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.

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's market positioning as a leader in security and observability is reinforced by its comprehensive product portfolio and strong customer base, including notable enterprises like Children’s National Hospital, Progressive Insurance, and Singapore Airlines. The business model focuses on enterprise software and cloud services, with revenue streams from product licenses, cloud subscriptions, and professional services. The company targets IT, security, and engineering teams in large organizations seeking advanced analytics and AI capabilities. Partnerships with Cisco and integration with various platforms enhance its ecosystem. Growth indicators include continuous innovation in AI and observability, extensive customer success stories, and recognition in industry reports. The website's multi-language support and global reach indicate a broad international market presence.

Security posture

Splunk exhibits a strong security posture with comprehensive HTTP security headers including Content-Security-Policy, X-Content-Type-Options, Strict-Transport-Security, and X-Frame-Options. The SSL certificate is valid and issued by a trusted authority, DigiCert. However, the absence of TLS 1.2 or higher protocols is a notable gap, potentially exposing users to weaker encryption standards. DNSSEC and CAA records are not implemented, which could improve domain security. The presence of a dedicated security advisory site indicates proactive vulnerability disclosure and incident response capabilities. Privacy and cookie policies are comprehensive and GDPR compliant, with a consent mechanism in place. Overall, the security culture appears mature, but improvements in protocol support and DNS security are recommended.

Recommendations

  1. Enable TLS 1.2 and TLS 1.3 protocols to enhance encryption security.
  2. Implement DNSSEC to protect against DNS spoofing and improve domain integrity.
  3. Add CAA DNS records to restrict certificate authorities authorized to issue certificates for the domain.
  4. Consider submitting the domain to the HSTS preload list for improved HTTPS enforcement.
  5. Publish a security.txt file to facilitate responsible vulnerability disclosure.

Technical notes

Notes

The website is built on Adobe Experience Manager, utilizing modern JavaScript libraries and frameworks such as jQuery, Adobe Helix RUM, SignalFx RUM and Session Recorder, and Google Analytics for performance monitoring and user analytics. Hosting is primarily on AWS with Akamai CDN for content delivery, ensuring fast load times and global reach. The site is well optimized for mobile devices and accessibility, with good SEO practices including comprehensive metadata, Open Graph tags, and structured data in JSON-LD format. Some technical risks include the lack of modern TLS protocol support and absence of DNSSEC, which could impact security and trust. The use of multiple analytics and marketing tools indicates extensive user tracking, which is balanced by clear privacy and cookie policies.
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.
