Contain an attack in seconds, so deadlines and client matters stay on track.
Law firm ransomware puts more than systems at risk. Privileged documents, client files and court and transaction deadlines all depend on the same servers and document stores. Helm contains ransomware at the data layer, so client work can keep moving and you have a clear record to show clients how an attack was handled.
Law, accounting and consulting firms hold some of the most valuable information their clients have, from litigation files to deal documents and financial records. Their work runs on billable hours and fixed deadlines, so downtime has a clear and immediate cost.
Attackers know this. BakerHostetler, which advises organisations on incident response, responded to nearly twice as many law-firm incidents in 2025 as in 2024, when it handled more than 30.
When a large Australian law firm was hit in 2023, the attackers published stolen data belonging to its clients. For a professional services firm, the impact reaches clients, not only IT.

Answers ready for client security questionnaires.
Most professional services firms have no dedicated cyber regulator. The duty comes from confidentiality. In the US, ABA Model Rule 1.6 asks lawyers to make reasonable efforts to prevent unauthorised access to client information. In the UK, the SRA expects firms to keep client information confidential, and under GDPR a personal data breach must be reported within 72 hours.
The sharpest questions often come from clients, through security questionnaires and panel reviews. How would you contain an attack, how fast would you recover, and how would you show what happened?
Helm supports the answers. Every detection and containment step is recorded with a timestamp and mapped to frameworks such as GDPR, NIST CSF and CIS18, ready for client reviews, your insurer and your own risk committee.
Helm protects the file servers and document stores where client matters live, on site and in Microsoft 365, with nothing installed on lawyers’ or consultants’ laptops, whether your IT is run in-house or by a managed service provider.
When encryption starts, Helm detects it in under a second and responds on fixed, readable rules your team sets, with no AI involved. It isolates the compromised accounts and devices, while the rest of the firm carries on with client work and deadlines.
Recovery is not done until it is verified clean. Helm verifies that systems are clean before they come back, so client files and matters return without the attack hidden inside them.
Every step is logged with a timestamp, giving you the facts for a GDPR notification, your insurer and the client’s general counsel when they ask what happened.
Ransomware will keep targeting firms that hold valuable client information. With Helm, attacks are contained in seconds, client work carries on, and files come back only once they are verified clean.
Many of your clients in financial services face the same questions from their own regulators. To see what this looks like for your firm, talk to us.
