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

2 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.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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

WNS is a well-established enterprise with a strong global footprint and diversified service offerings across multiple sectors. Its competitive advantage lies in its deep industry knowledge combined with advanced technology and analytics capabilities, including generative AI and hyperautomation. The company leverages partnerships with technology providers like Jiffy.ai and Vuram to enhance its solutions. Revenue streams likely include business process outsourcing, analytics services, technology solutions, and consulting. The target customers are large global enterprises seeking digital transformation and operational excellence. The company’s consistent branding, comprehensive content, and multiple trust signals such as awards and recognitions reinforce its market position and credibility.

Security posture

The security maturity of WNS’s website is good, with enforced HTTPS and use of security tokens in forms to prevent CSRF attacks. The integration of OneTrust for cookie consent indicates compliance with privacy regulations like GDPR. No sensitive data or credentials are exposed in the HTML content. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options suggests room for improvement. There is no visible incident response contact or security.txt file, which could enhance transparency and readiness. Overall, the site follows best practices but could strengthen its security posture by adding missing headers and incident response information.

Recommendations

  1. Implement Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options headers to enhance security.
  2. Publish an incident response contact email or security.txt file to improve transparency and readiness.
  3. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  4. Enhance visibility of security policies and certifications on the website.
  5. Continue to maintain and update privacy and cookie compliance mechanisms in line with evolving regulations.

Technical notes

Notes

The website is built on a mature and widely used CMS platform (DNN) with ASP.NET WebForms, indicating a stable but somewhat legacy technology stack. It employs modern JavaScript libraries such as jQuery, Swiper.js for carousels, and Isotope.js for layout management, providing a rich interactive user experience. The site is mobile-responsive and includes accessibility features, contributing to good usability. Performance is moderate, with some heavy media content like videos and large images. The use of Google Tag Manager and OneTrust reflects a mature approach to analytics and privacy management. Technical risks include potential legacy framework limitations and the need for enhanced security headers. Overall, the technical infrastructure supports the business needs effectively with opportunities for modernization and security enhancements.
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.
