Efilli is a Turkish technology company specializing in consent management platforms that ensure compliance with data privacy regulations such as KVKK, GDPR, and LGPD. Positioned as Turkey’s leading consent management provider, Efilli serves over 450 customers and manages consents for more than 2,000 domains. Their key services include website and mobile app consent management, cookie scanning, legal text management, and consent analytics. The company emphasizes ease of compliance and trust-building with end users through automated and customizable consent solutions. Technically, the website is built on Webflow CMS, leveraging modern web technologies including Google Tag Manager and Wistia for analytics and media. The site is hosted with Cloudflare DNS and uses HTTPS with a good SSL configuration. The design is professional, mobile-optimized, and accessible, reflecting a mature digital presence. Integration with Google Consent Mode v2 and ISO 27001 certification further demonstrate technical and compliance maturity. From a security perspective, Efilli enforces HTTPS, maintains domain transfer protections, and holds ISO 27001 certification, indicating a strong security posture. However, DNSSEC is not enabled and security headers are not explicitly detected, suggesting areas for improvement. No critical vulnerabilities or exposed sensitive data were found. Privacy compliance is well addressed with clear privacy and cookie policies, consent mechanisms, and GDPR alignment. Overall, Efilli presents a low-risk profile with a strong business credibility and technical foundation. The website is trustworthy, professionally maintained, and focused on delivering compliant consent management solutions. Strategic recommendations include enabling DNSSEC, implementing security headers, and publishing a vulnerability disclosure policy to enhance transparency 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

3 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

  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 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

Efilli operates in the technology sector, providing SaaS solutions for data privacy compliance primarily targeting businesses in Turkey and the EU. Their competitive advantage lies in comprehensive consent management that covers websites and mobile apps, backed by integrations with global standards like Google Consent Mode and IAB TCF 2.2. Revenue streams likely include subscription plans as indicated by the pricing form. The company has established partnerships and presence in privacy-focused events and networks, enhancing market credibility. Growth indicators include a large volume of monthly consents (88.5 million) and a broad client base including major corporations. The business model is B2B SaaS with a focus on regulatory compliance and trust-building.

Security posture

Efilli demonstrates a mature security posture with ISO 27001 certification and HTTPS enforcement. The domain is protected with clientTransferProhibited status, reducing hijacking risk. No exposed credentials or vulnerabilities were detected in the website content. However, the absence of DNSSEC and security headers such as CSP, HSTS, and X-Frame-Options indicates room for improvement. Incident response contact information and vulnerability disclosure mechanisms are not publicly available, which could be enhanced to improve transparency and readiness. Overall, the security maturity is good but could be elevated by adopting additional best practices and publishing security policies.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-Content-Type-Options.
  3. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Provide explicit incident response contact channels such as security@ or abuse@ email addresses.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.

Notes

Opportunities exist to enhance security configurations and further optimize performance through security headers and DNSSEC.
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.
