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

  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

Tangany operates a B2B SaaS model focused on regulated digital asset custody, leveraging partnerships with major financial institutions and brokers such as FlatexDegiro, Bitvavo, and eToro. The company emphasizes compliance and security, catering to regulated entities and fintechs seeking to integrate digital assets securely. Their award-winning platform and BaFin license provide competitive advantages in the European market. Tangany's growth is supported by a cloud-based infrastructure and a flexible API-first approach, enabling seamless integration and scalability. The company targets medium-sized enterprises and institutional clients, with a clear focus on regulatory adherence and technological innovation.

Security posture

Tangany demonstrates a mature security posture with HTTPS enforced, domain registration locked with EPP status codes, and custody security based on HSM and MPC technologies. The website shows no signs of vulnerabilities or exposed sensitive data. However, DNSSEC is not enabled, and explicit security policies or incident response contacts are not publicly available. The company complies with GDPR and provides cookie consent mechanisms. Overall, Tangany maintains strong security practices appropriate for a regulated financial service provider but could improve transparency around security policies and vulnerability disclosure.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Publish a dedicated security policy and incident response contact information on the website.
  3. Implement a security.txt file to facilitate responsible vulnerability disclosure.
  4. Consider providing direct company contact emails or phone numbers for customer support and compliance inquiries.
  5. Maintain regular security audits and update website content to reflect ongoing compliance and security improvements.

The website is built on a modern tech stack using Next.js and React, hosted on Microsoft Azure as inferred from DNS servers. It uses DatoCMS for content management and delivers fast, mobile-optimized, and accessible user experiences. The site includes comprehensive meta tags and Open Graph data for SEO and social sharing. Performance is fast with no broken elements detected. The technical infrastructure supports scalability and integration with client systems via APIs. There are no detected technical debts or outdated libraries, indicating a well-maintained platform.
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.
