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

The website corona-zahlen-heute.de is a German-language informational portal focused on providing up-to-date COVID-19 statistics worldwide and detailed data for Germany. It aggregates official data sources and presents them with visualizations and detailed regional breakdowns. The site targets the general public interested in pandemic tracking and health data. Technically, the site uses modern web technologies including JavaScript, SVG for maps, Google Fonts, and Google Adsense for monetization. Hosting is via Cloudflare, providing performance and security benefits. Security posture is strong with HTTPS enforced and Content-Security-Policy headers present, though additional headers could improve security further. Privacy compliance is moderate; a cookie consent mechanism is implemented, but no explicit privacy policy or terms of service pages were found in the provided content. No direct contact information or incident response contacts are visible. Overall, the site is professional, trustworthy, and safe for general audiences, with a moderate AI score reflecting good content and technical implementation but some gaps in privacy and contact transparency.

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

5 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  2. GDPR outside view

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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

The site operates as a niche informational service providing COVID-19 data aggregation and visualization primarily for German-speaking users. Its business model relies on advertising and affiliate marketing, as evidenced by Google Adsense and affiliate links to Amazon and eBay. The portal leverages official data sources to maintain credibility and daily updates to ensure relevance. The lack of explicit company or contact information suggests a small or individual operator rather than a large enterprise. The site’s market position is that of a specialized data aggregator in the public health domain, serving users seeking detailed pandemic statistics. Growth potential depends on continued relevance of COVID-19 data and user trust. Partnerships appear limited to affiliate programs and Google services.

Security posture

The website demonstrates a solid security foundation with HTTPS enabled and a Content-Security-Policy header enforcing upgrade of insecure requests. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The use of Cloudflare DNS and hosting adds a layer of protection and performance optimization. However, the absence of additional security headers such as X-Frame-Options and Referrer-Policy is a minor gap. No vulnerability disclosures or incident response contacts are provided, which could be improved to enhance security transparency. Overall, the site’s security posture is good but could benefit from enhanced header policies and published security practices.

Recommendations

  1. Publish a clear and comprehensive privacy policy page to improve GDPR compliance and user trust.
  2. Add terms of service to clarify user rights and site policies.
  3. Include explicit contact information for general and security-related inquiries.
  4. Implement additional security headers such as X-Frame-Options, X-Content-Type-Options, and Referrer-Policy.
  5. Establish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.

Technical notes

Notes

The website uses a modern tech stack with JavaScript-driven interactive maps (SVG), Google Fonts for typography, and Google Adsense for monetization. Hosting via Cloudflare provides DNS and CDN services enhancing performance and security. The site is mobile optimized with responsive design and includes accessibility features at a basic level. SEO is supported by proper meta tags including Open Graph and Twitter cards, and JSON-LD structured data for search engine understanding. Performance is moderate, likely influenced by external scripts and ad loading. No CMS was detected, suggesting a custom or static site architecture. Technical debt appears low, but improvements in accessibility and security headers could be made.
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.
