Penetration Tests

PENETRATIONS TESTS – Following a security survey how often do you get your security measures tested, don’t wait for the inevitable to happen! Physical penetration tests are an important way for businesses to identify any weaknesses in the security of their premises (e.g., warehouses and offices) that could be exploited by criminals.

Our visits are covertly recorded for later use in training to improve and issues we identify at the time –

Bug Sweeps

BUG SWEEPS – We have a dedicated engineer who has over 30 years’ experience, using purpose-built specialist equipment. Working with a backup team we conduct a full electronic sweep of the premises, then use separate handheld wands for near field examinations of the respective rooms / offices, computers, and telephone equipment, finally very importantly a finger-tip search examining power supplies, ceiling tiles, thus when we complete an TSCM (Technical Surveillance Countermeasures Sweep), we can tell you if there is anything there or not.

What you say in private is your business, keeping it that way is ours -
