Legacy SIEM economics force security teams into a dangerous compromise: choose which telemetry you can afford to investigate, or bankrupt your budget on hot-tier storage. To survive, critical data gets dropped or sampled, creating massive blind spots when an incident strikes. Enter Rover. Rover is an Agentic SIEM built for machine-speed attacks. We combine autonomous AI agents with an S3-native search architecture, allowing you to investigate telemetry directly from your data lake without forcing every byte into an expensive SIEM hot tier. Why SecOps Leaders Choose Rover: • Agentic Workflows: Rover agents do the repetitive work. They gather evidence, test hypotheses, and turn isolated alerts into complete, evidence-cited attack narratives. • S3-Backed Investigation: Keep your searchable memory in S3. Run searches over S3-hosted indices so older and lower-frequency telemetry remains useful during incidents—drastically lowering costs. • Adaptive Detections: Generic rules just create noise. Rover learns your behavioral baselines and adapts detections to your environment so you only see signals that actually matter. • Machine-Speed Context: Correlate activity across identity, cloud, endpoint, and audit sources instantly. The Rover Advantage: The modern adversary moves too fast for manual context gathering. Rover treats alert triage as an autonomous workflow. Agents gather the evidence and propose decisions; analysts approve the response and improve defenses. Stop dropping your telemetry. Start reasoning over it at machine speed.
