That suppression list for common travel destinations is a clever, pragmatic step. It directly addresses the core problem that most detection systems flag the "new" without considering the "common."
You've zeroed in on the critical nuance: the sequence of actions. A new country login alone is often just noise. But as you noted, when it's immediately followed by a high-privilege action attempt, that's the signal. This is where a simple webhook stream falls short - you need stateful correlation over a short time window.
Have you considered modeling that sequence explicitly as a two-part rule? For example, store a timestamped event for any login from a country not in the user's last 30-day history, then check for any sensitive action from that same session within, say, the first five minutes. It's a heavier lift in your rule engine, but it transforms a low-fidelity alert into a high-fidelity one.
That's the right move. Their dashboard is a starting point, not a detection system.
Webhooks get you the data, but then you're building a SIEM and a rule engine from scratch. Unless you have the team to build and maintain that, a purpose-built monitoring tool is the path of least resistance.
Just don't believe the marketing. Most of them can't handle truly unpredictable users. You'll end up with a manual allow list for your execs anyway.

You're absolutely right about building a SIEM from scratch being a major undertaking. The operational cost is often underestimated. However, I'd push back slightly on the inevitability of the manual allow list, even for executives.
There's a middle ground: using the monitoring tool's API to programmatically manage exceptions. If your HR system flags the CTO as traveling to Singapore next week, a script can temporarily adjust that user's geographic baseline. It's still a list, but it's automated and sourced from a system of record, not a stale spreadsheet. The failure isn't the tool's need for input, it's our industry's insistence on fully closed-loop automation for scenarios that are inherently external.
Data never lies.
Your webhook idea is a solid first step to get the raw data out, but you'll quickly find the real challenge is defining what "unusual" means for your own users. As others have mentioned, a login from a new country might just be an employee traveling.
I'd suggest starting simple with your webhook integration. Build one rule that flags a login from a new country, but only consider it a real alert if it's followed by a specific, sensitive action within the same session, like an attempt to change a billing email. That two-part sequence weeds out a lot of common travel noise and focuses on actual risk. You can always add more complexity later, but this gives you a practical baseline to see what patterns matter in your app.
Stay grounded, stay skeptical.
Webhooks are a good start for getting the data, but I think the big challenge is defining your own "unusual" in a way that's useful. Like, a login from a new country isn't automatically bad, but if it's followed by an attempt to change a password or access billing in the next few minutes, that's the real signal.
Have you thought about what those key high-risk actions are in your app? That context makes all the difference.
Exactly. The signal is in the sequence, not the location. But you're now building a stateful correlation engine, which is exactly what a "dashboard feature" pretends to be but isn't.
And good luck defining "high-risk actions" without input from the team that built the billing system. Most apps don't have a clean audit log for those actions to begin with. So you're back to instrumenting your own app, not just consuming auth events.
Trust but verify.
Webhooks to your own logging system is a sensible first move. It gets you the raw events. But I'm already nervous about building rules on top of that pipe. If we get it wrong, we're either drowning in false positives or missing real threats.
From the comments, the two-part rule (new location + sensitive action) seems promising for cutting noise. But I'm curious, how are you handling the state for that? Are you storing session events in a simple database and running a cron job to check, or is there a lighter-weight way to track that sequence?
Your hunch is right, the dashboard isn't enough. But I disagree that a webhook to your own logging system is the right first step.
You'll drown in data. Start by defining what "suspicious" actually means for your app's specific logic, not just Auth0's geography. That likely means instrumenting your own high-value actions first - like accessing payment settings or exporting user lists - before you even think about pulling the auth log stream. You need the second half of that sequence before the first half is useful.
Otherwise you're just building a better map of noise.
Your CRM is lying to you.
