Damage Control You Build in Advance
Most firms run one flat network where every device can see every other device. That works fine until the day it doesn't, and then it works against you.
Segmentation
Client data lives on its own segment, away from the guest Wi-Fi, the conference room TV, and whatever the printer thinks it's doing.
Remote Access With Checks
VPN and zero-trust access that verify the machine before it reaches anything, so a home laptop with three years of missed patches doesn't get a seat at the table.
Managed Firewalls
Rules written for your firm, firmware kept current, threat feeds applied. Somebody owns the box, which is more than most firms can say.
See Your Entire Network at a Glance
Every segment, every connection, every device, with health and policy state alongside it. The inventory alone usually earns the exercise. Almost every firm we map turns up something on the network that nobody present can account for.

The Pieces We Design and Run
Firewalls, zones, remote access, wireless, and the cloud side of it, all under one set of rules rather than five.
Zone Design
Client data, staff operations, guest access, and VoIP traffic on separate zones, with deliberate rules about what crosses between them.
VPN and Zero Trust
Encrypted access with device health checks, so getting on the network means proving the machine is in reasonable shape first.
Firewall Management
Rule changes, firmware updates, and log review handled, with a change history you can hand to an auditor.
Cloud Connectivity
Virtual firewalls and encrypted tunnels for cloud workloads, which now hold as much client data as the server closet ever did.
Multi-Site Architecture
Site-to-site VPN and SD-WAN with the same policy at every office, including the one with two people in it.
Wireless Done Properly
WPA3, client isolation, and a guest network that reaches the internet and nothing else on your network.
Who It's For
Firms whose network grew one device at a time and has never been drawn on paper.
Multi-Office CPA Firms
Branch offices connected under one policy instead of three different setups from three different installers.
Remote & Hybrid Teams
Access from home and from client sites that's fast enough to use and checked enough to trust.
Growing Practices
Architecture that survives the next ten hires and the next office without a rebuild.
Block all inbound RDP
Any → All Segments
Allow VPN tunnel (Branch Office)
192.168.2.0/24 → Client Data Zone
Restrict guest to internet only
Guest VLAN → Internet
Allow VoIP SIP traffic
VoIP Zone → SIP Provider
Block known malicious IPs
Threat Feed → All
Somebody Owns the Firewall
We manage the rules, read the logs, and keep firmware current. In plenty of small firms the firewall was configured once by whoever installed the internet and hasn't been touched since. That's a fine arrangement right up until a vulnerability gets published for that exact model.
- Custom rules for your practice
- Threat intelligence integration
- Multi-site policy management
Frequently Asked Questions
What is network segmentation, and why does it matter here?
Segmentation splits the network into zones that can't freely reach each other, so the machine holding client tax data isn't sitting on the same flat network as the guest Wi-Fi and the conference room TV. When something does get in, segmentation decides whether you're cleaning one laptop or the entire firm.
How do you handle staff working from home?
VPN with device health checks and MFA, or zero-trust access that verifies each request no matter where it comes from. The check on the device is the important half. A personal laptop the whole family uses shouldn't get the same access as a firm-managed machine.
Can you manage firewalls across several offices?
Yes. One console, the same rules everywhere, site-to-site VPN between locations, and unified logging. Policy changes go out to every office at once, which beats the alternative of discovering in year three that the branch firewall was never configured past the default.
How does network design help with compliance?
IRS Publication 4557 and SOC 2 both expect network controls: segmentation, encrypted communication, restricted access, managed firewalls. We design with the documentation in mind, so what you built and what you can prove you built are the same thing.
What if we're moving everything to the cloud?
Then the network gets smaller and identity gets more important, but it doesn't disappear. We build hybrid designs connecting on-premises systems to Microsoft 365, hosted practice management, and virtual desktops, with virtual firewalls and encrypted tunnels around the cloud side.
