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

TeamViewer is a leading global provider of remote desktop access and digital workplace solutions, enabling businesses and individuals to connect, support, and collaborate online. The company offers a SaaS model with key services including remote support, remote desktop access, and online collaboration tools. The website targets both enterprise and personal users, emphasizing ease of use and broad accessibility. Technically, the site is built on Adobe Experience Manager, leveraging modern technologies such as Google Tag Manager, reCAPTCHA, Adobe Launch, and OneTrust for cookie consent management. The site is well-optimized for mobile and accessibility, with good SEO practices and fast loading performance. Security-wise, the website enforces HTTPS, uses security headers, and integrates bot protection, but lacks publicly disclosed security policies or incident response information. WHOIS data is unavailable, likely due to privacy protection, which is justified for a large technology company. Overall, the website demonstrates a mature digital presence with strong business credibility and good security posture, though transparency on security policies could be improved.

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. 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.

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

TeamViewer holds a strong market position as a trusted provider of remote connectivity solutions, serving a wide range of customers from individuals to large enterprises. Its business model is subscription-based SaaS, generating revenue through licensing and support services. The company benefits from a global presence with localized content and multiple language support. The website reflects a professional brand with consistent messaging and trust signals such as verified contact information and privacy compliance. The partnership ecosystem includes major technology providers and marketing platforms, enhancing its digital reach. Growth indicators include comprehensive support resources and developer tools, positioning TeamViewer as a versatile platform in the remote access market.

Security posture

The website exhibits a solid security foundation with HTTPS enforcement, modern security headers, and bot mitigation via Google reCAPTCHA. Cookie consent is managed through OneTrust, indicating GDPR compliance. However, the absence of a publicly available security policy, incident response plan, or vulnerability disclosure program limits transparency and may impact stakeholder confidence. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of WHOIS data is mitigated by the professional site presentation and verified contact channels. To enhance security posture, TeamViewer should consider publishing detailed security and incident response information and establishing a formal vulnerability disclosure process.

Recommendations

  1. Publish a dedicated security policy and incident response information on the website.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide contact details for a Data Protection Officer or security team.
  4. Enhance transparency around certifications and compliance frameworks.
  5. Regularly review and update privacy and cookie policies to maintain GDPR 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.
