Getting started with LetzSecure

Welcome to LetzSecure! This guide will walk you through the essential steps to configure your account and launch your first AI-powered phishing campaign. By following these steps in order, you'll ensure accurate testing and get the most out of the platform.

The Setup Process:

  1. 1
    Verify Your Domain: First, you must prove you own your company's domain (e.g., yourcompany.com). This is a critical, one-time security step that authorizes you to conduct simulations.
  2. 2
    Whitelist Our Servers: Next, you'll configure your email system to accept our simulation emails, ensuring they reach your employees' inboxes and aren't flagged as spam.
  3. 3
    Import Your Employees: Add the employees you wish to train and test. You can add them individually or upload a list.
  4. 4
    Launch Your First Campaign: With the setup complete, you're ready to create and launch your first AI-generated simulation.

Domain verification

Domain verification is a mandatory security measure that proves you have the authority to send simulations to email addresses at your domain. This is a one-time process for each domain you wish to use.

STEP 1 Add Your Domain

  1. • In your LetzSecure dashboard, navigate to Settings > Domains.
  2. • Click the + Add Domain button.
  3. • Enter the domain you wish to verify (e.g., yourcompany.com) and click Next.
  4. • You will now be presented with two verification methods. Choose one of the options below.
Recommended

Method A: DNS Record

This is the most reliable method. You will need access to your domain's DNS provider (e.g., GoDaddy, Cloudflare).

  1. Select the DNS Method: In the verification window, choose the DNS method to reveal your unique TXT record.
  2. Copy the Record Value: You will see three fields: Type, Hostname, and Value. Copy the unique Value provided.
  3. Create a New TXT Record: Log in to your domain host's DNS management page and create a new record with:
    Type: TXT
    Host/Name: Your domain or @
    Value: Your verification code
  4. Verify: Save the record. DNS changes may take time to propagate. Return to LetzSecure and click Verify.

Method B: Email

This is a good alternative if you cannot easily modify DNS records.

  1. Select the Email Method: In the verification window, choose the Email method.
  2. Create the Email Address: The platform will show you a specific email address you need to create (e.g., [email protected]).
  3. Send the Verification Email: Once the address is active, return to LetzSecure and click Send verification email.
  4. Confirm Verification: Check the inbox and click the verification link in the email from LetzSecure.

Whitelisting LetzSecure

⚡ Whitelisting is the most important technical step for accurate campaign results. It tells your email servers and security tools to trust our simulation emails, preventing them from being blocked.

STEP 1 Get LetzSecure's Sending Information

You can find our current list of sending IP addresses and domains in your LetzSecure dashboard under Settings > Whitelisting.

STEP 2 Configure Your Email Environment

You must add our IP addresses to an "IP Allow List" or create a mail flow rule to bypass spam filtering.

For Microsoft 365 / Exchange:

Use Microsoft's Advanced Delivery Policy. In the Microsoft 365 Defender portal, go to Threat policies > Advanced Delivery and add our domains and IPs under the "Phishing Simulation" tab.

For Google Workspace:

In the Admin console, go to Gmail > Spam, Phishing and Malware. In the Email whitelist section, add our sending IP addresses. We also recommend configuring our servers as an Inbound gateway.

STEP 3 Whitelist in Third-Party Security Tools

If you use an additional email security gateway (e.g., Proofpoint, Mimecast), you must also whitelist our IP addresses in that system.

STEP 4 Run a Test Campaign

After setup, run a small test campaign with a few internal users to confirm emails are delivered correctly.

Importing employees

Once your domain is verified and whitelisting is complete, it's time to add your employees.

  1. 1 Navigate to the Employees section in your dashboard.
  2. 2 Click Add Employees.
  3. 3
    You have three options:
    Add Manually: Enter employee details one by one. This is useful for adding a single new hire.
    Import from CSV: Download our CSV template, populate it with your employee data (first name, last name, email), and upload the file. This is the fastest way to add your whole team.
    Copy & Paste: Paste a list of email addresses directly into the text field.
