For more than four years

For more than four years, we've been delighted with CSA's managed services. We utilize two of their offerings: AppGuard Managed Service and SOC Service. As an AppGuard Platinum MSSP, they are the sole providers of AppGuard Managed Services in the UK. Despite significant expansion since the start of our collaboration, CSA has maintained an exceptional focus on security and customer relations. The senior management remains deeply attuned to client needs and expertly addresses them. Their team is remarkably responsive and possesses extensive expertise in security matters. We wholeheartedly recommend them to all organizations we work with, regardless of their size.

Excellent Cyber Security Partner

CSA Cyber have been our trusted cyber security experts for two years, providing a comprehensive range of services that keep our business safe. Their 24/7 monitoring gives us peace of mind, and the open channel of communication means we can always reach them when needed. Professional, reliable, and proactive – we highly recommend CSA Cyber.

Great partner to work with

Great partner to work with. CSA's onboarding, comms and solution deployment goes above and beyond what we were expecting, often going to great lengths to help us overcome environment specific issues. I would highly recommend.

CSA's Managed Services

We have been a managed services customer of CSA for over 4 years and are totally happy with the service. We have two services from them, AppGuard Managed Service and SOC Service. They are an AppGuard Platinum MSSP and currently provide all AppGuard Managed Services in the UK. They have grown considerably since we started our contract and have managed to keep their 'security first' posture and customer management very good throughout their growth. The senior management are all very much in touch with their customer's needs and how to meet those needs. The entire team are extremely responsive and highly skilled in all things security - we freely recommend them for all sizes of organisations we deal with.

Great Cyber Security Partner

CSA provide excellent services and consultancy for all of our Cyber Security needs. They take the time to understand our business and work with us to target requirements effectively and deliver on time. Their monitoring service is second to none and I would highly recommend for any business that cannot afford to have specialist security experts in house
