What Is Cyber Essentials and Do Law Firms Need It?

Cybersecurity is a growing concern for law firms, particularly as cybercriminals increasingly target organisations that handle sensitive client information. Many legal practices are now considering Cyber Essentials certification as a way to strengthen security and demonstrate good data protection practices.

Cyber Essentials is a UK government-backed cybersecurity certification scheme designed to help organisations protect themselves against common cyber threats. For most law firms, achieving Cyber Essentials typically takes 4–8 weeks and involves implementing five key security controls across systems and devices.

For firms handling confidential legal data, Cyber Essentials can provide reassurance to clients, reduce cybersecurity risk, and help demonstrate that appropriate protections are in place.

What Is Cyber Essentials?

Cyber Essentials is a cybersecurity certification programme developed by the UK government and the National Cyber Security Centre (NCSC).

The scheme focuses on protecting organisations against the most common cyber threats by ensuring essential security controls are properly implemented.

The certification confirms that an organisation has implemented key cybersecurity protections including:

• secure internet connections
• controlled access to systems
• secure device configuration
• protection against malware
• regular software updates

For many professional services organisations, Cyber Essentials is considered the baseline standard for cybersecurity hygiene.

Why Cybersecurity Is Critical for Law Firms

Most MSPs charge per user per month. The more staff members and devices that require support, the higher the overall monthly cost.

Law firms are attractive targets for cybercriminals because they store:

• confidential client communications
• sensitive legal documents
• financial transaction information
• intellectual property data

A successful cyber attack could lead to:

• data breaches
• financial fraud
• operational disruption
• reputational damage

Strong cybersecurity controls help reduce these risks and ensure client information remains protected.

Law firms implementing Cyber Essentials are often strengthening the same protections required to meet SRA expectations around information security. You can learn more in our guide on cybersecurity measures law firms need to meet SRA compliance.

The Five Security Controls Required for Cyber Essentials

Cyber Essentials focuses on five core security areas.

1. Firewalls and Secure Internet Gateways

Organisations must ensure their internet connections are protected by properly configured firewalls to prevent unauthorised access.

2. Secure Configuration

Devices and systems should be configured securely, removing unnecessary software and default settings that could create vulnerabilities.

3. User Access Control

Access to systems should be restricted so that employees only have permissions necessary for their role.

Multi-factor authentication (MFA) is typically recommended for systems such as email and cloud platforms.

4. Malware Protection

Devices should be protected by modern endpoint security solutions that detect and block malware and ransomware attacks.

5. Security Updates

Software and operating systems must be kept up to date with security patches to prevent attackers exploiting known vulnerabilities.

How Long Does Cyber Essentials Certification Take?

For most small and mid-sized organisations, Cyber Essentials certification can be achieved relatively quickly.

Typical timeline:

Step	Time
Initial security review	1–2 weeks
Implement required protections	2–4 weeks
Complete certification assessment	1–2 weeks

For many law firms, much of the required security infrastructure is already in place through managed IT services and cybersecurity tools.

Cyber Essentials vs Cyber Essentials Plus

There are two levels of certification.

Cyber Essentials

This involves completing a self-assessment questionnaire that verifies security controls are implemented.

Cyber Essentials Plus

Cyber Essentials Plus includes independent technical testing to confirm systems are secure.

This involves vulnerability testing and verification of security protections.

Many organisations start with Cyber Essentials and later progress to Cyber Essentials Plus.

How Cyber Essentials Fits Into a Law Firm’s IT Strategy

Cyber Essentials should not be viewed as a one-time certification. Instead, it forms part of a broader technology and security strategy.

For example, many law firms combine Cyber Essentials with:

• managed IT services
• secure Microsoft 365 environments
• endpoint protection and monitoring
• secure backup and disaster recovery
• regular IT security reviews

To understand how these services are typically packaged and priced, see our guide on how much managed IT services cost for law firms in London.

Example: Achieving Cyber Essentials for a London Law Firm

A 40-person law firm in London recently worked to improve its cybersecurity posture ahead of applying for Cyber Essentials certification.

The firm implemented several improvements including:

• multi-factor authentication for Microsoft 365
• advanced endpoint security protection
• secure cloud backup systems
• staff cybersecurity awareness training

Following these changes, the firm successfully achieved Cyber Essentials certification, helping reassure clients that appropriate security measures were in place.
