What's included
Every layer of email protection — managed for you.
Email is the #1 attack vector for every organization. Aegisys manages Barracuda Email Security so your defences stay current, correctly configured, and actively monitored.
Multi-layer inbound filtering
Spam, malware, ransomware, and phishing emails are blocked before they reach your users. Multiple detection engines run in parallel for maximum catch rates.
- Anti-spam with machine learning scoring
- Malware and ransomware attachment scanning
- URL link protection and rewriting
- Rate limiting and sender reputation analysis
Advanced threat sandboxing
Suspicious attachments and links are detonated in an isolated sandbox environment before delivery — catching zero-day threats that signature-based tools miss.
- Dynamic analysis of unknown file types
- Zero-day exploit detection
- Behavioural detonation in isolated environment
- Holds delivery until analysis completes
Business email compromise protection
Detects and blocks account takeover attempts, lookalike domain attacks, and display name spoofing — the most common vectors for wire fraud targeting professional firms.
- Domain lookalike detection
- Display name impersonation alerts
- Account takeover indicators
- Sender authentication (SPF, DKIM, DMARC)
Outbound email security
Prevents your domain from being used to send spam or malware — protecting your firm's email reputation and ensuring outbound messages meet compliance requirements.
- Outbound content scanning and filtering
- DLP policy enforcement on outbound mail
- Encryption for sensitive communications
- Quarantine and alert for policy violations
Automated incident response
Integrated with Barracuda SOAR — when a threat is detected, malicious emails are automatically removed from all mailboxes across your organization without manual intervention.
- Post-delivery threat removal across all mailboxes
- Automatic account lock on compromise indicators
- SOAR-powered remediation workflows
- Integrated with Aegisys 24/7 SOC
Microsoft 365 native integration
Deploys directly into Microsoft 365 via API — no MX record changes required. Full visibility into your existing M365 mail flow with enhanced protection layered on top.
- API-based M365 integration — no MX changes
- Teams message scanning available
- Unified admin console
- Compatible with Exchange Online Protection
Doc says:
“Email filtering alone isn't enough — it has to work together with your SOC. When Barracuda Email Security detects a threat, that signal feeds directly into Barracuda XDR and our 24/7 Security Operations Centre. The moment a malicious email is confirmed, SOAR automation pulls it from every mailbox — before anyone has a chance to click.”
