Risk levelLow

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

ChangeGroup is a well-established global leader in currency exchange and related financial services, operating over 100 bureaus across multiple continents. Owned by Prosegur, a publicly listed company, ChangeGroup offers a broad portfolio including currency exchange, money transfers, tax free refunds, and ATM networks, targeting international travelers and business clients. The website reflects a mature digital presence with a focus on user experience and accessibility. Technically, the site uses modern web technologies and appears to be built on a robust CMS platform, likely Adobe Experience Manager. Security posture is strong with HTTPS enforced and cookie consent implemented, though explicit security headers and policies could be improved. WHOIS data for the subdomain is unavailable, which is expected and not suspicious. Overall, the site demonstrates professionalism, trustworthiness, and compliance with privacy regulations.

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

1 finding rated critical or high. Fix these first.

  1. 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

ChangeGroup holds a strong market position as a currency exchange leader with a diversified service offering and a global footprint. Its parent company, Prosegur, adds credibility and scale. The business model combines physical branch services with online ordering and partnerships for international money transfers, such as with Convera. The company targets international travelers and businesses requiring currency and payment services. The website supports this with clear service descriptions, branch locators, and corporate information. The partnership ecosystem includes Convera and multiple country-specific ChangeGroup sites, indicating a broad operational network. Growth indicators include ongoing expansion plans and technology investments in ATM and payment systems.

Security posture

The website demonstrates a solid security foundation with HTTPS and cookie consent mechanisms in place. No exposed sensitive data or vulnerable libraries were detected. However, the absence of explicit security headers (e.g., CSP, HSTS) and lack of published security policies or incident response contacts represent areas for improvement. There is no evidence of a vulnerability disclosure program or security.txt file. Privacy compliance is well addressed with GDPR-aligned policies and cookie management. Incident response readiness and security culture indicators are not publicly visible, which could be enhanced to build further trust.

Recommendations

  1. Implement and publish comprehensive security headers such as Content Security Policy, HSTS, and X-Frame-Options to strengthen defense against common web attacks.
  2. Create and publish a dedicated security policy and incident response page including contact channels for security issues to improve transparency and readiness.
  3. Develop a vulnerability disclosure program and add a security.txt file to encourage responsible reporting of security issues.
  4. Enhance website accessibility features to meet higher standards and improve user experience for all visitors.
  5. Add a clear terms of service page to complement privacy and cookie policies, ensuring full legal compliance and user clarity.

Technical notes

Notes

The website is built on a modern technology stack including JavaScript, Google Fonts, FontAwesome, and AOS for animations, likely integrated within a proprietary or customized framework named ProsegurWebCorpModule. The CMS appears to be Adobe Experience Manager or a similar enterprise-grade platform, indicated by JCR and DAM references. The site is mobile optimized with responsive design and good SEO practices including meta tags and structured data. Performance is moderate with some preloading optimizations. There is no explicit hosting provider identified. Technical risks are low, but opportunities exist to improve security headers and accessibility compliance.
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.
