badssl.com is a specialized educational and testing website designed to demonstrate and test various HTTPS and SSL/TLS misconfigurations. It serves developers, security professionals, and testers by providing a wide range of subdomains that simulate different certificate and protocol issues. The site is positioned as a niche resource in the technology sector, focusing on security education and testing rather than commercial services. Technically, the site uses standard web technologies such as HTML5, CSS3, and JavaScript without reliance on major CMS or frameworks, resulting in fast performance and good mobile optimization. Security-wise, the site enforces HTTPS and provides multiple test cases for SSL/TLS configurations, though it lacks explicit security headers and formal security policies. Privacy compliance is minimal, with no visible privacy or cookie policies, and no contact or business information is provided. Overall, the site is trustworthy and safe, with a strong focus on security education but limited business transparency or compliance documentation.
Scanned
NIS2 Art. 21(2)
The NIS2 figure counts only evidence anyone can see from the internet. 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.
2 findings rated critical or high. Fix these first.
SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.
badssl.com publishes no SPF record, so receiving servers cannot tell which servers may send mail as this domain.
What to do: Publish one TXT record listing your mail providers, for example "v=spf1 include:_spf.yourprovider.com -all". A domain that sends no mail should publish "v=spf1 -all".
There is no DMARC record at _dmarc.badssl.com, so receivers have no instruction for mail that fails SPF and DKIM.
What to do: Publish a TXT record at _dmarc.badssl.com, starting with "v=DMARC1; p=none; rua=mailto:dmarc@badssl.com" and moving to p=quarantine or p=reject once reports look clean.

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.

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.
