Vulnerability Scans in Action

The Hacker's Eye View

In the pre-bind phase, insurers utilize external vulnerability scans—often called 'outside-in' scans—to see exactly what a hacker sees. These scans map an organization's digital perimeter, focusing on public-facing assets like websites, email servers, and VPN gateways.

Welcome to this exploration of how vulnerability scans transform the underwriting process. Imagine your organization as a fortress. Traditional questionnaires ask if the gates are locked, but an 'outside-in' scan actually walks the perimeter to check for open windows. This provides a complementary view to questionnaires, focusing on how security controls are operating in practice rather than just how they are designed.

• Scans provide a 'hacker’s eye view' of the organization’s perimeter.
• They complement traditional questionnaires by showing real-world security performance.
• As noted in Gallagher’s Cyber IQ Report, these scans validate if security controls are actually operating.

Identifying Underwriting 'Red Flags'

Underwriters look for specific red flags that indicate high risk. Identifying these early allows for remediation before binding.

Underwriters focus on three critical areas during a scan. First, open Remote Desktop Protocol ports. According to Coalition’s 2025 Cyber Threat Index, these remain a top entry point for ransomware. Second, they look for unpatched perimeter devices like firewalls. A critical vulnerability here can lead to an immediate 'decline to quote'. Finally, they look at the overall risk score. A grade of 'C' or lower often triggers higher premiums or restrictive limits. RDP should never be exposed directly to the internet. It is the 'open door' hackers love most. Perimeter devices are your first line of defense. If they are unpatched, the entire network is at risk.

• Open RDP ports are a top entry point for ransomware (Coalition’s 2025 Cyber Threat Index).
• Unpatched firewalls/VPNs can lead to an immediate 'decline to quote'.
• Letter grades (A-F) impact premiums and coverage sub-limits.

Deciphering Subjectivities

When a scan reveals a critical issue, the underwriter issues a subjectivity. This is a condition that must be met before the policy can be bound.

Think of a subjectivity as a 'fix-it' ticket for your insurance. The carrier may offer a quote, but coverage is 'subject to' specific actions. If you ignore these, you risk facing higher premiums, lower limits, or even a total exclusion of coverage for that specific vulnerability.

• Subjectivities are remediation requirements.
• Ignoring them leads to higher premiums or exclusions.
• Successful remediation secures better terms.

Scenario: The Retailer’s Redemption

A mid-sized retailer faces a 20% surcharge due to a critical VPN vulnerability. Help the broker navigate the risk portal to secure a better rate.

First, use the carrier's risk portal to show the client the exact technical finding. The client patches the vulnerability within 48 hours. Finally, provide proof of remediation. The underwriter now issues the policy at the preferred rate! Let's put this into practice with a retail scenario. The carrier found a critical vulnerability on the client's VPN. Without action, they face a heavy surcharge. Click the steps to resolve the issue.

• Use risk portals to identify the exact issue.
• Rapid remediation (within 48 hours) can avoid surcharges.
• Proof of remediation leads to preferred rates.

Prioritization Workflow

When a scan report arrives, don't panic. Use this prioritization workflow to handle the data efficiently.

Scan reports can be overwhelming. Follow this four-step workflow to clean up the report and secure the best terms for your client. Always start by filtering for Critical and High severity items. These are the deal-breakers. Finally, request a re-scan. This proactive step signals high security maturity to the underwriter. Next, validate the asset. Is it a decommissioned server? If so, it's a false positive that can be removed. If you can't patch, document your compensating controls, like placing the server behind a strict firewall.

• Filter by severity (Critical/High) first.
• Validate assets to remove false positives.
• Document compensating controls if patching isn't possible.
• Request a re-scan to signal security maturity.

Scenario: The RDP Roadblock

A manufacturing firm has an open RDP port. Help them navigate the remediation workflow to secure their $5M policy.

First, the IT team must close Port 3389. This immediately reduces the attack surface. Next, they must verify Multi-Factor Authentication on all remote points. This adds a vital layer of security. Finally, the broker requests a re-scan. With a clean report, the underwriter removes the subjectivity and drops the premium by 10%! A client is stuck. The carrier found an open RDP port on a legacy server. Walk through the steps to remove this roadblock and secure a lower premium.

• Identify the specific port (3389).
• Implement MFA for remote access.
• Request a re-scan to clear the subjectivity.

Prioritizing Remediation

You've received a scan report with various findings. In 2-3 sentences, explain which findings you would prioritize and why.

Efficiency is key in the pre-bind phase. Look at this list of findings. Type your plan for which ones to tackle first to ensure the policy binds on time.

• Focus on 'Critical' and 'High' risks.
• Underwriters rarely hold up binds for 'Low' risks.
• Criticals are often deal-breakers.

Case Study: The Underwriter's Decision

Review the scan results for 'Global Logistics' and decide how to advise them to ensure they avoid a premium surcharge.

Global Logistics has received a scan with three findings. Analyze the findings and type a brief 2-sentence recommendation to the client on what they must do first and why. Focus on the impact on their policy terms.

• Identify deal-breaking vulnerabilities.
• Formulate a remediation strategy.

The 'Point-in-Time' Trap

A clean scan today does not guarantee security tomorrow. Avoid the point-in-time trap by treating security as a continuous process.

The biggest pitfall is treating a scan as a one-and-done task. New vulnerabilities emerge every day. Furthermore, scans often uncover 'Shadow IT'—servers or sites your IT team forgot existed. Treat these forgotten assets with the same priority as your main website.

• Vulnerabilities emerge daily.
• Shadow IT (forgotten assets) must be managed.
• Continuous monitoring is the gold standard.
