About Hornetsecurity

Cloud email security for Microsoft 365.

Hornetsecurity is a leading cloud email security provider, specialising in advanced threat protection for Microsoft 365 environments. Their platform covers the full spectrum of email-based risk — from phishing and malware filtering through to compliance archiving, encryption, and business continuity.

Rossnet is an authorised reseller of Hornetsecurity products. For organisations that Rossnet works with on AI governance or cyber resilience, Hornetsecurity provides a practical, well-regarded solution to one of the most persistent attack vectors: email.

Email remains the primary entry point for the majority of cyber incidents. A well-configured, enterprise-grade email security layer is a baseline control that every organisation should have in place — and Hornetsecurity delivers it without the complexity of legacy on-premise solutions.

Key Capabilities
Protection
Advanced Threat Protection Multi-layer email filtering — spam, phishing, malware, ransomware, and targeted spear-phishing protection for Microsoft 365 inboxes
Compliance
Compliance Archiving Tamper-proof email archiving for regulatory compliance, legal discovery, and audit — suitable for FCA-regulated firms, healthcare, and legal organisations
Continuity
Email Continuity Ensures email remains available during Microsoft 365 outages — no disruption to business communication even when upstream infrastructure fails
Encryption
Email Encryption End-to-end encryption for sensitive communications — protecting personally identifiable information, commercially sensitive data, and privileged correspondence
Why Hornetsecurity

A natural fit for organisations managing AI risk.

Organisations that Rossnet works with on AI governance and cyber resilience consistently face email security as a foundational gap. Hornetsecurity addresses it cleanly.

Microsoft 365 Native

Designed specifically for Microsoft 365 — adds a layer of protection that Microsoft's native security does not fully provide, without requiring additional infrastructure or complex integration work.

Regulatory Alignment

Compliance archiving and email encryption support obligations under GDPR, FCA rules, and sector-specific data handling requirements — relevant to a significant proportion of Rossnet's client base.

Scalable Deployment

Suitable for organisations from 10 to 10,000 seats — equally applicable to the SME professional services firm and the mid-market enterprise. No minimum scale requirement.
