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

3 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.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 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

Leidos holds a strong market position as a systems integrator and technology provider with a global footprint and a workforce of approximately 47,000 employees. Their business model focuses on delivering mission-critical solutions across multiple sectors including government, defense, healthcare, and energy. The company leverages partnerships with major technology providers and maintains regional career portals indicating geographic diversification. Revenue streams likely include government contracts, technology services, and manufacturing. The website content and partner references suggest a well-established ecosystem and strategic growth orientation.

Security posture

The website employs HTTPS and integrates cookie consent, indicating baseline security and privacy awareness. However, the lack of explicit security headers (e.g., CSP, HSTS) and absence of published security policies or incident response contacts represent gaps in security maturity. No vulnerabilities or exposed sensitive data were detected in the content. The site would benefit from publishing a vulnerability disclosure policy and security.txt file to enhance transparency and incident readiness. Overall, the security posture is solid but could be improved with additional best practices and disclosures.

Recommendations

  1. Implement and publish a comprehensive privacy policy page to improve privacy compliance.
  2. Add security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-Content-Type-Options.
  3. Publish a security policy and incident response contact information to enhance trust and readiness.
  4. Create and maintain a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  5. Enhance WHOIS transparency or provide domain registration details to improve legitimacy perception.

Technical notes

The website is built on Drupal 10 CMS, utilizing modern JavaScript libraries and APIs including YouTube iframe API, Google Tag Manager, and Swiftype for search functionality. Lazy loading of images is implemented via LazySizes, improving performance. The site is mobile optimized and accessible with clear navigation and structured content.

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.
