Compare 13 UK Cyber Essentials implementation partners delivering Cyber Essentials and Cyber Essentials Plus certifications for suppliers to UK central government, the NHS, defence, and regulated buyers who require the certification as a procurement gate. Engagements cover the scoping decision across whole-organisation or scoped certifications, the gap assessment against the five Cyber Essentials control themes (firewalls, secure configuration, user access control, malware protection, and security update management), the remediation of the most common findings including unsupported operating systems, missing MFA on cloud accounts, weak password policies, and gaps in user-access provisioning and leaver routines, the Cyber Essentials Plus on-site test by an IASME-certified assessor covering vulnerability scanning and MFA verification, the bring-your-own-device and cloud-services scope clarifications, and the annual renewal cycle. Listings cover IASME-certified bodies, UK managed security service providers, India-heritage SIs serving UK delivery, and the SME-focused boutiques. No partner pays for placement on this directory.
Cyber Essentials programmes break into four typical workstreams. Scope definition, where the partner clarifies whether the certificate covers the whole organisation or a scoped business unit, identifies the in-scope devices including end-user computing, servers, cloud services, and BYOD where users access organisational data, agrees the cloud-services boundary under the Cloud Services scope clarifications updated in the Montpellier and Willow question sets, and clarifies the home-working device treatment. Gap assessment and remediation, where the partner runs the SAQ-style assessment against the five technical controls, identifies the common gaps including end-of-life operating systems, missing MFA on cloud admin accounts, gaps in starter-mover-leaver provisioning, weak password and account-lockout policies, missing patching SLAs, and gaps in malware protection on Mac and Linux estates, and runs the remediation plan. Cyber Essentials submission, where the partner supports the organisation through the IASME Cyber Essentials portal SAQ, validates the answers against the question-set guidance, and submits for assessor review. Cyber Essentials Plus on-site verification, where an IASME-certified assessor runs vulnerability scans on a sample of devices, validates MFA on cloud services, tests EICAR malware controls, and validates the patching evidence.
Three procurement archetypes recur. IASME-certified assessment bodies (IASME, Nettitude, BSI, CSG, Indelible Data, CQR, Evalian) are the only firms authorised to issue Cyber Essentials and Cyber Essentials Plus certificates, and most lead both the remediation and the certification audit unless the buyer prefers separation. UK managed security service providers and MSPs (Bulletproof, Ramsac, Pentest People, CyberOne) lead at mid-market buyers needing combined MSSP and CE delivery, often bundling vulnerability scanning, EDR, and remediation. India-heritage SIs (TCS, Infosys) lead on large UK supplier programmes where Cyber Essentials sits inside a broader cyber posture for UK central-government and defence supplier contracts. Friction point: Cyber Essentials Plus has tightened materially since Willow (April 2025) on cloud services, MFA verification, and BYOD scope. Suppliers who passed CE Plus three years ago routinely fail their first Willow audit on the cloud and MFA questions even when underlying controls have not regressed, and a Cyber Essentials Plus certificate alone does not satisfy buyers requiring ISO 27001 or NHS Data Security and Protection Toolkit assurance.
