About CM Security Services Limited
CM Security Services, formerly known as K4 Security Services, is built around a simple principle. Security should work for the client, not just the contract.
Every officer we deploy is SIA-licensed, BS7858 screened, briefed on the specific requirements of your site and supported by active management. Our approach goes beyond providing personnel. We focus on understanding each client’s operational and security needs, maintaining consistent standards and identifying potential issues before they escalate.
Across commercial, residential, retail and industrial environments, we build dependable working relationships through consistent teams, hands-on supervision and a proactive approach to security. By understanding the sites we protect and the people who rely on us, we aim to prevent problems rather than simply respond to them.
CM Security Services. Client-focused security, backed by the strength of K4 Group.

National Coverage
CM Security Services Limited operates across the country, but every site is staffed by officers who know the area and understand its specific risks. You get the reach of a national provider without losing the accountability of a local team. Whether your site is in central London or a regional industrial estate, the standard of service doesn’t change.
Technology That Supports Our Officers
We use modern monitoring and reporting tools to keep you informed in real time, but we don’t treat technology as a substitute for trained judgement. Cameras and alarms flag activity; our officers assess it and act. It’s this combination, not either one alone, that closes the gaps other providers leave open.
