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

MANTECH is an enterprise-level government and technology services company specializing in defense, intelligence, homeland security, and commercial sectors. Their website showcases a broad portfolio of expertise including cyberspace superiority, data and AI, digital transformation, and intelligent engineering. The company targets government agencies and commercial clients requiring advanced technology and security solutions. The website is professionally designed, mobile optimized, and structured for clear navigation, reflecting a mature digital presence. Technically, the site is built on WordPress 7.0.4 with integrations such as Google Tag Manager, Parsely analytics, and OneTrust cookie consent, indicating a modern and compliant infrastructure. Performance is moderate with good accessibility and SEO optimization. Security posture is strong with HTTPS enforced and cookie consent mechanisms in place, though additional security headers and explicit privacy and terms policies are recommended. The WHOIS data is unavailable or obscured, which reduces transparency and trustworthiness from a domain registration perspective. However, the website content and structure strongly indicate a legitimate and professional enterprise. No signs of blocking or WAF challenges were detected, allowing full content analysis. No explicit contact emails or phone numbers were found, which is a gap in user engagement and trust. Overall, MANTECH presents a solid business and technical profile with room for improvement in privacy disclosures and security transparency. Strategic recommendations include publishing comprehensive privacy and terms policies, adding security headers, and providing clear contact information for security incidents.

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

MANTECH operates as a government contractor and technology services provider with a focus on defense, intelligence, and homeland security markets. Their competitive advantage lies in a diversified portfolio of advanced cyber and digital transformation services, including specialized training programs and AI-driven solutions. The business model centers on long-term government contracts and partnerships, supported by a professional online presence and career recruitment platform. Growth indicators include a broad service offering and integration of modern technologies. The partnership ecosystem includes career portals and technology vendors. Strategic observations suggest a stable market position with opportunities to enhance trust through improved transparency and compliance documentation.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and cookie consent mechanisms implemented, reflecting compliance with basic privacy regulations. However, the absence of explicit privacy policy and terms of service pages, lack of security.txt or vulnerability disclosure information, and missing security headers such as Content-Security-Policy and X-Frame-Options represent compliance and security gaps. No exposed sensitive data or vulnerable libraries were detected. Incident response readiness is unclear due to missing contact channels. Overall, the security maturity is good but could be enhanced by formalizing policies and improving transparency to meet higher compliance standards such as GDPR and NIS2.

Recommendations

  1. Publish a comprehensive privacy policy page clearly accessible from the homepage.
  2. Add terms of service and security policy pages to improve legal and compliance posture.
  3. Implement and publish a security.txt file or vulnerability disclosure policy to facilitate responsible reporting.
  4. Enhance HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  5. Provide explicit contact information for security incidents and data protection officer if applicable.

Technical notes

Notes

The website is built on a modern WordPress CMS version 7.0.4, leveraging Google Tag Manager for marketing and analytics, Parsely for content analytics, and OneTrust for cookie consent management. The site uses JavaScript and CSS with responsive design techniques ensuring good mobile optimization and accessibility. Performance monitoring is implemented via Boomerang. The hosting provider is not explicitly identified. SEO practices are good with proper meta tags and structured data in JSON-LD format. Technical risks are minimal but could be reduced by updating security headers and ensuring all third-party scripts are regularly audited for vulnerabilities.
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.
