ThreatStream™, the provider of a threat intelligence platform that identifies cyber threats and facilitates trusted threat sharing, today announced that it has raised $22 million in series B funding led by General Catalyst Partners, with significant investment by new investors Institutional Venture Partners and previous investors Google Ventures and Paladin Capital Group. With this investment, Steve Herrod, managing director at General Catalyst Partners, will join the ThreatStream Board of Directors, which already includes 30-year industry veteran Tom Reilly, the former CEO of ArcSight and current CEO of Cloudera.

This funding was secured based on the rapid adoption of ThreatStream OPTIC™, the first community-vetted threat-sharing platform to manage the entire life-cycle of security threat intelligence. Since the company's founding in February 2013, more than 1,100 registered users from Fortune 1000 and government organizations have deployed the ThreatStream OPTIC platform, which analyzes threat intelligence feeds from hundreds of sources, digitally integrating that intelligence into the operations of customer organizations existing security devices. Building on the momentum of the past year, ThreatStream will use this funding to ensure customer success as well as to further accelerate growth and revenue.

ThreatStream is led by former founder, chief technology officer (CTO) and executive vice president of research and development at ArcSight, Hugh Njemanze. Njemanze is regarded as the initial architect of Security Information and Event Management (SIEM) and helped establish ArcSight as one of the most successful security companies to come out of Silicon Valley in the last two decades.

'Today the bad guys are winning because they are collaborating. ThreatStream is committed to providing the tools to enable companies to share threat intelligence in a practical and effective environment,' said Njemanze. 'The pedigree of our investors and board members, together with the experience our team has gained building successful security companies like ArcSight, makes me confident in our ability to execute and grow our business with this additional investment.'

Growing threat complexity, frequency of attacks, rapidly growing data volumes and number of locations data is stored are complicating the ability of enterprise organizations to ensure that IT infrastructure and business-critical data are protected. Despite significant investments in people, capital and security tools, organizations are struggling to win the war against cyber threats. At the heart of protecting organizations from cyber threats and their customers from data breaches is the speed at which risks can be identified. Security teams spend significant time analyzing the same attacks but lack the visibility needed to aggregate and analyze threats according to risk.

IDC predicts threat intelligence will grow to a $1.4 billion industry by 2018. ThreatStream is well positioned for market leadership, offering the first threat intelligence platform that truly changes the game for enterprise and government organizations. The unique OPTIC platform enables security teams to optimize work-flows by enabling community collaboration and analysis, then ranking threats according to severity and relevance.

Investor perspective:

'With the daily drumbeat of sophisticated security breaches, it is vital that companies across all industries augment their infrastructure to combat advanced malware and increase their defenses,' said Steve Herrod, managing director at General Catalyst. 'We are excited to back a visionary like ThreatStream, which is focused on developing a new category of actionable threat intelligence that helps companies make sense of millions of threats in real-time while allowing them to securely share their findings.'

'ThreatStream offers enterprise customers a revolutionary model to protect their sensitive data and core infrastructure. In addition, the company is led a by a true visionary in Hugh Njemanze, and we are excited to be working with him once again,' stated Steve Harrick, general partner, Institutional Venture Partners (IVP).
