Another day, another security startup raising tens of millions in venture capital.

Jask, which debuted its autonomous security platform at last year’s Black Hat USA conference, today said it raised $25 million in Series B funding. This brings its total to $39 million.

The company’s funding announcement comes a day after another security startup — Balbix — raised $20 million in its Series B.

Kleiner Perkins led Jask’s funding round, and Series A investors including Battery Ventures, Dell Technologies Capital, TenEleven Ventures, and Vertical Venture Partners also participated. The company said it will use the investment to further develop its security platform, increase hiring in all departments, and expand its global sales channels.

In addition to investing in the startup, Kleiner Perkins General Partner Ted Schlein joined Jask’s board of directors. Schlein was the original investor in ArcSight, which developed an autonomous security operations center platform and was acquired by HP for $1.5 billion in 2012. It was later spun out with the rest of Hewlett Packard Enterprise’s (HPE) software business to Micro Focus in 2017.

Before HP acquired ArcSight, Jask CEO and co-founder Greg Martin and VP and co-founder Damian Miller led ArcSight’s security operations business. So this is a reuniting of sorts for the three men.

Martin also founded security company ThreatStream, which rebranded as Anomali in 2016. And Schlein was an early investor in other successful security ventures including Carbon Black — which raised $152 million in its public debut last month — Mandiant, and Phantom Software.

“With one of the most experienced teams in security operations, Jask understood that the biggest challenge to cybersecurity is human talent. There are not enough people skilled in attacker methods to quickly discern a real threat from a low-risk compromise,” Schlein said in a statement. “Through advanced AI and machine learning, Jask frees security analysts from onerous data review to focus on investigating and responding to the most critical threats, improving efficiency, and reducing organizational risk exposure.

The company’s platform automates much of the work of a tier one security analyst by correlating and analyzing data and summarizing the important information via streamlined notifications that indicate a combination of events or activities that should be investigated.

Jask was founded in 2015 before emerging from stealth last year. It has dual headquarters in San Francisco and Austin, Texas.
