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

3 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 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 operates in the technology and media sectors, focusing on B2B digital advertising solutions. Its business model revolves around providing technology that enhances ad engagement through streaming optimization. The market positioning is that of a niche innovator with a focus on quality creatives and measurable outcomes. The absence of direct contact emails or phone numbers suggests a controlled communication channel via web forms. The use of multiple analytics and marketing tools indicates an active approach to data-driven marketing and retargeting. No parent or subsidiary companies are identified, and the company appears to be small-sized with consistent branding and content quality.

Security posture

The website demonstrates a solid security foundation with enforced HTTPS, modern security headers, and bot mitigation via Google reCAPTCHA v3. Cookie consent is managed through Cookiebot, supporting GDPR compliance. However, the lack of a dedicated security policy or incident response contact reduces transparency in security governance. No vulnerabilities or exposed sensitive data were detected in the analysis. The security score is high but could be improved by publishing explicit security and incident response information and implementing a vulnerability disclosure policy.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Consider adding direct company contact emails or phone numbers to improve business credibility and user trust.

Technical notes

Notes

The website leverages a modern React-based Gatsby framework, ensuring good performance and SEO optimization. It uses Google Tag Manager, Google Analytics, LinkedIn Insight Tag, and Cookiebot for analytics and consent management. The site is mobile optimized with responsive design and basic accessibility features. Hosting details are not explicitly identified, but the use of CDN and preconnect hints suggests a well-architected infrastructure. Performance is moderate with room for improvement in accessibility and possibly further optimization of loading times. No CMS is detected, indicating a custom or static site generation approach.
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.
