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

The Mail Archive is a specialized service that provides searchable archives for mailing lists, enabling users and administrators to easily search through archived mailing list postings. Established in 1998, it holds a niche position in the technology sector, focusing on mailing list archiving services. The website presents a straightforward interface with basic but functional design and navigation, targeting mailing list users and administrators. Technically, the site uses standard web technologies including HTML5, CSS, and JavaScript, with DNS hosted via Cloudflare. The site shows moderate performance and basic mobile optimization. There is no evidence of advanced frameworks or CMS usage. Security practices include HTTPS usage and domain transfer protection, but DNSSEC is not enabled and security headers are absent, indicating room for improvement. From a security perspective, the website does not expose sensitive data and uses HTTPS, but lacks visible security headers and cookie consent mechanisms. There is no published security policy or incident response information, which could be enhanced to improve trust and compliance. The domain registration is consistent and long-standing, supporting legitimacy. Overall, the website is functional and trustworthy for its niche purpose but would benefit from enhanced security headers, privacy compliance improvements, and clearer contact and security policy disclosures to strengthen its security posture and user 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

7 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 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';…

  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

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 Mail Archive operates in the technology sector, providing a unique service that archives mailing list communications and makes them searchable. Its business model revolves around integrating with mailing lists as a member to archive messages. The service targets mailing list administrators and users who require searchable archives. The domain's long registration history since 1998 indicates stability and experience. The website links to multiple well-known open source and community mailing lists, suggesting a strong presence in open source ecosystems. There is no indication of monetization through advertising or affiliate programs, implying a service-focused or community-supported model. The lack of explicit contact information or business registration details limits deeper business intelligence insights.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and domain transfer protection in place. However, the absence of DNSSEC and security headers such as Content-Security-Policy or X-Frame-Options reduces its defense-in-depth. No incident response or security policies are published, and no contact channels for security issues are provided. The lack of cookie consent mechanisms also indicates incomplete privacy compliance. No vulnerabilities or exposed sensitive data were detected in the content. Overall, the security maturity is basic and could be improved by implementing recommended security headers, enabling DNSSEC, and publishing security and incident response policies.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Add a cookie consent mechanism to comply with privacy regulations.
  4. Publish clear security policies and incident response contact information.
  5. Provide explicit contact information to improve trust and user support.

Technical notes

Notes

The website uses a simple technology stack with HTML5, CSS, and JavaScript. It relies on Cloudflare for DNS services but does not enable DNSSEC. The site lacks modern frameworks or CMS platforms, indicating a lightweight and possibly custom-built solution. Performance is moderate with basic mobile optimization and accessibility features. SEO is basic with appropriate meta tags and Open Graph data. There is no evidence of analytics or tracking scripts, which reduces privacy concerns but also limits marketing insights. The site could benefit from modernization to improve mobile responsiveness, accessibility, and security features.
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.
