Where Intruder Wins
We believe in honest comparisons. Here's where Intruder has a genuine advantage today.
Internal Network Scanning
Intruder offers agent-based internal scanning on Pro+ plans. NoxScan currently focuses on external attack surface only. If internal scanning is a hard requirement, Intruder has the edge here.
Cloud Auto-Sync
Intruder connects directly to AWS, Azure, and GCP to automatically discover cloud assets. NoxScan's auto-discovery works through scanning, not cloud API integration. For heavy cloud environments, Intruder's approach is more convenient.
Nessus Engine (Pro Plan)
Intruder's Pro plan ($499/mo) includes the Tenable Nessus scanning engine - widely considered the gold standard for vulnerability detection depth. This is a significant capability, though it comes at a high price point.
Brand & Ecosystem
Intruder has broader integrations (Jira, Teams, GitHub), recognized market presence, and a larger content library. If brand maturity and a wider ecosystem matter more than scanner depth, Intruder has the edge there.
Where NoxScan Wins
The capabilities that set NoxScan apart from Intruder - and every other scanner in its class.
Full 65535-Port Scanning on Every Plan
Intruder scans approximately 1000 "common" ports across all plans - even the $499/mo Pro tier. NoxScan scans every single TCP port, every time, on every plan including the $10/mo Starter. That's 64,535 more ports per asset, every scan. Services running on non-standard ports (dev servers on 3000, admin panels on 8443, databases on 27017) are invisible to Intruder but fully visible to NoxScan.
AI False-Positive Filtering
NoxScan uses AI to verify every finding before it reaches your dashboard. The AI analyzes scan results in context - checking exploitability, cross-referencing configurations, and filtering noise. Intruder has no AI verification, so your team spends more time sorting raw engine output. NoxScan keeps the queue focused on verified, actionable findings - no chasing ghosts.
70-93% Lower Cost
NoxScan starts at $10/mo for full-feature scanning. Intruder starts at $149/mo - and you need to pay $499/mo for the Pro plan to get the Nessus engine. At 10 assets, you save $250/mo. At 50 assets, you save $350+/mo. That's $3,000-4,200 per year back in your budget - with more port coverage.
Core Scanner Stays Intact
Every NoxScan paid plan includes full 65535-port scanning, AI verification, SOC 2 evidence mapping, and compliance-ready PDF reports. NoxScan still unlocks workflow extras like API access, webhooks, seats, and white-label reporting on higher plans, but the scanner itself does not get stronger only after you buy up. Intruder gates its best engine (Nessus) behind the Pro plan and limits Nuclei scanning to Cloud+.
PDF Reports Stay Attached to the Run
NoxScan turns completed scans into PDF reports without rebuilding the story in a separate reporting workflow. The evidence stays tied to the run and the finding that produced it. Intruder has broader platform reporting, but the handoff path is less opinionated around the scan itself.
SOC 2 Evidence Database with Per-Control Mapping
NoxScan doesn't just generate a compliance report - it maps every scan result to specific SOC 2 controls (CC7.1, CC3.2, CC4.1, CC7.2) and ISO 27001 controls (A.8.8) in a dedicated Evidence Database. Intruder offers compliance report generation, but without the granular per-control mapping and evidence tracking.
Auto-Discovery via Scanning
When NoxScan's port scan finds an HTTP service on any port - standard or non-standard - it automatically creates a domain asset and queues it for web vulnerability scanning. A service running on port 8443 doesn't just show as "open port" - it gets full Nuclei web scanning. Intruder's auto-discovery relies on cloud API connectors, which don't detect unauthorized or shadow services.
Frequently Asked Questions
NoxScan scans all 65535 TCP ports on every asset, every scan, on every plan - including the $10/mo Starter. Intruder scans approximately 1000 common ports across all plans, even the $499/mo Pro tier. This means NoxScan covers 64,535 more ports per asset, catching services on non-standard ports that Intruder would miss entirely.
Yes, significantly. NoxScan starts at $10/mo for 1 asset with full features. Intruder starts at $149/mo. At 10 assets, NoxScan costs $49/mo vs Intruder's $299/mo (84% savings). At 50 assets, NoxScan is $149/mo vs Intruder's $499+/mo (70%+ savings). And NoxScan includes full port scanning and AI verification at every tier - Intruder gates Nessus behind the $499/mo Pro plan.
Yes - and Intruder does not. NoxScan uses AI to verify every finding before it reaches your dashboard, automatically filtering false positives and classifying severity with contextual analysis. Intruder relies on raw output from OpenVAS and Nessus without AI verification.
Absolutely. NoxScan has a dedicated Evidence Database that maps scan results to specific SOC 2 Trust Service Criteria: CC7.1 (detection and monitoring), CC3.2 (risk assessment), CC4.1 (risk response), and CC7.2 (system monitoring). ISO 27001 control A.8.8 (access control) is also mapped. Every compliance-ready PDF report documents these mappings so your auditor can review the evidence. Intruder offers compliance reports but without per-control mapping or evidence tracking.
Yes, and we think it's important to be transparent about this. Intruder offers internal network scanning (via an agent on Pro+ plans), cloud auto-sync with AWS/Azure/GCP for automatic asset discovery, access to the Tenable Nessus scanning engine on Pro, Emerging Threat / Rapid Response scans, and a broader integration ecosystem including Jira and Microsoft Teams. Intruder also has a more established brand and market presence. If any of these are hard requirements, you should evaluate both products.
Yes. Add your assets to NoxScan and start scanning immediately. There's no complex migration process - NoxScan will run a full 65535-port scan and auto-discover web services. You can run both tools in parallel during a transition period. Start with a free trial to see how NoxScan's results compare to your current Intruder scans.
NoxScan currently focuses on external attack surface monitoring. If internal scanning is a requirement, you have two options: use NoxScan for external scanning (at a fraction of Intruder's cost) and a separate tool for internal, or wait for NoxScan's internal scanning capability which is on the roadmap. Many teams find that comprehensive external scanning at $10-149/mo plus a dedicated internal tool costs less than Intruder's Pro plan ($499/mo) for both.
