WiFi vendor Aruba was acquired by HPE in 2015. By that point, Niara was already born; its founders had left Aruba and raised a round of funding. That group included CEO Sriram Ramachandran and Vice President of Engineering Prasad Palkar.
Niara specializes in behavior analysis. It uses machine learning and big data to establish a baseline for normal behavior, then looks for anomalies that could indicate intrusions.
That’s in line with a current trend in security: looking for ways to minimize damage after a network has been breached. Other companies applying machine learning and/or big data techniques to this problem include startups Deepfield (being acquired by Nokia) and Vectra, as well as non-startup AT&T, with its Threat Intellect platform.
Terms of the deal were not disclosed. Niara had raised $29.4 million in two rounds, the latest one being a $20 million Series B in April 2015.
