Today's acquistion of ViewFinity (an endpoint privilege escalation vendor) by CyberArk signals an important taxonomy shift in Priivileged Identity / Access Management.
Of major PIM suite vendors, BeyondTrust, CA Technologies and Centrify have their own endpoint privilege escalation solutions for Windows and Linux. Dell and Microfocus have only Linux based solutions. Balabit, Hitachi-ID, Lieberman, and Thycotic do not have any, they usually partner with Avecto, and Bit9.
Today's acquisition will a) further reduce the already small number of eligible/acquirable endpoint privilege escalation vendors and b) create further differentiation between partial and full PIM suite providers.
