Endpoint Detection and Response Advanced Threat Protection Platform


  • Need to enable secure communication between Advanced Threat Protection (ATP) or Endpoint Detection and Response (SEDR) and Active Directory (AD).
  • Where do I find the required AD certificate?
  • How do I update the certificate for AD in ATP or EDR?



Endpoint Detection and Response 4.0 or later

Advanced Threat Protection 3.0 or later


  • You are configuring Active Directory (AD) in EDR so that AD users can login and use the EDR web user interface.
  • You have configured AD in EDR and you need to renew a certificate that is expiring or has expired.


To export the AD certificate from the AD server and upload/update it in EDR:

  1. Log on to the AD server
  2. Click Start > Type MMC and press Enter to open MMC
  3. Click File > Add/Remove Snap-in, click to add certificates to selected snap-ins, select computer account, select local computer, click Finish, click OK.
  4. Expand Certificates > Personal > Certificates
  5. Right click the AD certificate > select All Tasks > click Export
  6. Upload that AD certificate to the AD connection in the SEDR web user interface
    1. On the left navigation pane, click
      Active Directory
    2. Click
      +Add Domain
    3. Check to ensure all fields are filled in correctly according to your environment's configuration
      • IMPORTANT: the NetBIOS name field is required as of SEDR 4.3
    4. Check the box to upload or attach the new or updated certificate.
