We have experienced a data incident impacting a small number of storage servers.

Investigations to date have confirmed that data in our core systems, including our email and document management system, has not been affected. The firm continues to operate normally with some disruption arising from steps taken to contain the incident.  

Our technical response team, working alongside an independent cybersecurity adviser, took immediate action to isolate and contain the incident.

Detailed cyber forensic work continues to investigate and remediate the incident. As a matter of priority, we are assessing exactly what data has been impacted, and we are informing affected clients.  

We appreciate that this is an important matter for our clients, and we take this very seriously. 

Keeping our clients’ data safe, secure, and confidential is an absolute priority.
