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

Firstlead GmbH operates the website firstlead-server.de as a service platform in partnership with the affiliate network ADCELL. The site primarily serves as an informational landing page providing company contact details and links to the ADCELL affiliate network. The business model focuses on affiliate marketing services targeting advertisers and affiliates in Germany. The website content is minimal and presented in both German and English, reflecting a small-sized technology sector company with a basic online presence. Technically, the website uses Cloudflare for DNS hosting but lacks a valid SSL certificate, resulting in no HTTPS support. The site includes Google Analytics and Google Tag Manager scripts for tracking but does not implement cookie consent mechanisms or advanced SEO features. Performance is moderate with basic mobile optimization and accessibility. The meta robots tag is set to noindex, indicating the site is not intended for public search engine indexing. From a security perspective, the absence of a valid SSL certificate is a critical vulnerability, exposing users to potential data interception risks. No security headers or advanced security policies are implemented. Privacy compliance is partial, with a privacy policy and terms of service linked externally on the ADCELL domain but no cookie consent or explicit GDPR compliance indicators on the site itself. Overall, the website presents a low-risk profile due to its limited functionality and content but requires urgent improvements in SSL configuration and privacy compliance to enhance trustworthiness and security posture.

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

6 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. 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';…

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

Firstlead GmbH operates within the affiliate marketing sector, leveraging a partnership with ADCELL to provide network services. The business targets advertisers and affiliates primarily in Germany, positioning itself as a niche player in the affiliate marketing technology space. Revenue streams likely derive from affiliate commissions and advertising services. The company maintains a small-scale digital footprint with limited direct customer engagement on this site. The partnership with ADCELL is a key strategic asset, providing brand recognition and operational support. Growth indicators are not evident from the site content, and the business model relies heavily on the affiliate network ecosystem. The lack of extensive content or interactive features suggests a focus on backend service provision rather than direct consumer marketing.

Security posture

The current security posture is weak due to the lack of HTTPS and an invalid SSL certificate, which is a critical issue for any web service. No security headers or advanced configurations such as HSTS or CSP are present. The site does not expose sensitive data or forms, reducing attack surface but also limiting functionality. Privacy compliance is minimal, with no cookie consent mechanisms and limited GDPR indicators. Incident response and vulnerability disclosure policies are not found, indicating immature security governance. The use of Google Analytics introduces moderate user tracking without clear consent, which may pose compliance risks. Overall, the security maturity is low, and remediation should prioritize SSL deployment, security headers, and privacy compliance enhancements.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across the site.
  2. Implement security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security with preload and includeSubDomains.
  3. Add a cookie consent banner/mechanism to comply with GDPR and ePrivacy Directive requirements.
  4. Publish clear privacy and cookie policies directly on the site with explicit GDPR compliance statements.
  5. Establish an incident response contact channel such as security@ or abuse@ email addresses.
  6. Improve website content and navigation to enhance user experience and SEO.
  7. Regularly audit third-party scripts and tracking tools to minimize privacy risks.
  8. Consider adding structured data (JSON-LD) and Open Graph tags for better SEO and social media integration.
  9. Enhance mobile optimization and accessibility features to improve usability.
  10. Develop a vulnerability disclosure policy and publish a security.txt file to foster transparency.

Technical notes

Notes

The website is hosted behind Cloudflare DNS but lacks a valid SSL certificate, resulting in no HTTPS support. The tech stack includes Google Analytics and Google Tag Manager for user tracking. The site is a simple static HTML page with inline CSS and no CMS detected. Performance is moderate with a page load time of approximately 3.2 seconds and a page size of 264 KB. Mobile optimization is basic with responsive image scaling. SEO is limited due to the noindex meta tag and absence of meta description or Open Graph tags. Accessibility is basic with standard HTML semantics but no ARIA roles or landmarks. The technical debt is low given the site's simplicity but modernization opportunities include SSL deployment, enhanced SEO, and improved privacy controls.
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.
