Cloudflare vs. Imperva Web Application Firewall (WAF)

Based on my experience, Cloudflare is well-suited for high-traffic websites and probably e-commerce platforms. Cloudflare can mitigate the risk of attacks on these websites using WAF and DNS protection mechanisms and provide cached content to the end-users quickly. The websites where it is not suitable are those that need high security and compliance requirements as Cloudflare might not meet all those criteria.

Imperva web application firewall does a great job in giving us control over access to our public web servers. With our regular hosting provider, we couldn't block access based on geography, or really anything. So we had to rely on traditional access controls to protect the data. But with the WAF, we can block countries such as North Korea, or we could stop any SQL Injection attempts, or even do a temporary block of IP in the case of detected brute-forcing.

• Registrar and DNS services are impeccable, with registrations done at cost and without ADs. DNS services setting standards for speed of resolution.
• DDOS protection. With their content distribution network to back them they have the bandwidth and tools to be both proactive and reactive to bad actors.
• WAF - Their Web Application Firewall helps mitigate common site vulnerabilities and has active zero-day protection running for breaking exploits

• Alert Aggregation - Correlates different violations into perceived correlated attacks.
• Ease of deployment - as one of the only WAFs that allow bridge mode deployment, this can be deployed with without downtime and no Network Architecture modifications. If the need for proxy is required at a later time, Transparent Reverse Proxy can be deployed within seconds and minimal configuration.
• Custom Policies - Custom security policies are easy to configure.
• Reporting - There are a good amount of pre-configured reports available by default.

• In some cases, using Cloudflare can actually lead to slower website speeds if the network is congested or if the website's traffic is particularly heavy.
• Some website owners may find that the level of customization offered by Cloudflare is limited, especially in comparison to other solutions.
• While Cloudflare is easy to set up and manage, it may be too complex for users who are not familiar with web technologies.

• The UI can use a little work (but is largely decent)

Everything is extremely concise and all settings apply immediately and take effect globally. There is no reason to explicitly plan/think in terms of individual regions as one would have to traditional cloud offerings (AWS, OCI, Azure). All Cloudflare products integrate seamless as part of a single pipeline that executes from request to response.

There are just a couple of points that are hard to find, that probably could be elsewhere. But these are minor; everything else is right where you'd expect it to be.

In 6+ years of relying on Cloudflare, I think we experienced one or two brief outages that were Cloudflare's fault.

Their Argo for the global network is the core feature we love.

I have only used their support a few times, and most times, they are responsive and able to resolve my issue with a minimal amount of time and effort. However, there was one instance where I simply asked about how to purchase some more resources (redirect rules), and I received some type of automated/AI response that was very unhelpful and gave me no opportunity to escalate to a person.

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).

Very well executed implementation where our team was able to handle the implementation with guidance.

They have the most generous free offering, and after the free offering limit is reached - you're still getting plenty of value for the buck.

They have very good reputation.

They have an ever expanding list of tools that can support multiple scenarios under one roof.

Ultimately, it was the easiest to work with that was still a "known" company (we've been burned too many times by up-and-comers). We needed something that gave us a lot of control but then didn't need its handheld on a daily basis. Imperva gives us a lot of that and we are still able to navigate it with ease.

They are built for scale and have the capacity to handle all the traffic we could ever expect to get.

• A lot of requests are cached and so egress costs from downstream providers are mitigated.
• DDoS protection has also managed to keep our site up and our cloud computing bill down.
• Setting up a proxy with a worker made putting various Google Cloud Functions running behind a single URL very easy and performant. Plus they offer API Shield on top of this.

• 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.
