PowerKeeper’s software is actually implemented in an appliance, which currently supports a maximum of 10,000 systems and which, as the name suggests, acts as a gatekeeper for admins needing to access servers. Rather than having to change accesses on all of your servers for specific admins, you can change them once on PowerKeeper, which in turn controls access to all of the servers it is hooked into.

PowerKeeper supports the Solaris, AIX, and HP-UX variants of Unix plus Red Hat and Novell Linux; the appliance allows both SSH and RPC access for Unix and Linux. It also supports Windows 2000 and Windows Server 2003 platforms, but you can only use RPC.

Symark, which is based in Agoura Hills, California, was founded in 1985. It also this week announced that its PowerBroker tool, which provides granular control over root privileges on servers, now supports Solaris 10, the latest Unix from Sun Microsystems. The two companies also extended their joint marketing agreements, and Symark will push Solaris 10 to its customers as Sun peddles Symark’s tools to its customers.
