Data Defence’s Secure Email service implements and manages advanced email and web security controls — protecting your organisation from phishing, impersonation, malware delivery, and data loss whilst ensuring your own outbound communications are trusted and deliverable.
Secure Email and Web Security
Email remains the single most common vector for cyber attacks. Phishing, business email compromise, malware delivery, and impersonation attacks are all primarily email-based — and they are becoming increasingly sophisticated, targeted, and difficult to detect without expert-managed controls.
Data Defence implements and manages layered email security using technologies including Mimecast, Microsoft Defender for Office 365, and Cloudflare — providing advanced filtering, sandboxing, impersonation protection, and data loss prevention tailored to your environment.
We also manage your email authentication posture — implementing and maintaining DMARC, DKIM, and SPF records to prevent spoofing of your domain and ensure your legitimate outbound communications are delivered reliably. Poor email authentication is one of the most exploitable weaknesses in an organisation’s outbound posture and a common gateway for supply chain attacks.
Web security controls extend protection beyond email — filtering web traffic, blocking malicious domains, and preventing users from reaching known threat infrastructure regardless of how they were directed there.
Why Choose Data Defence
Email security is a continuous management discipline, not a one-time configuration. Threat actors constantly evolve their techniques to bypass filters. Data Defence provides ongoing tuning, threat intelligence integration, and expert management to ensure your email controls remain effective against current attack methods — not just the ones that existed when the service was first configured.
Protect your inbox. Protect your reputation.
An organisation whose domain is being spoofed to attack its own clients has a reputational problem as well as a security one. Data Defence manages both your inbound protection and your outbound authentication posture — ensuring that email to and from your organisation is secure, trusted, and compliant.
