## From the vendor

Trustifi is an email security platform from Trustifi for Microsoft 365 and Google Workspace deployments. Founded in 2005 and based in Las Vegas, Nevada, USA, it combines three primary modules: Inbound Shield for phishing and malware filtering using AI-powered threat detection; Outbound Shield for data loss prevention and NSA-grade end-to-end email encryption; and Archive for email retention, compliance and eDiscovery support. The platform integrates with Microsoft 365 and Google Workspace through API-based scanning and centralized Outlook add-in deployment, allowing email security without requiring email relay or complex gateway configuration. Inbound Shield blocks spoofing and impersonation attacks while detecting advanced threats through multi-layered scanning. Outbound Shield enforces granular DLP rules and automatically encrypts emails containing sensitive information, including automatic encryption of sensitive images via optical character recognition. Trustifi supports multi-tenant deployments with a dedicated MSSP dashboard for managing multiple customer email security instances from a single console, which suits MSPs reselling email security to their own customer base. Pricing starts at $3 per mailbox per month (checked September 2026), though most deployments are quoted based on volume and feature tier selection. Email archiving is charged separately at approximately $4 per mailbox per month and includes retention management, legal hold capabilities and eDiscovery for compliance needs. The platform includes a free trial lasting up to 90 days, allowing hands-on evaluation before purchase, plus security awareness training capabilities added in 2026 and automatic failover for business continuity during email service disruptions. MSPs should verify that Trustifi's specific feature tier covers their resale requirements before comparing pricing against competitors like Mimecast or Proofpoint Essentials, and confirm the trial period is sufficient to evaluate the multi-tenant console and MSSP reporting capabilities before committing to production.

## Our take

Trustifi stands out for MSPs who want to resell email security through a dedicated multi-tenant console rather than direct end-user licensing. It suits shops deploying across many Microsoft 365 tenants or Google Workspace instances and wanting API-based integration without email relay complexity. Pricing is quote-based, so confirm the per-mailbox rate and feature tier match your needs before comparing against Mimecast or Proofpoint Essentials. Check whether email archiving at $4 per mailbox per month is included in your core tier or billed separately. Verify the trial covers all features you plan to resell.

## Pricing

Trustifi starts at US$3.00 per mailbox per month, according to the vendor.
