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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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

The company positions itself as a client-focused media agency offering excellent service, flexible processes, and data-driven campaign management. It leverages partnerships with major media groups to provide competitive buying conditions. The business model centers on media buying and strategic consulting, serving regional and international clients. The presence of multiple client logos and detailed company registration data enhances credibility. The agency operates in the media sector within the Czech Republic and maintains a small company size. The website content and structure support clear communication of services and business values, aiding customer acquisition and retention.

Security posture

The website employs HTTPS and standard WordPress security practices but lacks visible security headers such as CSP or HSTS. No security or incident response policies are published, and no dedicated security contact channels are provided. The use of common plugins necessitates regular updates to mitigate vulnerabilities. No exposed sensitive data or obvious vulnerabilities were detected in the HTML content. The cookie consent banner indicates some privacy awareness, but GDPR compliance details are minimal. Overall, the security posture is moderate with opportunities for enhancement in policy transparency and technical controls.

Recommendations

  1. Implement comprehensive security headers (CSP, HSTS, X-Frame-Options) to enhance protection.
  2. Publish explicit security and incident response policies on the website.
  3. Add a security.txt file to facilitate vulnerability reporting and improve transparency.
  4. Regularly audit and update WordPress plugins and themes to reduce vulnerability risks.
  5. Enhance privacy compliance disclosures, including detailed GDPR statements and data retention policies.

Notes

The website is built on a modern WordPress CMS platform with WooCommerce integration, using popular plugins like WPBakery Page Builder and Slider Revolution for content management and presentation. Google Analytics is integrated for traffic analysis. The site is mobile responsive with good design quality and navigation clarity. Performance is moderate, with potential improvements in loading speed and accessibility features. Hosting provider details are not explicitly identified. The technical stack is standard for media agencies and supports effective content delivery and user engagement.
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.
