Email Is Still the #1 Way Hackers Get In — Here’s What Actually Stops It
Ransomware, data breaches, wire fraud — almost all of it starts the same way: someone clicks a link or opens an attachment in an email that looked legitimate enough not to question. Despite years of security awareness training and increasingly sophisticated tools, email remains the single most common entry point for attackers, and it’s not particularly close.
Here’s why basic spam filtering isn’t enough anymore, and what actually closes the gap.
Phishing Has Gotten Much Harder to Spot
The obvious red flags — bad grammar, sketchy links, a “prince” asking for help — mostly belong to an earlier era of phishing. Today’s attacks are polished. Attackers research their targets, mimic real vendors and colleagues convincingly, and increasingly use AI tools to write messages that read exactly like a normal business email. The old advice of “just look for typos” doesn’t hold up the way it used to.
Business Email Compromise Is a Different, More Costly Threat
Beyond generic phishing, Business Email Compromise (BEC) attacks specifically target businesses by impersonating executives, vendors, or partners to redirect payments or extract sensitive information. These attacks often involve no malware or suspicious links at all — just a convincingly worded request from what looks like your CEO or a trusted vendor asking for a wire transfer or a change to payment details. Standard spam filters frequently miss these entirely because there’s nothing technically “malicious” in the email itself.
What Modern Email Security Actually Includes
Advanced threat protection, which goes beyond basic spam filtering to analyze links and attachments in real time, catching threats that don’t match a known signature.
Domain authentication (SPF, DKIM, DMARC), which makes it significantly harder for attackers to spoof your domain and use it to impersonate your business in attacks on your customers or partners.
Impersonation detection, which flags messages designed to look like they’re from an executive or trusted contact, even when the sender’s actual email address doesn’t match.
Ongoing security awareness training — not a single onboarding session, but regular, current training that reflects how phishing tactics are actually evolving right now.
A clear internal process for financial requests, so that a request to change payment details or send a wire transfer always requires verification through a second channel, regardless of how urgent or legitimate the email sounds.
Why “We Have Spam Filtering” Isn’t the Same as “We’re Protected”
Most businesses already have some baseline email security, often bundled into whatever platform they’re using. The problem is that baseline protection is built to catch the obvious stuff — not the convincing, targeted attacks that cause the most damage. The gap between “basic” and “actually protected” is usually smaller and cheaper to close than business owners expect.
At Waypoint Technology Solutions, email security is one of the first things we review in a Business & Technology Assessment, because it’s consistently one of the highest-risk, most overlooked areas we see. If it’s been a while since anyone took a real look at what’s actually protecting your inbox, it’s worth the conversation.
