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

Protel Systems s.r.o. operates a professional hotel management software platform targeting Czech and Slovak hotel businesses. Their website showcases a comprehensive suite of hotel management tools including PMS, payment solutions, online check-in/out, digital reception, and more. The company holds certifications such as Best Western and features testimonials from reputable clients, indicating a strong market position in the hospitality technology sector. Technically, the website is built on the Solidpixels CMS platform, uses modern web technologies including Google Tag Manager and Cookiebot for analytics and privacy compliance, and is well optimized for mobile devices. Security posture is good with HTTPS enforced and cookie consent mechanisms in place, though the absence of a published security policy and incident response contact reduces transparency. The lack of WHOIS data is a notable concern for domain legitimacy, but the professional presentation and business information mitigate some risk. Overall, the site is trustworthy, business-focused, and compliant with GDPR requirements.

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

    • 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

  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

      • 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';…

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

Protel Systems targets mid-sized hotels and hotel chains in the Czech Republic and Slovakia, offering integrated software solutions to streamline hotel operations. Their business model is B2B SaaS with additional consulting and support services. The company leverages partnerships and certifications to enhance credibility and market reach. Revenue streams likely include software licensing, subscription fees, and value-added services such as automated mailing and conference management. The website content and client testimonials suggest a stable customer base and ongoing growth potential. Strategic focus on digital transformation in hospitality positions Protel well against competitors.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and cookie consent implemented, aligning with GDPR standards. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in transparency and preparedness. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. The use of reputable third-party services for analytics and consent management further supports security hygiene. Enhancing security headers and publishing formal policies would strengthen trust and compliance.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and compliance.
  2. Provide clear incident response contact information, including security@ or abuse@ email addresses.
  3. Implement and publicize a vulnerability disclosure program or security.txt file.
  4. Enhance website accessibility to meet higher standards for inclusivity.
  5. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security.

Technical notes

Notes

The website is built on the Solidpixels CMS platform, utilizing modern JavaScript libraries such as Swiper for sliders and Google Tag Manager for analytics. It loads Google Fonts for typography and uses Cookiebot for cookie consent management. The site is mobile optimized with responsive design and features multiple interactive forms for lead generation and contact. Performance appears moderate with asynchronous loading of scripts. No hosting provider information was found. The technical stack supports a professional user experience but could benefit from enhanced accessibility and security header implementation.
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.
