"First class service, dealt with upgrading our email security for DMARC as professionally as I have ever come across".
"People don't usually think about email security until something goes wrong. Sendmarc works quietly in the background and does exactly what it's supposed to. "
"With the Central Bank breathing down our necks about cyber security we needed to ensure our email communications with our members were 100% secure, moving to Sendmarc to lock this down became a need to have rather than a nice to have. With a fully supported, managed integration we now feel confident any email reaching our members remains genuine. We have been so impressed with the service and support we have had from the team so far".
"We needed 100% email security for cyber insurance, NIS2 and ISO27001 purposes. Delighted to recommend BeSecureOnline and Sendmarc for DMARC security. Installation was painless — and helped us to secure premium cyber insurance renewal premium reductions."
This is the number one fear for any IT lead — and the question that kills more DMARC projects than anything else.
Implementing DMARC will not disrupt your email if it is done correctly. We start every implementation in monitoring mode (p=none), which means zero impact on your mail flow. We map every sending source — your Microsoft 365, third-party apps, marketing tools — before a single enforcement policy is applied. Only when we are 100% confident does anything change. Our clients reach p=reject in under 90 days with no disruption to legitimate email.
Yes — and the pressure is coming from multiple directions simultaneously.
UK Government — Public Sector:
The Cabinet Office Securing Government Email policy (gov.uk/guidance/securing-government-email) mandates DMARC, SPF, and DKIM as a legal must-do for all public sector organisations running internet-facing email. This applies to central government departments, local councils, state bodies, health authorities, the HSE, county councils, and any organisation receiving public or exchequer funding. Enforcing DMARC on inbound email and conducting regular reporting are both explicitly required — not recommended.
Cyber Insurance:
Most UK and Irish insurers now require DMARC at p=reject as a condition of underwriting. If your organisation cannot demonstrate enforcement, expect either a declined renewal or a significantly increased premium.
NIS2 Directive:
Applicable to organisations in Ireland and the EU operating in essential or important sectors. Email authentication is a core technical control under the directive’s security requirements.
ISO 27001:2022:
Annex A communications security controls (A.13) now explicitly reference SPF, DKIM, and DMARC as required technical measures to prevent spoofing and protect information in transit.
PCI DSS v4.0:
Mandatory since March 2025 for any organisation handling payment card data.
Microsoft (May 2025):
Bulk senders without DMARC authentication now face outright rejection from Microsoft’s consumer mail services.
If your organisation touches any of these — and most do — this is no longer a discretionary project.

Think of them as three layers of the same lock.
SPF confirms which servers are authorised to send email on your behalf.
DKIM adds a digital signature to every outgoing message, proving it has not been tampered with in transit.
DMARC ties both together and tells receiving mail servers what to do with emails that fail — monitor, quarantine, or reject.
You need all three. SPF or DKIM alone will not stop domain spoofing. DMARC at p=reject is the only policy that actively blocks fraudulent emails from reaching your customers, partners, and staff. Over 80% of domains still have no enforcing DMARC policy — leaving them wide open to impersonation.
With BeSecureOnline and Sendmarc, our clients reach p=reject in under 90 days.
| Phase | Timeline | What We Do |
|---|---|---|
| Phase 1 — Discovery & Monitoring | Weeks 1–2 | Map all sending sources, deploy p=none |
| Phase 2 — SPF & DKIM Alignment | Weeks 3–6 | Fix misconfigurations, authorise third parties |
| Phase 3 — Quarantine | Weeks 7–10 | Ramp enforcement gradually |
Phase 4 — Full p=reject | By week 12 | Complete protection, BIMI branding eligible |
Doing this without a managed service typically takes 6–12 months. We compress that timeline because we have done it for hundreds of organisations before yours.
Yes — and they solve entirely different problems.
Your email gateway (Hornetsecurity, Proofpoint, Mimecast etc.) protects your inbound email — filtering spam, malware, and phishing coming into your organisation.
DMARC protects your outbound sending reputation — it stops cybercriminals from sending fraudulent emails that appear to come from your domain to your clients, suppliers, and staff elsewhere. Your gateway does nothing to prevent that. DMARC, SPF, and DKIM are the only controls that do.
“With the Central Bank breathing down our necks about cyber security, we needed to ensure our email communications with our members were 100% secure. Moving to Sendmarc to lock this down became a need to have rather than a must have. With a fully supported, managed integration we now feel confident any email reaching our members remains genuine. We have been so impressed with the service and support we have had from the team so far.”

BIMI — Brand Indicators for Message Identification — is the reward you unlock once your DMARC implementation reaches full enforcement at p=reject. It places your organisation’s verified, trademarked logo directly next to your emails in supported inboxes including Gmail, Apple Mail, Yahoo, and Outlook. Think of it as a blue tick for your email.
The results speak for themselves:
– Up to 38% higher open rates
– 90% increase in consumer confidence in email legitimacy (UK)
– Up to 120% improvement in brand recall
– 32% trust score uplift

BIMI turns a security compliance project into a brand visibility win — which is why it resonates well beyond the IT department:
For Marketing Directors:
Your logo appears in every recipient’s inbox before the email is even opened. Zero ad spend required.
For CEOs and Chairpersons:
Your brand is visibly verified and protected at every send — a powerful signal of trust to customers and partners.
For CISOs and IT Leads:
BIMI is only achievable at p=reject. It validates and rewards your full DMARC implementation, giving the board a tangible, visible outcome to point to.
What it requires is DMARC at p=reject plus a Verified Mark Certificate (VMC) for your registered trademark. BeSecureOnline handles both as part of a fully managed implementation — so your team carries none of the technical burden.
