Enterprise Networking & Security
Switching and routing decisions shape stability, security, and support burden for years. Sun Life Tech helps businesses design, refresh, document, and migrate network infrastructure with fewer surprises.

Quick navigation
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.
Core, distribution, and access layers do not have to be overbuilt. They do have to be understandable and supportable.
Build predictable upstream paths, clean routing boundaries, and sensible redundancy where business impact justifies it.
Use consistent port roles, PoE expectations, uplink design, and AP/device segmentation at the edge.
Review trunks, spanning-tree assumptions, default gateways, SVIs, and routing clarity before changing production paths.
Support VoIP and real-time traffic with policies that reflect actual business behavior instead of default assumptions.
Internet failover and branch consistency only help when the routing, firewall, and operational testing are aligned.
Many Florida businesses have enough dependence on cloud apps, phones, or remote access that a single internet circuit is now a genuine operational risk. That does not mean every site needs a full SD-WAN redesign. It means the business should understand how outages are handled, how failover behaves, and whether the branch can keep operating when the primary path disappears.
WAN work is also about predictability. Branch sites, medical offices, construction trailers, engineering teams, and multi-location operations all benefit when internet, firewall, switching, and wireless expectations follow the same playbook instead of being reinvented site by site.
Plan edge behavior, path preferences, and validation testing before trusting the design during a real outage.
Choose static routing, OSPF, BGP, or SD-WAN behavior based on the actual branch complexity and support model.
Capture the site pattern so each new office or refresh does not become a custom project.
Good segmentation reduces blast radius and makes troubleshooting easier. Good QoS improves voice and real-time traffic without becoming a mystery policy nobody wants to touch.
