From edge firewalls to business-critical applications and web browsers, attackers are actively exploiting zero-day vulnerabilities across the digital ecosystem. This week, three high-severity threats have surfaced, exposing core systems to remote code execution and full compromise. Organizations must act quickly to mitigate these risks and secure exposed infrastructure.
What is the Phishing-Prone Percentage (PPP)?
The Phishing-Prone Percentage (PPP) is the percentage of users who clicked on a simulated phishing email during testing. It reflects how vulnerable your employees are to phishing before any training.
In the 2025 benchmarking study, KnowBe4 analyzed simulation results across:
- 19 different industry sectors
- 9 geographic regions
- 3 company size categories
The findings deliver critical insight into how susceptible specific verticals are, and how well training programs actually work.
Initial Phishing Risk in 2025: Benchmarking by Industry
The average baseline PPP across all industries was 34.3 percent, meaning over one in three employees clicked on a phishing link without training. But some industries performed significantly worse.
Industries with the Highest Initial PPPs:
- Hospitality – 52.9%
- Education – 50.2%
- Pharmaceuticals – 48.2%
- Healthcare & Medical – 46.9%
- Energy & Utilities – 45.8%
These sectors are high-risk due to sensitive data, high employee turnover, or frequent external communication, all factors that increase phishing vulnerability.
Industries with the Lowest Initial PPPs:
- Technology – 28.5%
- Finance & Banking – 29.8%
- Insurance – 30.1%
Organizations in these industries tend to have more mature cybersecurity programs and stricter access controls.
Phishing Risk by Company Size
Company size plays a role in phishing vulnerability, but not in the way many expect:
- Small organizations (1–249 employees): More vulnerable due to limited resources
- Mid-sized organizations (1,000–2,500 employees): Highest average PPP across the board
- Large enterprises (10,000+ employees): Lower PPPs thanks to stronger governance and layered defenses
Regardless of size, no organization is immune, especially without ongoing training.

Training Works: How PPP Drops Over Time
The most impactful takeaway from KnowBe4’s 2025 report? Security awareness training works, fast and sustainably.
Organizations that implemented consistent phishing simulations and training saw a massive drop in PPP:
| Timeline After Training | Average PPP |
|---|---|
| Initial Baseline | 34.3% |
| After 90 Days | 17.2% |
| After 12 Months | 4.6% |
That’s an 86 percent reduction in phishing vulnerability over one year.
Phishing Tactics: What Lures Are Employees Falling For?
KnowBe4’s simulations use real-world phishing templates designed to mimic what attackers actually send. The most effective lures in 2025 include:
- IT alerts: “Password expired. Click here to reset.”
- Delivery notifications: “FedEx: Your package is delayed.”
- HR notices: “Policy update: View changes to PTO benefits.”
- Account security warnings: “Suspicious login detected.”
These messages rely on urgency, fear, or curiosity, triggering emotional responses before critical thinking kicks in.
How to Reduce Phishing Risk in Your Organization
Based on the 2025 benchmark data, here are the most effective strategies for reducing phishing exposure:
- Invest in Security Awareness Training: Train employees continuously, not just once a year. Tailor content by department and role.
- Launch Ongoing Phishing Simulations: Test your workforce with simulated phishing campaigns. Use results to identify high-risk users.
- Measure Your Own PPP and Benchmark It: Compare your phishing-prone rate against KnowBe4’s industry averages to assess your risk.
- Layer Technical Controls: Use secure email gateway, DNS filtering, and multi-factor authentication to block phishing payloads.
- Build a Security-First Culture: Reward users for reporting suspicious emails and normalize asking IT for help.
In Closing: Understand the Risk, Train to Prevent It
The Phishing by Industry Benchmarking Report 2025 underscores a hard truth: technical defenses alone aren’t enough. People are the last line of defense, and often the first target.
The most at-risk industries in 2025 are those that interact with sensitive data, the public, or third-party vendors. But no sector is truly safe without training.
