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

Bouk is a SaaS hospitality management platform developed by OpenHotels, offering a comprehensive suite of modules including booking engines, property management, invoicing, and guest services. The platform targets a broad range of hospitality properties such as small hotels, hotel chains, spa resorts, vacation homes, and apartments, positioning itself as an all-in-one solution with integrations to major booking platforms like Booking.com and Airbnb. The website demonstrates a modern technical infrastructure built as a React single-page application, hosted on AWS with integrations for analytics and payment processing via Stripe. Security posture is solid with HTTPS enforcement and domain transfer protections, though improvements such as enabling DNSSEC and adding security headers are recommended. Privacy compliance is basic, with privacy and cookie policies present but lacking detailed GDPR compliance indicators. Business credibility is supported by clear product offerings and trusted platform integrations, though direct contact information is not prominently provided. Overall, Bouk presents as a professional and trustworthy platform with room for enhancement in security transparency and privacy 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

8 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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

Bouk operates in the hospitality technology sector, providing an integrated management system that simplifies operations for property owners and managers. Its competitive advantage lies in consolidating multiple hospitality functions into a single platform, reducing the need for disparate systems. The business model is subscription-based SaaS, targeting hospitality businesses of various sizes. The company leverages partnerships with major booking platforms to enhance market reach and customer acquisition. Growth indicators include a relatively recent domain registration and active integrations. The absence of detailed contact information and security policies suggests a focus on product development and customer acquisition over public-facing corporate transparency at this stage.

Security posture

The website employs HTTPS and has domain transfer protections, indicating a baseline security maturity. However, the lack of DNSSEC, security headers, and published security policies or incident response contacts points to gaps in security best practices. No vulnerabilities or exposed sensitive data were detected in the analysis. Privacy compliance is basic, with cookie consent mechanisms in place but limited GDPR-specific disclosures. The absence of a vulnerability disclosure policy or security.txt file reduces transparency for security researchers. Overall, the security posture is moderate but could benefit from enhanced security controls and transparency to build greater trust.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement and publish comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a detailed security policy and incident response contact information to improve transparency and readiness.
  4. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Enhance privacy policy details to explicitly address GDPR compliance and data retention practices.

Technical notes

Notes

The website is built as a modern React single-page application, leveraging cloud hosting on AWS and integrating third-party services such as Stripe for payments and FullStory for analytics. The use of Google Tag Manager indicates a structured approach to marketing and analytics. Performance is moderate with asynchronous loading of scripts and optimized font loading. Mobile optimization is good, with responsive design elements evident. However, accessibility features appear basic and could be improved. SEO optimization is present but minimal, with standard meta tags but no advanced structured data or Open Graph tags detected. Overall, the technical infrastructure is solid but could benefit from enhancements in accessibility and SEO.
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.
