Vanta vs Splunk
Side-by-side comparison of AI visibility scores, market position, and capabilities
Leading compliance automation platform with $1.6B valuation; continuous control monitoring for SOC 2 and ISO 27001 serving thousands of SaaS companies competing with Drata and Sprinto.
About
Vanta is a trust management platform that automates security compliance for companies seeking SOC 2, ISO 27001, HIPAA, GDPR, PCI DSS, and other certifications — continuously monitoring security controls, collecting evidence automatically, and streamlining the audit process. Founded in 2018 by Christina Cacioppo and Fred Bloch in San Francisco, Vanta has raised over $250 million at a $1.6 billion valuation and serves thousands of companies — primarily high-growth SaaS startups that need compliance to close enterprise deals — making it the category leader in compliance automation.\n\nVanta connects to a company's cloud infrastructure (AWS, GCP, Azure), identity providers (Okta, GSuite), code repositories (GitHub, GitLab), HR systems, and endpoint management tools to automatically collect compliance evidence. When an employee joins or leaves, Vanta automatically tracks whether access provisioning and de-provisioning is happening correctly. When a security scan runs, Vanta pulls the results as evidence. The platform then maps this collected evidence to the specific controls required for each compliance framework and alerts security owners when controls fall out of compliance.\n\nIn 2025, Vanta leads the compliance automation category, competing with Drata, Sprinto, Secureframe, and Tugboat Logic (OneTrust) for the growing market of companies that need compliance certifications to satisfy enterprise procurement requirements. The market has expanded beyond SOC 2 — Vanta's trust reports and vendor risk management products help companies share their security posture with customers and manage third-party vendor risks. The 2025 strategy emphasizes expanding beyond compliance into broader security and trust management, growing enterprise customer adoption (moving beyond startup-focused positioning), and launching AI-powered compliance gap remediation recommendations.
Data platform for security and observability acquired by Cisco for $28B in March 2024. Used by 90 of Fortune 100; 7,500+ enterprise customers globally; flagship SIEM and Splunk SOAR power enterprise security operations centers.
About
Splunk is a data platform for security and observability founded in 2003 in San Francisco, built on the idea that machine-generated data — logs, events, metrics, traces — contains the intelligence organizations need to detect threats, investigate incidents, and ensure digital systems stay available. The company's core technology indexes and searches massive volumes of machine data in real time, enabling security and IT operations teams to answer complex questions across their entire data estate without predefined schemas.\n\nSplunk's flagship product is its SIEM (Security Information and Event Management) platform, used by 90 of the Fortune 100 to detect and respond to security threats. Its broader portfolio includes Splunk Observability Cloud for infrastructure monitoring, Splunk SOAR for security orchestration and automated response, and Splunk IT Service Intelligence for IT operations. The platform's schema-on-read approach and SPL query language give analysts flexibility to investigate novel threats and operational issues that structured databases cannot accommodate.\n\nSplunk was acquired by Cisco for $28B in March 2024, one of the largest cybersecurity acquisitions in history, and has been integrated into Cisco's AI-driven security portfolio. The combination of Cisco's network telemetry and global customer relationships with Splunk's data analytics depth creates a powerful full-stack security and observability offering. Under Cisco, Splunk is adding AI-native features — including AI Assistant for SPL and automated threat detection — to maintain its leadership position as the SIEM market evolves toward AI-augmented security operations.
