SIXNET internet technologies s.r.o. is a well-established Slovak technology service provider specializing in web design, e-commerce solutions, graphic design, SEO optimization, and webhosting services. Operating since 2003, the company targets businesses and individuals seeking professional digital presence and marketing support, primarily in the Slovak market. Their website reflects a mature digital infrastructure with modern frontend technologies and a strong focus on user experience and mobile optimization. Technically, the website employs popular libraries such as Bootstrap, jQuery, and Fancybox, ensuring responsive design and interactive features. The presence of Google Analytics and Google Consent Mode indicates a commitment to data-driven marketing while respecting privacy regulations. The site is secured with HTTPS and includes a comprehensive cookie consent mechanism, demonstrating GDPR compliance. From a security perspective, the site shows good practices such as encrypted connections and no visible sensitive data exposure. However, it lacks explicit security policies or incident response contacts, which could be improved.

Strategic enhancements in security transparency and incident response readiness would further strengthen their posture.

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

8 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"

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

SIXNET holds a solid position as a local technology service provider in Košice, Slovakia, with over two decades of experience. Their business model focuses on delivering comprehensive digital services including web development, e-commerce platforms, graphic design, SEO, and hosting. The company leverages digital marketing tools such as Google Ads and social media campaigns to reach their target audience of businesses and entrepreneurs. Their portfolio of client references and active social media presence supports their market credibility. The absence of parent or subsidiary companies suggests an independent operation with a focused regional market. Growth indicators include ongoing projects and a regularly updated blog, reflecting engagement and expertise sharing.

Security posture

The website demonstrates a good security baseline with HTTPS enforced and a robust cookie consent framework aligned with GDPR. The use of Google Consent Mode further enhances privacy compliance. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of HTTP security headers and a published security policy or incident response contact reduces the overall security maturity. There is no evidence of a vulnerability disclosure program or security.txt file. The company should consider implementing these to improve transparency and readiness. Overall, the security posture is solid but could benefit from formalized policies and enhanced header configurations.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection to harden the website against common attacks.
  2. Publish a clear security policy and provide an incident response contact email (e.g., security@sixnet.sk) to facilitate vulnerability reporting and improve trust.
  3. Create and host a security.txt file at the root domain to formalize vulnerability disclosure procedures.
  4. Regularly audit third-party libraries and dependencies to ensure no known vulnerabilities are present.
  5. Enhance transparency by detailing data retention policies and cookie usage in the privacy documentation.

Technical notes

Notes

The website uses a modern and widely supported frontend technology stack including Bootstrap 5.3.2, jQuery 3.7.1, Fancybox, and Slick Carousel, ensuring responsive and interactive user experience. The site is mobile-optimized with adaptive images and viewport settings. Google Tag Manager and Google Analytics are integrated for performance and marketing analytics. The CMS appears custom or proprietary, as no common CMS signatures were detected. Performance is moderate, likely influenced by video backgrounds and multiple external scripts. Accessibility features are present but could be further enhanced with ARIA roles and semantic HTML improvements. SEO is supported by meta tags, Open Graph data, and canonical URLs. Overall, the technical implementation is solid with room for optimization in performance and accessibility.
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.
