# 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.

## Key takeaways

- Phishing and credential theft remain the usual entry routes; train for them.
- Fund the basics first: authentication, updates, backups, training.
- Treat vendors and AI tools as part of your attack surface.
- Have an incident plan before you need one, including regulator and client notification duties.

## Priorities for a small firm

| Priority | Control | Effort |
| --- | --- | --- |
| 1 | Multi-factor authentication on email, document storage and practice tools | Low |
| 2 | Password manager and unique passwords | Low |
| 3 | Automatic updates and device encryption | Low |
| 4 | Phishing awareness and payment-change verification | Medium |
| 5 | Tested, separate backups | Medium |
| 6 | Vendor review and access cleanup | Medium |
| 7 | Written incident response plan | Medium |


## 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.


## A 90-day plan

1. Month 1: Turn on MFA everywhere, install a password manager, enable device encryption and updates.
2. Month 2: Audit who has access to what; remove stale accounts; set up backups and test a restore.
3. Month 3: Run a phishing exercise, adopt an AI-use policy, write the incident plan.

Track these tasks as items in a Notion database with owners and due dates. LawyerOS focuses on matters and deadlines, so create a simple Security tasks database yourself if you want one; the template does not provide security tooling or monitoring.

## FAQ

### 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.
