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

AK RENNER is a Czech Republic based law firm specializing in energy law, environmental law, and related legal services. The firm emphasizes an interdisciplinary approach, combining legal expertise with knowledge of energy and regulatory frameworks to provide comprehensive legal consulting and representation. Their market position is that of a niche expert in the energy sector with a small but professional operation. The website is well designed, content-rich, and professionally presented, targeting business clients in the energy and public sectors. Technically, the site is built on WordPress with modern plugins and frameworks, offering good performance and mobile optimization. Security posture is solid with HTTPS and cookie consent mechanisms, though additional security headers and explicit policies could improve it. The absence of WHOIS data is a concern for domain legitimacy but the overall business credibility remains high based on website content and trust indicators. Strategic recommendations include enhancing security headers, publishing security policies, and verifying domain registration details to improve 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.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  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

The firm operates in the energy legal advisory sector, offering services such as legal representation, public relations, and energy consulting. Their business model focuses on providing specialized legal expertise with a strong emphasis on client trust, integrity, and comprehensive service. The presence of a subsidiary company focused on energy consulting indicates diversification and growth. Testimonials and memberships in professional bodies reinforce their market credibility. The target customers are businesses and organizations requiring expert legal advice in energy and environmental matters. The firm appears to maintain a high level of professionalism and client satisfaction, positioning itself as a trusted partner in its niche.

Security posture

The website employs HTTPS and a cookie consent mechanism, indicating awareness of privacy and security compliance. However, no advanced security headers were detected, and there is no visible security or incident response policy published. No vulnerabilities or exposed sensitive data were found in the analysis. The absence of a security.txt file or vulnerability disclosure policy suggests room for improvement in transparency and incident handling readiness. Overall, the security posture is good but could be enhanced by adopting additional best practices and publishing relevant policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  2. Publish a clear security policy and incident response plan accessible on the website.
  3. Add a security.txt file to facilitate vulnerability disclosure and improve transparency.
  4. Verify and publish domain WHOIS registration details to enhance trust and legitimacy.
  5. Regularly audit and update third-party plugins and scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on WordPress CMS using Elementor page builder and several modern JavaScript libraries such as GSAP, ApexCharts, and Lottie Player for animations and charts. The site uses responsive design techniques and is optimized for mobile devices. Performance is moderate with some heavy slider and animation elements but overall user experience is smooth. SEO is supported by proper meta tags and structured content. The technical stack is modern and well maintained, though hosting provider details are not disclosed. There is no evidence of outdated or vulnerable libraries in use. Opportunities exist to improve security headers and streamline some heavy front-end components for better performance.
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.
