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

CSIS is a cybersecurity services provider specializing in actionable, intelligence-driven detection and response services. The company offers a broad portfolio including managed detection and response, SOC escalation, SIEM and XDR acceleration, digital risk protection, consulting, emergency response, and cyber threat intelligence. The website positions CSIS as a leader in the cybersecurity industry with recognized certifications such as CREST accreditation, targeting enterprise clients seeking advanced security solutions. Technically, the website is built on HubSpot CMS, leveraging Cloudflare for hosting and security, and implements a comprehensive cookie consent mechanism compliant with GDPR. The security posture is strong with HTTPS and Cloudflare protection, though explicit security headers and a public security policy are absent. WHOIS data for the domain is missing, which raises some concerns about domain registration transparency. Overall, the website is professional, well-structured, and trustworthy, but would benefit from enhanced transparency on domain registration and security policies.

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 · found on this site
  • 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

CSIS operates in the technology sector focusing on cybersecurity services. Its market position is strong, supported by CREST accreditation and a comprehensive service offering. The business model revolves around managed security services, consulting, and digital risk protection, targeting medium to large enterprises. The company uses HubSpot for marketing and content management, indicating a mature digital marketing strategy. Partnerships with Cookie Information and Avidly Agency enhance its marketing and compliance capabilities. The absence of explicit contact emails and phone numbers suggests a preference for contact via web forms, which is common in enterprise B2B models. The website content and navigation are professional and consistent, supporting a high level of business credibility.

Security posture

The website enforces HTTPS and uses Cloudflare, providing robust protection against common web threats and DDoS attacks. The presence of a detailed cookie consent banner indicates compliance with privacy regulations. However, no explicit security headers (such as CSP, HSTS, or X-Frame-Options) were detected, which could improve security posture. There is no visible security policy or incident response contact information, which are best practices for transparency and trust. The lack of WHOIS data for the domain is a potential red flag, though the website's professional appearance and certifications mitigate some concerns. Overall, the security posture is good but could be enhanced with additional headers and published policies.

Recommendations

  1. Implement and publish explicit security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and trust with clients and visitors.
  3. Investigate and resolve the missing WHOIS domain registration data to ensure domain registration transparency and improve legitimacy perception.
  4. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Consider adding explicit contact emails and phone numbers for sales and support to improve accessibility and business credibility.

Technical notes

Notes

The website is built on the HubSpot CMS platform, utilizing Cloudflare for CDN and security services. It uses modern web technologies including HTML5, CSS, and JavaScript. The site is mobile optimized and accessible with a clear navigation structure. Cookie consent is managed via Cookie Information, ensuring GDPR compliance. Performance is moderate, likely influenced by the use of multiple external scripts and tracking services. No critical technical issues or vulnerabilities were detected in the provided content. Opportunities exist to improve security headers and domain registration transparency to reduce technical risks.
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.
