# IT Onboarding at Honestly: Technical Requirements & Best Practices

> Technical setup guide for IT teams: email whitelisting, optional SSO, and HCM integrations to ensure Honestly runs reliably across your organization.

To ensure Honestly runs smoothly in your organization, a few technical setup steps are required.

This article is intended for **IT teams** and provides a clear overview of the recommended and optional configurations needed for a successful setup.

***

### Overview: Required Setup Steps

| Step                 | Requirement       |
| -------------------- | ----------------- |
| Email whitelisting   | Yes (recommended) |
| Single Sign-On (SSO) | Optional          |
| HCM integration      | Depends on setup  |

***

### 1. Email Whitelisting (Recommended)

To ensure that **survey invitations and reminders** from Honestly reach all employees, we recommend setting up email whitelisting in your email infrastructure.

### Please whitelist the following:

**IP address**\
87.253.239.34

**Sender email address**\
[kontakt@honestlymail.de](mailto:kontakt@honestlymail.de)

This helps prevent survey emails from being blocked or filtered as spam.

***

### 2. Set Up Single Sign-On (SSO) (Optional\*)

\***Note:** SSO is included by default in the **Enterprise** plan. If you are on the **Team** or **Business** plan and would like to use SSO, it can be purchased as an additional add-on.

Honestly supports **Single Sign-On (SSO)** , allowing employees to log in using their existing company credentials.

### Supported standards & systems

* SAML 2.0
* Azure Active Directory

SSO is optional but provides additional convenience and enhanced security.

### 3. Synchronizing Employee Data (HCM Integration)

To keep employee data up to date automatically, Honestly offers several integration options depending on your HR system.

***

#### 3.1 Personio

If you use **Personio** , you can take advantage of our **native Personio integration** to keep your employee data synchronized.

Guide:\
[Personio & Honestly – Employee Sync](/help/integrations/personio-employee-upload)

***

#### 3.2 Other HCM Systems (e.g. Factorial, Deel, HiBob)

For many other HR systems, Honestly offers native integrations via our partner **Kombo**.

Supported systems:\
[Kombo Integrations](https://www.kombo.dev/integrations?integrationcategory=HRIS)

***

#### 3.3 CSV Integration (Roles & Permissions)

\***Note:** This option is included by default in the **Enterprise** plan. If you are on the **Team** or **Business** plan and would like to use it, it can be purchased as an additional add-on.

If you need to synchronize **roles and permission attributes** in addition to basic employee data, we recommend using the **CSV integration**.

**Important:**\
Personio and Kombo integrations **do not sync roles or permissions**.

With the CSV integration, you can define:

* User roles (Admin, Manager, Analyst, Report Viewer)
* Permission attributes for data access (e.g. business unit, location, department)
