Real-world feedback on Mimecast highlights issues that teams are tired of working around:
Mimecast offers hosted email security and archiving with optional add-ons like awareness training and continuity. While widely used, it still relies on mail flow redirection, which adds complexity and risk during migration. Its journaling-based archiving also adds layers of configuration and maintenance — particularly in Microsoft 365 environments.
TrustLayer replaces that complexity with seamless, connector-based protection and fully integrated archiving. That means fast, compliant, tamper-proof storage, instant search and e-discovery, and no extra admin overhead. You get the coverage you need across inbound, outbound and internal traffic — without the mess.

With Mimecast, pricing can spiral as features are added — archiving, secure messaging, awareness training and support are often sold separately. TrustLayer offers one integrated platform with email security, real-time threat detection, policy controls and archiving included. No bolt-ons. No hidden costs. Just full-stack protection.
TrustLayer was head and shoulders above the rest. They clearly have a well-thought through product and unlike other products on the market, it has been designed to run in the cloud, rather than adapted for it.
When I saw a demo of TrustLayer's combined web, email and cloud (CASB) security platform at a trade show, I felt like I had stumbled across something that didn’t exist.
