Bitdefender GravityZone Extended Email Security
Mid-market and enterprise security teams drowning in phishing and BEC attacks should run Bitdefender GravityZone Extended Email Security; its dual SEG and API deployment options let you protect Microsoft 365 without ripping out your existing email infrastructure. The platform catches impersonation and polymorphic threats at pre-delivery and post-delivery stages, meaning you're not betting everything on a single choke point. Skip this if you need deep integration with non-Microsoft email systems or demand granular SOAR-style playbooks for incident response; Bitdefender prioritizes detection and containment over post-breach automation.
Mid-market and enterprise security teams managing Microsoft 365 will get the most from TrustLayer Mail because it blocks inbound threats without forcing MX record changes, cutting through the deployment friction that kills most email security projects. Click-time URL scanning catches phishing that gateway filters miss, and the compliant archiving with eDiscovery eliminates the need for a separate archive tool. Skip this if you need on-premises Exchange support or are heavily invested in third-party email systems; TrustLayer's strength is specifically in 365 environments where transport rules and connectors handle the heavy lifting.
