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.

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 · found on this site
  • 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

Mistertango operates in the European financial services sector, focusing on business banking with a digital-first approach. Its competitive advantages include multi-currency accounts, low-cost SEPA and SWIFT payments, and instant issuance of virtual cards. The business model relies on subscription plans and transaction fees. The company targets SMEs and startups across Europe, emphasizing compliance and licensing as trust factors. The presence of customer testimonials and social media engagement supports its market credibility. The lack of visible phone contact and incomplete WHOIS data suggest areas for operational transparency improvement. The company leverages HubSpot for marketing and customer engagement, indicating a mature digital marketing strategy.

Security posture

The website enforces HTTPS and uses a cookie consent banner, reflecting compliance with privacy regulations. Multiple third-party analytics and tracking scripts are present, which increases the attack surface but are standard for marketing-driven sites. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. Security headers like Content-Security-Policy and X-Frame-Options are not explicitly found, representing an opportunity for enhancement. The absence of a published security policy or incident response contact limits transparency in security governance. Overall, the security posture is solid but could be improved with additional headers and explicit security documentation.

Recommendations

  1. Publish domain registration details or ensure WHOIS data is publicly available to improve legitimacy trust.
  2. Implement and enforce Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options headers.
  3. Provide a dedicated security policy page and incident response contact information.
  4. Review and audit third-party scripts regularly to minimize security risks.
  5. Enhance accessibility features and provide more explicit privacy compliance disclosures.

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.
