# Running Sealights profilers alongside Contrast Security
When running SeaLights with Contrast Security, the configuration must be aligned with Contrast's implementation of profiler-chaining.
{% hint style="info" %}
Refer to Contrast Security .NET Agent documentation for more information:
* [Profiler chaining for the .NET Framework agent](https://docs.contrastsecurity.com/en/-net-framework-profiler-chaining.html)
* [Profiler chaining for the .NET Core agent](https://docs.contrastsecurity.com/en/-net-core-profiler-chaining.html)
{% endhint %}
## Pre-requisites for Contrast Security profiler chaining
* Have Contrast Security installed & configured as a profiler
* Have SeaLights installed & configured the required environment variables (see below)
## Configuring Contrast Security to run additional profilers
1. In the Contrast agent configuration YAML, the **enable\_chaining** property must be set to ‘**true.’**
2. Copy the following DLLs from the provided SeaLights installation to the folders specified below:
* **SL.DotNet.IpcLibrary-1.0.0.0\_x64.DLL** should be placed in **c:\Windows\System32**
* **SL.DotNet.IpcLibrary-1.0.0.0\_x86.DLL** should be placed in **c:\Windows\SysWow64**
3. Ensure the **`COR_PROFILER`** environment variable has the SeaLights profiler CLS ID: **`{01CA2C22-DC03-4FF5-8350-59E32A3536BA}`**
4. Once the above is completed and the service is restarted, it should start up with both profilers active.
5. If the profilers were chained successfully, 4 additional environment variables would appear with the **CONTRAST\_CCC** prefix:
* **`CONTRAST_CCC_COR_PROFILER`**
* **`CONTRAST_CCC_COR_PROFILER_PATH`**
* **`CONTRAST_CCC_COR_PROFILER_PATH_32`**
* **`CONTRAST_CCC_COR_PROFILER_PATH_64`**
### Standard SeaLights .NET Environment Variables
After installing the Sealights .Net agent locally on the environment, you need to apply the following environment variables to make it “registered” as a profiler. Please refer to the relevant configuration documentation page for accurate setup
{% code overflow="wrap" lineNumbers="true" %}
```
Cor_Enable_Profiling=1
Cor_Profiler={01CA2C22-DC03-4FF5-8350-59E32A3536BA}
COR_PROFILER_PATH_32=
COR_PROFILER_PATH_64=
```
{% endcode %}
