IG Securities Public Apology After Unauthorized Data Visibility

IG Securities has issued a public apology after identifying issues in how customer personal information was handled. This involves its contractor, IG Markets Limited.

The incident relates to the processing of “specific personal information,” including sensitive identifiers such as Japan’s My Number. According to the brokerage, there is currently no confirmation that any customer data has been leaked outside IG Group.

IG Securities stated that certain employees within the wider group were able to view customer data beyond what was required for their roles. In addition, some personal information was stored on an external server operated by a cloud service provider without prior approval from IG Securities. The firm clarified that the cloud provider’s staff did not have access rights to the data. So, they were unable to view it through the system.

Following the discovery, IG Securities instructed IGM to implement system changes and remove the data from the external server. The deletion was completed on March 5, 2026.

The company reported the matter to multiple Japanese regulators and industry bodies, including financial authorities and oversight associations. Internally, it confirmed that 162,879 customer records were accessible within IG Group systems beyond the intended scope. Separately, 29,734 records had been stored on the external server.

IG Securities attributed the issue to insufficient oversight and supervision of its contractor. The firm acknowledged gaps in governance processes tied to outsourcing arrangements.

As part of corrective measures, IG Securities outlined adjustments to how customer data will be handled during account setup. My Number details will temporarily be processed in IGM’s overseas systems during review stages, after which the data will be transferred and stored within IG Securities’ infrastructure in Japan under stricter controls.

The company said it is taking steps to strengthen monitoring and data management practices to prevent similar incidents in the future.
