SentinelOne, a cybersecurity startup, completed the acquisition of Attivo Networks, an identity threat detection and response technology firm, for $617m. "The shift to hybrid work and increased cloud adoption has established identity as the new perimeter, highlighting the importance of visibility into user activity. Identity threat detection and response is the missing link in holistic XDR and zero trust strategies. Our Attivo acquisition is a natural platform progression for protecting organizations from threats at every stage of the attack lifecycle," Nicholas Warner, SentinelOne COO.
