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 operates in the media and technology sectors, targeting media companies, agencies, and business developers. Their business model is B2B, providing software suites (subsuite, adsuite, marketingsuite), data solutions (andzup), and consulting services. The company benefits from a strong reputation, evidenced by long-term client relationships and industry certifications like Qualiopi. Their partnership ecosystem includes data providers and recruitment platforms. The company’s growth is supported by continuous R&D and adaptability to market trends. The website content and structure indicate a focus on customer retention, revenue optimization, and digital transformation for media clients.

Security posture

The website employs HTTPS with a valid SSL configuration and integrates Google reCAPTCHA to protect forms from abuse. Cookie consent is managed via Axeptio, indicating GDPR awareness. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents an area for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. There is no public security policy or incident response contact information, which limits transparency and readiness perception. Overall, the security posture is good but could be strengthened by publishing security policies and implementing additional HTTP headers.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy page outlining security practices, data protection measures, and incident response procedures to improve transparency and trust.
  3. Add a security.txt file at the root domain to facilitate responsible vulnerability disclosure and improve security communication.
  4. Regularly audit third-party scripts and plugins to ensure no vulnerable libraries are in use and maintain up-to-date software versions.
  5. Enhance accessibility features and conduct periodic security training to foster a strong security culture within the organization.

Technical notes

Notes

The website is built on WordPress CMS using Elementor and Yoast SEO plugins, leveraging modern web standards and JavaScript frameworks. It integrates Google Fonts, Google reCAPTCHA, and Piwik PRO analytics for tracking and performance insights. The site demonstrates good mobile optimization and SEO practices with structured data (JSON-LD) and Open Graph metadata. Performance is moderate, with lazy loading and prefetching techniques employed. Technical risks are minimal, but the lack of explicit security headers and limited hosting information suggest opportunities for infrastructure hardening and transparency improvements.
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.
