Hornetsecurity
Email and cloud messaging security services for Microsoft 365 and mail servers
Hornetsecurity operates in email and cloud messaging security. Its services address malware and phishing defences, email encryption, archiving, backup and continuity for business messaging, with a strong focus on Microsoft 365 environments.
The tooling is delivered as a cloud-managed layer that integrates via gateways, journals or connectors to Microsoft 365 or on-premises mail servers. It is used where organisations want separate retention, filtering and continuity controls alongside native platform capabilities and require scalable, centralised message handling.
Deployment Context
Suitable for organisations that run Microsoft 365 or mixed mail estates and need a distinct email protection and retention layer. Deployments require centralised administration, explicit message routing and audit trails to meet retention and investigative needs. Operational focus falls on aligning message policies with platform controls, mailbox permissions and identity management. The approach is relevant where teams require independent backup and continuity arrangements, segregated archiving for governance, and improved visibility into inbound and outbound messaging flows.
