The most valuable features of Fortinet FortiGate are the APIs. They are the most widely known.
The most valuable features of Fortinet FortiGate are the different types of profiling. It has been the most effective for me. The WAF and the antivirus profile are the most effective in network protection.
It is very easy to use. The interface is quite understandable. There is a good community, and I can take over at any time I want. If there is anything wrong with it, I could just reinstall the whole thing and start all over again, and I'll be up again in less than a few minutes
Check Point offers virtualized systems, making it easy to scale.
There is modern protection against current threats.
It brings us the ability to work from anywhere and has allowed us to work remotely without having to incur a lot of other costs. If we didn't have this type of solution, since we have so many on-prem services that are required, we would have likely lost money and been unable to deliver. We have a video services team who helped build the content for our sporting events. When you are watching a Leaf game and those swipes come by as well as the clips and things, those are all generated in-house. Without the ability to access our on-premise resources, we would have been dead in the water. So, the return on that is pretty impressive.
It has a solid network security with some robust tools. We can block unexpected attacks, especially zero-day attacks. Since they use the Pan-OS engine, they can collect attacks from all over the world and analyze them. They can then protect against zero-day attacks and unexpected attacks.
The security of the solution, thanks to the built-in unified threat management, is one of its most valuable features. Plus, one single pane of glass is all you need to manage the whole solution, and web management can be done from anywhere.
We found the initial setup to be easy.
I'm a big fan of SecureX, Cisco's platform for tying together all the different security tools. It has a lot of flexibility and even a lot of third-party or non-Cisco integration. I feel like that's a really valuable tool.
OPNsense could improve by making the configuration more web-based rather than shell or command-line-based.
It has an open license. It works very well, and there is an update every month.

Why Use Firewall Software?
Firewalls are key to network security. They prevent unwanted visitors from entering your network as well as preventing in-network users from accessing websites or servers that could potentially be dangerous. It is essential to have firewall software to protect your organization’s data devices.
Who Uses Firewall Software?
Firewalls are an essential network security component, used in both personal settings as well as by businesses that need to protect large networks of computers, servers, and employees. Within a company, the digital security team is the main user of firewall solutions, and network administrators have the greatest control and use of firewall software.
What Makes the Best Firewall?
When IT Central Station (soon to be Peerspot) users were asked about what makes the best firewall, they described a number of factors that will help anyone make the right choice. Some security professionals want to know what is the best free firewall? IT Central Station reviews suggest that this is a question that should be asked only after one has assessed many basic requirements about usability and features first.
Visibility is offered as one of the most critical aspects of an effective firewall. Users want global reports and traffic visibility as well as application visibility. IT Central Station members also want the firewall to provide visibility into specific users’ behaviors. Visibility as a key point of value cuts across different types of solutions, including Windows firewalls, firewall software and network firewalls.
Ease of use and simplicity of administration also rated as high priorities for firewall buyers. A firewall should be easy to manage and configure. Easy installation is essential, as is integration. According to IT Central Station reviewers, firewalls typically function in complex, heterogeneous security environments. In parallel, solid vendor support is important. Reviewers noted that the first line of response to an issue with a firewall is almost always an in-house technical resource. That resource needs to be trained easily. If training is too cumbersome or if the firewall admin is a hard-to-find hire, the department will suffer.
Firewall users list many specific functions as “must haves.” These include intrusion protection (IPS), VPN, high throughput, data loss prevention, SSL, IPSEC, application control and web content filtering. Some users want a firewall to easily integrate with an LDAP Server or Radius Server. Anti-spam is desirable, as is anti-virus and anti-spyware protection. Users emphasize the importance of IPv6 native support as well as traffic shaping and bandwidth control.
Kinds of Firewall Software
Firewalls can either be either hardware or software. It’s best to have both kinds. A physical (hardware) firewall is a piece of equipment that you install between a gateway and the network. A software firewall is a program that you install on each computer, that regulates traffic through applications and port numbers.
- Packet-filtering firewalls are the most common kind. They examine packets and block those that do not match the established security rules. (Usually this means that the packet’s source and destination IP addresses must match those that are “allowed.”) There are two kinds of packet-filtering firewalls. Stateless firewalls lack context when examining packets independently of one another. This makes them easy targets for cyber criminals. Stateful firewalls, on the other hand, remember information about packets that have previously passed and therefore are considered more secure. Packet-filtering firewalls provide very basic protection but they can be limited.
Next-generation firewalls (NGFW) have an added functionality in addition to traditional firewall technology. This might include intrusion prevention systems, encrypted traffic inspection, and antivirus NGFW also includes DPI ( deep packet inspection, which examines the data within the packet itself rather than only looking at packet headers. This enables users to identify, categorize, or block packets with malicious data more effectively.
- Proxy firewalls filter network traffic at the application level. The proxy, unlike a basic firewall, acts as an intermediary between two end systems. Proxy firewalls use both deep impact and stateful inspection to detect malicious traffic.
Network address translation (NAT) firewalls operate on routers. They allow multiple devices with independent network addresses to use a single IP address to connect to the internet. This keeps the individual IP addresses hidden, providing greater security because it means that attackers can’t capture specific details. NAT firewalls are similar to proxy firewalls in that they act as intermediaries between a group of computers and outside traffic.
- Stateful multilayer inspection (SMLI) firewalls filter packets at the transport, application, and network layers, and compare them against known trusted packets. Like NGFW firewalls, SMLI firewalls examine the entire packet and allow them to pass only if they pass each layer individually. SMLI firewalls examine packets to ensure that there is only communication with trusted sources.
Firewall Software Features
Access Control - Firewall solutions act as a gatekeeper, only allowing authorized users to enter the network.
- Custom Restriction - Network administrators are able to dictate what servers and websites network users are allowed to access. These can be set to block non-business-related websites as well as to block IP addresses or servers of potential or known threats.
Alerts - If there is an attempt at unauthorized access, firewall solutions will send an alert about it to network administrators detailing the breach. This both helps admins understand potential threat sources as well as letting them know who within the network may be trying to access sources they shouldn’t be.
Automation - One benefit of firewall software is the ability to automate some of the menial tasks of network administration, such as rule-testing and monitoring. This leaves administrators with time to focus on other things.
Reporting - Some firewall tools will document all kinds of data, such as logins, access points, penetration attempts, and security failures.
- Integration Capabilities - Check prospective products’ integrations lists to see how they match up with your company’s existing IT strategy and software. Various integrations and plugins can provide functions such as content filtering, device support, and data integration.
Top Firewall Comparisons
When evaluating Firewalls, what is the most important thing to look for?
You’ve been tasked with selecting a Firewall for your company. You’ve started researching different solutions, and the options are endless. What aspects of firewalls are most important when choosing one?
IT Central Station users have given their opinions of what is the most important aspect to take into account when evaluating firewalls. With a wide variety of opinions in the answers, one thing is clear – there isn’t one single aspect that can determine what’s the best firewall.
One user emphasized that the first step in selecting the right firewall starts with knowing what your network needs are: “The most important aspect to look for is relative to one question: How informed are you with the actual needs of your network? Overall I think there are too many specific details to choose any one primary aspect when selecting a security appliance and/or firewall device based on functionality alone.” He further explained that each individual case requires in-depth research depending on one’s specific network needs.
Bearing in mind that there are many considerations, here’s a snapshot of a few of the aspects that users mentioned:
- Extensive logging
- Good support
- Good reporting abilities
One user noted that opinions on what is the “best” firewall differ widely, and that firewalls and firewall vendors as well as the people that implement them are very partial to what they are familiar with. He suggested that the right question to ask is, ”What are you looking for and need in a firewall?”
Another user, Ray KIngdon, pointed out that the most important considerations for selecting a firewall are budget and the person managing the firewall: “If you spend £40k on a firewall and have an idiot configure it and administer it – the firewall is next to useless, what ever vendor's product you buy!!”
