Firewall Implementation, Migration & Hardening
Your firewall is only as strong as its configuration. Altrixys designs, deploys, migrates and hardens firewalls so the rules on paper match the protection in practice — validated from an attacker’s perspective and delivered without disrupting operations.
What firewall implementation includes
Whether you are deploying your first next-generation firewall, migrating vendors, or cleaning up years of accumulated rules — every engagement ends with a tested, documented configuration.
Design & Implementation
Architecture, zoning and deployment of next-generation firewalls sized and configured for your actual traffic and risk profile.
Vendor Migration
Structured migration between platforms with rulebase translation, side-by-side validation and a zero-downtime cutover plan.
Rulebase Review & Cleanup
Removal of shadowed, obsolete and overly permissive rules — the quiet holes that accumulate over years of “temporary” changes.
Network Segmentation
Zone design and inter-VLAN policies so a compromised workstation cannot reach your critical systems directly.
VPN & Remote Access
Secure site-to-site and remote-access VPN with modern cryptography, MFA integration and least-privilege access policies.
Hardening & Baseline
Management-plane lockdown, logging, geo and threat-feed policies, and a documented best-practice baseline you can audit against.
Configured by people who break firewalls for a living
Attacker-validated rules
We test the perimeter we build. Every deployment is verified with authorized probing — not just a checkbox review.
Zero-disruption cutovers
Migrations planned around your business hours with rollback paths — following our zero-disruption principle.
Documentation that survives audits
Topology, rule intent and change history documented — ready for compliance reviews and future engineers.
Frequently asked questions about firewall implementation
How long does a firewall implementation take?
Most firewall implementation and migration projects run one to three weeks, depending on rule complexity and the number of sites. We agree a fixed scope and a zero-downtime cutover window before starting.
Do you work with our existing firewall vendor?
Yes. We are vendor-neutral and work across the major next-generation firewall platforms — whether you are deploying new hardware, migrating between vendors, or hardening what you already own.
What happens after the firewall is deployed?
You receive full documentation of the topology, rule intent and baseline, plus optional ongoing operation through our Managed Firewall service.
