29% of law firms experienced a security breach in 2023, according to the ABA Cybersecurity TechReport. As someone who has spent years helping organizations navigate cybersecurity challenges, I've seen firsthand how devastating these breaches can be, not just financially, but in terms of client trust and professional reputation.
Unfortunately, far too often, people like me get called in only after something has gone terribly wrong. So I wanted to write this blog to help decision-makers understand that cybersecurity should be a business imperative — not an afterthought.
Why Cybersecurity for Law Firms Is Non-Negotiable
When we talk about cybersecurity for law firms, we're not just discussing IT best practices. We're talking about professional survival. A single data breach can result in:
- Malpractice lawsuits from affected clients
- Regulatory fines under GDPR, CCPA, HIPAA, or state laws
- Loss of client trust and referrals
- Business disruption from ransomware attacks
- Professional sanctions from state bar associations
The American Bar Association's Rule 1.6 clearly states that lawyers must make "reasonable efforts" to prevent unauthorized access to client information. But what constitutes "reasonable" in 2025 looks a lot different than it did just five or six years ago.
The Current State of Law Firm Cybersecurity Compliance in 2025 and Beyond
Cybersecurity isn't just about following ABA guidelines. Depending on your practice areas and client base, you may need to comply with multiple regulations:
GDPR (General Data Protection Regulation)
If you handle data from EU residents, GDPR applies regardless of where your firm is located. The regulation requires explicit consent for data processing and mandates breach notification within 72 hours.
HIPAA (Health Insurance Portability and Accountability Act)
Law firms handling protected health information (PHI) must comply with HIPAA's security requirements, including encryption, access controls, and audit logs.
State-Specific Laws
Depending on where you’re located, you may have additional requirements for maintaining privacy or how you respond to a cybersecurity incident:
- California's CCPA enhances privacy rights for California residents
- New York's SHIELD Act requires reasonable safeguards for personal information
- Various state breach notification laws mandate specific response timelines
The key is understanding which regulations apply to your specific practice and implementing controls accordingly.
Effective Cybersecurity Management Strategies for Law Firms
Every law firm requires a clear strategy for making and evaluating cybersecurity. There are a number of tools and providers that can help you protect your clients, your systems, and your data. But these are the most important areas to have covered, in some form or another:
1. Governance and Risk Assessment
Start with understanding what data you have, where it's stored, and who has access. Conduct regular risk assessments to identify vulnerabilities and prioritize remediation efforts.
2. Technical Safeguards
Implement multi-layered security controls:
- Firewalls to control network traffic
- Encryption for data at rest and in transit
- Endpoint protection on all devices
- Email security to prevent phishing attacks
- Backup and recovery systems for business continuity
3. Access Controls
Not everyone in your firm needs access to everything! Implement role-based permissions and the principle of least privilege. Use multifactor authentication (MFA) for all systems containing sensitive data.
4. Security Awareness Training
Your employees are both your greatest asset and your biggest vulnerability. Regular training should cover:
- Recognizing phishing attempts
- Creating strong, unique passwords
- Secure handling of client data
- Incident reporting procedures
I should mention that by regular training, I don’t mean passing out the same old handout every six months. I’m talking about providing relevant, engaging training that gets people talking, allows them to practice their skills, lets you see how effective your training actually is, and helps your staff understand how important their role is.
I’m talking about training that’s so effective that you start seeing an overabundance of caution, and that caution is rewarded, from the top all the way down.
The Need for Ongoing Cybersecurity Management
The protections I outlined above aren’t enough to stop every single cybersecurity attack imaginable, but they are enough to encourage the typical cybercriminal to shift to an easier target. And unfortunately, there are still plenty of them.
Plus, if every organization had these basics in place, it would be much harder for cybercriminals to make money so quickly and with so little risk. And considering that most of them are simply looking for a quick payout, I believe that many of them would take up a different line of work.
In our world, we say that business technology changes by the year, but cybersecurity changes by the month, and sometimes by the day. Therefore, effective cybersecurity management goes beyond installing a set of software or writing up a set of rules.
It requires ongoing attention to:
- How your industry is being targeted
- How attackers are adjusting their tactics
- How your organization should respond to a cyberattack
- What your employees are responsible for
- Who has access to your systems and data (including vendors)
I should mention that my colleague, Glenn Sweeney, did a deeper dive on the importance of vendor due diligence and other recommendations for law firms in a recent Q&A.
Practical Steps To Get Started
If your firm hasn’t updated its cybersecurity posture in five years, it’s time.
I often hear from law firm partners that cybersecurity is too expensive. While the typical data breach in 2025 is far more expensive ($10.22M in the US), there’s an even more important point to be made, which is that nowadays, having effective cybersecurity isn’t just what’s expected — it could help you win more business.
