  1. Tuesday afternoon, several of our end-users are reporting issues with Outlook attachment handling when ESET Endpoint Security v 10.0.2045.0 is installed. Outlook locks up when attempting to save, preview or view attachments. We have tested PDF & XLSX attachments, both file types have the same issue.

    We have tried many things, the only certain resolution is uninstalling ESET Endpoint Security.

    The affected computers are running these versions of office.
    Microsoft 365 / Outlook v2301 16.0.16026.20238
    Microsoft 365 / Outlook v2303 16.0.16227.20280
    Microsoft 365 Apps for business / Outlook v2304 16.0.16327.20214

    Some users are on W10 others are on W11

    What settings can we change to make this a better situation for our end-users.

  2. We use EES v9.0.2032.6 to protect our Windows systems. On-premise Protect v9.0.1144.0 manages our policies. We block executable file downloads using URL Address Management:
    Edit Policy | Settings | Web and Email | Web access Protection | URL Address Management | Address list | Edit | Add to List of blocked addresses: *?.exe

    From time to time, we add addresses to the allow list, for example: *.lscsoft.com/*

    Today, an accountant needed access to Glance a remote desktop application. I don't want all users to have this added to their allow list. So I setup a new policy and applied it to my computer for testing.
    Edit Policy | Settings | Web and Email | Web access Protection | URL Address Management | Address list | Edit | Add to List of allowed addresses: *.glancecdn.net/screenshare/*

    No joy, I am still blocked. If I add glance to the main policy everything works.

    How do I have multiple allow lists? One for the general population, then others for those with special needs?

  3. When we go to banking sites, our fleet of computers are supposed to be redirected to ESET Secure Browser. This will work for a month or so, then quit working. The last time it quit working, support corrected the problem by toggling the policy settings off, waiting a bit, then toggling back on. Previously, the problem affected all browsers, now it seems to only be Chrome.  Anyone have a reliable method of making this behavior reliable?

    Product versions: 

    • ESET Management Agent 9.0.1141.0
    • ESET Endpoint Security    9.0.2032.2
    • Detection Engine    24433 (20211210)

    We are using these policy settings in Protect:

  4. Support helped me with this. We added "s3.amazonaws.com" to the list of known certificates to be ignored via Advanced Setup | Web and Email | SSL/TLS | List of Known Certificates

    We then exported my local workstation's configuration, imported it as a policy in Protect and applied the policy to our client workstations.

  5. On workstations with Endpoint Protection, I am getting: ERR_BAD_SSL_CLIENT_AUTH_CERT
    when trying to access these urls:
    https://white_label.s3.us-east-1.amazonaws.com/UFW/logo-ufw-white.png
    https://white_label.s3.us-east-1.amazonaws.com/UFW/Favicon-UFW-blue.png?v=2

    Without endpoint protection, Chrome tells me the corticates are fine. Any idea what's going on and how to clear the issue?

  6. Thank Marcos, what is the best way to make the email notification a successful feature request?

    Our block list looks like this:

    # {"product":"endpoint","version":"8.1.0","path":"plugins.01000200.settings.stProtocolFiltering.stUrlLists.2.strAddresses"}
    *?.exe
    *.*.exe
    *.docm
    *.xlsm
    *.pptm
    *.vbs
    *.bat
    *.wsf
    *.rar
    *.winzip.com

  7. I want an email when a client attempts to download an executable. We are using URL Address Management in Web & Email via /era/webconsole/#id=POLICIES to block executable downloads. I have tried configuring notifications via /era/webconsole/#id=NOTIFICATIONS, but haven't stumbled on the correct solution.

    We block the download, the client sees:

    Website blocked
      The web page is on the list of blocked websites specified by the user.
      Access to it has been blocked.

     

    Please help

  8. I like the proxy idea, in particular, if we are able to use CloudFlare to proxy the traffic, we would pick up quite a few benefits. For example CloudFlare will block known bad actors, significantly reduce the likelihood of DoS attacks and allow us to easily restrict access to known networks based on ASN &/or geography. The ASN issue is quite helpful, we see some adversaries come in via local Internet providers, however the vast majority attack from overseas or via data centers such as Azure, DIgital Ocean etc.

    Is there a step by step recipe for this use case?

  9. We self-host ESET Security Management Center, forwarding only port 2222 to the ESMC box, all other activities are restricted to the local LAN.

    Anyone care to describe how safe we are from the evil-doers of the world? We are considering putting ESMC on a VPN, but would like some assurance that this isn't necessary.

    Looking at /era/webconsole/#id=DETECTIONS, it is clear evil-doers are trying to penetrate our beloved security system.

     

  10. I never know if the ESET Secure Browser (ESB) will be spawned. For example this morning it was spawned when I went to pnc.com, but not citi.com. Other times citi.com will trigger ESB, but not usbank.com. Still other times usbank.com, but not chase.com.

    How can we make sure ESB is triggered 100% of the time? It doesn't inspire confidence in the ESET stack.


    ESET Endpoint Security 8.1.2031.0 managed via ESET Management Agent 7.2.1266.0, Chrome Version 91.0.4472.164 (Official Build) (64-bit), Microsoft Windows [Version 10.0.19043.1110]
