Sentinel
See everything. Diagnose anything. Heal automatically.
Sentinel is an AI-driven DevOps control plane for your AWS cloud. A thin agent runs inside your own account and dials out to the control plane (no inbound access, no VPN, least-privilege IAM), and every metric, incident, and audit record persists in a PostgreSQL database in your own cloud. A continuous watch loop scans ECS, RDS, ALB, and ElastiCache around the clock; an AI root-cause engine correlates metrics, logs, and recent deploys into a plain-English diagnosis with a P0-P3 severity; and policy-gated, confidence-scored automations restart, redeploy, or scale the affected service. Cost rightsizing, WAF and security-group drift insights, and a scheduled-jobs health view round it out - so one engineer can operate the whole platform in minutes a day.
What Sentinel does
An agent in your own cloud
A thin agent runs inside your own AWS account and dials out to the control plane over an enrollment token. No inbound access, no VPN, least-privilege IAM. Telemetry, incidents, and the audit trail persist in a PostgreSQL database in your own cloud, never on Juniors AI servers.
One pane of glass
Unified monitoring across your services: ECS CPU and memory with scaling, ALB p99 latency and 5xx errors, RDS load and free storage, and ElastiCache health, all in one place. No more tab-hopping between half a dozen consoles.
Continuous watch loop
Sentinel scans your infrastructure every few minutes, around the clock. Live metrics are compared against your thresholds, and an incident opens the moment a signal breaches - while routine autoscaling noise is filtered out so only real, paging incidents surface.
AI root-cause analysis
When a signal breaches, the RCA engine pulls the relevant metrics, logs, and recent deploys and correlates them into a plain-English diagnosis: a P0-P3 severity, a confidence score, the likely root cause, a recommended action, and any attack indicators. With no LLM configured it falls back to an actionable rule-based assessment, so an incident is never blocked.
Policy-gated self-healing
Guarded fixes run automatically when you allow them: restart a crashed service, redeploy a bad release, scale a saturated one. Remediation only fires above a confidence threshold and inside a hard capacity clamp, every action is audit-logged, and anything outside policy waits for a human instead. Auto-remediation ships off by default.
Cost and rightsizing
Month-to-date spend, top services by cost, Savings Plan opportunities, and rightsizing recommendations - so capacity stays matched to demand without overpaying.
Security and drift insights
Watch attacks being blocked at the edge by your WAF, catch security groups that have drifted open to 0.0.0.0/0, and review a threat snapshot of the countries, IPs, and paths under fire - alongside any security incidents Sentinel has opened.
Slack alerts and a full audit trail
Incidents page Slack with a rich Block Kit diagnosis, routed by severity so a P0 is loud and a P3 stays quiet - with a global mute and a fail-safe fleet pause when you need them. Every remediation, scaling action, and infrastructure change is written to a tamper-evident audit log.
