Vulnz Agent.
Super-lightweight Vulnz plugin for WordPress.
Built for Performance
Vulnz Agent (vulnz-agent) is the lightweight companion plugin for Vulnz. It acts as the secure bridge between your WordPress site and your Vulnz dashboard.
- Zero Bloat: No dashboard widgets, no upsell banners, and no persistent background processes.
- Read-Only: It takes a snapshot of your installed plugins and themes to check for vulnerabilities, but it never modifies your site data.
- Open Source: Fully transparent and GPLv2 licensed. You can audit every line of code.
