Law firms are among the most targeted organisations in the United Kingdom when it comes to cyber attacks. Solicitors and barristers handle some of the most sensitive information imaginable — from confidential client communications and financial records to intellectual property and evidence in criminal proceedings. This makes legal practices an exceptionally attractive target for cyber criminals, and it is why Cyber Essentials Plus certification is increasingly essential for law firms of all sizes.

This guide explores why law firms need Cyber Essentials Plus, how the certification addresses the specific security challenges of legal practice, and what the path to certification looks like for a typical firm.

Why Law Firms Are Prime Targets

Cyber criminals target law firms for several compelling reasons:

High-value data: Client files contain financial details, personal information, trade secrets, and legally privileged communications
Financial transactions: Conveyancing firms in particular handle large sums of money, making them targets for payment diversion fraud
Trust relationships: Clients trust their solicitors implicitly, making phishing attacks that impersonate law firms highly effective
Time pressure: Legal deadlines create urgency that can lead to rushed security decisions
Smaller firms, smaller budgets: Many legal practices are SMEs without dedicated IT security teams

Regulatory Pressure on Law Firms

The Solicitors Regulation Authority (SRA) has made it clear that cyber security is a regulatory priority. Law firms have a professional obligation to protect client data, and the SRA actively monitors and investigates firms that suffer data breaches.

SRA Position: The SRA expects law firms to have appropriate cyber security measures in place and to be able to demonstrate what steps they have taken to protect client information. While the SRA does not mandate Cyber Essentials Plus specifically, holding the certification provides strong evidence of compliance with SRA expectations around information security.

Beyond the SRA, law firms also face requirements from:

The Information Commissioner's Office (ICO) under GDPR and the Data Protection Act 2018
The Law Society, which recommends Cyber Essentials as a minimum standard
Client procurement requirements — corporate and government clients increasingly require their legal advisors to hold CE+ certification
Professional indemnity insurers who may require or incentivise cyber security certification
The Legal Aid Agency, which requires Cyber Essentials for firms providing legal aid services

The Five Controls Applied to Legal Practice

Each of the five Cyber Essentials Plus technical controls has particular relevance to law firm operations:

Control	Law Firm Application	Common Issues
Firewalls	Protecting case management systems and client portals	Remote workers bypassing office firewall
Secure Configuration	Hardening devices used by solicitors and support staff	Partners with admin rights on their devices
User Access Control	Matter-level access restrictions, MFA on legal platforms	Shared accounts for case management systems
Malware Protection	Protecting against ransomware that could encrypt client files	Fee earners opening malicious email attachments
Patch Management	Keeping case management, billing, and office software updated	Legacy practice management software

Specific Challenges for Law Firms

Email Security and Conveyancing Fraud

Email is the lifeblood of legal practice, and it is also the primary attack vector. Conveyancing fraud — where criminals intercept email communications to divert property transaction funds — has caused devastating losses for UK law firms and their clients.

While Cyber Essentials Plus does not directly address email content, the controls around secure configuration, user access, and malware protection significantly reduce the risk of email-based attacks. Combined with proper email security measures (SPF, DKIM, DMARC), CE+ certification forms a strong foundation for email protection.

Legal Professional Privilege

Law firms have a legal and ethical obligation to protect legally privileged communications. A data breach that exposes privileged material can have severe consequences — not just regulatory penalties, but potential damage to client cases and the firm's professional standing.

Key Point: Cyber Essentials Plus provides an independently verified baseline of technical security that supports your firm's duty to protect privileged and confidential information. It demonstrates to clients, regulators, and insurers that you have taken concrete, verified steps to secure their data.

Case Management Systems

Most law firms rely on specialist case management software (such as LEAP, Clio, PracticePanther, or Proclaim). These systems are in scope for CE+ if they are cloud-hosted or accessible over the internet. Key requirements include:

MFA enabled for all users
Role-based access controls properly configured
The platform must be kept up to date with security patches
Admin accounts must be separate from standard user accounts

The Partnership Structure Challenge

Law firm partnership structures can create unique challenges for CE+ compliance. Partners sometimes expect elevated IT privileges, unrestricted access to systems, or the ability to use personal devices without management controls. CE+ requires that all users — including senior partners — follow the same security controls.

Common Law Firm Failures

Partners refusing to enable MFA
Shared login credentials for practice management
Admin rights granted to fee earners
Unpatched legacy case management software
Personal devices used without MDM controls
No firewall on home-working devices

What Certified Firms Get Right

MFA enforced for all staff including partners
Individual accounts with unique credentials
Standard user accounts for daily work
All software on supported, patched versions
Company-managed devices or MDM-enrolled
Software firewalls on every device

The Business Case for Law Firms

Beyond regulatory compliance, Cyber Essentials Plus offers tangible business benefits for law firms:

Winning Work from Corporate Clients

Corporate clients, particularly in regulated sectors (financial services, healthcare, government), increasingly require their legal advisors to demonstrate cyber security credentials. CE+ certification can be the deciding factor in legal panel appointments and tender processes.

Cyber Insurance Benefits

Professional indemnity and cyber insurance providers view CE+ favourably. Certified firms may benefit from lower premiums, broader coverage, and fewer exclusions. Some insurers now require CE+ as a condition of coverage.

SRA Risk Assessment

The SRA conducts risk-based supervision and considers cyber security as a key risk factor. Firms that can demonstrate CE+ certification are better positioned when the SRA assesses their risk profile.

92%

of corporate legal departments consider supplier cyber security when appointing external counsel

The Legal Aid Agency Requirement

For law firms providing legal aid services, Cyber Essentials certification is already a contractual requirement from the Legal Aid Agency (LAA). This applies to all firms with a legal aid contract, regardless of size. Many firms start with basic Cyber Essentials and then progress to CE+ for the additional assurance of independent verification.

The Certification Process for Law Firms

At Cloudswitched, we have extensive experience certifying law firms of all sizes. Our process is designed to minimise disruption to fee-earning work:

Gap Assessment (Day 1–3): We review your current IT environment, case management systems, email configuration, and devices against CE+ requirements
Remediation Plan (Day 3–5): We provide a clear, prioritised list of changes needed, with estimated timelines for each
Implementation (Week 1–3): We carry out the remediation work — enabling MFA, configuring firewalls, removing admin rights, updating software — with minimal impact on daily operations
Pre-Assessment Verification (Week 3–4): We conduct our own internal assessment to ensure everything is ready
Formal Assessment (Week 4–6): The accredited certification body conducts the official CE+ assessment
Ongoing Support: We maintain your compliance throughout the year and handle annual renewal

Minimal Disruption: We understand that every hour of downtime costs a law firm money. Our approach is designed to implement changes outside core working hours where possible and to ensure that no security change interferes with your ability to serve clients.

Cost Considerations

For law firms, the cost of Cyber Essentials Plus certification is modest compared to the risks it mitigates:

Scenario	Typical Cost
CE+ certification (managed service)	£2,000 – £5,000
Conveyancing fraud incident	£50,000 – £1,000,000+
ICO fine for data breach	£10,000 – £17,500,000
SRA investigation and sanction	£5,000 – £500,000+
Loss of a major client due to security concerns	Incalculable
