Pro Great value for the price
For a full ADC package Incapsula comes in at 4k a month, compared to Akami's 13-14k, it is quite the bargain.
Pro Intelligently recognizes bots to counter layer 7 attacks
Incapsula has a bot recognition engine to achieve a low rate of false positives on layer 7 attacks. These attacks are notoriously hard to detect as they are designed to look like regular network traffic.
Their always-on recognition solution automatically triggers layer 7 protection without user intervention, protecting you during downtimes like holidays, weekends, and late nights.
Pro Instant propagation of security rules
Rules configured through IncapRules are able to instantly propagate to Incapsula's reverse proxy based global network. This is in contrast to DNS based systems that are subject to TTL/DNS cache delays, which slow down the propagation of custom security rules.
Pro Real time dashboard
Incapsula provides a dashboard that shows traffic data in real time, allowing you to respond to threats immediately as they happen, and see the results of your response as quickly as possible.
Pro Powerful security rule scripting through IncapRules
IncapRules is a full fledged scripting language that gives clients full and detailed control of security policies. The language provides access to dozens of filters for analyzing incoming traffic, including headers, client type, location, access rates, and more. There are also a multitude of trigger responses on how to deal with the filtered traffic, including alerts, captchas, and blocking.
Pro Protects non-web assets
Incapsula has an extra layer of DDoS protection that also protects subnet network infrastructure, like FTP and email.
Pro 24x7 chat support
Incapsula chat support is always available. Chat can be much easier to use than phone support, as you can easily copy and paste technical data through text, and get instant feedback you don't get through email.
Pro Massive network capacity
Incapsula's proprietary "Behemoth" machines handle 170 Gbps each, and process up to 100 million packets per second. As of March 10th 2015, they have a network of 13 data centers with these machines, allowing them to process more than 2 Tbps of bandwidth on top of their existing capabilities.
Con Unreasonable anti-spam policy
Not suitable if you have an association with online advertising. A single email that may include your domain that appears on Spamcop will result in a threat to terminate your account and a requirement to disable the URL -- even if you are not responsible for the production or sending of the email.
Con Config changes take 5-10 minutes
Any config change is queued for several minutes before being applied, without any time estimate. Combined with caching and DNS delays, it can make debugging a bit more difficult.
Con Scripting language and rules for IncapRules has steep learning curve
While there is a rules editor that offers a shortcut into rule definition, the learning curve to master how to utilize in full IncapRules is pretty steep.
Con Enterprise package pricing not listed
Potential enterprise customers will need to call Incapsula to find out the pricing for their enterprise plans as they are not listed on the site and appear to be priced on a case by case basis.
