Our verdict on Mailprotector
Mailprotector provides email security products for managed service providers and the organizations they support. Its CloudFilter product is a secure email gateway for inbound and outbound messages across Microsoft 365, Google Workspace, on-premises mail servers, hosted email environments, and POP/IMAP systems. The service is suited to MSPs and organizations that need filtering, impersonation protection, DMARC enforcement, quarantine management, and outbound data-loss prevention in one gateway. LDAP and Active Directory support also helps align administrative controls with existing directory environments.
The product's strongest area is coverage across both incoming and outgoing mail. Inbound filtering addresses spam, phishing, and malware, while outbound filtering adds DLP rule templates and attachment blocking. Impersonation detection uses known contacts and domains, and DMARC enforcement adds authentication-focused controls. Multi-layer message threat scoring supports message evaluation across authentication checks, reputation data, content inspection, and threat scoring. These capabilities make Mailprotector a fit for organizations that want more than inbound spam filtering, particularly where outbound policy enforcement matters.
Quarantine review includes safe preview, one-click release or blocking, and administrative filtering policies with an audit trail. That combination gives IT teams a defined workflow for reviewing messages and tracking policy activity. Mailprotector supports hosted and on-premises environments, which suits mixed or legacy mail estates, while its gateway model may be more infrastructure than a small organization needs if it only wants basic filtering. Pricing uses a contact-sales model, so buyers should expect a sales-led evaluation before selecting the service. Choose Mailprotector for broad gateway coverage and practical DLP controls; consider a narrower product when simpler deployment or basic filtering is the priority.
