McAfee Endpoint Security

McAfee Endpoint (ePO) Security offers various endpoint security solutions to managed devices.  This article provides best practices recommendations to ensure smooth interoperability of Netskope Client and McAfee Endpoint Security installed in a managed device.

Recommended Reading

We recommend that you read these articles to gain a better understanding of how Client works and its interoperability with 3rd party apps.


This best practices and configurations are based on the following product versions.

  • McAfee Endpoint Security: 10.7
  • Netskope Client: 111.0.0
  • Microsoft Windows 10

Interoperability Configuration Requirements

We recommend the following configuration requirement to ensure Netskope Client is able to steer traffic to Netskope cloud and also allow McAfee to process their traffic without any conflicts.

Configurations in McAfee ePO Console

Default policies in McAfee ePO does not introduce restrictions on Netskope Client traffic. However, when creating a new policy ensure that the ports 80 and 443 are enabled and allowed in the McAfee Security Firewall rules.


HTTP/HTTPS traffic (via 80 and 443) is enabled and allowed in default firewall policy

  1. Login to McAfee MVISION ePO.
  2. From the top menu bar, click Policy Catalog.
  3. From the Products list, select Endpoint Security Firewall.
  4. Client New Policy button.
  5. For the new policy
    1. Select Category.
    2. Select McAfee Default for Create a policy based on this existing policy option.
    3. Give a Name for the policy and Click OK to complete this step.
  6. In the list of Rules, click the Edit button of the policy that you created.
  7. Under Firewall Rules, expand Web/FTP. In the Remote Port column, ensure that ports 80, 443 are Enabled and Allowed for outbound HTTP/HTTPS traffic.


    If the ports are not allowed or enabled, click the Edit button open the Edit Rule page to  select the Allow option listed under Actions and select Enable rule under Status.

  8. Click Save. This process ensures that the Netskope Client can steer traffic from the managed device to Netskope cloud.

Interoperability Validation

Netskope Client Functions

Netskope Client is validated to work smoothly with McAfee ePO. To view the validation tests for Netskope Client, see Netskope Client Interoperability
