Risk levelMedium

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

Smoobu is a medium-sized German-based company offering an all-in-one SaaS platform for vacation rental management. Their software suite includes a Channel Manager, Property Management System, Booking Engine, Guest Communication tools, Dynamic Pricing, and Website Builder, targeting vacation rental property owners and managers. The company positions itself as a professional and trusted player in the hospitality software market, with strong industry partnerships including Airbnb, Booking.com, and Expedia. The website is well-designed, multilingual, and optimized for SEO and mobile devices, reflecting a mature digital presence. Technically, the site is built on WordPress with modern JavaScript libraries and integrates multiple analytics and marketing tools such as Google Tag Manager, Snowplow, and Reddit Pixel. The site uses HTTPS and demonstrates good security hygiene, although it lacks some advanced security headers and explicit security policies. Privacy compliance is well addressed with clear privacy and cookie policies and consent mechanisms. Security posture is solid with no visible vulnerabilities or exposed sensitive data, but the absence of WHOIS transparency and security incident response information slightly reduces trust. Overall, the website and business appear legitimate and professional, with room for improvement in security disclosures and WHOIS transparency. Strategic recommendations include enhancing security headers, publishing a formal security policy and incident response plan, and adding a vulnerability disclosure program to strengthen trust and 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

4 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 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';…

  2. 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 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

Smoobu operates in the hospitality sector, focusing on vacation rental management software. Their business model is subscription-based SaaS, offering tiered plans with features tailored to different customer needs. The company leverages partnerships with major booking platforms to enhance service integration and market reach. Their target customers are vacation rental owners and managers seeking to automate and optimize booking, communication, and pricing. The presence of a free trial and extensive educational resources indicates a customer-centric approach aimed at growth and retention. The company maintains a consistent brand and professional online presence, supported by active social media channels and customer testimonials, positioning them competitively in the vacation rental software market.

Security posture

The website employs HTTPS and integrates cookie consent management, indicating awareness of privacy and security best practices. However, no explicit security headers such as Content Security Policy or HSTS were detected, and there is no published security policy or incident response information. No vulnerability disclosure or security.txt file is present, which are common in mature security programs. The absence of WHOIS data reduces transparency. Overall, the security posture is good but could be improved by formalizing security policies, enhancing HTTP headers, and providing clear incident response contacts to increase trust and compliance with standards like GDPR and NIS2.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Publish a comprehensive security policy and incident response plan accessible from the website.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Improve WHOIS transparency or provide verified domain registration information to enhance trustworthiness.
  5. Continue monitoring and updating privacy compliance mechanisms to align with evolving regulations.

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.
