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

DomainTools is a leading provider of internet and domain intelligence solutions, serving a broad range of enterprise customers including government agencies, financial institutions, healthcare organizations, and technology companies. Their platform offers comprehensive threat intelligence, domain monitoring, and integrations with major security tools such as SIEM and SOAR platforms. The company positions itself as a critical layer in the cybersecurity stack, trusted by many Fortune 100 companies and government entities. Technically, the website is built on WordPress using the Enfold theme, with modern SEO and analytics tools integrated, including Google Tag Manager, Microsoft Clarity, and LinkedIn Insight. The site is well-optimized for mobile and accessibility, with fast performance and a professional design. Security best practices are observed with HTTPS enforcement and appropriate security headers. While the WHOIS data is unavailable, likely due to registry restrictions or privacy, the website's professional presentation and market presence support its legitimacy. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms suggests areas for improvement in transparency and security communication. Overall, DomainTools demonstrates a strong security posture and digital maturity, with recommendations to enhance security policy disclosures and direct security contact information to further build 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

4 findings rated critical or high. Fix these first.

  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.

    • 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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…
  2. 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

  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.

    • 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

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

DomainTools operates in the cybersecurity and internet intelligence market, focusing on domain and threat intelligence services. Their business model is subscription-based, offering data feeds, investigative tools, and integrations that enhance enterprise security operations. The company has a strong market position, serving over 700 enterprise customers, including a significant portion of the Fortune 100 and major government agencies. Their partnership ecosystem includes integrations with leading security platforms, enhancing their competitive advantage. Growth indicators include a broad product portfolio and active content marketing through blogs, webinars, and reports. The company targets security teams in various sectors, emphasizing proactive threat detection and brand protection.

Security posture

The website enforces HTTPS and implements key security headers, indicating a mature security posture. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a published security policy, incident response contact details, and vulnerability disclosure program limits transparency and may impact incident handling readiness. GDPR compliance is indicated through privacy and cookie policies with consent mechanisms. The security culture appears professional but could benefit from enhanced communication of security practices and direct security contacts to improve stakeholder confidence.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and compliance.
  2. Provide explicit incident response contact information, including security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure program or security.txt file.
  4. Enhance transparency by listing the Data Protection Officer contact details.
  5. Regularly review and audit third-party scripts and integrations for security vulnerabilities.

Technical notes

Notes

The website is built on a modern WordPress CMS with the Enfold theme, leveraging a variety of JavaScript libraries and analytics tools such as Google Tag Manager, Microsoft Clarity, and LinkedIn Insight. The site demonstrates fast loading times, excellent mobile responsiveness, and good accessibility features. SEO is well-implemented with Yoast SEO plugin and comprehensive meta tags including Open Graph and JSON-LD structured data. The technical infrastructure supports a professional and scalable digital presence, though hosting provider details were not explicitly identified. Opportunities exist to further modernize by reducing third-party script dependencies and enhancing security disclosures.
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.
