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

6 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. 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"

  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 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';…

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 positions itself as a multidisciplinary firm offering comprehensive services in finance and law. Its business model revolves around providing auditing, tax, and legal consulting services to clients, supported by a strong employer branding strategy to attract talent. The presence on platforms like Kununu and social media channels indicates active engagement with its audience and a focus on transparency. The firm operates in the German market with multiple office locations. The website content and structure suggest a medium-sized enterprise with a stable market position and a focus on long-term growth and employee development.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and a cookie consent mechanism that respects user privacy and GDPR requirements. No exposed sensitive data or vulnerable libraries were detected. However, the absence of explicit security policies or incident response contacts is a gap. Security headers such as Content-Security-Policy and X-Frame-Options are not evident and could be added to enhance protection. Overall, the site is secure for typical business operations but could benefit from formalizing security documentation and response procedures.

Recommendations

  1. Implement and enforce security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a dedicated security policy and provide incident response contact information to improve transparency and trust.
  3. Regularly audit and update all plugins and third-party libraries to prevent vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Continue monitoring and optimizing website performance and mobile responsiveness.

Technical notes

Notes

The website is built on WordPress CMS, utilizing jQuery and MediaElement.js for media playback, and Borlabs Cookie for GDPR-compliant cookie management. Google Tag Manager is used for analytics and tracking. The site loads CSS and JavaScript assets efficiently with lazy loading and caching plugins. Mobile optimization is good with responsive design and adaptive layouts. SEO is supported by meta tags, Open Graph, and JSON-LD structured data. No major technical debt or outdated technologies were detected, though some improvements in accessibility and security headers are recommended.
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.
