A stable solution with an intuitive interface and quick customer service

I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

Though it helps deal with web traffic or any malicious traffic, it needs to work on its DC performance issues

The product's initial setup phase is moderate in level, so it is neither very complex nor very easy. For the deployment, my company first needs to gather all the requirements of the users and the domain names and consider how many users there are in the company. In the implementation and planning part, my company needs to consider what kind of policies we will create while ensuring that the policies are created based on the requirements of the users. There is a need to segregate the users' requirements since there are separate departments in the company, like the HR department, sales department, IT department, and manufacturing department, so that our company can create policies depending on their requirements. On-site, if you want a GRE tunnel, our company can handle GRE tunnel traffic routing and Zscaler Cloud Firewall, after which Zscaler will take action based on the policies created by our organization. For the deployments and maintenance, a team of five members consisting of two managers and three engineers is required.

Quotes from Members

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

Pros

"Fortinet FortiGate is a security device. It can optimize security on the networks of a company. It actually protects the company from attacks from outside. With FortiGate, you can categorize the users. You can create a group of users that can access all of the websites for their work. You can limit other users' access."

"The IPS is good. It protect my network from attackers."

"It is easy to use. We chose this product for the possibility to have virtual domains (VDOMs). We are building another company in the group, and we would like to split the firewalling rules and policies between these two companies. Each company would be able to manage its own policies and security rules, which is an advantage of Fortinet FortiGate. We can define VDOMs, and every company can manage its own VDOM as if it has its own physical firewall, but in fact, we would be using the same physical appliance because we are also using the same internet lines. So, it allows us to reuse the existing resources without the disadvantage of having to compromise on policies and security. Each company can choose its own way of working."

"Application control and the web filter are the best features of Fortinet FortiGate."

"Fortinet FortiGate is a scalable solution."

"SD-WAN has had a positive impact by reducing the operational costs in terms of headcount and management."

"Fortinet FortiGate has SD-WAN, FortiView, antivirus, sandbox, and IPS, which are generally well-known features."

"I have found Fortinet FortiGate to be scalable."

More Fortinet FortiGate pros

"We mostly use the Layer 4 firewall functions: Access rules, NAT, and site-to-site IPsec VPN."

"The ports are really versatile for their application and don't always have to be used for the purpose for which they were made."

"The EEE security controls allow us to make policy restrictions, so I can customize port numbers to allow or limit control."

"The solution has proven to be quite stable."

"If we need to define our user system from an anti-spam perspective, we can constantly update the antivirus."

"vSRX is easy to deploy to any virtual infrastructure, such as OpenStack, VMware, and even Docker (cSRX)."

"Technical support has been quite helpful."

"There are a lot of security features."

More Juniper SRX Series Firewall pros

"If malicious traffic attacks our on-premises servers, then it gets blocked by Zscaler Cloud Firewall."

"Since it is really customizable, I can use it and avoid enabling access to the full network."

"The solution offers good sandboxing."

"Once you have Zscaler running you have access to configure it however you want."

"The visibility and log availability offered are highly valued for troubleshooting purposes, and this is a key factor driving customer interest in the firewall module."

"The scalability is okay. We have around 2200 people using this solution."

"The product’s firewall and VPN package are fantastic compared to any other solution."

"Zscaler is still a very good product."

More Zscaler Cloud Firewall pros

Cons

"In my opinion, Fortinet FortiGate could be improved by making the appliance smaller than what we have here, as it is pretty big."

"It would be ideal if they had some sort of GUI interface for troubleshooting and diagnostics."

"Palo Alto has a feature called WildFire Analysis that is unavailable in FortiGate. WildFire is better than a sandbox because it can address zero-day threats and vulnerabilities. It can immediately identify zero-day threats from the cloud."

"I'm not sure if it's something that they already have or are developing something, however, we need some dedicated features for container security."

"From my experience, I see that the datasheets of the Fortinet FortiGate portfolio need to be more accurate because correct sizing is essential. The datasheets should provide clear information when deploying features."

"We faced difficulties with the configuration because there are many features we could optimize using Fortinet FortiGate, but our reseller didn't have a good understanding of it. So, we just use it on a basic level, not with the best practice for using FortiGate."

"The Web-filter in this solution is not very good."

"Its reporting capabilities can be improved. It should have some out-of-the-box reporting capabilities and some degree of customization. The basic reporting that it currently has is not sufficient to create more usable reports. It needs some sort of out-of-the-box reporting. They try to make customers purchase FortiAnalyzer for this kind of reporting, which is an additional cost. Other firewall vendors, such as SonicWall and Sophos, provide this sort of reporting without any additional cost."

More Fortinet FortiGate cons

"I think improvement can be done to the security part, particularly the UDM, and the product should have a user-friendly interface similar to FortiGate. It should have the Azure RBAC in the next release."

"The CLI is verbose. You have to say a lot to do a little. I don't like that part of it. Cisco's command syntax seems to be a good bit more concise. When you're trying to get something done, you don't want to have to type a bunch."

"The solution's initial setup process was lengthy as I was new to Juniper."

"I would like to see endpoint control and endpoint testing security."

"Does not offer protection for IoT devices"

"The web interface on Juniper SRX is just a short conversion from Junos OS CLI; this is not very suitable for users with little expertise/"

"It could improve areas which need high performance."

"The Juniper SRX product needs to improve in terms of innovation."

More Juniper SRX Series Firewall cons

"Its technical support services could be better."

"Because it's on cloud, it doesn't allow application of extra settings."

"Instead of the standard license, they should certainly provide customers with the visibility to access and view the logs."

"Data Leak Prevention is only for web filtering and there is no protection for email."

"They do not provide a few components that are fundamental to differentiate the products"

"Certain criteria need to be met if you want to scale this solution."

"There are some areas it could improve when it comes to blocking, we have to block some things manually. For example, if we block a top-level domain we have seen that the new IPs come through, the IPs are not blocked. There should be some more granular way of doing it. My only request is if you're blocking something at a top level, the sub-level sub-domains and all those other IPs should be blocked too automatically."

"Apart from the issues associated with the product in areas like the DC performance issues and DC failover, Zscaler Cloud Firewall's IP should not have a proxy IP."

More Zscaler Cloud Firewall cons

Pricing and Cost Advice

"The price of FortiGate is reasonable as I plan to buy new switches. The initial gadgets are already booted, and the pricing seems normal on the market. As for additional costs, I haven't subscribed to many extra features, so I'm only using what I need. Last year, I renewed the support for three years, which can sometimes be expensive but depends on the security benefits and how it helps us."

"We saved a bundle by not needing all the past appliances from an NGFW."

"Each feature costs money, so it is important to study your needs."

"It has been two years. I don't remember the actual price, but it was affordable. We buy the boxes and then use the license for three years."

"My experience with the pricing, setup cost, and licensing for Fortinet FortiGate is quite good. I don't have a public site, such as in Azure, where I can see the pricing. I always have to go through the distributor, and that could take some time to get the real price for each appliance."

"The price of Fortinet FortiGate is reasonable."

"Its price is good."

"The price of FortiGate support is too expensive."

More Fortinet FortiGate pricing and cost advice

"Palo Alto was nice, but much more expensive."

"In my opinion, the Juniper SRX Series Firewall is cheaper than other products."

"The price is reasonable"

"Juniper SRX is reasonably priced."

"There was no additional licensing cost because there were no IPS services. It was just a firewall IP circuit router so they have the default licensing. We just need to renew the support yearly."

"Pricing is very good, not expensive."

"The price of this solution is more than other products, but it's stable, and the technical support is better than I have seen with others."

"I rate the solution's pricing as a four."

More Juniper SRX Series Firewall pricing and cost advice

"It comes at a significantly reduced cost while ensuring control and effectiveness."

"There are licensing costs, and I would not say that it's a cheap vendor."

"The licensing is on a yearly basis. It is somewhere around 30 or 40 pounds per user for our organization."

"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing an eight out of ten."

"There are different subscription models available."

"The product is a bit expensive compared to the solutions offered by its competitors, like Palo Alto. There is a need to make yearly payments towards the license in charges associated with the product."

"It is expensive for small businesses."

"Zscaler is priced too high compared to the cost of Fortinet."

Juniper SRX is a next-generation security solution that enables users to expand and secure their networks without incurring heavy costs or sacrificing performance.

Benefits of Juniper SRX

Some of the benefits of using Juniper SRX include:

Easily manage and view every aspect of your system’s security. Juniper SRX enables users to manage their security from a centralized location. The central control center can control and view every Juniper connected device in a user’s network. Once a device meets the desired security requirements, an administrator can configure the device’s policy to match the other machines in their network. This both simplifies the way that the network operations run and decreases the number of resources that are needed to ensure that operations run smoothly.

Secure your system with a flexible and comprehensive security suite. Juniper SRX’s firewalls are flexible enough that they always match the type of applications that they are supposed to be protecting. Its security features uniformly protect your applications. This is true regardless of how your application is deployed. It can integrate with everything from cloud-based applications to those stored on physical servers in a data center. This makes it easy for administrators to maintain consistency across their systems.

Protect yourself from advanced threats. Juniper SRX is equipped with powerful security automation features. They can detect a wide range of known and unknown threats as soon as they appear. Once malware is detected, Juniper SRX begins to analyze it and determines what response fits the situation. Additionally, the threats are prioritized according to their severity. Administrators are then given a selection of response options from which they can choose. This enables users to prevent the spread of these threats.

Increase your ability to scale your security. Juniper SRX makes it easy for users to scale up their security to meet their specific needs. Its service processing cards (SPC) are designed to enable a user to meet all of their needs. Administrators do not need to buy specific hardware every time that they need to get something done. Their SPCs can be quickly and easily customized. The addition of SPCs enables users to scale up according to the particular project that they are working on at that time.

Reduce the number of resources that you need to expend. Juniper SRX enables users to add expansion modules to their network without expanding the cost to run their network. They accommodate growth without adding to the overall cost. Administrators will not need to spend money on more space, cooling power, or maintenance. Additionally, they will not have to dedicate more time to maintaining the network. Your network may grow, but the cost of running your system will not.

Reviews from Real Users

Juniper SRX stands out among their competitors for a number of reasons. Two major ones are their central management capabilities and the robustness of their suite of security features. Juniper SRX is designed to make it easy for users to take control of their network’s security. From one location, administrators can manage all aspects of their infrastructure’s security. The many features that it offers allows users to tailor their security to meet their specific needs.

Shashidhara N., director of technology solutions & services at Connectivity IT Services Private Limited, writes, “On the SRX box, it has what I call a one model concept for security. I work especially with hybrid environments. With an SRX we have a single management dashboard. We can manage the internal framework easily with the centralized management component. You can work with threat prevention, you can work with integration, you can work with traffic management. Another good part about SRX is that you have opportunities for automation. Another thing that is very good is that all the operating systems for all Juniper boxes are the same. You do not work on different operating systems using different boxes.”

Pradip J., the owner of Shree Atharva Sales Corporation, writes, “It is a complete security bundle. The cloud-based Sky Advanced Threat Prevention feature is very valuable. I am 100% satisfied with the performance of the Juniper firewall. It has a very good throughput. It works very fine. We use our firewall as a site-to-site VPN or Software-Defined Wide Area Network (SD-WAN). In both cases, it has a very good and optimum performance.Their service support is very good in India. I get really good support from the Juniper team."
