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.
The UK legal sector comprises over 10,000 law firms employing more than 370,000 people, and it contributes approximately £60 billion annually to the British economy. Despite this economic significance, a concerning number of firms — particularly small and medium-sized practices — remain inadequately protected against increasingly sophisticated cyber threats. The Solicitors Regulation Authority has repeatedly warned that cyber attacks on law firms are growing in both frequency and severity, with criminals specifically targeting the legal sector because of the combination of high-value data, large financial transactions, and the trust placed in solicitors by their clients. In this environment, Cyber Essentials Plus is not merely a badge to display on your website; it is a fundamental risk management measure that every responsible firm should adopt.
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
The scale of the problem should not be underestimated. According to recent data from the SRA and the National Cyber Security Centre (NCSC), the legal sector is one of the top five most targeted industries in the UK. Criminals have become adept at exploiting the specific workflows of law firms — for example, monitoring email chains related to property transactions and then impersonating a solicitor at the critical moment of funds transfer. The consequences of a successful attack extend far beyond immediate financial loss: firms face regulatory investigation, reputational damage, loss of client confidence, potential negligence claims, and in the most severe cases, intervention by the SRA resulting in the firm's closure.
Types of Cyber Attacks Targeting UK Law Firms
Understanding the threat landscape is essential for prioritising your security investment. The following chart illustrates the most common types of cyber attacks directed at UK legal practices, based on aggregated incident data from the NCSC and SRA reports.
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.
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 regulatory environment is tightening. In recent years the SRA has published multiple thematic reviews and warning notices about cyber security in law firms, and it has taken enforcement action against firms that failed to protect client data adequately. The ICO has similarly increased its scrutiny of the legal sector, issuing reprimands and fines to firms that experienced data breaches where basic security controls were found wanting. For law firm partners and compliance officers, the message is clear: demonstrating proactive investment in cyber security — and Cyber Essentials Plus is the most recognised way to do so — is no longer optional. It is a regulatory expectation that will only grow stronger in the years ahead.
The Five Controls Applied to Legal Practice
Each of the five Cyber Essentials Plus technical controls has particular relevance to law firm operations:
Before your CE+ assessment, conduct an internal audit of admin accounts across all devices and systems. In our experience certifying law firms, the single most common finding that delays certification is partners and senior staff retaining unnecessary administrator privileges. Create a clear policy that all users — regardless of seniority — operate with standard user accounts for day-to-day work, with a separate admin account available only when genuinely required.
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.
The mechanics of a typical conveyancing fraud attack are alarmingly effective. Criminals gain access to a solicitor's email account — often through a phishing email or compromised password — and silently monitor correspondence related to property transactions. At the point when completion funds are about to be transferred, they send an email (from the genuine solicitor's account or a convincing spoof) instructing the buyer or the other side's solicitor to send funds to a different bank account. By the time the fraud is discovered, the money has typically been moved through multiple accounts and is irrecoverable. The SRA has reported individual conveyancing fraud losses exceeding £1 million, and the total cost to the UK legal sector runs into tens of millions of pounds each year. Implementing the Cyber Essentials Plus controls — particularly multi-factor authentication, secure email configuration, and endpoint malware protection — dramatically reduces the likelihood of this devastating type of attack succeeding against your firm.
For conveyancing teams, implement a verbal verification policy for all bank account details. Before any funds transfer, confirm the account details by telephone using a known number — never a number provided in the email chain. This simple operational control, combined with the technical controls of CE+, provides a robust defence against payment diversion fraud. Additionally, ensure your firm's email domain has DMARC set to reject to prevent criminals from spoofing your firm's email address when targeting your clients.
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.
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.

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.
In our experience working with London and South East law firms, we have seen CE+ certification directly lead to firms securing places on corporate legal panels that were previously closed to them. Major banks, insurers, and FTSE 250 companies now routinely include cyber security questions in their legal panel reviews, and a CE+ certificate provides a straightforward, verifiable answer. For smaller firms competing against larger practices, CE+ can be a genuine differentiator — demonstrating that the firm takes information security as seriously as its bigger competitors, despite having a smaller IT budget.
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.
Law Firm Cyber Readiness Scorecard
The following scorecard reflects the typical cyber readiness of UK law firms prior to beginning the Cyber Essentials Plus process. These scores are based on our experience conducting gap assessments for legal practices of all sizes. Areas with lower scores represent the most common remediation requirements.
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 distinction between basic Cyber Essentials and Cyber Essentials Plus is critical. Basic Cyber Essentials is a self-assessment questionnaire — you answer questions about your security controls and a certifying body reviews your answers. Cyber Essentials Plus, by contrast, includes independent hands-on testing of your actual systems. A qualified assessor will attempt to verify that your firewalls are correctly configured, test that your devices are properly patched, verify that user access controls work as intended, and scan for vulnerabilities. This independent verification is what makes CE+ significantly more credible and valuable than the basic certification. For law firms, the difference matters enormously — regulators, clients, and insurers place far greater weight on the Plus version because it provides genuine evidence of security rather than a self-declaration.
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
For firms with a predominantly cloud-based infrastructure — using platforms such as Microsoft 365, cloud-hosted case management, and company-managed laptops — the path to certification is typically straightforward. The most significant remediation work usually involves removing unnecessary admin rights, enabling MFA across all cloud platforms, ensuring all devices have up-to-date software and active firewalls, and standardising the configuration of endpoints. For firms with legacy on-premises servers, older practice management software, or a mix of personal and company devices, the remediation phase may take longer. In all cases, our approach is to implement changes incrementally and with clear communication to all staff, so that the process enhances your firm's security without disrupting client service delivery.
Start your CE+ journey by auditing your device inventory. Create a complete list of every laptop, desktop, tablet, and mobile phone that accesses firm data — including partners' personal devices. Every device in scope must meet CE+ requirements, and we frequently find that firms have forgotten about devices that are still connected to email or case management systems. A complete inventory at the outset prevents surprises during the formal assessment and ensures nothing falls through the gaps.
Cost Considerations
For law firms, the cost of Cyber Essentials Plus certification is modest compared to the risks it mitigates:
When viewed in context, the investment in CE+ certification is one of the most cost-effective risk management measures a law firm can make. Consider that the average cost of a successful cyber attack on a UK SME is estimated at between £8,000 and £25,000, but for law firms the figures are often significantly higher because of the value of the data involved and the regulatory consequences that follow. A single conveyancing fraud incident can wipe out years of profit for a small practice. Against this backdrop, an investment of £2,000 to £5,000 for comprehensive CE+ certification — which includes gap assessment, remediation support, and the formal assessment — represents an excellent return on investment. Moreover, many firms recoup this cost through reduced cyber insurance premiums within the first year of certification.
