Enterprise Web Protection
Incapsula vs cloudflare
Some organizations require strong web protection (DNS diversion), but can do without infrastructure protection (BGP diversion) or a physical appliance. This will be the case when the DDoS threat and/or the potential damage are not considered critical enough to justify the extra investment.
For such requirements, CloudFlare and Incapsula provide solutions that also include acceleration built into the DDoS service.
Deployment & Service Options
With cloud based service, both CloudFlare and Incpasula offer basic web protection (DNS) and network protection (BGP). They both provide free tiered services, services for SMBs and for Enterprises.
CloudFlare offers 86 POPs vs. Incapsula with only 30, But the effect of this on DDoS mitigation is only indirect (see Number of Data Center).
If your organization has a non-web service like a proprietary protocol, then only Incapsula can serve you with its latest IP Protection topology.

Incapsula vs. CloudFlare – Deployment
Mitigation
Web proxy and caching
Both vendors have web proxy with caching capabilities. This may not be the most sophisticated technology yet it is the most effective and will succeed blocking many attacks. However, today’s attackers are persistent and will find ways to pass this mitigation. Foremost by attacking dynamic pages.
Web Challenges
This leads us to the next most significant mitigation – web challenges. Ideally we want the vendor to provide all the challenge spectrum (read more). Incapsula offers 4 out of the 5 challenges. The only one that is missing is the modern CAPTCHA, and in the unlikely event that its JS challenge will not be effective it would have been slightly better to have this. CloudFlare offers only two out of the five challenges. It is not that they will not be able to stop DDoS attacks, it is only that you will need to use a bigger hammer than you intended. CloudFlare does not have plain Cookie Validation, and in most cases this will be enough to stop the attack with minimal impact to legitimate users and legitimate bots. CloudFlare also does not have Silent Human Investigation and in the case of a JS passing bot (e.g. PhantomJS), you will be forced to escalate to the intrusive modern CAPTCHA. The traditional CAPTCHA is also not used by CloudFlare, but since they have the modern version this is reasonable. Another annoying thing is that CloudFlare JS challenge is visible to the user.
Signatures
Both vendors offer signature and customer signatures options. CloudFlare is better at the vendor signature as it provides visibility to the signature name and allows the user to control its action, while with Incapsula it is a black-box service. In user signatures Incapsula is better with its excellent pre-IncapRules language allowing even beginners to compose meaningful signatures. CloudFlare takes a different approach – you write in plain English what you want the signature to do and submit. CloudFlare’s support writes the signature for you, which means you will not be able to review it or change its action.

Incapsula vs. CloudFlare – Mitigation
Rate Limit
In Rate Limit CloudFlare has a large and important gap. While usually it is not recommended to stop attacks with Rate Limit technologies that eventually can also “rate-limit” legitimate users, in some scenarios it is still important, such as to protect mobile APIs. Challenges are not good as they often cannot be used with RESTful API, and Rate Limit can be your only savior.
Network Protection
Incapsula Network Protection (BGP) is a black-box. You cannot configure or understand what actions are taking place and how effective they are. No information could be received from CloudFlare on this issue.
CloudFlare Web Challenge
UX and Reporting
User Experience (UX) is important as it determines how much of the existing functionality you will utilize, how quickly you will understand a security event, and how quickly you can respond while under attack.
In UX per se, the difference between the vendors is not dramatic. Incapsula look-and-feel is really excellent and CloudFlare is somewhat old school relative to cloud services. Nevertheless it is still very easy to navigate and find the function you need with both vendors.
Security Configuration
Both vendors’ security configuration is good and the limitation of each vendor in using signatures has been covered earlier. One disturbing element with CloudFlare is the ability to independently block a URL – probably the most basic thing you can ask from a WAF. This can be done, but it is a full-service feature. Why not provide a simple interface just like the one provided for blocking an IP or a country?
Real-time monitoring
We did not have access to CloudFlare’s real-time monitoring (RTM). Incapsula’s RTM, which we did a review, is great. It is granular and shows well allowed versus blocked traffic. It took about 15 seconds for traffic to appear, which is an excellent performance for a cloud service with distributed POPs.
You can consume the security events generated by Incapsula in several ways – on their portal, by receiving an email, via a syslog, and when under attack they will also call you. CloudFlare displays events on their portal and will call you in the case of a severe attack. It lacks a push notification method and offers no email or syslog options. CloudFlare does offer a REST API to pull the alerts. But it is unlikely that everyone would like to implement a REST client to know what is going their network.

CloudFlare and Incapsula like most vendors out there, do not provide official pricing for their Enterprise service, and the only way to retrieve it is to request a quote.

CloudFlare vs. Incapsula – UX & Reporting

CloudFlare and Incapsula, like most vendors, do not provide official pricing for their Enterprise service; the only way to retrieve this information is to request a quote.
| SMB Pricing | SMB Pricing is covered in the SMBs – CloudFlare Business vs Incapsula Business section. |
Bottom Line
If we are taking the liberty to compare the vendors from a higher ground, observing the entire portfolio, it seems that CloudFlare targets a much wider audience. It offers numerous services, operates in an application market, and appeals to the multiple needs of different organizations, especially SMBs. Incapsula offers fewer services, but they seem to be more complete and focused.
From the narrow DDoS point of view, both services are mature; choosing either of them to protect your service from DDoS attacks would be a good option. However, Incapsula’s service is more complete than CloudFlare’s in all the categories reviewed. Put differently, if you need only DDoS protection and you receive the same quote, Incapsula has a clear advantage.
