Cybersecurity can feel like a never-ending task, especially when threats keep evolving. But strong firewall management is what helps ensure that your security tools are actually doing their job – protecting data, supporting compliance, and keeping business running.
Businesses have seen weekly cybersecurity attacks grow by 58% over the past two years,1 and firewalls are often the first line of defense. Without the right management strategy in place, even the most advanced firewalls can leave gaps that attackers are ready to exploit.
At Aseva, we help businesses implement and maintain firewall management solutions that streamline security strategies. Read on to explore the different ways to approach firewall management and best practices to help you stay ahead of threats without overcomplicating your infrastructure.
Key Takeaways
- Firewall management is the ongoing work of configuring and maintaining firewalls through policy management, rule management, and change management, supported by monitoring and updates.
- It matters because unmanaged firewalls drift over time, and that drift leads to misconfigurations, broader-than-needed access, downtime risk, and compliance headaches.
- Common approaches include cloud firewall management, on-premises management, fully managed firewall services, and management tools that centralize policies, rules, and events.
- Best practices include automating repetitive tasks, monitoring continuously, documenting changes, reviewing rules on a schedule, and planning capacity as your environment grows.
What Is Firewall Management?
Firewall management is the process of configuring and maintaining firewalls to effectively protect your IT environment. This typically involves:
- Defining and enforcing access rules
- Updating firewall software and firmware
- Monitoring logs and alerts for threats
- Ensuring policies meet compliance standards
Without consistent firewall security management, it can be easy for gaps to appear. Rules become outdated, access permissions grow too broad, or policies fall out of sync with business needs. All of that creates risks that can lead to issues like downtime or breaches.
In practice, firewall management breaks into three areas: policy management, rule management, and change management, the process that keeps updates controlled and auditable.
Core Components of Firewall Management
Firewall Policy Management
Firewall policies define who and what can access your network – and under what conditions. Clear, well-managed policies reduce confusion and help keep your IT environment secure.
Best practices include regularly reviewing your existing firewall policies, documenting each change, and applying the principle of least privilege. This means giving users or systems only the access they truly need, and nothing more.
Firewall Rule Management
Firewall rules are what actually enforce your security policies. They determine how traffic flows in and out of your network, and whether it gets blocked or allowed.
Rule sets can become cluttered over time. A new service gets added, a user leaves, or a quick fix turns into a permanent exception. These small changes add up and can make your firewall harder to manage.
That’s why it’s important to regularly clean up rules, use clear naming conventions, and prioritize the rules that support your mission-critical traffic.
Firewall Change Management
Firewall change management is the process of planning, approving, and documenting updates to your firewall policies and rules. It helps you avoid risky “quick fixes” that turn into permanent exceptions, and ensures changes stay aligned with security and compliance requirements.
Best practices include using a clear request and approval workflow, reviewing the impact before deployment, scheduling changes during defined maintenance windows, and keeping a rollback plan ready if something breaks. Just as important, every change should be logged and documented so your firewall stays predictable, auditable, and easier to manage over time.
Why Does Firewall Management Matter?
Firewall management plays a major role in your overall security posture. If you’re not actively maintaining your firewall, there’s a good chance it’s not doing its job. A properly managed firewall offers advantages like:
Reduced Risk of Misconfigurations
Improper configurations are one of the top causes of network breaches, with Gartner estimating that 99% of firewall breaches in 2023 were due to misconfigurations.2 Even a small error in a rule or access control setting can expose your entire environment to threats.
Adapt to Modern Threats
As security threats evolve, your firewall needs to evolve too. Attackers are always finding new vulnerabilities in traditional defenses, so it's important to stay on top of firmware updates, vendor patches, and rule optimizations.
Meet Compliance Requirements
Industries subject to data privacy regulations like HIPAA, PCI DSS, or GDPR are required to maintain strong access controls and logging, both of which fall under firewall management. Auditors will often review firewall management policies to verify compliance, and around 60% of firewalls fail these high-severity compliance checks.3
What Are the Main Types of Firewalls?
Different firewall types don’t just filter traffic in different ways. They also change how you manage policies, rules, and performance day to day. Understanding the differences helps you build a strategy that fits your environment, instead of creating extra operational work.
Traditional Firewalls
Traditional firewalls (stateless and stateful) focus on IPs, ports, and protocols. They’re familiar and effective, but they often depend on large rule sets that require disciplined rule ordering, regular cleanup, and ongoing hardware lifecycle planning for on-prem appliances.
Next-Generation Firewalls (NGFWs)
NGFWs add deep packet inspection, application awareness, and advanced threat prevention. That usually means more granular policies to maintain, tighter coordination across security and networking teams, and more tuning, logging, and integration work to avoid alert fatigue and policy sprawl.
Cloud Firewalls & FWaaS
Cloud firewalls and FWaaS shift enforcement closer to cloud workloads and users, while offloading infrastructure upkeep to the provider. Management focuses on centralized policy across environments, aligning cloud and on-prem controls, and coordinating changes with provider SLAs and change windows.
Proxy Firewalls
Proxy firewalls sit at the application layer and act as intermediaries between users and external services. They enable detailed content and application controls, but they add another control point to monitor and tune, and they require careful capacity planning to avoid becoming a bottleneck.
Common Firewall Management Challenges
Even well-managed firewalls can become difficult to maintain as networks grow and change. These are the issues that tend to show up first, and the ones that create the most risk if they’re left unchecked.
When “Temporary” Rules Become Permanent
Rule sets rarely stay clean. Exceptions get added for new apps, quick fixes turn into long-term workarounds, and outdated entries stick around. Over time, that clutter makes the firewall harder to manage and easier to misconfigure.
Keeping Policies Consistent Across Sites and Cloud
As you add locations, cloud workloads, and remote users, it’s easy for policies to drift. Different teams may apply different standards, which leads to uneven enforcement and gaps that don’t show up until there’s a problem.
Not Knowing What Traffic Is Really Doing
Even if the firewall is blocking threats, visibility can still be limited. Without clear logging and monitoring, it’s hard to explain why traffic was allowed or denied, and issues often surface late as downtime or a security incident.
Changes That Accidentally Break Critical Access
Firewall updates can disrupt business-critical traffic if they’re rushed or poorly tested. Without a defined change process and a rollback plan, small adjustments can turn into outages and long troubleshooting cycles.
Staying Ready for Audits and Compliance Reviews
Many organizations need to prove that policies are controlled, reviewed, and documented. If changes aren’t tracked and rule intent isn’t clear, audits become painful and compliance gaps are easier to miss.
Types of Firewall Management
Different organizations require different approaches to firewall management depending on their IT environment, team resources, and security posture. Some of the most common models are:
Cloud Firewall Management
Cloud-based firewall management offers flexibility and central oversight for workloads moving off-site. It’s especially useful for hybrid or multi-cloud environments where consistent policy and rule management across multiple systems matters. Policies can be applied across every cloud platform and adjusted as your needs change.
Managed Firewall Services
If you’re looking for a hands-off approach, working with a managed services provider may be the best fit. Aseva’s team of vendor-neutral technology advisors can help you find a managed security provider that monitors, updates, and manages your firewalls so that your IT staff can handle other tasks.
On-Premises Firewall Management
With on-premises firewalls, your team is responsible for managing all hardware and software. This option gives you full control but requires more time and expertise than cloud or managed versions.
Firewall Management Tools
The right firewall management tool can simplify oversight by centralizing policy, rule, and event data. They’re especially helpful when you’re juggling multiple firewalls or locations.
Look for tools that include:
- A centralized dashboard to manage policies and rules
- Automated alerts for unauthorized changes or suspicious activity
- Visual tools for analyzing traffic paths or rule overlaps
- Integration with SIEM or SOC platforms for broader visibility
Aseva can help you select and implement the best firewall management tools for your specific business needs – and ensure they’re configured to meet your security and compliance goals.
5 Best Practices for Firewall Management
Following a few best practices can make your firewall management smoother and more effective. These are the strategies we recommend to clients looking to improve their cybersecurity posture without adding unnecessary complexity:
1. Automate Where Possible
Automation tools can streamline repetitive firewall management tasks like software updates, rule validation, and monitoring. This reduces the risk of human error and threats slipping through the cracks.
2. Monitor Continuously
Firewall logs offer valuable insights, but only if someone is looking at them. Review any alerts in a timely manner, either by your team or with support from a managed security provider.
3. Document Everything
Keep clear records of all policy changes, rule updates, and configuration settings you make to your firewalls. Documentation helps during compliance audits and makes it easier to onboard new IT team members.
4. Regularly Review Rules
Set time on the calendar to clean up any outdated, redundant, or overly broad rules. We recommend doing this at least twice a year to keep your firewalls effective.
5. Plan for Growth
As your business grows, so does your network. Make sure your firewall management plan includes capacity considerations, including adding new locations, devices, or services.
Firewall Security Management in Hybrid Environments
Managing firewalls can be more complex if your IT infrastructure includes on-prem systems, cloud apps, and remote users. You may even be using different types of firewalls across multiple environments, each with its own configuration tools and policy frameworks.
Without centralized oversight, this patchwork approach can lead to inconsistent rules and visibility gaps.
Aseva’s cybersecurity experts bring it all together. We’ll help you find a managed firewall solution that unifies policy enforcement, centralizes monitoring, and pushes updates across cloud and on-prem systems so that your firewalls always work together, no matter where they’re deployed.

Firewall Management FAQs
What are the 5 steps of firewall protection?
- Define security requirements and what traffic should be allowed.
- Build policies and rules based on least privilege.
- Deploy and validate (test critical apps, confirm logging).
- Monitor traffic, logs, and alerts for threats and anomalies.
- Maintain and improve with regular updates, reviews, and rule cleanup.
What are managed firewall services?
Managed firewall services are when a provider handles day-to-day firewall operations for you. This typically includes configuration, policy and rule updates, patching, monitoring, alert response, reporting, and change management (often with SLAs), so your team has less operational burden while staying secure and compliant.
When does it make sense to move to managed firewall services?
Managed firewall services are worth considering when you struggle to keep up with patches, rule changes, monitoring, and incident response, or when your environment has grown more complex than your team’s available time and expertise. They’re also a strong fit when you need 24/7 coverage but don’t want to build it in-house.
Can I use multiple firewall types in one environment?
Yes. Many organizations combine traditional firewalls, next-generation firewalls, cloud firewalls, and even proxies. The key is to manage them under a unified strategy so policies are consistent, logs are usable, and changes don’t create conflicts between platforms.
What metrics should I track to improve firewall management over time?
Focus on a small set of metrics you can actually act on, such as unused rules, failed changes, mean time to respond to alerts, and the number of firewall-related audit findings. Use trends in those metrics to drive process improvements, tool changes, or shifts in ownership.
