HYAS CEO David Ratner said the company’s tools utilize âa combination of communication patterns and knowledge of adversary infrastructure that allows us to be very unique in detecting intrusions that no one else can find.” HYAS, a threat intelligence startup that specializes in mapping and blocking the command and control infrastructure of malicious hackers, announced it has closed out its Series B round with $16 million in new funding. The new round was led by S3 Ventures, with additional financial support from Uncorrelated Ventures, Tightline Holdings, the Cyber Mentor Fund and Dcode Capital. As part of the deal, S3 Ventures Partner Charlie Plauche will get a seat on the board of directors.
