Law firm cybersecurity essentials for 2026

Law firm cybersecurity essentials are accounts protected by multi-factor authentication, patched and encrypted devices, careful email handling, staff training, tested backups, vetted vendors and a written incident plan. For small firms, doing these basics consistently beats buying advanced tools.

Law-specific risks

  • Payment-redirection fraud: confirm any change of bank details by phone using a known number, especially in property or settlement transactions.
  • Impersonation of clients or partners by email.
  • Lost laptops and phones holding client files.
  • Departing staff with lingering access.
  • Staff pasting client details into consumer AI tools.

The ethics angle is consistent across many jurisdictions: take reasonable steps to protect client information, supervise staff and suppliers, and be ready to inform affected clients if something goes wrong. Check your own regulator for specifics.

Frequently asked questions

What is the most important control?
Multi-factor authentication on key accounts, followed closely by updates and backups.
Do small firms need cyber insurance?
Many consider it. Read the policy for conditions such as MFA requirements and notify your insurer as required.
How often should staff be trained?
On joining and at least annually, with shorter reminders about current scams.
Can Notion improve our security?
It can help you organise tasks and policies, but it is not a security tool.
