Email Security
Stop phishing, BEC, and payload delivery before the inbox.
Integration and support cover email security across Microsoft 365 and Google Workspace — secure email gateway, anti-phishing, BEC defence, DMARC/DKIM/SPF authentication, encryption, and archiving aligned to retention obligations.
"Authenticate every message. Preserve what compliance requires."
API and MX integration for both.
Phased path from monitor to reject.
Retention, legal hold, and eDiscovery.

Sender authentication baseline
- SPF
Authorised senders published in DNS, hard-fail enforcement.
- DKIM
Cryptographic signing on every outbound stream and third-party sender.
- DMARC
Aligned reject policy with visibility on failing forwarders.
- BIMI
Verified brand mark rendering for authenticated mail.
Scope in detail
- Secure Email Gateway (SEG)
Inbound and outbound filtering that blocks spam, malware, and malicious URLs before they reach the inbox, with sandboxing, URL rewriting, and attachment detonation for advanced threats.
- Anti-Phishing & BEC Defence
AI-driven impersonation detection, brand-spoofing analysis, and vendor-fraud protection to stop business email compromise, invoice fraud, and credential-harvesting campaigns.
- DMARC, DKIM & SPF
Email authentication deployment, alignment monitoring, and reporting to protect the domain from spoofing and improve deliverability of legitimate mail.
- Email Encryption
Policy-based TLS, S/MIME, and end-to-end encryption for sensitive communications, with automatic classification and recipient-side access controls.
- Email Archiving & Compliance
Immutable archiving for legal hold, eDiscovery, and regulatory retention with defensible chain of custody and search across the archive.
Mailflow risks to close
- Phishing still bypasses traditional filters
The majority of breaches start with a phishing email, and traditional filters miss AI-generated lures.
- BEC and vendor fraud bypass filters
Impersonation attacks carry no malware or bad links — they exploit trust, not technology.
- Domain spoofing damages the brand
Without DMARC enforcement, external senders can spoof the domain to customers and partners.
- Retention and eDiscovery are manual
Legal and compliance requests take weeks and mailbox searches remain slow and incomplete.
Platform integration
Platforms are chosen to match the existing mail estate and licence position.

Rollout roadmap
An email-security programme that stops threats at the gateway, authenticates every message, and preserves what compliance demands.
- Assess
Current email posture audit, DMARC alignment baseline, BEC exposure assessment, and prioritised risk report.
- Design
Target SEG, anti-phishing, DMARC enforcement, encryption, and archiving architecture aligned to compliance.
- Implement
Roll out gateway, authentication, encryption, and archiving controls in prioritised waves with user awareness enablement.
- Manage
Ongoing email-threat operations, DMARC monitoring, and reporting on blocked threats and user-reported phishing.
End-to-End IT Integration and Support
From assessment and solution design through implementation, remediation, ongoing support, and lifecycle optimization.
Fix What's Broken — Remediation Sprints
Phishing, BEC or spoofing still landing in inboxes despite existing email security defaults? We run fixed-scope email-security remediation sprints across your gateway, authentication protocols, and user-awareness stack.
- Secure Email Gateway (SEG) tuning, policy cleanup and quarantine hygiene
- SPF, DKIM and DMARC alignment to enforcement (p=reject) with reporting
- BEC/impersonation controls, attachment sandboxing and URL rewrite fixes
