Network Architecture

    Build a Network That Protects Client Data

    Properly designed and segmented networks are the foundation of data security. Protect your firm with architecture built for compliance and resilience.

    Security Starts at the Network Level

    A well-designed network is your first and most important line of defense against data breaches.

    Network Segmentation

    Isolate sensitive financial systems from general office traffic to contain threats and protect client data.

    Secure Remote Access

    Enterprise VPN and zero-trust access for staff working from home, client sites, or on the road.

    Managed Firewalls

    Next-generation firewall management with intrusion prevention, content filtering, and real-time threat blocking.

    Frequently Asked Questions

    What is network segmentation and why do accounting firms need it?

    Network segmentation divides your network into isolated zones — for example, separating the network segment that handles client tax data from the general office network and guest Wi-Fi. This limits the blast radius of a security incident and prevents lateral movement by attackers who might gain access to one segment.

    How do you secure remote access for staff working from home?

    We implement enterprise VPN solutions with split tunneling, device health verification, and multi-factor authentication. For firms adopting zero-trust architecture, we deploy solutions that verify every access request regardless of location, ensuring remote workers have the same security protections as in-office staff.

    Can you manage firewalls for multiple office locations?

    Yes. We provide centralized firewall management across all your locations with consistent security policies, unified logging, and site-to-site VPN connectivity. Changes can be deployed to all locations simultaneously, and our team monitors all firewalls 24/7 for threats.

    How does secure network design help with compliance?

    IRS Publication 4557 and SOC 2 both require appropriate network security controls. Proper segmentation, encrypted communications, access controls, and firewall management are all key requirements. Our network designs are built with compliance documentation in mind.

    What if our firm is moving to the cloud?

    We design hybrid network architectures that securely connect on-premises systems with cloud services like Microsoft 365, cloud-hosted practice management, and virtual desktops. Our cloud network security includes virtual firewalls, encrypted tunnels, and micro-segmentation to protect your data wherever it lives.
