See every exposure. Fix what matters first.

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.

System hardening is the process of reducing a system's attack surface by removing unnecessary services, closing unused ports, enforcing strong authentication and applying secure configuration settings. Hardening is usually measured against a baseline such as the CIS Benchmarks.

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.

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.

Yes. NetGuard can run entirely inside your data center, including isolated and air-gapped networks, so scan data never leaves your infrastructure. A private-cloud option is also available.
