MDaemon Technologies SecurityGateway
Startups and SMBs that need email security without the complexity of managing separate point tools should choose SecurityGateway; it bundles anti-spam, DLP, archiving, and email continuity into one hybrid deployment that doesn't require a dedicated email security team. The 70+ pre-configured DLP rules and integrated quarantine management with user self-service reduce operational overhead significantly. Skip this if your organization runs primarily cloud-native email with no on-premises infrastructure or needs advanced threat hunting and forensics; SecurityGateway prioritizes filtering and compliance over investigation depth.
Infrastructure teams managing high-volume mail servers should choose Rspamd for its lightweight filtering engine that doesn't degrade throughput the way heavier solutions do. The 2,396 GitHub stars and active open-source community signal solid production stability, and its modular architecture means you integrate exactly what you need into your MTA stack rather than replacing it. Skip this if your organization needs centralized policy management and reporting across multiple mail nodes; Rspamd is a filtering tool, not an enterprise email security platform.
