Enterprise Networking & Security
A network security assessment should do more than generate a long list of issues. Sun Life Tech focuses on the risks that create real exposure, support burden, and business interruption.

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.
The goal is not to overwhelm the client with every possible issue. It is to identify the weaknesses most likely to lead to compromise, downtime, or painful support events.
Policy quality, inter-VLAN controls, published services, and hidden broad-access patterns.
VPN exposure, MFA use, user scope, split tunneling, and supportability.
Guest isolation, WPA settings, onboarding flow, and staff/client separation.
Hardware age, software support status, and known upgrade debt.
A finding is more important when it affects a critical workflow, expands blast radius, or increases the chance that a simple incident becomes a multi-day outage.
| Review area | What we look for | Why it matters |
|---|---|---|
| Segmentation | Flat networks, broad east-west access, unmanaged guest paths | Limits or expands blast radius during compromise |
| Firewall policy | Stale rules, broad objects, undocumented access | Creates hidden exposure and troubleshooting pain |
| Remote access | Weak MFA, poor route design, vendor access sprawl | Raises account-takeover and persistence risk |
| Lifecycle | Unsupported firmware or aging hardware | Increases stability and security risk while reducing support options |
A strong assessment gives the business a realistic sequence of next steps instead of leaving leadership to decode the findings alone.
