Medium risk. 7 critical or high findings in Security headers, GDPR outside view and 1 other check.
The website www.51dns.com represents 帝恩思, a Chinese digital security comprehensive service provider established in 2012 and publicly listed (证券代码 837018). The company offers a range of services including DNS resolution, DNS hijacking protection, SSL certificates, website hijacking detection, and downtime monitoring. The site targets enterprises and businesses requiring digital security solutions, positioning itself as a leading player in the Chinese digital security market. Technically, the website employs modern web technologies including HTML5, CSS3, JavaScript, and integrates third-party services such as Baidu Analytics and Tencent Qidian chat for analytics and customer interaction. The site is mobile optimized and demonstrates good SEO practices. However, some accessibility features and security headers are not explicitly detected. From a security perspective, the site uses HTTPS and SSL certificates, but lacks visible security headers and formal privacy or cookie policies. No direct contact information or incident response channels are found, which may impact user trust and compliance. The WHOIS data is unavailable, which raises concerns about domain registration transparency, though the website content and business claims appear professional. Overall, the website is functional and professional but would benefit from enhanced privacy compliance, clearer contact and incident response information, and improved security header implementation to strengthen trust and 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.

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

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.
