Barrion vs Nessus
Barrion and Nessus serve different layers. Barrion focuses on web application security: TLS, headers, cookies, and web-facing misconfigurations, with passive scanning safe for production. Nessus scans infrastructure and networks for vulnerabilities, patch levels, and compliance. This comparison helps you see where each fits.
Comparison at a glance
| Aspect | Barrion | Nessus |
|---|---|---|
| Scope | Web app: URLs, headers, TLS, cookies, email config, exposure | Infrastructure: hosts, network, OS, apps, cloud assets |
| Scan type | Passive (read-only), production-safe | Active: port scan, credential checks, plugin-based CVE detection |
| Primary use case | Continuous web app monitoring, compliance evidence, step-by-step fixes | Vulnerability management, patch prioritization, infra compliance |
| Production | Designed for production, zero risk | Often run on internal/test or scheduled maintenance windows |
| Remediation | Step-by-step fixes per finding, PDF/CSV export | Findings with CVEs and remediation guidance, integration with Tenable ecosystem |
| Pricing | Free tier, paid for monitoring | Commercial (Nessus Professional, Tenable.sc), free limited (Nessus Essentials) |
Who Barrion is best for
Teams that need continuous visibility into web app security (headers, TLS, misconfigurations) without touching infrastructure. Good for dev teams, agencies, and anyone who wants production-safe web checks and audit-ready reports.
Who Nessus is best for
Teams that need infrastructure and network vulnerability management, CVE tracking, and compliance scanning across servers and cloud. Essential for traditional VM programs and asset-centric security.
Summary
Barrion and Nessus address different layers. Use Barrion for web app security and continuous monitoring of your sites and APIs. Use Nessus (or Tenable) for infrastructure and network vulnerability management. Many organizations use both: Nessus for infra, Barrion for web.
