The 7 most common IT weak spots in law firms

Law firms handle some of the most sensitive data in the UK: client records, contracts, financial information, and confidential case details. Yet despite strict regulatory obligations, many firms still operate with significant IT vulnerabilities that leave them open to disruption, data breaches, and reputational damage.

Drawing on insights from Greg Chapman, managing director of Chapman Technology Partners, this article explores the seven most common IT weak spots found in UK law firms, and how to fix them.

1. Outdated or Unpatched Software
Many firms continue to rely on legacy systems, old versions of Windows, or unsupported case management platforms. These systems often lack critical security updates, making them easy targets for cybercriminals.

Greg Chapman, managing director at Chapman Technology Partners said: “We still see firms running outdated software simply because it ‘still works’. But unsupported systems are one of the biggest open doors for ransomware and data theft.” 

Solution: Implement a strict patch management policy and move legacy systems to supported cloud platforms such as Microsoft 365 or Azure, with centralised update control.

 2. Weak Access Controls
Password reuse, shared logins, and lack of multi-factor authentication (MFA) are still common across smaller firms. Without strong access controls, one compromised password can expose entire client databases.

Solution: Introduce Zero Trust principles - verify every access attempt, enforce MFA across all accounts, and use identity management tools like Microsoft Entra ID.

3. Lack of Employee Cyber Awareness
Phishing remains one of the top threats facing the legal sector. According to the National Cyber Security Centre (NCSC), phishing accounts for over 80 per cent of initial attack vectors in UK cyber incidents.

Solution: Run quarterly phishing simulations and training sessions to keep awareness high. Chapman Technology Partners’ Cyber Awareness Training helps legal teams recognise and respond to phishing attempts before damage is done.

4. Poor Data Backup and Recovery Plans
Many firms still rely on local backups or USB drives that aren’t tested regularly. Without a tested disaster recovery plan, a ransomware attack could halt operations for days, or longer.

Solution: Adopt automated cloud backups stored in UK data centres, with clearly defined Recovery Time Objectives (RTOs) and Recovery Point Objectives (RPOs). Test restoration processes quarterly to ensure data integrity.

5. Unsecured Remote Work Practices
Since hybrid work became common, unsecured home networks, personal devices, and weak VPN setups have become prime attack vectors.

Solution: Use a Managed IT and Security Service to enforce secure endpoint protection, encrypted connections, and device management policies across all user devices.

6. Insufficient Compliance and Audit Readiness
Law firms must comply with the SRA Code of Conduct, GDPR, and (if they handle financial transactions) certain FCA requirements. Yet many firms struggle to demonstrate audit readiness or track data flow.

Solution: Implement compliance-aligned IT policies, data retention schedules, and audit logging tools that align with UK regulatory frameworks. Chapman Technology Partners helps firms achieve this through structured compliance roadmaps.

7. Overlooked Endpoint Security
Every laptop, smartphone, or tablet is a potential entry point. Without proper endpoint detection and response (EDR) systems, firms often miss the early warning signs of a breach.

Solution: Deploy EDR and AI-driven threat detection that continuously monitors for suspicious activity. Centralised management ensures threats are contained before they spread.

Strengthening Your Firm’s IT Foundation
Each of these weak spots represents a serious risk—but they are all preventable. With the right IT partner, law firms can move from reactive to cyber-resilient, ensuring business continuity and client trust.

“Modern law firms must think of cybersecurity as a core part of client service,” says Greg Chapman. “Protecting client data isn’t just about compliance - it’s about maintaining credibility.”
