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

NESİL BİLİŞİM TEKNOLOJİLERİ TİC. A.Ş. operates as a prominent Turkish technology company specializing in cybersecurity, data protection, and regulatory compliance services such as KVKK consultancy, penetration testing, and information security management. The company targets corporate clients in regulated sectors including banking, telecommunications, healthcare, and payment systems, positioning itself as a trusted partner with certifications like ISO 27001 and accreditations from TSE and Türkak. Their service portfolio includes software code analysis, AI solutions, and privacy management platforms, reflecting a comprehensive approach to modern cybersecurity challenges. Technically, the website is built on WordPress with modern plugins and frameworks, incorporating SEO best practices, accessibility features, and integration with Google Analytics and Tag Manager. The site demonstrates good mobile optimization and user experience, with clear navigation and professional design. Security measures include HTTPS enforcement and use of reCAPTCHA, though some security headers are not explicitly detected and could be improved. From a security posture perspective, the company shows maturity with published security policies and certifications, but lacks visible incident response or vulnerability disclosure mechanisms. The absence of WHOIS registration data for the domain is a notable anomaly that reduces trust and should be investigated further to confirm domain ownership and legitimacy. Overall, NESİL Teknoloji presents a professional and credible digital presence with strong compliance and security focus, serving a critical niche in the Turkish market. Addressing WHOIS transparency and enhancing security headers would further strengthen their trustworthiness and security posture.

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

7 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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • 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

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.

Business context

Business profile

NESİL Teknoloji holds a strong market position in Turkey's cybersecurity and data protection sector, leveraging regulatory compliance requirements such as KVKK, BDDK, SPK, and GDPR to drive demand for its consulting and technical services. Their business model centers on providing tailored security solutions and compliance assistance to regulated industries, supported by recognized certifications and a portfolio of successful client projects including major banks and industrial firms. The company’s growth is supported by a diversified service offering that includes penetration testing, AI-driven solutions, and privacy management platforms, enabling cross-selling opportunities and long-term client relationships. Their active social media presence and published success stories enhance brand visibility and credibility. Strategic partnerships with regulatory bodies and adherence to international standards position NESİL Teknoloji as a trusted advisor in the cybersecurity ecosystem.

Security posture

The website and company demonstrate a solid security posture with HTTPS enforced, use of reCAPTCHA on forms, and published information security policies aligned with ISO 27001 and related standards. The presence of penetration testing services and code analysis indicates proactive vulnerability management. However, the lack of explicit security headers such as Content-Security-Policy and X-Frame-Options is a gap that could expose the site to certain web-based attacks. No incident response or vulnerability disclosure policies are publicly available, which limits transparency and readiness perception. The missing WHOIS data for the domain raises concerns about domain ownership verification, which is critical for trust in cybersecurity services. Overall, the security posture is good but could be improved by enhancing HTTP headers, publishing incident response plans, and clarifying domain registration details.

Recommendations

  1. Verify and update WHOIS domain registration information to ensure transparency and trust.
  2. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a formal incident response and vulnerability disclosure policy to improve transparency and client confidence.
  4. Regularly update WordPress core and plugins to mitigate risks from outdated software.
  5. Enhance contact information visibility by adding verified company emails and phone numbers for direct communication.

Technical notes

Notes

The website is built on a modern WordPress platform using popular plugins such as WPBakery Page Builder and Ultimate VC Addons, ensuring flexible content management and responsive design. Integration with Google Tag Manager and Analytics via Site Kit indicates a mature approach to performance monitoring and marketing analytics. The site loads with moderate speed and is optimized for mobile devices with good accessibility features including skip links and ARIA attributes. The use of Algolia search and reCAPTCHA enhances user experience and security. However, the hosting provider is not explicitly identified, and some security headers are missing, which could be addressed to reduce technical risks. Overall, the technical infrastructure supports the business needs effectively but has room for security hardening and performance tuning.
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.
