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

L-3 National Security Solutions group, Inc. operates as a defense and government contracting entity specializing in national security technology solutions. Their offerings include full-spectrum cyber operations, enterprise and mission IT, intelligence operations support, and operational infrastructure solutions. The company targets government agencies and defense sectors, positioning itself as an established provider with multiple contract vehicles and partnerships. The website content reflects a professional and consistent brand image, though some technical aspects are dated. Technically, the website is built on Joomla CMS and employs older JavaScript libraries such as jQuery 1.7.1 and MooTools, alongside deprecated Flash content. The site shows moderate performance and basic mobile optimization but lacks modern security headers and visible HTTPS enforcement. SEO and accessibility features are basic, indicating room for improvement in digital maturity. From a security perspective, the site does not expose sensitive data but uses outdated technologies that pose risks. The absence of privacy and cookie policies indicates compliance gaps, and no incident response or security policy information is provided. The WHOIS data aligns well with the business claims, supporting legitimacy. Overall, the security posture is moderate but requires enhancements to meet current standards. The overall risk assessment suggests the website is functional and credible but needs modernization and compliance improvements. Strategic recommendations include upgrading technology stacks, implementing security headers, enforcing HTTPS, and adding privacy and cookie policies to enhance trust and compliance.

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

10 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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

  4. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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

L-3 NSS is positioned as a key player in the government and defense technology sector, leveraging a broad portfolio of services tailored to national security needs. Their business model focuses on government contracting with multiple contract vehicles and a network of subsidiaries. The company benefits from established partnerships and a clear market presence. Revenue streams likely derive from long-term government contracts and specialized security solutions. The target customer segments include federal agencies, intelligence communities, and civil government entities. Growth indicators include recent press releases about significant task orders and partnerships. The company maintains a professional online presence but could improve transparency and digital engagement.

Security posture

The current security maturity level is moderate with notable gaps. The use of outdated JavaScript libraries and Flash content introduces potential vulnerabilities. The lack of security headers and unclear HTTPS status are significant concerns. No privacy or cookie policies are present, indicating non-compliance with GDPR and related regulations. Incident response readiness and security policy disclosures are absent, limiting transparency. While no direct vulnerabilities or exposed sensitive data were detected, the site would benefit from modernization and enhanced security controls to reduce risk and improve compliance.

Recommendations

  1. Upgrade all JavaScript libraries to current supported versions and remove Flash content to mitigate security risks.
  2. Implement comprehensive privacy and cookie policies with clear consent mechanisms to ensure GDPR compliance.
  3. Enforce HTTPS site-wide and configure essential security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  4. Publish a security policy and incident response contact information to improve transparency and trust.
  5. Enhance mobile optimization and accessibility features to improve user experience and broaden audience reach.

Technical notes

Notes

The website is built on Joomla CMS with a tech stack including MooTools and an outdated jQuery version (1.7.1). Flash video content is embedded, which is deprecated and unsupported by modern browsers, posing compatibility and security risks. The site uses CSS for styling and basic JavaScript for UI interactions. Performance is moderate with no explicit indicators of optimization or CDN usage. SEO is basic with meta tags present but no advanced structured data or Open Graph tags detected. Accessibility is minimal, and mobile responsiveness is basic. The technical debt is evident in legacy technologies and lack of modern security practices, suggesting a need for modernization to reduce operational 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.
