Jump to:

Law firm data security is paramount because clients entrust sensitive information to lawyers. With cybercrime on the rise, law firms are prime targets, with 29% experiencing a form of security breach, according to the 2023 ABA Cybersecurity TechReport.

As lawyers adopt AI for efficiency, cybercriminals also leverage AI for more sophisticated attacks. To mitigate the risks of data breaches, legal professionals must stay updated on the latest technology trends.

In this guide, we'll cover key aspects of law firm data security in 2024, including best practices, ethical and regulatory obligations, data security laws, security best practices, and resources to enhance data security.

Law Firm Data Security 101

Let’s start with the basics of what law firms need to know in order to keep their data protected and secure:

What is a law firm’s data security risk?

Law firms face significant data security risks that extend beyond their own operations to impact clients. Hackers target law firms due to the valuable information they hold, such as trade secrets, intellectual property, personally identifiable information (PII), and confidential attorney-client-privileged data.

Despite these risks, law firms have a duty to safeguard client information. Breaches can result in compromised communications, ransomware attacks, public leaks of sensitive data, loss of trust, and legal repercussions, including malpractice allegations.

What are your ethical and regulatory obligations?

According to the American Bar Association (ABA) Rule 1.6: Confidentiality of Information, lawyers must make reasonable efforts to prevent unauthorized access or disclosure of client information. The ABA has issued several ethics opinions providing guidance on cybersecurity, emphasizing the need for lawyers to protect client data.

To comply with ABA obligations, it’s vital to implement cybersecurity measures such as a plan, secure mobile devices, and vet legal tech providers. Incorporate legal technology responsibly to enhance data protection, streamline processes, and reduce manual errors.

What are some data security laws?

Data security laws vary by location. It’s your firm’s responsibility to understand these obligations in case of a breach.

  • HIPAA mandates protecting health information, applying to law firms as business associates handling PHI.

  • GDPR, a unified EU data protection law since 2018, emphasizes enhanced personal data protection. It's relevant globally, with many states adopting similar statutes.

  • CCPA, enacted in 2018, enhances privacy for Californian residents. Proposition 24 further strengthens these protections.

  • SHIELD Act in New York requires companies to implement reasonable safeguards for residents' private information, enhancing breach notification requirements.

Is the cloud secure enough for law firms?

Cloud-based software presents a viable option for enhancing cybersecurity in law firms. Despite inherent risks like data breaches, reputable cloud service providers offer robust security measures in comparison to traditional servers. Moreover, global spending on security and risk management is on the rise, indicating a growing commitment to safeguarding digital information.

Use safe and secure legal software solutions

When using legal software, you need to review how it will protect your clients’ information (and your firm’s data) with security measures designed to help you stay safe and compliant. Check to ensure there are built-in security measures such as:

  • Role-based permissions: Visibility into sensitive case information is restricted to specific users at your firm.

  • Password policies: Password policy settings allow you to enforce strong passwords and regular password resets at your firm.

  • Session/Activity tracking: Logging the IP address of every login to your account helps you keep an eye out for suspicious account activity.

  • Two-factor authentication: Enhance login security by verifying user identities via their mobile device.

  • Login safeguards: Will it lock your account for some time after too many failed login attempts? Using a secure client portal also keeps communications encrypted and secure.
