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

SerNet, Inc. is a technology company specializing in providing commercial open source alternatives to Microsoft Windows through its flagship product SAMBA+. The company operates as a US subsidiary of the German SerNet GmbH and offers software subscriptions, support services, and SLAs targeting enterprise customers, OEMs, and startups. Their market position is well-established with over 25 years of experience supporting open source Samba, serving a diverse client base including Fortune 500 companies. The website is professionally designed, content-rich, and clearly communicates their business offerings and expertise. Technically, the site is built on TYPO3 CMS, uses Matomo for analytics, and is mobile optimized with good SEO practices. Security posture is solid with HTTPS and cookie consent mechanisms, though it lacks some advanced security headers and public incident response information. The missing WHOIS data for the domain www.sernet.com introduces some uncertainty regarding domain legitimacy, but the overall business credibility and online presence are strong. Strategic recommendations include enhancing security headers, publishing vulnerability disclosure policies, and improving accessibility features to further strengthen trust and compliance.

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.

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

SerNet operates in the technology sector focusing on identity and access management and SMB server solutions for enterprise Linux and IBM AIX platforms. Their business model revolves around software subscriptions and support services, including SLAs. The company targets enterprise clients, OEMs, and startups, leveraging a long-standing reputation in the Samba open source community. Their partnership ecosystem includes related domains such as samba.plus and verinice.com, enhancing their product and service offerings. The US subsidiary was founded in 2021 to better serve the American market, complementing the parent company's presence since 2004. The website reflects a mature digital presence with consistent branding and professional content, supporting their market positioning as a trusted open source software provider.

Security posture

The website enforces HTTPS and implements a cookie consent banner, indicating awareness of privacy and security best practices. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security posture. No incident response or vulnerability disclosure information is publicly available, which could hinder rapid response to security events. The site does not expose sensitive data or use vulnerable libraries visibly, and forms appear to be secured with CAPTCHA and consent checkboxes. Overall, the security maturity is moderate with room for improvement in header implementation and transparency around incident handling.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to mitigate common web vulnerabilities.
  2. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  3. Provide public incident response contact information to improve transparency and readiness.
  4. Enhance website accessibility features to comply with WCAG standards and improve user experience for all users.
  5. Regularly audit third-party scripts and analytics tools to ensure no vulnerabilities or privacy issues.

Technical notes

Notes

The website is built on TYPO3 CMS, a mature and extensible content management system, indicating a stable technical foundation. The use of Matomo analytics reflects a privacy-conscious approach to user tracking. The site is mobile optimized and includes SEO best practices such as meta tags and Open Graph data. Performance is moderate with asynchronous script loading and compressed assets. However, the lack of explicit security headers and incomplete WHOIS data suggest areas for technical improvement. Hosting provider details are not disclosed, and no advanced platform or cloud service indicators were detected. Overall, the technical infrastructure supports the business needs but could benefit from enhanced security and transparency measures.
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.
