Enterprise Networking & Security
Fortinet can be a strong fit when the business needs practical firewall visibility, SD-WAN control, and centralized management without unnecessary complexity. Sun Life Tech helps keep those environments readable and supportable.
Vendor-specific expertise • Clear designs • Practical operational support
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.
Vendor-specific work is useful when the platform is already in place, when a migration is under consideration, or when policy and operational discipline have drifted over time.
A lot of businesses do not need a brand-new platform. They need a cleaner design, a tighter rulebase, a more defensible remote access model, or a realistic upgrade path. Fortinet Firewall Services work is often about stabilizing what already exists before the next outage, security incident, or renewal cycle forces a rushed decision.
Sun Life Tech approaches vendor-specific work from an operations perspective. We review the business dependency, the current topology, the access model, the monitoring gaps, and the support burden before recommending changes. That keeps the project tied to uptime, security, and maintainability instead of feature lists alone.
Interface planning, policy creation, VPN setup, HA, and staged cutover work.
Centralized policy management where it adds value and supports clean change control.
Improve visibility and reporting so the environment is not operating blind between incidents.
Remote access, site-to-site tunnels, path selection, and branch behavior aligned to the business dependency.
Use Fabric integrations where they improve visibility and response without creating unowned complexity.
Policy review, object cleanup, stale tunnel removal, performance tuning, and documentation.
The platform has to be supportable after deployment. That means clean documentation, clear ownership, logging that someone actually reviews, and a realistic escalation path when something breaks.
Many vendor deployments drift because the original design never became an operating standard. Rules pile up, firmware lags, VPN exceptions multiply, and the next engineer has to reverse-engineer the intent from the config itself.
Logs are useful when someone actually reviews them with a cadence and knows what needs escalation.
HA is only valuable when failover behavior, firmware parity, and upstream/downstream dependencies are tested.
Fortinet environments benefit from version discipline, especially when Fabric, FortiManager, and analyzer components are tied together.
Fortinet is often chosen for distributed sites. Consistency across policies and branch behavior matters more than feature availability alone.
The platform matters, but the cutover discipline matters more. Good migrations are designed around business hours, rollback paths, dependency mapping, and communication before the change window starts.
Fortinet migrations should account for policy order, NAT behavior, VPN peers, certificates, inspection scope, and branch dependencies before the change window begins.
Where SD-WAN is in scope, the business also needs a path validation and failback plan. Application behavior and voice stability should be validated after cutover, not assumed.
Confirm hardware, licensing, interfaces, dependencies, VPN peers, and policy expectations before planning changes.
Map current state against target state so there is a documented delta, not just a copied configuration.
Schedule the change window, define validation checkpoints, and keep a rollback plan ready before touching production.
Capture the final design, backup the config, and review logs and operational behavior after the migration.
These engagements often touch mixed environments, not single-vendor labs. The goal is a network that can be supported over time, not loyalty to a badge.
