The NHS has signed a deal with Zscaler a cloud-based security and bandwidth management company.

A document seen by IT Pro detailed a Zscaler webinar stating the NHS was a customer, even though no formal announcement has been made.

Zscaler's product offering sends all customer traffic through the cloud, analyses it and then allows organisations to add policies on both security and bandwidth management.

No further details on the contract have been officially released.

The service could feasibly run through the NHS N3 broadband network, which is provided by BT. The telecoms giant confirmed a deal was in place.

At the time of publication, however, neither Zscaler nor BT had provided further details on the NHS agreement or whether it would go through the N3 network.

N3 is one of the biggest virtual private networks in Europe. It is used to manage the NHS electronic booking service and the electronic transmission of prescriptions. Essentially, it handles plenty of important data, which evidently needs protection.

To date, 180 million prescription messages and 14 million bookings have been sent over N3.

The NHS contract represents a big win for Zscaler, which looks set to provide protection for 1.3 million users operating over N3. The company provides software-as-a-service (SaaS) security, running customers' traffic through over 40 of its data centres to protect against threats.
