0–100, higher is better. How it is calculated

Fastmail Pty Ltd operates a professional email and calendar service focused on privacy and security. Their website, fastmail.help, serves as a comprehensive help center powered by Zendesk, providing extensive user support, documentation, and resources. The company targets both individual users and businesses seeking secure and reliable email solutions, positioning itself as a privacy-conscious alternative in the email service market. The site features clear navigation, well-organized content, and strong branding consistency, enhancing user experience and trust. Technically, the website leverages modern web technologies including jQuery, Highlight.js, and Zendesk's Help Center platform. It is hosted on Zendesk infrastructure, ensuring reliable performance and mobile optimization. While performance is moderate, the site is accessible and SEO-friendly with good accessibility features. However, explicit security headers are not evident in the HTML content, which could be improved. From a security perspective, the site enforces HTTPS and promotes a bug bounty program, reflecting a proactive security stance. No vulnerabilities or exposed sensitive data were detected in the content. Privacy compliance is indicated by the presence of a comprehensive privacy policy and terms of service, though a cookie consent mechanism is absent. Incident response contact details are not directly provided, which could be enhanced for better transparency. Overall, the website demonstrates a high level of professionalism, security awareness, and user-centric design. The domain registration data aligns well with the business identity, supporting legitimacy. Strategic recommendations include implementing security headers, publishing a security.txt file, enhancing incident response visibility, and adding cookie consent mechanisms to strengthen compliance and trust.

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 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

Fastmail operates in the technology sector, providing subscription-based email and calendar services with a strong emphasis on privacy and security. Their market positioning is that of a trusted, privacy-focused email provider catering to both individual and business users. The business model relies on recurring revenue from subscriptions. The company maintains a robust partnership ecosystem, including app store presence and social media engagement. Growth indicators include comprehensive support resources and active security programs. The company’s operations are transparent with consistent branding and a clear value proposition centered on secure communication.

Security posture

The security posture of the Fastmail help website is solid, with HTTPS enforced and no visible exposure of sensitive data. The presence of a bug bounty program indicates an active approach to vulnerability management. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options suggests room for improvement. Incident response information is not prominently available, and no direct security contact emails are provided. The site does not display a cookie consent banner, which may be a compliance gap. Overall, the security maturity is good but could be enhanced with additional headers and clearer incident response channels.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a security.txt file at the root domain to facilitate responsible vulnerability disclosure and improve transparency.
  3. Provide direct contact information for security incidents, such as a dedicated security@ or abuse@ email address.
  4. Add a cookie consent mechanism to comply fully with GDPR and other privacy regulations.
  5. Enhance the visibility of incident response policies and procedures on the website to build user trust.

Technical notes

Notes

The website is built on the Zendesk Help Center platform, utilizing modern JavaScript libraries such as jQuery, Highlight.js, and Magnific Popup for enhanced user interaction. The tech stack supports responsive design and accessibility features, ensuring good mobile optimization and user experience. Hosting is managed by Zendesk, providing reliable uptime and performance. The site’s SEO is well-implemented with proper meta tags and structured navigation. However, the performance is moderate, suggesting potential optimization opportunities. The absence of some security headers and cookie consent mechanisms indicates minor technical debt in security and compliance areas.
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.
