Enterprise Networking & Security
A firewall should not drift into a black box after deployment. Sun Life Tech provides ongoing firewall monitoring, cleanup, firmware planning, and reporting so the edge stays secure and understandable over time.

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.
Most firewall environments become harder to support over time because nobody owns the recurring work after the install or migration closes out.
The firewall may be stable on day one, but stability fades if firmware updates are skipped, policies change without review, HA is never retested, and backups are not validated. Managed firewall service is the discipline that keeps the design supportable after the project team is gone.
For many small and midsized businesses, the goal is not to outsource every network decision. The goal is to keep rule quality, visibility, and lifecycle hygiene from slipping until the next outage or renewal crisis appears.
Watch tunnel health, interface behavior, HA status, and priority security events with a repeatable escalation path.
Track versions, support status, compatibility concerns, and maintenance windows before the environment drifts too far behind.
Retain current and historical configs so a hardware failure or bad change does not become a rebuild-from-memory event.
Changes accumulate. Managed service creates a cadence to review them before they turn into support debt.
Identify stale, duplicate, broad, or undocumented rules and track what can be tightened safely.
Handle approved policy changes in a way that preserves documentation and rollback clarity.
Summarize notable events, risk items, firmware status, rule hygiene, and recommended next actions in plain English.
Work with ISPs, software vendors, VoIP providers, and platform support when the firewall sits in the middle of the issue.
During an outage or suspicious event, known-good documentation and recurring familiarity with the firewall matter more than raw feature count.
