Next-Gen Firewall
Configuration & Management
Deploy, configure, and manage enterprise firewalls with zero-trust segmentation, WAF protection, and continuous rule optimisation across on-prem and cloud environments.
We don't just deploy firewalls — we design architectures, optimise rulesets, and build the operational capability for your team to manage them.

The Plaidnox Difference
Why Enablement Matters as Much as the Technology
Rulesets accumulate cruft and nobody audits them
Overly permissive rules are deployed as temporary fixes and never tightened
No change management process so rules proliferate without accountability
Logs are forwarded but nobody is reviewing or correlating them
Most firewall deployments degrade over time because the operational disciplines around them aren't maintained.
Building change management processes your team follows consistently
Training network engineers to audit and optimise rulesets independently
Documenting every rule with business justification and review dates
Establishing quarterly audit cycles so rulesets stay clean over time
The result is a firewall programme that gets stronger over time, not weaker — because your team owns and maintains it with the right processes in place.
What We Deploy
Firewall Capabilities
From next-gen firewalls to cloud WAFs — complete network security enablement.
Next-Gen Firewall Deployment
We deploy and configure next-generation firewalls with application-aware policies, threat prevention profiles, URL filtering, and SSL/TLS decryption — not just port-and-protocol rules that belong in a previous decade. Every deployment is designed around your network topology, traffic patterns, and business requirements. Rulesets are built collaboratively with your team, documented thoroughly, and validated with traffic analysis before cutover.
Network Segmentation & Micro-Segmentation
Flat networks give attackers free movement. We design and implement zone-based segmentation architectures that contain lateral movement and enforce least-privilege networking between trust zones. For more mature environments, we implement micro-segmentation using host-based enforcement or software-defined networking — restricting communication to only what is required between individual workloads, servers, and application tiers.
Web Application Firewall (WAF)
We deploy and tune WAF policies for OWASP Top 10 protection across web applications, APIs, and microservices. WAF rulesets are configured to block known attack patterns while minimising false positives that disrupt legitimate traffic. Tuning is done iteratively using real traffic data, and WAF logs are integrated with your SIEM for centralised visibility and correlation with network-level events.
Traffic Analysis & Visibility
You cannot secure what you cannot see. We enable deep packet inspection, SSL/TLS decryption at scale, application-layer visibility, and integration with threat intelligence feeds so your team has genuine insight into what is moving across your network. Dashboards are configured for both operational and executive audiences, and alerting thresholds are set to surface meaningful events without overwhelming your team.
Policy Management & Optimisation
Firewall rulesets accumulate cruft over time. Shadowed rules, redundant entries, overly permissive any-any rules, and rules with no hit counts all erode the security a firewall is supposed to provide. We conduct full rule lifecycle audits, identify and remove unnecessary rules, tighten overly broad policies, and document every change. The result is a cleaner, more defensible ruleset that your team can maintain with confidence.
Cloud Firewall & SASE Architecture
Cloud-native environments need cloud-native security. We design and deploy cloud firewall policies across AWS Network Firewall, Azure Firewall, and GCP Cloud NGFW — integrating with VPC/VNet security groups and network ACLs. For organisations with distributed workforces, we design and deploy SASE architectures combining ZTNA, SWG, CASB, and FWaaS into a unified, cloud-delivered security model.
Our Approach
Firewall Deployment & Enablement
From assessment to managed operations — zero downtime firewall enablement.
Network Discovery & Assessment
We start by mapping your existing network topology, firewall rules, traffic flows, NAT configurations, and VPN tunnels. We identify security gaps, compliance risks, overly permissive rules, and architectural weaknesses. For organisations with existing firewalls, we conduct a full rule audit and produce a prioritised findings report. For greenfield deployments, we document requirements and design constraints.
Architecture & Policy Design
We design segmentation zones, rule hierarchies, NAT policies, VPN configurations, and high-availability architectures aligned to your business requirements and compliance obligations. Policy designs are documented, reviewed with your team, and signed off before any deployment begins. Every design decision is explained so your team understands not just what is being deployed, but why.
Deployment & Migration
Firewall appliances, virtual firewalls, or cloud-native services are deployed and configured. For migration scenarios, we migrate existing rules to the new platform, validate connectivity, and cutover with zero downtime using parallel deployment or phased migration strategies. Every change is tested and rolled back if any connectivity issue is detected.
Integration & Validation
The firewall platform is integrated with your SIEM for log forwarding, your identity platform for user-based policy enforcement, and your SOC for alert routing. We run penetration tests against the firewall to validate that rules are enforced correctly and that the configuration is resistant to common bypass techniques. Integration testing confirms that every component works together as designed.
Managed Operations & Continuous Tuning
Ongoing rule optimisation, threat feed updates, performance monitoring, and policy change management ensure the firewall continues to perform as your network evolves. We provide quarterly rule audits, monthly performance reports, and change advisory support so your team can make informed decisions about policy changes. The goal is a firewall programme your team can own and operate with confidence.
