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.

Priority findings

3 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 Hosting Ltd operates in the technology sector, focusing on web hosting and cloud services with a unique selling proposition centered on sustainability and green energy. Their business model is subscription-based, targeting businesses and individuals who value performance, security, and environmental responsibility. The company has established a solid market position in the UK with over 39,000 active customers and more than 278,000 websites hosted. Their partnership ecosystem includes their own Katapult cloud platform and third-party integrations like Sirportly for customer support. Growth indicators include a large number of domains managed and a commitment to planting over 4.8 million trees. The company leverages certifications and awards to differentiate itself and build trust. Their strategic focus on managed services and tailored solutions indicates a move towards higher-value offerings and customer retention.

Security posture

Krystal Hosting Ltd exhibits a strong security maturity level, evidenced by ISO 27001 certification and comprehensive protective measures such as 4,000Gbps DDoS protection, free SSL certificates, real-time malware scanning, and frequent backups. The website enforces HTTPS and implements multiple security headers, enhancing protection against common web threats. No exposed sensitive data or vulnerable libraries were detected. However, the absence of publicly available incident response and vulnerability disclosure policies represents a compliance gap and an opportunity for improvement. The company’s security culture is reinforced by transparent communication of certifications and trust signals, but formalizing incident response channels would enhance readiness and client confidence. Overall, the security posture is robust with minor areas for enhancement.

Recommendations

  1. Publish a clear incident response policy and contact channels to improve transparency and readiness.
  2. Implement and publicize a vulnerability disclosure policy and security.txt file to facilitate responsible reporting.
  3. Consider appointing and publishing Data Protection Officer contact information to strengthen GDPR compliance.
  4. Maintain and regularly update security headers and SSL configurations to uphold high security standards.
  5. Enhance advertising transparency by clearly disclosing tracking and marketing practices to users.

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.
