Challenges facing businesses today

Needing secure connectivity

Organisations have become hugely dependent on wifi, fixed and mobile networks. Are these provided with additional services for extra protection and peace of mind?

Securing multiple endpoints

The more devices you connect to the internet, the greater the risk from ransom/malware and other attacks. Protect endpoints with a core strategy, not individual solutions.

Network security protection

What will the security landscape look like in the future? Build and optimise your network not only for today’s security environment, but also for three or five years from now.

Moving to the cloud securely

Protecting data in the cloud today is business-critical. If you’re moving to the cloud, you’ll need to apply the same rigorous security principles as you do to your networks.

Understanding digital exposure

Do you know the weak spot in your network or external digital footprint? You can be sure someone’s trying to find it, to get hold of your intellectual property or valuable data.

Responding to cyber security threats

Larger numbers of users, devices, apps and security products to manage means that it’s getting more challenging to work out what’s really a threat, and what’s just noise.
