Blue Coat Systems is growing its security business by way of acquisition.

Blue Coat today announced the acquisition of privately-held Solera Networks in an effort to bolster its Big Data security intelligence capabilities for malware and threat detection.

Sasi Murthy, senior director Product Marketing at Blue Coat, told eSecurity Planet that financial terms of the deal are not being publicly disclosed.

Solera had raised $20 million in funding from Intel Capital, Allegis Capital, Signal Peak Ventures and Trident Capital in January of 2012. Blue Coat itself was taken private in early 2012 as part of a $1.3 billion deal led by private equity firm Thoma Bravo.

The intention is to keep Solera's employees on board at Blue Coat, Murthy noted.

"The Solera team is highly innovative and has brought to market a solution that bridges a gap in the industry today," Murthy said. "We want to keep the team and innovative spirit thriving in the company, so they continue to advance state-of-the-art security."

Big Data Boost

Blue Coat wants to boost its Big Data Security analytics capabilities with the acquisition.

"The capability to record network traffic, perform deep analytics to determine root cause and protect against threats sets them apart from vendors in adjacent markets," Murthy said.

The move toward utilizing Big Data analytics for security is not a new one.

Symantec, IBM and Juniper are among vendors embracing the trend. Blue Coat itself has had a cloud-based intelligence service known as Web Pulse since at least 2009.

Murthy noted that increasing volumes of Internet traffic are now being protected with SSL encryption. Thus there is a real need for enterprises to be able to inspect and understand the content of encrypted traffic and set policies for it from a security perspective.

"We see the future of the industry is moving beyond just blocking targeted attacks to also identifying and resolving the full scope of attacks in real time," Murthy said. "By efficiently mining a very large dataset of network history to gain previously unavailable insights, Solera bridges a gap that exists in security enterprise architecture today."

Solera's key product brand is the DeepSee Platform which includes both hardware and software appliances. It's not yet clear whether Blue Coat will retain the Solera brand moving forward. The Solera technology will be incorporated into Blue Coat's Business Assurance Technology Resolution Center.

The Solera acquisition is the second in as many weeks for Blue Coat. Last week the company acquired Netronome's SSL technology business unit.
