Featured Review
Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"The most valuable features of this solution are the integrations and IPS throughput.""Another benefit has been user integration. We try to integrate our policies so that we can create policies based on active users. We can create policies based on who is accessing a resource instead of just IP addresses and ports.""I like that Cisco Firepower NGFW Firewall is reliable. Support is also good.""The most important feature is the intensive way you can troubleshoot Cisco Firepower Firewalls. You can go to the bit level to see why traffic is not handled in the correct way, and the majority of the time it's a networking issue and not a firewall issue. You can solve any problem without Cisco TAC help, because you can go very deeply under the hood to find out how traffic is flowing and whether it is not flowing as expected. That is something I have never seen with other brands.""I have integrated it for incidence response. If there is a security event, the Cisco firewall will automatically block the traffic, which is valuable.""I have experience with URL filtering, and it is very good for URL filtering. You can filter URLs based on the categories, and it does a good job. It can also do deep packet inspection.""I like the firewall features, Snort, and the Intrusion Prevention System (IPS).""If configured, Firepower provides us with application visibility and control."

"It is pretty stable. I haven't seen many issues during the past four years.""It's pretty reliable and allows for isolation capabilities within the network.""The most valuable feature is the anti-malware protection. It protects the endpoints on my network.""The initial setup is easy.""I think Cisco ASA Firewall is the most stable firewall solution.""It is extremely stable I would say — at least after you deploy it.""The management aspect of the product is very straightforward.""It helped us a lot with our VPNs for the home office during COVID. There has been more security and flexibility for VPNs and other applications."

More Cisco ASA Firewall Pros →

"I have used technical support quite a bit, and they are really good.""Technical support is good. They quickly respond, and they even have local help here. They can actually give you an answer very quickly.""We did not have problems with scaling, as we have less than 500 users in our organization.""The features that I have found valuable are the ones for the main purpose we are using Juniper - its firewall to protect our network for our internet access.""Juniper SRX is a very powerful firewall and sometimes can be used as a router.""It is a part of the infrastructure when we're selling Juniper. That's what clients are familiar with and that's what they rely on.""It is very fast and very easy to maintain. Another nice part of it is that you can easily extract the logs and move them over to a security operations center.""The CLI works perfectly."

More Juniper SRX Pros →

Cons
"I believe that the current feature set of the device is very good and the only thing that Cisco should work on is improving the user experience with the device.""I would like to see improvement when you create policies on Snort 3 IPS on Cisco Firepower. On Snort 2, it was more like a UI page where you had some multiple choices where you could tweak your config. On Snort 3, the idea is more to build some rules on the text file or JSON file, then push it. So, I would like to see a lot of improvements here.""It's mainly the UI and the management parts that need improvement. The most impactful feature when you're using it is the user interface and the user experience.""We only have an issue with time sync with Cisco ASA and NTP. If the time is out of sync, it will be a disaster for the failover.""When you make any changes, irrespective of whether they are big or small, Firepower takes too much time. It is very time-consuming. Even for small changes, you have to wait for 60 seconds or maybe more, which is not good. Similarly, when you have many IPS rules and policies, it slows down, and there is an impact on its performance.""There is limited data storage on the appliance itself. So, you need to ship it out elsewhere in order for you to store it. The only point of consideration is around that area, basically limited storage on the machine and appliance. Consider logging it elsewhere or pushing it out to a SIEM to get better controls and manipulation over the data to generate additional metrics and visibility.""The reporting and other features are nice, but there is an issue with applying the configuration. That part needs some improvement.""The Firepower FTD code is missing some old ASA firewalls codes. It's a small thing. But Firepower software isn't missing things that are essential, anymore."

More Cisco Firepower NGFW Firewall Cons →

"I think the ASA layer is thin. It's always Layer 3 or Layer 4 source controller and doesn't control the Layer 7 traffic. It's important, and you'll need an additional firewall.""Other products are becoming easier to access and configure. They are providing UI interfaces to configure, take backup, synchronize redundant machines, and so on. It is very easy to take backup and upgrade the images in those products. Cisco ASA should have such features. If one redundant machine is getting upgraded, the technology and support should be there to upgrade other redundant machines. In a single window, we should be able to do more in terms of backups, restores, and upgrades.""One area that could be improved is its logging functionality. Your logs are usually displayed on the screen, but if you want to go back one or two days, then you need another solution in place because those logs are overwritten within minutes.""Sometimes my customers say that Cisco Firewalls are a bit more difficult compared to Fortigate or Palo Alto. There is complexity in the configuration and the GUI could be improved.""There is huge scope for improvement in URL filtering. The database that they have is not accurate. Their content awareness and categorization for URL filtering are not that great. We faced many challenges with their categorization and content awareness. They should improve these categorization issues.""The user interface is a little clunky and difficult to work with. Some things aren't as easy as they should be.""On firewall features, Fortinet is better. Cisco needs to become more competitive and add more features or meet Fortinet's offering.""They should improve their interface."

More Cisco ASA Firewall Cons →

"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.""J-Web, Juniper Web, is sometimes not working great when users are increasing their internet use. Additionally, they need to improve the GUI, graphical user interface, and the firewall management needs to improve. Their CLI is good, but sometimes the GUI is very slow.""In the next release, I would like to have a better web interface. It needs to be more user-friendly. Right now, you can only access many features through the console.""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.""The solution could cost less. It's a bit expensive right now.""The user interface is something that Juniper needs to improve.""Both the web management and the graphical user interface are inadequate and should be improved.""The configuration is difficult and it should be easier."

Cisco provides its firewalls with the latest intelligence to stop emerging threats and employs filtering to enforce policies on hundreds of millions of URLs. Cisco NGFW offers built-in sandboxing and advanced malware protection that continuously analyzes file behavior to quickly detect and eliminate threats.

    • Comprehensive network visibility: Constantly monitor your network so you can rapidly spot and stop bad behavior. Cisco NGFW provides a holistic view of all activity and provides a clear picture of threat activity across users, hosts, networks, and devices, as well as information on threats and website, application, and VM activities.

    • Flexible management and deployment options: Centrally deploy, customize, and manage all your appliances.

    • Fast detection: Detect threats in seconds and detect the presence of a successful breach within hours or minutes. Cisco NGFW allows you to deploy consistent policy that's easy to maintain, with automatic enforcement across all the different parts of your organization.

    • Automation and product integrations: Seamlessly integrate with Cisco tools and automatically share threat information, event data, policy, and contextual information with email, web, endpoint, and network security tools. Cisco NGFW automates security tasks like impact assessment, policy management and tuning, and user identification.

    Reviews from Real Users

    Cisco NGFW stands out among its competitors for a number of reasons. Two major ones are its extensive discovery abilities that enable you to constantly see what is happening on your network and take action when necessary, and the high level of protection it provides.

    Mike B., a director of IT security at a wellness & fitness company, writes, "It is one of the fastest solutions, if not the fastest, in the security technology space. This gives us peace of mind knowing that as soon as a new attack comes online that we will be protected in short order. From that perspective, no one really comes close now to Firepower, which is hugely valuable to us from an upcoming new attack prevention perspective."

    Zhulien K., the lead network security engineer at TechnoCore LTD, notes, " The most valuable feature that Cisco Firepower NGFW provides for us is the Intrusion policy. Again, with that being said, I cannot shy away from giving kudos to all of the other features such as AVC (Application Visibility and Control), SSL Decryption, Identity policy, Correlation policy, REST API, and more. All of the features that are incorporated in the Cisco Firepower NGFW are awesome and easy to configure if you know what you are doing. Things almost always work, unless you hit a bug, which is fixed with a simple software update. "

    Cisco ASA Firewall is a security device that combines firewall, intrusion prevention, virtual private network (VPN), and antivirus capabilities. Its main purpose is to provide proactive threat defense to stop attacks before they spread through the network.

    Cisco ASA Firewall Features

    Cisco ASA Firewall has many valuable key features, including:

    • Intrusion prevention system (IPS): Cisco ASA Firewall’s IPS provides contextual awareness.
    • Advanced threat protection: Gain protection against zero day threats (based on using global threat intelligence) .
    • Rapid threat containment: With Cisco ASA Firewall, you can proactively mitigate risks. If a threat is detected, additional security policies are applied to other network devices for increased protection.
    • High availability: Cisco ASA Firewall offers high availability for high resiliency applications
    • Integrated IPS, VPN, and unified communications capabilities
    • Multi-node clustering
    • Multi-site
    • High performance

    Cisco ASA Firewall Benefits

    Some of the benefits of using Cisco ASA Firewall include:

    • Superior protection from threats through CSC, IPS, and the like.
    • Better pricing means that TCO is reduced. 
    • High performance levels that can be scaled to achieve 10+ Gbps.
    • You can deploy new applications easily over secured layers.
    • Identity-based access helps you access business resources.
    • Identity-based access can be integrated with other services, such as LDAP and Microsoft Active Directory.
    • By implementing Cisco ASA Firewall, IT resources are freed up.
    • Because Cisco ASA Firewall offers effective prevention, your spyware cleanup costs decrease.

    Reviews from Real Users

    Below are some reviews and helpful feedback written by Cisco ASA Firewall users.

    A Cisco Security Specialist at a tech services company says, “All the features are very valuable. Among them is the integration for remote users, with AnyConnect, to the infrastructure. All the security through that is wonderful and it's very easy. You connect and you are inside your company network via VPN. Everything is encrypted and it's a very good solution.” He goes on to add, “The intrusion prevention system, the intrusion detection, is perfect. But you can also integrate Cisco with an IPS solution from another vendor, and just use the ASA with AnyConnect and as a firewall. Cisco ASA also provides application control. You can block or prevent people from going to certain applications or certain content.”

    Jonathan M., Head of Information Communication Technology at National Building Society, comments, "The benefits we see from the ASA are connected to teleworking as well as, of course, having the basic functionality of a firewall in place and the prevention of attacks. The standard reports allow us to constantly monitor our environment and take corrective steps.

    Eric H., CEO at NPI Technology Management, explains, “The command-line interface is really useful for us. We script basic installations and modifications through the command-line, which is considered sort of old school, and yet it allows us to fully document the changes that we're making due to the fact that we can save the exact script that was applied and say, "Here are the changes that we made."

    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."
