We have security measures in place at our offices, including CCTV and building access controls.
There are signs in our office showing that CCTV is in operation. The images captured are securely stored and only accessed on a need to know basis (e.g. to look into an incident). CCTV recordings are typically automatically overwritten after a short period of time unless an issue is identified that requires investigation (such as a theft).
We require visitors to our offices to sign in at reception and keep a record of visitors for a short period of time. Our visitor records are securely stored and only accessible on a need to know basis (e.g. to look into an incident).
