Juniper Networks has paid $10 million (£6.6 million) to get its hands on tiny UK firm Webscreen Systems, a specialist in automated DDoS protection technology.

Announced by Webscreen’s parent Accumuli Security plc, the deal will see the four employees and all IP transferred to the US giant from 4 February.

Founded in 1999, Webscreen has spent a decade of obscurity developing DDoS protection software that is capable of defending against volumetric and application-layer attacks. It is sold through a dedicated channel, which will from now on include Accumuli itself.

Accumuli acquired the company in April 2011 along with managed service provider Boxing Orange for £5.9 million ($8.85 million), of which Webscreen represented around £1.5 million of the price, according to CEO Gavin Lyons.

According to Lyons, Webscreen needed further investment on a scale that only a larger vendor could make in order to stay competitive.

Customers include gaming, retail and hosting companies, although the attraction for Juniper will have been the sort of ready-to-hand IP it can quickly integrate with its own platform rather than the order book

“The acquisition of the Webscreen DDoS capability gives Juniper another asset to help protect our customers and their data centers,” said Juniper’s David Koretz.

“Webscreen’s unique, fully automated DDoS protection system assists in keeping our customers websites and web applications highly available," he said.
