How We Identify Your Most Vulnerable Human Assets
• BizVuln Team
You can spend a million dollars on firewalls, but a single click from a tired employee can bypass it all. Identifying which departments or roles are at the highest risk is the first step in building a human firewall.
Who Is Most at Risk?
The HR Department
HR professionals have to open resumes and application attachments from complete strangers every single day. This makes them a perfect target. A malicious resume PDF or portfolio link is one of the most reliable malware delivery mechanisms attackers use, precisely because HR staff have a professional obligation to open everything they receive. The MITRE ATT&CK framework catalogs spear-phishing via attachment as one of the most consistently used initial access techniques across all threat actor groups.
Finance and Accounts Payable
Finance teams handle wire transfers and vendor payments, making them the primary target for Business Email Compromise (BEC), also known as CEO Fraud. An attacker impersonating a senior executive and requesting an urgent wire transfer is the single most financially damaging type of cyberattack, with average losses exceeding $120,000 per incident. The Verizon DBIR consistently ranks BEC and social engineering as the leading causes of financial loss in data breach incidents.
New Hires
New employees are eager to make a good impression and may not yet be familiar with your company-specific verification protocols. They are more likely to comply with an unusual request without questioning it, and less likely to know who to report suspicion to. The first 90 days of employment represent a disproportionately high-risk window.
The Test, Do Not Guess Strategy
Simulated phishing tests are not about catching people or punishing staff. They are about identifying where the training gaps are before an attacker does.
If 40% of your finance team clicks a Late Invoice link in a simulated test, you now know exactly where your next training session needs to focus. If a new hire in HR opens every single simulated malicious attachment, that is a specific, actionable data point, not a general concern.
The goal is a data-driven map of human risk across your organization: which departments, which roles, and which individuals need targeted intervention. This approach pairs naturally with a regular security health check to ensure that the habits and protocols your team adopts actually hold up over time.
Conclusion
Technology defends the perimeter. People defend everything else. Knowing where your human vulnerabilities are is the only way to address them systematically. Human risk does not exist in isolation — it intersects directly with the threat posed by unauthorized applications and shadow IT, where well-intentioned employees unknowingly create security gaps. The IBM Cost of a Data Breach Report identifies phishing and compromised credentials as the two most common initial attack vectors, both of which are fundamentally human-layer problems.
