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

Freron Software operates the website freron.com, promoting MailMate, a specialized IMAP email client for macOS. The company targets advanced macOS users who require powerful email management features including encryption, advanced search, and integration capabilities. The business model is based on software licensing and product sales, positioning itself as a niche player in the macOS email client market. The website content is professional, well-structured, and consistent with the brand identity, reflecting a small but focused software company based in Denmark. Technically, the website is a straightforward static HTML/CSS site with no detected complex frameworks or CMS. It is hosted under a registrar known for domain services, with no DNSSEC enabled and no advanced security headers detected. The site performs well with basic mobile optimization and accessibility features. There is no evidence of tracking or advertising scripts, indicating a privacy-conscious approach. From a security perspective, the domain is stable and long-lived, registered since 2010 with clientTransferProhibited status, enhancing domain security. However, the lack of DNSSEC and missing security headers are areas for improvement. No explicit security policies or incident response contacts are published, and cookie consent mechanisms are absent, which may impact compliance with privacy regulations. Overall, the website presents a low-risk profile with a solid business credibility score but could benefit from enhanced security and privacy compliance measures to strengthen trust and regulatory adherence.

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

6 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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

Freron Software's MailMate product serves a niche market of macOS users seeking advanced email client features. The company leverages a direct sales model with licensing, supported by a professional website and active blog updates indicating ongoing product development. The market positioning is specialized rather than mass-market, focusing on power users valuing keyboard control, encryption, and integration. The company appears small, with no subsidiaries or parent company indicated. The partnership ecosystem is minimal, with external links primarily to social media and product documentation. Growth indicators include recent blog posts and beta releases, suggesting active development and user engagement.

Security posture

The security maturity level is moderate. The domain registration is stable and trustworthy, but technical security controls on the website are minimal. Absence of DNSSEC, security headers, and published security policies limits the security posture. No vulnerability disclosures or incident response contacts are provided, which may hinder rapid response to security events. The lack of cookie consent and privacy compliance features indicates potential GDPR compliance gaps. No exposed sensitive data or vulnerable libraries were detected. Overall, the security culture appears basic but could be improved with formal policies and technical enhancements.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and integrity.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a dedicated security policy and incident response contact information on the website.
  4. Add a cookie policy and consent mechanism to comply with privacy regulations.
  5. Enhance website accessibility and mobile optimization to improve user experience and SEO.

Technical notes

Notes

The website uses a simple, static HTML and CSS technology stack without detected JavaScript frameworks or CMS. Hosting is via a registrar-associated provider with no advanced hosting platform detected. Performance is fast due to minimal content and static delivery. SEO is basic with proper meta tags but no Open Graph or JSON-LD structured data found. Accessibility and mobile optimization are basic but functional. Technical debt is low given the simple architecture, but modernization opportunities include adding structured data, security headers, and privacy compliance features. The lack of analytics or tracking reduces complexity but also limits marketing insights.
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.
