Sentry is the operations layer your analysts actually live in: a petabyte log lake, detections versioned in git, response automated in playbooks, and every case from first alert to after-action on a single timeline. Stop swivel-chairing between nine consoles at 3 a.m.

$ _Trusted on the night shift by teams that can't afford a miss
Sentry isn't another box that throws alerts over the wall. It's the workbench your analysts work the case in — ingest, detect, triage, respond, and document, all on one correlated timeline.
Stream every endpoint, identity, cloud, and network event into a columnar lake built on object storage. Query a year of history in seconds with full-text and field search, hold 90 days hot and 13 months warm, and pay for the compute you run — never per gigabyte ingested. Sources land over OTLP, syslog, HTTP, or a bucket you already own.
Author rules in YAML and Sigma, test them against replayed history, and ship them through the same git workflow as the rest of your stack. Every detection is versioned, peer-reviewed, and one revert away from rolled back.
Correlated signals fuse into one case, ranked by blast radius and confidence. Your analysts open ten investigations a day instead of drowning in a thousand alerts.
Isolate a host, revoke a session, or block an indicator from a versioned playbook — fired on trigger or one keystroke from the open case.
Pivot across the whole lake, save the hunt, schedule it to re-run nightly, and graduate a good one straight into a production detection.
What one shift on Sentry measures out to
Sentry runs inside your environment and speaks the protocols you already emit. No proprietary agent to roll out, no telemetry shipped to a vendor cloud, no rip-and-replace of the SIEM you just bought.
OTLP, syslog, CloudTrail, Okta, Entra, Kubernetes audit, and raw S3 buckets land natively. Keep every collector you run today.
Rules live in a repo with CI, code review, and a changelog. Promote staging to prod with a merge; roll back with a revert.
Deploy single-tenant in your own cloud or air-gapped on-prem. Logs, cases, and forensics never co-mingle and never leave the perimeter.
Hunt, triage, and close cases from the shell, or pipe Sentry into CI. A typed API drives everything the UI can do.
Sentry ports with a maintained, open-source detection pack mapped to MITRE ATT&CK. Fork what fits, tune the rest, and your analysts inherit the community's best work the first time they boot.
LSASS dumping, Kerberoasting, token theft, and cloud key exfiltration — tuned to a sub-1% false-positive rate.
Pass-the-hash, remote service abuse, and east-west pivots traced across the identity and network graph.
Privilege escalation, role assumption, MFA fatigue, and impossible-travel correlated across every provider.
Anomalous egress, DNS tunneling, and bulk object reads from your buckets flagged the moment they spike.
Scheduled tasks, registry run-keys, and malicious OAuth grants surfaced before the attacker comes back.
PowerShell, certutil, and signed-binary abuse caught by behavior, not signature.
“We moved our detections into Sentry and started treating them like code — reviewed, tested against last quarter's logs, shipped in a PR. Our false-positive rate fell off a cliff, and we finally trust what pages us.”
“A credential-dump playbook isolated the host and killed the session in eleven seconds, then drafted the after-action while I was still reading the timeline. With our old SIEM that was a Monday-morning post-mortem.”
“One query against the whole lake replaced four CSV exports and a spreadsheet. I hunted across thirteen months of history before my coffee went cold, then turned the best hunt into a live rule.”
Per-gigabyte pricing punishes you for watching more of your environment. Sentry bills for the people running the SOC, not the logs they read.
For small teams standing up a real SOC.
For security teams working cases around the clock.
For regulated, multi-region, air-gapped operations.
Either. Most teams run Sentry as the primary platform — lake, detections, automation, and case management in one place. If you're mid-contract, point your existing pipelines at Sentry and use it as the detection-and-response layer on top, then migrate the lake when you're ready.
Your rules live in a git repo as YAML and Sigma. You test them against replayed historical logs in CI, review them in a pull request, and promote from staging to production with a merge. A bad rule is one git revert from gone — no clicking through a vendor console.
No. Sentry deploys single-tenant inside your own cloud, or fully air-gapped on-prem. Logs, cases, and forensic timelines stay in infrastructure you control and never co-mingle with another customer's. You can pin data residency by region.
The opposite. Sentry fuses correlated signals into a single case ranked by blast radius and confidence, so analysts work investigations instead of triaging raw alerts. Teams routinely see the volume reaching a human drop 85 to 94 percent after tuning.
Anything you already emit: OpenTelemetry over OTLP, syslog, HTTP, CloudTrail, Okta and Entra ID, Kubernetes audit logs, EDR feeds, and raw events from an S3 bucket you own. No proprietary agent is required to start.
Sentry is SOC 2 Type II and ISO 27001 certified, writes immutable audit logs of every analyst action, and maps each detection to MITRE ATT&CK so you can evidence coverage to assessors and your board.
Spin up the free tier in your own cloud, point a log source at it, and walk a real incident before lunch. No sales call, no proprietary agent, no data leaving your perimeter.
