Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.

Enhanced network security with effective threat filtering and good bot managing features
We use Imperva DDoS protection to safeguard our network from multiple attacks. It is especially useful to protect websites or applications by redirecting traffic to eliminate threats Imperva DDoS increases our uptime to 99.99% by filtering and managing traffic to ensure only genuine traffic…

A solution requiring straightforward maintenance while remaining cost-effective compared to its competitors in the market
I am not in a position to speak about the areas where the solution needed improvement because I resigned during the implementation phase. At that time, the implementation was ongoing, and everything seemed to be going well. Using the solution, our team managed to transfer a couple of routers through a few areas. However, I believe the migration is still ongoing. Nonetheless, the first phase of the implementation was successful before my departure. There was a certain level of performance degradation in the solution, which I don't know if it can be tuned. This is because I was working for a short period on the solution. In my experience, it is an area that can be improved while also considering the stability and scalability aspects of the solution. If one wants to scale up, then one needs to change their plan. However, the thing is, one can always go for the larger scale based on one's anticipation of future traffic.

Quotes from Members

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

Pros

"It is a fast and secure DNS."
"It is a fast and secure DNS."
"The DDoS protection is the most valuable aspect of the solution."
"The most valuable feature is the web application firewall."
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."
"The most valuable feature of Cloudflare DNS is security."
"On the activity log, I can see the exact details, the visit, and the threat."
"The solution is very scalable. It is one of the most important features. You can also expand resources and features as well."
"The most valuable features for us are the DDoS and Bot."
"There is a quick switch between any of the the nodes if something goes wrong, where there's a there's an attack against a specific area. The security setup is reasonably easy. It's not a problem to do setups and rules and integrations. And, yeah, just the the back end team is also very willing to insist if there's questions that that we cannot answer or with these questions that we do have"
"The most valuable features of the Imperva Web Application Firewall are DDoS, malware, and the other malicious threat prevention it provides. Additionally, third-party integration is available. You can forward the log for further analysis."
"It blocks all types of attacks."
"I have had a positive experience with Imperva Web Application Firewall's tech support so far. They are knowledgeable and respond on time."
"There are quite a few useful Imperva Incapsula features. For example, one of them is the reports. The graphics are very good and it's easy to configure. The whole process is very fast and reliable too. They have good tech support as well."
"The managed service allows us to confidently rely on Nexusguard’s professional team to take relevant actions as and when required to make sure DDoS attacks are successfully mitigated, ensuring 100% uptime of our service."
"The support team was helpful."
"Cloud Diversion is another good feature packaged with the whole solution. When attack traffic is detected, Cloud Diversion triggers to automatically route our prefix to Nexusguard’s scrubbing center, ensuring that all attack traffic is dropped in the shortest time possible."
"Filters can be customized depending on the characteristics of the attack traffic. This feature has made it easier for Nexusguard's SOC team to further isolate any specific attack that can't be blocked by pre-configured mitigation."
"Based on the support received for implementation, I rate the solution's technical support a nine out of ten."
 

Cons

"There might be helpful if there was some web application firewall feature."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."
"It should confirm audit findings of the assigned area with auditees to ensure that the audit conclusions are based on an accurate understanding of the issues."
"The pricing could be improved."
"There should be a specific price list for enterprise-level customers."
"I loved the approach of the cloud. The cloud has a lot of new features, like advanced web protection and DDoS protection. If those could also be on-boarded onto the on-prem versions, that would be ideal. They need to pay attention to both deployment options and not just favor one."
"There’s nothing that’s missing in terms of features."
"I would like to improve the tool's turnaround time in terms of support."
"Imperva Web Application Firewall is a good system, but we found that the visibility of the diverse-path server, e.g. where the traffic is coming from, the different IPs, etc., needs improvement."
"The signature updates could be faster. Sometimes we have to upload signatures to the Imperva portal for checking and analysis before we can use them."
"Imperva Web Application Firewall is very expensive."
"There's always room for improvement. Occasionally, there might be false-positive alerts."
"The user interface could be better."
"One thing that we would like to improve from them is to provide more training to SOC team for them to have a deep understanding of the solution so that they would always be ready to answer anything without the need to escalate queries to senior personnel."
"The solution must provide features for the post-processing of the traffic type and the traffic quality."
"One of the features that should be added to the next release is report generation. Currently, reports can be downloaded every month and are only available at the beginning of each month. It would be nice to generate the reports based on specific dates that we prefer and not have to wait until the next month for the current month’s report."
"There was a certain level of performance degradation in the solution, which I don't know if it can be tuned...In my experience, it is an area that can be improved while also considering the stability and scalability aspects of the solution."
"The mitigation scope of Origin Protection is not fully efficient as there could be delays in activating the countermeasures."
