What's included
What you get with BoringSec
One focused Security Audit shows what was verified, what still needs authorization, and the fixes you can ship.
Fast and self-serve
Paste a URL and see the maximum available lightweight findings, evidence, counts, and coverage in about a minute. No sales call, account, agent, or onboarding is required.
17 pre-verification URL modules plus 6 verified-owner heavy scanners (3 external engines)
The pre-verification modules report first. Injection, XSS, Ports, Nuclei, ZAP, and Medusa start only after a signed-in owner verifies the domain. Applicable, authorization-required, and unavailable states remain explicit.
One evidence-backed A++ to F grade
The overall score and grade stay N/A until every required category, including all six verified-owner heavy scanners, settles with fully verified coverage. Findings and severity remain visible before then.
AI-ready fixes
Plain-language remediation with copy-paste prompts for Cursor, Claude Code, Lovable, Bolt, v0, and Windsurf.
Evidence before conclusions
Confirmed, partial, unavailable, and authorization-required checks stay distinct, so an untested surface is never presented as clean.
Priced for builders
Transparent, low pricing with reports in 10 languages, optional continuous monitoring, and API / CI-CD / Slack hooks.
Decision guide
Which one fits your team?
Tenable (Nessus) and BoringSec solve different problems. Here is the honest split.
Tenable (Nessus) is the better fit when
- You need deep credentialed scanning of internal networks, servers, and OS/device-level CVEs, not just an external website scan
- You need formal compliance audits against benchmarks like CIS, PCI DSS, or HIPAA across many assets
- You want an industry-standard scanner with very broad CVE coverage and an enterprise platform behind it
BoringSec is the better fit when
- You want a self-serve answer without a demo, onboarding, or sales call
- You are an indie developer, founder, or small team shipping an AI-built app (Cursor, Lovable, v0, Bolt, Windsurf) and want affordable, self-serve pricing
- You want broad coverage in one pass plus plain-language, AI-ready fixes, not an enterprise console to operate
- You want one focused website Security Audit with clear evidence states, concrete remediation, and reports available in 10 languages
