History

Network Security Systems Europe was established in the early 1990s to provide organisations with both IT infrastructure and backup power solutions, with particular expertise in Uninterruptible Power Supply (UPS) systems.

In 1998, NSSE made the strategic decision to specialise exclusively in backup power and power protection. By partnering with a carefully selected group of leading UPS manufacturers while remaining fully independent, we were able to offer impartial technical guidance and recommend solutions based on each client’s operational requirements rather than a single manufacturer’s product range.

Today, with more than three decades of experience, NSSE is a trusted UK provider of critical power solutions. Our capabilities extend beyond UPS systems and standby generators to include switchgear, server racks, cabinets, power distribution units, cabling and associated infrastructure.

We support clients throughout the complete project lifecycle, from initial consultation and system design through to supply, installation, commissioning and ongoing maintenance. Our technical and service teams provide responsive, dependable support, helping clients protect critical operations, reduce risk and maintain business continuity.

Our collaborative approach allows us to work closely with electrical contractors, M&E consultants, resellers and end users. Supported by experienced installation and service partners, together with a trusted network of specialist suppliers, we deliver efficient, well-coordinated solutions tailored to the technical, commercial and operational needs of each project.
