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

Steuerschroeder.de is a comprehensive German tax advisory website operated by Dipl.-Kfm. Michael Schröder, a tax consultant based in Berlin. The site offers extensive tax-related content, including detailed explanations, tax calculators, downloadable forms, and online consultation services targeting private individuals, freelancers, and small to medium enterprises in Germany. The business positions itself as a knowledgeable and experienced tax advisory service with over 30 years of expertise. Technically, the website is built on a custom PHP platform using Bootstrap 4 and jQuery, hosted likely by Strato, and integrates Google Tag Manager, Google Analytics, and Google Adsense for marketing and analytics. However, the site lacks a valid SSL certificate, resulting in no HTTPS, which is a critical security flaw. Additionally, no explicit privacy or cookie policies are found despite the use of tracking and advertising technologies, indicating compliance gaps. The WHOIS data confirms the domain's legitimacy and consistency with the business claims, though domain protection measures are absent. Overall, the site provides rich, professional content but requires urgent security and privacy improvements to enhance trust and compliance.

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

9 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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  2. 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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"

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 website serves as a digital platform for tax advisory services, combining free educational content with paid consulting and online tax declaration services. Its extensive content library and tools position it as a leading resource in the German tax advisory market, especially for individuals and SMEs. The business model leverages online presence to attract clients and provide value-added services such as newsletters and downloadable resources. The integration of affiliate marketing (Amazon) and Google advertising suggests diversified revenue streams. The target audience includes private taxpayers, freelancers, and small businesses seeking tax optimization and compliance assistance. The site’s longevity and detailed content indicate a mature operation with a strong market presence in Berlin and Germany.

Security posture

The security posture of the website is currently weak due to the absence of a valid SSL certificate, resulting in no HTTPS encryption. This exposes users to potential data interception risks, especially when submitting forms or interacting with the chatbot. The server uses Apache 2.4.63 and has no DNSSEC or CAA records configured, which are modern DNS security best practices. No HSTS or OCSP stapling is enabled, and session resumption mechanisms are absent, indicating missed opportunities for performance and security enhancements. While no known vulnerabilities like Heartbleed or POODLE are detected, the lack of HTTPS and security headers significantly lowers the security score. Furthermore, the absence of privacy and cookie policies despite tracking scripts raises compliance and privacy concerns. Incident response and security policy information are not publicly available, limiting transparency.

Recommendations

  1. Immediately obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Implement and display comprehensive privacy and cookie policies to comply with GDPR and inform users about data collection.
  3. Enable security headers such as HSTS with includeSubDomains and preload to enforce HTTPS and improve security.
  4. Configure DNSSEC and CAA records to enhance DNS security and control certificate issuance.
  5. Establish and publish a security policy and incident response contact information to improve transparency and trust.

Technical notes

Notes

The website is built on a custom PHP-based platform using Bootstrap 4 and jQuery 3.5.1, hosted on an Apache 2.4.63 Unix server, likely provided by Strato based on DNS records. It uses Google Tag Manager and Google Analytics for tracking and Google Adsense for monetization. The site employs lazy loading for images and responsive design techniques for mobile optimization. However, performance metrics are missing or zero, indicating no available data or poor measurement. The lack of HTTPS due to an invalid SSL certificate is a critical technical deficiency. The site has a rich content structure with extensive internal linking and a large sitemap, supporting good SEO. Accessibility features are basic, and no CMS is detected, suggesting manual or custom content management. Overall, the technical infrastructure is functional but requires modernization and security upgrades.
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.
