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

Gradle Inc. operates the Gradle Build Tool website, providing a leading open source build system widely used by Java, Android, and Kotlin developers. The company offers a comprehensive ecosystem including professional services, educational resources like DPE University, and advanced tools such as Build Scan and Develocity. The website reflects a mature, well-established technology company with a strong market position and trusted by millions globally. Technically, the website is built with modern web standards, leveraging Cloudflare for DNS and likely CDN services, and integrates marketing automation tools like Pardot and Google Tag Manager. The site is fast, mobile-optimized, and accessible, with clear navigation and professional design. Structured data and metadata are well implemented to support SEO and social media presence. From a security perspective, the site enforces HTTPS, uses clientTransferProhibited domain status, and provides cookie consent mechanisms. However, it lacks DNSSEC, security headers, and published security policies or incident response contacts. No vulnerabilities or suspicious activities were detected, indicating a solid but improvable security posture. Overall, the website is trustworthy, professional, and compliant with privacy regulations such as GDPR. The domain WHOIS data aligns with the business claims, supporting legitimacy. Strategic improvements in security policy transparency and DNS security would further enhance trust and resilience.

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

5 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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. 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.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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.

    • 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

Gradle Inc. holds a strong position in the software development tools market, focusing on build automation for JVM and other languages. Its open source model combined with professional services and enterprise offerings creates diversified revenue streams. The company targets developers and enterprises seeking efficient build and automation solutions. Partnerships and community engagement through Slack, forums, and educational portals strengthen its ecosystem. The company's longevity since 2007 and top 20 open source ranking indicate sustained growth and competitive advantage in developer productivity tools.

Security posture

The website demonstrates a moderate to strong security posture with mandatory HTTPS and domain transfer protections. The absence of DNSSEC and security.txt or vulnerability disclosure pages suggests room for improvement in DNS security and transparency. No exposed sensitive data or vulnerable libraries were found. Cookie consent is implemented, supporting privacy compliance. Incident response contact information is not publicly available, which could hinder timely security communication. Overall, the security maturity is good but could be enhanced by adopting additional security headers and formal policies.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve overall DNS security.
  2. Publish a formal security policy and incident response contact information to improve transparency and trust.
  3. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Create and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Continue to maintain and enhance privacy compliance and cookie consent mechanisms in line with evolving regulations.

The website uses a clean, modern HTML5 and CSS3 codebase with JavaScript for interactivity, including a carousel and cookie consent banner. It leverages Google Tag Manager for analytics and Pardot for marketing automation. Hosting and DNS are managed via Cloudflare, providing performance and security benefits. The site is mobile-optimized and accessible, with structured data in JSON-LD format for organization and website schema enhancing SEO. No CMS or backend platform was explicitly detected, suggesting a custom or static site approach. Performance is fast with preconnect hints and deferred script loading.
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.
