0–100, higher is better. How it is calculated

Aircastles s.r.o. is a small digital creative agency based in the Czech Republic specializing in branding, web design, video production, photography, and online marketing services. The company presents itself as a professional and experienced team focused on creating engaging digital experiences and functional brands. Their website reflects a modern and clean design built on WordPress with Oxygen Builder, indicating a moderate level of digital maturity and technical competence. The site is mobile-optimized and SEO-friendly, though some content is still under development. Security posture is good with HTTPS enforced and no visible vulnerabilities, but the absence of security headers and cookie consent mechanisms suggests room for improvement.

Overall, the website is safe, business-focused, and suitable for general audiences.

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

9 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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"

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

Aircastles operates in the media sector as a creative digital studio targeting businesses seeking branding and digital marketing services. Their business model centers on providing creative content and digital strategy solutions. The presence of client logos and a privacy policy indicates a degree of trust and professionalism. The company appears to be small-sized with a localized market focus in the Czech Republic. The website's use of modern CMS and SEO tools suggests an intent to maintain a competitive digital presence. However, the absence of detailed references and incomplete service descriptions may indicate ongoing development or a lean operational model. No partnerships or subsidiaries were identified from the website content.

Security posture

The website demonstrates a good security baseline with HTTPS enabled and no exposed sensitive data in the HTML. Use of nonce tokens in AJAX requests indicates awareness of security best practices. However, the lack of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options is a notable gap that could expose the site to certain web-based attacks. There is no visible incident response or security policy documentation, which could be a concern for compliance and readiness. Cookie consent mechanisms are absent, which may affect GDPR compliance. No vulnerabilities or malicious indicators were detected in the site content or scripts. Overall, the security posture is solid but could be enhanced with additional headers and compliance features.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  2. Add a cookie consent banner or mechanism to comply fully with GDPR and improve user privacy transparency.
  3. Publish terms of service and security policy pages to enhance legal compliance and user trust.
  4. Consider adding incident response contact information and a vulnerability disclosure policy to demonstrate security maturity.
  5. Regularly review and update WHOIS information to improve domain transparency and trustworthiness.

Technical notes

Notes

The website is built on WordPress 6.8.3 using the Oxygen Builder framework, leveraging jQuery and AOS for animations. The tech stack is modern and supports responsive design and SEO optimization. Performance is moderate with lazy loading of images implemented. Accessibility is basic but present. The site uses standard web fonts and icon sets such as FontAwesome. No major technical debt or outdated libraries were detected. Hosting provider details are not disclosed. The site could benefit from enhanced accessibility features and improved security headers. Overall, the technical implementation supports a professional and functional digital presence.
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.
