We’re pleased to announce a new version of Imunify360. Version 6.5 is now available. The following features are new in the v6.5 release:

• WebShield improvement
  In this release, we present a new and improved WebShield. Starting from version 6.5, WebShield will work faster and consume even fewer resources. We improve performance by running WebShield as a pure Nginx module.

• Language support for SplashScreen
  Version 6.5 broadens the set of languages supported by our SplashScreen. 

Lightweight WebShield 

Meet the new, completely reworked and re-imagined WebShield! From now on the performance of WebShield will be greatly increased. 

As a rule, we constantly research and explore ways to better our solutions. For version 6.5, we came up with the idea of discarding OpenResty usage as a platform for WebShield. The decision was made to implement it as a module for pure Nginx in conjunction with Go daemon. We rewrote the Lua algorithms of WebShield as a lightweight C-module and performed a number of other technical optimizations to achieve superior performance for WebShield.

This feature will be enabled by default for all customers and doesn’t require any manual setup.

To summarize, these improvements free up to 100MB of RAM. On the other hand they open a door for another improvement coming in future Imunify360 versions: embed WebShield’s module into the existing front-end Nginx proxy (if available) and free up more resources by eliminating separate Nginx instance.

Language support for SplashScreen 

Anti-bot protection was introduced in v.5.6. Since then we have received requests to translate the JavaScript challenge messaging. From now on the SplashScreen messaging will be aligned with languages supported in the WebShield. 

The following languages will now be supported: Arabic, Danish, German, Greek, Spanish, Farsi, French, Hebrew, Hungarian, Indonesian, Italian, Malaysian, Dutch, Norwegian, Polish, Portuguese, Romanian, Swedish, Turkish and Chinese. These modifications may provide help in resolving JavaScript issues website users may face in some rare cases.

The language for SplashScreen messaging is defined by the locale of the browser and follows the Accept-Language HTTP header.
