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

5 findings rated critical or high. Fix these first.

  1. 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"

    • 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';…

  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

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

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 niche legal services sector focusing on ESG and sustainability, a growing market segment driven by regulatory changes and investor demand. Its business model revolves around specialized legal advisory and transaction support, targeting medium to large enterprises and public entities in Germany. The firm leverages its expertise as a competitive advantage, supported by a strong digital presence and professional content. Partnerships or subsidiaries are not evident, but the firm maintains active social media channels to engage with clients and stakeholders. Growth potential is linked to increasing ESG regulatory complexity and demand for sustainable governance.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and no exposed sensitive data. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No vulnerability disclosure or incident response information is provided, indicating a gap in transparency and preparedness. Privacy compliance is partial due to missing privacy and cookie policies. The use of Matomo analytics suggests some privacy awareness. Overall, the security posture is adequate for a professional services website but could be improved with formal policies and enhanced headers.

Recommendations

  1. Publish comprehensive privacy and cookie policies with GDPR-compliant consent mechanisms.
  2. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a security policy or vulnerability disclosure page and consider a security.txt file.
  4. Enhance accessibility features to improve inclusivity and compliance.
  5. Regularly audit third-party scripts and update libraries to mitigate vulnerabilities.

Technical notes

Notes

The website uses WordPress CMS with a custom theme and includes jQuery 3.1.1 and Swiper.js for UI components. SEO is enhanced via Yoast SEO plugin with structured JSON-LD data for organization and webpage schema. Analytics are handled by Matomo, a privacy-focused alternative to Google Analytics. The site loads asynchronously for scripts improving performance, though overall speed is moderate. Mobile optimization is good with responsive design. Hosting is through a reputable registrar, InterNetX GmbH. Technical debt appears low, but updating jQuery to a more recent version could improve security and performance. No critical technical risks 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.
