Positioned as a leader in the market, recognized by Gartner's Magic Quadrant, Tealium serves a global enterprise audience with a comprehensive suite of products designed to unify, activate, and leverage customer data across multiple touchpoints in real-time. Their offerings include advanced AI data streaming, cloud data activation, and privacy-first healthcare solutions, targeting marketing, IT, and data analytics teams. Technically, the website is built on WordPress with a modern tech stack including Google Analytics, Marketo forms, and Tealium's own tag management scripts. The site demonstrates good SEO, accessibility, and mobile optimization, with a moderate performance profile. Hosting and domain registration are consistent with enterprise standards, leveraging Amazon Registrar and AWS DNS infrastructure. From a security perspective, the site enforces HTTPS and employs cookie consent mechanisms, but lacks explicit security headers and a published security.txt file. No vulnerabilities or exposed sensitive data were detected. Privacy compliance is strong, with clear policies and GDPR adherence. Contact information is transparent, including phone and physical address, enhancing business credibility. Overall, Tealium's website reflects a mature, professional, and trustworthy enterprise with a strong market position in customer data platforms. Strategic recommendations include enhancing security headers, publishing vulnerability disclosure policies, and enabling DNSSEC to further strengthen security posture.
Scanned
NIS2 Art. 21(2)
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.
1 finding rated critical or high. Fix these first.
TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.
Server supports weak protocols: TLSv1.1
What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

Each check with its score, findings and the evidence it collected.
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
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.
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.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
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.
