tCell Closes $9.4M Series A

Cloud infrastructures force organizations to re-architect how they do security. Traditionally, security is part of the network (e.g., firewalls, web application firewalls, intrusion prevention systems), and any cloud comes with its own built-in security. The customer's security has to go into the one thing they own - the app.

tCell enables customers to deploy self-defending apps - giving organizations application visibility and protection, with a simple deployment that embraces DevOps and is completely agnostic to infrastructure - whether it be virtualized, public/private cloud, containers, or anything else.

'We see DevOps and cloud infrastructure impacting everything in IT - including security,' said Mark Siegel, Managing Director at Menlo Ventures. 'We believe the information security market is on the cusp of significant change - with value moving from networks to software, and we are acting accordingly.'

tCell also named Steve Mullaney to the board as an independent director, gaining access to Steve's experience moving infrastructure and security markets from hardware to software at Palo Alto Networks, Nicira, and VMware. 'Many of the traditional approaches to security are limited in this new world - faster application deployments, more dynamic applications, and the loss of many of the places we used to put security - like the network,' said Steve Mullaney, director at tCell. 'Applications that defend themselves will become the new normal.'

tCell was founded in late 2014 by Michael Feiertag and Boris Chen. Previously, Michael ran products at Blue Coat and Okta, and Boris was VP of Engineering at Splunk.
