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

5 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. 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

Taxwire operates in the technology and finance sectors, offering SaaS solutions for sales tax compliance automation. Their business model combines software with expert tax services, appealing to finance teams and operators in fast-growing companies. The company leverages integrations with billing, commerce, and accounting platforms to streamline tax processes. Their competitive advantage lies in end-to-end coverage, expert support, and accurate rooftop-level tax calculations. The presence of detailed onboarding and customer testimonials indicates a customer-centric approach. Partnerships with platforms like Notion and founder blogs suggest an engaged ecosystem. The lack of explicit company registration details and WHOIS data warrants further verification but does not undermine the operational insights derived from the website.

Security posture

The website employs HTTPS and uses Google Tag Manager for controlled script management, indicating a baseline security awareness. However, no explicit security headers such as Content-Security-Policy or X-Frame-Options were detected, which are recommended best practices. There is no visible incident response or security policy page, nor a vulnerability disclosure or security.txt file, which could enhance transparency and trust. No sensitive data exposure or vulnerable libraries were found in the HTML content. The site lacks a cookie consent mechanism, which is important for GDPR compliance given the European user base implied by global tax services. Overall, the security posture is good but could be improved with additional headers, policies, and privacy controls.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Add a cookie consent banner or mechanism to comply with GDPR and other privacy regulations.
  3. Publish a dedicated security policy and incident response page to improve transparency and user trust.
  4. Consider adding a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  5. Verify and update WHOIS domain registration information to ensure domain legitimacy and reduce suspicion.

Technical notes

Notes

The website is built using Webflow CMS, leveraging modern JavaScript libraries such as jQuery and Swiper.js for UI interactions. Google Tag Manager is used for analytics and marketing scripts, including tracking pixels from Swan and B2BJS. The site loads fonts from Google Fonts and assets from a CDN hosted on Amazon CloudFront, contributing to fast performance. The HTML is well-structured with proper meta tags for SEO and social sharing (Open Graph and Twitter cards). Mobile optimization and accessibility are well addressed. No CMS other than Webflow is detected. The site does not expose any sensitive data or use outdated libraries. Technical debt appears low, and the infrastructure is modern and scalable. Opportunities exist to enhance security headers and privacy mechanisms.
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.
