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. 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. 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 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

    • High

      Third-party services without privacy policy

      Detected services: LinkedIn, YouTube

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

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

opper operates in the media and technology sectors, targeting media companies, agencies, and independent businesses requiring audience and content management solutions. Their business model is B2B, offering software suites (subsuite, adsuite, marketingsuite), data tools (andzup), and consulting services. The company benefits from a strong market position with long-term client relationships and recognized certifications like Qualiopi. Partnerships such as job listings on welcometothejungle.com enhance recruitment efforts. The company emphasizes innovation and customer support, positioning itself as a comprehensive media technology provider.

Security posture

The website employs HTTPS with a valid SSL configuration and integrates Google reCAPTCHA to protect contact forms from abuse. Cookie consent is managed via Axeptio, indicating GDPR compliance. However, no explicit security policy or incident response information is publicly available, which could be improved to enhance transparency and readiness. Security headers are not explicitly detected in the HTML content, suggesting potential for further hardening. No vulnerabilities or exposed sensitive data were found in the analysis. Overall, the security posture is good but could benefit from documented policies and enhanced header configurations.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Provide clear incident response contact information for security issues.
  3. Implement and enforce security headers such as Content-Security-Policy and X-Frame-Options.
  4. Regularly audit third-party scripts and dependencies for vulnerabilities.
  5. Enhance transparency by publishing data retention and privacy impact details.

Technical notes

Notes

The website is built on WordPress 6.8.1 with Elementor 3.29.0, leveraging modern JavaScript and CSS techniques for responsive and accessible design. It uses Google Fonts, Google reCAPTCHA, Axeptio for cookie consent, and Piwik PRO for analytics. The site loads efficiently with lazy loading and prefetching strategies. The technical stack is modern and well-maintained, supporting good performance and user experience. Hosting provider details are not explicitly available. Opportunities exist to improve security headers and publish more detailed technical and security documentation.
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.
