Managed security & breach readiness for law firms

Protect client confidentiality with security that is exercised, evidenced and monitored continuously. Claranet combines CREST-accredited offensive security, managed compliance and 24/7 detection and response to help legal teams prepare for the breach they hope never happens.

Test your breach readiness

A defensible legal security posture needs more than policies on paper: test the controls, operate the management system and monitor the estate around the clock.

Know how your firm will respond before an attacker finds out

Law firms concentrate commercially sensitive data, privileged communications and high-value transaction information. Breach readiness therefore depends on people, process and technology working together under pressure.

Claranet can assess that complete operating picture. Our offensive-security teams test how an attacker could enter and move through the estate, while red and purple-team exercises show whether detection, escalation and incident-response processes work in practice. Findings are turned into an improvement backlog rather than a one-off report.

Alongside testing, we can support the management systems that hold the programme together: ISO 27001 for information security, ISO 42001 for AI management, and Cyber Essentials / Cyber Essentials Plus where appropriate. The aim is to keep evidence, risk registers, controls and audit activity current throughout the year.

For continuous defence, Claranet can right-size a managed SOC and MDR service around your existing environment, including Microsoft security tooling where appropriate. That gives the firm 24/7 detection, investigation and response capacity without trying to build every capability internally.

Simulate the breach, including the latest attacker TTPs

A tabletop exercise can prove that a plan exists. A red or purple-team engagement tests whether the organisation can actually detect and respond when realistic attacker behaviour is present.

Our CREST-accredited testers can emulate current tactics, techniques and procedures across identity, endpoints, cloud, applications and user behaviour. Purple-team activity then works directly with defenders to validate telemetry, controls and response paths.

  • Threat-led scenarios aligned to your risk profile and critical client services.
  • MITRE ATT&CK-informed attack paths and realistic adversary behaviour.
  • Validation of detection, escalation, containment and executive decision-making.
  • Clear remediation roadmap with retesting to prove improvements worked.

Scope a breach-readiness exercise

Keep ISO 27001, ISO 42001 and Cyber Essentials under control

Compliance should be a living management system, not an annual scramble before the audit. Claranet can provide ongoing governance support to keep controls, evidence, risks and improvement actions current throughout the year.

For ISO 27001 we support the ISMS. For ISO 42001 we support the AI management system. Cyber Essentials and Cyber Essentials Plus can sit alongside those frameworks as a practical baseline for technical controls and supply-chain assurance.

  • Gap assessments, control mapping, evidence collection and remediation tracking.
  • Ongoing policy, risk-register, Statement of Applicability and audit-readiness support.
  • AI governance aligned to ISO 42001 without incorrectly treating it as an ISMS standard.
  • Forward view of changing requirements so remediation can be planned before renewal or audit windows.

Review your compliance operating model

Right-size a 24/7 SOC around the firm you actually run

More tooling does not automatically create better detection. We assess your estate, telemetry, Microsoft investment and internal capability, then design a managed detection and response model around the coverage you need.

Claranet’s managed SOC provides continuous monitoring, investigation and threat hunting, with response processes designed to reduce the time between suspicious activity and containment. This can support the supplier-assurance expectations increasingly placed on law firms by large clients and procurement teams.

  • 24/7/365 monitoring and response across users, endpoints, cloud and infrastructure.
  • Support for Microsoft Sentinel and Defender, or integration with the security stack already in place.
  • Proactive threat hunting and continuous tuning to improve signal quality.
  • Management reporting and evidence suitable for security governance and client assurance conversations.

Would your controls hold up during a real breach?

We can combine red-team testing, compliance operations and 24/7 managed detection into one improvement programme focused on the systems and client data that matter most.

Legal technology FAQs

  • A penetration test normally assesses defined systems for exploitable weaknesses. A red-team exercise is broader and objective-led: it simulates an adversary attempting to reach a target while testing detection, response and organisational controls.

  • Purple teaming brings attackers and defenders together. The offensive team demonstrates techniques while the defensive team validates logging, detections, triage and response, allowing gaps to be fixed during the exercise.

  • The proposed managed-compliance model can support the ongoing operation of the ISMS: evidence, control reviews, risk and action tracking, audit preparation and continuous improvement, subject to final service scope.

  • No. ISO/IEC 42001 is an AI management system standard. ISO/IEC 27001 is the information security management system standard. A legal firm may operate both as complementary governance frameworks.

  • Yes. Claranet offers managed detection and response with Microsoft Sentinel and Microsoft Defender, including continuous monitoring, threat hunting and response.

  • Threats do not operate to office hours. Continuous monitoring reduces the risk that malicious activity sits undetected overnight or through weekends and can strengthen the evidence available for client and supply-chain assurance.
