About
Doppler is a secrets management platform founded in 2019 and headquartered in San Francisco, California. The company was founded by Brian Vallelunga and Ryan Blunden to solve a problem endemic to software development teams: secrets sprawl. Environment variables, API keys, database connection strings, and other configuration secrets routinely end up hardcoded in source code, scattered across .env files, sent over Slack, or duplicated inconsistently across development, staging, and production environments. Doppler provides a central secrets store where teams manage all configuration secrets in one place and sync them automatically to every environment.\n\nDoppler raised $20 million in funding from investors including Sequoia Capital and CRV. Its developer-first platform integrates with CI/CD pipelines, cloud platforms, and deployment tools so that secrets flow automatically to where they are needed without manual copying or environment-specific .env file management. The Doppler CLI allows developers to run applications locally with secrets injected from the central store, eliminating local .env files entirely. The platform supports fine-grained access controls, secret versioning, change history, and audit logs, enabling security teams to govern who can read or modify secrets without slowing down developers.\n\nDoppler's integrations cover AWS Secrets Manager, Google Secret Manager, Azure Key Vault, HashiCorp Vault, GitHub Actions, GitLab CI, CircleCI, Heroku, Vercel, Render, and many other platforms. Teams can use Doppler as their primary secrets store or as a secrets sync layer that propagates secrets from Doppler into their preferred secrets backend. The platform serves engineering teams from startups to enterprises, with a free tier for small teams and enterprise plans with SSO, compliance controls, and dedicated support.
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.
