Amazon is in advanced talks to acquire Sqrrl, a Massachusetts-based cybersecurity software company whose founders used to work for the NSA, Axios has learned.

Why it matters: Sqrrl analyzes big data to hunt cyber-threats, helping companies identify and address them faster.

Word is that the purchase price would be a bit north of $40 million, although there are still some final details to iron out.

Sqrrl had raised nearly $30 million in venture capital funding from firms like Accomplice, Matrix Partners, Rally Ventures and Spring Lake Equity Partners. Neither the Cambridge, MA-based startup nor Amazon have yet responded to requests for comment.
