What is vulnerability scanning?

Vulnerability scanning is the automated process of discovering and assessing security weaknesses in IT assets. A vulnerability scanner probes servers, workstations, network devices, databases and web applications, compares what it finds against a library of known vulnerabilities, and produces a prioritized report.

NetGuard combines network vulnerability scanning, web application scanning and configuration auditing in one vulnerability management platform, so your team sees the full picture of its exposure instead of disconnected reports.

What NetGuard's vulnerability scanner finds

Missing patches & CVEs

Operating systems, applications, network firmware and databases checked against a daily-updated vulnerability library.

Web vulnerabilities

SQL injection, XSS, broken authentication, insecure headers and the rest of the OWASP Top 10.

Weak configurations

Default credentials, insecure protocols, weak ciphers and expired or self-signed certificates.

Exposed services

Open ports, remote-access services and forgotten hosts reachable from the internet.

How vulnerability scanning works with NetGuard

  1. 1

    Define targets

    Add IP ranges, domains and web applications, or let discovery find them for you.

  2. 2

    Scan safely

    Run authenticated or unauthenticated scans on a schedule or continuously, with safe checks and scan windows.

  3. 3

    Prioritize by risk

    Every finding is scored with severity, exploit intelligence and asset criticality.

  4. 4

    Fix and verify

    Send findings to owners with remediation steps, then rescan automatically to confirm the fix.

FAQ

Frequently asked questions

What is a vulnerability scanner?

A vulnerability scanner is software that automatically checks servers, network devices, endpoints and web applications for known security weaknesses — such as missing patches (CVEs), insecure configurations, default passwords and exposed services — and reports them with a severity rating and remediation advice.

What is the difference between vulnerability scanning and penetration testing?

Vulnerability scanning is automated, broad and continuous: it finds known weaknesses across your whole environment. Penetration testing is a manual, time-boxed exercise where experts try to exploit weaknesses. The two complement each other — continuous scanning keeps your risk low between penetration tests.

What is exposure management?

Exposure management goes beyond listing vulnerabilities. It continuously discovers all assets, assesses vulnerabilities and misconfigurations, prioritizes them by exploitability and business impact, and tracks remediation until risk is verified as reduced.

Will scanning affect my production systems?

NetGuard uses safe checks by default, with bandwidth limits, concurrency controls and scan windows, so you can assess production environments without disrupting them.
