0–100, higher is better. How it is calculated

CSS Tip is a small, niche educational website focused on providing daily CSS tips and tricks to web developers. The site targets front-end developers seeking to improve their CSS skills and stay updated with modern web features. The business model relies primarily on content publishing supported by advertising revenue from networks such as BuySellAds and Carbon Ads. The site demonstrates good content quality, consistent branding, and clear navigation, making it a useful resource within its niche. Technically, the website is built using the Eleventy static site generator and hosted on OVH infrastructure. It integrates common web technologies including JavaScript, Google Analytics, and advertising scripts. While the site is mobile optimized and accessible, it suffers from slow load times and lacks a valid SSL/TLS certificate, which impacts security and user trust. From a security perspective, the site has significant weaknesses including no HTTPS, absence of security headers, no DNSSEC, and no privacy or cookie policies. These gaps expose the site and its users to potential risks and reduce compliance with privacy regulations such as GDPR. No contact or incident response information is provided, limiting transparency and trust. Overall, CSS Tip is a functional and content-rich site with moderate professionalism but critical security and privacy shortcomings. Addressing SSL configuration, implementing privacy policies, and improving security headers would substantially enhance its security posture and user trust.

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.

Priority findings

7 findings rated critical or high. Fix these first.

  1. Security headers

    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.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

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

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

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.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

CSS Tip occupies a niche market in the web development education sector, focusing on CSS tips and tricks. Its competitive advantage lies in daily updated content and a clear focus on CSS, appealing to front-end developers. The business model is content-driven with monetization through advertising. The site leverages partnerships with advertising networks and promotes related CSS tools and resources. Growth indicators include regular content updates and integration with social media platforms. However, the lack of direct contact information and privacy policies may limit broader commercial opportunities and trust with enterprise clients.

Security posture

The website's security maturity is low due to the absence of HTTPS and lack of security headers. No advanced security frameworks or incident response mechanisms are evident. The site does not provide GDPR compliance indicators or data protection officer contacts. Vulnerabilities include missing SSL certificate, no HSTS, no DNSSEC, and no cookie consent mechanisms despite tracking scripts. These issues pose risks to user data confidentiality and site integrity. The lack of contact information for security incidents further reduces readiness. Immediate remediation of SSL and privacy compliance is recommended.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS and protect user data.
  2. Implement a comprehensive privacy policy and cookie consent mechanism to comply with GDPR and enhance transparency.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve security posture.
  4. Provide clear contact information including security incident response channels to build trust and enable reporting.
  5. Optimize website performance to reduce load times and improve user experience, especially on mobile devices.
Technical notes

Notes

The website is built on a modern static site generator (Eleventy) and hosted on OVH infrastructure. It uses standard web technologies including JavaScript and integrates third-party services such as Google Analytics and advertising networks. The site is mobile optimized and accessible with good SEO metadata. However, the lack of a valid SSL certificate and slow load times indicate technical debt and potential risks. There is no evidence of a CMS in use, though Statamic is advertised in a sidebar ad. The technical stack is simple but requires improvements in security and performance to support business continuity and user trust.
Standards and sources

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.
