Email Security
That Stops Phishing Cold.
Your team gets dozens of emails a day. Attackers only need one click. Business email compromise is the most common attack facing small businesses - not because your team is careless, but because these attacks look exactly like real business communication.
We stop phishing, invoice fraud, and impersonation attacks before they reach the inbox. Your team focuses on work, not second-guessing every message.

How email attacks actually work
These aren't the obvious spam emails your filter catches. They're designed to fool smart people.
The invoice update
Your accounts payable person gets an email from a vendor you've worked with for years. The email says they've changed banks and need you to update their payment information. The email address looks right. The invoice format matches. The amount is exactly what you'd expect.
The CEO request
An employee in accounting gets an urgent email from the CEO. "I need you to process a wire transfer for a confidential acquisition. Time-sensitive. Don't mention this to anyone else." The email looks legitimate. It's the CEO's name, signature, and writing style.
The compromised thread
You're in an ongoing email conversation with a client about a project. Suddenly there's a message in the thread asking for payment to be sent to a "new account." It's in the same thread. Same formatting. Same tone.
The credential harvest
Your team gets an email that looks like it's from Microsoft: "Your password expires in 24 hours. Click here to reset." The page looks exactly like the Microsoft login. Several employees enter their credentials before someone notices the URL is slightly off.

How we protect your inbox
Layers that work together, not just another filter.
1
Stop threats before delivery
Advanced filtering that catches phishing, spoofed domains, and malicious attachments before they reach anyone's inbox. Not basic spam filtering. Real threat detection that understands how modern attacks work.
2
Verify sender identity
We set up SPF, DKIM, and DMARC authentication for your domain. This proves your emails are really from you and makes it much harder for attackers to impersonate your business to your clients and partners.
3
Train your team (for real)
Security awareness training that actually changes behavior. Regular simulated phishing to keep skills sharp. When someone does report a suspicious email, we analyze it so everyone learns from it.
What's included
Advanced threat filtering
Phishing, malware, & BEC detection that goes beyond basic spam filtering. Catches the modern stuff that standard filters miss.
Suspicious email quarantine
Questionable emails held for review instead of delivered. We manage the quarantine so you don't miss legitimate messages.
Reported email analysis
When your team reports something suspicious, we analyze it. If it's a threat, we share what we learned so everyone benefits.
Domain authentication
SPF, DKIM, and DMARC configured properly. Proves your emails are really from you and protects your domain from impersonation.
Email encryption
Policy-based encryption for sensitive messages. Confidential client data and protected health information stay protected.
MFA enforcement
Multi-factor authentication on email accounts. Even if credentials get compromised, attackers can't get in without the second factor.
Questions About Email Security
We know you have questions and we have answers.
-
How much does email security cost?
Email security typically runs $3-8 per user per month depending on the protection level. This is usually bundled with our managed IT services rather than sold standalone. We'll give you exact pricing based on your user count and current setup.
-
We already have Microsoft 365 spam filtering. Isn't that enough?
Microsoft's built-in filtering is decent for spam but limited for sophisticated attacks. BEC emails often contain no malicious links or attachments, just convincing text. They're designed to bypass standard filters. Advanced email security adds layers that catch what Microsoft misses.
-
Can you really stop all phishing emails?
No one can stop 100% of everything. That's why we combine filtering with training. Good filtering catches most threats before delivery. Good training means your team knows what to look for when something gets through. The combination is what works.
-
What's SPF, DKIM, and DMARC?
These are email authentication protocols that prove your emails are really from you. They make it much harder for attackers to send emails that look like they came from your domain. Many businesses have these misconfigured or missing entirely, which makes impersonation easy.
-
How do you handle false positives?
Legitimate emails sometimes get flagged. We manage your quarantine, releasing valid messages quickly. We also tune the filters over time to reduce false positives while maintaining protection. You shouldn't have to dig through a quarantine folder yourself.
-
What's the first step?
We start by looking at your current email setup. What platform are you on? What filtering is already in place? What authentication is configured? From there we can recommend what actually needs to change. Sometimes it's adding layers. Sometimes it's fixing what you already have.
