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

Sonntag & Partner Partnerschaftsgesellschaft mbB operates as a specialized IT consulting and software development firm based in Augsburg, Germany. The company focuses on delivering tailored solutions in digital transformation, IT compliance, process management, and project management. Their market position is that of a boutique consultancy with a strong emphasis on compliance and innovative technologies such as AI and low-code development. The website reflects a professional and consistent brand image targeting business clients seeking expert IT services. Technically, the website is built on WordPress with modern plugins and libraries, including jQuery and Borlabs Cookie for consent management. The site is mobile-optimized and demonstrates good SEO practices, although some accessibility features could be enhanced. Performance is moderate, with no critical errors or broken elements detected. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms compliant with GDPR. However, explicit security headers are not detected in the HTML content, and no dedicated security policy or incident response contacts are provided. No vulnerabilities or exposed sensitive data were found, indicating a solid baseline security posture. Overall, Sonntag IT Solutions presents a trustworthy and professional online presence with strong compliance and business credibility. Strategic improvements in security headers and incident response transparency would further enhance their security posture and client 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

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

  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 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';…

  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

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 company targets mid-sized to small enterprises and organizations requiring IT compliance, digital transformation, and software development services. Their business model centers on consulting and project-based engagements, leveraging partnerships with technology providers such as Bizagi, JobRouter, and Lucanet. The firm maintains memberships in regional and cybersecurity alliances, enhancing its credibility and network. Recent news and events indicate active business development and thought leadership in the IT compliance and digitalization space. The partnership ecosystem and service diversity position Sonntag IT Solutions competitively within the German IT consulting market.

Security posture

Sonntag IT Solutions maintains a good security baseline with HTTPS enforced and GDPR-compliant cookie consent mechanisms. The absence of explicit security headers such as Content-Security-Policy or X-Frame-Options suggests room for improvement. No incident response or vulnerability disclosure information is publicly available, which could be a gap in transparency. The website does not expose sensitive data or use vulnerable libraries based on the HTML content analysis. Overall, the security posture is adequate for a consulting firm but would benefit from enhanced header policies and published security practices.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  3. Regularly audit and update third-party scripts and plugins to mitigate potential vulnerabilities.
  4. Enhance website accessibility features to comply with WCAG standards.
  5. Maintain and communicate clear data retention and privacy policies aligned with GDPR.

Technical notes

Notes

The website is built on WordPress 6.8.3, utilizing common JavaScript libraries such as jQuery and MediaElement.js for video playback. The Borlabs Cookie plugin manages cookie consent, indicating attention to privacy compliance. The site uses slick carousel for content sliders and loads resources asynchronously for performance. While the site is mobile responsive and SEO optimized, some CSS and JavaScript could be further optimized for faster load times. Hosting provider details are not explicitly identified, but domain name servers suggest professional hosting. No critical technical debt or outdated technologies were detected.
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.
