Yes. Law firms hold confidential client information, privileged communications, financial records, credentials, and case materials that can be valuable to attackers. A practical cybersecurity program should address prevention, detection, response, and governance rather than relying on a single product. Services such as managed detection and response, risk assessment, penetration testing, incident readiness, and compliance support can help firms reduce exposure and demonstrate responsible security practices.
