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

Colt Technology Services is a mature, enterprise-level global digital infrastructure company specializing in managed network and voice services. The company offers a comprehensive portfolio including Network as a Service, cloud connectivity, cybersecurity, capital markets connectivity, and professional services. With a strong presence across Europe, Asia, and the US, Colt positions itself as a leading provider of high-performance, secure, and scalable network solutions tailored for enterprises. The website reflects a professional and well-branded digital presence with extensive content and customer testimonials supporting its market position. Technically, the website is built on WordPress hosted on WP Engine and protected by Cloudflare CDN. It leverages modern web technologies and marketing tools such as Gravity Forms, Google Tag Manager, HubSpot, and VWO for analytics and user engagement. The site is mobile optimized and accessible, with good SEO practices implemented. However, performance metrics are moderate, and some technical debt is evident in the SSL/TLS configuration. Security posture reveals critical issues: the SSL certificate is invalid or missing, and no TLS protocols are enabled, exposing the site to significant risks. While security headers are present, key features like HSTS, OCSP stapling, and session resumption are not enabled. No explicit security policy or incident response information is published, and privacy compliance is partial due to the absence of a cookie consent mechanism. Overall, Colt's website is trustworthy and professional but requires urgent remediation of SSL/TLS issues to ensure secure communications and compliance. Enhancing privacy compliance and publishing security policies would further strengthen trust and regulatory adherence.

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

8 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.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  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 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

Colt operates in the telecommunications and technology sectors, targeting enterprise customers needing managed network and voice services globally. Its business model focuses on delivering scalable, secure, and flexible connectivity solutions, including cloud and capital markets services. The company benefits from a mature domain and consistent branding, supported by numerous industry awards and certifications such as ISO 27001. The partnership ecosystem includes integrations with cloud providers and technology platforms. Growth indicators include a broad geographic footprint and a diverse service portfolio. The website's content and structure support lead generation and customer engagement through multiple contact forms and connectivity checkers.

Security posture

The current security maturity level is moderate to low due to the absence of a valid SSL certificate and disabled TLS protocols, which are critical for secure web communications. Security headers are implemented but not fully leveraged (e.g., HSTS is not enabled). There is no visible vulnerability disclosure or incident response information, which limits transparency and readiness. Privacy compliance is partial, lacking a cookie consent mechanism despite GDPR-relevant content. The site uses reputable hosting and CDN providers, which adds some security benefits. Overall, the security posture requires immediate improvement in SSL/TLS configuration and enhanced privacy and security policy disclosures.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate and enable HTTPS site-wide.
  2. Enable TLS 1.2 or higher and configure HSTS with includeSubDomains and preload flags.
  3. Implement a cookie policy and consent mechanism to comply with GDPR and privacy regulations.
  4. Publish a clear security policy and vulnerability disclosure program to enhance transparency.
  5. Enable OCSP stapling and session resumption to improve SSL performance and security.
Technical notes

Notes

The website is built on a modern WordPress CMS with a robust tech stack including WP Engine hosting, Cloudflare CDN, and multiple marketing and analytics tools such as Google Tag Manager, HubSpot, and VWO. The site is well-structured with comprehensive metadata, Open Graph tags, and JSON-LD structured data supporting SEO and social sharing. Performance is moderate with no explicit load time data but optimized images and responsive design indicate good user experience. Accessibility features and multi-language support are implemented. However, the invalid SSL certificate and disabled TLS protocols represent significant technical risks that could impact user trust and search rankings.
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.
