Risk levelHigh

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

TESCO.cz is a Czech-based technology business specializing in servers and workstations, primarily offering Intel platform servers, server components, custom configurations, and maintenance services. The website presents a straightforward informational portal targeting businesses requiring reliable IT infrastructure hardware. The domain has a long history dating back to 1997, supporting the company's established market presence. Technically, the website uses jQuery and Google Analytics but lacks modern CMS or advanced frameworks. The site is basic in design and functionality, with limited mobile optimization and accessibility features. Security posture is moderate but lacks visible HTTPS confirmation and security headers, and no privacy or cookie policies are present, indicating compliance gaps. Contact information is clearly provided, but no forms or social media links are available. Overall, the site is functional but would benefit from enhanced security, privacy compliance, and technical modernization.

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

    • 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

  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

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

TESCO.cz operates in the technology sector, focusing on B2B sales and services of servers and workstations. The company leverages its long-standing domain registration since 1997 to position itself as a reliable provider of quality Intel-based server hardware and related services. The business model centers on hardware sales, custom configurations, and maintenance consultation. The target audience includes businesses and organizations requiring robust IT infrastructure. The website content is basic but consistent with the business focus. There is no evidence of partnerships or subsidiaries from the website content. The company appears to maintain a moderate market position with potential for growth through improved digital presence and compliance.

Security posture

The website demonstrates a basic security posture with no visible forms or inputs that could expose sensitive data. However, the absence of HTTPS confirmation and security headers such as Content-Security-Policy or X-Frame-Options reduces the overall security level. No vulnerability disclosure or incident response information is provided, which limits transparency and readiness for security incidents. The use of Google Analytics without a cookie consent mechanism raises privacy compliance concerns under GDPR. Overall, the security maturity is low to moderate, with significant room for improvement in compliance and technical security controls.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate and ensure all site content is served securely.
  2. Add and prominently display privacy and cookie policies with a user consent mechanism to comply with GDPR.
  3. Deploy security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  4. Establish and publish an incident response contact channel such as security@ or abuse@ email addresses.
  5. Improve mobile responsiveness and accessibility to enhance user experience and SEO.

Technical notes

Notes

The website uses a simple technology stack including jQuery and Google Analytics for tracking. The HTML is basic and lacks modern frameworks or CMS platforms. Performance is moderate with asynchronous loading of analytics scripts. The site lacks advanced SEO meta tags and accessibility features. Hosting appears to be managed via REG-INTERNET-CZ with name servers at forpsi.net and forpsi.it, indicating a Czech hosting provider. There is no evidence of technical debt but modernization opportunities exist, especially in security and compliance implementations.
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.
