Keyword Tool is a well-established online keyword research platform founded in 2014 and operated by Key Tools Limited based in Hong Kong. It offers a freemium SaaS model providing keyword suggestions primarily using Google Autocomplete data, targeting marketers, business owners, and content creators globally. The website is professionally designed, mobile-optimized, and features extensive content supporting SEO and PPC keyword research across multiple search engines and languages. The platform holds a strong market position as a reliable alternative to Google Keyword Planner, supported by reputable customer logos and media endorsements. Technically, the site leverages modern web technologies including Cloudflare CDN, Google Tag Manager, Microsoft Clarity, and VWO for analytics and optimization, ensuring fast performance and good accessibility. Security posture is strong with HTTPS enforced and domain transfer protections, though DNSSEC is not enabled and explicit security policies or incident response contacts are not publicly disclosed. Privacy compliance is adequate with a comprehensive privacy policy but lacks a cookie consent mechanism. Overall, the website is trustworthy, secure, and professionally maintained, suitable for its target audience and business model.

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 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 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

Keyword Tool operates in the technology sector providing keyword research tools that support SEO and PPC marketing efforts. Its freemium business model includes a free tier and paid Pro subscriptions, as well as API access for enterprise clients. The company targets digital marketers, content creators, and businesses seeking to optimize their online presence internationally. The presence of multiple language and country options indicates a global market approach. The website's trust signals, including customer logos from major brands and positive media quotes, enhance credibility. The company maintains physical offices in Hong Kong and UAE, with clear registration details. The platform's integration with payment and analytics services suggests mature operational capabilities. No suspicious or fraudulent patterns were detected in domain registration or website content.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and domain status set to clientTransferProhibited, preventing unauthorized transfers. Use of Cloudflare CDN adds DDoS protection and performance benefits. Security headers are likely implemented though not explicitly visible in HTML. No sensitive data exposure or vulnerable libraries were detected. However, DNSSEC is not enabled, which could improve DNS security. The absence of a security.txt file and incident response contact information limits transparency for vulnerability reporting. Privacy policy is comprehensive and GDPR compliant, but no cookie consent banner was detected, which is a minor compliance gap. Overall, the site is secure but could improve transparency and DNS security.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement a cookie consent mechanism to improve GDPR compliance and user privacy transparency.
  3. Publish a security policy and incident response page including security contact emails (e.g., security@ or abuse@).
  4. Add a security.txt file at the root domain to facilitate responsible vulnerability disclosure.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities or outdated components.

Technical notes

Notes

The website uses a modern technology stack including ES modules, Bootstrap CSS, and integrates multiple analytics and optimization tools such as Google Tag Manager, Microsoft Clarity, and Visual Website Optimizer. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. The site is mobile-optimized with responsive design and fast loading times. SEO is well addressed with proper meta tags, Open Graph, Twitter cards, and structured data (JSON-LD) for organization and FAQ. No CMS is explicitly detected, suggesting a custom or static site build. The technical implementation is robust with minor opportunities for improvement in DNS security and explicit security headers.
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.
