Business Email Compromise (BEC)
Email impersonation, payment diversion, invoice modification, and compromise of solicitors' or chambers' accounts.
Cyber Security for Legal & Professional Services
Protecting confidential client information, communications, and case data from targeted compromise and operational disruption.
Cyber Defence for Legal Practices
Legal firms handle some of the most sensitive client information in industry – commercial transactions, litigation files, intellectual property, M&A documents, and regulatory disclosures. Attackers know this, and increasingly target law firms to exploit email trust, steal confidential material, or extort via ransomware.
Cyber Defence protects legal practices through SOC365 monitoring, targeted Threat Intelligence, offensive testing, and rapid Incident Response. We ensure that your firm maintains confidentiality, integrity, and operational continuity in a high-stakes threat environment.
Threats
Key cyber threats facing legal practices
Law firms and professional services organisations are targeted for the sensitivity and commercial value of their data. We protect against:
Confidential document leakage
Theft of case files, M&A documentation, contracts, witness statements, or litigation strategy.
Ransomware & operational disruption
Attacks targeting case management systems, file shares, cloud drives, or remote-working systems.
Cloud & identity compromise
Exploitation of Microsoft 365 identities, weak MFA configurations, or session hijacking.
Supply chain threats
Attacks via integrated barristers' chambers, expert witnesses, outsourced IT, or legal software providers.
Impersonation and reputational attacks
Phishing and domain impersonation designed to deceive clients, partners, or internal stakeholders.
Services
How Cyber Defence supports legal firms
We provide end-to-end protection across monitoring, intelligence, testing, and response – sized and scoped for firms of all profiles, from small practices to global partnerships.
SOC365 Managed Detection & Response
24/7 monitoring for email compromise, cloud identity misuse, data exfiltration, ransomware precursors, and unauthorised access.
Threat Intelligence
Dark web monitoring for leaked case files, compromised credentials, domain impersonation, and phishing campaigns targeting legal clients.
Penetration Testing
Testing of case management systems, client portals, M365 configuration, web applications, and remote-access paths.
Incident Response & IR Retainer
Immediate assistance during ransomware, BEC, or data leakage events, with contractually guaranteed response times.
Security Engineering
Hardening of Microsoft 365, identity systems, VPN, document management systems, and remote-working endpoints.
Protecting cloud identity, IT and modern hybrid legal environments
Legal practices increasingly depend on Microsoft 365, Teams, cloud-based case management platforms, secure print systems, and remote hearing or conferencing technology. Cyber Defence ensures strong identity security, logging, access controls, and monitoring across these systems.
While legal firms rarely operate heavy OT environments, we consider all operational systems with cyber relevance – remote access appliances, Wi-Fi, conference systems, printers, VPN gateways, and chambers' shared resources.
