Law firms sit at a unique crossroads of trust, regulation, and risk. Every day, they handle highly sensitive information that would be valuable to criminals, damaging if disclosed, and costly if lost. Information governance and security controls are therefore central to running a resilient and reputable legal practice, regardless of size.

While frameworks such as Lexcel provide useful structure, good cyber security should not be driven solely by accreditation. Done well, it supports client confidence, protects professional reputation, and reduces operational disruption. This wider view is reflected in Law Society guidance, which encourages firms to adopt recognised standards such as Cyber Essentials and ISO 27001 as part of normal business management.

Information governance as a business discipline

Information governance is often mistaken for paperwork created purely for compliance. In practice, it is about control and clarity. A well governed firm understands what information it holds, where it is stored, who can access it, and how long it should be retained.

For legal practices, this covers client files, emails, financial records, and case management data. Clear governance supports confidentiality, simplifies data protection obligations, and helps staff work consistently without relying on informal knowledge or memory. Over time, this reduces errors, improves efficiency, and strengthens resilience.

Cyber Essentials as a sensible starting point

The Law Society recommends Cyber Essentials because it addresses the most common cyber risks faced by legal practices. These risks include weak passwords, unpatched systems, basic malware attacks, and poorly protected networks.

Cyber Essentials focuses on practical controls rather than abstract theory. For small to medium sized firms, it provides a clear baseline without excessive cost or complexity. It also encourages consistent configuration of systems and better control over user access, which improves day to day IT reliability as well as security.

Adding structure with ISO 27001 and LOCS:23

Some firms operate in higher risk areas or support clients who expect more formal assurance. In those situations, broader frameworks such as ISO 27001 or LOCS:23 can add value.

ISO 27001 is based on management ownership of risk. It encourages firms to identify threats, assess their potential impact, assign responsibility, and review controls over time. LOCS:23 takes a similar approach but focuses specifically on risks common in the legal sector, including supplier management and fraud, and ensuring compliance with UK GDPR and the Data Protection Act 2018.

These frameworks are not necessary for every practice, but they offer a structured way to improve maturity where the risk profile demands it.

Being ready for cyber incidents

Cyber incidents are no longer rare events. Phishing emails, system outages, and ransomware attacks affect legal practices every year. Written incident plans are important, but they are only effective if people understand them.

Cyber incident exercises allow firms to practise their response in realistic scenarios. They test decision making, communication, and escalation under pressure. These exercises also strengthen business continuity planning by ensuring that disruption to systems does not automatically result in disruption to client service.

Policies that support real work

Policies and procedures play a central role in legal practice, but poorly written documents often go unread. Effective cyber security policies are clear, relevant, and written in plain English.

Good policies explain what is expected of staff, why the rules exist, and who is responsible. They support consistent behaviour across the firm, help new starters understand expectations quickly, and provide evidence of due care if something goes wrong. Regular review is essential to keep them aligned with changing risks and technology.

Training that reduces real risk

Most security incidents start with human error rather than technical failure. This means training is one of the most effective controls available to law firms.

Good training focuses on realistic scenarios such as spotting suspicious emails, protecting information when working remotely, and handling client data securely. It avoids technical language and focuses instead on everyday decisions staff make. Over time, this builds confidence and reduces the likelihood of simple mistakes turning into serious incidents.

Building resilience, not just compliance

Strong information governance and cyber security are about resilience. They help firms protect clients, meet professional expectations, and continue operating even when things go wrong. Standards and frameworks can support this, but they should be seen as tools rather than destinations.

A balanced approach that combines proportionate technical controls, clear governance, realistic incident planning, usable policies, and meaningful training creates security that genuinely supports the business.
