Trusted by our customers
David Cox, Senior Manager – OT Compliance & Cyber Security, Britvic:
“We’ve been thrilled by the strength of the working relationship we’ve built with Arcanum Cyber Security over the last two years. Their attention to detail, flexibility and willingness to work around our individual requirements has been essential to the smooth running of this security project.
We continue to have an excellent relationship with the Arcanum team and are building our cyber roadmap over the coming years to ensure our OT security remains at the highest standard possible.”
Chris Moore, VP Defence & Security and CISO, OneWeb:
“Working with Arcanum Cyber Security over the last two years has enabled us to dedicate the necessary time and resource to our compliance and governance requirements. Arcanum’s understanding of the regulatory bodies and security standards that we encounter is critical to helping us deliver the quality network we require.”
Prof. Ingo Waldmann, CTO & Co-founder, Spaceflux:
“Arcanum’s penetration testing service has been instrumental in validating that our systems are secure by design and verify we meet our cyber security compliances. Their expert team didn’t just test our defences — they helped us proactively identify and resolve vulnerabilities. They have always been very flexible and accommodating to our needs and specific requirements, giving us the independent assurance needed to demonstrate the robustness of our security architecture.”
Mark Eagles, Information Security Analyst, ZSL:
“ZSL has benefitted a huge amount from this assessment and your patient support and advice over the past year, which has left us in a much better state for Cyber Security than when we started. Please accept my sincere thanks to the penetration testing team and everyone that helped from Arcanum throughout the assessments over the past year, and for your support with Cyber Essentials Plus. We look forward to working with you again in the future.”
