The Unmanaged Firewall Problem
Most businesses have a firewall. Far fewer have a firewall that's actively managed. A firewall installed and left alone quickly becomes a false sense of security: rules accumulate without review, firmware falls behind, policy exceptions made for temporary purposes become permanent, and nobody is watching what the device is actually seeing.
A firewall is only as effective as its configuration and the team maintaining it. STACK manages your hardware firewall as a live security control, not a set-it-and-forget-it appliance. That means current firmware, clean rule sets, continuous monitoring, and policies that reflect how your business actually operates today.
What Managed Firewall Includes
Managed firewall services cover the full lifecycle of your firewall, from initial configuration and ongoing policy administration to firmware management, log monitoring, and compliance reporting. STACK handles the technical work so your team doesn't need to carry the expertise in-house.
Whether you have an existing firewall that needs better oversight or you're evaluating new hardware, STACK can manage the device, the policy, and the ongoing monitoring from a single managed engagement.

What STACK Manages
Managed firewall is an ongoing service, not a one-time configuration. Every component of your firewall's effectiveness requires regular attention.
Policy Administration
Firewall rules are reviewed, maintained, and updated to reflect your current environment. Outdated rules are removed, temporary exceptions are tracked, and new policies are implemented with proper change management.
Firmware Management
Firewall firmware is kept current with security patches and updates applied on a tested schedule, closing known vulnerabilities before they can be exploited.
Log Monitoring
Firewall logs are monitored for anomalous traffic, blocked connection attempts, and policy violations. Suspicious patterns trigger investigation rather than getting lost in unreviewed logs.
Threat Detection
Intrusion prevention, malicious traffic blocking, and geo-based filtering are configured and maintained to stop known threats at the network perimeter before they reach internal systems.
Compliance Reporting
Firewall configuration reviews, rule audits, and log reports support compliance requirements for CMMC, HIPAA, PCI DSS, and other frameworks that require documented network security controls.
Network Segmentation
VLANs and zone-based policies isolate sensitive systems, guest networks, and operational technology from the rest of your environment, limiting the blast radius if any segment is compromised.
Managing Your Existing Firewall
If you already have a hardware firewall in place, STACK can take over management without replacing your hardware. We start with a configuration review to understand your current rule set, identify gaps, and document the baseline. From there, ongoing management brings the policy up to standard and keeps it there.
Common issues we find during initial reviews include overly permissive rules that haven't been revisited in years, firmware multiple versions behind current, missing intrusion prevention signatures, and logging either disabled or never reviewed. These aren't unusual. They're the natural result of a firewall that's been running without active oversight.
Firewall and SASE Together
A hardware firewall secures your network perimeter at the office. For businesses with remote workers, cloud applications, and distributed teams, the perimeter extends well beyond the physical office. Secure Access Service Edge (SASE) extends firewall-level security to every user and device regardless of location, complementing your hardware firewall rather than replacing it.
STACK manages both, giving you consistent network security policy enforcement across on-premises and remote environments from a single provider.

If your firewall hasn't been reviewed in the past year, there are likely rules, gaps, and firmware versions that need attention. STACK can assess your current firewall configuration and take over ongoing management so your network perimeter stays current and effective.
