About Us

Our History

Continuous growth achieved through service excellence and innovation.

Founded in 1969 by two former Police Officers, Complete Integrated Solutions (CIS) Security Limited initially operated as a security management and commercial investigation specialist, advising clients on matters relating to best security practice, and providing a loss prevention and investigation service. In 1972, the Company entered the guarding industry.

CIS Security felt that there was a gap in the security market which would benefit from a professional Security company with a strong management support structure, and an independent approach with integrity of service.

Over the years, the Company’s growth has been achieved through a combination of recommendation from existing clients and new opportunities.

Based in London, today CIS is a solid and independently-owned business providing security solutions all across the UK.
