Exponential-e
Innovation is at the core of Exponential-e, and has been since our inception in 2002. We wholly own our superfast Network, and our fusion of complementary technologies - a carrier-class Network and Cloud infrastructure - means we can deliver enterprise applications at wire speed for a superior end-user experience. Technology is the beating heart of your business, and is undoubtedly fuelling your growth and sustaining your competitive advantage. What you don’t need is the complexity that comes with multiple service providers and varying service levels. At Exponential-e, we strive to constantly exceed expectations in innovation and service; what’s more we can provide a single end-to-end SLA. At Exponential-e, our Cloud services do not transcend the public Internet. Instead, they reside on a customer's LAN, on the clean side of the firewall, so security and privacy concerns are negated. Our vast product portfolio enables us to create tailored solutions for each individual customer, ensuring that we meet their exact needs and requirements – whether that be for Data Centre, Cloud, Unified Communications, Security, or IT Services. Exponential-e has been awarded 8 ISO accreditations and is supported by a UK based 24 / 7 x 365 service desk.

Arqiva
Some services simply can’t stop. Every signal, every asset, every secure connection must work, without exception. Even as the world around them grows more complex, threats become more sophisticated, and expectations rise relentlessly. For broadcasters, utilities networks, and public institutions, the non-negotiables are the same: constant performance, flawless resilience, and decisions that are secure in the face of scrutiny. Arqiva designs, builds, and operates the foundations that keeps systems, sites, and audiences connected. From cloud and IP delivery to networks, monitoring and managed services, we take on the complexity behind the scenes so our partners can move forward with confidence. Because “critical” isn’t only the emergency moment. It’s the connections that keep countless services running. It’s peak demand. It’s the promises you can’t afford to break. With deep expertise, disciplined operations, and more than 100 years of delivery behind us, we’re the team you don’t have to second-guess. We reduce risk, provide operational assurance, and enable change without disruption. So we can protect what works today and build what you’ll need next. Arqiva. Built for what’s critical
