Question to the Ministry of Justice:

To ask the Secretary of State for Justice, when her Department was informed that former employees of (a) ISG and (b) ESS had access to the layout of prison estates; for what reason former employees were able to access the plans following the cessation of their employment; what assessment her Department has made of whether the former employees of other companies have had similar access; and what steps her Department is taking to prevent a similar security breach in the future.

When ISG Construction Limited entered administration on 20 September 2024, the Ministry of Justice took the necessary measures to immediately secure its data. Access to the Department’s software platform was immediately revoked to former employees of ISG and ESS, and the respective subcontractors.

The Department was informed on 26 November 2024 that a small number of former employees of ISG and ESS, and the respective subcontractors, had accessed an active software platform managed by ESS following the administration. As soon as the Department was made aware of this, we liaised with the Administrator to ensure they revoked access. This was completed within 24 hours, on 27 November 2024.

The Ministry of Justice is investigating the incident and any steps required to prevent a similar incident in future.
