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.

User-friendly and excels in documentation, making it easier to resolve issues

Cisco IOS Security is a mature product with extensive capabilities, serving as the base for the defense layer. It offers good network visibility, which helps in rapid response through the Rapid Threat Containment feature. Its deployment and configuration are straightforward. From a networking perspective, for instance, Cisco IOS incorporates time-tested security features. The zone-based firewall feature has significantly influenced our network security management. For instance, when managing multiple geolocations, it's essential to apply geographically appropriate policies. If a customer operates within the UK zone, I need to implement UK-specific policies. This approach is also applicable to customers in the Asia Pacific and UK regions. It enables me to tailor security policies based on the geographical location of my customers, such as adjusting policies for customers in China or Japan. This flexibility helps in creating a comprehensive zone list. Additionally, this feature allows for seamless service agreements between all zones from headquarters, providing access to all zones within the firewall we create. Essentially, it facilitates the creation of zones within the firewall.

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

"The most valuable features are SD-WAN, application control, IPS control, and FortiSandbox."

"It's a firewall that secures our internal network. I have been using it since 2013, and I find that most of the features are advanced, and very user friendly."

"The solution is scalable."

"The strengths of Fortinet FortiGate include network security, VPN, site-to-site tunnels, client VPN solutions, two-factor authentication for VPN clients, and SD-WAN for branch level. We have implemented these solutions for various customers."

"Fortinet FortiGate is used to prevent security failures. Since implementing the solution, we have seen improvements in security and in the distribution of our network."

"The payment function for applications is good."

"The ability to set up remote systems is the most valuable feature."

"The Fortinet FortiGate local partners were good. I did not have direct contact with Fortinet support."

More Fortinet FortiGate pros

"The most valuable features are DNS service and shell self-service within a network."

"Cisco has always been a premium product. There's a lot of other entry-level solutions. This is more robust."

"The most valuable feature is endpoint protection."

"You can scale it when you need to."

"Completely integrates branch offices with perimeter security."

"The hardware is pretty stable. It's also a very good product performance-wise. Initially, it wasn't mature like a firewall and there were other leaders, but now they have included almost all the features of next-generation security. Basically, it's a good product to work with."

"One of the valuable features of the solution is its flexibility and it performs great."

"One of the main features is that the hardware is extremely reliable."

More Cisco IOS Security pros

"The technical support from Zscaler was excellent."

"Includes advanced tech protection."

"Zscaler Cloud Firewall understands the applications in the current generation and adapts to the present generation cloud applications."

"Zscaler provides effective protection against various cyber threats ensuring a safe environment"

"I like the ease of deployment and its flexibility. We don't need to deal with license, quotes, procurement, delivery, and installation. Everything is software-based, and it's very easy to operate."

"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."

"It helps a lot of companies to reduce their downtime. Also, It helps businesses in terms of being secured and protected from any threats."

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

More Zscaler Cloud Firewall pros

Cons

"Fortinet technical support is lacking, as OEM support is slightly better."

"In the future, I would like to see improvements made to cloud-based management."

"Fortinet FortiGate could improve by having a frequent ask questions(FAQ) area for people to receive quick answers to popular questions. Additionally, it would be beneficial to have an SMS notification feature. For example, if you cannot access your email you could receive an SMS message."

"The documentation available for Fortinet FortiGate should be improved"

"I would suggest that Fortinet add sandboxing to their solution."

"Its customer service could be better."

"The solution could have licensing fees reduced in the future."

"Fortinet FortiGate is not very easy to use. The navigation could be improved to make it easier to use."

More Fortinet FortiGate cons

"It would be ideal if the solution had more capacity."

"The configuration and reporting interfaces need a lot of improvement. It needs to be more accessible forsolide without a strong technical background. If you had a simplified dashboard, the lower-level techs could manage the solution and provide services. Cisco IOS Security requires someone who is highly trained to operate it."

"In the next release of this solution, we would like to see support for the 100BT and 7000 models."

"The pricing is the only con for this product."

"I wish it would be more like the next generation firewall technology. There should be more selection between the application and filtering."

"Cisco is an expensive firewall, so the pricing can be improved."

"The solution is complex and can be more user-friendly."

"The solution’s setup process could be better."

More Cisco IOS Security cons

"When it comes to customer support, there is room for improvement in Zscaler's service."

"Because it's on cloud, it doesn't allow application of extra settings."

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

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

"It would be nice to have some sort of a form factor, a physical form factor perhaps, or virtual machine that you could install on devices or on a cloud, and have some cloud computing."

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

"There are some areas it could improve when it comes to blocking, we have to block some things manually. For example, if we block a top-level domain we have seen that the new IPs come through, the IPs are not blocked. There should be some more granular way of doing it. My only request is if you're blocking something at a top level, the sub-level sub-domains and all those other IPs should be blocked too automatically."

"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."

Pricing and Cost Advice

"A year or two years back, its price was competitive and reasonable. That was one of the reasons that people easily switched to Fortinet. Over the last two years, the prices have increased drastically. However, the prices of others have also increased. An advantage is there from the price point but not as much as it was previously."

"The beauty is the price performance ratio is great with FortiGate. It provides all the features we needed and the price is comparable with others' firewalls. The price is quite competitive with the firewalls with similar features."

"Its price is affordable and lesser than Cisco. Cisco is expensive. In terms of licensing, there is only one issue. If a customer's license has expired a month ago and they do the renewal after one month, Fortinet renews the license from the start of the previous month. The activation of the product is done from the previous month, not from the date of renewal. The customers usually shout and complain that because they are paying today, the renewal should start from today. The support contract renewals or licensing should be renewed from the date of renewal, but Fortinet starts from the day it had expired. It is a loss for customers. They might have had some problems because of which they did not take the license one month before. Fortinet should work on this. Cisco doesn't do this. Cisco always starts from the day they apply for the license."

"The license of Fortinet FortiGate should be reduced."

"Fortinet FortiGate's price can be reduced."

"The price for the device and software is high. However, the solution is of good quality and has a lot of features."

"The price, in comparison to other products is very cheap."

"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."

More Fortinet FortiGate pricing and cost advice

"The tool could be priced lower. If you want advanced services, then you need to purchase them."

"We need to pay for the license and it is expensive."

"The pricing for Cisco IOS Security is reasonable compared to other Cisco products."

"Palo Alto networks are more expensive than this solution and this is why you will see more products like this one in Mexico."

"The pricing is expensive."

"The price of the solution should be cheaper, and the license is purchase annually."

"You can get a better price if you commit to a longer-term license. Three years, five years, or even seven or ten years will be cheaper than a three-month or one-year term."

"The cost may be around $5,000 to $10,000 a year. If you want support you have to pay at least this price."

More Cisco IOS Security pricing and cost advice

"The licensing is on a yearly basis. It is somewhere around 30 or 40 pounds per user for our organization."

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

"There are different subscription models available."

"There are licensing costs, and I would not say that it's a cheap vendor."

"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."

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

"The product is a bit expensive compared to the solutions offered by its competitors, like Palo Alto. There is a need to make yearly payments towards the license in charges associated with the product."

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