Low risk. 1 critical or high finding in Security headers.
Yubico is a recognized industry leader specializing in hardware security keys, notably the YubiKey, which provides strong two-factor authentication solutions for enterprises and individual users. The company positions itself as a trusted provider of phishing-resistant multi-factor authentication, supporting a wide range of platforms and applications. The website reflects a mature digital presence with professional design, SEO optimization, and mobile responsiveness, leveraging WordPress CMS and various marketing and analytics tools such as Google Tag Manager and Visual Website Optimizer. Security-wise, the site enforces HTTPS and promotes a security product that enhances organizational security posture. However, explicit security policies, incident response information, and vulnerability disclosure mechanisms are not evident, which could be improved to enhance trust and compliance. WHOIS data is unavailable from the provided raw output, limiting domain registration trust analysis. Overall, the website demonstrates a strong business and technical foundation with room for improvement in transparency and privacy compliance.
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.

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.
