefStan 05-138 publication on GOV.UK, or read our plain-English guide.
