Protect your brand, protect your customers, protect your revenue.
We lock down your domain so nobody can send as you, make sure your real emails actually get delivered, and turn your brand's inbox presence into an asset instead of a liability.
Why This Matters
Email fraud is the single largest category of reported cybercrime loss — the FBI logged $2.9 billion in Business Email Compromise losses in 2023 alone. These attacks don't need malware or a hacked network; they just need your brand to look convincing in someone's inbox.
If your domain isn't properly authenticated, anyone can attempt to send as you — and your own legitimate emails can start failing to arrive. We close that door without changing how your business operates day to day.

Full Email & DNS Security Services
Assessment & Visibility
DNS Threat Assessment & Risk Mitigation
Find out exactly what's exposed before anyone else does. A full audit of your domain's email authentication, sending sources, and DNS security posture — with a clear, prioritised list of what to fix and why.
Legacy Third-Party Sender Assessment
Old CRMs, abandoned marketing tools, decommissioned servers — if they were ever authorised to send email as you, they may still be able to. We find every legacy sender still hiding in your DNS records.
DKIM Assessment
We check whether your DKIM signing is actually configured correctly — key strength, selector hygiene, alignment — because a broken DKIM setup often looks fine until deliverability quietly drops.
Mail Estate Hardening & Compromise Detection
Authentication stops spoofing. It doesn't stop a genuinely compromised mailbox. We assess and harden your real mail estate against the signs of account takeover — inbox rule abuse, rogue forwarding, unexpected MFA changes.
Authentication & Anti-Spoofing
SPF Flattening
SPF has a hard 10-lookup limit. Connect more than that (Outlook, Mailchimp, your CRM, a helpdesk tool) and legitimate email can silently start failing. We flatten every nested lookup into fixed IP addresses so your SPF record never breaks again — managed as an ongoing service.
DMARC & DMARCbis Implementation
Full DMARC deployment and policy management, taking you from monitoring to full enforcement safely — plus alignment with DMARCbis, the newly formalised IETF standard (RFC 9989/9990/9991) published in 2026.
DKIM Implementation & Key Rotation
We set up DKIM properly — and, unlike almost everyone else, we manage the ongoing key rotation policy most companies have never even considered. A key that's never rotated is a bigger, longer-lived target.
BIMI Setup
Your logo, next to your name, in your customer's inbox. BIMI puts your verified brand mark directly in supported inboxes — turning your DMARC enforcement into visible brand value, not just a security control.
Transport & Infrastructure Security
MTA-STS Implementation
Enforces encrypted delivery for mail travelling to and from your domain, closing interception and downgrade risks that authentication alone doesn't cover.
TLS Reporting (TLS-RPT)
Visibility into failed delivery attempts you'd otherwise never see — catching infrastructure problems before they become real deliverability failures.
DANE
DNSSEC-backed certificate binding for mail transport — an extra layer of verifiable trust for partners and sectors that specifically require it.
TLS Configuration & HSM-Backed Certificate Management
Hardware-backed key protection and centralised certificate management, so an expiring cert or a compromised server never causes an outage or an exposure.
Compliance & Migration
NCSC Mandatory Configuration Standards Compliance
The NCSC retired its free Mail Check and Web Check tools in March 2026 — leaving UK public sector and regulated organisations without the free monitoring they used to rely on. We provide the ongoing DMARC, SPF, DKIM, and TLS verification needed to stay compliant with the UK Minimum Cyber Security Standard.
Hybrid Exchange & Microsoft Migration Support
Moving from on-premise Exchange to hybrid or fully online is notoriously difficult, and Microsoft's own tooling doesn't make it easy. Our email experts apply deep hands-on Microsoft messaging experience to your migration — done properly, without the outages.
Deep Email Expertise
Email security is one of our deepest specialisms — our experts live inside messaging systems, Exchange, hybrid environments, migrations, authentication, and all the edge cases that come with them.
