Email Security & Protection Services
Protect your organisation with a fully managed service that defends against phishing, malware, spam and advanced email threats, alongside compliant cloud archiving and Microsoft 365 backup. Powered by Barracuda and managed by Claranet, it simplifies email security management.
Challenges we solve
Sophisticated email attacks
Without proper backup, a single accidental or malicious deletion can wipe out critical emails, SharePoint data and OneDrive files, and the recovery options built into Microsoft 365 are limited once retention windows expire.
Data loss and accidental deletion
Without proper backup, a single accidental or malicious deletion can wipe out critical emails, SharePoint data and OneDrive files with no way to recover them.
Email compliance and retention obligations
Legal hold requirements, industry regulations and data-protection law such as GDPR mean email must be retained, and deleted, according to policy, and found quickly when required. A dedicated, indexed archive makes that easier to manage.
Account takeover and credential theft
Compromised accounts are used to send fraud emails from within your organisation. You need AI-driven detection to spot anomalous behaviour and contain the breach.
What is Claranet Email Protection?
Claranet Email Protection is a comprehensive managed service that combines three pillars: email security, cloud archiving and Microsoft 365 backup — all powered by Barracuda and fully managed by Claranet.
The email security layer goes beyond what native M365 offers, providing spam and malware filtering, real-time URL sandboxing, attachment detonation, email encryption, data loss prevention and email continuity during outages. AI-powered impersonation protection detects business email compromise, account takeover attempts and socially engineered attacks in real time.
Cloud archiving provides a compliant, indexed archive with granular retention policies, legal hold, role-based access and powerful search. The M365 backup service delivers unlimited cloud-to-cloud backup for Exchange, SharePoint, OneDrive, Teams and Groups with fast point-in-time recovery.
Key benefits
- Advanced threat protection beyond native M365

- Email continuity during mail server outages

Why add email protection to Microsoft 365?
Microsoft 365 includes built-in email security, and what you get depends on your licence. But phishing, business email compromise and impersonation attacks are designed to get past native controls, and a deleted mailbox, SharePoint library or OneDrive folder can only be recovered within the limits of Microsoft's own retention settings. Claranet Email Protection adds a dedicated layer: advanced threat protection and AI-powered impersonation detection, a compliant cloud archive, and unlimited cloud-to-cloud backup, all managed by Claranet.
The three services work together. Email security reduces the threats that reach your people. Cloud archiving keeps a compliant, searchable record of your email. Microsoft 365 backup lets you recover data that is lost, deleted or encrypted. Together they cover prevention, retention and recovery.
