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

AD Group is a Czech-based investment and construction group with a diversified portfolio of subsidiaries specializing in architectural design, construction realization, and real estate management including hospitality projects. The company has a well-established market presence with a history dating back to the mid-1990s. Their website reflects a professional and consistent brand image, targeting clients seeking comprehensive construction and development services in the Czech Republic. Technically, the website is built on WordPress with modern libraries such as jQuery and Owl Carousel, and includes GDPR-compliant cookie consent and Google reCAPTCHA for form security. Security posture is good with HTTPS enforced and no visible vulnerabilities, though additional security headers could enhance protection. The absence of WHOIS data reduces domain trust slightly, but overall business credibility is supported by clear contact information, subsidiary listings, and social media presence. Strategic recommendations include improving security headers, publishing a security policy, and maintaining up-to-date software to mitigate risks.

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. 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

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 operates in the real estate and construction sectors with a medium-sized business model focused on end-to-end project delivery from planning to property management. Their diversified subsidiaries cover architectural services, construction, and hospitality, indicating a broad service offering. The website's clear presentation of subsidiaries and projects suggests a mature partnership ecosystem. The presence of a charity foundation linked in the footer indicates community engagement. The business targets regional clients in the Czech Republic, leveraging a professional online presence to support growth and market positioning. No direct revenue streams or financial data are disclosed, but the comprehensive service portfolio and multiple brands imply a stable business operation.

Security posture

The website demonstrates a moderate to strong security posture with HTTPS enabled and Google reCAPTCHA v3 protecting forms against spam. Cookie consent mechanisms comply with GDPR requirements, reflecting good privacy practices. However, the site lacks advanced security headers such as Content-Security-Policy and Strict-Transport-Security, which could further harden defenses. No security.txt or incident response contacts are published, which limits transparency in vulnerability reporting and incident management. No exposed sensitive data or vulnerable libraries were detected. Overall, the security maturity is appropriate for a medium-sized business but could benefit from formalized security policies and enhanced header configurations.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security to improve defense in depth.
  2. Publish a formal security policy and incident response contact information to enhance transparency and trust.
  3. Regularly update WordPress core and plugins to mitigate known vulnerabilities.
  4. Maintain and monitor GDPR compliance with periodic reviews of cookie consent and privacy policies.
  5. Consider obtaining and displaying relevant security certifications to boost customer confidence.

Technical notes

Notes

The website is built on WordPress CMS using common plugins such as Contact Form 7 and Complianz GDPR Cookie Consent. It uses jQuery and Owl Carousel for UI components and Google reCAPTCHA v3 for spam protection. The site loads asynchronously and includes SEO-friendly meta tags and responsive design elements. Performance is moderate with room for optimization. Accessibility is basic but functional. Hosting provider details are not disclosed. The technical stack is modern and suitable for the business scale, though improvements in security headers and performance tuning could be beneficial.
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.
