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

The website arbeitgeberversicherung.de represents the employer insurance services provided by Knappschaft-Bahn-See, a major German government-related insurance entity. It offers comprehensive insurance coverage for employers regarding employee sickness and maternity benefits through Umlageverfahren U1 and U2. The site targets employers in both commercial and private sectors, including those with Minijobbers and employees insured under the Knappschaft system. With over two million customers and a history dating back to 1969, it holds a strong market position in Germany's social insurance landscape. Technically, the website is built on the Government Site Builder CMS, leveraging modern JavaScript libraries, Matomo analytics, and Usercentrics for cookie consent management. The site is well-optimized for mobile and accessibility, with good SEO practices and a moderate performance profile. It uses HTTPS and encrypted form submissions, ensuring secure data handling. From a security perspective, the site demonstrates good practices such as HTTPS enforcement and consent management but lacks explicit published security policies or incident response contacts. No vulnerabilities or suspicious content were detected. Privacy compliance is strong, with clear privacy and cookie policies and GDPR adherence. Overall, the website is professional, trustworthy, and well-aligned with its government insurance service mission. Strategic improvements could include publishing dedicated security and incident response information and enhancing security headers to further strengthen its 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

4 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

    • 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

  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.

    • 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

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

Knappschaft-Bahn-See operates as a key government insurance provider specializing in employer insurance for sickness and maternity benefits. Its business model focuses on providing Umlageverfahren U1 and U2 services, facilitating quick reimbursements and administrative ease for employers. The organization benefits from a large customer base and strong partnerships with entities like the Minijob-Zentrale and ITSG. The website supports digital transformation with online forms, calculators, and an app, indicating a mature digital presence. The target market includes small to medium employers and private households, with a clear emphasis on compliance and service quality. The partnership ecosystem and transparent communication enhance its competitive advantage in the German social insurance sector.

Security posture

The website maintains a solid security posture with HTTPS encryption, secure form handling, and consent management for cookies. It uses Matomo for analytics, which can be self-hosted and privacy-friendly. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms represents a compliance gap. Security headers are not explicitly detected, which could be improved to mitigate common web threats. No vulnerable or outdated libraries were found. Overall, the site is secure but could benefit from enhanced transparency and formal security documentation to meet best practices and regulatory expectations.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information, including security@ or abuse@ email addresses.
  3. Implement and enforce security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security.
  4. Create and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Regularly review and update third-party scripts and libraries to avoid potential vulnerabilities.

It uses modern JavaScript libraries, including MediaElement.js for video playback, Matomo for analytics, and Usercentrics for GDPR-compliant cookie consent. The site is mobile-optimized and accessible, with good SEO metadata including Open Graph and Twitter Cards.

The technical stack is modern and well-maintained, supporting the business goals effectively.
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.
