ThreatStream, a platform for cybersecurity intelligence, has raised $4 million in Series A funding led by Google Ventures, with participation from Paladin Capital Group, Cloudera CEO Tom Reilly, also the former CEO of ArcSight and Hugh Njemanze, former CTO and Founder of ArcSight. ThreatStream will use the funding to offer a new layer of cybersecurity protection for the enterprise and government markets, enabling organizations to understand threats in context and block attacks more quickly. The company will debut its new platform at RSA Booth #2509.

Until now, enterprise security experts had to identify malicious files and IP addresses on a case-by-case basis, without insight into how different threats might be related. ThreatStream's new Optic platform aggregates threat intelligence from across the Internet, enabling organizations to analyze the connections between threats and take quicker action to block them.

'Today's cyber defenses are only as effective as the data they capture. Organizations will continue to be vulnerable if they can't track in real-time the dynamic attacks across the Web or recognize early threat indicators,' said ThreatStream CEO Greg Martin. 'ThreatStream integrates right into the security tools you already have, and gives you the visibility to stop attacks before data is lost.'

ThreatStream's SaaS-based Optic platform is the first to offer crowd-sourced cyber intelligence, which aggregates millions of threat indicators from around the Internet and integrates them directly to an organization's existing security infrastructure. Optic applies machine-learning analytics to pre-process intelligence, uncover new threat indicators, and give visibility into unknown threats within an enterprise.

'The growing number of attack vectors have made current security models less effective,' said Karim Faris, General Partner at Google Ventures. 'Instead of attempting to stop threats after they have breached your network, ThreatStream lets organizations look outside their own environments for a broader view of the attacks forming and put in place proactive defenses. It's a smarter way to analyze threats, and take action against them.'

Optic is available either on-premise, within a private cloud or via 'Optic Crowd,' a public-cloud version that offers limited free use for organizations interested in automating the sharing of cyber threats cross-industry. ThreatStream is currently accepting new product inquiries.
