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

      GDPR requires a clear and accessible privacy policy

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

Adulto operates a B2B business model offering pay-per-verification age verification solutions to online retailers. Their competitive advantage lies in their extensive network of partner e-shops, ISO 27001 certification, and partnerships with major banks for bank identity verification. The company targets online sellers of tobacco, alcohol, CBD, pyrotechnics, and adult products, addressing a critical compliance need in the Czech market. Growth indicators include rapid adoption, integration plugins for popular e-commerce platforms, and continuous service enhancements such as multi-age verification. Strategic partnerships with Bankovní identita and membership in APEK association further strengthen their market position.

Security posture

Adulto demonstrates a mature security posture with HTTPS enforced, strong security headers, and ISO 27001 certification. The service uses sandboxed iframes for verification widgets, minimizing risk exposure. No vulnerabilities or exposed sensitive data were detected in the website content. However, the absence of a visible cookie consent mechanism and lack of published incident response contacts or security.txt file indicate areas for improvement in compliance and transparency. Overall, the security practices align well with industry standards for a service handling sensitive identity verification data.

Recommendations

  1. Implement a visible cookie consent banner and detailed cookie policy to ensure full GDPR compliance.
  2. Publish incident response contact information and consider adding a security.txt file to facilitate vulnerability reporting.
  3. Regularly review and update security headers and SSL configurations to maintain high security standards.
  4. Enhance privacy compliance by clearly communicating data retention policies and user rights.
  5. Continue expanding integration options and partnerships to strengthen market position and service reliability.

Technical notes

Notes

The website is built using modern web technologies including HTML5, CSS3, JavaScript, and Bootstrap framework. It leverages Google Fonts and Cloudflare DNS services for performance and reliability. The site is mobile-optimized with excellent accessibility features meeting WCAG 2.1 standards. Performance is fast with no broken elements detected. SEO is well addressed with proper meta tags and Open Graph data. The technical infrastructure supports scalability, handling up to 50 verifications per minute with capacity for much more. Opportunities exist to improve privacy compliance mechanisms and incident response visibility.
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.
