Cribl

Cribl is the AI Platform for Telemetry, giving organizations a flexible way to collect, process, route, store, search, and analyze the logs, metrics, traces, events, and other machine data generated across modern IT and security environments. Built for the volume, variety, and changing value of telemetry, Cribl helps teams make better use of the data customers already have without forcing them into a single vendor, destination, data format, or architecture. The platform brings together complementary products and capabilities: Cribl Stream provides real-time observability pipelines that collect data from diverse sources, then filter, reduce, transform, enrich, and route it to the tools that need it; Cribl Edge extends intelligent collection and processing to servers, endpoints, applications, and other distributed environments through centralized fleet management; Cribl Search enables federated, search-in-place investigations across data wherever it lives, reducing the need to centralize or rehydrate everything before it can be analyzed; and Cribl Lake provides open, cost-effective storage for retaining, accessing, and replaying telemetry over time. Cribl.Cloud offers a fully managed way to deploy and operate these capabilities, while Cribl’s app-building and AI capabilities help teams create workflows tailored to the way they investigate, troubleshoot, secure, and operate their environments. Together, these capabilities give IT, security, platform engineering, and SRE teams control over the complete telemetry lifecycle—from collection and onboarding through transformation, delivery, retention, and investigation. The primary value is choice and control: teams can send the right data to the right destination in the right format, reduce unnecessary volume and infrastructure cost, preserve valuable data for future questions, and search across systems without being constrained by the limitations of any one tool. By providing a vendor-agnostic data layer between sources, storage, analytics platforms, and AI-driven workflows, Cribl helps organizations improve data quality, accelerate investigations and incident response, simplify operations, support modernization initiatives such as SIEM migration, and build an AI-ready foundation while protecting existing technology investments. In short, Cribl turns complex, distributed telemetry into a governed and usable resource that both people and intelligent systems can trust and act on.

Estuary

Estuary, formerly known as Estuary Flow, is the dependable Right-Time Data Platform that unifies CDC, batch, streaming, and app-sync pipelines into one managed system. Instead of stitching together brittle stacks like Kafka + Debezium or juggling separate ELT, CDC, and streaming tools, you get a single platform that powers analytics, operations, and AI with the cadence and cost control you choose. Move data at the right time for the job: sub-second for operations and AI, near-real-time for applications, or scheduled batch for analytics. Estuary lets you dial latency up or down without changing tools or paying unpredictable MAR-based pricing. Deploy anywhere — SaaS, BYOC, or fully private — with enterprise-grade reliability, exactly-once semantics, deterministic recovery, and strong compliance. And with Kafka API compatibility, Estuary plugs into your existing ecosystem without the operational burden of running Kafka. With Estuary, you get predictable pricing, flexible deployment, and pipelines that "just work": delivering dependable data for analytics, operations, and AI.
