What it covers

Five controls. One certificate. The baseline the UK government trusts.

Cyber Essentials assesses five technical controls that, between them, protect against the most common cyber attacks. Every device in scope — including home working devices — must meet all five.

01

Firewalls

Every device that connects to the internet needs a boundary firewall — correctly configured to block traffic that has no reason to reach it. This includes devices working from home, not just those in the office.

02

Secure Configuration

Devices and software must be configured securely before deployment. Default passwords changed, unnecessary features disabled, accounts removed when no longer needed. Most breaches exploit the defaults that nobody changed.

03

User Access Control

Only people who genuinely need access to a system or dataset should have it. Standard accounts for day-to-day work, admin accounts only used when necessary, and access removed promptly when someone leaves.

04

Malware Protection

Protection against malicious code — through anti-malware software, application whitelisting, or sandboxing — applied consistently across all devices in scope.

05

Patch Management

Software vulnerabilities are published regularly and exploited fast. Cyber Essentials requires that operating systems and software are kept up to date — patches applied within fourteen days of release for high-severity vulnerabilities.

Based in London

Looking for a Cyber Essentials company in London?

Plenty of firms will sell you the questionnaire. Fewer will build the environment underneath it, and fewer still are based where you are. Little Big Tech is a London and South East MSP that holds Cyber Essentials certification itself, and manages the IT of the businesses we certify day to day, not just at renewal time.

That matters because your Technology Resilience Score™ does not stop moving once the certificate is issued. Below 3.0 is elevated risk; 3.5+ is typical for similar organisations. Getting the five controls genuinely in place is what moves you from one to the other, across access control, device management and security protection, and a managed IT partner keeps you there. A certification company that disappears after the audit cannot tell you that. We can, because we are still managing your environment the following month.

Why your sector needs it

Cyber Essentials is required, expected or rewarded in every sector we serve.

The trigger is different in each sector. The underlying requirement — documented, verified security controls — is the same.

Law Firms & Solicitors

Required for many legal panel memberships. Cyber Essentials aligns with SRA data security guidance and supports Lexcel accreditation — and professional indemnity insurers are increasingly asking to see it at renewal.

IT support for Law Firms & Solicitors →

Financial Services & IFAs

Cyber insurers increasingly require Cyber Essentials as a condition of cover or a basis for calculating premiums. It also demonstrates the documented security controls that support FCA operational resilience expectations under Consumer Duty.

IT support for Financial Services & IFAs →

Private Healthcare

The Data Security and Protection Toolkit (DSPT) requires healthcare providers to evidence cyber security controls equivalent to Cyber Essentials. NHS supply chain contracts require Cyber Essentials Plus.

IT support for Private Healthcare →

Accountants & Accountancy Practices

ICAEW and ACCA practice reviewers and professional indemnity insurers look for evidence that client financial data is protected. Cyber Essentials provides the documented, verified baseline that makes that conversation straightforward.

IT support for Accountants & Accountancy Practices →

SMEs in General

Central government contracts require Cyber Essentials for work involving personal data or ICT services. Enterprise clients running procurement due diligence routinely ask for it. And cyber insurers across all sectors are tightening their requirements.

How we do it

We build the environment first. The certificate follows.

Most Cyber Essentials providers help you fill in the questionnaire. We take a different approach: we start by building the IT environment that genuinely meets the five controls, then guide you through the certification process. The certificate reflects reality — which matters when your panel membership sponsor, indemnity insurer or enterprise client actually looks behind it.

A pre-assessment check identifies where your current environment falls short of the five controls. We close those gaps — correctly configuring firewalls, tightening access controls, ensuring patch management meets the required window, reviewing devices in scope including those used at home. Once your environment genuinely meets the standard, the assessment itself is straightforward.

Cyber Essentials certification also maps directly to your Technology Resilience Score™. The five controls cover security protection, passwords and access control, and device management — areas the TRS™ measures independently. Achieving certification typically moves a firm from a TRS™ of 2–3 to 3.5 or above in those dimensions. It is the baseline. Your score shows what comes next.

“The team at Little Big Tech have transformed our backup and storage situation. Working with our quite specific infrastructure setup, they've deployed a network storage system we can trust. Always at the end of the phone or there to assist via email — there's nobody I would rather have our managed IT services with.”

“Having got by without an IT Support Provider, I had fallen into the trap of learning to live with a bad system, poor setup and dreadful security. What steered me towards Little Big Tech was the belief they would solve problems I did not even know I had — and they have. These guys may be comparatively small but the team is of the highest quality. Every communication is productive and informative.”
