Does Cisco's ESA support TLS 1.3?

[tenorabile]

I haven't been able to find any details on when/how Cisco will support TLS 1.3 on the email security devices. Any links you can share?

Thank you,

Jason

It's now a year later and it seems TLS 1.3 is still not implemented. Any date by now or at least a version?

I have 14.2 beta at the moment... its not there yet...

Kind of sad. I know of some banks who want this as a requirement from their partners

It looks like we're tentatively tracking this for AsyncOS 15.0. I know it's been an ask for some time so I'll do my best to push it in any conversations. 

Thanks!

Do we have an update on this? We need that for a smtp partner of ours who insist to use TLSv1.3 only (a bank).

I'm currently in 15.0 Early Field Trial... its not there yet.
