F5 Networks it has acquired Defense.Net, a privately-held provider of cloud-based security services for protecting data centres and Internet applications from distributed denial-of-service (DDoS) attacks.
According to a statement, the advanced technologies and operational experience shared between the two companies will expand F5's portfolio of security solutions for defence against Internet-based DDoS attacks on networks, data centres and applications.
Defense.Net's high-capacity cloud service is complementary to F5's existing on-premise DDoS protection capabilities. The combination provides customers with the most comprehensive hybrid DDoS solution, engineered to absorb the full threat spectrum of DDoS attacks.
"F5's objective is to help protect customers from ever-changing security threats before they impact their businesses," said Manny Rivelo, EVP of strategic solutions at F5. "Customers ultimately want a unified solution that seamlessly blocks DDoS attacks at the appropriate network location for the type of threat posed. The appeal of a hybrid F5 solution is that it combines the best of on-premises and cloud-based protection. The highly respected team of security experts from Defense.Net is a welcome addition to F5."
Designed by DDoS industry pioneers, Defense.Net's service is supported by an advanced, high-throughput infrastructure to defend organisations against the new generation of massive and sophisticated DDoS attacks, adds F5 Networks. The Defense.Net network, it says, supports multiple protocols and provides ground-breaking features for remediation and control to safeguard customers from unforeseen threat vectors, while maintaining application performance.
The terms of the acquisition were not disclosed. The acquisition is not expected to have a material impact on F5's operating results.
According to Barrett Lyon, founder and CTO of Defense.Net, F5's DDoS product engineering shows a comparable focus on scale and performance to how Defense.Net has built its mitigation capability in the cloud.
"Customers of all sizes will be able to ensure that business-critical applications and networks are protected and available under the most demanding conditions regardless of the volume, type or source of DDoS attack. Wherever it makes the most sense to stop an attack, F5 will provide the customer with the right defence."
Sophisticated DDoS attacks combine high-volume traffic-clogging with stealthy low and slow application-targeted techniques, says John Grady, research manager for security products at IDC.
"These hybrid attacks will increasingly cause serious disruption for organisations. A defence-in-depth strategy for DDoS takes a combined approach that incorporates on-premises appliances for detecting and mitigating mid-volume, SSL or application-targeted attacks, while a cloud scrubbing facility stops the volumetric attacks that are dozens of gigabits in bandwidth from even reaching the enterprise network."
