Risk levelLow

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

Fastmail Pty Ltd operates a professional email and calendar hosting service focused on privacy, security, and productivity for individuals and businesses. The company positions itself as an independent alternative to major providers like Gmail and iCloud, emphasizing no ads, no data mining, and strong user control. The website is well-designed, mobile-optimized, and rich in content that clearly communicates the business value and service features. Technical infrastructure leverages modern web technologies with fast performance and good accessibility, although explicit security headers are not evident in the HTML source. The security posture is strong with HTTPS enforced, a bug bounty program, and clear incident response channels, but could be improved by publishing a security.txt file and adding more visible certifications. Privacy compliance is robust with comprehensive privacy and cookie policies and GDPR adherence. WHOIS data for the domain is unavailable from the provided raw output, which is unusual and reduces transparency, but the website content and external presence strongly indicate legitimacy. Overall, the site scores well on content quality, technical implementation, security, privacy, and business credibility, making it a trustworthy and professional service provider.

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

3 findings rated critical or high. Fix these first.

  1. 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

  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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 paid subscription email and calendar hosting services. It targets privacy-conscious individuals and businesses seeking alternatives to large tech providers. The company has a strong market position with over 20 years of service and a reputation for security and privacy. Its business model is subscription-based, with key services including email hosting, calendar integration, contacts management, aliasing, and migration tools. The company maintains an active presence on social media and invests in open standards and open source contributions, enhancing its industry credibility. The lack of WHOIS transparency is a minor concern but does not detract significantly from its established brand and customer trust. The company does not publicly list phone numbers or physical addresses on the main site, relying instead on online support channels and contact forms.

Security posture

Fastmail demonstrates a mature security posture with HTTPS enforced site-wide, a dedicated security page, and a bug bounty program for vulnerability reporting. The site avoids exposing sensitive data and provides personal support 24/7. However, the absence of explicit security headers such as Content-Security-Policy and the lack of a published security.txt file are areas for improvement. No known vulnerabilities or malware indicators were detected in the site content or scripts. Privacy policies are comprehensive and GDPR compliant, supporting strong data protection practices. Incident response contact channels include security-related email addresses. Overall, the security maturity is high but could be enhanced with additional visible security best practices and certifications.

Recommendations

  1. Implement and publish a security.txt file to facilitate vulnerability disclosure.
  2. Add explicit security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security.
  3. Display security certifications or compliance badges prominently on the website.
  4. Consider publishing verified company contact phone numbers and physical address to enhance transparency.
  5. Regularly audit third-party scripts and tracking pixels to minimize privacy risks.

Technical notes

Notes

The website uses modern web technologies including HTML5, CSS, JavaScript, and web fonts (Proxima Nova and Roca). It employs SVG graphics for logos and icons, enhancing scalability and performance. The site is mobile-optimized with responsive design and good accessibility features. Performance is fast with preloading of fonts and images. No CMS or hosting provider information is explicitly detected. Analytics and tracking scripts are present but limited to event tracking and dead-click capture, indicating moderate user tracking. SEO is supported by proper meta tags and Open Graph data. The lack of JSON-LD structured data is a minor SEO opportunity. Overall, the technical implementation is solid with room for minor enhancements in security headers and structured data.
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.
