The pricing has increased for us, impacting our organization due to its operational expenditure (OPEX).

Featured Reviews

Charles Slaustas - PeerSpot reviewer
Information Technology Contractor at Insight global
Supports seamless authentication for users across multiple organizations and personal portals
The features I use in Cisco Duo include Duo Pushes to confirm my identity to the device, and eventually as MFA security was increased, I actually had to use exchange passcodes. Sometimes, I have to go into the site and get into Cisco Duo to retrieve the passcode, and many of them have been two-factor, where the sites send a passcode that I have to enter into Cisco Duo. It has been more of the latter. I have not seen issues with lagging or crashing on Cisco Duo's end; it was usually on the client end, often because someone set up a bad upgrade or there were connection issues with the Cisco Duo cloud through the administrative site.
Karthik Kashyap T H - PeerSpot reviewer
Lead Engineer at a retailer with 10,001+ employees
Eliminates certificate expiration outages and offers good customization and reporting capabilities
Even though it allows for email editing, until version 23.1, you had to log on to the server, and the console itself used to take a lot of time. That has changed from the last release onwards. When you're defining the flow, there are some areas that can probably cause confusion to the users. If you want to rename the default field, you cannot rename it, which caused a lot of confusion during the initial days until everyone got settled in. Allowing the renaming or updating of the default field is something Certificate Manager can improve on. Certificate Manager has both the on-prem and the cloud versions, but the on-prem version is far more mature than the cloud version, which lacks a lot of features that the on-prem version offers, at least when we did the POC and evaluated the product. The maturity of the cloud version needs improvement. Additionally, when considering the on-prem version, there is a minor glitch in the system. When an administrator makes changes, they have flexibility regarding the approval flow. When dealing with a certificate that requires approval from several different teams, there is a minor glitch in the system where the name of the approver does not appear. This is a bug that we are currently addressing. Additionally, there is room for improvement in key management. Changing the default account name is not a straightforward process; it can be quite tedious. This is an area where improvements could be made. If there is a particular workflow that we want to tweak, right now, we can achieve it only via a PowerShell script. It would be great if they could also support a small Python script or anything to expand their scripting or adaptable workflow code base. Even though we can call another script from a PowerShell script, if someone doesn't have knowledge of PowerShell, that would be challenging.
