I dunno if i'd be sold on a web-based antivirus... Sounds like too much "could" go wrong.
Ya I know. I had a Webex with a sales rep & an engineer of webroot. My first question was If its cloud-based, what happens when my employees arent online ? They said along with the heuristics engine there is the sandbox feature that will automatically be implemented if a process starts acting funny. Whenever a program/file is introduced to the computer it is checked with a database to see if it is known & OK, if it isnt then it is allowed but under a sandbox enviro - if the program/file proves to be legit - it is whitelisted. If it is unknown & starts acting like malware the sandbox feature can roll back any changes the file/program did.
Of course the way they explained was much more elegant. Since their Enterprise pkg is still in Beta - most of the examples were using the consumer-based version. But the 2 are the same software with the Enterprise version had more tweaking and remote management abilities. The consumer version has a remote console but is limited into what you can do.
