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

SFÉRA, a.s. is a Slovak-based company specializing in proprietary IT platforms and software solutions for the energy, rail transport, and industrial sectors. Their flagship platforms, XMtrade® and XMatik®, support energy trading, distribution, rail vehicle monitoring, and asset management, positioning them as a key regional player in these industries. The website reflects a professional and business-focused approach with clear service offerings and a target audience of energy companies, transport operators, and industrial enterprises. Technically, the website employs modern web technologies including AngularJS, Google Tag Manager, and reCAPTCHA, with a CMS based on Umbraco. The site is mobile-optimized and provides a good user experience with clear navigation and relevant content. Security-wise, the site uses HTTPS, implements reCAPTCHA on forms, and includes GDPR-compliant privacy and cookie policies. However, it lacks explicit security policies and incident response contacts, and could improve by adding security headers and terms of service. Overall, the domain registration details align well with the business claims, supporting legitimacy and trustworthiness.

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

5 findings rated critical or high. Fix these first.

  1. 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 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';…

  2. GDPR outside view

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

    • 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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 company operates a B2B business model focused on delivering specialized IT solutions to energy and transportation sectors. Their proprietary platforms provide competitive advantages in market-specific software, including energy trading systems and rail vehicle dispatching. The presence of consulting and advisory services indicates diversified revenue streams. The company maintains partnerships with industry events and workshops, enhancing its ecosystem and market presence. The website content and structure suggest a medium-sized enterprise with a stable market position in Slovakia and potentially neighboring regions. The clear display of legal and billing information, along with professional contact channels, supports business credibility and customer trust.

Security posture

SFÉRA, a.s. demonstrates a moderate to good security posture. The use of HTTPS and Google reCAPTCHA protects data in transit and mitigates automated abuse of contact forms. GDPR compliance is evident through privacy and cookie policies and explicit user consent on forms. However, the absence of published security policies, incident response contacts, and security.txt files indicates room for improvement in transparency and preparedness. No critical vulnerabilities or exposed sensitive data were detected in the website content. Security headers are not explicitly observed, which could enhance protection against common web attacks. Overall, the security maturity is adequate for the business size but could be strengthened to meet higher compliance and security standards.

Recommendations

  1. Publish a formal security policy and incident response plan accessible on the website.
  2. Add terms of service to clarify user and business obligations.
  3. Implement and configure security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options.
  4. Enhance accessibility features to improve compliance and user experience.
  5. Maintain and regularly update privacy and cookie policies to reflect evolving regulations.

Technical notes

Notes

The website is built on a modern technology stack including AngularJS for frontend interactivity, Umbraco CMS for content management, and integrates Google Tag Manager and reCAPTCHA for analytics and security. The site loads asynchronously loaded scripts and uses lazy loading for images, contributing to moderate performance. Mobile optimization is good, with responsive design elements and accessible navigation. SEO optimization is basic, with meta tags and Open Graph data present but limited keyword and description content. The site could benefit from improved accessibility compliance and enhanced performance tuning. Hosting details are not explicitly identified but the presence of Cloudflare scripts suggests CDN usage. Overall, the technical infrastructure supports the business needs effectively with opportunities for modernization and security hardening.
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.
