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

7 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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  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 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';…

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

Sunlab's business model revolves around providing comprehensive digital marketing services with a focus on performance and data-driven strategies. Their cross-functional teams and proprietary technologies like BiddingLab and Feed-Engine enable them to deliver customized solutions that enhance client ROI. The agency serves a diverse client base, including global players and medium-sized enterprises, emphasizing partnership and transparency. Their marketing technology stack and strategic consulting services position them as a key player in the German and broader European digital marketing landscape. The company's strong client portfolio and high recommendation rates indicate robust growth and market trust.

Security posture

The website demonstrates a high level of security maturity with HTTPS enabled and multiple security headers implemented, reducing risks of common web vulnerabilities. No exposed sensitive data or vulnerable libraries were detected in the analysis. However, the lack of a dedicated security policy or incident response page and absence of a vulnerability disclosure mechanism suggest areas for improvement in transparency and readiness. Privacy compliance is generally good, supported by a comprehensive privacy policy, but the missing cookie consent mechanism could expose the company to regulatory scrutiny. Overall, the security posture is strong but could benefit from enhanced user-facing security documentation and consent management.

Recommendations

  1. Implement a visible and compliant cookie consent banner to enhance privacy compliance and user trust.
  2. Publish a dedicated security policy and incident response page to improve transparency and preparedness.
  3. Consider adding a vulnerability disclosure or security.txt file to encourage responsible reporting.
  4. Regularly audit third-party libraries and dependencies to prevent potential vulnerabilities.
  5. Enhance accessibility features to ensure compliance with standards and improve user experience.

The use of Partytown indicates an effort to optimize third-party script loading for performance. The CMS backend is powered by Strapi, facilitating content management and localization. Performance is optimized with responsive design, efficient asset loading, and good SEO practices including comprehensive meta tags and structured data. The site is mobile-optimized and accessible, though some improvements in accessibility could be made. Overall, the technical infrastructure is robust, scalable, and aligned with current best practices in web development.
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.
