Critics who scream that Hadoop platforms lack security can now begin to calm down. Last month Hortonworks bought XA Secure, a data company that provides a comprehensive security suite for Apache Hadoop.

This morning Cloudera announced that it has acquired big data security expert Gazzang to “dramatically” strengthen its security offerings, which already includes Apache Sentry.

Cloudera claims that between Apache Sentry, Intel’s open source Project Rhino and Gazzang’s Encryption and Key Management capabilities it now offers the most robust end-to-end Hadoop security which is key to its Enterprise Data Hub strategy.

Not only that, but it also raises Cloudera’s appeal to regulated enterprises many of which may have been hesitant to adopt Hadoop until now because of the difficulties in securing and processing sensitive and legally protected data within the Hadoop ecosystem. This is key for maintaining compliance with requirements such as HIPAA-HITECH, PCI-DSS, FERPA and the EU Data Protection Directive.

Gazzang secures a number of NoSQL big data databases such as DataStax, Couchbase, MongoDB among others which may play into Cloudera’s Enterprise Data Hub aspirations leaving others to be Enterprise Data Lakes, which they want to be anyway. 

It’s important to note that while this news could ignite a spat between Hadoop distro providers, it could also do something else -- serve as a signal to CIOs that their data is safe in Hadoop and that it’s safe to swim in its waters.
