Network Installation And Support Services

Secure and Stable Networks: the Foundation of Business Success

Your computer network is the invisible pulsing heart of your organisation. When it’s working as it should, you won’t even think about it. But when there’s a slowdown or security breach, the entire organisation is affected. In a world with ever-increasing cyber-attacks and complicated data security legislation, your network needs to be expertly installed and proactively managed.

We know that few small and medium-sized organisations have this expertise in-house. By outsourcing your network installation and network support services to Intersys, you have access to a fully accredited and experienced team at an affordable price. Whether you’re operating out of a single room, or are a multi-site organisation, we can help.

Network installation

Our Cisco-accredited engineers have years of experience working with a myriad of networking equipment, including HP, Meraki and Unifi, as well as Cisco. We can recommend suitable network hardware to meet both the size of your organisation and your budget. Our installations are thoroughly documented so that they can be easily supported post-installation.

We don’t just install new networks; we can also help with network upgrades. Our engineers have helped several London area schools enhance their network performance by upgrading core switches and access switches. Whether you need to reconfigure your existing network to ensure maximum efficiency or are setting up an entirely new system, we have you covered.
