The SIEM that
sees the attack
before it lands.
Community-built. Production-hardened. Ingests 4M events/sec, correlates lateral movement chains in real time, and surfaces what commercial SIEMs bury in noise — without the six-figure invoice.
By the numbers
Built for production.
Not for demos.
Capability
From log chaos
to attack chain
in milliseconds.
Sentinel's correlation engine doesn't just alert — it reconstructs the full attack narrative. SOC analysts see the complete kill chain, not 847 individual alerts.
Four layers.
One attack chain.
Sentinel's pipeline transforms millions of raw log lines into a single, actionable incident — without losing the evidence trail.
Ingest & Normalize
Kafka topics receive logs from every source. Parsing pipelines normalize to ECS schema in real time.
Enrich & Contextualize
IOC matching, geo-lookup, asset inventory join, and threat intel enrichment happen at ingestion time.
Correlate Across Time
Sliding-window correlation engine links signals across 24-hour windows. Temporal context surfaces kill chains.
Fire & Respond
Rule matches trigger alerts with full context. Playbooks auto-respond. Analysts see signal, not noise.
Multi-stage Correlation
Chain low-fidelity signals across time windows into high-confidence attack narratives. Reduce alert volume by 94%.
MITRE ATT&CK Mapping
Every detection rule tagged to ATT&CK tactics and techniques. Navigator export in one click.
Detection-as-Code
Write Sigma rules in YAML, test in CI, deploy via GitOps. Your detections live in version control.
Automated Playbooks
Trigger Jira tickets, PagerDuty pages, or custom webhooks the moment a rule fires. Zero manual triage.
Cloud-Native Ingestion
Native connectors for AWS CloudTrail, GCP Audit Logs, Azure Sentinel, Kubernetes audit, and 40+ sources.
Threat Intelligence Feeds
Enrich detections with AlienVault OTX, Abuse.ch, and custom STIX/TAXII feeds. IOC matching at ingestion time.
Community
Built by SOC analysts,
for SOC analysts.
Every detection rule comes from someone who was paged at 3am because of it. This is security software written by the people who use it.

“We replaced a $340k/year Splunk contract with Sentinel in six weeks. Detection coverage went up. Alert fatigue went down. My team actually sleeps now.”
“The detection-as-code workflow is what sold me. We test Sigma rules in CI before they ever hit production. No more 3am pages from a broken rule.”
“As a 12-person startup, we needed enterprise-grade SIEM. Sentinel gave us MITRE coverage, cloud log ingestion, and a correlation engine in one afternoon.”
Zero Friction Deploy
No form. No sales call.
Just a running SIEM.
