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

  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
    • 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

  • Network security: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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 company targets industrial clients primarily in manufacturing and automotive sectors, offering custom cable and electromechanical solutions. Their business model combines manufacturing with component distribution, supported by a parent investment group CEIP. The website content and certifications indicate a mature business with a medium-sized workforce and a broad product portfolio. Partnerships with industry associations and local sponsorships enhance their market credibility. The company demonstrates growth and modernization through digital tools and e-commerce integration.

Security posture

KOSYKA's website shows a moderate to good security maturity level. HTTPS is enforced, and cookie consent is implemented with granular user controls, supporting GDPR compliance. However, the absence of visible security headers such as CSP or HSTS and lack of a public incident response or vulnerability disclosure policy indicate areas for improvement. No exposed sensitive data or vulnerable libraries were detected. The use of third-party tracking and retargeting services is transparent and controlled via consent. Overall, the security posture is adequate but could be enhanced with additional best practices.

Recommendations

  1. Implement comprehensive HTTP security headers including Content Security Policy (CSP), HSTS, and X-Frame-Options.
  2. Publish a dedicated security policy page including incident response and vulnerability disclosure information.
  3. Conduct regular security audits of third-party scripts and tracking tools to ensure privacy compliance.
  4. Enhance website accessibility features to meet WCAG standards for broader compliance.
  5. Establish and communicate data retention policies for collected analytics and user data.

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.
