0–100, higher is better. How it is calculated

Krystal Hosting Ltd is a UK-based independent web hosting company specializing in ethical and sustainable hosting solutions powered by 100% renewable energy. Established in 2002, it offers a broad range of services including web hosting, business hosting, managed WordPress, VPS, dedicated servers, and public cloud services. The company positions itself as a trusted green hosting provider with strong customer support and multiple certifications such as ISO 27001 and B Corp status. Technically, the website is built on modern frameworks like Next.js and React, delivering a good user experience with mobile optimization and SEO best practices. However, the current SSL certificate is invalid and no TLS protocols are enabled, which significantly impacts the security posture. Despite this, the company maintains strong security practices including DDoS protection, real-time malware scanning, and daily backups. The domain registration is consistent with the business identity, showing a mature and legitimate presence. Overall, Krystal Hosting presents a professional, trustworthy, and customer-focused hosting provider with room for improvement in SSL/TLS configuration to enhance security.

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.

Business context

Business profile

Krystal Hosting operates in the technology sector with a focus on sustainable and ethical web hosting. Its business model centers on providing premium hosting services with an emphasis on environmental responsibility and customer satisfaction. The company targets UK businesses and individuals who value green hosting and reliable support. With over 37,000 active customers and more than 270,000 websites hosted, Krystal has a significant market presence. Its partnerships with platforms like Katapult and certifications from B Corp and 1% for the Planet enhance its competitive advantage. The company reinvests profits into sustainability initiatives, planting trees monthly for active clients. The transparent display of statistics and customer testimonials supports its market credibility and growth potential.

Security posture

Krystal Hosting demonstrates a mature security posture with ISO 27001 certification and robust infrastructure protections including 4,000Gbps DDoS mitigation and real-time malware scanning. The presence of HSTS with includeSubDomains is a positive security control. However, the invalid SSL certificate and absence of enabled TLS protocols represent critical vulnerabilities that could expose users to interception and trust issues. The lack of OCSP stapling and session resumption further reduces security and performance. No explicit incident response or vulnerability disclosure policies were found, indicating potential gaps in transparency and readiness. Overall, while foundational security practices are strong, immediate remediation of SSL/TLS issues is essential to maintain trust and compliance.

Recommendations

  1. Immediately renew and correctly configure SSL certificates to ensure HTTPS security.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable deprecated ones.
  3. Implement OCSP stapling and session resumption to improve security and performance.
  4. Correct malformed CAA DNS records to prevent certificate issuance issues.
  5. Publish clear incident response and vulnerability disclosure policies to enhance transparency.

Technical notes

Notes

The website leverages a modern technology stack including Next.js and React, providing a responsive and accessible user experience optimized for mobile devices. Hosting is managed on Krystal's own infrastructure with additional cloud options via Katapult, AWS, and Azure. Performance is moderate with a page load time of approximately 8 seconds and a large page size (~956 KB), suggesting opportunities for optimization. SEO is well addressed with comprehensive meta tags and Open Graph data. Accessibility features such as skip links and semantic HTML are present. The site uses Google Tag Manager for analytics and marketing, with a cookie consent mechanism in place. Technical debt is minimal but SSL/TLS misconfiguration poses a risk to operational security and user 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.
