Crossword Cybersecurity is a London-based provider of cybersecurity services and advisory consulting. It works with CISOs and IT leaders to assess and improve security posture through an integrated mix of services and software, reducing the need to coordinate with multiple suppliers. Its core offerings include supply chain cybersecurity with the Rizikon platform, managed services and incident response, and end-to-end consulting covering GRC, security architecture and engineering, and penetration testing. The portfolio also includes dark web monitoring through the Trillion platform, and an innovation program that links university research with acquisitions to address longer-term cybersecurity risks.

Crossword serves organizations across a range of industries seeking integrated, end-to-end cybersecurity solutions rather than juggling multiple vendors. Based in London, the company operates with a compact team and has pursued growth through new practices, such as the CyberAI offering introduced in 2024 to address risks from generative AI.
