Email Security: The Simple Fix That Most Firms Overlook

June 12, 20252 min read

If you think your firm’s email is secure, you’re not alone.
But here’s the uncomfortable truth: most small and midsize businesses are missing basic email protections — and they don’t even realize it.

That’s a problem, because over 90% of cyberattacks start with email.
And the latest wave of attacks? It’s not just spam — it’s impersonation.

We’re talking about:

  • Fake emails that look like they’re from your managing partner

  • Spoofed invoices that appear to come from your vendors

  • Client requests that seem legit, but aren’t

The goal? Trick someone into clicking a link, downloading a file, or wiring money.

And if your email domain isn’t properly secured, these messages can appear completely legitimate — even to a careful employee.


Three Simple Safeguards That Stop Most Threats

There are three key technologies that work together to protect your email domain from being spoofed:

✅ SPF (Sender Policy Framework)

Think of SPF like a guest list. It tells the internet which servers are allowed to send email on your behalf. Without it, anyone can pretend to be you.

✅ DKIM (DomainKeys Identified Mail)

DKIM adds a digital signature to every email your firm sends. It’s like sealing an envelope — proving the message hasn’t been tampered with along the way.

✅ DMARC (Domain-based Message Authentication, Reporting & Conformance)

This is the rule-set (and the bouncer) that tells receiving servers what to do if an email fails SPF or DKIM checks. Should it be blocked? Flagged? Reported?

Together, these three safeguards make it much harder for attackers to spoof your domain.


So… Is Your Domain Protected?

Here’s the kicker: many firms assume these protections are already in place.
But we regularly run audits and find:

  • SPF records that are incomplete or misconfigured

  • DKIM not set up at all

  • DMARC policies missing or left in “monitor” mode permanently

These aren’t unusual cases — they’re common.
