SOC 2 and Vulnerability Scanning: Do You Actually Need It?

If your company is working toward SOC 2 compliance, you've probably run into the vulnerability scanning question. Some consultants will tell you it's mandatory. Others say it's optional. The real answer is somewhere in between, and it depends on how your auditor interprets the framework.

Here's what we've seen working with organizations going through the process, and what you should actually be thinking about.

A Quick Refresher on SOC 2

SOC 2 comes from the AICPA and sets expectations for how service organizations handle data. If you're a SaaS company or you touch client data in any meaningful way, SOC 2 compliance is probably on your radar (or already a requirement from your customers).

The framework is built around five Trust Services Criteria:

• Security covers protecting system resources from unauthorized access and abuse.
• Availability is about keeping your systems running as promised in your SLAs.
• Processing Integrity means data processing happens correctly, completely, and on time.
• Confidentiality deals with protecting information that's been designated as confidential.
• Privacy focuses on how personal information is collected, used, retained, and disposed of.

Most organizations only scope Security for their first audit, then add criteria as they mature.

What Vulnerability Scanning Actually Does

Vulnerability scanning is automated. You point a tool at your infrastructure (servers, applications, network devices, endpoints) and it looks for known weaknesses. The output is a report ranking those weaknesses by severity so your team knows what to fix first.

This is different from penetration testing. A pen test involves a human actively trying to break into your systems using creativity and chained exploits. Vulnerability scanning is broader but shallower. Both have their place, but they're not interchangeable.

So Is It Required for SOC 2?

Technically, no. SOC 2 doesn't have a line item that says "you must run vulnerability scans." But look at criterion CC7.1 under system operations:

"To meet its objectives, the entity uses detection and monitoring procedures to identify (1) changes to configurations that result in the introduction of new vulnerabilities, and (2) susceptibilities to newly discovered vulnerabilities."

That's a hard requirement to satisfy without some form of automated scanning. You could theoretically meet it through other controls, but most auditors will expect to see scan reports. Vulnerability scanning is listed as a "point of focus" under CC7.1, which means auditors are specifically looking for it even though the standard stops short of making it mandatory.

In practice, if you show up to an audit without vulnerability scan evidence, you're going to have a harder time. Not impossible, but harder.

Why Organizations Run Scans Beyond the Audit Requirement

Compliance aside, regular scanning catches problems before they become incidents. A misconfigured firewall rule, an unpatched server, a web application with a known SQL injection flaw: these are the kinds of things that show up in scans weeks or months before an attacker finds them.

For SOC 2 specifically, scan results give your auditor concrete evidence that you're monitoring your environment. That's a much easier conversation than trying to explain your monitoring approach in the abstract.

Scans also help with prioritization. When you have limited security resources (and who doesn't), knowing which vulnerabilities carry the most risk lets you spend time where it counts.

The Downsides Are Real Too

Automated scanners aren't perfect. They generate false positives, sometimes a lot of them. Your team will spend time investigating findings that turn out to be non-issues.

They also miss things. A scanner checks against a database of known vulnerabilities, so novel attack vectors or complex logic flaws won't show up. That's why pen testing still matters as a complement.

And then there's the volume problem. If you're scanning a large environment, you might get hundreds or thousands of findings. Without a good process for triaging and tracking remediation, those reports just become noise.

How Scanning Maps to the Trust Services Criteria

Principle	How Scanning Helps
Security	Finds weaknesses in your systems before attackers do. This is the most direct connection.
Availability	Catches vulnerabilities that could be exploited to take services offline.
Processing Integrity	Reduces the chance of unauthorized changes to data or processing logic.
Confidentiality	Identifies exposure points where sensitive data could leak.
Privacy	Flags vulnerabilities in systems that store or process personal information.

Practical Advice for Getting This Right

How often you scan and what you scan should be driven by your risk profile, not by a generic recommendation. At minimum, run scans quarterly and after any significant infrastructure change. Many organizations scan weekly or even continuously.

More important than scan frequency is what you do with the results. Auditors want to see that findings get triaged, assigned, and remediated within reasonable timeframes. A scan that sits in someone's inbox for six months does more harm than good during an audit.

Neither vulnerability scanning nor penetration testing is strictly required by SOC 2. But both signal to auditors (and to your customers) that you take security seriously rather than just checking boxes.
