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.
Recurring slowness, random disconnects, WiFi complaints, tunnel drops, and “we are not sure why the network behaves that way” are typical starting points.
Look at edge stability, tunnel behavior, support status, and obvious policy drift.
Review uplinks, VLAN design, AP placement assumptions, and common access-layer trouble spots.
Identify aging hardware, unsupported versions, and deferred updates that add risk.
Find out what the business cannot explain today and what that uncertainty costs during troubleshooting.
A health check is most valuable when it separates small cleanup work from bigger architectural issues and lifecycle problems.
