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 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

    • 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

  3. 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

Mollie operates in the finance sector as a payment service provider, targeting businesses seeking efficient payment solutions. Its business model centers on facilitating payments online and in-person with honest pricing and a variety of payment methods. The company appears to have a strong market position in Europe, supported by a professional digital presence. The website's marketing tools and tracking mechanisms indicate an active approach to customer acquisition and campaign tracking. However, the absence of visible contact information and policy documents on the analyzed page may impact user trust and compliance perception. The lack of WHOIS data reduces transparency but does not negate the company's apparent legitimacy based on website content.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enabled and secure cookie attributes set. However, the absence of key security headers such as Content-Security-Policy and HSTS reduces the overall security robustness. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The site uses Google Tag Manager for analytics and tracking, which is standard but requires proper configuration to avoid privacy issues. Incident response and security policy information are not present, indicating potential gaps in transparency and readiness. Overall, the security posture is adequate but could be improved with additional headers and documented policies.

Recommendations

  1. Implement comprehensive privacy and cookie policies accessible from the website footer or dedicated pages to improve GDPR compliance and user trust.
  2. Add essential security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  3. Publish clear contact information including support and security incident contacts to improve transparency and incident response readiness.
  4. Verify and update WHOIS domain registration details to ensure transparency and reduce suspicion related to domain legitimacy.
  5. Conduct regular security audits and vulnerability scans to maintain a strong security posture and address emerging threats.

Key observations

  1. Website content is fully accessible and not blocked by WAF or security challenges.
  2. No explicit contact information or policies (privacy, cookie, terms) found in the provided HTML snippet.
  3. Website uses modern web technologies and structured data for SEO.
  4. Tracking and marketing scripts are present but limited to Google Tag Manager and session/local storage.
  5. WHOIS data is missing or unavailable, which reduces confidence in domain registration transparency.
Technical notes

Notes

The website is built using Framer CMS and integrates Google Tag Manager for analytics and marketing tracking. It uses modern web fonts and structured data (JSON-LD) for SEO optimization. Performance appears moderate with good mobile optimization and basic accessibility features. The site lacks some advanced technical SEO and security configurations such as security headers and detailed privacy mechanisms. Hosting provider details are not evident from the provided content. Overall, the technical implementation is solid but has room for improvement in security and privacy compliance.
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.
