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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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. 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
    • High

      SSL Certificate Expires Soon

      SSL certificate expires in 19 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

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

Fonoa operates in the technology sector, providing SaaS solutions for global tax compliance automation. Their market positioning emphasizes continuous compliance and real-time tax intelligence, appealing to medium to large enterprises with complex tax needs. The company showcases partnerships with notable brands such as Uber, Zoom, and Netflix, enhancing credibility. Their business model focuses on B2B SaaS with key revenue streams likely from subscription-based services and API integrations. The website content highlights scalability, flexibility, and AI-powered tax intelligence as competitive advantages. The absence of public WHOIS data suggests privacy protection or recent domain registration, which is not uncommon for tech startups or privacy-conscious companies. The company maintains a strong ecosystem of resources, including blogs, webinars, and customer stories, supporting customer education and engagement.

Security posture

The website demonstrates a solid security posture with enforced HTTPS, comprehensive security headers, and a dedicated security page outlining platform security measures. Cookie consent and privacy policies indicate GDPR compliance and user data protection awareness. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of explicit incident response contacts and vulnerability disclosure policies represents a gap in transparency and readiness communication. The use of multiple third-party analytics and marketing scripts necessitates ongoing monitoring to mitigate supply chain risks. Overall, the security maturity is good but could be enhanced by publishing incident response details and adopting a formal vulnerability disclosure program.

Recommendations

  1. Publish clear incident response contact information and procedures on the website.
  2. Implement and publicize a vulnerability disclosure policy or security.txt file.
  3. Regularly review and audit third-party scripts and tracking tools for security risks.
  4. Consider appointing and publishing Data Protection Officer contact details if applicable.
  5. Enhance transparency around certifications and compliance frameworks to boost trust.

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.
