Firewall Deployment & Hardening
From initial deployment to ongoing rule optimization, we design and harden firewall architectures purpose-built for critical infrastructure networks, including IT/OT boundary enforcement, zone segmentation, and VPN hardening across headquarters and remote substations.
How we approach every firewall engagement
Every engagement follows a proven, repeatable methodology, adapted to the unique topology and compliance posture of your organization.
Discovery & Audit
We inventory every firewall, switch, and routing device across your environment. Existing rule sets are exported, analyzed, and benchmarked against best practices and NERC CIP requirements.
Policy Design
Our engineers design a clean, least-privilege policy framework tailored to your organization's traffic flows, separating IT, OT, guest, and management zones with purpose-built rule sets.
Deployment / Migration
We handle the full hardware deployment or migration, racking, cabling, configuration, and cutover, with planned maintenance windows and rollback procedures to ensure zero unplanned downtime.
Hardening & Optimization
Post-deployment, we lock down management interfaces, enable advanced threat prevention features, eliminate shadow rules, and tune policies based on real traffic analysis.
Monitoring Handoff
Every firewall is integrated into TITAN for centralized log ingestion, alerting, and real-time visibility. Your SOC team gets dashboards purpose-built for critical infrastructure environments.
Ongoing Support
We don't disappear after deployment. SkyHelm provides ongoing rule change management, quarterly policy reviews, and rapid-response support for your firewall infrastructure.
What we deliver
Next-Gen Firewall Deployment
Full lifecycle deployment of NGFW platforms with application-aware inspection, SSL decryption, and integrated threat intelligence feeds.
Policy Review & Cleanup
Elimination of duplicate, shadowed, and overly permissive rules. We turn sprawling rule sets into clean, auditable policies.
Zone Architecture Design
Purpose-built security zones for IT, OT, DMZ, guest, and management traffic, each with tailored inspection and logging policies.
IT/OT Boundary Enforcement
Strict enforcement of the electronic security perimeter between corporate IT and operational technology networks, satisfying NERC CIP requirements.
VPN Configuration
Site-to-site and remote access VPN tunnels configured with modern encryption, certificate-based authentication, and split-tunnel policies.
Rule Optimization
Traffic-flow analysis to identify unused rules, optimize hit counts, and reorder policies for maximum throughput without sacrificing security.
Multi-Site Rollout
Standardized templates and automated provisioning for deploying consistent firewall policies across headquarters, substations, and field offices.
TITAN Integration
Every deployment connects to TITAN for centralized syslog, firewall event correlation, and automated alerting, giving you ongoing visibility from day one.
The right team for your firewall project
Dozens of Deployments
We've deployed and hardened firewalls for cooperatives of every size, from 5,000 meters to 500,000. We know the traffic patterns, the compliance requirements, and the budget realities.
Vendor-Agnostic Expertise
Whatever next-gen firewall platform fits best, we recommend and deploy what's right for your environment, not what earns us the biggest margin. Our engineers hold certifications across all major platforms.
We Don't Leave Until It's Working
This isn't a consulting engagement that ends with a PDF. Our engineers stay on-site or on-call until every rule is tested, every zone is validated, and your team is trained.
Built-In Ongoing Visibility
Every firewall project integrates with TITAN, our critical infrastructure security platform. You get real-time dashboards, automated alerting, and 24/7 SOC monitoring from the moment we hand off.
