Offers a huge signature repository and is superiorly effective in mitigating DDoS attacks
The solution's learning curve can still be further reduced, which presently stands at two or three months. The product has a custom rule set that users can modify and manifest as needed. The vendor can probably shorten the learning curve using cutting-edge technologies like AI. The solution provider can also work around the web applications and identify the toolset that needs to be implemented to deploy the solution in less time. The vendor has launched a SASE product that can function with Cloudflare Web Application Firewall, but many improvements are needed in terms of features, such as the web filtering feature, and CASB has not yet been added.

Provide DDoS protection and better security at effective rate
It is expanding its number of data centers for scrubbing traffic. Currently, there is only one POP for cleaning in South Africa. They might add another POP in North Africa, possibly in Nigeria or Egypt. Latency concerns customers, especially in regions like East and West Africa, where traffic has to travel to South Africa before returning. Increasing the number of POPs across the continent would help address these latency issues and improve overall service. While the platform is already quite strong, there’s always room for improvement, especially in keeping up with emerging trends and new types of attacks. Enhancing security capabilities could be beneficial. Integrating more advanced AI features could significantly improve its effectiveness and help customers leverage these tools more effectively. It would be great to see more focus on AI integration to handle and analyze data more efficiently.

Offers Application Protection Against Web Attacks
There is a need for expanded licensing terms and options. There's also a need for improved and more agile customization features. The user needs to be able to manage each policy as required; the functionality needs to empower the user. There should be a complete suite of desktop provider policies available to users. Overall, it needs to be more user-friendly.

Quotes from Members

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

Pros

"There is a huge signature repository"
"It is a SaaS solution unlike much of the competition."
"Cloudflare is cheaper compared to Azure WAF, which I have considered before."
"The product has a valuable security control functionality."
"It's pretty convenient and pretty easy to set up and run. And then kind of for static content, it also offers caching."
"The initial setup process is simple."
"The product has improved our security posture by blocking bad actors."
"The integration of Cloudflare with Cloud Suite is its most valuable feature."
"It fits our requirements, as well as our budget."
"It is a stable solution."
"An improvement has been to our website: It increases the speed of our response, the capacity of the site, and optimizes the bandwidth.​"
"The most valuable features for us are the DDoS and Bot."
"On the activity log, I can see the exact details, the visit, and the threat."
"Imperva DDoS helps us automate production. The client had specific requirements for a cloud project in the financial sector."
"They're quite easy to install and quite easy to set up. Clients really like that. Especially when you're dealing with the cloud, it's really easy."
"The technical support is excellent."
"Since we are using this tool for protection purposes we really appreciate the hybrid security abilities; the main idea here is that we powerful protection our application needs."
 

Cons

"We have noticed some latency when the call goes through the firewall. That could be improved."
"Cloudflare Web Application Firewall should include port forwarding features."
"The blocked logs are difficult to read at times."
"A key challenge arises when dealing with numerous integrations with HVAC systems. Depending on the specifics, there might be some configuration mismatches, which necessitate specific support."
"The dashboard could be more user-friendly."
"The product can improve by having more multitenancy capability, which is currently not available."
"The platform's control features related to real-time authentication and response time need improvement."
"I have experienced some difficulties with Cloudflare's support as a customer based in India."
"It would be better if we were able to manage and apply changes to multiple websites/web applications, and search WAF logs for multiple websites, via the Incapsula dashboard."
"A limited tool if you're looking to customize."
"The weakest point of Imperva is their first level of support, which should be improved. They should also improve the access and security logs viewing directly on the portal. I would like to see better access and security logs through the portal and not only through a SIM solution. Currently, if you want to explore your access and security logs from Imperva, you need a SIM tool or a SIM infrastructure on your side to do it. You can't do it manually or directly through the portal, which is a big problem for us. I had a call yesterday with Imperva for the roadmap, and I just told them this. They agreed that this is an improvement point from their side."
"The solution needs to improve Integration with third parties for their on-prem deployment models. The integration is not that good yet."
"Imperva should have more points of presence in Africa."
"The salespeople tend to exaggerate its capabilities, which can cost you money if you don't verify the information."
"Pricing can be improved, as it is quite expensive."
"I am not sure if this application has a policy where you can create your custom policy and run it as our firewall. We should have some ability to also create some custom policy, then run it as a firewall."
"There is a need for expanded licensing terms and options. There's also a need for improved and more agile customization features. The user needs to be able to manage each policy as required; the functionality needs to empower the user. There should be a complete suite of desktop provider policies available to users. Overall, it needs to be more user-friendly."
 

Pricing and Cost Advice

"The annual licensing fee is $10,000 USD."
"What's my experience with pricing, setup cost, and licensing? I believe the pricing is not the best, but it's reasonable and acceptable. We also use the McAfee system in parallel. In terms of pricing, its okay - not great, but not bad either. It falls in the middle, which is acceptable. In terms of support licensing, last time, we were searching for a solution, and we considered products from resellers rather than directly from the cloud provider. However, the pricing we encountered was exceptionally high. As a result, we are inclined to select support from the reseller."
"The solution is expensive."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"The solution's pricing option needs to be more transparent for enterprise clients."
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"It starts at $20 and can easily go up to $200 monthly"
"The license is on a yearly basis."
"Imperva charges us based on bandwidth, which is better than other vendors that charge us according to data transfer."
"The cost is somewhere around $10,000 a site. For every site, you pay individually. For every DNS entry, you have you pay."
"​Although the pricing can be a little high, it is worth the protection and security that it offers.​"
"Pricing could be more competitive."
"We have an issue with Imperva Incapsula in the Iraqi market because of the high price."
"The cost is on par with other solutions such as Cloudflare and Akamai."
"The data packages are higher than our needs so we end up paying for data that we don't use."
