About Cribl

Cribl sells the AI Platform for Telemetry to IT and security teams. Cribl says it was founded to address a problem in which telemetry was exploding while the tools to manage and search it were rigid, expensive, and siloed. Cribl started by giving customers a way to route and shape telemetry, so they could keep more data and send it to the right places. Cribl describes its platform as vendor-agnostic, with a telemetry engine to automate investigations. Cribl says telemetry data continues to grow at 28% a year and logging systems are at capacity. Cribl says its platform turns telemetry into a shared, reusable foundation for IT, security, and AI-driven operations.[4][6][7][10][11]

Cribl Stream integrates with 80+ sources and destinations, and portable Packs move entire pipelines as reusable bundles. Cribl Packs are bundles that package data routes, pipelines, and configurations. Collectors are fully supported in Cribl Packs for managing and shipping data from cloud, databases, and APIs. Copilot Editor in Cribl Stream maps schemas, transforms data, and filters data from plain language prompts.[1][7]

Cribl Stream offers dynamic sampling to filter events or roll up logs into metrics. Cribl Stream can keep a full-fidelity copy in low-cost storage or a data lake and replay it later. Cribl Guard uses AI to spot sensitive data, like credit cards or social security numbers, as it flows through Cribl Stream. Cribl Guard includes human-in-the-loop review, so operators can approve or override actions before data is masked or blocked. Cribl as Code gives security, IT, and engineering teams programmatic control to automate, configure, and manage their Cribl environment.[7][11]

Cribl Edge is a vendor-neutral agent for endpoint data collection. Cribl Edge is an agent for file monitoring, upgrades, and configurations that are managed through a GUI. Cribl Lake receives data that is less likely to be frequently used. Cribl Lake and Cribl Search are used for lower-cost retention and in-place search. Cribl Search is powered by a federated engine that searches data at rest and a lakehouse engine that searches data as soon as it is ingested. Cribl Search is a standalone offering, so Cribl Stream is not required to use it.[8][9][10]

Cribl Search searches data in place and supports data lakes, object stores, analytics services, API endpoints, and more. Cribl Search includes AI-guided incident investigations, collaborative Notebooks, AI-assisted KQL query generation, reporting, and visualizations.

Cribl Detect is offered as a SIEM. Cribl describes its SIEM approach as decoupling analysis from storage. Cribl Copilot Editor helps create pipelines using natural language to accelerate migration to new SIEMs and storage locations. Cribl Stream adds context to security data sources, like GeoIP, indicators of compromise, and any other threat intelligence database. Cribl supports storing data in low-cost object storage and replaying it to any destination for incident response. Cribl says most organizations route all telemetry, logs, metrics, and traces, into a single costly tier. Cribl supports routing frequently used data to SIEMs and observability tools, less-used data to a lakehouse, and data to an archive tier for retention requirements. Cribl supports delivering log management as a governed, multi-tenant shared service.[4][9][10][11]

Cribl offers a consumption-based model on its cloud platform, where Cribl Credits let customers allocate spending as demands change. Cribl offers volume-based licensing for Stream and Edge for customers who run their own infrastructure. Cribl offers multiple editions of its product suite. Enterprise customers get up to 3 Workspaces included for free, and additional Workspaces cost 250 credits per Workspace per month. FinOps Center tracks changes in data usage over time and ties them to events such as onboarding new sources or infrastructure shifts. Cribl Consulting Services provides advisory, delivery, optimization, and enablement work across a customer's Cribl environment, purchased through Service Credits.[12][13]

Cribl was formed in San Francisco, California. Cribl completed a Series A with $7.4M in funding and a Series B with $35M raised, led by Sequoia Capital. Cribl announced a Series C with $200M led by Greylock and Redpoint Ventures. Cribl secured $150M in Series D funding led by Tiger Global Management. Cribl closed a $319 million Series E at a $3.5 billion valuation. Cribl acquired CardinalOps to expand its AI platform into security operations. Cribl achieved FedRAMP Authority to Operate for U.S. federal government agencies.[2][4][7][10][12]
