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.

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

Krystal operates in the technology sector with a focus on sustainable web hosting. Its business model centers on providing premium hosting services with a strong ethical and environmental commitment, reinvesting profits into planet protection rather than shareholder returns. The company targets UK businesses and individuals valuing performance, security, and sustainability. With over 37,000 active customers and more than 270,000 websites hosted, Krystal has established a solid market presence. Partnerships with organizations like USEO and integration with platforms such as Sirportly enhance its service ecosystem. The company maintains a moderate size and a consistent brand image, supported by high customer satisfaction and trust indicators.

Security posture

Krystal demonstrates a moderate security maturity level with ISO 27001 certification and robust DDoS protection claims. Email security is supported by SPF and DMARC records with abuse reporting channels. However, the absence of a valid SSL certificate and HTTPS on the main domain is a critical vulnerability, severely impacting the security posture. Additionally, the lack of modern TLS protocols, HSTS, OCSP stapling, session resumption, and security headers exposes the site to potential risks and undermines user trust. While no active vulnerabilities or malware were detected, these configuration gaps should be addressed promptly to align with best practices and compliance requirements.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across the website.
  2. Enable modern TLS protocols (TLS 1.2 and 1.3) and disable outdated versions.
  3. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  4. Enable OCSP stapling to improve certificate revocation checking performance and security.
  5. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  6. Regularly audit and update security configurations to maintain compliance with GDPR and industry standards.
  7. Enhance transparency by publishing a vulnerability disclosure policy or security.txt file.
  8. Maintain and promote incident response contacts and procedures for timely handling of security events.
  9. Continue investing in customer support and sustainability initiatives to strengthen market differentiation.
  10. Monitor and optimize website performance to improve user experience and SEO rankings.

Technical notes

Notes

The website is built using modern web technologies including Next.js and React, leveraging server-side rendering and optimized image loading. The tech stack includes LiteSpeed caching and cPanel for hosting management. The site is mobile-optimized with good accessibility and SEO practices, including comprehensive meta tags and structured data (JSON-LD). Hosting is provided on Krystal's own infrastructure and their Katapult public cloud platform. Performance is moderate with a page load time of approximately 7.9 seconds and a large page size (~955 KB). There is room for improvement in SSL/TLS configuration and security headers to reduce technical risks and enhance trust.
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.
