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

ello Mail is a Swiss-based webmail service platform providing users with email access and management capabilities through a web interface. The website primarily serves as a login portal for users to access their email accounts. The platform uses the Roundcube webmail system with custom skins and scripts to deliver its service. The target audience is general users requiring secure and reliable email services. The business model is focused on providing webmail hosting and management, with no explicit information on market positioning or company size. Technically, the website employs standard web technologies including jQuery, Bootstrap, and Google Fonts, delivering a basic but functional user experience. Mobile optimization and accessibility are present but minimal, and SEO practices are basic. Security posture shows use of HTTPS and secure login forms with CSRF tokens; however, no advanced security headers or policies are detected, and privacy and cookie policies are absent, which may impact user trust and compliance. No contact information or social media presence is visible on the login page, limiting transparency. Overall, the website is functional but lacks comprehensive privacy, security, and business information disclosures.

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

8 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.

    • 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
    • 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

  2. GDPR outside view

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

The business operates in the technology sector as a webmail service provider based in Switzerland. The lack of detailed company information, privacy policies, and contact details suggests a small-scale operation or a service primarily targeted at existing customers rather than public marketing. The presence of related domains ello.ch and myello.ch indicates a partnership or ecosystem of related services. The business model likely revolves around providing email hosting and management services, possibly for a niche or regional market. There is no evidence of advertising, affiliate programs, or extensive marketing tools, indicating a focus on service delivery rather than customer acquisition through digital marketing. Growth indicators and strategic partnerships are not evident from the provided data.

Security posture

The security posture of the website is moderate. The site uses HTTPS, ensuring encrypted communication, and implements secure login forms with CSRF tokens. However, the absence of common security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces protection against common web attacks. No vulnerability disclosure or incident response policies are visible, and no security certifications are mentioned. The lack of privacy and cookie policies also indicates potential compliance gaps with GDPR and other data protection regulations. The site does not appear to use tracking or analytics scripts that could expose user data. Overall, while basic security measures are in place, there is room for significant improvement in security best practices and transparency.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve compliance and user trust.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  3. Provide clear contact information and incident response channels to improve transparency and support.
  4. Conduct regular security audits of third-party libraries and update them to mitigate vulnerabilities.
  5. Enhance mobile optimization and accessibility to improve user experience across devices.

Technical notes

Notes

The website is built on a standard webmail platform (Roundcube) customized with Bootstrap and jQuery for UI enhancements. It uses multiple Google Fonts for typography and custom CSS for branding. The login form uses POST method with CSRF tokens, indicating attention to form security. Performance is moderate with no explicit indicators of slow loading, but mobile optimization and accessibility are basic. No CMS or hosting provider information is detected. The absence of SEO metadata and structured data limits search engine visibility. The technical stack is stable but could benefit from modernization and improved security configurations.
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.
