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

4 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

      • 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';…

  2. GDPR outside view

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

    • 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

  3. 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

TSYS operates in the finance and technology sectors, focusing on payment processing and issuer solutions. Their business model centers on providing cloud-native, configurable payment platforms to a diverse client base including banks, fintechs, and retailers. The company benefits from its position as a subsidiary of Global Payments, enhancing its market reach and credibility. TSYS emphasizes innovation, scalability, and customer-centric solutions, which are evident in their product offerings and website content. The partnership ecosystem includes developer portals and career sites linked to the parent company, supporting growth and talent acquisition. The website's content and structure indicate a strategic focus on digital transformation and customer engagement, positioning TSYS as a forward-looking leader in payment technologies.

Security posture

The website demonstrates a moderate to strong security posture with HTTPS enforced and the implementation of a cookie consent mechanism via OneTrust, supporting GDPR compliance. However, the absence of visible security headers, published security policies, incident response contacts, and vulnerability disclosure mechanisms suggests areas for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of reputable analytics and marketing tools is balanced with privacy considerations. Overall, the security maturity is adequate for an enterprise website but could be enhanced by greater transparency and formal security documentation.

Recommendations

  1. Implement and publish comprehensive security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to strengthen site security.
  2. Publish a dedicated security policy page and provide clear incident response contact information to improve transparency and trust.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Enhance privacy compliance by linking to a detailed privacy policy and cookie policy pages with clear GDPR adherence statements.
  5. Regularly audit third-party scripts and analytics tools to minimize privacy risks and ensure compliance with data protection regulations.

Technical notes

Notes

The website is built on a modern technology stack featuring a cloud-native, microservices-based platform. It uses Sitecore CMS for content management, integrates advanced analytics tools such as Microsoft Clarity, Google Tag Manager, and Visual Website Optimizer, and employs OneTrust for cookie consent management. The site is mobile-optimized with responsive design and accessibility features. Performance is moderate, with multimedia content and video elements enhancing user engagement. Technical risks are minimal, though the absence of some security headers and explicit hosting provider information suggests opportunities for infrastructure hardening and transparency improvements.
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.
