Autonomous DevOps

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.

Capabilities

What Sentinel does

01

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.

02

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.

03

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.

04

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.

05

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.

06

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.

07

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.

08

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.

Sentinel FAQ

Sentinel - common questions

Sentinel is the autonomous DevOps product inside the Juniors AI workspace. It watches your AWS infrastructure continuously, diagnoses incidents with AI root-cause analysis, and acts through policy-gated automations (restart, redeploy, scale) so a small team can operate a large platform in minutes a day.
