I recently purchased a new server, and backup system from Dominant Systems and am very pleased with the experience. Their technicians were attentive to every detail, understanding that it’s not just a machine, but the heart of our business, and assuring that the transition was seamless with little, if any, disruption to my operations. They impressed me as people passionate about what they do, not just performing a task.
Firewalls & Network Security Appliances
Firewall and network security appliances help control traffic, restrict unauthorized access, and protect the systems your organization relies on. Dominant Systems selects, installs, configures, monitors, and supports business firewalls for organizations across the Greater Ann Arbor Area. We bring practical security expertise and responsive human support to every engagement.

Where Business Network Security Breaks Down
A firewall cannot protect your organization effectively when its configuration no longer reflects your users, applications, locations, and current threats. Rapid technology changes can leave outdated rules and neglected firmware in place long after business requirements have shifted. These gaps can increase exposure, disrupt legitimate traffic, and make incidents harder to investigate.
Outdated Firewall Rules
Old or overly broad rules can expose services that no longer need external access. Without periodic review, exceptions accumulate and weaken network controls.
Unmonitored Security Events
A security appliance can generate valuable alerts, but those alerts need knowledgeable review. Unaddressed activity can allow suspicious behavior to continue unnoticed.
Configuration Errors
Incorrect policies can block employees, interrupt applications, or permit unnecessary traffic. Careful configuration management and testing practices
Aging Network Hardware
Older appliances may lack the performance or security capabilities required by a growing organization. Capacity constraints can also create bottlenecks and unreliable connections.
What Effective Firewall Management Looks Like
Strong network protection begins with controls designed around how your organization actually operates. We connect appliance selection, secure configuration, monitoring, maintenance, and support instead of treating installation as a one-time task. This approach gives your team clearer visibility and a more dependable security foundation.
Firewall & Network Security Appliance FAQs
How do I know whether my business needs a new firewall?
A replacement may be appropriate when an appliance is aging, no longer supported, creating performance bottlenecks, or missing required security capabilities. We can assess your current device, configuration, traffic demands, and network design. Our recommendation considers both present needs and expected growth.
Do you install and configure business firewalls?
Yes, Dominant Systems sells, installs, configures, monitors, and supports business firewall appliances. We can handle a new deployment, replacement, security hardening project, or troubleshooting engagement. Qualifying firewall installations may also be available as fixed-price projects after the scope is reviewed.
Can you support our existing firewall?
Support depends on the appliance, its condition, licensing, and the availability of vendor updates. We begin by reviewing the device, configuration, firmware, and current network requirements. If continued support is not practical, we can recommend an appropriate replacement path without relying on a single manufacturer.
How long does firewall installation take?
The schedule depends on network complexity, internet connections, remote access requirements, and the number of security policies that must be migrated. We review those details before defining the project plan and expected timing. Testing and documentation are included in the process so the transition is handled carefully.
Can firewall services support regulatory or security framework initiatives?
Firewall controls can support broader efforts involving HIPAA, PCI, NIST, CMMC, HITRUST, or SOC 2 Type 2 requirements. The appropriate configuration depends on your systems, data, risk profile, and obligations. We provide technical assistance, but no single appliance or configuration guarantees compliance.
Do you provide firewall monitoring after installation?
Yes, ongoing monitoring and support can be included through an appropriate managed service arrangement. Dominant Systems offers CompleteCARE managed IT services and SecureCARE managed security services with selectable coverage. We can also discuss project-based assistance when ongoing management is not required.
