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

Kerlink is a leading provider of IoT connectivity equipment, software, and services, specializing in LoRaWAN technology for public and private networks. The company targets businesses, cities, industries, and network operators globally, offering a comprehensive portfolio including outdoor and indoor gateways, network servers, management tools, and value-added IoT applications. Their market position is strong, supported by their role as a founding member of the LoRa Alliance and their listing on the Euronext Growth market. The website reflects a mature digital presence with professional design, clear navigation, and extensive content relevant to their industry. Technically, the site is built on WordPress with WooCommerce, integrating modern analytics and marketing tools, and optimized for mobile and SEO. Security posture is good with HTTPS enforced and cookie consent implemented, though some security headers could be improved. The absence of WHOIS registration data is a notable gap but does not detract significantly from the overall legitimacy given the professional web presence and business indicators. Strategic recommendations include enhancing security headers, publishing a dedicated security policy, and adding a security.txt file to improve vulnerability reporting 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

3 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"

  2. 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

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

Kerlink operates in the technology and telecommunications sectors with a focus on IoT connectivity solutions. Their business model is B2B, providing hardware, software, and services that enable IoT network deployment and management. The company leverages partnerships and industry alliances, such as the LoRa Alliance, to strengthen its ecosystem. Revenue streams likely include product sales, subscription services (e.g., Maintain Program), and professional services. The website content and downloadable success stories indicate a broad target market across smart cities, agriculture, industry, and building management. Growth indicators include active event participation and continuous content updates. The partnership ecosystem is robust, with multiple references and alliances highlighted. Overall, Kerlink demonstrates a well-structured operation with clear market positioning and strategic partnerships.

Security posture

Kerlink's website demonstrates a solid security foundation with HTTPS enforced and a cookie consent mechanism aligned with GDPR requirements. The presence of a vulnerability disclosure page indicates awareness and readiness to handle security incidents. However, explicit security headers such as X-Frame-Options and X-Content-Type-Options are not evident in the HTML, suggesting room for improvement. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. The absence of a published security policy and security.txt file limits transparency and automated vulnerability reporting capabilities. Overall, the security maturity is good but could be enhanced by adopting additional best practices and formal documentation.

Recommendations

  1. Implement and enforce security headers like X-Frame-Options and X-Content-Type-Options to mitigate clickjacking and MIME sniffing risks.
  2. Publish a dedicated security policy page outlining security practices, incident response, and data protection measures.
  3. Create and host a security.txt file to facilitate responsible vulnerability disclosure and improve trust with security researchers.
  4. Enhance WHOIS transparency by ensuring domain registration details are publicly available or justified if privacy protection is used.
  5. Regularly audit third-party scripts and analytics tools to minimize privacy risks and ensure compliance with evolving regulations.

It uses up-to-date versions of jQuery and integrates multiple analytics and marketing tools including Google Analytics, Google Tag Manager, HubSpot, and LinkedIn Insight. The site is mobile-optimized with responsive images and accessible navigation. Performance is moderate, likely influenced by multiple external scripts and rich media content. SEO is well implemented with canonical tags, Open Graph metadata, and JSON-LD structured data for enhanced search engine understanding.

Overall, the technical infrastructure supports a professional and scalable web presence aligned with business goals.
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.
