In February 2022, the provider experienced a cybersecurity incident involving unauthorized access to a customer database.

The organization emphasized that no service disruptions occurred as a result of the breach. It stated that security improvements were implemented to prevent recurrence. These actions demonstrate the provider’s operational scale and its response to security and regulatory obligations.
