Cybersecurity Audit Best Practices for Law Firms

Articles
July 30, 2025

When working with your law firm, clients count on you to protect their legal interests, including their most sensitive personal and business information.

Unfortunately, the legal industry has become an increasingly popular target for cyberattacks. From contracts and case files to privileged communications, the data your firm handles every day is a goldmine for cybercriminals. 

One of the smartest steps you can take if you’re wondering whether your firm is doing enough to protect client data is to conduct a cybersecurity audit. The results will give you a clear picture of your current security standing, uncover hidden risks, and help ensure you stay compliant with ethical rules and privacy laws.

Let’s break down what makes a good audit, including what it should cover and how you can use it to strengthen your defenses without overwhelming your team.

Why Law Firms Are a Big Target

Why are law firms such prime targets for cybercriminals? It’s simple. Law firms have what hackers want. You work with high-value, confidential information. Whether your practice areas focus on mergers, litigation, intellectual property, or estate planning, it all entails working with sensitive data that would be disastrous in the wrong hands.

What makes firms even more vulnerable is that many don’t have full-time IT staff or even formal security protocols in place. That, combined with more people working remotely and using cloud-based tools, creates easy openings for things like:

  • Phishing emails
  • Ransomware attack
  • Insider threats
  • Compromised third-party vendors

All it takes is one click on a bad link or one misconfigured setting to create a breach.

You’re Also Required to Protect That Data

The ABA’s Model Rule 1.6 requires lawyers to make “reasonable efforts” to protect client information, so cybersecurity isn’t just a smart idea, it’s part of your professional obligation. 

Depending on where you practice and who your clients are, laws like the GDPR and CCPA may also apply. And if you’re handling healthcare data, financial records, or working across state or international lines, things can get complicated.

A solid cybersecurity audit can help keep you on the right side of ethics rules, privacy laws, and your clients’ expectations.

What a Cybersecurity Audit Should Look Like

A good audit isn’t just a technical exercise; it’s a chance to evaluate how your firm handles security across the board. Here’s how to approach it:

  1. Set Clear Goals: Start by defining why you’re doing the audit. Knowing your “why” helps shape the rest of the process. Are you trying to meet compliance requirements? Reduce risk? Check your systems after a recent update?
  2. Get the Right People Involved: You’ll want both legal and technical experts on the team. That might include your internal IT lead, your managing partner, or even an outside cybersecurity expert, especially to gain objectivity and specialized skills.
  3. Take Inventory: Create a list of where client data is stored and accessible, including: file servers, laptops, cloud drives, mobile devices, email accounts, etc. Don’t forget third-party platforms like e-discovery or billing software.

What Your Audit Should Cover

Once your plan is established, focus on these key areas:

  • Technical Assessment: Scan your systems for vulnerabilities and run penetration tests. Think of this like stress-testing your digital defenses to find the weak spots before a hacker does.
  • Policy and Process Review: Look at how your team handles passwords, document sharing, and file storage. Do you have a policy for how long you keep client data? Who has access? What happens if someone leaves the firm?
  • Access and Permissions: Review who has access to sensitive files and whether that access is appropriate. This includes looking at user roles, admin privileges, and inactive accounts that might be lingering in your system.
  • Vendor and Third-Party Risk: Your security is only as strong as the companies you work with. Evaluate the tools and vendors you use for things like document storage, e-signatures, or legal research practices to make sure they meet security standards.

Simple Security Practices That Make a Big Difference

Once the audit reveals what needs attention, here are some best practices to put in place:

  • Use multi-factor authentication for email, document tools, and remote access
  • Choose secure platforms for file sharing and email
  • Encrypt data wherever it lives: on your devices, servers, and in transit
  • Make sure systems and software are regularly updated
  • Train your team to recognize phishing scams and practice smart password habits

These steps go a long way toward reducing your risk without requiring a huge investment.

Be Ready for What-Ifs

Even the most secure systems can have bad days. That’s why it’s important to have a plan for what happens if something goes wrong.

Your incident response plan should include:

  • Who’s responsible for what
  • How you’ll communicate with clients and staff
  • How you’ll contain the breach and recover

Test this plan before you need it. A simple tabletop exercise with your legal and IT teams can help you spot gaps and build confidence in your response.

Cybersecurity Isn’t One and Done

An audit isn’t a once-a-year checkbox; it’s an ongoing effort. Make sure you create systems to support these consistent efforts:

  • Monitor your systems continuously
  • Schedule audits annually or after significant changes (like new software or a merger)
  • Track metrics like how quickly you resolve vulnerabilities
  • Keep your team involved and informed

This helps you stay ahead of threats and shows clients and regulators you’re serious about security.

FAQ

How often should a law firm conduct a cybersecurity audit?
At a minimum, conduct a full audit annually to stay ahead of emerging threats and regulatory updates. Additionally, schedule audits after major events—such as a merger, technology refresh, or significant security incident—to validate controls and ensure ongoing compliance.

What criteria determine whether to perform an internal audit or hire an external firm?
Use an internal audit when you have in-house expertise, understand your systems deeply, and seek cost efficiencies. Engage an external firm for objective validation, specialized skill sets (e.g., penetration testing), and to satisfy regulatory or client-mandated independence requirements.

Which tools and platforms are most effective for vulnerability scanning in legal environments?
Industry-leading tools like Tenable Nessus, Qualys VMDR, and Rapid7 InsightVM offer robust, authenticated scanning and detailed reporting. Choose platforms with customizable compliance templates (e.g., GDPR, CCPA) and easy integration with your SIEM or ticketing systems for streamlined remediation tracking.

How can remote or hybrid law firms ensure consistent audit coverage across all locations?
Deploy cloud-based scanning agents and centralized logging to maintain visibility wherever users connect. Standardize audit procedures—using the same toolchains, checklists, and reporting templates—and schedule regular virtual walkthroughs or periodic on-site assessments to verify consistency.

What training should staff receive to support ongoing audit and compliance efforts?
Provide mandatory security awareness training covering phishing, secure document handling, and password hygiene. Implement role-based workshops for IT and legal teams on incident response, data classification, and audit evidence collection to ensure everyone understands their responsibilities.

How do you measure the success of a cybersecurity audit beyond finding vulnerabilities?
Track key metrics such as time-to-remediation for high-risk findings, reduction in repeat vulnerabilities year-over-year, compliance score improvements, and the percentage of systems covered by automated monitoring. These indicators demonstrate real progress in strengthening your security posture.

What budget considerations should firms plan for when scheduling regular audits?
Budget for licensing or subscription fees of audit tools, potential external consultant fees, staff hours for planning and remediation, and training costs. A best practice is to allocate roughly 2–5% of your annual IT budget toward security assessments and related improvements.

How do law firms integrate audit findings into their broader risk-management framework?
Feed audit results into a centralized risk register, assign remediation tasks with clear owners and deadlines, and update your formal risk assessments. Use a GRC (Governance, Risk, and Compliance) platform or dashboard to track progress and report status to stakeholders.

Can audit results help in negotiating cyber insurance policies for law firms?
Absolutely. Demonstrating a rigorous, documented audit process and timely remediation of findings signals mature risk management, often translating to lower premiums and broader coverage. Insurers value evidence of proactive security controls when underwriting your policy.

What role does executive leadership play in driving audit recommendations to completion?
Executive sponsorship is critical: leaders must endorse the audit, allocate necessary resources, and hold teams accountable for remediation. Regularly reviewing audit dashboards at the board or partnership level ensures visibility and drives timely action on high-impact security initiatives.
