Risk levelHigh

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

The website triangl-web.cz represents a small Czech web design and development company offering services including website creation, e-commerce solutions, CMS integration, SEO optimization, and custom internet applications. The business appears to be established since 2007 and targets local businesses and individuals seeking professional web services. The site content is primarily in Czech and provides a clear overview of services but lacks detailed contact information and compliance documentation. Technically, the website uses basic HTML, CSS, and JavaScript without modern frameworks or CMS platforms detected. The site performance and mobile optimization are basic, and no advanced accessibility features are evident. Google Analytics is used for visitor tracking, but no privacy or cookie policies are present, indicating potential compliance gaps. From a security perspective, the site lacks HTTPS enforcement and security headers, which significantly lowers its security posture. The partner login form is present but no visible security measures are implemented. The absence of WHOIS data reduces domain trustworthiness, although the website content itself appears legitimate and professional. Overall, the site scores moderately on content and business credibility but poorly on security and privacy compliance. Strategic improvements in HTTPS implementation, privacy policies, and contact transparency are recommended to enhance trust and compliance.

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

11 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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"

    • 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 · found on this site
  • 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

Triangl web operates as a small technology service provider specializing in web design, e-commerce, CMS, and custom internet applications. Its market positioning is local and focused on small to medium businesses in the Czech Republic. The company leverages a service-based business model with revenue streams from website development, online shop creation, and application programming. The absence of detailed contact information and certifications limits its competitive advantage. The partnership ecosystem is not clearly defined, and no subsidiaries or parent companies are identified. Growth indicators are not visible from the website content.

Security posture

The website demonstrates a low security maturity level with critical gaps such as missing HTTPS, lack of security headers, and absence of privacy and cookie policies. No incident response or security contact information is provided. The partner login form lacks visible security controls. These deficiencies expose the business to risks including data interception, privacy violations, and potential unauthorized access. Compliance with GDPR and other data protection regulations is not evident. The security culture appears minimal, and no certifications or frameworks are referenced.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate to secure all website traffic.
  2. Publish comprehensive privacy and cookie policies to comply with GDPR and inform users about data handling.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  4. Provide clear and verified contact information including company emails and phone numbers to improve business credibility and user trust.
  5. Establish an incident response process and publish security contact channels to demonstrate security readiness.

Technical notes

Notes

The website is built using basic web technologies (HTML, CSS, JavaScript) without modern frameworks or CMS platforms. The site lacks mobile optimization and accessibility features, which may affect user experience on diverse devices. Performance is moderate but could be improved with modern best practices. The use of Google Analytics indicates some level of visitor tracking but without visible privacy compliance. The absence of HTTPS and security headers represents significant technical debt and security risk. Hosting provider and infrastructure details are not disclosed, limiting further technical assessment.
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.
