Network Security & Firewalls
Lock down your network without slowing down your team. We design, deploy, and manage firewalls, VPNs, content filtering, and zero-trust controls for small businesses in Oak Brook and the Chicago suburbs.
What We Secure
Next-Gen Firewalls (NGFW)
Application-aware rules, IPS/IDS, geo-IP, and threat feeds tuned for your environment and bandwidth.
VPN & Remote Access
Site-to-site and user VPNs with MFA, split-tunnel policies, and device posture checks for safe remote work.
Zero-Trust Segmentation
VLANs, ACLs, and policy-based access so contractors, IoT, and guests stay isolated from core systems.
DNS & Web Filtering
Block malicious domains, phishing, and risky categories while keeping productivity apps accessible.
Secure Wi-Fi Edge
WPA2/3, 802.1X/RADIUS, and guest networks integrated with firewall policies and content filtering.
Monitoring & Response
Alerting, firmware lifecycle, config backups, and incident response with root-cause follow-up.
Common Solutions
Ransomware Guardrails
Block known bad IPs/domains, restrict lateral movement, and enforce least-privilege access.
Compliance-Ready Controls
Logging, retention, and segmentation that support HIPAA, PCI-DSS, and CMMC requirements.
Guest & Contractor Isolation
Captive portals and VLANs so guests stay online — and off your business network.
Branch & Warehouse Connectivity
Secure site-to-site links with QoS for VoIP and scanners — stable and predictable.

How We Work
Review your current topology, rules, internet circuits, and risks; define goals and compliance needs.
Create a segmentation and rule plan, then pilot with a rollback path to avoid outages.
Cut over during a maintenance window, document everything, and monitor/iterate with reports.

FAQs
What firewall vendors do you support?
We commonly manage SMB-friendly NGFWs and will work with your preferred vendor if you already have one in place.
Can you segment IoT devices and cameras?
Yes — we isolate IoT/CCTV on separate VLANs with limited access, while keeping management reachable.
Will new rules interrupt our business apps?
We stage changes, test, and monitor to ensure critical applications and VoIP keep working smoothly.
