Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
5.9
Netgate pfSense provides significant ROI with cost-effectiveness, eliminating license fees, ideal for small to mid-sized companies replacing costly systems.
Sentiment score
6.2
Palo Alto Networks K2-Series improved cybersecurity, efficiency, and cost savings through enhanced visibility, automation, and reduced incident response times.
In four years of using it, that payment of 189 dollars per year has already paid off.
L2 Systems Administrator at a comms service provider with 201-500 employees
It's very favorable to have the inclusion of firewall, VPN, and router functionalities.
Owner at SimpleIT
The total cost of ownership is extremely low when you compare it to a lot of the other devices or other gateway appliances that are available on the market.
Operations Manager at a tech services company with 11-50 employees
For CN-Series, there is no competitor which works the same way as Palo Alto does.
Principle Cloud Architect at a tech services company with 11-50 employees
 

Customer Service

Sentiment score
7.8
Netgate pfSense receives praise for effective support, though some users experience slow responses; forums often suffice for troubleshooting.
Sentiment score
8.0
Palo Alto Networks K2-Series support is praised for vendor responsiveness and expertise, though partner support is less reliable.
They are highly responsive.
Network Administrator at a healthcare company with 51-200 employees
I couldn't imagine having better support.
Director of IT at Cutting Edge Hair Salon RSS
The biggest fear I have, and probably the only reason I still have the old one lying around is that if something were to happen to this hardware and I had to send it back for support, I need to be able to keep my network running in the meantime.
Co-Owner at Steffi and Tim
I would rate tech support from Palo Alto Networks at around eight out of ten points because we had dedicated people assigned to us.
Principle Cloud Architect at a tech services company with 11-50 employees
We get Gold support from them, and they are pretty good.
Design engineer at a construction company with 201-500 employees
I would rate the technical support for the Palo Alto Networks K2-Series from Palo Alto as nine out of ten points.
Director at MICROLOGIC NETWORKS PRIVATE LIMITED
 

Scalability Issues

Sentiment score
6.6
Netgate pfSense is highly scalable for SMBs, supporting high user counts and complex configurations depending on hardware choices.
Sentiment score
7.8
Palo Alto Networks K2-Series offers scalable, flexible solutions for organizations, excelling in network expansion and handling diverse environments.
If I put things into a certain context and say that we have a network that has around 100 people, then you don't put up a device that can manage 100 people. Instead, you need to get a device that can manage 150 to 200 people, and then you can create room for growth.
CTO at Vigon Business Solutions Limited
I don't think Netgate pfSense can offer much scalability for big enterprises.
Director at a tech vendor with 5,001-10,000 employees
Even with a jump from a 50 megabit to a 500 megabit internet connection and approximately 65 active VPN clients, our firewall operates smoothly without any strain.
IT Manager at a healthcare company with 11-50 employees
Vertical scaling allows you to purchase more powerful devices with additional RAM, compute, and larger model form factors.
Principle Cloud Architect at a tech services company with 11-50 employees
 

Stability Issues

Sentiment score
7.1
Netgate pfSense is highly stable, with users attributing minimal issues to hardware rather than the firewall, ensuring reliable performance.
Sentiment score
7.8
Palo Alto Networks K2-Series is praised for exceptional stability and dependability, with minor configuration and maintenance issues reported.
I rate the solution's stability a ten out of ten.
Infrastructure and integration Architect at CommunityForce
I've noticed a substantial improvement in stability and ease of use for upgrades and patching over the past year or two.
Technical Sales Specialist at a tech vendor with 10,001+ employees
When I replace consumer routers with pfSense for small businesses with two or three employees, they are often amazed to discover the router can run for a year without a reboot.
Partner and Owner at Free Range Geeks
Palo Alto typically doesn't have many glitches.
Principle Cloud Architect at a tech services company with 11-50 employees
 

Room For Improvement

Netgate pfSense requires better centralized management, an updated user interface, improved security integrations, and enhanced documentation for ease of use.
Palo Alto Networks K2-Series needs better pricing, integration, usability, and AI to address user demands for support and scalability.
If I need to go between different VLANs, I have VLAN 19.1 and VLAN 19.2, and I strictly use Netgate pfSense, but it doesn't route very efficiently and works quite slowly.
Information Security Manager at a tech services company with 11-50 employees
They should support the idea of configuration management as code from source code and provide a more robust API for managing the pfSense configuration.
Co-Owner at Steffi and Tim
Monitoring is crucial. The easier the monitoring and user interface, the simpler our team can work on and investigate issues.
Infrastructure and integration Architect at CommunityForce
Enhancing web traffic protection would be a great upgrade.
enterprise architect at a tech services company with 1-10 employees
L1 engineers cannot work on the Palo Alto Networks K2-Series because it's too complex, which requires L2 and above level of engineers.
Director at MICROLOGIC NETWORKS PRIVATE LIMITED
With AI, if there is a Precision AI bundle that you're planning on exploring, then that definitely needs a significant uplift because currently it doesn't work for all the known models.
Principle Cloud Architect at a tech services company with 11-50 employees
 

Setup Cost

Netgate pfSense is affordable, offering open-source and paid versions with robust features and competitive hardware pricing.
Palo Alto Networks K2-Series is expensive, suitable for large enterprises, with straightforward licensing but requires frequent price negotiations.
It also offers a free community version that can't be beaten.
Owner at Shaffer Consulting
Since I'm using my own hardware instead of a Netgate appliance, this is the most bang for your buck you can deploy.
Owner at a consultancy with 1-10 employees
There are cheaper firewall options, but they aren't as reliable and easy to manage.
Managing Director at IPC Solutions Pty Ltd
It's a little bit expensive.
enterprise architect at a tech services company with 1-10 employees
The pricing for the Palo Alto Networks K2-Series solution is affordable.
Director at MICROLOGIC NETWORKS PRIVATE LIMITED
 

Valuable Features

Netgate pfSense offers reliable VPN and firewall features, user-friendly management, flexibility, cost-effectiveness, scalability, and strong community support.
Palo Alto Networks K2-Series provides advanced, scalable security with AI-driven features, strong threat prevention, and user-friendly management.
I like the tool's flexibility in the sense that you do not have to buy an appliance. You can put it on your own hardware, and it can be very simplistic hardware with simple configurations.
Information Security Manager at a tech services company with 11-50 employees
The most valuable feature is the routing capability.
Managing Director at a tech services company with 11-50 employees
It is not licensed and is not run by some corporation that watches you.
Owner at Sonic Trout LLC
Overall, the K2-Series helps in much more protection, and dashboard compliances are being met.
Director at MICROLOGIC NETWORKS PRIVATE LIMITED
We had configured dynamic user groups and App-ID based policies, which makes it all Zero Trust.
Principle Cloud Architect at a tech services company with 11-50 employees
Mainly, it is very easy to understand, and the logs are very good.
Design engineer at a construction company with 201-500 employees

JA
Principal Cloud Architect - Software Engineer at a consultancy with 11-50 employees
Rapid VPN setup has connected offices in minutes and brings live insights for proactive issue control
What I appreciate the most about Netgate pfSense is the ease and straightforward nature of the platform. I can set up a new office in less than 10 minutes. The benefits of using Netgate pfSense are that I can set up VPNs in less than two to three minutes, and then just deploy the file across my networks, where everybody would be connected in less than an hour. The dashboards of Netgate pfSense bring all the necessary information that I need at a glance, and it is actually a live update every three to five seconds. It is spotless, and I have been able to catch issues before they hit operations.
TJ
Principle Cloud Architect at a tech services company with 11-50 employees
Has provided strong traffic visibility and efficient policy management for advanced network environments
Palo Alto Networks K2-Series could be improved, though I don't think of much. I'm unsure how widespread the adoption for K2-Series alone is. Looking at the base Palo Alto capabilities, they are going in the right direction. K2 specifically about its efficacy with all these 5G protocols, the GPRS tunneling protocol performed without many hiccups during testing. With AI, if there is a Precision AI bundle that you're planning on exploring, then that definitely needs a significant uplift because currently it doesn't work for all the known models. There are many false positives that need to be addressed. While it's still ahead of its competitors, on the AI security side, there is quite a room for improvement.
