Oregon tech's investment surge continued Wednesday with a $33 million infusion for an online security company that moved its headquarters to Portland last winter.

Twistlock developed its security technology for a field of automated software deployment known as DevOps. It's designed to bring the same speed to online security that DevOps has brought to software deployment.

Founded three years ago and formerly based in San Francisco, Twistlock's operations are now split among its Portland headquarters and offices in Israel and in New York, where chief executive Ben Bernstein works. The company's Portland offices are on the North Park Blocks, in the former headquarters of another Portland software automation company, Puppet.

"Our growth is focused here," said Josh Thorngren, Twistlock's marketing vice president and one of several Puppet alumni working at the startup. "Portland has this great background in DevOps and security."

Twistlock employs 80 companywide, including 30 in Portland. Thorngren said local employment could double in the next year as Twistlock begins spending its new capital to expand the business.

Privately held Twistlock has now raised $63 million altogether, making it one of Portland's best-funded young tech companies. San Francisco wealth management and investment firm Iconiq Capital led Wednesday's round, joined by prior Twistlock investors.

Oregon's startup scene is rebounding from a few years of sluggish activity with a series of major investments.

This summer alone, Puppet raised $42 million, Beaverton startup RFPIO raised $25 million, Portland startup Bumped raised $14.1 million, Portland real estate crowdfunding site CrowdStreet raised $8 million, and Portland-based Jama Software sold an unspecified stake in the company for $200 million.
