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

Katalyze Data is a UK-based data consultancy specializing in advanced analytics, data science, and tailored data solutions to accelerate business growth. Founded in 2022, the company leverages over 30 years of combined experience, having completed more than 1,500 projects for over 500 customers. Their key services include advisory, design and deployment of analytics platforms, maintenance and improvement of data solutions, and training in SAS, R, and Python. The company positions itself as a trusted partner for businesses seeking to unlock the power of their data through modern analytics technologies and cloud solutions. Technically, the website is built on WordPress 7.0 with a modern tech stack including Yoast SEO, Google Tag Manager, Hotjar, and LinkedIn Insight Tag, indicating a mature digital presence. The site is mobile-optimized, SEO-friendly, and integrates multiple marketing and analytics tools with a compliant cookie consent mechanism. Hosting appears to be via GoDaddy, consistent with the domain registrar information. From a security perspective, the site enforces HTTPS and employs domain registration locks to prevent unauthorized changes. The presence of Cyber Essentials Plus certification is a strong trust indicator. However, DNSSEC is not enabled, and no explicit security policy or incident response contacts are published, representing areas for improvement. The site uses multiple third-party scripts which should be regularly audited to mitigate supply chain risks. Overall, the website is professional, trustworthy, and compliant with privacy regulations such as GDPR. The domain registration details align well with the business claims, supporting legitimacy. Strategic recommendations include enabling DNSSEC, publishing security and incident response policies, and enhancing security headers to further strengthen the security posture.

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

6 findings rated critical or high. Fix these first.

  1. 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

Katalyze Data operates in the technology sector as a specialized consultancy focused on analytics and data science. Their business model combines consultancy services with training and product offerings such as SAS, Posit, and Statilyze. The company targets medium to large enterprises seeking to modernize and optimize their data analytics capabilities. Their market position is supported by a strong project portfolio and certifications like Cyber Essentials Plus. The company maintains active engagement through social media and content marketing via insights and webinars. The use of advanced marketing and analytics tools indicates a data-driven approach to customer acquisition and retention. No parent or subsidiary companies were identified, suggesting an independent operation. The company’s growth potential is supported by its comprehensive service offerings and technical expertise.

Security posture

The security posture of Katalyze Data’s website is solid but with room for enhancement. HTTPS is properly implemented, and domain registration includes protective status flags to prevent unauthorized transfers or deletions. The Cyber Essentials Plus certification displayed is a positive indicator of organizational security practices. The site uses a cookie consent banner compliant with GDPR, and no sensitive data exposure was detected in the HTML content. However, DNSSEC is not enabled, which could improve DNS security. No security.txt or explicit incident response contact information is published, which is a gap in transparency and readiness. The site relies on multiple third-party scripts for analytics and marketing, which necessitates ongoing security monitoring. Security headers were not detected in the provided data, suggesting an opportunity to implement headers like Content-Security-Policy and X-Frame-Options to mitigate common web attacks. Overall, the security score is good but could be improved with these measures.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Regularly audit and update third-party scripts to mitigate supply chain vulnerabilities.
  5. Maintain and promote security certifications and trust indicators to enhance customer confidence.

Technical notes

Notes

The website is built on a modern WordPress CMS platform with version 7.0, utilizing popular plugins such as Yoast SEO for search engine optimization and Beautiful and Responsive Cookie Consent for privacy compliance. The tech stack includes jQuery 3.7.1, Google Tag Manager, Google Analytics, Hotjar, LinkedIn Insight Tag, and Calendly for scheduling, indicating a mature and integrated digital infrastructure. Hosting is inferred to be with GoDaddy based on registrar and nameservers. The site demonstrates good mobile optimization and accessibility features. Performance is moderate, with potential improvements possible through optimization of third-party scripts and caching. The site uses structured data (JSON-LD) for SEO and social media integration. Overall, the technical implementation supports a professional and user-friendly experience but could benefit from enhanced security configurations and performance tuning.
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.
