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

Kersten Group is a global leader specializing in the production of custom curved components and constructions in steel and aluminium. Their website highlights their expertise in bending and processing metal tubes, sections, and plates, serving diverse industries such as offshore, energy, mobility, machinery, architecture, medical, and industrial equipment. The company positions itself as an innovator focused on creating what seems impossible by combining technology, skill, and partnerships to deliver strength, elegance, efficiency, and sustainability in their products. Technically, the website is built on Syveon CMS 4.2.0 and employs modern web technologies including Google Analytics, Google Tag Manager, Leadinfo tracking, and Vimeo for video content. The site is well-optimized for mobile devices, has good SEO practices, and provides a professional user experience with clear navigation and comprehensive content. Cookie consent mechanisms and a detailed privacy policy indicate attention to privacy compliance. From a security perspective, the site uses HTTPS and has implemented cookie consent, but lacks explicit security headers and a published security policy or incident response contact. No vulnerabilities or exposed sensitive data were detected in the HTML content. The WHOIS data for the domain is missing or unavailable, which raises some concerns about domain registration transparency, though the website content and social media presence support its legitimacy. Overall, the website demonstrates a strong digital presence and professional business operation with moderate security posture. Strategic recommendations include enhancing security headers, publishing a security policy or incident response contact, and improving domain registration transparency to 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.

Priority findings

4 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 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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

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

Kersten Group operates in the manufacturing sector with a focus on custom curved metal components for multiple industries including energy, transportation, architecture, and medical. Their business model centers on engineering and manufacturing bespoke steel and aluminium products, leveraging advanced bending and processing technologies. The company targets industrial clients requiring high-quality, durable, and aesthetically pleasing metal constructions. Their market position as a global leader is supported by certifications and a broad international presence. The website content and social media channels indicate active engagement and a commitment to sustainability and quality. Revenue streams likely derive from manufacturing contracts, co-engineering services, and assembly solutions. The company maintains partnerships with design and engineering firms, as suggested by their co-engineering offerings and collaborations. Growth indicators include ongoing projects, news updates, and expansion announcements. The company’s operations appear well-structured with a focus on innovation and customer-centric solutions.

Security posture

The website exhibits a moderate security maturity level. HTTPS is enforced, and cookie consent mechanisms are in place, reflecting compliance with privacy regulations such as GDPR. However, the absence of key security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options suggests room for improvement in mitigating common web vulnerabilities. No explicit security policy or incident response contact information is published, which could hinder effective vulnerability reporting and incident management. The lack of a security.txt file further limits transparency in vulnerability disclosure. No exposed sensitive data or vulnerable libraries were detected in the analyzed HTML content. Overall, the security posture is adequate for a corporate website but would benefit from enhanced header configurations, documented security policies, and clear incident response channels to improve resilience and trust.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy page and provide clear incident response contact information to facilitate vulnerability reporting and improve transparency.
  3. Consider adding a security.txt file at the root domain to formalize vulnerability disclosure practices.
  4. Verify and update WHOIS domain registration information to ensure transparency and strengthen domain legitimacy.
  5. Enhance contact information visibility on the website by including verified company emails and phone numbers to improve business credibility and user trust.

Technical notes

Notes

The website is built on Syveon CMS 4.2.0 and utilizes modern web technologies such as Google Analytics, Google Tag Manager, and Leadinfo for tracking and analytics. It incorporates Google Fonts and FontAwesome icons for design consistency. The site loads with moderate performance and is optimized for mobile devices, providing a good user experience. SEO practices are well implemented with appropriate meta tags and structured navigation. The use of asynchronous script loading improves page load times. However, the hosting provider is not explicitly identified, and no advanced frameworks or platforms beyond the CMS are detected. The technical infrastructure supports the business needs effectively but could benefit from enhanced security configurations and performance monitoring to reduce technical debt and improve operational stability.
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.
