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 targets media companies, agencies, and commercial prospectors with a B2B model focused on software suites (subsuite, adsuite, marketingsuite), data solutions (andzup), and consulting services. The company leverages its longevity and client trust to maintain competitive advantage. The presence of client logos and testimonials indicates strong customer satisfaction and market penetration. The partnership with TBS group and job listings on Welcometothejungle.com suggest a growing and structured organization. The business model emphasizes subscription and sales optimization, audience engagement, and data-driven prospecting, positioning Opper as a key player in media technology solutions.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, use of Google reCAPTCHA on forms, and cookie consent management via Axeptio, indicating GDPR awareness. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a published security policy, incident response information, or vulnerability disclosure mechanisms represents a compliance gap. The site could improve by explicitly implementing and documenting security headers and providing clear channels for security incident reporting. Overall, the security posture is solid but could benefit from enhanced transparency and formalized policies.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and compliance.
  2. Add incident response contact information and consider a vulnerability disclosure policy or security.txt file.
  3. Implement and explicitly document security headers such as X-Frame-Options and X-Content-Type-Options.
  4. Enhance transparency around data retention policies and analytics data handling.
  5. Maintain regular security audits and update privacy and cookie policies as regulations evolve.

Notes

The website is built on a modern WordPress CMS with Elementor for page building and Yoast SEO for optimization, ensuring good SEO and accessibility. It uses Piwik PRO for analytics, providing privacy-focused tracking, and integrates Google reCAPTCHA for bot protection. The site loads quickly and is mobile-optimized with responsive design and lazy loading techniques. The use of Axeptio for cookie consent demonstrates compliance with privacy regulations. No major technical debts or outdated libraries were detected. Hosting provider details are not explicit, but the infrastructure appears robust and professionally managed.
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.
