Unified security and sd-wan have improved uptime and cut wan costs for multi-site branches

Users report stability issues in certain versions, which requires regular updates. Real-world attacks have also highlighted the need for urgent patching of vulnerabilities.Fortinet FortiGate, while a powerful and feature-rich web firewall, could improve in areas like firmware stability, documentation, and ease of use. The learning curve can be steep for some users. For beginners, support quality can vary, and frequent updates with occasional vulnerabilities call for careful patch management. However, once Fortinet FortiGate is configured, it remains highly reliable and efficient. Customer support needs improvement, as I find it very slow, with reports from other users reflecting that customer support is inadequate.

Head Of Bluechip Enterprise at a manufacturing company with 51-200 employees

Provides strong protection and multiple use cases but struggles with market recognition

There aren't specific areas for improvement; however, they're not as well known as the big vendors such as Palo Alto. Menlo Secure is a smaller company with limited resources and funding, which makes it challenging to compete with larger companies such as Palo and Cisco. What can be improved is market awareness and adoption of the technology. When selling it in the channel, regardless of how good the technology might be, success depends more on market adoption and awareness.

Principle Cloud Architect at a tech services company with 11-50 employees

Has provided strong traffic visibility and efficient policy management for advanced network environments

Palo Alto Networks K2-Series could be improved, though I don't think of much. I'm unsure how widespread the adoption for K2-Series alone is. Looking at the base Palo Alto capabilities, they are going in the right direction. K2 specifically about its efficacy with all these 5G protocols, the GPRS tunneling protocol performed without many hiccups during testing. With AI, if there is a Precision AI bundle that you're planning on exploring, then that definitely needs a significant uplift because currently it doesn't work for all the known models. There are many false positives that need to be addressed. While it's still ahead of its competitors, on the AI security side, there is quite a room for improvement.

Quotes from Members

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

Pros

"The solution provides good threat intelligence feeds."

"The Fortinet FortiGate local partners were good."

"I think that the UTM features are the most value, as it truly protects my infrastructure."

"The next-gen features, the unified threat management capabilities are something that just about everybody is interested in at this point."

"With Fortigate, I find fewer attacks and the console easily alerts me about possible attacks so I can prevent the malware attacks."

"I would recommend Fortinet FortiGate IPS as it is a core component of cybersecurity for our company."

"The most valuable feature is the ease of use."

"The most valuable features of Fortinet FortiGate are the ease of use and there are several operating systems that can include the hardware capacities."

More Fortinet FortiGate pros

"We are not aware of a single compromise from the web since implementing the solution."

"We have definitely seen ROI, as we save a ton of money and time because the numerous hits that we were receiving from our security tools prior to implementing them had to all be chased down, dispositioned, and endpoints had to be reimaged."

"Either you have access to something or don't have access to it, and if you do, we can ensure, 100 percent of the time, that there is nothing malicious that is going to impact our system in any way."

"Accessing the internet with a proxy from anywhere is the most valuable feature. It ensures that users are only able to browse legitimate websites. If they happen to go to a legitimate website with a malicious payload, the isolation feature will take care of that."

"This security technology addresses risk and enables people to conduct business without that risk, which is where the ROI is realized."

"For us, the primary goal is protection on the web, and that's extremely important. We're not using any of the other services at this time. The web part is key to the success of the organization. It gives us the ability to protect. It can isolate. It opens the session in an isolated format so that the code isn't running locally. It is running over in the Menlo environment, not in ours. It is not running on the local computer, whereas if you were to go to a normal website, it would run Java or something else on the local machine and potentially execute the malicious code locally. So, it does give us that level of protection."

"The solution is invisible to our end users, so it doesn't have any impact on their work or performance."

"The fact that it is a cloud proxy solution is another feature we like. For example, if you acquire a new company, you can use it to protect that new company without the need to install anything physically on their networks."

More Menlo Secure pros

"Simple integrations with the domain controllers and other inventories"

"From a security/cost-benefit perspective, it's one of the best."

"The thing I like the most about Palo Alto is that the IPS system is the strongest you can get."

"The most valuable feature of Palo Alto Networks K2-Series is the performance which is above their competitors. The throughput they have delivered is good. When we used other solutions they failed the deployment when we were using different rules. They have a theory perform performance light and performance degradation. However, Palo Alto Networks K2-Series never fails in that scenario."

"The scalability of the product is quite high."

"The most valuable feature of Palo Alto Networks K2-Series is the configuration, it is very clear."

"Palo Alto's App-ID is what differentiates it from other competitors."

"Palo Alto has a unique solution for DNS security, which is very good."

More Palo Alto Networks K2-Series pros

Cons

"We had some issues in the beginning while setting it up, but after doing the firmware update, it is working fine."

"The scalability could be better."

"Right now, it's not really scalable, but it's okay for us. However, looking ahead to three years from now, we might have a problem with scalability. We foresee a little risk down the road. The stability is okay for now."

"The firewall engine is not so strong as of now, in my opinion... My second concern is that, while they have Zero-day vulnerability and anti-malware features, the threat engine needs to be strengthened, its efficiency can be increased."

"Customer support is poor. Sometimes I open a critical ticket only to have customer support respond in four to five hours, reflecting that customer support is very weak."

"Fortinet FortiGate needs to improve the protection, it did not prevent us from being attacked."

"In terms of what could be improved, the SD-WAN is quite difficult, because if you install the new box, 15 is okay, but if you change from an old configuration, if there is already configuration and a policy when you change to SD-WAN, you must change the whole policy that you see in the interface."

"Fortinet FortiGate could be improved in terms of user friendliness at the policy level and assigning URL based and keyword based features."

More Fortinet FortiGate cons

"We are now transitioning to another solution. The main reason for that is that managing all of the exceptions and troubleshooting all of the issues our users have had connecting to the internet has become too significant in terms of workload, compared to what we hope we will have with another solution."

"The user monitoring could still be improved."

"Currently, I don't have a good way to see which of my rules are being used in the access control lists."

"Menlo Secure is a smaller company with limited resources and funding, which makes it challenging to compete with larger companies such as Palo and Cisco."

"In the best of all worlds, we wouldn't have to make any exceptions. However, that is a big ask because a lot of that depends on how websites are constructed. For example, there are some very complex, application-oriented sites that we end up making exceptions for. It is really not that big an issue for us to make the exceptions. We feel like we are doing that without a huge impact on our security posture, but we do have to make some exceptions for complex sites, e.g., mostly SaaS-type sites and applications."

"Currently, I don't have a good way to see which of my rules are being used in the access control lists. I have numerous entries, but are they all still needed? A report that would show me my list of who is allowed and whether we're actually using it would be useful because I can then go clean up my list. It would be easier to manage. We would eliminate the vulnerability of unused services."

"In the best of all worlds, we wouldn't have to make any exceptions. For example, there are some very complex, application-oriented sites that we end up making exceptions for."

More Menlo Secure cons

"It would be really helpful to have dashboards that provide information on IOC blockings such as where and how many. It will also be good to know how many hashing files have been reported. It would also be nice to have easy access to this information. Otherwise, it's a painful, manual task."

"Palo Alto Networks K2-Series is an expensive solution, the price could be reduced."

"The eight-by-seven support is not good in that case if you need it often or at times when it is not available."

"They should implement the features that the other firewalls have."

"If we have issues, they take anywhere from two days to a week to respond. I even wrote to their CEO because there was no response. When it comes to support, this is the worst company."

"The user interface could be improved. Right now, it's an aspect that is lacking."

"The scalability of Palo Alto Networks K2-Series is good. It is good for larger environments over smaller ones."

"The tool needs to improve integration with more products from other vendors. I would like the product to add threat intelligence features as well."

More Palo Alto Networks K2-Series cons

Pricing and Cost Advice

"It is more expensive than Sophos. Fortinet is overall more expensive than Sophos. The small range of Fortinet, such as 60F and 80F, is more expensive than the small range of Sophos. Sophos is cheaper. In addition, if you jump from 80F Series to 100F Series, the price doubles."

"The solution's price is average."

"Fortinet is the least expensive solution."

"For our organization, the licensing costs are approximately $7,000 per year."

"The pricing is based on a licensing model for each IPS in your environment."

"We are currently evaluating a Palo Alto solution, and the pricing could be a reason for going for Palo Alto."

"Its pricing is good. The advantages of Fortinet FortiGate over its competitors include good pricing and meeting our requirements at a lower cost."

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

More Fortinet FortiGate pricing and cost advice

"We save a ton of money and time. Previously, the numerous hits that we were receiving from our security tools, prior to implementing them, had to all be chased down, dispositioned, and endpoints had to be reimaged. It was just a ton of effort to do all that. That is where the savings from time and money come in."

"It is appropriately priced for what they're doing for us. Considering the protection provided, I feel their pricing is spot-on."

"The solution is expensive. It's more expensive than the solution I previously used. Compared with the other cloud-based solutions, it's very competitive."

"Products by the leader in the field are justifiably a bit more expensive compared to other vendors."

"The price of the solution is expensive."

"If you compare K2-Series' quality with its price, I think it is reasonable."

"The pricing is expensive."

"This is an expensive solution, although you will get value for the price."

"We are on an annual license to use Palo Alto Networks K2-Series."

"Palo Alto firewalls are very expensive."

"When comparing Palo Alto Networks K2-Series with other solutions it is on the higher end of the price scale."
