PrivateNexus doesn't replace your existing monitoring stack — it reads from it, so you get one place to check instead of switching between tools.
The Alerts view gives you a query-able feed of what's actually been firing, correlated against the services you have registered — not a separate dashboard you have to context-switch to when something's wrong.
Alerts and metrics are the signal; Security Lockdown Mode is what can act on it automatically at the Soft and Hard tiers. The two are connected but distinct — Alerts is where you look to understand what's happening, Lockdown Mode is what responds to it.
