Room for Improvement

Juniper SRX Series Firewall's usability can be challenging due to its complex GUI and convoluted CLI syntax.

There are also calls for improved documentation, technical support, and better integration with third-party applications. The firewall is noted for limited reporting and performance when utilizing advanced features, while the pricing and device scalability leave room for enhancement.

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."

Implementation delivers robust security with room for a more intuitive interface

Pros

"The solution has absolutely high stability."

Cons

"The weakest point of Juniper is the graphical user interface. With a better user interface and graphical interface, the Juniper SRX Series Firewall could be a superior solution compared to what it is now."

What is our primary use case?

One of our customers uses the Juniper SRX Series Firewall. I am a Juniper customer, and we talked about earlier, I usually work as a subcontractor. I implement Juniper solutions as a subcontractor under other bigger companies, typically for medium and enterprise clients.

What is most valuable?

I appreciate Juniper software solutions, though the Juniper SRX Series Firewall is similar but slightly different than the physical Juniper firewall SRX. The routing, Layer 2, 3, 4 solutions in the network layers are valuable features. I appreciate Juniper firewall solutions.

Good encryption algorithm that helps with efficient network traffic encryption but doesn't provide UTM solutions

Pros

"We have no issues regarding hardware performance."

Cons

"It's unexpected that market support is very limited now, and SRX firewall will become obsolete and reach end-of-life."

What is our primary use case?

We use it for our IPsec VPN and for IT security and have enabled encryption on the network traffic. We use 128-bit encryption.

How has it helped my organization?

We have a very small branch office firewall, and enabling security features would degrade our traffic performance. That's why we only use IPsec VPN.

For example, we have not enabled threat management capabilities in Juniper.

Good for threat prevention, and offer easy access, setup, configuration, and connection

Pros

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

Cons

"If Juniper needs improvement, they should work on the price point because it's very high."

What is our primary use case?

Normal use cases like policy creation, infrastructure setup, VPNs, and general firewall functionality. 

How has it helped my organization?

If a company uses the SRX firewall, they don't need additional security measures to control cyberattacks. The firewall is enough to contain them.

Useful telecom industry functionality, simple deployment, but lacking features

Pros

"The IPS functionality of Juniper SRX is useful in the telecom industry."

Cons

"In comparison to other enterprise-level firewalls, such as Cisco FTD, Cisco has improved significantly. In the past, I believed that Juniper SRX was superior, but after seeing the advancements in the FTD platform, Cisco has better functionality. I have not recently explored Juniper SRX's next-generation firewall capabilities as we only use basic firewall filtering in our enterprise network."

What is our primary use case?

We are using Juniper SRX for general protection. We are not using those next-generation features, we are using them as layer 4 protection only.

On the enterprise side, we are currently only using traditional firewalling and do not have extreme-level features, such as IPS or UTM. This is because the team overseeing this area has been handed over to us in the last few years.

When we were doing the migration from the CRBV to ERV ports, at that particular time, we were working on the Juniper SRX.

What is most valuable?

The IPS functionality of Juniper SRX is useful in the telecom industry.
