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

SENSIC is a service platform operated by GfK SE, a well-established German market research company founded in 2007. The website serves as a help center providing implementation guides for stream measurement and site tracking services, targeting business clients requiring data measurement and tracking solutions. The platform is supported by recognized certifications such as Google Ads, IAB, and AMP, reinforcing its credibility in the advertising and technology sectors. Technically, the website is hosted on Amazon Web Services and utilizes MaxMind GeoLite2 data for geolocation services. The site demonstrates moderate performance and basic mobile optimization, with a clean and professional design. However, it lacks advanced security headers and cookie consent mechanisms, which are important for compliance and security best practices. From a security perspective, the domain is well-registered with a long history and appropriate domain status flags to prevent unauthorized changes. No WAF or blocking mechanisms are detected, and no vulnerabilities are apparent from the provided data. Privacy compliance is partial, with a privacy policy present but no cookie policy or GDPR consent mechanisms visible. Contact information is clearly provided, enhancing trustworthiness. Overall, the website presents a professional and trustworthy front for GfK SE's SENSIC services but would benefit from enhanced security headers, cookie consent implementation, and clearer privacy compliance measures to improve its security posture and regulatory adherence.

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

8 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

  3. 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

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.

Breach exposure

Leaked credentials and lookalike domains from OffSeq Breach. The counts are free; the detailed lists are paid add-ons.

Dark web exposure

Add-on

Leaked records that mention sensic.net, from OffSeq Breach.

No leaked records found

Breach holds no records for sensic.net right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context

Business profile

GfK SE operates SENSIC as a B2B service offering focused on data measurement and site tracking, positioning itself as a technology provider within the market research and advertising ecosystem. The company leverages partnerships and certifications with major industry bodies to maintain competitive advantage and trust. Its business model centers on providing technical solutions to clients requiring detailed measurement of video, audio streams, and site traffic. The target audience includes advertisers, media companies, and market researchers. The company’s long domain age and consistent branding indicate stability and maturity in the market. The absence of social media links and limited public-facing content suggests a focus on controlled client access and professional service delivery.

Security posture

The security posture of the website is moderate. The domain registration is stable and secure with prohibitive domain status flags. However, the website lacks visible security headers such as Content-Security-Policy and Strict-Transport-Security, which are critical for mitigating common web vulnerabilities. There is no evidence of a published security policy or incident response contacts, which limits transparency and readiness for security incidents. The absence of cookie consent mechanisms and terms of service indicates partial compliance with privacy regulations like GDPR. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the site would benefit from implementing standard security best practices and enhancing privacy compliance to reduce risk.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Implement and publish a comprehensive security policy and incident response contact information.
  3. Add a cookie policy and consent mechanism to comply with GDPR and other privacy regulations.
  4. Deploy security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve web security.
  5. Improve mobile optimization and accessibility to enhance user experience and compliance.

Technical notes

Notes

The website is hosted on Amazon Web Services and uses MaxMind GeoLite2 data for geolocation, indicating a modern and scalable infrastructure. The HTML content is well-structured with professional styling and branding consistent with GfK SE. However, there is no evidence of a CMS or advanced frameworks in use, suggesting a possibly custom or static site. Performance is moderate with basic mobile optimization and accessibility features. SEO optimization is basic, with minimal meta tags and no structured data beyond the WHOIS information. The site relies on external links for forms and additional resources, reducing direct data collection risks but also limiting user engagement on the site itself. Technical risks include lack of DNSSEC and missing security headers, which should be addressed to improve resilience.
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.
