Legal Services Cybersecurity
Protect privileged client data and meet the security expectations in outside counsel guidelines and cyber insurance applications.
Privileged Data, Growing Client Expectations
Law firms hold some of the most sensitive information in any client relationship — privileged communications, deal terms, litigation strategy, and personal data — often for clients who are themselves high-value targets. That makes firms an attractive path of least resistance for attackers.
Corporate clients have taken notice. Outside counsel guidelines and cyber insurance applications increasingly demand specific, demonstrable security controls — not just an assurance that "we take security seriously." We help firms build a program that actually satisfies both.
Why Legal Services Is a Target
- Privileged and confidential data with high resale value
- Access to sensitive information about high-value clients
- Security teams typically thinner than client expectations
- Wire transfers for real estate, M&A, and trust accounts
- Growing outside counsel guideline and insurer requirements
- Reputational damage from a breach is disproportionately severe
Risks Specific to Legal Services
The threats that consistently show up in our law firm and legal services engagements.
Attackers increasingly exfiltrate privileged documents before encrypting systems, using the threat of disclosure — not just downtime — as leverage.
Real estate closings, settlement disbursements, and trust account transfers routed through email are prime targets for business email compromise.
Corporate clients increasingly require documented security controls as a condition of engagement — and cyber insurers ask similar questions at renewal.
Matter-based access controls, conflict walls, and least-privilege document management are both an ethical obligation and a security control.
Document review platforms, court filing systems, and co-counsel relationships all extend the boundary of what "your" security posture actually covers.
Attorney and staff inboxes are a direct line to privileged communications, making account takeover both a security incident and a confidentiality breach.

Frequently Asked Questions
Our corporate clients require an outside counsel security questionnaire. Can you help us respond?
Yes. We regularly help firms assess their actual posture against outside counsel guidelines and cyber insurance applications, close the gaps that matter, and respond to the questionnaire with confidence instead of guesswork.
Is a law firm really a likely ransomware target?
Very much so. Firms hold privileged, high-value client information and often have thinner security teams than the corporate clients they represent — making them an efficient route to sensitive data attackers can't get directly.
We're a small or mid-size firm. What's a reasonable place to start?
Most firms start with a focused audit against a recognized framework, paired with email security hardening given how much firm business runs through inbox-based trust wire and document transfers.
