Incapsula provides a robust web application security experience, which also comes with advanced analytics tools. The PCI-certified web application firewall makes sure that you are protected at all times against any type of application level attacks. The WAF is customizable, which means that you can apply your own security policy within the WAF by setting custom security rules. The system’s advanced client classification tool is able to distinguish between good and bad bot traffic, thereby allowing you to block web scrapers, protect against spam comments and other such systems that may overload your servers. The two-factor authentication with single-click implementation streamlines the management of multiple logins across multiple websites, secures administrative access as well as remote access, and allows you to implement access restrictions to several websites.

CDN (Content Delivery Network)

Incapsula makes use of the capabilities of a content delivery network to optimize website performance by identifying all cacheable content, including dynamic content, and makes use of dynamic profiling and frequency analysis tools to identify the most frequently accessed resources and serve them from memory. The intelligent application-aware CDN is capable of profiling usage patterns and website resources, all the while making sure that users receive up-to-date content.

Apart from content caching, Incapsula enhances user experience by making use of other tools like content minification, image and file compression, session optimization, TCP optimization and connection pre-pooling. The results are an accelerated page rendering and minimal latency.

DDoS Protection

Incapsula provides protection against all types of DDoS attacks whether these occur on a network level or on an application level. Its transparent mitigation entails 0.1% false positives and doesn’t interfere with the normal user experience. The system’s ability to automatically differentiate between veritable visitors (search engine and humans) and malicious bots, and its immediate triggering ensures a high level of protection.

DNS targeted attacks are handled by re-directing all DNS queries to the Incapsula cloud for analysis and cleansing, thus, only queries that are deemed safe reach your origin DNS server. The system takes things a step further by also preventing the use of your DNS server as a platform for DNS amplification attacks against others.

Load Balancer

Incapsula’s global CDN ensures optimal resource utilization by monitoring and understanding traffic to your servers. Real-time monitoring allows the automatic detection and elimination of outages and downtimes. The system further allows you to detect server traffic imbalances and to take proactive measures to handle potential problems before they cause any disruptions.

In the event of an outage, in order to accelerate disaster recovery, Incapsula supports automatic failover between active and standby servers. Companies with multiple data centers can make use of Incapsula’s Global Server Load Balancing (GSLB), which can route traffic to a given data center based on a user’s geographical location by applying either the Best Connection Time or the Geo-Targeting method.

Real-time health monitoring and alert system ensure you stay on top of any security or performance problem that your website may be facing.
