How to Prevent Phishing Attacks at Work

by Gloria Bakerian | Jun 16, 2025 | Cybersecurity

Learn how to prevent phishing attacks at work before someone clicks the wrong link.

Phishing scams are not going away any time soon, and they’re getting more and more difficult to spot. Today’s phishing emails are clean, convincing, and often disguised as messages from trusted contacts or vendors. One click can compromise credentials, leak financial data, or bring down your systems.

For small and mid-sized businesses, prevention starts with awareness. Here’s how to prevent phishing attacks at work before someone on your team clicks something they shouldn’t.

Phishing protection starts with awareness. Discover tools and tips for training your team.

PCC helps businesses prevent phishing attacks with training, tools, and support.

1. Teach Employees How Phishing Actually Works

If your team still thinks phishing emails are full of typos and far-fetched stories, it’s time for a reality check. Modern phishing attacks are sophisticated and carefully designed to fool even savvy users.

Use real examples in training. We’ve shared some here:

➡️ The Danger Behind Display Names: Email Spoofing Explained

💡 Did You Know?
Companies that train employees using real-life phishing examples reduce their click-through rate by up to 75%. That’s how you prevent phishing attacks through education, not guesswork.

2. Run Simulated Phishing Tests

Practice builds confidence. Simulated phishing campaigns help employees recognize threats in a safe environment and improve their response time. More importantly, they reveal who might need additional training before a real attack hits.

At PCC, we offer ongoing phishing simulations as part of our managed IT services. Not just one-time tests, but a consistent program to build long-term awareness.

3. Enable Multi-Factor Authentication (MFA)

Even if someone accidentally clicks a phishing link and enters their password, MFA adds a second layer of defense. It is one of the simplest and most effective tools to stop unauthorized access.

If you haven’t already implemented MFA across email, cloud storage, CRMs, and financial systems, now is the time.

We’re working on a full blog about MFA soon. Let us know if you’d like a preview or help getting started.

4. Use DNS Filtering and Email Protection Tools

Phishing often includes more than just a fake email. It may involve malicious links, infected attachments, or redirects to credential-harvesting sites.

At Professional Computer Concepts, we block these threats before they reach your inbox using tools like:

  • DNS Filtering to prevent users from visiting malicious sites

  • SPF, DKIM, and DMARC to stop email spoofing

  • Ongoing security awareness training tailored to your team

We don’t just deploy tools and move on. We stay involved with continuous monitoring, updates, and adjustments as threats evolve.

5. Build a Cyber-Aware Culture

The best defense against phishing is your people. Encourage your team to slow down, question unexpected emails, and report anything suspicious. Recognize those who flag real threats. Make security awareness part of your culture, not a one-time event.

💡 Did You Know?
One in every 99 emails is a phishing attempt. Without ongoing training and proper safeguards, it’s only a matter of time before someone clicks.
