Fortinet FortiGate vs. Imperva Web Application Firewall (WAF)

Fortinet FortiGate addressed an immediate security issue we had a few years ago. The device gave us a much clearer picture of the activities on our network and also more importantly, increased our awareness of threats from the internet as a whole. Fortinet FortiGate helps us to mitigate these threats with regular signature updates from Fortiguard labs, identifying certain characteristics which, once recognised by Fortinet FortiGate, can be harnessed to deploy powerful 'playbooks'.

I recommend Imperva specially if you have a big environment with thousand of websites because of its ease to use and availability. Imperva delivers a reliable solution with great capability to contain cyber attacks and even fraud preventions in some cases. The only scenario it's less appropriate is if your focus is anti fraud instead of a solution to block cyber attacks.

• SD-WAN - Load balancing of Internet traffic is a USP of Fortigate and makes it stand tall in the competition. Be it 3 or more Internet Links, multiple Subnets/segments of users to distribute and bandwidth load balancing for links and users. SLA based monitoring of Internet Links / MPLS links, makes it even better to choose the links on the basis of performance (Latency, packet loss, Jitter etc).
• SSL VPN configuration - As we all have WFH force (to some extend or all employee) during Covid-19, it is impossible to plan BCP without having a SSL VPN. In Fortigate, the SSL VPN configuration is very easy with the help of wizard. The deep CLI-level debugging is also very helpful in troubleshooting. Type of tunnel can be easily configured - Full Tunnel or Split Tunnel for SSL.
• Explicit Proxy - This is also a great feature to shape and re-route the traffic, configuring the Proxy on the Firewall itself. We are using this feature in Pilot for now, and planned to rollout in few weeks looking at the success rate of the POC.

• Block some dynamic attacks such as SQL injection.
• Block unfriendly accesses based on geographic source.
• Helps us implement SSL in cases where the original server can't (yet).

• Documentation is missing a great deal of detail and assumes the customer and just guess and fill in the blanks themselves
• Fortinet has lots and lots of video guides on topics that only a small percentage of customers would ever need
• The documentation and video guides do not get updated so most is only relevant to older software versions

• Attack Correlation Validation - This specific policy produces a lot of false positives as well as the SQL injection policies. Of course it is difficult to tell what a legitimate query is on a public facing web app.
• Profiling - I tend to spend more time than any other feature tuning the Web App Profiles. Plugins are used to help cope with this, but on extremely large web apps we are forced to turn off the profiling feature.

Fortinet's products have kept improving with new software releases and they continue to deliver great value. Their support is also very good. I believe that as a small enterprise, their products have given us competitive advantage delivering features and functionality that enable us to innovate and do things better. They also continue to be a leader in the markets they serve.

The firewall runs very well, firmware updates are fairly quick but you must follow the upgrade path. Neglecting this step will cause a lot of pain. If you decide to go with Fortinet FortiGate switches and/or access points, they can be managed within the firewall which is great. We're also using the FortiAnalyzer which easily plugs into the firewall for any reporting you may require.

It's easy and works great. The onboarding process, although easy, can sometimes take too long for SSL and domain validation, but its not a big deal.

The Support team at Fortinet is excellent. They can not only help you configure the device for what you are trying to do, they offer suggestions on improving rules, and troubleshooting issues. Their response time is fast, ensuring you are up and running immediately with no questions asked. We had a hard drive failure in one of our Fortinet Fortigate appliances. The tech answered immediately, and started rebuilding the drive after some preliminary investigations. After rebuilding, there were still errors and issues, so they dispatched a brand new Fortinet Fortigate appliance. The tech then backed up the configurations for when the new device came in, which showed up in a few hours. A restore of the configuration took less than a minute, and there were no more errors or issues.

We haven't needed support from Imperva since implementation. But during that time, their personnel were very quick to respond to questions. Since then, it's been largely doing its thing for us (which is exactly what we'd hoped).

I received it a couple years afters use it and it was just to confirm my knowledge about the tool.

[Fortinet] FortiGate is not only cost effective but it gives the comprehensive security against the APT attacks and gives the complete traffic visibility and granular control. You can easily create the VDOMs (Virtual firewall) within a Fortigate firewall and customize the dashboard as per your requirement if you have multiple VDOMs within a single firewall.

I believe there's no comparison as Imperva is a much more reliable and powerfull WAF. AWS WAF lacks of several features Imperva have and is not that simple to configure neither have a clean web console. I consider Imperva WAF a whole superior level of cyber security solution and it's consider to be one of the leader in this segment.

• The pricing given to us for our firewall was well within what we were already spending for other vendors solutions and had the added value of eliminating a separate expense for a dedicated web filtering appliance.
• We have also adopted Fortinet's security fabric approach and thus changed vendors for our switch and AP devices. These devices have come at reduced prices as compared to another previous vendor we were using, particularly in relation to ongoing annual maintenance costs.

• Meet compliance requirements - Check.
• Better Insight into web application - Absolutely great, checks all the traffic against RFC standards and will alert on common development mistakes that duplicate application traffic or provide attack vectors for potential attackers.
• Have had several issues blocking a customer without producing alerts, while it happened only one week out of 2 years of working with the devices, it did produce a lot of headaches.
