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.

Enhanced threat detection with integrated security features and good support
We are using application firewalling, WAF, and SD-WAN. The capabilities are mostly within the box. For example, you will get web application firewall WAF as part and parcel of this. SD-WAN is also bundled. It integrates with their SIEM and SOAR solutions very nicely. Lastly, the pricing point is very cost-efficient as well.

Helps maintain a consistent posture of internet security while getting rid of VPN and hovering into zero trust
There could be a better way for the tool to categorize the traffic. For example, the tool does exceptions and everything overall. If I want to give guest access or provide access to guest users or any other internet access and if it does not go through the SSL inspection because, in our company, we can't have the root certificate on a device that we don't manage, which can be called out as an exception or an exclusion, but that doesn't provide a proper reflection of the picture of what is happening in the environment. There are granularities bringing it down. The tool I used or still have is Zscaler Cloud Connector to protect the cloud environment, which can have a bit more user-friendly installation and setup, and it would help a lot. The deployment process of Zscaler Cloud Connector needs to be more user-friendly. Improvements are required in the exception category. For example, suppose I report on a monthly basis what the breaches and traffic violating the SSL inspection area are coming from. In that case, I may find that half of them may be coming through some guest network, meaning the tool doesn't differentiate between the guest or normal networks or the corporate networks. Having options to differentiate different networks would be ideal so that it can show a true picture of things to users, as half of the things in the tool are not in our control and are not of our concern.

Quotes from Members

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

Pros

"Security, SD-WAN, and Streetscape are valuable features."
"Allows for firewall rules to be programmed and named in a way that makes it “readable”"
"I'm pretty happy with its reliability. It is also very scalable."
"This product is definitely scalable."
"The wireless control is helpful."
"Offers good security and filtering."
"I really like the captive portal feature for our guest network. It has nice VLAN features in terms of separating our network. The anti-virus is also good."
"The most valuable feature of Fortinet FortiGate is load balancing. It can provide central management and VPNA. Additionally, it has enhanced our security environment."
"The absolute best part of Sangfor NGAF is their support. It's a 24/7 support channel, and the last time I requested their assistance I got a reply within three minutes. They helped solve the problem immediately."
"I think the tool has the feature to detect and kill ransomware in three seconds."
"Sangfor NGAF specializes in ransomware detection and helps to protect our network from ransomware threats and malware."
"The capabilities are mostly within the box."
"While the features are not dissimilar to other brands, configuration is much more simple, which works out great for Indonesian people."
"The stability of Sangfor NGAF is good."
"Sangfor NGAF works accordingly with our customers. The solution has good performance, easy to use, and integrates well with the endpoints."
"You might try Sangfor if you are on a tight budget. The price is affordable, and Sangfor offers a lot of features. We don't have any complaints about Sangfor."
"We like Zscaler's traffic filtering, web security, DLP, and IPS features. The real-time threat protection is excellent."
"SSL inspection is a valuable feature."
"The solution replaces multiple vendor technologies with one which makes it worth the cost."
"The security is excellent."
"Stability-wise, I rate the solution a nine and a half out of ten...The setup phase was easy."
"The initial setup was straightforward. The biggest thing for us was to build our own policies. The deployment itself was only a few hours."
"Tech support is good."
"The most valuable features I found in Zscaler Internet Access are the restriction of users for a particular URL, the security feature related to stopping DDoS, and the VPN."
 

Cons

"The ease of use could be improved."
"In most cases, the IPS engine uses too many resources, which makes Fortinet FortiGate devices unstable."
"The solution could be more evenly structured."
"The initial setup is complex."
"When we cluster the two Fortinet FortiGate boxes together we have some issues."
"Vulnerability scanning could be improved."
"I would like to see improvements in the product's application rules."
"They sometimes hide some features and if you want to enable them, you have to go in the CLI, enable the feature and configure it through the CLI. Customers, typically, like everything to be done by the GUI."
"The solution should be able to work in a hybrid setup."
"There is room for improvement in dependency on certain infrastructure, like the DNS dependency on the current DNS server that the company has. It should be standalone. It should not depend on any other DNS server."
"Lacks consistency in terms of filtering certain websites and applications."
"The tool is expensive."
"The firewall system needs gradual improvements because there are more threats and challenges every day."
"Sangfor NGAF could improve by refining its application control policies, especially in addressing challenges with certain types of applications."
"The cost of licensing is very high compared to other firewalls available here. There should be improvements in hardware scalability, allowing for more storage and memory capacity."
"The support for YouTube or the Internet is not enough."
"Cloud App’s database should be improved."
"Zscaler Internet Access needs to integrate more ISPs. It is good to have more than three ISPs."
"The solution's pricing is on the higher side. It would be better if it could be lower."
"The solution can be improved by advancing some of the newer technologies such as the DLP feature, and adding email security."
"It needs better integration with other applications. It takes a fair amount of regular activity to apply the by-passes because it is very strict in its restrictions and frequently you have to go in and open things up to allow the workforce to work."
"The performance needs improvement. Some areas create performance issues and, depending on the use cases, require reconfiguration to perform again."
"Zscaler does not provide dedicated IPs to each customer. Hence, they share a pool of IPs provided by Zscaler. There is a chance of blacklisting these IPs. I also do not like the multi-management portal."
"They block Zscaler IPs when the traffic origin is from Zscaler IPs. They've been blocked by certain government organizations so the end users are not able to visit those websites unless we ask them to unblock those IP. This is a bit problematic."
 

Pricing and Cost Advice

"In terms of the market, it's not a cheap product, but it's cost-effective."
"The licensing costs are very low."
"The price is highly competitive when compared to other brands that offer similar functionality."
"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."
"It was worth the money overall. It's good value."
"Fortinet FortiGate is cheaper than Palo Alto. It is about 20% cheaper."
"For the price, I'd rate it a ten because it's very cost-effective."
"Fortinet is competitive price-wise."
"If one is very cheap and ten is very expensive, I rate the tool's price as three out of ten."
"For four to five physical appliances for a licensed firewall, it costs approximately $4,000."
"The license of Sangfor NGAF can be purchased at different interval lengths, such as annually or three years. They offer a range of packages to choose from, such as combo or hybrid packages. We are using the complete solution package which includes IM, NGF and SSL VPN, and WAF."
"Price-wise, I would not consider Sangfor NGAF to be a cheap product. It is an expensive firewall solution, though not as expensive as something like Palo Alto, which is costly. However, the higher price point is justifiable given the feature set the tool provides that other firewalls may not offer in a single dedicated appliance."
"If you know you have around 200+ computer users on your network, then the Sangfor NGAF 5200-F-I model would be the minimum recommended model for that amount of users. This model includes modules for packet filtering, deep packet inspection, malware scanning, DSCP filtration, and many other features."
"We purchased one year technical support and return to factory support, and we also purchased one-year technical support services. So those were additional."
"In my opinion, the price of the tool is good in the Pakistani market. We can easily get discounts if needed."
"It costs about 8 to 10 thousand dollars per year for 500 users, standard licensing fees included."
"It is a few pounds per user per month."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"If we need any extra features, the price will increase."
"The pricing is an issue. It is expensive compared to other firewalls on the market."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"The price is competitive. It's not cheap and it's not expensive."
"It is quite expensive. It does its job, but it is quite expensive for what we need."
"The pricing for Zscaler Internet Access could be made cheaper."
