What is the pfBlockerNG alternative for users migrating to OPNsense from pfSense?
We endorse the Zenarmor next-generation firewall as an alternative option for pfBlockerNG on OPNsense or as an additional security measure to be implemented in front of your DNS filtering mechanism, pfBlockerNG on your pfSense firewall. Zenarmor is a swift, effective, economical, and straightforward solution to implement. Zenarmor is the best pfBlockerNG alternative for users who switches pfSense to OPNsense. Even Zenarmor Free Edition provides similar functionality for IP blocking and DNS filtering. In addition to providing the same level of security as pfBlockerNG systems, it also has powerful reporting and analysis tools, a large database of real-time cyber threat intelligence, easier management, and more adaptability. It utilizes its technological advancements to respond swiftly to emerging cyber threats and to perpetually enhance its threat detection capabilities. Zenarmor Free Edition is available for a perpetual free trial in a non-commercial setting.
Considered a highly practical OPNsense plugin, Zenarmor is an exceptionally popular web content filtering and application control application within the OPNsense community. The Zenarmor team has conducted extensive testing prior to its release, just as they did with pfBlockerNG. Since 2017, Zenarmor has been deployed in thousands of networks across the globe, including those of residences, small businesses, and some enterprises. The stability and dependability of the system that Zenarmor offers give rise to confidence in its suitability for production networks.
It is important to the Zenarmor team that their software can work in all Layer 3–4 traffic-processing networking environments. This includes containers, the cloud, virtual, and bare-metal deployments (firewalls, switches, and UTMs). As of December 2023, the supported platform list includes CentOS, AlmaLinux, Rocky Linux, Debian, Ubuntu, and FreeBSD, in addition to OPNsense® and pfSense® firewalls.
Zenarmor, which is installed on the OPNsense system, is configurable and manageable via the OPNsense graphical user interface and the Zenconsole cloud management portal. The Zenarmor engine, when installed on pfSense software or other SVN-supported Linux firewalls like Centos, Ubuntu, or Debian, enables global management via the cloud management portal of Zenarmor. If you have multiple firewalls installed, you can manage them all from a single web page using the centralized firewall management feature of the Zenconsole cloud management portal. Additionally, a centralized policy, which is a shared Zenarmor policy across all firewalls, can be defined and implemented.
It is clear that Zenarmor's centralized administration is useful and appealing for security administrators, especially MSSPs who are in charge of many firewalls.
Zenarmor possesses robust logging and reporting functionalities. You have the ability to sort the reports by column or field or apply a filter to them. However, Zenarmor offers more sophisticated analytics and reporting capabilities. For each of the six categories of report views, "live session explorers" are available. Additionally, it offers forty distinct varieties of infographics. The reports provide the ability to drill down to the charts and examine session details. Zenarmor also provides the capability to export reports to PDF or PNG files, which can then be emailed. Additionally, the user interface of these reports is extremely intuitive, providing administrators with a pleasant work environment.
Support at Zenarmor is cordial and accommodating. Forum, Web-based Bug Reporting Interface, and Email are three channels through which Zenarmor engineers can be contacted for assistance. Additionally, they are extremely active on Reddit and OPNsense forums. Additionally, Zenarmor offers paid support plans for purchases, contingent on the user's needs. If your IT team lacks experience or you lack the necessary knowledge to secure your home or SOHO network, Zenarmor's excellent support may be the optimal solution for you.
What are the Differences Between OPNsense and pfSense Software?
pfSense® Software is distributed under a separate license from OPNsense. While pfSense® Software is distributed under the Apache 2 license, Opnsense is licensed under a license approved by the open-source initiative. The Apache 2 license restricts pfSense® software users' ability to modify the system for a variety of purposes. On the other hand, users of Opnsense are free to redevelop the code for other purposes.
On the Netgate Blog, software release announcements and updates for pfSense® are posted. A public release schedule is not yet available, and content is released when it is complete. Netgate provides as-needed maintenance releases, typically a couple per year. These releases contain primarily issue adjustments and security patches.
The update schedule for OPNsense, on the other hand, consists of two main releases per year that are updated every two weeks. The version number of main releases includes the year and month of release (for example, 21.1 for the January 2021 release), with fortnightly updates adding a third number (for example, 21.1.4 for the fourth update to 21.1).
CVE (Common Vulnerabilities and Exposures) lists for both projects are given below. Although pfSense® has more vulnerabilities, this is an expected result because it is an older distribution. The most important aspect is that neither project has a significant security flaw.
Figure 2. Security Vulnerabilities of pfSense Software by Year and Type
Figure 3. Security Vulnerabilities of OPNsense by year
Another critical aspect of security is how quickly are the security patches released to resolve known security vulnerabilities. Though both pfSense® and OPNsense are secure, OPNsense has a slight advantage due to regular security updates
Although pfSense® Software has a larger user community, OPNsense has a more friendly and helpful community. You may be banned from the pfSense® forum for asking the wrong question or your topic may be removed because it violates the forum rules. Also, running pfSense® software on hardware other than the Netgate appliance is not welcome by the pfSense® software community. Netgate forum has more restrictive rules than the OPNsense forum.
One appealing aspect of the OPNSense community is that it has produced a large number of community plugins in a relatively short period of time. OPNsense has more than 70 different community-contributed plugins at the time of writing.
The main distinction between these two systems is their usability. OPNsense rebuilt the entire front-end interface from scratch and OPNsense GUI is more modern and organized in a more logical manner than pfSense® UI.
OPNsense dashboard is made up of menus on the left-hand side, whereas the pfSense® software dashboard is made up of drop-down menus. The list of menus on the left side of the dashboard makes it very easy to use Opnsense because it is well organized and simple to navigate. This also makes the system more intuitive and simple to use without assistance, particularly for those who are just learning how to use a firewall.
Another user-friendly feature of OPNsense is that it provides a search bar to find a menu element that you don’t know where it is. pfSense® software doesn’t have such a useful feature. Besides, it may be difficult to find the Reboot and Halt System buttons hidden under the Diagnostics drop-down menu for newcomers in pfSense® software. On the other hand, finding the Reboot and Power off buttons of the OPNsense is a piece of cake.
Both of these operating systems are mature, packed with features, and supported by an abundance of online documentation. OPNsense has a more appealing user interface and appears to add new features faster than pfSense.
If you prefer a more contemporary interface and require specific features, such as a captive portal, OPNsense may be the superior option. It is obvious that OPNSense shines in terms of user interface and usability. If you value stability, pfSense may be a superior option for you.
