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.

Enhances security with precise access control but has integration challenges
Overall, I would rate the product six out of ten. Because of the support and cost, I moved away from Cisco, but otherwise, it is a good product. Recommendation depends on the requirement. If lacking a proper team and being dependent on the OEM and partner, Cisco is not suitable. However, if the team is qualified with Cisco-certified people and the requirement is a big network, it can be considered. In today's hybrid work world, having an expanded gateway is more typical than having a single one. Thus, Cisco is unlikely to be recommended for a hybrid requirement unless in-house skills align. Otherwise, depending on partners and Cisco, it can be a risk. I rate the overall solution six out of ten.
Eddy Ramirez - PeerSpot reviewer
Good interface and firewall capabilities and overall easy to use
The security has improved as we can isolate the network. We can do attrition prevention via a tool that comes with the solution. We can have a VPN solution in place for those that work from home, outside the network, in a secure manner. We also like that it offers good authentication. It offers radius-based authentication, which has been useful for the company. The main platform is under the Open VPN firewall. The solution has high availability. When we have different ISPs, we can actually load balance those links or actually put some priority or even classify the traffic that might go into one ISP or another.

Quotes from Members

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

Pros

"It is useful for protecting and segregating the internal networks from the internet. Most of our customers also use the FortiGate client to connect to their offices by using the VPN client, and of course, they usually activate the antivirus, deep inspection, and intrusion prevention services. They are also using it for web filtering and implementing various policies dealing with forwardings, NAT, etc."
"The security features are about the best that I've seen anywhere."
"Unified Threat Management (UTM) features."
"The UTM feature is quite good. FortiAP is easy to deploy because both Fortigate and FortiAP are under the same brand. Otherwise, you need to do more work on the configuration."
"The features that I have found most valuable are the SD-WAN and their IP4 policy."
"The most valuable feature of FortiGate is FortiView which provides proactive monitoring."
"The initial setup is straightforward."
"The product offers very good security."
"I have not contacted technical support. There is a lot of information on the internet for troubleshooting. All you need to do is use a search engine and you will find the information you are looking for easily."
"A stable and solid solution for protection from external threats and for VPN connections."
"It's protecting the organization against the impact of cyber threats and cybersecurity. We run manufacturing plants that have hazardous material, and we don't want that manufacturing process to be impacted by break-in exposure, cyber threats, or any other similar thing."
"We feel that we can trust the security, and our assets and business are well protected. We need to have trust in it, but we also see that it works. We have a security company that has tested that it works."
"Once configured to suit your needs, these firewalls are rock solid appliances."
"Valuable features include AnyConnect, double translations, and an independent IPS module."
"It is very stable compared to other firewall products."
"I have integrated it for incidence response. If there is a security event, the Cisco firewall will automatically block the traffic, which is valuable."
"The IDS and IPS features are valuable. From the usability perspective, there is a lot of good documentation. As IT professionals, we found it very easy to configure the firewall. It was easy to configure and use."
"The solution has high availability."
"The solution is good for a basic firewall for a small business or for home use."
"It's open source."
"What I like best about OPNsense is that, as a firewall, it's pretty good. I'm quite impressed with it. I had an excellent experience with OPNsense, which helped me achieve the targets I wanted."
"The most valuable feature is the Dual WAN in OPNSense, which offers advanced capabilities."
"The DNS-level filtering is impressive for thwarting time scanners."
"I feel that its valuable features are that it is simple and free."
 

Cons

"Bandwidth usage in reporting could be improved for Fortinet FortiGate."
"I need user-behavior analytics, to find threat scenarios from inside the organization, insider attacks. That would be very helpful for us. In addition, I would like next-generation features for small and medium businesses. These businesses require UTM, all in one product. Fortinet must include it."
"NGN, reporting and controls."
"I think the only issue that needs improvement is the interface."
"This product needs to have an analysis feature, rather than having the analysis done through the integration of a different product."
"The product does need better support in the cloud environment. It's not exactly cloud-native right now."
"Backup can be improved."
"The solution needs to improve its integration with cybersecurity."
"When we're looking at full-stack visibility, it can be difficult to get the right information out of Firepower."
"At times the product is sluggish and slow"
"They should improve their interface."
"In the future, I would like to be able to use an IP phone over a VPN connection."
"The SSL VPN is, and always has been, painful to configure and the Java plugin does not guarantee a uniform deployment."
"I wouldn't give them a ten. Nobody is perfect. I'll give them a nine because they help me with any issues I've had."
"It is not easy to configure."
"Cisco should redo their website so it's actually usable in a faster way."
"The solution could be more secure."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
"The user interface could be improved, and the DNS section should be more intuitive."
"On the customer-side, because I'm a small business, I need a cheaper or free solution option."
"The interface isn't so friendly user. But we have some technicians here who are quite confident with this tool. OPNSense could maybe add sets of rules so it's simpler to manage different groups with particular needs."
"The interface of the solution is an area with shortcomings."
"The interface needs to be simplified. It is not user-friendly."
"We did not like the fact that you have to configure everything with the graphic user interface. We have used other firewalls, such as FortiGate, that you can configure via code. OPNsense is not easy to integrate. When you are deploying via GitHub or another source repository, this is not possible. That's one thing we didn't like much."
 

Pricing and Cost Advice

"The price of FortiGate is average and I would say that based on the top five products available on the market, it is in the affordable range."
"The main reason we chose Fortinet FortiGate was that the price was better than the competition."
"The pricing of the solution is very competitive."
"Pricing is lower than Cisco."
"Its price is normal. If I compare it with other vendors, such as Palo Alto, it's normal. Palo Alto is expensive."
"Fortinet is reasonable in pricing and licensing. Overall, FortiGate is affordable. The licensing fee can be a little high, depending on the budget for your project."
"It was probably about $2,500 per firewall. It was all included. It included support, services, threat management software, and 24/7 FortiCare on it. Cisco products are more expensive."
"It is not a very costly product if you compare it with other products. The return on investment is also good. If you compare the return of investment and money that you are spending on this product with Palo Alto, Cisco, Check Point, and other solutions, the investment is very less. We are happy with this solution. The optional licenses are there, and you can choose which one you want and which one to avoid."
"The cost of the firewalls versus the ROI is okay."
"The licensing is not as complicated as that for some other Cisco products. There are a couple of tiers of licensing, but the price point is a little too high for the market. There are other vendors that come in lower and offer more for fewer licensing options. They may offer URL filtering or malware filtering with a single license rather than requiring two or three licenses. I think Cisco could do a bit more in this area."
"ASA pricing seems high compared to other firewalls, such as the Sophos XG models."
"The price is comparable."
"The pricing for Cisco products is higher than others, but Cisco is a very good, strong, and stable technology."
"The price of Firepower is not bad compared to other products."
"Cisco is not really cheap, but there is great technology behind it."
"The ROI is good. Using ASA, we have saved 10% to 20% on our costs."
"It's not expensive."
"There are no licensing costs for OPNsence."
"OPNsense is an open-source solution and it is free to use."
"I'm using the free version of OPNsense. I didn't check the pricing for the solution because I still need to test it before getting the approval to purchase OPNsense, and it isn't easy to get approval from the higher-ups."
"OPNsense is a well known open-source tool."
"It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source."
"It is free."
"The solution is not expensive."

Cisco ASA vs. Palo Alto Networks
Cisco ASA vs. Palo Alto: Management Goodies You often have comparisons of both firewalls concerning security components. Of course, a firewall must block attacks, scan for viruses, build VPNs, etc. However, in this post I am discussing the advantages and disadvantages from both vendors concerning…
