62/100

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

WeChat is a globally recognized messaging and calling platform operated by Tencent, offering a wide range of communication services including group chat, voice, photo, video, and text messaging. The website targets a broad audience across multiple platforms including iOS, Android, Windows, and Mac, supporting a large user base. The business model focuses on free messaging services with extensions into payment platforms and developer tools, positioning WeChat as a leading player in the technology and telecommunications sector. Technically, the website employs legacy technologies such as jQuery 1.7.2 and provides multiple official app download links. While the site is accessible and well-structured with good mobile optimization, there is room for improvement in modernizing the tech stack and enhancing security headers. The absence of cookie consent mechanisms is a notable gap given GDPR requirements. From a security perspective, the site lacks visible security headers and uses an outdated JavaScript library, which could expose it to vulnerabilities. The WHOIS data is missing or unavailable, which is unusual for a major brand and reduces transparency. However, the presence of comprehensive privacy and terms of service pages, along with official social media links, supports a moderate security posture. Overall, the website is professional and trustworthy but would benefit from technical and security enhancements. Strategic recommendations include updating libraries, implementing security headers, adding cookie consent, and publishing vulnerability disclosure information to strengthen compliance and user trust.

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. 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

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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

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

  • Security headers: did not complete in this scan.
  • 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

WeChat operates as a critical communication platform with a strong market position supported by Tencent. Its competitive advantage lies in its extensive user base and integrated services including payments and platform APIs. Revenue streams likely include payment processing fees and value-added services. The target customers are global mobile and desktop users seeking comprehensive messaging solutions. Growth indicators include continuous platform updates and expansion into payment services. The partnership ecosystem includes Tencent's broader services and payment platforms. Strategic observations highlight the need for enhanced transparency and security practices to maintain leadership in a competitive market.

Security posture

The current security maturity level is moderate with key strengths in privacy policy transparency and platform reach. Identified vulnerabilities include the use of outdated JavaScript libraries and lack of security headers, which could increase risk exposure. Compliance gaps exist in cookie consent and vulnerability disclosure. Data protection practices are partially visible but could be improved with explicit incident response contacts and security certifications. The security culture appears to prioritize user privacy but lacks some modern best practices. Enhancing these areas would reduce risk and improve compliance with regulations such as GDPR.

Recommendations

  1. Update all JavaScript libraries to current secure versions to mitigate known vulnerabilities.
  2. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and HSTS.
  3. Add a cookie consent mechanism to comply with GDPR and other privacy regulations.
  4. Publish a vulnerability disclosure policy and provide clear incident response contact information.
  5. Increase transparency around domain registration and WHOIS data to improve trustworthiness.

Technical notes

Notes

The website uses a legacy jQuery version (1.7.2) which is outdated and may contain security vulnerabilities. The site is structured with standard HTML and CSS, providing good mobile optimization and navigation clarity. Performance is moderate with no explicit hosting provider identified. There is no detected CMS, suggesting a custom or proprietary platform. SEO is adequately addressed with meta tags and keywords. Accessibility is basic but could be improved with ARIA roles and enhanced semantic markup. Modernization opportunities include upgrading the tech stack and improving security configurations.
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.
