The environment is a startup with less than 20 people. They use Windows, Mac and Linux systems.
A wireless router is the source of internet for their desktops and laptops. They have their personal phones which can connect to WiFi.
Some systems might have bluetooth too.
- The boss does not want them taking out sensitive company data via email or via pen drives or external hard disks or CD's/DVD's.
- Websites they visit, softwares they download and softwares they install are to be monitored and logged.
Need software (one or many) recommendation for the above.
The logs created by the software will be used for audit.
Preferably free and open source software.
Paid ones are also welcome.
Will separate software be required for each OS type?
