Developed by the Centre for Artificial Intelligence and Robotics (CAIR) of the Defence Research and Development Organisation (DRDO), NETRA is a native system developed by Indian scientists and other staff.
It was built with the intent of combating threats both internal and external by monitoring real-time Internet traffic.
NETRA has apparently been fully functional since 2014 and is used by the Intelligence Bureau and the Research and Analysis Wing.
NETRA has the capability to intercept and analyse data (including voice traffic) passing through Google, Skype, and other social networking forums.
It can also track keywords from emails, tweets, Facebook status updates, comments, blogs, messages on forums, and even images shared over the Internet.
