Medium risk. 9 critical or high findings in Email security, Security headers and 2 other checks.
12 Days of Web is a niche educational website created by Stephanie Eckles that offers a year-end series of tutorials and articles focused on fundamental web technologies such as HTML, CSS, and JavaScript. The site targets web developers and enthusiasts seeking to deepen their understanding of modern web development techniques. The business model centers around content publishing with an email subscription service for daily updates during December, supported by open-source sponsorship and donations. The website maintains a consistent brand and provides quality content with clear navigation and good user experience. Technically, the site is built using the Eleventy static site generator, leveraging modern web standards including HTML5, CSS3, and JavaScript. It uses Plausible Analytics, a privacy-focused analytics platform, and includes accessibility and SEO best practices. The site performs well with fast loading times and mobile optimization. However, no explicit hosting provider or advanced platform integrations are identified. From a security perspective, the site uses HTTPS as implied by external script sources, but lacks explicit security headers such as Content-Security-Policy or HSTS. Forms use POST methods with basic anti-bot hidden fields, but no published security policies or incident response contacts are available. Privacy and cookie policies are absent, representing compliance gaps. No vulnerabilities or exposed sensitive data were detected. Overall, the website is trustworthy and professional with a strong focus on educational content. The domain registration data aligns well with the website's author and content, supporting legitimacy. Strategic recommendations include publishing privacy and cookie policies, implementing security headers, and adding vulnerability disclosure information to enhance compliance and security posture.
Scanned
NIS2 Art. 21(2)
This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.
GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.
9 findings rated critical or high. Fix these first.
SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.
Domain is vulnerable to email spoofing
What to do: Implement SPF, DKIM, and DMARC immediately
Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.
Prevents clickjacking attacks
What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"
Controls resources the browser is allowed to load
What to do: Implement a Content-Security-Policy appropriate for your application
These are the privacy signals visitors and data protection authorities look for under GDPR.
GDPR requires a clear and accessible privacy policy

GDPR requires clear information about cookie usage
What to do: Add a dedicated cookie policy explaining cookie usage and purposes
GDPR requires explicit consent for non-essential cookies
What to do: Implement a cookie consent banner that appears on first visit

Each check with its score, findings and the evidence it collected.
The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted
Findings that cap the score at 49
Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.
Partial scans
When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
