About Cloud Gateway

Cloud Gateway was founded in 2017 with a singular vision:Connect Anything to Everything Immediately.

Cloud Gateway was born from a shared frustration that networking was being left behind. Amongst the clamour to embrace cloud technology, little thought was being given to existing on-prem operations, and even less to the corporate network connecting everything together. Expensive vendor contracts, long lead times, and poor service are still prevalent in the telecommunications sector.

Cloud Gateway is a boutique MSP provider, combining best-of-breed technology with deep network and security expertise. We are the only tech-enabled MSP in the UK market, providing public and private sector customers with a platform to view and monitor their network and security infrastructure, along with the flow of data. Our connectivity and security solutions eliminate the bottlenecks that stifle innovation and digital transformation.

The business is experiencing rapid growth and plans to accelerate this success in 2024 and beyond. We have an ambitious product roadmap and are building a team that can execute our growth strategy.

We passionately believe that our people are the greatest asset we have. Everyone in the business has an important role to play and we’re committed to supporting the development and progression of all our staff.

Company values

We are looking for an individual that understands and reflects our core values, which are;

• Fearlessly Innovate
• Learn and Adapt
• Customer-centric Excellence
• Empowerment & Ownership
