The role of legal counsel in cybersecurity has shifted. In 2025, large law firms are no longer bystanders in cyber governance — they’re front-line leaders.
From mergers and acquisitions to compliance reviews and supplier agreements, legal teams are taking a more active role in cyber due diligence. Why? Because clients, regulators, and insurers demand it — and law firms themselves are under growing threat.
Why Cyber Is Now a Legal Concern
The legal profession handles a goldmine of sensitive information:
📁 M&A term sheets
📄 HR disputes and payroll data
📨 Board minutes and internal comms
🧑⚖️ Case files under NDA
Any breach risks more than a headline — it risks regulatory penalties, broken trust, and reputational damage that can take years to recover from.
This has prompted large law firms to build out cybersecurity and risk teams internally, often embedded within general counsel, compliance, or GRC departments.
Due Diligence Is Not Just for Clients
Firms are applying due diligence frameworks to themselves. That means:
🔍 Scanning and monitoring their own digital estate — not just trusting IT to “have it covered”
🔗 Assessing risk in legal technology platforms — including case management, e-discovery, and document sharing tools
📋 Auditing third-party access — especially vendors involved in client matters, litigation support, and remote processing
💼 Scrutinising cyber insurance policies — to ensure breach response, legal liability, and business interruption are adequately covered
Large firms are also building cyber health checks into their own client services — providing risk evaluations as part of M&A, commercial contract, and regulatory compliance engagements.
