What we cover
Practical, board-ready consulting — no jargon, no surprise invoices.
DMARC Enforcement
We configure SPF, DKIM, and DMARC to block email spoofing and domain impersonation — the foundation of email security that most UK SMEs lack.
BEC Prevention
We implement controls that stop business email compromise — mailbox rule monitoring, payment-verification workflows, and staff training.
Phishing Protection
We configure Microsoft Defender for Office 365 (or Google Workspace security) to catch phishing before it reaches inboxes — plus simulation training.
Mailbox Compromise Detection
24/7 monitoring for inbox rule creation, external forwarding, suspicious OAuth grants, and impossible-travel sign-ins — the top BEC indicators.
Email Authentication Audit
We audit your SPF, DKIM, DMARC, and MX records — and fix the misconfigurations that let spoofed email through.
Staff Email Training
We train staff to spot phishing and BEC — the human layer that technology can't fully replace. Includes phishing simulation.
How we work
Audit (1 week)
We audit your email configuration — SPF, DKIM, DMARC, mail flow rules, and admin roles. Gaps identified.
Remediation (1-2 weeks)
We enforce DMARC, configure anti-phishing, and deploy mailbox monitoring. Staff training delivered.
Ongoing monitoring (optional)
24/7 mailbox monitoring — catches BEC and compromise within minutes.
Sectors we protect
