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

Filemail Inc. operates a mature and professional cloud-based file transfer service specializing in sending and sharing large files securely. The company targets a broad audience including individuals, teams, businesses, and enterprises, offering a free tier and multiple paid subscription plans with advanced features such as managed file transfer, compliance certifications, and custom branding. The website demonstrates a strong market position with over 50 million users and global data centers, emphasizing security and ease of use. Technically, the website is built on modern frameworks like Next.js and React, with native applications available across major platforms including desktop, mobile, and Outlook. The site is well-optimized for performance, mobile responsiveness, accessibility, and SEO. Security is robust with HTTPS, multiple security headers, end-to-end encryption, 2FA, virus scanning, and regular penetration testing. The security posture is strong, with compliance to standards such as ISO 27001, HIPAA, GDPR, and Cyber Essentials UK. However, explicit incident response and vulnerability disclosure policies are not publicly found, representing an area for improvement. The absence of WHOIS data limits domain registration trust analysis, but the overall business credibility and website professionalism mitigate concerns. Overall, Filemail presents a low-risk profile with a secure, compliant, and user-friendly service offering. Strategic recommendations include publishing incident response and vulnerability disclosure policies, adding a security.txt file, and providing Data Protection Officer contact details to enhance transparency 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

5 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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

Filemail is positioned as a leading secure file transfer service with a subscription-based SaaS model. Its competitive advantages include support for unlimited file sizes, multi-platform native apps, strong security and compliance certifications, and customization options for enterprises. Revenue streams derive from tiered paid plans catering to individuals, professionals, businesses, and large enterprises. The target customer segments range from casual users needing free transfers to regulated industries requiring compliance and audit capabilities. The company demonstrates growth through a large user base, extensive data transfer volumes, and global infrastructure. Partnerships and integrations, such as Outlook plugins and API offerings, expand its ecosystem and market reach.

Security posture

Filemail exhibits a mature security posture with multiple layers of protection including HTTPS, strong encryption (TLS 1.2 with AES-256), end-to-end encryption, 2-factor authentication, password protection, and virus scanning. The company conducts regular penetration testing and maintains compliance with major security frameworks such as ISO 27001 and HIPAA. Audit trails and file activity tracking enhance accountability. However, the lack of publicly available incident response and vulnerability disclosure policies may limit transparency and responsiveness to security events. No vulnerabilities or exposed sensitive data were detected in the website content. Overall, the security culture appears robust and aligned with industry best practices.

Recommendations

  1. Publish a formal incident response policy and make it accessible on the website.
  2. Implement and publicize a vulnerability disclosure program, including a security.txt file.
  3. Provide contact information for the Data Protection Officer to enhance GDPR transparency.
  4. Maintain and regularly update security certifications and penetration testing reports.
  5. Enhance user education on security features and best practices through the website and apps.

Technical notes

Notes

The website leverages a modern technology stack centered on React and Next.js, enabling server-side rendering and optimized performance. It uses Google Tag Manager for analytics and marketing integration. The site is mobile-optimized with responsive design and accessibility considerations. Hosting appears to be on a proprietary or dedicated infrastructure with global CDN support, ensuring fast transfer speeds and reliability. The technical implementation is clean with valid HTML and CSS, and no broken elements detected. Opportunities exist to further enhance technical transparency by publishing detailed security and privacy documentation.
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.
