Firepower and ISE integration - successful deployments?

Hey everyone, newbie here 👋 I’ve been diving into our company’s security stack and keep hearing about integrating Cisco Firepower with ISE for better network access control. It sounds really powerful, especially for tying firewall policies to user identities instead of just IP addresses.

We’re a mid-sized SaaS company, and we’re looking to tighten up security as we grow. I’ve read the docs, but I’m curious about real-world experiences. Has anyone here actually rolled this out successfully?

What was the biggest hurdle you faced during deployment? And maybe more importantly, once it’s up, does it actually make day-to-day management easier for the team? I’m trying to build a case for this project, and practical insights would be super helpful.
