Why teams switch from Nessus
Scanning detects. PentestForge validates, analyzes, chains, and reports.
AI pentest agent, not just a scanner
Deep Pentest AI independently rediscovers, validates, and chains findings. It runs its own recon, exploits vulnerabilities with safe PoCs, builds attack paths, and eliminates false positives. Nessus is a scanner — it detects, but doesn't validate or exploit.
AI analysis in every report
Every PentestForge report includes an LLM-generated executive analysis with critical issues, attack vectors, business risks, and urgency-tiered remediation. Nessus provides scan results and basic PDF exports, not AI-analyzed reports.
Vulnerability chat advisor
Ask questions about your findings in real-time AI chat threads. Discuss remediation, request re-analysis, and bridge report artifacts into chat. Nessus has no interactive AI chat capability.
Compliance-ready reports, not raw scan output
Board-ready reports with SOC 2, ISO 27001, and NIS2 compliance mapping, attack chain documentation, and evidence quality ratings. Nessus provides scan exports without compliance alignment or attack chain analysis.
Attack chains, not vulnerability lists
PentestForge links individual findings into realistic multi-step attack scenarios — SSRF-to-cloud-credentials, SQLi-to-auth-bypass, LFI-to-RCE. Nessus lists vulnerabilities but doesn't show how they chain together.
Transparent per-scan pricing
Pay per scan, not per asset or IP. Nessus Professional starts at $3,590/year for 16 IPs. Tenable.io and Tenable.sc require enterprise quotes. PentestForge pricing is transparent and scales with your needs.
