Irvine-based CrowdStrike Inc. has raised $100 million in its latest funding round, the second time the security software maker has hit that investment benchmark.

The Series D round was led by current investor Accel. Other prior backers include CapitalG, formerly Google Capital, and Warburg Pincus. New investors include March Capital Partners and CrowdStrike customer Telstra.

CrowdStrike, which was established in 2011 by former executives from McAfee Inc. and Networks in Motion Inc., has now raised $248 million to date with a valuation eclipsing $1 billion, the company said.

Proceeds from the current round will fund global expansion and help meet demand for its CrowdStrike Falcon product for endpoint protection.

The software maker has seen revenue zoom well past $50 million with a roster of hundreds of government agencies and Fortune 500 customers that pay a monthly subscription for cloud-based software services.

Its produces aim to detect, prevent and respond to security threats and attacks and provide monitoring, cyber intelligence services, and Big Data analytics.

CrowsdStrike first hit the $100 million fundraising milestone in July 2015 in a Series C round led by Google Capital.

The funding comes amid a global security breach carried out last weekend, dubbed the WannaCry malware attack, which targeted businesses, governments and hospitals globally and crippled 200,000 computers.

Irvine-based software security maker Cylance Inc. matched the $100 million funding benchmark last year in a Series D round led by Blackstone Tactical Opportunities.

Its software fuses machine learning, artificial intelligence algorithms, and the cloud to thwart new and evolving threats and cyber attacks before they hit servers, desktops and virtual desktops.
