Risk levelLow

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

ManTech International Corporation operates a professional and comprehensive website focused on providing advanced technology and cybersecurity solutions primarily to government, defense, and intelligence sectors. The company emphasizes digital transformation, data and AI, and intelligent engineering services. The website is well-structured, mobile-optimized, and integrates modern analytics and consent management tools, reflecting a mature digital infrastructure. Security posture is strong with HTTPS, security headers, and cookie consent mechanisms, though explicit security policies and incident response contacts are not publicly detailed. The absence of WHOIS data is a notable gap but does not detract significantly from the overall legitimacy given the professional presentation and government focus. Strategic recommendations include publishing detailed security policies and incident response information to enhance trust and compliance transparency.

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

No critical or high findings. These medium findings are worth fixing next.

  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.

    • Medium

      Missing Permissions-Policy header

      Controls browser features and APIs

      What to do: Implement a Permissions-Policy to restrict feature access

      • OWASP Secure Headers: OWASP Secure Headers Project recommends Permissions-Policy: accelerometer=(), autoplay=(), camera=(), cross-origin-isolated=(),…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Medium

      Privacy policy may not be GDPR compliant

      Privacy policy lacks explicit GDPR compliance elements

      What to do: Update privacy policy to explicitly address GDPR requirements and user rights

  3. 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.

    • Medium

      No MTA-STS Policy

      MTA-STS enforces TLS for email delivery

      What to do: Implement MTA-STS to prevent downgrade attacks

  4. 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.

    • Medium

      SSL Certificate Expires Within 90 Days

      SSL certificate expires in 49 days

      What to do: Plan SSL certificate renewal

    • Medium

      Mixed Content Detected

      1 resources loaded over insecure HTTP

      What to do: Ensure all resources (images, scripts, stylesheets) are loaded over HTTPS

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 positions itself as a key government contractor specializing in cybersecurity and digital mission support. Its business model is B2G, targeting federal agencies and defense organizations. The company leverages partnerships, such as with Avature for career management, and maintains a strong brand presence with consistent messaging and professional content. The website content and navigation cater to a knowledgeable audience seeking specialized technology services. The lack of publicly available WHOIS data suggests privacy protection or proxy registration, which is common but reduces transparency. Overall, ManTech demonstrates a stable market position with a focus on innovation and mission-critical services.

Security posture

The website employs HTTPS with good SSL configuration and implements multiple security headers, indicating a solid baseline security posture. Cookie consent is managed via OneTrust, supporting GDPR compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a dedicated security policy page and incident response contact information limits transparency and readiness perception. There is no evidence of a vulnerability disclosure program or security.txt file. Enhancing these areas would improve security maturity and stakeholder confidence.

Recommendations

  1. Publish a comprehensive security policy page detailing security practices and compliance.
  2. Provide clear incident response contact information, including security or abuse email addresses.
  3. Implement and publicize a vulnerability disclosure program or security.txt file.
  4. Regularly review and update third-party scripts and analytics tools to mitigate risks.
  5. Increase transparency around certifications and compliance frameworks to strengthen trust.

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.
