By accessing or using HeaderGuard (headerguard.veridux.ai / headerguard.io), operated by VeriduxLabs, you agree to be bound by these Terms of Service. If you do not agree, do not use the service.
HeaderGuard is a security header scanning tool that analyzes HTTP response headers for URLs you submit. The service provides a letter grade (A through F), identifies missing or misconfigured security headers, and generates copy-paste fix snippets for popular web servers and frameworks including Next.js, Express, Nginx, Apache, and Cloudflare. Paid plans include continuous monitoring with Slack alerts when headers change.
You agree to only scan URLs for domains and services you own or have explicit authorization to test. You must not use HeaderGuard to:
HeaderGuard offers a free tier for on-demand scans and paid monitoring plans for continuous header tracking with alerts. Payments are processed through Paddle, which acts as the Merchant of Record. Paddle handles all billing, tax calculation, and compliance. Subscription terms, cancellation, and refund policies are governed by Paddle's terms. You can cancel your subscription at any time through your account settings.
HeaderGuard is provided "as is" and "as available" without warranties of any kind, either express or implied. Security header analysis and grades are automated assessments based on industry best practices and publicly available standards. They are intended as guidance to help you improve your security posture, not as a guarantee of protection. A high HeaderGuard grade does not mean your site is fully secure, and a low grade does not necessarily mean your site is vulnerable to attack. You are solely responsible for your own security decisions.
To the maximum extent permitted by law, VeriduxLabs and its operators shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of HeaderGuard, including but not limited to security incidents that occur despite following HeaderGuard recommendations, or damages resulting from reliance on scan results.
We strive to keep HeaderGuard available at all times but do not guarantee uninterrupted access. We may perform maintenance, updates, or modifications to the service at any time. For paid monitoring plans, we will make reasonable efforts to notify you of planned downtime that may affect monitoring alerts.
HeaderGuard, its design, code, and branding are the property of VeriduxLabs. Scan results generated for your URLs are yours to use. The fix snippets provided are offered under a permissive license — you may freely use them in your projects.
We reserve the right to suspend or terminate your access if you violate these terms, particularly the acceptable use provisions around unauthorized scanning. You may stop using HeaderGuard at any time and delete your account through account settings.
We may update these terms from time to time. Changes will be posted on this page with an updated revision date. Continued use of HeaderGuard after changes constitutes acceptance of the revised terms.
