Efficient, user-friendly, and affordable

In the past, NSS Labs was utilized to test files and verify the numbers and datasheets. It would be beneficial to have an organization or testing lab that can verify the numbers in our datasheets since changes are frequently made, which can be inconvenient for review. For instance, when comparing different competitors such as Forcepoint, Palo Alto, and Check Point, the throughput or numbers in the datasheet may be lower than the actual numbers. Conversely, Fortinet typically reports very high numbers, but they cannot be replicated in the real world. Therefore, it would be advantageous for them to partner with a neutral testing organization such as NSS Labs to validate these numbers, thus providing more credibility and comfort to everyone regarding the accuracy of the datasheets. For the migration, everyone has a firewall in use and I am selling Fortinet. Typically, I am replacing another firewall. Previously, there was a tool available to convert configurations from one firewall, such as Palo Alto, to Fortinet, but this tool is no longer free. If it could be made free again, it would be very beneficial. This tool shows a lot of promise and is very good. Making it free would help many companies deliver their products in a more efficient and integrated way. It would also be more valuable to include the tool with the firewall package or license instead of having to pay extra for it. Paying extra puts more pressure on small companies to deliver the firewall and complete the configuration, especially if they have hundreds or thousands of policies. It's very painful to move through these policies line by line. The stability has room for improvement. When it comes to Secure SD-WAN, everything is fine. They are going the right way. SD-WAN is very promising. They can provide the SD-WAN solution separately, but they will not take this approach because even the smallest firewall can support the features, so there is no need to have a separate service or appliance. They are following the right steps, and there is nothing to be improved. Feature-wise, I'm really satisfied with the new release, and the features they have added. For now, it's fine.

Offers a simple console to manage multiple branches and content filtering

The centralized console is great for managing multiple branches. It's a very simple console to connect all three of our branches in the US and India. We connect through three firewalls in a single console and manage any policy. So, if we need to change a policy, the global admin can connect from anywhere and easily make changes. Log usage is also very easy. The threat prevention capabilities are very good. Preventing the latest threats is very easy. You can define rules, and it automatically alerts you. For example, if there's a sudden increase in malicious spam, it will notify you immediately.

Network manager admin at Yamaha

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

"We can use our devices to check all of the perimeters. It secures email websites."

"The most valuable features of Fortinet FortiGate are the ease of use and there are several operating systems that can include the hardware capacities. In the newer releases, the resources were more useful because they were included in the operating system."

"Our security improved from being able to put in rules and close off unwanted traffic."

"The web tutor and automatic rules by schedule are good features."

"Fortinet FortiGate meets all the security demands of my industry. It covers endpoint security, including web interface, DNS security, and ELP. I'm currently using the latest version. The features that have most improved our network security are Web Control, filtering, application control, IDS, IPS policies, and Deep SSL inspection."

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

"The user interface (UI) is very, very good."

"Its performance in fulfilling our requirements has been satisfactory."

More Fortinet FortiGate pros

"The most valuable features are the VPN, SSL VPN, and IPSec VPN."

"One of the main features is the built-in storage capacity."

"The most valuable features of this solution are intrusion detection, intrusion prevention, and the advanced capture client, which provides live traffic analysis."

"The most valuable features of this solution are the GUI pre-filtering and the ATP (advanced threat protection)."

"The features that I have found most valuable are the firewalling, which is very good and the GUI which is very intuitive. It is easy to use, and provides great security."

"The solution has many useful features, such as content management, user management, user filtering, and domain controller connectivity mapping."

"I like this solution because we are focused on VPN and have many brands that need to link a VPN and have security, like ransomware, spyware, and basic protection."

"The product is working okay. The product is working feature-wise."

More SonicWall NSa pros

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

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

"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 technical support from Zscaler was excellent."

Cons

"For the migration, everyone has a firewall in use and I am selling Fortinet. Typically, I am replacing another firewall. Previously, there was a tool available to convert configurations from one firewall, such as Palo Alto, to Fortinet, but this tool is no longer free. If it could be made free again, it would be very beneficial."

"The cloud features can be improved."

"The solution could be improved by addressing limited local reporting. It requires obtaining the FortiAnalyzer for proper visibility because you can't do much from a reporting perspective with just the firewall alone."

"The user interface could be improved."

"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."

"The security of Fortinet FortiGate could improve."

"The solution lacks sufficient filtering."

"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

"We have security as a service, and they make recommendations about adding to the denylist and other things. That part could be more accessible and more user-friendly. I'd like to see SonicWall add a user-friendly interface where our internal team can drag and drop everything."

"Customer support is severely lacking with very slow response times."

"The ongoing service fees are high."

"The implementation for VLANs is a little bit cumbersome. It would be good to make that a little bit easier."

"Vendor support needs improvement. The frequency of time and support should be increased."

"The security standards for space and point of view should be improved so that the solution deploys in critical areas."

"The stability is not there. The features are there, but they are not stable. They need to improve on this product because I feel that they have launched this product without much R&D."

"The thing main thing is that there's no user admin and in other firewalls, we can enable the scalable features, but SonicWall doesn't have that feature."

More SonicWall NSa cons

"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."

"We are having some issues with internet access being denied when organizational ID-based policies change. For example, a lower level employee ends up getting the same level of access as that of a higher level employee."

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

"There are several areas for improvement. Firstly, the GUI is outdated, with noticeable lags and delays, especially when generating reports for past transactions."

"If I can get rid of Jetscaler, I will use Twingate for sure."

"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."

"Its technical support services could be better."

"I don't have the visibility of a control dashboard or a network management system."

More Zscaler Cloud Firewall cons

Pricing and Cost Advice

"If the customer is looking for SD-WAN, it comes free with FortiGate."

"The price of Fortinet FortiGate is affordable. Most of our customers are on a three-year license to use the solution. All the features and support are included in the price."

"They need to be competitive with other solutions."

"Before choosing a piece of equipment you have to take into account the cost-benefit offered by each one. Sometimes it is not worth paying a very cheap price to have a minimum level of security."

"Fortinet's pricing is more straightforward than other solutions. If Fortinet doesn't stick out when you're searching for a solution, you are a glutton for punishment. You only need to know two things when purchasing a Fortinet solution: your total bandwidth and bandwidth at the site. You need to estimate the future bandwidth with other solutions if your customer plans to upgrade."

"Fortinet costs are 25% lower than the high-cost provider. There is an equipment cost and a recurring monthly cost for licenses and technical support."

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

"In the Asian economy in which we operate, FortiGate is expensive."

More Fortinet FortiGate pricing and cost advice

"The price of SonicWall NSa is expensive."

"The CPUs are not able to compete with a similar price point to the Fortinet, WatchGuard, or Palo Alto product."

"Considering the market, I believe that the price of this solution is great."

"Compared to Fortinet and Cisco, SonicWall NSa is a cheaper solution."

"We are on a three-year license for the solution. The price is inexpensive compared to other solutions."

"The price is reasonable."

"The solution is expensive. Its pricing is based on the number of users."

"It would be better if it has a better price, but its price is okay considering the benefits that you receive."

More SonicWall NSa pricing and cost advice

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

"It is expensive for small businesses."

"It is not the most budget-friendly solution, but it's important to consider its overall value."

"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."

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

SonicWall NSa dispenses advanced threat protection using a high-performance security platform. The NSa series implements intuitive deep learning technologies in the SonicWall Capture Cloud Platform to dispatch the automated real-time threat detection and deterrence enterprise organizations need today. SonicWall Network Security appliance (NSa) series is best for mid-sized organizations to distributed enterprises and data centers.

SonicWall NSa series next-generation firewalls (NFGWS) combine two very robust security ideologies to deliver advanced threat protection to keep users’ networks safe. Boosting SonicWall’s multi-engine advanced threat protection (ATP) is their Real-time Deep Memory Inspection (RTDMI™). The RTDMI intuitively identifies and stops aggressive zero-day threats and vicious malware by investigating memory directly. This real-time process allows SonicWall RTDMI to be accurate, lessen false positives and discover and alleviate malicious threats and attacks. SonicWall’s single-pass Reassembly-Free Deep Packet Inspection (RFDPI) will audit every byte of each and every packet by investigating both outbound and inbound traffic on the firewall. By combining the SonicWall Capture Cloud Platform along with on-box offerings such as intrusion prevention, web/URL filtering, and anti-malware, the NSa series is able to block the most malicious and dangerous threats at the gateway.

Additionally, SonicWall firewalls supply absolute protection by executing complete inspection and decryption of SSH and TLS/SSL encryption connections - no matter the port or protocol. The firewall takes a deep dive into each and every packet (the header and data) routing out any anomalies, zero-day intrusions, threats, and protocol non-compliance. Users can also define unique criteria specific to their organization to ensure their networks remain safe. This aggressive deep packet inspection is able to identify and block malicious attacks, stop dangerous malware downloads, prevent the spread of infections, and defeat command and control (C&C) communications and data exfiltration. Protocols involving inclusion and exclusion allow users complete control to decide, based on specific governance policies, organizational policies, or government or legal compliance, which traffic is to be investigated for decryption or inspection.

SonicWall Nsa offers enterprise organizations the network control and fluid flexibility they desire using an intrusion prevention system (IPS), VPN, real-time visualization, and other advanced powerful security features, making it a popular firewall solution in today's marketplace.

Reviews from Real Users

“The features that I have found most valuable are the firewalling, which is very good, and the GUI which is very intuitive. It is easy to use and provides great security.” - Network Engineer at a maritime company

“What's valuable in SonicWall NSa is the ATP (advanced threat protection). It can protect users from malicious links. SonicWall NSa also has a Sandboxing service that is very helpful for us, especially when end users accidentally click on malicious links. Another valuable feature of this solution is that it is very useful for site-to-site VPN connectivity issues. SonicWall NSa has very good hardware. I also love that SonicWall has very good technical support, who are very knowledgeable, provide good suggestions, and they're easy to reach.” - Mohammed M., Network Administrator at Transgulf Readymix
