Executive Summary

AI-generated analysis for Splunk

Splunk (splunk.com), a well-established data analytics vendor now operating under Cisco ownership, presents a low overall risk posture consistent with its Tier 4 rating.

Area Requiring Attention

The domain has been active for over 24 years, carries a clean reputation across 94 security engines, and shows no adverse media, sanctions concerns, or infrastructure exposure. The primary findings of note are a moderate HTTP security header configuration (HTTP security scanner grade C) and a vendor-attested CCPA compliance claim that lacks independent registry confirmation. For retail and e-commerce buyers deploying Splunk in or adjacent to the cardholder data environment, additional diligence is warranted around PCI-DSS shared responsibility documentation, formal CCPA/CPRA service provider agreements, and direct confirmation of SOC 2 Type II and PCI-DSS attestation status.

Independence Statement

All evidence underpinning this assessment was independently sourced from external data providers and public registries without vendor participation or input.

Steps to address findings for Splunk

  1. 1

    Confirm SOC 2 Type II attestation: Request Splunk's current SOC 2 Type II report directly from their security team or download it from https://trust.splunk.com (many enterprise vendors publish reports there under NDA). Verify the report covers the relevant trust service criteria (Security, Availability, Confidentiality) and that the audit period is current (within the last 12 months).

  2. 2

    Obtain PCI-DSS Attestation of Compliance (AOC): If Splunk will process, transmit, or store data in or adjacent to your cardholder data environment, request their current PCI-DSS AOC directly from their compliance or sales team. Confirm whether Splunk operates as a Level 1 PCI-DSS certified service provider and request the specific PCI SAQ or ROC scope applicable to your deployment.

  3. 3

    Execute a CCPA/CPRA-compliant Data Processing Agreement: Contact Splunk's legal or privacy team to obtain and execute a DPA that designates Splunk as a 'service provider' under CPRA, prohibiting data selling and cross-context behavioral advertising. Check https://trust.splunk.com for a standard DPA template. Complete within 30 days.

  4. 4

    Document PCI-DSS shared responsibility mapping: Per PCI-DSS 4.0 Requirement 12.8.5, create a written inventory specifying which PCI controls Splunk manages versus which your organization retains. Request Splunk's shared responsibility matrix or customer responsibility guide from their trust or compliance team — enterprise vendors typically provide this document for QSA engagements.

  5. 5

    Manually review the Splunk subprocessor list: Visit https://trust.splunk.com/subprocessors directly and document the subprocessors relevant to your deployment. Cross-reference key subprocessors against your organization's approved vendor list and confirm none appear on OFAC or EU sanctions lists. Retain this documentation for QSA fieldwork.

  6. 6

    Conduct a targeted sanctions screening verification: Because automated sanctions screening was unavailable during this assessment, manually verify Splunk (and its parent entity Cisco Systems) against the OFAC SDN list at https://sanctionssearch.ofac.treas.gov and the EU Consolidated Sanctions List. This is a low-effort, high-assurance step that can be completed within one business day.

Data Coverage Notes

Some data sources may have had limited availability during this assessment. This does not reflect negatively on the vendor.

  • Sanctions and watchlist screening was unavailable during this assessment. Manual verification against OFAC, EU, and UN sanctions lists is recommended as a precautionary step.
  • SSL/TLS deep analysis (cipher suites, protocol support, certificate chain validation) could not be completed — only the surface-level certificate details from the domain scan are available.
  • Certificate transparency log analysis was unavailable, so a complete subdomain inventory and certificate issuance history could not be assessed.
  • Splunk's published subprocessor page at trust.splunk.com was detected but could not be parsed into structured entries due to a non-standard page format. Individual subprocessor entities were not screened for sanctions or safety issues during this assessment.
  • External cyber risk scoring was not available, limiting the ability to benchmark Splunk's security posture against industry peers.

Can I get an auto-filled security questionnaire for Splunk?+

The questionnaire is mapped to SIG, SOC 2, HIPAA, PCI DSS and 9 other frameworks — answered without sending Splunk a single email or waiting for a vendor response.
Is Splunk safe to use as a vendor?+
Splunk is a observability vendor that handles application logs, traces, and metrics. Safety depends on their current security posture, certification status, and how they handle your specific data. ThirdProof automates this evaluation across 27 intelligence sources — sanctions databases (OFAC, EU, UN), business registration verification, adverse media scanning, and cyber risk assessment — producing a deterministic risk tier with confidence score plus an auto-filled security questionnaire. Run a free investigation to see Splunk's full risk profile.
Does Splunk have SOC 2 certification?+
No SOC 2 found. Splunk rated Moderate Risk — subprocessor page incomplete. See all 4 findings →
Has Splunk had any data breaches?+
Data breach history is an important signal for any vendor, particularly observability platforms like Splunk that handle application logs, traces, and metrics. ThirdProof's adverse media analysis searches multiple news APIs and public records for data breaches, security incidents, lawsuits, regulatory enforcement actions, and financial distress signals. Each finding is linked to its original source with severity classification.
Is Splunk on any sanctions lists?+
Sanctions screening is standard due diligence for observability vendors. ThirdProof screens Splunk against OFAC SDN, consolidated international sanctions lists, and PEP databases. The screening uses entity name verification to reduce false positives. If Splunk or any associated officers appear on a sanctions list, this triggers automatic escalation to the highest risk tier.
How do I assess Splunk for vendor risk?+
Assessing Splunk as a observability vendor involves verifying SOC 2 Type II and FedRAMP compliance, reviewing their subprocessor chain, and checking sanctions exposure. ThirdProof automates this across 27 intelligence sources in an average of 7 minutes — no questionnaires or vendor participation required. Your first 5 investigations are free.
How long does a ThirdProof assessment take?+
A ThirdProof assessment completes in an average of 7 minutes. 27 intelligence sources are queried in parallel — sanctions databases, business registries, threat intelligence feeds, certificate transparency logs, and more. The result is a deterministic risk tier with confidence score and audit-ready PDF report.
Is ThirdProof free?+
ThirdProof offers 5 free vendor assessments with no credit card required. Each assessment includes the full report — risk tier, confidence score, individual findings, executive summary, and PDF export. Paid plans start at $399/month for teams that need ongoing vendor monitoring.
Can I use a ThirdProof report as SOC 2 audit evidence?+
Yes. ThirdProof reports are designed to satisfy SOC 2 CC9.2 (vendor risk management) requirements. Each report includes SHA-256 integrity verification, methodology disclosure, source attribution for every finding, and AI content labeling. Auditors can independently verify the report's authenticity and trace each finding to its original source.
How is ThirdProof different from a security questionnaire?+
Security questionnaires require vendor participation, take weeks, and produce self-reported answers. ThirdProof queries 27 independent intelligence sources — no vendor involvement needed. Risk tiers are assigned by a deterministic rules engine (not AI opinion), and every finding links to its original source. You get an audit-ready report in an average of 7 minutes instead of waiting weeks for a questionnaire response.

Splunk is in your vendor stack. Can you prove you assessed them?

SOC 2 CC9.2, HIPAA, PCI-DSS, and CMMC all require documented vendor due diligence — not just knowing the answer, but having audit-ready evidence you verified it. Most compliance teams can't produce that documentation on demand.

ThirdProof investigates Splunk across 27 intelligence sources in an average of 7 minutes — sanctions screening, cyber posture, SOC 2 verification, FedRAMP status, and more. Every investigation produces two deliverables: an audit-ready risk report and an auto-filled security questionnaire your prospects and auditors expect to see.
