What is Managed Firewall?
Managed Firewall is a fully managed service that takes ownership of your firewall infrastructure—policy design, day-to-day changes, monitoring, and optimization—so your perimeter and critical segments stay protected without overloading your internal team.
With DataComm Managed Firewall, we:
- Design and maintain firewall policies aligned with your business and security requirements
- Manage rule changes, NAT, VPNs, and segmentation in a controlled, auditable way
- Monitor firewall health, performance, and security events around the clock
- Provide expert guidance on best practices, architecture, and ongoing improvements
Instead of juggling firewall admin as a “side job,” you get a dedicated team and a proven management framework delivered as a service.
Why organizations choose Managed Firewall
Firewalls remain a core control, but they’re harder to manage than ever:
- Environments are hybrid and distributed—data center, cloud, branch, and remote users
- Frequent changes and projects lead to complex, hard-to-audit rule sets
- Misconfigurations can expose critical systems or break key applications
- Security and network teams are stretched thin and struggle to keep up with tuning and reviews
Managed Firewall helps close these gaps by combining expert policy design, disciplined change management, and 24/7 monitoring under a consistent, repeatable process.
How DataComm Managed Firewall works
DataComm Managed Firewall is built to improve security, reduce complexity, and support your business as it changes.
Discover & Assess
We start by understanding your current state:
- Inventory existing firewalls, platforms, and locations
- Review current policies, rule sets, VPNs, and segmentation
- Identify risks: overly permissive rules, unused objects, shadow policies, and inconsistent standards
The outcome is a clear picture of your perimeter and internal segmentation, plus a roadmap for improvement.
Design & Standardize
Next, we help define a clean, maintainable policy model:
- Establish standards for naming, zones, objects, and rule structure
- Align access rules with applications, users, and business processes
- Define approval, change, and documentation workflows
- Agree on security baselines, escalation paths, and maintenance windows
This gives you consistent, repeatable firewall management across sites and platforms.
Operate, Monitor & Support
Once standards are in place, DataComm runs day-to-day management:
- Implement approved changes (new rules, VPNs, NAT, policy updates)
- Monitor firewall health, resource utilization, and connectivity 24/7
- Track and respond to critical events and policy violations
- Provide support for projects and troubleshooting that involve the firewall layer
We act as an extension of your team, handling the bulk of operational work.
Review, Optimize & Evolve
Intrusion detection and prevention is not a one-time setup—it’s an ongoing cycle:
- Regular tuning of signatures, rules, and policies to reduce noise
- Adjustments based on new threats, business changes, and lessons learned from incidents
- Periodic reviews to evaluate coverage, performance, and policy effectiveness
Over time, your security posture strengthens while operational friction decreases.
SecurFirewall is the Managed Firewall solution from DataComm, built to simplify firewall administration, reduce risk from misconfigurations, and ensure your infrastructure is protected by expert oversight.
Key capabilities of DataComm Managed Firewall
We’ve designed our service around four core pillars.
Policy design and governance
DataComm helps you establish and maintain strong governance:
- Standardized rule and object naming conventions
- Zone and segmentation strategies aligned to risk and business function
- Documented approval workflows for changes and exceptions
- Policy review cycles to keep access aligned with real needs
You gain clarity about “who can talk to what, and why.”
Change management & implementation
We take care of the details behind every change:
- Intake and validation of firewall change requests
- Impact assessment to minimize disruption and avoid conflicts
- Implementation in agreed change windows with rollback plans
- Documentation of changes for audit and internal tracking
Your firewall changes become faster, safer, and more predictable.
Monitoring, health & availability
We keep a close eye on your firewall infrastructure:
- Hardware and resource monitoring (CPU, memory, sessions, throughput)
- High availability pair and cluster health checks
- Link status for internet, MPLS, VPN, and SD-WAN paths
- Alerts for failures, overload conditions, or unusual spike events
Issues can be detected and addressed before they turn into outages.
Security posture & best practices
We help ensure your firewalls support a strong security posture:
- Reduction of “any/any” or overly broad rules where feasible
- Proper use of application, user, and URL controls when supported
- Support for security services like IPS, web filtering, and anti-malware where available
- Recommendations for micro-segmentation and zero-trust-aligned designs
You get more value out of the firewalls you already own.
