Features and Benefits:

Web Application Firewall

Web Application Firewall

Analyze Website traffic to systematically identify and block Web application attacks

The days when companies could rely on traditional firewalls to protect their Websites from hackers are over. In today's online environment, Websites require more comprehensive security measures to ensure they remain unaffected by cyber-attacks and available for business. Without an appropriate solution in place, your website may be at risk of attack.

Incapsula includes a cloud-based Web application firewall which blocks Web attacks before they can harm your Website. By routing your Website's traffic through our system, we ensure that bad traffic is filtered out, and good traffic continues to flow through to your Website.

Our threat detection models were developed with Imperva's vast experience, gained over the past ten years leading the Web application firewall market. As traffic passes through our network, it is automatically analyzed to identify and block Web application attacks such as Cross Site Scripting (XSS), SQL Injection, Resource Injection, and other OWASP Top 10 threats.

Setup is simple and does not require customers to install any hardware or software, or alter Web applications; this allows even small and medium businesses with limited IT and security resources to enjoy best-of-breed protection for their business.

Incapsula protects Websites against known and emerging threats including:
  • SQL Injection
  • Cross Site Scripting (XSS)
  • Illegal Resource Access
  • Remote File Inclusion
  • Comment Spam
  • OWASP Top 10 Vulnerabilities
DDoS Attack Mitigation

DDoS Attack Mitigation

Automatically detect and block advanced DDoS attacks up to 8Gbps

Incapsula delivers complete defense from all types of DDoS attacks, ensuring that even the most advanced DDoS attacks are unable to affect your Website's availability. With up to 8Gbps of DDoS attack protection; you can be assured that your web applications are always accessible.

DDoS attacks can broadly be classified into two types – network attacks and application attacks. Network DDoS attacks, flood network resources with excessive requests to overwhelm devices at the network level. Application DDoS attacks aim to overwhelm Web servers, application servers, or database resources by either flooding a Web application with legitimate requests or by exploiting business logic flaws.

Incapsula delivers defense for both network and application level DDoS attacks. Network Level DDoS attacks are automatically filtered out of Web traffic as it passes through our cloud-network. Application level DDoS attacks are stopped by our user profiling and classification engine that identifies and blocks automated threats such as DDoS bots, thereby preventing their DDoS attacks from reaching your Website.

Incapsula Key Benefits
  • Effectively mitigates application and network level DDoS attacks
  • Protects in minutes with effortless deployment
  • Saves costs related over-provisioning bandwidth
Backdoor Shell Protection

Backdoor Shell Protection

Detect and block Website backdoors installed by hackers

Incapsula helps detect and block any attempt by hackers to install or operate a backdoor on your Website. By analyzing your Website traffic for signs of a backdoor, Incapsula is able to quickly detect and block backdoors, as well as pinpoint their exact location on your system so you can easily remove it.

User Profiling and Classification Engine

User Profiling and Classification Engine

Differentiate human users from automated threats and block bad bots

Research shows that an average of 50% of all Website traffic is non-human. Incapsula improves Website security, lowers Web server utilization and reduces bandwidth consumption by identifying and blocking all automated threats and “bad-bots.”

As users visit your Website, our system's user classification engine profiles them in real-time to identify each user's purpose of visit and determines whether they are human or automated users. Legitimate traffic, including human users and “good bots” such as Google's search-engine bots will be granted access to your site, while “bad-bots” will be blocked or challenged with a CAPTCHA test.

Incapsula blocks unwanted bots, including:
  • Site scrapers
  • Comment spammers
  • Fake registrations
  • DDoS attack bots
  • Vulnerability scanners


Global Content Delivery Network

Global Content Delivery Network

Speed up your Website by serving content from local data centers near your visitors

Our cloud solutions help improve Website responsiveness and reduce bandwidth consumption by utilizing a state-of-the-art content delivery network (CDN), which is built on a network of high-powered data centers strategically positioned throughout the globe. Our CDN automatically caches and serves your Website content from each of our data centers, eliminating bottlenecks at central servers and ensuring that your visitors are receiving content from the data center with the closest proximity to their geographical location.

Dynamic Content Caching

Dynamic Content Caching

Reduce Website bandwidth consumption by dynamically caching Web content

Incapsula features content caching for both static and dynamic content, resulting in faster webpage load times, reduced server utilization and lower bandwidth consumption for your Website. These caching techniques help maximize the performance gains available to your website. Static content, such as HTML files, images or JavaScript are cached, allowing them to be served to visitors directly from our datacenters. Dynamically generated content is also cached while it remains valid and unchanged.

Web Content Optimization

Web Content Optimization

Decrease Web page load times by compressing, optimizing, and minifying content

Our system automatically optimizes Website content and traffic as it passes through our network to speed up Website responsiveness and reduce the amount of unnecessary or redundant data being sent between your Website and its visitors. Optimization techniques include content compression session optimization and content minification.

Compliance and Reporting

PCI DSS Reporting

PCI DSS Reporting

Fulfill PCI DSS 6.6 compliance with simple, automated PCI reporting capability

Any Website that processes credit card payments is required to adhere to the Payment Card Industry Data Security Standard (PCI DSS) 6.6. This requirement stipulates that all Web applications must either deploy a WAF or conduct manual code review.

Incapsula is the simplest and most cost effective way to ensure PCI DSS 6.6 compliance and the only Level 1 PCI-certified cloud-based Web application firewall solution for midsized businesses. Incapsula is easy to implement and provides continuous protection without impacting the Web development process, requiring in-house PCI expertise or involving PCI consulting projects.

Website Traffic Analytics

Website Traffic Analytics

Gain powerful insight with Web site traffic analytics

Our unique analytics dashboard gives you detailed insight into your Website visitors, performance statistics, and security events that are not available from other analytics programs.

Many Website owners assume that the vast majority of their Web traffic is made up of human users. In reality, as much as 50% of Web traffic can originate from automated clients such as bots. We have adapted our analytics to include automated sources, giving you a more accurate representation of your site's traffic. Reports include statistics on visitor types (human vs. bot), country of origin, client applications, requests per second, and bandwidth consumption levels.

Our analytics provide detailed threat and security data that helps you decide who should be allowed to access your site and who should be blacklisted. You can also track your Website's performance analytics to monitor how our cloud platform is accelerating your web site, and saving you money by reducing bandwidth consumption.

Frequently Asked Questions:


Which plan is right for my business?

Start by determining the amount of bandwidth used by your Website. Incapsula plans are structured based on the amount of bandwidth a website uses (as measured in MBps). If you wish to protect multiple websites, you will need to find the aggregate bandwidth usage for all of the Websites. Determining the bandwidth usage of your website can usually be accomplished by contacting your website administrator or hosting company. If you are unsure or unable to determine how much bandwidth you need just let us know, we can help!

When will I move up to the next plan?

There is no need to move up to the next plan until your bandwidth requirement changes. If you start to exceed your subscription plan's bandwidth capacity, we will give you the option to pay an overage fee or upgrade to a larger plan.

How often will I be billed?

Imperva Incapsula plans are sold as a yearly subscription. You will be billed annually for your subscription.

I already have a firewall, do I still need this service?

Firewalls and Next Generation Firewalls do not adequately defend against http/https-based attacks launched at Web applications. Deploying a WAF in addition to existing firewalls provides Web applications a way to inspect http/https traffic and block advanced Web attacks like SQL injection, Buffer Overflow, or Cross-Site Scripting (XSS).

Moreover, firewalls are also not designed to stop DDoS attacks. When firewalls are used to block DDoS attacks, these devices are frequently overpowered by the volume of requests that they must process; turning them into a single point of failure between Website visitors and the Web server.

My hosting provider provides security services for me. Would I still benefit from using these services?

Many hosting companies provide basic security precautions for their customers, although it is frequently limited to a traditional firewall or IDS/IPS. This is not enough to adequately protect Websites from Web application layer attacks or DDoS attacks. Incapsula makes a perfect complement to the security services offered by your hosting company by extending your security into the application layer to block attacks like SQL injection and Cross Site Scripting (XSS).

Does this service support and protect SSL traffic?

Yes. Incapsula supports and protect SSL Traffic. We can issue an SSL certificate for you or make use of your existing certificate.

Do I need to adjust my local firewall settings?

We suggest that you configure your firewall to permit external traffic from the following IP addresses. Once all changes are in place and your domain is safeguarded by Incapsula, you should allow traffic from these IP addresses only. This prevents malicious traffic from bypassing Incapsula and directly attacking your Website.
