- Senior
- Not mapped
- You've done network engineering and want to specialise into security
- You enjoy segmentation, firewalls and SSE / SASE work
- You're prepared to deal with both network and security politics
- You're patient with change-control and approval cycles
- You haven't done meaningful networking yet
- You expect to be doing SOC or detection work, this isn't that
- You'd resent the dependence on vendor roadmaps
What "doing well" looks like in the seat
- Your firewall changes go in cleanly and roll back cleanly
- Your segmentation designs survive audit and incident review
- You can defend an SSE choice in writing
- Both network and security teams trust your judgement
A control that blocks traffic may also block a critical service. Check ownership across networking and security, exception review and recovery of failed changes.
