Filtration mode rule¶
The filtration mode allows you to enable and disable the blocking of requests to various parts of a web application.
To set a filtration mode, create a Set filtration mode rule and select the appropriate mode.
The filtration mode can take one of the following values:
default: the system will work in accordance with the parameters specified in the NGINX configuration files.
off: the analysis and filtration of requests are disabled completely.
monitoring: the requests are analyzed and displayed in the interface but they are not blocked.
blocking: malicious requests are blocked and displayed in the interface.
To implement this rule, the NGINX configuration files must permit centralized management of the operation mode.
Default instance of rule¶
Wallarm automatically creates the instance of the
Set filtration mode rule on the default level. The system sets its value on the basis of general filtration mode setting.
This instance of the rule cannot be deleted. To change its value, modify general filtration mode setting of the system.
As all the other default rules, the
Set filtration mode default rule is inherited by all branches.

new user registration is available at example.com/signup
it is better to overlook an attack than to lose a customer
Then, to create a rule disabling blocking during user registration
- Go to the Rules tab
- Find the branch for
example.com/signup, and click Add rule
- Choose Set filtration mode
