Keeping you and your business safe

Your networks. Your devices. Your data. Secure.

The world is changing. Today, businesses have to respond to protect their networks and their people from evolving threats.

Every business needs secure communication and data access in the highly mobile world. But this comes with risk that must be managed. Data needs to be secured against hacks and interception and devices must be protected too. Getting security all joined up across the infrastructure of any organisation can be a huge, yet critical, challenge.

Whether your organisation is large or small, private or public sector, we’ve got solutions to protect your network, your people and your business.

We can help keep your data and devices safe from viruses, spam, malware and identity theft. And help you put secure, flexible working at the heart of your organisation. For us, all the connected parts of your infrastructure need to be secure.

You’re in safe hands. As part of Telefonica, we have a dedicated security unit, ElevenPaths, and access to over 1,000 security experts worldwide. And with Wayra UK, we have a team dedicated to working with start-ups to help grow and develop innovative technology solutions.
