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

WhatsApp LLC operates a globally recognized messaging platform used by over 2 billion users worldwide. The company provides secure, end-to-end encrypted messaging and calling services accessible via mobile apps, desktop clients, and web interfaces. As a subsidiary of Meta Platforms, WhatsApp maintains a strong market position as a leading communication tool for personal and business use. The website content reflects a professional and user-friendly design, emphasizing privacy and security as core values. The technical infrastructure of the website leverages modern web technologies including JavaScript frameworks and optimized CSS, ensuring fast performance and excellent mobile responsiveness. The site is hosted securely with HTTPS and employs robust security headers, indicating a mature digital infrastructure. However, the absence of a visible cookie consent mechanism suggests room for improvement in privacy compliance presentation. From a security perspective, WhatsApp demonstrates strong adherence to best practices, including enforced HTTPS, content security policies, and no visible vulnerabilities or exposed sensitive data. The lack of explicit incident response contacts or a security.txt file is a minor gap in transparency. Overall, the domain and website exhibit high legitimacy and trustworthiness, consistent with a major technology enterprise. Strategically, WhatsApp should enhance its privacy compliance visibility by implementing cookie consent banners and publishing clear security incident response information. These steps will further solidify user trust and regulatory adherence. The website's current state supports a high level of user confidence and operational security.

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

5 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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

  3. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

  4. 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

      SSL Certificate Expires Soon

      SSL certificate expires in 7 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates
    • 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

WhatsApp LLC holds a dominant position in the global messaging market, leveraging its integration with Meta Platforms to offer extensive user reach and business communication solutions. Its business model centers on free messaging and calling services with monetization through business APIs and enterprise tools. The platform targets a broad audience including individual users, small businesses, and large enterprises. Growth indicators include continuous feature expansion such as AI stickers and channels. The company maintains a strong partnership ecosystem with Microsoft for desktop sideloading and social media platforms for brand presence. Operationally, WhatsApp emphasizes privacy and security, which are key competitive advantages in the messaging space.

Security posture

WhatsApp's security posture is robust, featuring industry-standard HTTPS encryption, comprehensive security headers, and end-to-end encryption for user communications. The website does not expose sensitive information or use vulnerable libraries, reflecting a mature security culture. Compliance with GDPR is indicated through privacy policies, though cookie consent mechanisms are not explicitly visible. The absence of a published incident response contact or vulnerability disclosure page suggests an opportunity to improve transparency and responsiveness. Overall, WhatsApp demonstrates a high security maturity level appropriate for its scale and user base, with minor areas for enhancement in compliance communication.

Recommendations

  1. Implement a visible cookie consent banner to enhance GDPR compliance and user transparency.
  2. Publish explicit incident response and security contact information to improve vulnerability management and trust.
  3. Create and maintain a security.txt file to facilitate responsible vulnerability disclosure.
  4. Enhance contact information availability on the website to support user and business inquiries.
  5. Continue regular security audits and updates to maintain strong security posture and address emerging threats.

Technical notes

Notes

The website employs a modern and efficient technical stack with asynchronous JavaScript loading, modular CSS, and optimized resource delivery from static.whatsapp.net. The use of Facebook's internal frameworks such as Haste and Bootloader indicates a sophisticated infrastructure. Performance is fast with good mobile optimization and accessibility features. SEO is supported by comprehensive meta tags and Open Graph data. No CMS is detected, suggesting a custom-built platform. Hosting details are not explicitly disclosed but likely leverage Meta's global infrastructure. Technical risks are minimal, with opportunities to improve privacy compliance presentation and incident response transparency.
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.
