Portcullis Company Profile

Portcullis is not new to the security marketplace; the foundations of our company date back to the mid-80s. While it is fair to say that the industry has been revolutionised over the past three decades, the fundamental principles of why organisations perform information security assessments have remained constant. In brief: confidentiality. Private information must remain private. It can be difficult to reconcile the need to trust the integrity of information with the need for its accessibility. Our extensive areas of expertise enable us to deliver this delicate balance.


Our security testing services enable us to show our clients exactly where they stand as regards system security. The content and methods of our assessments are constantly changing with new developments in the field, but our motivations remain the same; our clients have questions, we deliver the answers.

Security incidents can and do happen. When they do, Portcullis can be relied upon to have the expertise to respond. We will manage the situation and work to restore our client’s faith in their own systems. While Portcullis has a great deal of experience in successful responses to security incidents; we must say that effective system security can only really be achieved through advance planning and the more that we can do jointly to refine this process ahead of time, the better.

Information security is not just about the technology; so much of overall security posture is embedded within company culture, policy, processes and standards.Our consultants can offer a comprehensive overview on how to overcome the current and potential security challenges facing a vast range of different businesses.

In order to keep our clients up to date, and to ensure we remain industry leaders, Portcullis has always maintained a strong commitment to research. Research benefits the security community as a whole, our company and our clients. It costs, but it is worth it.

Across all service areas, our aim is to use the best consultants to understand what the client needs, package this skill and knowledge in efficient processes and deliver on our promises. Technical expertise alone is not enough; it has to be delivered effectively and for the right reasons.

One of the most formidable challenges facing information security is relentless change. Threats continue to evolve, the use of technology changes and businesses constantly require better access to more information. Security cannot stand in the way of this. We give our clients the opportunity to take advantage of new concepts while maintaining their security by helping them understand the risks and how to manage them.
