Risk levelLow

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

Fastmail Pty Ltd operates a professional, privacy-focused email and calendar hosting service targeting both individuals and businesses. The company positions itself as a secure, ad-free alternative to major providers like Gmail and iCloud, emphasizing privacy, productivity, and ease of use. Their service includes native apps across platforms and a strong commitment to open standards and open source contributions. The website reflects a mature digital presence with excellent design, clear navigation, and comprehensive content supporting their business model. Technically, the website employs modern web technologies including JavaScript, SVG icons, and web fonts, delivering a fast and mobile-optimized experience. The presence of security headers and HTTPS indicates a strong security posture. The company also maintains a bug bounty program and provides clear channels for reporting security issues, demonstrating a proactive approach to security management. Despite the strong website and business presence, the absence of WHOIS registration data is a notable gap, reducing transparency and slightly impacting trustworthiness. However, the overall security and privacy focus, combined with positive customer testimonials and no detected vulnerabilities, suggest a low risk profile. Strategically, Fastmail should consider publishing a security.txt file to facilitate vulnerability disclosures and enhance incident response visibility. Continued emphasis on privacy compliance and transparent business information will further strengthen their market position.

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 as a paid subscription email and calendar hosting provider with a medium-sized business footprint based in Australia. Their competitive advantage lies in privacy, security, and independence from large tech ecosystems. The business model relies on subscription revenue, targeting privacy-conscious users and businesses seeking alternatives to mainstream providers. Their ecosystem includes native apps and support for open standards like JMAP. Partnerships are not explicitly listed, but the company maintains a presence on major social platforms and contributes to open source projects. Growth indicators include over 20 years of operation and positive user testimonials. Strategic observations highlight their focus on privacy as a key differentiator and their commitment to open internet standards.

Security posture

Fastmail demonstrates a mature security posture with HTTPS enforcement, comprehensive security headers, and a bug bounty program. The website encourages reporting of security issues and provides dedicated support channels. No vulnerabilities or exposed sensitive data were detected in the website content. Privacy policies are comprehensive and GDPR compliant, and tracking is minimal or absent. However, the lack of WHOIS transparency is a minor concern. Incident response readiness appears adequate, though a security.txt file is not present. Overall, the company shows strong security culture and practices aligned with industry expectations for a privacy-focused email provider.

Recommendations

  1. Publish a security.txt file to improve vulnerability disclosure processes.
  2. Increase visibility of incident response contacts on the website.
  3. Consider obtaining and displaying recognized security certifications (e.g., ISO 27001).
  4. Enhance WHOIS transparency or provide domain registration details to improve trust.
  5. Maintain and expand open source contributions to reinforce market differentiation.

Technical notes

Notes

The website uses modern web standards including HTML5, CSS3, and JavaScript with SVG icons and custom web fonts for a polished user experience. It is mobile-optimized and performs well with fast loading times. The absence of a detected CMS suggests a custom or static site architecture. Security headers and HTTPS are properly configured, contributing to a secure browsing environment. Analytics usage is minimal and privacy-conscious, employing PostHog with event tracking but no invasive tracking pixels. The technical infrastructure supports a professional and secure service delivery, though hosting provider details are not disclosed.
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.
