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

OpenCage GmbH operates a specialized geocoding and geosearch API service that leverages open data sources such as OpenStreetMap to provide worldwide location data conversion. Established in 2013 and headquartered in Berlin, Germany, the company targets developers and enterprises seeking affordable, reliable, and open alternatives to proprietary geocoding services. Their business model includes subscription and pay-as-you-go pricing with a generous free trial, supported by extensive SDKs and tutorials for over 30 programming languages. The website reflects a mature market position with strong trust signals including customer testimonials, corporate memberships, and GDPR compliance. Technically, the website is well-constructed using modern web technologies including Bootstrap and Font Awesome, hosted on Cloudflare infrastructure ensuring fast performance and robust availability. The site is mobile-optimized and accessible, with comprehensive SEO and metadata implementation. Security posture is strong with HTTPS enforced, domain transfer protection, and a dedicated security policy page, although DNSSEC is not enabled and some security headers are not explicitly visible. Privacy compliance is evident with a detailed GDPR policy, but no explicit cookie consent mechanism was detected. Overall, OpenCage demonstrates a high level of digital maturity and business credibility. The security posture is solid with room for minor improvements in DNS security and vulnerability disclosure transparency. The website content is professional, safe, and highly relevant to its target audience. No blocking or WAF challenges were detected, allowing full content analysis. Strategic recommendations include enabling DNSSEC, publishing a security.txt file for vulnerability reporting, implementing a cookie consent mechanism if cookies are used, and enhancing security headers to further harden the site against common web threats.

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 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

OpenCage GmbH is positioned as a niche technology provider in the geospatial data services market, focusing on open data and affordability. Their competitive advantage lies in aggregating multiple open geocoders behind a single API with permissive licensing and no vendor lock-in. The company serves a diverse customer base including logistics, micromobility, academia, classifieds, and IoT sectors. Revenue streams are primarily from API subscriptions and enterprise contracts. The presence of numerous customer logos and testimonials indicates healthy market adoption and customer satisfaction. The company maintains a strong community and open-source ethos, being a corporate member of the OpenStreetMap Foundation and other geoinformatics associations. Their strategic focus on transparency, predictable pricing, and open data aligns well with current market trends favoring open-source and cost-effective solutions.

Security posture

OpenCage exhibits a mature security posture with mandatory HTTPS enforced across all API requests and website traffic, ensuring data confidentiality and integrity. The domain is protected against unauthorized transfers via clientTransferProhibited status, and the company maintains GDPR compliance with a comprehensive privacy policy. However, DNSSEC is not enabled, which could expose DNS queries to spoofing or cache poisoning attacks. The absence of a published security.txt file or explicit vulnerability disclosure policy may limit coordinated vulnerability reporting. Security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not explicitly detected, representing an opportunity to enhance defense-in-depth. No exposed sensitive data or vulnerable libraries were identified. Overall, the security posture is strong but could benefit from incremental improvements to DNS security and transparency in vulnerability management.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS integrity and prevent spoofing.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  3. Implement and explicitly declare security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Add a cookie consent mechanism if cookies are used to enhance GDPR compliance and user privacy.
  5. Maintain and publicize incident response contact channels to improve security communication and trust.

Technical notes

Notes

The website is built on a modern, responsive front-end framework (Bootstrap) with extensive use of JavaScript and CSS for UI/UX enhancements. It leverages Cloudflare for DNS and hosting, ensuring high availability and performance. The presence of multiple SDKs and tutorials for over 30 programming languages indicates a strong developer focus and ecosystem support. The site is well-optimized for SEO with comprehensive meta tags including Open Graph and Twitter cards. Performance is fast with prefetching of fonts and assets. Accessibility is good with semantic HTML and ARIA labels. No CMS was detected, suggesting a custom or static site architecture. The technical stack is robust with low technical debt and good modernization, supporting scalable API services.
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.
