Linux EDR

Linux EDR that acts — not just alerts

Watch is a Linux-native endpoint detection and response platform. Cortex AI classifies threats in under 8ms on the agent itself — no cloud call — and responds autonomously: banning IPs, killing processes, initiating lockdown. No human approval required.

What is Linux EDR?

Linux EDR (Endpoint Detection and Response) is a security discipline that continuously monitors Linux servers for threats — malicious processes, unauthorized network connections, brute-force attacks, cryptominers, privilege escalation — and responds to them in real time. Unlike traditional antivirus, EDR records rich telemetry, correlates events across time, and can take automated response actions.

Most Linux EDR tools detect and alert. Watch goes further: Cortex AI runs directly on each agent, classifies threats locally in under 8ms, and executes the response without waiting for a human or a cloud round-trip.

How Watch Linux EDR works

1. Agent deployment

One command installs the Watch agent on any Linux server in under 60 seconds. It connects outbound over WSS — no inbound firewall changes required. Supports Ubuntu, Debian, CentOS, RHEL, Fedora, and Arch.

2. Cortex AI on-agent classification

Cortex runs locally on each agent — not in the cloud. It monitors processes, network connections, file integrity, and system events continuously. When an anomaly is detected, Cortex classifies it in under 8ms using locally cached threat signatures and behavioral models.

3. Autonomous response

In Autopilot or Sovereign mode, Watch acts immediately on confirmed threats: banning source IPs, killing malicious processes, revoking compromised credentials, or initiating a full server lockdown. Every action is reversible and logged with cryptographic chain-of-custody.

4. Fleet immune memory

When a threat is confirmed on one server, Cortex Hive broadcasts the threat signature to every other agent in your fleet in real time. A cryptominer caught on one VPS instantly protects all your others — without you doing anything.

5. Override learning

When operators override an AI decision, that correction improves Cortex's behavior fleet-wide — automatically, without manual retraining. The more you use Watch, the smarter it gets about your specific environment.

Installs in under 60 seconds. Outbound-only connection. No inbound firewall changes.

Frequently asked questions

What is the difference between Watch and Wazuh for Linux EDR?
Wazuh is an open-source HIDS/XDR that detects and alerts — response actions require human review and custom scripting. Watch's Cortex AI responds autonomously: no scripting, no human required. Watch also runs without a self-hosted backend (Wazuh requires deploying indexer, server, and dashboard components), installs in 60 seconds versus Wazuh's multi-hour setup, and includes a built-in secret vault, compliance automation, and fleet immune memory that Wazuh lacks entirely.
Is Watch suitable for small teams or just enterprise?
Watch is designed for teams without dedicated security staff — the whole point is that Cortex AI acts when no human is available. The Developer plan ($39/month) covers 5 servers with full autonomous response. The Business plan ($149/month) covers 25 servers and adds compliance automation and fleet threat broadcasting. Enterprise and Empire tiers serve unlimited server fleets.
Does Watch Linux EDR require a kernel module or eBPF?
Watch's agent uses standard Linux APIs and does not require a kernel module or eBPF. This means it runs on any kernel version across all major distributions without compatibility concerns, and installs without rebooting.
How does Watch handle false positives?
All Watch response actions are reversible with one click. When an operator overrides a decision (marking an action as a false positive), that correction is propagated to Cortex fleet-wide — preventing the same false positive on other servers. In Watch and Assist modes, the AI suggests actions rather than acting; Autopilot mode can be scoped to specific action types to limit blast radius.
What threats does Watch Linux EDR detect?
Watch detects: brute-force SSH attacks, cryptomining processes, unauthorized process spawns, privilege escalation attempts, suspicious outbound connections, file integrity violations, rootkit indicators, unauthorized user account changes, and anomalous network behavior. Cortex Hive also broadcasts threat intelligence from across the fleet, so Watch detects novel threats seen on any customer's server — not just your own.
