Arlington-based Endgame, the maker of security and intelligence software for large enterprises, has raised $30 million from a slate of New York and Silicon Valley investors as the company looks to push further into the private sector.

Endgame started selling its cybersecurity software to financial services and consumer technology companies earlier this year after focusing on the federal government as its primary customer. Chief executive Nate Fick said the latest capital infusion will help the company pursue more commercial customers.

“The federal threats and the commercial threats look increasingly similar,” Fick said. “Their needs are increasingly similar.”

Founded in 2008, Endgame monitors an organization’s computer networks and data servers for potential security breaches, including cyber attacks from outside the organization and suspicious activity on the inside.

Fick joined Endgame as chief executive in December 2012. He most recently served as chief executive of the Center for a New American Security, a District-based nonpartisan research organization focused on national security and defense policy.

The privately held company said last month that the first nine months of the year brought “record growth,” including triple the sales compared to the prior year and the addition of roughly 40 employees. Fick declined to provide sales or revenue figures.

Endgame counts 100 employees across the country, including its engineering hubs in Arlington, San Francisco, San Antonio, Texas, and Melbourne, Fla. The company is on pace to hire a new employee each week and Fick expects that to continue into the new year.

“We feel like we have a footprint here that allows us to draw on four of the best cybersecurity talent pools in the country,” he said.

The announcement Wednesday marks the third round of funding for Endgame. The company has raised a total $90 million to date, including a $23 million investment announced in March of last year.

Edgemore Capital and Top Tier Capital Partners led the latest funding round, with participation from Savano Capital Partners. Prior investors include Bessemer Venture Partners, Paladin Capital Group, Columbia Capital, and Kleiner Perkins Caufield & Byers.

“Cyber attacks have escalated from common nuisance malware to highly targeted attacks that compromise national security and cost businesses hundreds of millions of dollars per breach. Endgame brings the military-grade technology and skill sets to counter these threats,” David Cowan, partner at Bessemer Venture Partners, said in a statement .
