Law firms store a variety of sensitive data and client information in their digital systems. With so much confidential information on the line, your law firm needs a sophisticated cybersecurity strategy to prevent data breaches and cyber attacks.

Implementing advanced cybersecurity measures is particularly important as many law firms switch from paper documents to digital systems. Roughly 4 in 10 law firms experienced security breaches in 2023. Even a small data breach could result in significant financial losses and damage to your firm’s reputation.

We’ve created a complete cybersecurity checklist for law firms to help you stay one step ahead of the latest digital threats. Here’s everything you need to do to keep your systems safe.


Key Takeaways

  • Law firms need to be proactive in preventing cyber attacks, data breaches, and other security issues.
  • Fully-updated systems with advanced IT infrastructure can help you keep your client data safe.
  • Compliance is particularly important for law firms, as they work with protected client data and are subject to extensive data protection regulations.
  • Your entire team can benefit from basic cybersecurity training and being involved in your emergency response plan.



1. Conduct a Cybersecurity Risk Assessment


Schedule regular assessments to identify vulnerabilities.

Potential threats can crop up in your systems without anyone realizing, leaving you exposed. Conduct an assessment of your entire system on, at minimum, an annual basis. This way, you ensure that no security issue goes unaddressed.


Engage with IT professionals for a thorough audit.

IT and cybersecurity experts will help you identify security issues in your system that you wouldn’t be able to find on your own. They can also recommend new security tools or strategies to better protect your systems.


2. Employee Cybersecurity Training


Implement ongoing training programs on cybersecurity best practices.

New cybersecurity threats emerge frequently. Conducting regular training sessions with your entire team will get everyone up to speed. This training should be available to everyone on your team, regardless of their role.


Focus on common threats such as phishing and social engineering.

Phishing and social engineering happens when hackers pose as a trusted contact in order to access sensitive information or breach your systems. 

8% of legal professionals failed phishing tests in 2023. Train your team to avoid phishing and social engineering attacks with interactive practice activities and tests.


Enforce strong password policies and use of a management tool.

Strong passwords are a key part of data security. Require your team to create complex passwords using a password management tool. 

You can also add multi-factor authentication to your systems for an extra layer of protection.


3. Protect Client Data and Communications


Use end-to-end encryption for data at rest and in transit.

Encryption uses complex cryptography to scramble your data so third parties can’t access it. 

Implement encryption solutions for your data storage systems and your emails to keep cybercriminals out. This is a must for both compliance and building trust with clients.


Establish strict access controls and authentication procedures.

Access to client information should be limited strictly to the lawyers and team members working on their cases. 

Implement a strict authentication system for employees to ensure they can only access the information they need for their roles. This can help prevent accidental data breaches and help you maintain compliance.


Ensure all client communications are conducted over secure channels.

All law firms must maintain attorney-client privilege and comply with strict data privacy laws. 

Client communication should be handled through secure online tools designed specifically for the legal industry, rather than sending unencrypted emails or text messages.


4. Maintain and Update IT Infrastructure


Regularly update software and systems to patch vulnerabilities.

Developers frequently release updates for both software and hardware products to address newly-discovered vulnerabilities and functional issues. 

Make sure to schedule regular updates for your IT infrastructure to ensure you’re not leaving data unprotected.


Deploy firewalls, antivirus software, and intrusion detection systems.

Each of these tools adds an extra layer of security to your system, and they should be deployed consistently across your systems for protection. 

These tools prevent hackers from using malware or gaining unauthorized access to your systems. They also help you respond faster in an emergency to mitigate damage to your systems.


Implement policies for secure use of mobile devices.

As remote and hybrid work models become more common in the legal field, your team may rely on laptops and smartphones to handle work tasks on the go. 

Implement a secure policy specifying when employees can and cannot use these devices. This policy should also clarify what types of Wi-Fi networks are safe to use for remote work.


5. Develop and Test an Incident Response Plan


Create a detailed plan outlining steps for different types of security incidents.

This plan should detail exactly how team members will secure your systems, restore compromised data, and communicate with clients during each incident. All employees should read the response plan thoroughly.


Regularly review and update the response plan.

If you implement new software programs or reconfigure your systems, make sure to update your response plan accordingly. Incidents can happen at any time, so you’ll need to make sure that you’re not left unprepared.


Conduct mock drills to test the effectiveness of the plan.

These drills will show you how fast your team responds to emergencies and how effectively they’re able to secure vulnerable data. Adjust the incident response plan after each drill for more efficiency.


6. Ensure Compliance with Legal Standards


Stay updated on relevant cybersecurity laws and regulations.

Law firms need to remain compliant with all applicable cybersecurity and privacy laws at the federal, state, and local level. Failing to comply with these standards could result in fines and legal consequences as well as damage to your firm’s reputation. 


Ensure all practices comply with data protection laws like GDPR or HIPAA.

In addition to industry-specific regulations, law firms also need to comply with broader data protection and consumer privacy laws. Even if strict data privacy laws haven’t yet been adopted in your state, consider adopting these best practices now to be prepared for future changes.


Document all compliance efforts for audit purposes.

Keep thorough documentation of your entire compliance and cybersecurity strategy. While audits are rare, it’s important to make sure you’re prepared.


7. Collaborate with Cybersecurity Experts


Consider managed security services for continuous monitoring and support.

A managed services provider can help with key IT tasks like system monitoring and providing support when challenges arise. An MSP can serve as an alternative to an in-house IT team or work with them.
