Enterprise Networking & Security
Cisco ISE can improve network access control dramatically, but it also adds operational complexity. Sun Life Tech helps businesses implement, clean up, and support ISE in a way that remains understandable after go-live.

Use the jump links below to move through planning, design, security, vendor support, and next-step topics.
We can review the current environment, the risk, and the operational impact before you commit to a migration, firewall replacement, or managed support plan.
Security delivery
This support sits inside the same documented risk, access, supplier, and continuity framework used across Sun Life Tech services.
Sun Life Tech self-declares conformity of its Information Security Management System with ISO/IEC 27001:2022 within its defined scope. Our ISMS addresses risk management, controlled access, supplier oversight, incident response, continuity planning, internal review, and continual improvement.
First-party declaration; not accredited third-party certification.
The platform is most useful when the business wants more confidence about who and what is connecting to the network, how that access is segmented, and how administrative access is controlled.
Move away from broad shared trust where the environment and support model justify it.
Understand what is attaching to the network and apply better policy to different device types.
Keep guest onboarding separate and supportable instead of mixing it with internal access logic.
Improve accountability and role-based access for network administration.
A good ISE deployment documents onboarding flows, exceptions, certificates, identity stores, and fallback behavior before the first production complaint arrives.
Many ISE frustrations come from partial documentation, unclear exception handling, and too many access-policy edge cases added after go-live. The technical platform may be working, but the team no longer trusts how to change it safely.
That is why cleanup and supportability are as important as initial deployment. The environment should remain understandable to the next engineer and to internal teams who need to support onboarding, guest access, and troubleshooting.
