Risk levelHigh

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

The website www.o2marketscan.cz represents a business intelligence and analytics product branded under the O2 name, specifically offering competitive web traffic analysis using data from the O2 network. The service targets businesses seeking detailed insights into their own and competitors' web traffic, providing graphs, reports, and market segment analysis. The site is professionally designed, mobile-optimized, and uses modern JavaScript frameworks and analytics tools such as Exponea and Google Analytics. Privacy and cookie policies are present and appear GDPR compliant, with a consent management platform integrated. However, the WHOIS data for the domain is unavailable, which reduces transparency and trustworthiness from a domain registration perspective. No explicit security or incident response policies are published, and no direct contact emails or phone numbers are provided, only contact forms. Overall, the website is credible and professional but would benefit from improved transparency and security disclosures.

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

10 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

    • 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

  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 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';…

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 business operates in the telecommunications sector, leveraging O2's network data to provide unique competitive insights into web traffic. Its business model is B2B, focusing on data analytics and market intelligence services. The company positions itself as a provider of precise, aggregated data directly from O2's infrastructure, offering clients a competitive edge. The partnership with inCUBE interactive s.r.o for website development indicates a professional approach to digital presence. The lack of WHOIS data is a concern but the strong O2 branding and privacy policy linkage to O2 domains support legitimacy. The target customers are businesses interested in market and competitor analysis, likely medium-sized enterprises or larger. The product's key services include visitor analysis, loyalty metrics, and impact evaluation of market changes.

Security posture

The website enforces HTTPS and integrates Cloudflare Turnstile captcha for bot protection, indicating a good baseline security posture. Cookie consent is managed via a CMP, and forms submit data securely via POST with JSON responses. However, no explicit security headers were detected in the provided data, and no published security or incident response policies were found. The absence of a vulnerability disclosure policy or security.txt file limits transparency for security researchers. No vulnerabilities or exposed sensitive data were observed in the content. Overall, the security posture is good but could be enhanced by publishing security policies, adding security headers, and providing incident response contacts.

Recommendations

  1. Publish explicit security policies and incident response contact information on the website.
  2. Add standard security HTTP headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Provide direct company contact emails and phone numbers for sales and security inquiries to improve trust and accessibility.
  5. Verify and update WHOIS domain registration information to improve transparency and domain legitimacy.

Technical notes

Notes

The website uses modern front-end technologies including Alpine.js for reactive UI components and Exponea for analytics and marketing automation. It integrates third-party services such as Calendly for scheduling and Cloudflare Turnstile for bot mitigation. The site is mobile-optimized with responsive images and well-structured HTML. Performance appears fast with asynchronous script loading and lazy loading of images. SEO is supported by proper meta tags and Open Graph data. No CMS was detected, suggesting a custom or static site build. Hosting provider details are not evident from the data. Overall, the technical infrastructure is modern and well-implemented, supporting a professional user experience.
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.
