For scalability, if the hardware isn't fit or working, the box needs changing.
Senior Manager Tech Compliance at Qenta Inc.
One issue I faced with scalability was the transition from Skybox Security Suite's 6500 platform to the 7500 series due to licensing costs becoming prohibitive.

Skybox Security Suite requires improvements in UI, web access, reporting, integration, pricing, support, cloud connectivity, and data processing.
The Intrusion Prevention System (IPS) in Fortinet products, including FortiGate Cloud-Native Firewall (FortiGate CNF), is not very strong; we often prefer Cisco IPS instead.
Key Executive at ITBiz Solutions
It is a tool that we have used quite heavily, but it has a lot of vulnerabilities and they are starting to be dropping support for it.
Systems engineer at The IT Team (New Zealand)
The prices for FortiGate are way too high and are perceived as overpriced.
Technical Presales at A.G.A.S. מחשוב ותקשורת לעסקים
Reporting could have been improved, and feature requests often were not implemented.
Security Engineer at a financial services firm with 10,001+ employees
Only the licensing part of Skybox had an edge. We were not renewing the licenses of Skybox every year, but in the case of other tools, we would have to renew if we wanted to use those tools.
Security Architect at a tech vendor with 5,001-10,000 employees
It would be better if something more attractive or similar useful information found in AlgoSec was available.

FortiGate's cost-effectiveness is noticeable as it provides many features with one license, saving costs compared to Cisco ASA.

The pricing is considered too high and does not justify the value provided by the devices.
Technical Presales at A.G.A.S. מחשוב ותקשורת לעסקים
From a commercial perspective, AlgoSec is more expensive compared to Skybox Security Suite.
Software Engineer at LTI - Larsen & Toubro Infotech
The pricing became prohibitive when transitioning between the 6500 and 7500 series models.

Featured Reviews

Andrew_Jackson - PeerSpot reviewer
Systems engineer at The IT Team (New Zealand)
Centralized management has streamlined access for staff and support has consistently addressed issues quickly
I see areas for improvement, particularly around the SSL VPN. It is a tool that we have used quite heavily, but it has a lot of vulnerabilities and they are starting to be dropping support for it. So we kind of see that they have left a vacuum by removing that feature. The VPN feature is indeed the main concern so far. Security around it is a concern, and then the fact that they have just dropped it and have not really provided a solution that fits for us. Their solution was either IPsec or ZTNA, which is not as flexible as the SSL VPN was for our customers.

Firewall policy management has improved access control but still needs simpler setup and upgrades
The features that I appreciated the most in Skybox Security Suite were not comparable with Tufin, as Tufin was far ahead in terms of the technology and the user interface. The effectiveness of the vulnerability management in Skybox Security Suite is an area I have not used that much. The firewall management feature has streamlined rule configuration and compliance in Skybox Security Suite and has evolved over time, but Tufin is far better. In terms of comparison between both tools, only the licensing part of Skybox had an edge. We were not renewing the licenses of Skybox every year, but in the case of other tools, we would have to renew if we wanted to use those tools. The disadvantages and weaknesses of Skybox Security Suite include the interface, complexity with setup, and upgrading. There are some smaller issues as well that would take more time to discuss, but there are ways around them. We use this tool to implement a new policy on the firewall by going to Skybox, creating a flow there, and then using an approval mechanism in place. There are two different levels of approvals which we have to go through, and once both approvers approve the request, we are ready to implement it. A specific challenge is that if we have to create a new object group and place ten different objects in that and use that object group in two different rules, we have to create the object group in the first rule and add the ten new objects. Then if we have to create another rule, we do not get an option to recall or reuse that same group which we created in the previous rule. We have to create a new object group again and then add the objects into it again. If we had created an object group once, we should have gotten an option to recall that or call that object group in the new rule, and that should have made the process easier.
