Understanding Vulnerability Scans in Cybersecurity
In today’s digital world, vulnerability scans are no longer optional—they’re essential.
Every business that relies on websites, servers, or cloud applications faces security risks, and a vulnerability scan is one of the most effective ways to detect those risks before hackers exploit them.
On the HIPAA Insider Show from HIPAA Vault, host Adam Zenedine introduced the topic by saying:
“We’re not talking about X-rays or MRIs. We’re talking about scans that look for vulnerabilities in your systems, websites, or applications.”

Whether you’re in healthcare, finance, e-commerce, or simply managing IT infrastructure, understanding vulnerability scans can help you stay secure, compliant, and resilient. If you’re looking for managed HIPAA hosting and compliance services, check out our HIPAA Compliant Cloud Hosting.
Everything You Need to Know About Vulnerability Scans
A vulnerability scan is an automated security assessment that checks your applications, servers, or networks for known weaknesses.
These scans identify misconfigurations, outdated software, open ports, and other flaws that attackers could exploit.
Henri Alfonso, compliance manager at HIPAA Vault, explained it clearly:
“Security is usually forgotten during development and considered last minute. That’s always bad. You should include it at each step.”
👉 If you’re unsure whether your infrastructure is secure, request a vulnerability scan today to see exactly what’s exposed.
Why Vulnerability Scans Are Critical for Cybersecurity and Compliance
Cybersecurity threats are constantly evolving. Without scanning, your business could unknowingly expose critical data.
Key reasons vulnerability scans are important:
- Prevent Data Breaches – Detect weaknesses before attackers exploit them.
- Meet Compliance Standards – Strongly recommended by HIPAA, PCI-DSS, GDPR.
- Improve Risk Management – Classify vulnerabilities by severity.
- Support IT Teams – Provide actionable remediation steps.
Skipping scans is like leaving your office doors unlocked at night—you may not see immediate harm, but the risk is real.
Different Types of Vulnerability Scans and How to Choose
Not all scans are created equal. Businesses often confuse them, but choosing the right type is critical.
1. URL-Based / Unauthenticated Scans
“The free surface-level URL scan shows what you’re exposing to the world. It’s a great first step.”
— Adam Zenedine, HIPAA Insider Show
- Run against a public-facing website or server.
- Show what an attacker sees without login credentials.
- Great for quick visibility, limited in scope.
2. Credentialed / Authenticated Scans
“With a credentialed scan, our scanner logs in as a user. It gives a full idea of what is exposed on your system.”
— Henri Alfonso, HIPAA Vault
- Use valid login credentials.
- Simulate an attacker who gains access.
- Detect insecure configurations, outdated software, and hidden issues.
3. Web Application Penetration Tests
“Penetration testing goes above a credential scan. It tries to break your application and automates malicious activities.”
— Henri Alfonso, HIPAA Vault
- Actively attempt to exploit vulnerabilities.
- Go beyond scanning to simulate real-world hacker activity.
- Required in some industries (like DoD contracts), but optional for HIPAA.

Quick Comparison Table
| Scan Type | Access Level | Purpose | Depth of Results |
| URL/Unauthenticated | Public only | Surface-level vulnerabilities | Low |
| Credentialed | User-level access | Internal risks, outdated software, configs | High |
| Pen Test | Exploitation attempt | Simulated hacker attack | Very High |
Free Vulnerability Scans: What They Can and Can’t Do
“Our free scan shows you what you’re showing everyone else out there on the internet, just to give you an idea of how we can help.”
— Henri Alfonso, HIPAA Vault
Free scans are a great starting point but limited. They usually:
- Highlight exposed ports.
- Detect outdated public-facing software.
- Provide a basic overview of risks.
But they won’t detect internal misconfigurations or simulate insider threats.

Credentialed Vulnerability Scans: A Deeper Look
“The scan tells you what software is installed, what version it is, and any configurations that might be exploitable.”
— Henri Alfonso, HIPAA Vault
Credentialed scans dig much deeper. By logging in with valid credentials, they analyze the full environment.
They detect:
- Installed software versions.
- Weak configurations.
- Encryption flaws.
- Services exposed internally.
This makes credentialed scans the best option for businesses that want a true picture of their cybersecurity health.
Vulnerability Scans vs Penetration Testing: Key Differences
“The penetration test is not really a scan—it goes into the nitty-gritty of your application’s code.”
— Adam Zenedine, HIPAA Insider Show
It’s easy to confuse penetration testing with vulnerability scans.
- Vulnerability Scan = Detection. Identifies risks and lists them.
- Penetration Test = Exploitation. Attempts to prove risks by exploiting them.
Both are valuable, but vulnerability scans are the first defense line, while pen tests are deeper audits for compliance or high-security environments.

How to Read and Understand a Vulnerability Scan Report
“The report breaks down vulnerabilities into critical, severe, or moderate. Executives usually stop at the summary, while IT teams dig deeper.”
— Henri Alfonso, HIPAA Vault
Most reports include:
- Executive Summary – How secure your organization is at a glance.
- Technical Breakdown – Details of vulnerabilities, affected hosts, ports, and remediation steps.
As Adam added:
“Executives just want to know: how good are we, how bad are we?”
Common Vulnerabilities Found During Scans
Some of the most common issues revealed by vulnerability scans include:
- Open ports that allow unauthorized entry.
- Outdated Apache or PHP versions.
- Weak SSL/TLS encryption.
- Misconfigured firewalls.
- Unpatched operating systems.
These map closely to the OWASP Top 10 security risks.
Steps to Take After a Vulnerability Scan
Running a scan isn’t enough—you need to act.
Steps:
- Prioritize critical risks first.
- Assign tasks to IT/security staff.
- Apply patches and fixes.
- Re-scan to confirm remediation.
Without follow-up action, scanning alone provides no protection.
Best Practices for Regular Vulnerability Scanning
“Even a high-level uncredentialed scan can provide insight, but you should always scan throughout development.”
— Henri Alfonso, HIPAA Vault
To maximize effectiveness:
- Scan regularly (monthly or quarterly).
- Integrate into DevOps pipelines for early detection.
- Combine with monitoring tools (SIEM, IDS).
- Maintain documentation for audits.
NIST recommends regular vulnerability management as part of a complete cybersecurity program (NIST SP 800-40).
Choosing the Right Type of Scan for Your Business
The right scan depends on:
- Compliance needs (HIPAA, PCI-DSS).
- Budget (free vs enterprise tools).
- Environment (cloud vs on-prem).
Small businesses can start with free or credentialed scans. Larger enterprises should implement all three, including regular pen tests.

HIPAA Compliance and the Role of Vulnerability Scans
HIPAA doesn’t require penetration testing directly, but it does mandate risk analyses and protection of ePHI (electronic Protected Health Information).
Vulnerability scans are a practical way to demonstrate due diligence and meet HIPAA’s Security Rule.

Conclusion: Making Vulnerability Scans Part of Your Security Strategy
“It’s not just technical jargon. A scan gives you a roadmap—what’s wrong, and how to fix it.”
— Adam Zenedine, HIPAA Insider Show
Vulnerability scans are your cybersecurity health checkup. They:
- Detect risks early.
- Provide remediation steps.
- Support compliance efforts.
The next step is clear: schedule your first scan and make it part of a continuous security process.
