A security startup called Elastica came out of stealth mode on Tuesday, and brought with it $6.3 million in venture capital from the Mayfield Fund. Elastica tries to protect corporate data scattered across the dozens of cloud services companies might be using and, like so many other security startups, is touting its use of data science techniques to accomplish its goal. Elastica does have an impressive pedigree, though, both with the Ph.Ds. on its founding team and with advisers including Rayid Ghani (Obama for America, Edgeflip), Tom Reilly (ArcSight, Cloudera), M.C. Srivas (MapR) and Ion Stoica (UC Berkeley, Conviva, Databricks).
