Tried, Tested and Proven

poppyAs we remembered the fallen from wars, many of whom were less than 22 years old, and we marked the milestone of 100 years since the beginning of the Great war; Portcullis also marked its own milestone as one of the longest established companies in IT Security.


In this last year alone Portcullis has taken on many more people to meet the increased demand from our clients and to accommodate them all, we moved into our brand new Head Quarters in Watford, quadrupling the office space from what we had before. Although geographically not far from our old HQ in Pinner; in terms of facilities, it is miles away from the Tudor pile we used to occupy. Our new office is a secure facility with all mod cons and state of the art communications. We even have a permanent Portcullis Arms to cater for everyones epicurean needs.

There are very few companies who have been around as long as Portcullis in the information security space and as the industry grows we strive to keep at the sharp end of innovation and technology. Blending the heritage of our illustrious past with the pioneering spirit of a trailblazer.

Portcullis Security is a privately owned company. The brand was established in 1986 and was fully incorporated in 1992 as Portcullis Computer Security Ltd. The same three visionary Directors still run the company today.

Having developed extensive and strong relationships throughout the IT Security Industry, Portcullis is one of the most highly regarded IT Security Companies in the UK. It has been involved in or been the instigator of many of the UKs security initiatives, including organisational schemes such as CHECK, CREST and the Security Researchers Information Exchange (SRIE).

Portcullis client base incorporates; Central and Local Government, Banks, Manufacturing, Charities, Telecoms, Utilities, Pharmaceuticals, Insurance, Retail, Healthcare, Energy, Education, Fast Moving, Consumer Goods, Technology, Financial Services and Media with many in the FTSE 100.
