Quick Take

Email is the #1 entry point for cyberattacks — from phishing and fake invoices to hijacked accounts. Most breaches start with a single click. This post breaks down the real-world risks and practical steps every business can take to keep their inbox (and data) safe.

Why Email Security Matters

Email is still the backbone of business communication — but also a hacker’s favorite target. Every message you receive is a potential doorway into your company.

Cybercriminals know it’s easier to trick a person than to break into a server. That’s why phishing emails remain one of the most common ways businesses are compromised.

Phishing: The Hook That Catches Businesses

Phishing (spelled with a ph) is when a bad actor pretends to be a legitimate sender — like Amazon, UPS, or your bank — to trick you into clicking a link or downloading an attachment.

That click can install malware, keyloggers, or remote-access tools that let hackers into your systems. Some emails look so real they copy legitimate logos, language, and branding.

And once you enter your “current password” on a fake reset page, you’ve handed over the keys.

How to Spot and Stop Phishing

  • Check the sender’s address – does it really come from who it says it does?

  • Look for red flags – urgent wording, misspellings, or “click here now” prompts.

  • Verify through another channel – call the company directly if unsure.

  • Use AI-powered protection – platforms like Graphus scan headers and origins to detect spoofed messages.

  • Report suspicious emails – don’t just delete them; flag them as phishing.

Smart Filtering and AI Defense

At Slick Cyber Systems, we use Graphus, an AI-driven email protection platform for Microsoft 365 and Google Workspace.

Here’s how it works:

  • It analyzes the originating IP and header data of incoming emails.

  • If it sees something unusual, it flags the message before it reaches your inbox.

  • Dangerous messages are quarantined automatically.

  • For questionable messages, it adds a warning banner so users can double-check before clicking.

Pro Tip: If your email platform doesn’t offer AI phishing protection, you’re depending entirely on human judgment — and even smart people click on bad links.

Why Business Email Should Never Be “Free”

Still using a Gmail or Yahoo account for business? Stop.
Free email accounts don’t have the same security layers, compliance controls, or monitoring that business-class email does.

Even if you don’t have a website yet, set up your own domain — e.g., [email protected]. It adds credibility and keeps your brand (and clients) safer.

Employee Training: The Human Firewall

Technology can filter junk, but the human element remains the weakest link — and the strongest defense.

Cybersecurity awareness training should teach employees to:

  • Spot fake invoices or unusual sender addresses.

  • Think before clicking links or attachments.

  • Verify changes in payment or wire requests.

  • Report suspicious emails immediately.

At Slick Cyber Systems, we deliver automated phishing simulations and short video trainings for our clients. These simulated attacks teach teams how to recognize and report scams safely — without real-world consequences.

Managers get a dashboard showing who clicked, who passed, and who needs more training.

“Think about it — you train people to answer phones correctly, but almost no one trains employees to answer emails safely.” — Jim Slick

Encryption: Protecting Sensitive Data in Transit

Most business emails are sent in clear text — unencrypted. That means private data (like PHI, Social Security numbers, or invoices) can be intercepted if you’re not using secure email encryption.

Encryption tools like Identillect scan your message before sending and warn you if it contains sensitive content. If detected, they automatically secure the email or ask if you’d like to encrypt it.

Only authorized recipients can open the message, keeping your communication compliant and secure.

Don’t Forget Backups

Did you know that Microsoft 365 and Google Workspace do not automatically back up your email?

If a user deletes an important thread, it’s gone for good unless you’ve configured a separate backup solution.

Your MSP (like Slick Cyber Systems) can set up continuous cloud backups for Exchange, OneDrive, and Gmail to ensure your critical messages are never lost.

Key Takeaways

  1. Phishing is the #1 way hackers get in.
    Train your team, use AI-powered filters, and report suspicious messages.

  2. Business email must be business-grade.
    Free accounts put your company at unnecessary risk.

  3. Train your people like you train your phone staff.
    Cybersecurity awareness should be ongoing, not one-time.

  4. Encrypt sensitive messages.
    If you send client or financial info, encryption isn’t optional — it’s essential.

  5. Back up your inbox.
    Your Microsoft or Google account doesn’t protect against deletions or insider mistakes.
