What Is a Vulnerability Scanner Tool?
A vulnerability scanner tool is a software application designed to detect security weaknesses in your network, devices, or applications. These tools compare your systems against databases of known vulnerabilities (like CVEs) and alert you about potential risks.
They can:
- Identify outdated software and unpatched systems
- Scan for misconfigurations
- Highlight security holes in websites or apps
- Recommend steps to fix problems
By using a CVE scanner, you stay ahead of hackers who exploit known flaws.
Why Small Businesses Need Vulnerability Scanning
Many small businesses believe they’re too small to be targeted—but that’s a myth. Hackers often see smaller companies as low-hanging fruit because they tend to invest less in cybersecurity.
Using tools like OpenVAS, Nessus, or OWASP ZAP can help small businesses:
- Maintain compliance
- Build customer trust
- Avoid costly breaches
