Irvine based cybersecurity startup Cylance which provides AI based cyber-security services to organizations just like its competitor CrowdStrike which recently raised a huge $200 million to expand its services has now raised a huge $120 million in a Series E round from investment company and asset manager Blackstone to boost up its math based cyber-security solutions which it provides to its global customers around the world.

Cylance is getting this huge investment from Blackstone who also led its most previous Series D round where the company raised $100 million from a slew of investors which also included Dell Ventures, DFJ, Khosla Ventures, Capital One, KKR, IVP amongst others.

The company which reached a $100 million annual revenue rate early this year has now raised a total of $297 million since its inception just 6 years ago.

The company counts 4,000 enterprise customers currently using and paying for its cyber-security products with many huge companies, government agencies and other institutions widely adopting its computer security services.

Some of the notable customers using its flagship enterprise products currently include Gap Inc, Panasonic, Netgear, Cardigm and notable IP tech company TiVo Corporation amongst a growing list of others.

Cylance was notably co-founded by Stuart McClure who was previously a co-founder of a startup Foundstone which was counts Crowdstrike CEO and founder George Kultz as a member of its founding team.

The valuation at which Cylance raised this huge round of funding hasn’t yet been disclosed but the company was previously valued at a huge $1 Billion from its most recent rounds of funding so its very plausible that this valuation has increased with this new round, Major competitor CrowdStrike just yesterday disclosed raising $200 million at a huge $3 Billion valuation to expand its competing AI cyber-security products which it also provides to a huge range of global customers as is the case with Cylance.
