Distributed denial of service protection firm Radware Ltd. has acquired cloud-based security firm Seculert for an undisclosed sum.

Founded in 2012, Seculert offers a software-as-a-service security platform that aims to fill gaps left by legacy perimeter defense and breach detection systems. It claims to protect enterprises from advanced threats by focusing on malicious outbound network traffic. The company’s platform combines big data analytics, machine learning technology and behavioral analysis to provide visibility on the final two stages of the malware kill chain.

Seculert’s Javelin service is claimed to be the first inside-out attack simulation and remediation service that allows enterprises to determine how well their secure web gateway, next-generation firewalls or proxy would do at preventing real world malicious malware attacks from succeeding in communicating with their perpetrator’s command and control servers. Complementing Javelin is the company’s Shield service for analyzing secure web gateways, proxies and next-generation firewall logs to detect the presence of attackers utilizing evasive techniques.

Radware said it would use Seculert’s technology to enhance its attack mitigation system with the addition of advanced threat analytics based on behavioral analysis and machine learning using big data processing.

“The Seculert acquisition allows Radware to leverage machine learning technology and its data analytics platform in order to expand our core expertise beyond attack analysis to threat analysis, which provides a panoramic view of the data center’s posture,” Radware Chief Technology Officer David Aviv said in a statement. “These capabilities expand Radware’s attack mitigation from real-time and near-time to include detection of stealth attack campaigns.”

Coming into the acquisition, Seculert has raised $15.85 million over three rounds from investors including Norwest Venture Partners, Sequoia Capital and YL Ventures.
