Here is a value add that you can outsource. Security is a big issue and you can start offering it without any investment. Phone+ mag has an article about Authentium Security Subscription:
ESP for enterprises, which only works with Windows-based devices, essentially aggregates options for antivirus, antispyware, firewall, data backup and restore, and other security software into one platform to protect endpoints from “the worst of what the Internet can do to your business,” O’Donnell says. Think of ESP for enterprises as a sort of iTunes for security software. The built-in e-store lets an administrator buy licenses from multiple vendors (even competitors) through Authentium, all under one license. He or she then decides which software to allot to departments within the company, clicks a button, and ESP for enterprises downloads the specified packages to users’ PCs.
