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

1 finding 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 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

Mandiant operates as an essential entity within the cybersecurity industry, focusing on threat intelligence and incident response services. Its integration with Google Cloud enhances its market reach and credibility. The business model centers on providing expert consulting, managed detection and response, and AI security services to enterprise and government clients. Revenue streams likely include consulting fees, managed service subscriptions, and training programs. The company maintains a strong partnership ecosystem, primarily with Google Cloud, and actively engages customers through comprehensive resources and thought leadership content. Growth indicators include frequent publication of cybersecurity reports and expansion into AI security consulting. The website's professional design and extensive service offerings reflect a mature and well-established market presence.

Security posture

Mandiant exhibits a mature security posture with enforced HTTPS, use of reCAPTCHA, and comprehensive privacy and cookie policies. The site avoids exposing sensitive information and integrates security best practices in form handling and data collection. However, explicit security headers such as X-Frame-Options and X-Content-Type-Options are not clearly identified and should be verified. There is no evidence of vulnerability disclosure programs or security.txt files, which could enhance transparency and incident response readiness. Compliance with GDPR is indicated through cookie consent and privacy policy references. Overall, the security culture appears strong, supported by the company's frontline expertise and incident response capabilities.

Recommendations

  1. Verify and explicitly implement security headers like X-Frame-Options and X-Content-Type-Options to enhance protection against clickjacking and MIME sniffing.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure and improve transparency.
  3. Regularly audit third-party scripts and marketing tools to mitigate supply chain risks.
  4. Enhance visibility of incident response contact channels on the website for faster communication.
  5. Continue to update privacy and cookie policies to reflect evolving regulations and maintain GDPR compliance.

Technical notes

Notes

The website is built on Drupal CMS and hosted on Google Cloud, leveraging a modern technology stack including Google Tag Manager, Google Analytics, Marketo, Hotjar, and various social media tracking pixels. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, likely influenced by the number of third-party scripts and rich media content. Structured data using JSON-LD enhances SEO and content discoverability. Technical risks include potential vulnerabilities from third-party marketing and analytics scripts, which require ongoing monitoring. The absence of explicit security headers is a minor technical debt that should be addressed to improve security posture.
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.
