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

2 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.

    • 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. 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

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

Reservanto targets a broad range of customers from individual entrepreneurs to large corporations and government entities, positioning itself as a versatile booking platform. Its business model is SaaS-based, generating revenue through subscription plans and possibly transaction fees. The presence of a referral program indicates active marketing and growth strategies. The company leverages partnerships with payment and hosting providers and maintains a professional online presence with social media engagement. The website content and branding are consistent and support a high level of trust and professionalism.

Security posture

The website demonstrates a solid security posture with HTTPS enforced, use of Google reCAPTCHA to protect forms, and no visible exposure of sensitive data. Security headers are partially confirmed but could be enhanced by explicitly implementing HSTS, X-Frame-Options, and Referrer-Policy headers. The absence of a published security policy or vulnerability disclosure program limits transparency. No critical vulnerabilities or suspicious activities were detected in the content or scripts. Overall, the security maturity is good but can be improved with formal policies and additional headers.

Recommendations

  1. Publish a dedicated security policy page including incident response contacts.
  2. Implement and verify security headers such as HSTS, X-Frame-Options, and Referrer-Policy.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Regularly audit third-party scripts and dependencies for vulnerabilities.
  5. Enhance transparency by providing data retention policies and detailed privacy compliance information.

Technical notes

Notes

The website uses a custom CMS with a modern JavaScript tech stack including jQuery, Moment.js, GSAP, and integrates Google Tag Manager and Smartlook for analytics and user behavior tracking. Performance is moderate with good mobile optimization and accessibility features. The site loads external fonts and scripts asynchronously to improve user experience. Hosting and domain registration are stable and consistent with the business profile. Opportunities exist to modernize frameworks and improve performance metrics further, but overall the technical infrastructure supports the business needs effectively.
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.
