With over 30 years of experience and a client base exceeding 1500, it offers integrated solutions to optimize content management, audience monetization, subscription handling, and commercial prospecting. The company is part of the TBS group and holds the Qualiopi certification, underscoring its commitment to quality training services. The website reflects a mature digital presence with professional design, clear navigation, and comprehensive service descriptions targeting media companies and related sectors. Technically, the site is built on WordPress with modern plugins such as Elementor and Yoast SEO, ensuring good SEO and mobile responsiveness. It employs Google reCAPTCHA v3 for form security and Axeptio for cookie consent management, demonstrating adherence to privacy regulations. Analytics are handled via Piwik PRO, indicating a preference for privacy-conscious tracking. From a security perspective, the site uses HTTPS with strong SSL configuration and implements best practices like secure forms and privacy opt-in.

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

6 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

      Third-party services without privacy policy

      Detected services: LinkedIn, YouTube, Google APIs

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

  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

opper holds a solid position in the media technology sector, leveraging decades of experience and a broad client base. Its business model focuses on B2B SaaS and consulting services, targeting media companies, agencies, and independents. The company’s integrated software suites (subsuite, adsuite, marketingsuite) and data solutions (andzup) address key pain points in audience management and commercial prospecting. Testimonials and client logos indicate strong customer satisfaction and retention. The partnership with TBS group and presence on job platforms like Welcome to the Jungle suggest healthy growth and recruitment. The company’s focus on innovation and quality certifications like Qualiopi enhance its competitive advantage. The website’s multilingual support (English, French, Italian) indicates an international orientation.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, use of Google reCAPTCHA v3 on forms, and cookie consent managed by Axeptio, supporting GDPR compliance. No exposed sensitive data or vulnerable libraries were detected. However, the absence of a published security policy, incident response contacts, and vulnerability disclosure mechanisms represents gaps in transparency and readiness. Security headers beyond HTTPS are not explicitly confirmed, suggesting room for improvement. Overall, the security measures are adequate for the business type but could be enhanced by formalizing policies and communication channels for security incidents.

Recommendations

  1. Publish a comprehensive security policy on the website to inform users and stakeholders.
  2. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  5. Regularly audit third-party libraries and plugins to ensure no vulnerabilities are introduced.

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.
