75/100

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

JetBrains is a leading software vendor specializing in intelligent development tools such as IntelliJ IDEA and the Kotlin programming language. The company targets software developers and teams, offering a broad portfolio of IDEs, team collaboration tools, and AI-powered developer solutions. Their market position is strong, supported by a professional and content-rich website that reflects their technology focus and innovation leadership. The technical infrastructure includes modern JavaScript frameworks, Google Tag Manager, and Optimizely for analytics and experimentation, alongside a robust cookie consent mechanism ensuring GDPR compliance. Security posture is solid with HTTPS enforced and error reporting mechanisms, though explicit security headers and vulnerability disclosure policies are absent. Overall, the website demonstrates high professionalism, excellent user experience, and strong privacy compliance, though WHOIS data is unavailable, which slightly impacts domain trust assessment.

Scanned

5 of 7 checks could not complete. The site may be unreachable or blocking automated scans, so the results below cover only what could be checked. Try a rescan later.

NIS2 and GDPR posture

NIS2 outside view

GDPR outside view
Not assessed

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

1 finding rated critical or high in the checks that completed. 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 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

  • Security headers: did not complete in this scan.
  • DNS health: did not complete in this scan.
  • Network security: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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

JetBrains operates in the technology sector, focusing on software development tools and team solutions. Their business model revolves around software licensing and subscriptions for individual developers and organizations. The company maintains a comprehensive ecosystem including IDEs, plugins, AI assistants, and educational offerings. Their global presence is indicated by multilingual site versions and localized contact numbers. JetBrains leverages partnerships and integrations with major platforms and maintains active social media channels for community engagement. The absence of WHOIS data is unusual but does not detract from the evident market leadership and brand strength. Growth indicators include continuous product innovation and AI integration.

Security posture

The website employs HTTPS and includes cookie consent banners aligned with GDPR requirements, indicating a mature privacy approach. Error reporting and analytics scripts are implemented with user consent checks. However, the lack of explicit security headers (e.g., Content Security Policy, HSTS) and absence of a public security policy or incident response page suggest areas for improvement. No vulnerability disclosures or security.txt files were found, limiting transparency in security incident handling. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. Overall, the security posture is good but could be enhanced by adopting additional best practices and public security documentation.

Recommendations

  1. Implement and publish explicit security headers such as CSP, HSTS, and X-Frame-Options to strengthen browser security.
  2. Create and maintain a public security policy and incident response page to improve transparency and trust.
  3. Establish a vulnerability disclosure program and publish a security.txt file to facilitate responsible reporting.
  4. Consider deploying DNSSEC to enhance domain name system security.
  5. Verify and update WHOIS information to ensure domain registration transparency and trustworthiness.

Technical notes

Notes

The website uses modern JavaScript frameworks and integrates third-party services like Google Tag Manager and Optimizely for analytics and A/B testing. CookieHub manages cookie consent, ensuring compliance with privacy regulations. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, with room for optimization. No CMS was detected, suggesting a custom or proprietary platform. Hosting provider details are not evident from the content. The technical stack supports a professional and scalable web presence, though improvements in security headers and DNS configuration could reduce technical risks.
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.
