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

CACI is an established enterprise technology company specializing in connecting data, technology, and human insight to deliver scalable, innovative solutions that drive business transformation and operational excellence. The company targets business and government clients seeking advanced data analytics, AI, and technology consulting services. The website demonstrates a mature digital presence with professional design, comprehensive navigation, and strong SEO implementation. Technically, the site is built on WordPress with modern libraries and includes cookie consent and analytics integrations, reflecting a good level of digital maturity. Security posture is solid with HTTPS and consent mechanisms, though improvements are recommended in security headers and explicit security policies. WHOIS data for the exact domain queried is unavailable due to it being a subdomain, which slightly impacts trust but does not detract from the overall legitimacy given the professional content and branding. Strategic recommendations include enhancing security headers, publishing clear privacy and security policies, and providing direct contact information for security and privacy inquiries.

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

2 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
    • 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

CACI operates in the technology sector with a focus on data-driven solutions including AI, analytics, logistics optimization, and technology consulting. The company appears to have a strong market position as a trusted enterprise provider with a broad portfolio of services targeting large organizations. The business model is B2B, leveraging data and technology to deliver actionable insights and transformation. The website content and structured data confirm a consistent brand identity and professional approach. Partnerships and integrations with platforms like HubSpot and Google indicate a mature marketing and analytics ecosystem. No direct contact or subsidiary domains were identified in the provided data.

Security posture

The website enforces HTTPS and uses a cookie consent mechanism compliant with GDPR principles, indicating a baseline of privacy and security awareness. However, no explicit security headers were detected in the provided data, and no published security policy or incident response contacts were found. The use of third-party analytics and marketing tools introduces moderate tracking but is managed with consent. The absence of a vulnerability disclosure or security.txt file suggests room for improvement in transparency and incident readiness. Overall, the security posture is good but could be enhanced by implementing recommended headers, publishing security policies, and providing clear security contact channels.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to harden the website against common attacks.
  2. Publish a clear security policy and incident response contact information on the website to improve transparency and trust.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Ensure all third-party scripts and libraries are regularly updated and monitored for vulnerabilities.
  5. Provide explicit contact details for privacy and security inquiries to enhance user trust and compliance.

Notes

The website is built on WordPress and uses modern JavaScript libraries such as jQuery 3.7.1 and Splide.js for UI components.

Google Tag Manager is deployed for analytics and marketing tag management. The site is mobile-optimized with responsive design and accessibility features.

Overall, the technical infrastructure supports a professional and scalable web presence.
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.
