Manned Guarding

CIS Security is a privately owned and independently managed company. The Company is proud to have grown organically and will continue to do so free of any mergers or acquisitions. As a London based company, CIS Security’s continued success is reflected in its varied client portfolio of professional, public sector, financial and commercial organisations predominately in the City and West End.

Corps Security is the trading name of The Corps of Commissionaires Management Limited and was founded in 1859 by Captain Sir Edward Walter as a way to provide employment for ex-servicemen on return from the Crimean War. With our motto of 'loyalty, integrity, service', we have become the UK’s most established and respected specialist security services provider.

We've been involved with the security industry for most of our history. We introduced our first guard tour system in 1987. The PIPE was developed as a response to customer requests for an abuse-proof guard tour system.

Ultimate is London's leading security company, with 1,700 experienced security offices at more than 200 locations. We make our clients feel secure, valued, and part of the Ultimate Security team.
