Work model: hybrid from Warszawa (2-3 days per week from the office)
The project focuses on migrating the existing TrustSec implementation from RADIUS to a more resilient REST API–based integration with Cisco ISE to eliminate authentication instability across network switches. It involves automating REST API credential updates for all NADs, reconfiguring Catalyst switches for TrustSec over REST, and enabling enhanced profiling and access-session features. The goal is to increase platform reliability, improve 802.1X performance, and ensure consistent NAC operations in a complex enterprise network environment.
responsibilities :
Migrate the current TrustSec implementation from RADIUS to a REST API–based integration with Cisco ISE
Automate REST API credential updates across all Network Access Devices (NADs)
Reconfigure Catalyst switches to support TrustSec over REST, profiling over RADIUS, and access-session mac-move
Troubleshoot and optimize 802.1X, AAA, and TrustSec-related issues, including MTU impacts in SD-WAN environments
Collaborate with security and network teams to ensure stable NAC operations and high availability of the ISE platform
Develop scripts and automation to streamline configuration updates and support large-scale network changes
Perform validation, testing, and documentation of new configurations and migration steps
Provide expert-level guidance on Cisco ISE, TrustSec, and Catalyst switch best practices
