The website content reflects a mature B2B business model targeting enterprises requiring advanced connectivity and cloud solutions. Technically, the website leverages modern web technologies including Webflow CMS, Google Tag Manager, OneTrust for cookie consent, and other marketing and analytics tools, indicating a digitally mature infrastructure. Security posture is solid with HTTPS enforced and cookie consent mechanisms in place, though explicit security headers and incident response information are absent.

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

4 findings rated critical or high. Fix these first.

  1. 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';…

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 Technology Services operates in the telecommunications sector with a focus on enterprise digital infrastructure solutions. Its global footprint and service offerings such as SD-WAN, cloud connectivity, and security solutions position it competitively in the market. The company targets medium to large enterprises requiring reliable and scalable network services. The business model is B2B, with revenue likely driven by service contracts and managed solutions. The website's integration with Salesforce and other platforms suggests a robust CRM and customer engagement ecosystem. The lack of explicit contact details on the main site may indicate a controlled lead generation approach. The company maintains a consistent brand image and leverages trust signals such as Net Promoter Score (NPS) ratings. No direct partnerships or subsidiaries were identified from the data provided.

Security posture

The website enforces HTTPS and uses OneTrust for cookie consent, demonstrating compliance with GDPR and privacy best practices. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and others reduces the overall security posture. No security policy, incident response contacts, or vulnerability disclosure mechanisms were found, which are important for transparency and trust in enterprise environments. The use of modern analytics and marketing tools is balanced with consent management, but no direct evidence of vulnerability scanning or secure coding practices is visible. The missing WHOIS data raises questions about domain registration transparency but does not directly indicate compromise. Overall, the security posture is good but could be enhanced by publishing security policies and adding security headers.

Recommendations

  1. Publish a clear privacy policy and terms of service accessible from the main website.
  2. Add explicit security headers (Content-Security-Policy, X-Frame-Options, etc.) to improve protection against common web attacks.
  3. Provide clear contact information for security incidents and incident response.
  4. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Verify and update WHOIS domain registration information to ensure transparency and trust.

Technical notes

Notes

The website is built on Webflow CMS and uses a modern tech stack including Google Tag Manager, OneTrust for cookie consent, SwiperJS for UI components, and Intellimize for marketing optimization. The site loads resources from reputable CDNs and integrates with Salesforce platforms, indicating a well-structured digital infrastructure. Performance is moderate with good mobile optimization and basic accessibility features. SEO is supported by proper meta tags and structured data (JSON-LD). However, the site lacks some advanced accessibility features and explicit security headers. The absence of WHOIS data may indicate a need for domain registration review. Overall, the technical implementation is solid with opportunities for security and compliance enhancements.
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.
