Untrained enterprise employees click on simulated phishing links at a baseline rate of 34.3%, but ongoing monthly training drives that vulnerability rate down to 5.4% within 12 months. As explored in our phishing-statistics-2026 and mfa-fatigue-statistics-2026, the human layer remains the primary target for modern cybercrime syndicates seeking initial network entry. The figures below synthesize verified empirical telemetry from the Verizon DBIR, the SANS Security Awareness Report, KnowBe4, and Osterman Research.

1. Baseline Vulnerability and Long-Term Training Efficacy
When organizations launch their first unannounced phishing simulation, more than one in three employees inadvertently click the lure or input credentials. Consistent, interactive micro-learning steadily establishes organizational muscle memory. Credential theft mechanisms are detailed in our account-takeover-statistics-2026.
| Training Maturation Stage | Small Business (<250 Staff) | Mid-Market (250–999 Staff) | Enterprise (1,000+ Staff) | Source |
|---|---|---|---|---|
| Initial Baseline (Untrained) | 35.8% Click Rate | 36.4% Click Rate | 34.3% Click Rate | KnowBe4 Benchmark |

2. Industry Sector Vulnerability and Departmental Risk
Employees tasked with opening unsolicited incoming resumes, vendor invoices, or customer support inquiries are structurally more exposed to sophisticated social engineering lures. Telephony attacks are evaluated in our vishing-statistics-2026.
| Industry Sector | Baseline Phish-Prone % | 12-Month Post-Training % | Most Effective Simulation Lure | Source |
|---|---|---|---|---|
| Healthcare & Life Sciences | 39.8% | 6.2% | HIPAA compliance / Benefit update | KnowBe4 Benchmark |
| Education & Universities | 38.2% | 7.1% | Password reset / Shared drive link | SANS Report |
| Retail & Hospitality | 36.5% | 5.8% | Holiday schedule / Gift card promo | Osterman Research |
| Financial Services & Banking | 31.4% | 4.1% | Wire transfer / Corporate audit | KnowBe4 Benchmark |
| Technology & Software | 29.8% | 3.8% | Cloud IT ticket / Zoom update | SANS Report |
| Government & Public Sector | 34.0% | 5.2% | Civil service policy update | Verizon DBIR |

3. Human Risk Distribution and The “Repeat Clicker” Problem
Enterprise risk is not distributed evenly across the workforce. A small cohort of repeat clickers generates a disproportionate share of simulated and actual security failures. Password habits are explored in our password-security-statistics-2026.
| Employee Risk Profile | Share of Corporate Workforce | Share of Total Simulation Clicks | Mandatory Remediation Protocol | Source |
|---|---|---|---|---|
| Consistent Reporters (Zero Clicks) | 54.2% | 0.0% | Gamified reward / Digital badge | SANS Report |
| Occasional Clickers (1 Failure) | 26.8% | 22.4% | Automated 5-min refresher module | KnowBe4 Benchmark |
| Moderate Risk (2 Failures) | 10.6% | 31.2% | Manager notification + 30-min course | Osterman Research |
| Chronic Repeat Clickers (3+ Failures) | 8.4% | 46.4% | In-person coaching / Access review | SANS Report |

4. Economic ROI and Breach Containment Cost Benefits
Measuring the tangible financial value of security awareness programs relies on quantifying averted breach incidents, decreased endpoint re-imaging tickets, and accelerated SOC response times.
| Cost Avoidance Metric | Untrained Organization | Fully Trained Organization | Annual Net Savings ($10K Seats) | Source |
|---|---|---|---|---|
| Average Phishing Incident Containment | $284,000 | $92,000 | $1,920,000 (Averted Breaches) | Ponemon Institute |
| Helpdesk Malware Cleanup Tickets | 142 Tickets / Mo | 24 Tickets / Mo | $118,000 (Saved IT Labor) | Osterman Research |
| Employee Productivity Loss per Phish | 4.8 Hours | 0.8 Hours | $420,000 (Productivity) | SANS Institute |
| Net Program ROI per Seat | N/A | $562 per Seat | $5,620,000 Total Value | Ponemon / SANS |

5. Modern AI Threats and Simulated Testing Sophistication
The deployment of Large Language Models (LLMs) by cybercrime syndicates has rendered traditional training advice (“look for typos and grammatical errors”) obsolete, necessitating AI-resistant training modules. Remote work challenges are detailed in our remote-work-statistics-2026.
| Simulation Lure Type | Click Rate (Untrained) | Click Rate (Trained) | Credential Entry Rate | Source |
|---|---|---|---|---|
| Standard Generic Template (Grammar Flaws) | 22.4% | 2.1% | 0.8% | KnowBe4 Benchmark |
| Brand Impersonation (Microsoft/Google) | 36.8% | 5.4% | 2.8% | KnowBe4 Benchmark |
| Generative AI Tailored Spear Phishing | 48.2% | 11.2% | 6.4% | SANS Report |

Methodology and Sources
Data in this benchmark is compiled from millions of simulated phishing emails tracked across tens of thousands of corporate organizations in the KnowBe4 Phishing By Industry Benchmark, empirical breach forensic investigations documented in the Verizon Data Breach Investigations Report (DBIR), security leadership surveys from the SANS Security Awareness Report, and economic impact analyses from the Ponemon Institute and Osterman Research.

Data watch: Simulation telemetry measures employee interactions with controlled enterprise tests conducted under authorization. Actual criminal spear-phishing attack success rates can be higher during active emergencies or major organizational transitions when attackers leverage stolen vendor email threads (BEC) rather than standalone synthetic lures.
