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 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 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: Google Analytics, Facebook, Twitter, Cloudflare, Google APIs

      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

Convertiser holds a solid position in the Polish affiliate marketing ecosystem, leveraging a business model focused on providing flexible affiliate tools and APIs to publishers. Its competitive advantages include a diverse widget portfolio, real-time analytics, dedicated support, and a referral program. The company targets a broad range of digital content creators, including blogs, social media profiles, and product review sites. Growth indicators include expanding campaign offerings and integration capabilities. The partnership ecosystem includes major e-commerce players and technology providers. The company maintains a consistent brand presence and transparent communication channels, enhancing its credibility and market trust.

Security posture

The website demonstrates a moderate to good security posture with mandatory HTTPS, domain status protections, and cookie consent mechanisms. However, it lacks DNSSEC, security.txt, and published security policies or incident response contacts, which are important for transparency and vulnerability management. No critical vulnerabilities or exposed sensitive data were detected. The use of Google Tag Manager introduces moderate tracking but is standard practice. Recommendations include enabling DNSSEC, implementing security headers, and publishing a security policy to improve trust and compliance.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a formal security policy and incident response contact information on the website.
  4. Add a security.txt file to facilitate responsible vulnerability disclosure.
  5. Continue monitoring third-party scripts and tracking tools to ensure privacy compliance.

Technical notes

Notes

The website is built on a modern static site generator (Hugo), ensuring fast load times and good performance. It uses Google Tag Manager for analytics and Cloudflare for DNS, indicating a reliable infrastructure. The site is mobile-optimized and SEO-friendly with proper meta tags and structured navigation. No CMS vulnerabilities are present due to static site architecture. However, the absence of DNSSEC and some security headers indicates room for technical security improvements. The site’s technical debt appears low, but ongoing updates to security practices and privacy compliance are recommended to maintain operational resilience.
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.
