  • Adept ($49/month, billed monthly; $149/month for 5-20+ users at launch price): Includes all Apprentice features plus unlimited Shadow SOC and Investigation across all scans, scheduled re-triage, findings tracking over time, 5 cloud connections, 30-day scan history, custom reports & exports, scan comparison & trends, full compliance gap analysis, evidence upload & tracking.
  • Master ($199/month for 5-25+ users): Builds on Adept by adding the Remediation Agent for approving and applying fixes with 30-day rollback, and Monitoring for drift detection.
  • Cyber Sensei Strike Team ($499/month): The most comprehensive plan, offering a coordinated pipeline of four AI agents (Shadow SOC, Investigation, Remediation, Monitoring) for 'full autopilot' security operations.

Pros

  • +Comprehensive passive audit covering DNS, TLS, headers, CSP, privacy notice, exposures, and CVE mapping.
  • +Integration of multiple specialized AI agents (Shadow SOC, Investigation, Remediation) for automated security tasks.
  • +Offers a free 'Apprentice' tier, making basic AI-powered security accessible.
  • +Provides both a security score and an AI-authorship likelihood index.
  • +Includes features for compliance gap analysis, evidence tracking, and cloud cost optimization.

Cons

  • API is not available, which may limit integration into existing security workflows for some users.
  • Direct independent user reviews and testimonials are not readily available in public search results.

Similar Tools

Vulnexa vs Competitors

Vulnexa positions itself as an AI-first cloud security platform, differentiating through its integrated suite of AI agents for end-to-end automation from triage to remediation. It competes with traditional cloud security posture management (CSPM) tools and vulnerability management solutions.

1
Mozilla Observatory

It provides a comprehensive score based on a wide range of web security best practices, including HTTP headers, TLS, CSP, and Subresource Integrity.

Observatory covers many of Vulnexa's audit points like TLS, headers, and CSP, and provides a similar overall security score. However, it does not explicitly audit DNS configurations, perform CVE mapping, or offer an AI-authorship likelihood index like Vulnexa.

2
Hardenize

It offers continuous monitoring and reporting across DNS, TLS, HTTP, and email security configurations, providing insights into potential misconfigurations.

Hardenize provides a broader scope of passive audits, including DNS, TLS, and HTTP headers, similar to Vulnexa. While its free tier offers valuable insights, it may not include the detailed 'exposures' or 'CVE mapping' that Vulnexa mentions, nor the AI-authorship index.

3
Qualys SSL Labs

It performs an in-depth analysis of a website's SSL/TLS server configuration, identifying vulnerabilities and providing a detailed rating.

SSL Labs is highly specialized in TLS configuration analysis, offering a much deeper dive into this specific area than Vulnexa. However, it does not cover other aspects like DNS, HTTP headers, CSP, or CVE mapping that Vulnexa audits.

4
Security Headers

It specifically analyzes a website's HTTP response headers for security best practices and provides a clear grade.

Security Headers focuses exclusively on HTTP security headers, providing a quick and clear assessment for this specific area. This is a narrower scope compared to Vulnexa, which audits a broader range of web security configurations beyond just headers.
