Law Firm Implements Zero Trust Security
The Challenge
Harrison & Associates, a 200-attorney litigation firm, discovered their security shortcomings the hard way. A sophisticated spear-phishing attack compromised a partner's credentials, giving attackers access to case files for three major corporate clients-including pending M&A documentation.
The breach required notification to affected clients and triggered security audits from two Fortune 500 clients threatening to terminate relationships. The firm's reputation, built over 40 years, was at stake.
Their existing security-perimeter firewall, basic antivirus, and password-only authentication-was clearly inadequate for modern threats. The firm needed a complete security transformation while maintaining the 24/7 availability attorneys demanded.
