New Relic At its core, New Relic is an All-in-One Observability Platform. It doesn’t just collect data; it correlates it. By gathering "MELT" data (Metrics, Events, Logs, and Traces), it provides a single source of truth for your entire software stack—from the browser your customer is using down to the container running your code.

Key Features You Should Know APM 360: Gives you a holistic view of your application’s health, including golden signals like latency, traffic, and error rates.

Security RX: This is the "Sec" in DevSecOps. It provides runtime vulnerability management, telling you which libraries are actually vulnerable while they are running.

Infrastructure Monitoring: Deep visibility into Kubernetes, AWS, Azure, and on-premise hosts.

AIOps: Uses machine learning to detect anomalies and group related alerts, preventing the dreaded "alert fatigue."

How It Fits into DevSecOps New Relic acts as the continuous feedback loop. In a traditional DevOps flow, you plan, build, and deploy. In DevSecOps, you need to know immediately if a deployment introduced a security flaw or a performance lag.

New Relic integrates with CI/CD tools (like GitHub Actions) to mark deployments. If your error rate spikes after a "git push," New Relic points to the exact line of code responsible. With Security RX, it shifts security "right" by monitoring production environments for real-time exploits.
