F5 (FFIV) has bought Defense.net, a provider of cloud-based security services for protecting against DDoS attacks. Terms are undisclosed.
The purchase follows a string of high-profile DDoS attacks affecting sites/platforms such as Vimeo, Meetup, Bit.ly, and TypePad.
Defense.net's services will complement various on-premise F5 solutions (inc. firewall and load balancing products) that can be applied towards dealing with DDoS threats. Many peers are also pairing on-premise security hardware/software with cloud services.
F5's security hardware has turned into a key growth driver as the company deals with relatively muted demand in its core application delivery controller (ADC) market, as well as some competitive pressure from software-based (virtual) ADCs. F5 mentioned on its FQ2 CC (transcript) it had two multi-million dollar security sales wins during the quarter.
