Question Which is the best all-in-one software to manage my office and give security?

[jameswork]

Can anyone recommend the best all-in-one software that can manage my office and give security?

Most offices choose Microsoft Windows.

Kidding aside, you made no mention of your specific needs, what size office, and whether anyone is "high risk". I manage my office and it is secure "enough" with no specific 3rd party software added, just good safe computing practices, though every now and then, I upload files to virustotal to check for malware when it seems prudent. Mostly that's email attachments if a file format that is subject to vulnerabilities.
