Vulnerability Assessment Services — Know Your Weaknesses Before Attackers Do

A vulnerability assessment is a systematic scan of your network, systems, and applications to identify known security weaknesses, then rank them by severity so your team knows exactly what to fix first. It’s typically the fastest, most cost-effective way to get a baseline view of your security posture — and often the first step before deeper testing like penetration testing. PS INFOSEC combines automated scanning with manual validation, so your report reflects genuine risk, not a flood of false positives.

What Is a Vulnerability Assessment?

A vulnerability assessment systematically scans your IT environment — networks, servers, applications, and endpoints — against known vulnerability databases (like the CVE database) to identify security gaps such as missing patches, misconfigurations, weak encryption, and outdated software. Each finding is scored using CVSS (Common Vulnerability Scoring System), which rates severity from low to critical based on how easily it could be exploited and how much damage it could cause.

Unlike penetration testing, a vulnerability assessment doesn’t attempt to exploit the weaknesses it finds — it identifies and documents them. This makes it faster and less expensive than a full penetration test, while still giving you a clear, prioritized picture of where your risk actually sits. Many organizations run vulnerability assessments regularly (monthly or quarterly) and penetration tests less frequently (annually or after major changes), using the two together for continuous risk visibility.

Types of Vulnerability Assessment We Offer

Network Vulnerability Assessment

Scanning internal and external network infrastructure — servers, routers, firewalls — for unpatched software, open ports, and misconfigurations.

Application Vulnerability Assessment

Identifying vulnerabilities in web applications and APIs at the code and configuration level, without the full manual exploitation of a penetration test.

Host-Based Vulnerability Assessment

Scanning individual servers, workstations, and endpoints for missing patches, weak configurations, and outdated software versions.

Cloud Vulnerability Assessment

Reviewing cloud infrastructure (AWS, Azure, GCP) for misconfigurations and exposed resources — see our Cloud Security Assessment page for a deeper cloud-specific engagement.

Continuous / Periodic Vulnerability Management

Ongoing scanning on a monthly or quarterly cadence, so new vulnerabilities are caught as they emerge rather than only during an annual review.

Our Vulnerability Assessment Process

Why Manual Validation Matters

Pure automated scanning has a well-known problem: a meaningful share of “critical” findings in a raw scanner report turn out to be false positives once you actually investigate them — outdated version banners that don’t reflect the real patch level, or configurations that look risky in isolation but are mitigated elsewhere. Handing a client an unfiltered scanner export isn’t a vulnerability assessment; it’s a scan.

At PS INFOSEC, every finding is manually reviewed before it reaches your report. This means your team isn’t spending time chasing down issues that aren’t real, and the findings that are in the report can be trusted and prioritized with confidence.

Frequently Asked Questions

What is the difference between vulnerability assessment and penetration testing?

A vulnerability assessment identifies and lists known weaknesses using scanning and CVSS-based scoring. A penetration test goes further, actively exploiting those weaknesses to prove real-world business impact. Many organizations use VA for regular, frequent checks and penetration testing for deeper, periodic validation.

How often should we run a vulnerability assessment?

Most organizations benefit from monthly or quarterly scans, plus an assessment after any significant infrastructure or application change. High-compliance environments (BFSI, healthcare) often run them more frequently.

How long does a vulnerability assessment take?

It depends on the number of assets in scope — a small application or network segment can be assessed quickly, while a large enterprise environment takes longer. We confirm exact timelines during scoping.

What is CVSS scoring?

CVSS (Common Vulnerability Scoring System) is an industry-standard framework that rates a vulnerability's severity from 0 to 10 based on factors like how easily it can be exploited and what impact it would have — giving a consistent, comparable severity rating across different types of findings.

Can vulnerability assessment findings be false positives?

Raw automated scan output often includes false positives. That's why manual validation is a core part of our process — every finding is reviewed before it appears in your report, so you're not chasing down issues that aren't real.

Do you offer ongoing vulnerability management, or only one-time assessments?

Both. We offer one-time assessments as well as continuous/periodic vulnerability management on a monthly or quarterly cadence for organizations that want ongoing visibility rather than a single point-in-time snapshot.
