Network control and security are vital for any organization that wants to protect its data and resources from cyber threats. However, traditional firewalls and network devices are often limited in their ability to handle the complexity and diversity of modern network traffic. How can you achieve granular and flexible control over your network without compromising performance or usability? The answer is advanced policy-based filtering.
Policy-based filtering is an effective strategy for defining and enforcing distinct security policies and procedures for different categories of traffic. In this blog post, we will show you how you can master network control with advanced policy-based filtering using Zenarmor.
Understanding Policy-Based Filtering
Policy-based filtering is a technique that allows you to control and manage your network traffic based on different criteria and rules. It is crucial for network management because it helps you to:
- Enhance network security by blocking or allowing specific applications, web categories, users, IP addresses, VLANs, etc.
- Optimize network performance by prioritizing and shaping traffic based on your business needs.
- Simplify network administration using a centralized and user-friendly interface to create and monitor policies across all your network devices.
Policy-based filter matches traffic flows with predefined policies and applies the corresponding actions. A policy is a set of conditions defining what type of traffic to match and what actions to take.

Here is a step-by-step guideline to show how it actually works:
Step 1: Define the criteria for matching traffic. You can use various parameters, such as applications, web categories, users, IP addresses, VLANs, etc. For example, you can create a criterion that matches all the traffic from social media applications, such as Facebook, Twitter, Instagram, etc.
Step 2: Define the actions for the matched traffic. You can use various actions, such as block, allow, log, etc.
Step 3: To create a policy, integrate the requirements and the actions. You may give the policy an identifier and an explanation.
Step 4: Arrange the policies in descending order of significance. You can reorganize the policies by dragging and dropping them. The first relevant policy is applied to the traffic after all of the policies have been thoroughly examined.
Step 5: Set the policies to be rendered applicable only during specific periods or days. You can use a calendar and a clock to specify when the policies are active or inactive.
These are the steps involved in creating and applying policy-based filters for your network traffic. You can use Zenarmor to implement advanced policy-based filtering using a cloud-based management interface or the OPNsense WebUI.
Unleashing the Power of Advanced Policy-Based Filtering
Advanced policy-based filtering is a feature that allows premium users to leverage the full capacity of Zenarmor and gain more control and flexibility over their network security. Premium users can achieve the following thanks to the advanced policy-based filtering:
- Defining policies based on IP, MAC, and Network addresses: You can customize your security rules for different devices, users, and groups on your network. For example, you can block social media for some devices, allow streaming for some users, and restrict access for some groups.
- Fine-tuning web security to match unique requirements: This feature allows you to adjust your web filtering settings to suit your specific needs. For example, you can block gambling and adult sites for your network, allow educational and news sites for your students, and whitelist some domains or URLs for your staff.
- Flexible security options, including exempted Networks and VLANs: With Premium, you can choose to bypass filtering for trusted sources or isolate sensitive segments on your network. For example, you can exempt some networks or VLANs from filtering, such as your VPN or your servers.
- Enhanced network segmentation: This feature allows you to create separate zones with different levels of access and protection on your network. For example, you can create a public zone for your guests, a private zone for your employees, and a secure zone for your administrators.
- Granular control over network traffic: This feature allows you to inspect, block, or shape any application or protocol on your network. For example, you can inspect encrypted traffic with TLS inspection, and block malicious or unwanted applications with application control.
Benefits and Outcome
You may increase the degree of control and flexibility over your network security with advanced policy-based filtering. By implementing advanced policy-based filtering, you can expect the following benefits and outcomes:
- Enhanced security: You can block or allow specific applications, web categories, users, IP addresses, VLANs, etc., based on your security needs. You can inspect encrypted traffic and block malicious or unwanted applications and websites. This helps you protect your data and resources from cyber threats and prevent data breaches.
- Better network performance: You can prioritize and shape traffic based on your business needs. You can isolate specific networks or VLANs from each other to create separate zones for different purposes. This helps you optimize network efficiency and reduce network congestion and latency.
- Compliance with regulatory requirements: You can create policies that match the regulatory standards and best practices for your industry or region. You can log or alert you to traffic events and generate reports for auditing purposes. This helps you comply with legal and ethical obligations and avoid penalties or fines.
- Simplified network management: You can use Zenconsole, a cloud-based management interface, to control and monitor the security policies and traffic across all the deployments. You can also use the OPNsense WebUI to configure and manage policies for Zenarmor. This helps simplify network administration and reduce operational costs and complexity.
This heightened level of control, combined with the ability to inspect encrypted traffic and block malicious elements, serves as a robust defense against cyber threats, effectively safeguarding your data and resources. Zenarmor's advanced policy-based filter presents a holistic and practical approach to network security, setting the stage for a strong and efficient network infrastructure.
