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

Ulrike Lahrs Steuerberatungskanzlei is a small, local tax consultancy firm based in Twistringen, Germany, specializing in tax advisory, accounting, payroll, and tax declaration services. The website presents a professional and clear business description targeting individuals and businesses seeking tax-related services in the region. The technical infrastructure is based on the IONOS MyWebsite platform, utilizing Apache server and common JavaScript libraries such as jQuery and Cookiebot for cookie consent management. However, the website lacks HTTPS support, which significantly undermines its security posture. Security headers are partially implemented, but the Content Security Policy is in report-only mode and permits unsafe script execution, increasing risk. Privacy compliance is addressed with a GDPR-compliant privacy and cookie policy, but no terms of service or explicit security policies are found. Overall, the website is functional and professional but requires urgent security improvements to protect user data and enhance 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

8 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 business operates in the tax consultancy sector, serving a local German market with a focus on personalized and trustworthy tax advisory services. Its business model revolves around professional consulting and accounting services, targeting individuals and small businesses. The website's content and contact information reinforce its local market position. The use of IONOS hosting and website builder indicates a cost-effective digital presence. There is no evidence of partnerships or subsidiaries. The firm maintains a clear contact channel via phone and email, supporting client communication. Growth indicators or advanced digital marketing tools are not evident, suggesting a traditional business approach.

Security posture

The security maturity level of the website is low due to the absence of HTTPS and a valid SSL certificate, exposing users to potential data interception risks. While some security headers like X-Content-Type-Options and X-XSS-Protection are present, the lack of HSTS and weak Content Security Policy reduce effectiveness. No incident response or security policy information is provided, and no vulnerability disclosure or security.txt files are found. The use of Cookiebot indicates awareness of privacy regulations, but overall security practices require significant enhancement to meet modern standards and compliance requirements such as GDPR and NIS2.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire website.
  2. Implement a strict Content Security Policy disallowing unsafe-inline and unsafe-eval scripts.
  3. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  4. Add comprehensive security headers including Referrer-Policy, X-Frame-Options, and Permissions-Policy.
  5. Publish a clear security policy and incident response contact information to improve transparency and trust.

Notes

The website is hosted on an Apache server via IONOS and built using the IONOS MyWebsite CMS platform. It uses common JavaScript libraries such as jQuery and Cookiebot for cookie consent management. The site lacks modern TLS protocols and does not support HTTPS, which is a critical technical deficiency. Performance metrics are not available, but the use of multiple external resources and lack of optimization suggests moderate to slow loading times. The site is basic in mobile optimization and accessibility features. SEO is adequately addressed with meta tags and Open Graph data. Technical debt is evident in the outdated security configuration and lack of modern web standards compliance.
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.
