Although some seem a bit squeamish about it, any good firewall&#x2F;filtering solution should do SSL MITM --- especially now that encrypted connections are becoming the norm.<p>Given that Trend Micro themselves provide AV software that does this, it&#x27;s particularly ironic since it&#x27;s already no problem for them to decrypt and scan encrypted traffic. It&#x27;s likely just their CA division that dislikes Let&#x27;s Encrypt.
