Company History

Zycada was founded by Subbu Varadarajan and Roy Antonyraj. As a veteran of CDN space and Bot technology, Subbu understood the limitations of the accelerations purely based on cache-centric model employed in CDN and envisioned to leverage bots to accelerate dynamic content as well. As an expert in security, Roy understood that attacks by malicious bots and other rogue agents require a real-time approach to identify and thwart attacks.
Together they set out to build a new kind of delivery network that uses machine learning and artificial intelligence to dramatically improve performance and security and to deliver powerful new capabilities between the origin and the client.
