Recommended AsyncOS version for IronPort ESA C195

[jjtech]

Hi,

Which AsyncOS version is recommended for Cisco Ironport ESA C195, which one is the most stable in your experience, 14 or 15 ?

Late 14... I'm on 15.5.1 and haven't seen any issues, but 15.0 was problematic for some people as Cisco upgraded the OS under it all so it took a while to surface all of the bugs.

any from 14.2.x.
from 15.x - 15.0.1 or 15.5
