Barracuda email security works effectively with O365, and we have been able to achieve many use cases that other competitive products such as Micro, Fortinet, Trellix, or Forcepoint could not accomplish.
Barracuda Backup excels in scalability, supporting growth from Office365 with one terabyte to enterprise solutions for 1000 users as thin VMware storage, without licensing costs per server or VM. Cloud-based, it eliminates hardware needs, while integrating email security with O365. However, it requires reporting and backup improvements for Linux/Unix, better VM functionality, and enhanced support. Postgres SQL backup integration is unsupported, impacting functionality and support due to time zone differences.
