45/100

Risk levelHigh

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

BlučinaNet s.r.o. is a small Czech telecommunications company established in 2002, specializing in internet connectivity and technical infrastructure network statements primarily in the Židlochovice region. The website functions mainly as an informational and redirect portal guiding users to their new site and providing contact details for infrastructure inquiries. The technical infrastructure of the website is minimal, lacking modern CMS, SEO optimization, and mobile responsiveness. Security posture is weak due to absence of HTTPS confirmation, security headers, and privacy policies. No forms or email contacts are provided, limiting user engagement and support channels. Overall, the site reflects a basic digital presence consistent with a small regional service provider.

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. 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

  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
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  3. GDPR outside view

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

    • 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

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

BlučinaNet operates in the telecommunications sector with a niche focus on technical infrastructure services and internet connectivity. The company targets local customers requiring network statements and telecommunication services in the Czech Republic. The business model is service-oriented with limited digital marketing or e-commerce capabilities. The domain age and registration data support a stable, long-term presence. Partnerships with related domains such as blucinanet.eu indicate ongoing business continuity. The lack of certifications or trust badges suggests a modest market position without extensive formal compliance or industry recognition.

Security posture

The website exhibits a low security maturity level with no detected HTTPS enforcement, absence of security headers, and no visible privacy or cookie policies. There is no evidence of vulnerability disclosure mechanisms or incident response contacts. The lack of secure forms and minimal technical sophistication increases risk exposure. While no explicit vulnerabilities were detected, the site would benefit from implementing basic web security best practices to protect user data and improve trustworthiness.

Recommendations

  1. Implement HTTPS with a valid SSL certificate to secure all communications.
  2. Add comprehensive privacy and cookie policies to comply with GDPR and enhance transparency.
  3. Introduce security headers such as Content-Security-Policy and Strict-Transport-Security.
  4. Improve mobile responsiveness and accessibility to enhance user experience.
  5. Establish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website is a simple HTML page with no detected CMS or advanced frameworks. External links point to partner and service portals relevant to telecommunications infrastructure. There is no evidence of analytics, tracking, or advertising technologies. Performance is likely moderate given the minimal content but mobile optimization and accessibility are poor. The site lacks SEO meta tags and structured data, limiting search engine visibility. Hosting and platform details are not explicitly available, but DNS uses ns.web4u.cz and ns2.web4u.cz name servers. Overall, the technical implementation is basic and could be modernized to improve performance and security.
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.
