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.

"I am content with its user interface and functionalities."

"The most valuable features of the FortiGate firewall include SSL inspection, VPN functionality, and threat intelligence features for preventing threats."

More Fortinet FortiGate pros

"It is easy to use with access via CLI and GUI."

"Retrospectively, I would definitely recommend this product because of its functionalities, its reliability, and the good support."

"Juniper NetsScreen is a pretty straightforward firewall appliance which is certainly a good fit from mid-size organizations to big enterprises."

"The reporting needs to be improved. It is hard to get a domain."

"Kerio Control fulfills my needs completely and allows me to get on with my main work without spending any time on security or worrying about threats to the data I have."

"The most valuable features of Kerio Control are the IPS and traffic rules, the traffic rules are very user-friendly and the IPS is working well, and additionally, the anti-virus is effective with quick options, such as filtering."

"The statistic feature enables us to better use bandwidth management. We monitored the use by mobile, type of application, department, and by users. The bandwidth was solid. Our internet speed is optimized for our research."

"The most valuable feature is to provide users with the ability to log in to the portal page, keep track of their data usage and perform bandwidth management."

"Kerio has improved my organization's security."

"Now that we're both running fiber connections between Sydney and Adelaide, I can access our document server in Adelaide just from my PC, rather than using something like TeamViewer and transferring the file I'm after via TeamViewer from Adelaide."

"Out-of-the-box, the overall comprehensiveness of the security features is pretty good; it's not just a firewall, it's kind of a firewall proxy, reverse proxy, everything out-of-the-box sort of solution, and it's pretty comprehensive."

More KerioControl pros

Cons

"A lack of integration between our data centers."

"Security is a continuous process. In every product, there is a requirement for improvement. Its pricing should also be improved according to Indian market requirements. They must also improve on the reporting part. Its reporting can be more precise. If we can get a real-time report in a specific format, it will be helpful for customers to know about the current status of their security."

"Pricing for it is a bit high. It could be cheaper."

"We'd like to have multi-factor authentication via fiber."

"To stay ahead of the competition Fortinet FortiGate IPS needs to think about how to adjust pricing."

"To the best of my knowledge, Fortinet does not have a CASB solution and Fortinet does not have a Zero trust solution."

"The cloud management and automation capability could be improved."

"It's one of the more expensive brands."

More Fortinet FortiGate cons

"Features which could be improved include the search functions and the database size."

"The initial setup was quite complex."

"There has been some remote accessibility issues at times with older models."

"Kerio Control could improve by having higher availability and adding a mobile VPN channel. These additions are needed. The VPN is working fine on the Kerio Control but there needs to be a VPN client on the mobile phones, both for iOS and Android. This would be very good for us."

"Kerio Control could improve content filtering."

"Kerio Control has just improved on their biggest problem, which was to introduce better support for high-availability requirements in production."

"The product's technical support is not good as it used to be."

"It's too expensive. The license, in the last year or so, has gone up by over £100."

"After the takeover by GFI, one of the things that Kerio built was MyKerio environment. This has not been very reliable because I get many messages that MyKerio is not functioning. For some reason, there are things that they changed and it is not very reliable at this moment, instead I have to connect to the firewall to see what is happening."

"It has a VPN back to our data center but I don't think it has increased the number of VPN clients extended to those outside our environment"

"As of late, it seems that they can't release a version that doesn't have some type of bug."

Information not available

"The price is inexpensive."

"Its licensing is yearly. You renew every year. Its price is all-inclusive."

"There's a one-time fee. For KerioConnect, it's just a server. With KerioControl, you have an option. You can virtualize it on a VMware system or have the hardware. I think mid-range or desktop KerioControl hardware could cost around 2000 dollars for a 25 user client. You need annual renewal for additional features like antivirus."

"It is priced low enough for entry-level, but it has the power to grow with a company without them having to replace it."

"Search and compare."

"The pricing is in-line with our expectations in terms of the quality that we get for it."

"I pay approximately $50 for the solution on an annual basis."

"The biggest advice that I could probably give people is when you buy the solution be prepared to either buy the unlimited license or buy more licenses than you think. Each user license gives you one employee and each a user gives you five devices. In the world nowadays where everybody has a cellphone, tablet, desktop, and laptop, that's four devices. You still get one more device per person. That covers your servers and back-ends."
