Firewall Installation and Rule-Set Implementation.
Firewall installation with rule-set implementation per your security policy
Part of Network & Security Support. Last reviewed October 2026.
Quick answer
What is Firewall Installation and Rule-Set Implementation?
Firewall installation with rule-set implementation is the physical deployment of a next-generation firewall and the translation of your written security policy into configured zones, rules, NAT, and VPN tunnels. Deploris engineers install the appliance, implement the rules your security team approves, test traffic, and hand over a saved configuration and verification results.
WHAT THE WORK COVERS
What Firewall Installation and Rule-Set Implementation includes.
- 01Appliance rack mounting, power, and interface cabling for WAN, LAN, DMZ, and out-of-band management
- 02Zone and interface configuration, address and service objects, and rule ordering that follows your approved policy document
- 03Source and destination NAT, static routes or dynamic routing, and policy-based forwarding where the design requires it
- 04Site-to-site IPsec and remote access VPN configuration with phase 1 and phase 2 parameters matched to the far end
- 05Activation of IPS, antivirus, URL filtering, and decryption profiles as defined in your policy, with logging pointed to your SIEM or syslog collector
- 06High-availability pair setup (active/passive or active/active) with failover and failback testing
- 07Cutover execution with a documented rollback plan, plus a rule-by-rule verification using test traffic and hit counters
HOW WE DELIVER IT
How it is delivered.
- 1
Receive the policy and design
We review your rule matrix, object naming standards, NAT plan, and VPN peers with your security team, and list open questions in writing before staging begins.
- 2
Stage the firewall
The appliance is upgraded to the agreed software release, licensed, configured offline, and tested on a bench so the cutover contains as few unknowns as possible.
- 3
Install and cut over
During the approved window an engineer installs the unit, moves interfaces from the old firewall, and keeps the rollback path ready until traffic is confirmed.
- 4
Verify and document
We test each rule and tunnel with real traffic, check logs for unexpected denies, save the configuration, and deliver the verification record and closeout report.
INPUTS AND OUTPUTS
What you provide and what you receive.
You provide
- A written security policy or rule matrix approved by your security owner
- Firewall hardware, licenses, and the software release you want deployed
- VPN peer details, certificates or pre-shared key handling instructions, and ISP circuit information
- An approved change window with a named contact who can authorize rollback
- Access to your logging, SIEM, or central management platform for integration
You receive
- An installed firewall with the approved policy implemented
- An exported configuration backup and the software version recorded
- A rule verification sheet showing the test traffic used and the result for each rule
- VPN tunnel status evidence and HA failover test results
- A closeout report with photos of the cabling and a list of any deviations from the policy
WHEN IT FITS
When this is the right deliverable.
You are replacing an aging perimeter firewall pair and need the existing rule base migrated, cleaned up by your team, and cut over inside a short maintenance window.
You are rolling out the same firewall model and policy to many branch locations managed through a central console.
Your security team has written the policy but has no staff on site, and you need an engineer to implement it exactly and record what was tested.
