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 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 Policy found

      GDPR requires clear information about cookie usage

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

    • 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

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

Sleap.io operates in the hospitality sector with a focus on blockchain and cryptocurrency integration. Its business model centers on providing a decentralized travel booking experience with flexible payment options including crypto, loyalty points, and traditional cards. The platform's competitive advantage lies in its extensive inventory, exclusive wallet-only discounts, and NFT rewards program, appealing to a growing segment of crypto users and Web3 travelers. Partnerships with notable blockchain and crypto brands enhance its market credibility. Revenue streams likely include commissions from bookings and possibly NFT sales or rewards. The company targets tech-savvy travelers seeking innovative payment methods and rewards. Growth indicators include active marketing via social media and tracking pixels, and endorsements from public figures. The ecosystem includes community engagement through Discord and Twitter. Strategic observations suggest continued expansion of crypto payment options and NFT utilities could strengthen market position.

Security posture

Sleap.io exhibits a solid security posture with mandatory HTTPS, domain transfer lock, and cookie consent mechanisms aligned with GDPR. The absence of DNSSEC is a minor gap in DNS security. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. The use of multiple third-party tracking scripts introduces a moderate privacy risk but is managed with consent banners. Lack of a published security policy or incident response contacts limits transparency and readiness perception. No security.txt file or vulnerability disclosure program was found, which could be improved to foster responsible vulnerability reporting. Overall, the platform balances usability and security well but should enhance formal security documentation and DNS protections to elevate trust and compliance.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS integrity and prevent spoofing.
  2. Publish a security.txt file to provide clear vulnerability disclosure guidelines.
  3. Create and publish a dedicated security policy page outlining security practices and incident response procedures.
  4. Add explicit incident response contact channels such as security@ or abuse@ email addresses.
  5. Regularly audit and update third-party scripts to minimize potential vulnerabilities and privacy risks.

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.
