Expert on the implications and requirements of:
Martyn’s Law
Officially the Terrorism (Protection of Premises) Act 2025, awaiting for HM Government & the SIA to produce the 'Statutory Guidance policies' which will mainly focus on the requirements and regulation regime, at Surelock we have consultancy services, which detail all the security/protection aspects of Martyn's Law and can deal with all the legal requirements, registration and regulation advice required to you as a client to comply with this new law, now is the time to start planning.
We are fully up to date and monitor every aspect/advice of NaCTSO - ProtectUK, Counter Terrorism Policing and other official bodies that may have input on these requirements of the law -
Penetration Testing
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 any issues we identify at the time –
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.
