Risk levelMedium

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

Nesil Grup Teknoloji Tic. A.Ş operates the Cerezgo platform, a cookie consent management solution designed to help websites comply with Turkish KVKK and GDPR regulations. The company has over 15 years of experience in technology and data protection consultancy, serving a broad range of sectors in Turkey. Their website reflects a professional and trustworthy business with clear service offerings and certifications such as ISO 27001. Technically, the site uses modern web technologies including Bootstrap and jQuery, and integrates multiple analytics and marketing tools. Security posture is solid with HTTPS and domain transfer protections, though improvements like DNSSEC and security headers are recommended. Privacy compliance is partially addressed with a detailed cookie policy and consent mechanism, but lacks a dedicated privacy policy and terms of service pages. Overall, the website and business demonstrate a mature digital presence with room for enhanced security and compliance documentation.

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

5 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Twitter, LinkedIn, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  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

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

The company positions itself as a trusted technology and consultancy provider specializing in personal data protection and cookie consent management. Their business model targets other businesses requiring compliance solutions, leveraging certifications and a broad client base as competitive advantages. The partnership with Nesil Teknoloji strengthens their market presence. Revenue likely derives from subscription plans for cookie management services and consultancy fees. The website's client references and certifications indicate a stable and reputable operation with growth potential in the Turkish and regional markets.

Security posture

The security maturity level is moderate to good. The use of HTTPS and clientTransferProhibited domain status are positive indicators. However, the absence of DNSSEC and security headers such as CSP and HSTS reduces the overall security posture. No incident response or abuse contacts are published, which is a gap in transparency and readiness. The platform's ISO 27001 certification supports a strong internal security framework. No critical vulnerabilities or exposed sensitive data were detected in the website content. Compliance with GDPR and KVKK is supported by the cookie consent platform but lacks full privacy policy documentation.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and publish security headers like Content-Security-Policy, Strict-Transport-Security, and X-Content-Type-Options.
  3. Add a comprehensive privacy policy page detailing GDPR and KVKK compliance measures.
  4. Publish terms of service and incident response contact information to improve transparency and trust.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and improve user trust.

Technical notes

Notes

The website is built on a modern tech stack including Bootstrap 5 and jQuery 3.6.4, with additional libraries for animations and UI components. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. The site is mobile optimized and performs moderately well. SEO and accessibility are basic but functional. The use of multiple analytics and marketing tools indicates a mature digital marketing approach but requires careful privacy management. No CMS was detected, suggesting a custom or proprietary platform. Technical debt appears low, but security enhancements and additional compliance documentation would strengthen the overall infrastructure.
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.
