Find out in this report how the two Firewalls solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI.
I have seen a return on investment with Cisco Meraki MX because of the time saved through cloud management.
You can eliminate some positions because it manages itself.
It greatly helps out when I am moving away from the expensive MPLS circuits or MPLS hardware.
The network attacks reduced by approximately 60% after using that, even without customizing the custom configuration yet.
For a very little investment, I was able to increase the security of my network.
When we raise a ticket with Meraki MX, they instantly become available to support us for configurations or troubleshooting.
Cisco's TAC support for Cisco Meraki MX is excellent because no other OEM provides support at this level.
Cisco is one of the best vendors in the market.
Compared to some open-source projects with weak support, OPNsense stands out for having both a strong community and commercial backing options.
I mainly rely on community support since the solution is open source.
If you say you do not have one, it is finished. This is where the monopoly starts.
When you have hundreds of thousands of people it is very difficult to scale in Meraki.
The scalability of Cisco Meraki MX is rated 10 out of 10; you can scale up and scale down with no effort.
Cisco Meraki MX scales with my growing needs for my organization very well because they are easy to deploy.
I use Zenarmor, pinning it to one core for packet inspection, and the CPU performance seems very good.
OPNsense's scalability is excellent; I just need to resize my hardware and upgrade the server, and voilà, I am good to go.
In theory, OPNsense can handle small home networks and even large enterprise environments if deployed on sufficiently powerful hardware or virtualized on a clustered system.
There have been no outages, no stability issues, and we have not found any vulnerabilities during security audits.
I have had zero downtime at all with Cisco Meraki MX.
I assess the stability and the reliability of Cisco Meraki MX as good, and I have experienced no downtime, crashes, or performance issues.
For home and small network use, OPNsense is also reliable, providing enterprise-grade security at no cost.
The only challenge faced was its inadequacy to manage large voice traffic effectively, even with dedicated hardware.
At the latest code level, I haven't experienced any crashes.
It should automatically remediate and find out the issue and then resolve it on its own without interrupting the work of the employees.
Data is the only path, so optimization is essential.
An improvement would be to use Cisco Meraki MX as a software solution as well, which might reduce the cost.
Enhancing its performance for significant amounts of data traffic would make it closer to a perfect solution.
It would be beneficial if they could create some videos on how to set it up themselves.
The documentation should be clearer because I faced some difficulties navigating many options.
I get it for $25,000, a device that can connect up to 75-100 users, whereas in Meraki MX, it goes to 75,000-80,000 per access point.
The price could be reduced by around 30% to make it more comfortable.
If Cisco can make the pricing less, customers can purchase more licenses.
I consider the pricing of OPNsense to be high when compared with other market products.
OPNsense is free, the licensing and setup was easy.
Meraki MX is among those top solutions in their exceptional approach towards VPN-less, Zero Trust client access to office private networks.
Advanced security is the second tier of Cisco Meraki MX. It brings you the main next-generation firewalling features such as URL filtering, advanced malware protection, and threat protection.
Cisco Meraki MX API makes it really easy for me to automate a lot of changes over several thousand devices.
The most valuable features include the basic firewall functionality and the GeoIP location services.
I can have a Wi-Fi VLAN and feel secure that the server network or the VM network that I have on a different VLAN are isolated, and they cannot talk to one another, which adds a great level of security.
It offers enterprise-grade features such as intrusion detection and prevention system, VPN support, traffic shaping, and web filtering, all without license cost.
