Simian is an enterprise-class Mac OS X software deployment solution with App Engine-based hosting to scale with the needs of your growing enterprise, and a future proof client based on the Munki open-source project. Here are some example features of Simian:
Deploy new or updated software by targeting a single Mac or tens of thousands.
Push security patches, whether the Mac is on an internal network/VPN or not.
Force immediate mandatory installation of some packages, while allowing others to be optional.
Tightly manage Apple-provided updates.
Scale without deploying and maintaining additional server infrastructure.
Dynamically target clients based on user, hostname, os version, and more.
Obtain reports on all of this and the fleet overall.
