Imperva

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.

Citrix

Citrix Netscaler can be a powerful network appliance for environments that are fully committed and open to utilizing a network appliance that isn't made by a traditional network vendor. Administrator user experience has improved over the years and will continue to improve with the flexibility of virtual and physical appliances available for medium and large enterprises.

Pros

Imperva

  • 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.

Citrix

  • Flexibility. NetScaler assumes its admins know a bit about networking and in-depth details surrounding the applications they are configuring access for/to. This being so, the range of configuration options is very broad allowing various versions' combinations of protocol patterns, expressions, rules etc., all to the benefit of the admin.
  • Granularity. Having such a broad range of configuration options available, while still allowing simple options to be configured simply. The GUI is well-stylized and navigation has a good flow.
  • Ease of control. For load-balancing of simple services right out of the box, NetScaler makes it pretty easy, compared to the range of options available in the surrounding GUI and under the hood.

Cons

Imperva

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

Citrix

  • The documentation could use an overhaul with specific examples related to the command line as well as GUI. Explanations in the documentation would also be helpful.
  • Being able to have more than just one routing table would allow the ability to leverage security.

      Usability

      Imperva

      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.

      Citrix

      Improve on the specifics I mentioned previously and could be a 10/10 product. It is also a confusingly branded product that I have supported in two large enterprises where IT departments are unsure if the product belongs to the Citrix remote access support team or the Network infrastructure support team (it should be the later) and typically under utilized.

      Support Rating

      Imperva

      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).

      Citrix

      Overall, our organization's experience with Citrix support is that support can be hit or miss. Oftentimes it takes multiple attempts and much longer than desirable to obtain a viable solution for issues experienced with their products. It would be great to see Citrix invest time, effort, and almighty dollars into improving their support and bug fix process across the board.

      Alternatives Considered

      Imperva

      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.

      Citrix

      We chose Citrix ADC over Kemp and F5 due to additional integrations with various products such as Citrix/Horizon/Monitoring tools. We additionally chose ADC due to better ease of use and ability to have the appliances be virtual or physical, with the configuration being a simple migration of code which provided flexibility to be able to do a hybrid environment with ease.

      Return on Investment

      Imperva

      • 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.

      Citrix

      • It has saved a tremendous amount of money and manpower by allowing for broad support without the need for a VPN.
      • The security functions within Netscaler enabled our business to pass additional IT-based audits.
      • Having a full Citrix stack from front to back makes our business look more professional both to our users and outsiders.
