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.

Robust security measures and cost-effectiveness meet diverse industry needs

The biggest benefit of Juniper SRX Series Firewall overall is that it is rugged and cost-effective, offering basic firewall features and additional licensed features as needed. The main challenge I see as a distributor is Juniper's rating in the Gartner report, where Juniper is not a leader in enterprise security, which often influences customer conversations. Most customers want to check the Gartner report before they engage, making it challenging to sell Juniper security. With my extensive experience with the Juniper SRX Series Firewall, the robustness of the SD-Cloud or Security Director interface and overall functionality needs to be improved to compete with leading firewall solutions.

A highly scalable solution that helps monitor and block undesired, non-standard traffic

Zscaler Cloud Firewall is a cloud-based solution. Zscaler Cloud Firewall is a good product. Since it's a SaaS product, most of the maintenance of devices is eliminated, and it is bundled with your secure web gateway. People should use Zscaler Cloud Firewall for their remote users or work-from-home users. Overall, I rate Zscaler Cloud Firewall a nine out of ten.

Quotes from Members

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

Pros

"The solution is stable."

"The system is very easy to scale."

"Fortinet FortiGate is easy to use."

"The ECC management and the GUI that offers single interface management are the most valuable features of Fortinet FortiGate."

"It does a lot for you for intrusion protection and as an antivirus. The threat management bundle is worth the money. You don't need another company to monitor your web traffic for you. You can do everything yourself on the firewall. You restrict your own black list for people on the firewall. You don't need to pay some other company for another product to do that for you. The firewall can do that for you. So, it's an easy-to-use product for people to be independent. They don't need to rely on other vendors to do what the firewall can do. They can do everything."

"The best feature of Fortinet FortiGate is the IPS or IDS implementation."

"There is a tool called FSSO, which is a single sign-on user ID agent that works perfectly."

"Fortinet FortiGate has positively impacted my organization, offering ease of management with no network disruptions; it works seamlessly."

More Fortinet FortiGate pros

"Troubleshooting with the solution is quite easy. If you compare the process to, for example, Fortigate, Juniper is much easier."

"Once a customer starts to use Juniper products, they never switch to another brand."

"The deployment is quite easy and fast."

"It uses many applications, like antivirus blocking and web filtering."

"We have no issues regarding hardware performance."

"The most valuable features are the security cloud ACP and KPP features."

"The product provides good performance and has features comparable to other leading products in the market."

"It's easily scalable."

More Juniper SRX Series Firewall pros

"Zscaler is still a very good product."

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

"Most of the features that Zscaler has to offer, we will deploy."

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

"It helps a lot of companies to reduce their downtime. Also, It helps businesses in terms of being secured and protected from any threats."

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

"The initial setup is straightforward."

"The solution offers good sandboxing."

More Zscaler Cloud Firewall pros

Cons

"Lacks sufficient security options."

"Overall, the integration could be better."

"The support from Fortinet FortiGate could improve. They are not easily accessible when we need them. They could improve their response time."

"Fortinet FortiGate is not very easy to use. The navigation could be improved to make it easier to use."

"There should be some open-source training or free training for decision makers, or some webinars should be available."

"My only complaint about FortiGate is a lack of QinQ VLAN tunneling. I haven't found this feature in any Fortinet product. You can do this on all Cisco routers, including the smaller models. However, QinQ isn't available on the biggest, most expensive Fortinet units. They still don't have that. I think now we're on software version 6.0, and they still haven't found a solution for QinQ. It isn't a dealbreaker, but that's my main complaint."

"I would like reporting to be improved and should offer a lot more tools to monitor the products."

"There is a lot of improvement needed with SSL-VPN."

More Fortinet FortiGate cons

"There is room for improvement in customer service and support."

"The Juniper product has to improve in terms of innovation."

"In terms of other features, I'd like to see a web filter, 10 point control, application control and a DNA filter in the next release."

"The range of devices should be expanded to include those suitable for a small implementation. Juniper does not have any lower-priced SRX models, useful perhaps for a single ATM or a single bank branch."

"It was very difficult to deal with and required a lot of support, and the UI is very poor."

"Sometimes committing configurations takes a lot of time in Juniper because of the connections, and it could be a little bit faster."

"Improvements can be made to the GUI. The GUI can be improved by creating policies to handle IPS requirements. The configuration should be a one-step process. This would make it easier to complete the setup to register the time of operation."

"It must be 5G ready. The 5G network is rolling out soon in India, and Juniper must upgrade their firewall slot to the 5G network, or they must manufacture a 5G dongle card for the Juniper firewall. I want Juniper to upgrade their dongle from 4G to 5G. Presently, they have an expansion slot in the SRX 322 series and higher firewalls. In that expansion slot, they can put a 4G mobility SIM card so that whenever our primary link is down, it will automatically connect through this GSM network and form a tunnel."

More Juniper SRX Series Firewall cons

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

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

"It would be nice to have some sort of a form factor, a physical form factor perhaps, or virtual machine that you could install on devices or on a cloud, and have some cloud computing."

"Zscaler Cloud Firewall should have a better understanding of all dynamic cloud applications."

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

"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."

"When it comes to customer support, there is room for improvement in Zscaler's service."

"The issue right now is probably that Zscaler is not providing web browser isolation. Another solution, Menlo, offers this. For one customer, we had to send traffic to Menlo to do the isolation for us. It was requested by the customer so that they could integrate any iframe. Zscaler needs to add this type of feature in their next release."

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."

"The Indian market is different than the European and American markets. When you compare they need to be a bit more aggressive on pricing."

"FortiGate SWG is a cost-effective solution well-suited for organisations of all sizes."

"The product is expensive."

"FortiGate Next Generation Firewall costs our company around $12000 per year."

"The price of the license and warranty can be better because it is very expensive."

"Fortinet Secure SD-WAN delivered the lowest total cost of ownership (TCO) per Mbps among all other vendors."

"Its pricing is good. The advantages of Fortinet FortiGate over its competitors include good pricing and meeting our requirements at a lower cost."

More Fortinet FortiGate pricing and cost advice

"It is not that expensive."

"In general, their price definitely couldn't be cheaper."

"Compared to other vendors, the pricing of this solution is good."

"This is a cost-effective solution because the price is very reasonable, and some of the features are available at no extra cost."

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

"This is an expensive product."

"I would say about $20,000 for a SRX650 with IDP licence."

"The pricing is very inexpensive which is the main reason I bought the solution. One device costs around 50 EUR through the University's vendor who is modernizing our network."

More Juniper SRX Series Firewall pricing and cost advice

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

"There is an annual license required for the use of the Zscaler Cloud Firewall."

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

"There are different subscription models available."

"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."

"It is expensive for small businesses."

"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."

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

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."
