What we cover
Practical, board-ready consulting — no jargon, no surprise invoices.
Cyber Essentials — Self-assessment support
We don't charge for the self-assessment pathway itself — your IT can complete the questionnaire with an accredited body. We help where you want a quick sanity-check of your answers (1-2 hours consulting) to avoid a fail-on-first-attempt.
Cyber Essentials Plus — readiness engagement
Our fixed-price readiness — gap audit, remediation plan, pre-test scans, evidence pack assembly, assessor coordination. Scoped to your user count and sites.
Cyber Essentials Plus — assessment body fee
The certification body's own fee, passed through at cost, scaling with sites and complexity. Contact us for a tailored quote.
Annual renewal readiness
Plus certificates expire after 12 months. We offer a 1-day renewal audit (plus optional monthly monitoring) to keep you between-cycle clean and avoid fail-on-renewal.
Pre-tender readiness pack
You're bidding on a UK government framework — Cyber Essentials Plus is required by 5pm Friday. We compress the gap audit + remediation cycle to 10 working days plus assessor coordination.
ICO / configured evidence packs
Post-assessment, your Plus certificate is in hand. We bundle ongoing evidence — MFA coverage reports, conditional access exports, leaver/joiner audit trail — as needed.
How we work
Quote (Day 0)
15-minute scoping call. We confirm user count, sites, current Microsoft 365 / Entra posture, and contract deadline. Fixed-price quote next working day.
Audit (Week 1)
Internal audit against the 5 CE Plus requirements. Output: a prioritised fix-list with cost impact and timeline. No work begins until you sign off.
Remediation (Week 2-3)
We and your IT implement the agreed fixes. Half-day sessions, not weekly retainers — you see line-items and can stop at any point.
Pre-test (Week 4)
We re-run the scans the assessor will run. Anything still failing we strip back.
Assessment (Week 5)
Assessor on-site. We sit alongside. Pass within 5 working days of the assessment.
