We have over 10 years experience in the information security industry and have worked across all industry sectors. We pride ourselves on listening to your needs, identifying the right services and using your budget as effectively as possible.

You can call or email us whenever you like – we’re here for you even when we’re not working on a particular project for you. We’re proud that our customers call us their Trusted Advisors and not just suppliers. That proves that our professional advice is highly valued.

The Security Bureau provides quality and a personal service that is unrivalled. We know that information security is not as straightforward as a scan. It requires an eye for detail and that’s what we excel at.





The Security Bureau was founded by Marios Kyriacou, who has worked as an information security consultant for over 10 years. He developed an interest in the area during a degree in Computer Systems Engineering at the University of Sussex, and went on to develop specialist knowledge by taking a Masters in Information Security at Royal Holloway. After graduating, he took a position at a small boutique testing house, putting theory into practice. He gained the much coveted CHECK Team Leader status after only two years. Marios went on to hold senior positions in two global telecoms organisations and lead a penetration testing practice at a large security solutions provider. In addition to carrying out penetration testing and developing security services, Marios has consulted on ISO27001 and PCI standards and has acted as a Security Manager for a large global publishing organisation. He maintains links to his academic past by giving talks to students on the working in the industry and the latest attack and defence techniques.

“The Security Bureau is a practice built with the years of experience gained from working in different security consultancies and with a wide variety of customers. We know that each customer is different and has different needs. Our tailor made approach provides versatility and the results that will help you to build a business that can operate securely.”
– Marios Kyriacou
