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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

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

Splunk operates in the technology sector, focusing on data analytics, security, and observability solutions for enterprises. Its business model is primarily B2B, offering software and cloud services that enable organizations to monitor, analyze, and secure their IT environments. The company has a strong market presence with a broad portfolio of products and use cases spanning artificial intelligence, blockchain monitoring, compliance, and IT modernization. Revenue streams likely include software licenses, cloud subscriptions, and professional services. Splunk’s partnership with Cisco and ownership of AppDynamics enhance its competitive advantage. The company targets large enterprises across multiple industries, emphasizing digital resilience and operational intelligence. Growth indicators include continuous product innovation, extensive resource offerings, and global multi-language support.

Security posture

Splunk exhibits a mature security posture with multiple layers of protection. The website enforces HTTPS with strong SSL/TLS configurations and implements key security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security. The presence of a dedicated security advisory site and incident response contacts indicates readiness to handle vulnerabilities and threats. No exposed credentials or sensitive data were found in the website content. Privacy policies and cookie consent mechanisms align with GDPR requirements. However, the absence of a security.txt file and explicit Data Protection Officer contact details are minor gaps. Overall, the security culture appears robust, supporting business continuity and customer trust.

Recommendations

  1. Publish a security.txt file at the root domain to facilitate vulnerability reporting.
  2. Provide explicit Data Protection Officer contact information to enhance GDPR transparency.
  3. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.
  4. Enhance documentation of data retention policies related to analytics and user data.
  5. Continue to monitor and improve accessibility and mobile optimization to maintain high user experience standards.

Notes

The website is built on Adobe Experience Manager CMS, leveraging modern web technologies including jQuery, Google Analytics, Google Tag Manager, and SignalFx Real User Monitoring.

The site demonstrates fast loading times, mobile responsiveness, and good SEO practices with comprehensive meta tags and structured data. Navigation is clear with multi-language support and well-organized content. Technical risks are minimal, with no detected outdated or vulnerable libraries. Opportunities exist to further modernize by adopting newer JavaScript frameworks and enhancing automation in deployment pipelines.
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.
