Managed Email Security

Email is still the number-one way attackers get in. We harden your email platform, enforce DMARC, triage reported phishing and pull malicious messages out of inboxes fast.

Always-on monitoring LIVE

  • SPF, DKIM & DMARC enforcement
  • Reported-phish triage
  • BEC and impersonation detection
  • Rapid mailbox remediation

Overview

Phishing and business email compromise (BEC) remain the most common starting points for breaches and financial fraud. Attackers impersonate executives, suppliers and your own domain to steal credentials or redirect payments.

Our Managed Email Security service hardens your Microsoft 365 or Google Workspace configuration, moves your domains to an enforced DMARC policy without breaking legitimate mail, and operates detection and response for email threats — including triaging messages your users report and removing malicious emails from every mailbox they reached.

It works hand-in-hand with our Security Awareness Training and Phishing Simulation services to strengthen the human layer.

Frequently asked questions

Will DMARC enforcement block our legitimate emails?

Not if done in stages. We first monitor to identify every legitimate sender, fix their authentication, and only then enforce.

Do you support Microsoft 365 and Google Workspace?

Yes, both platforms are supported.

How fast can you remove a phishing email from all inboxes?

Once confirmed, malicious messages can typically be purged across the organisation within minutes using platform tooling.
