I like the ease of use and how well it integrates with other products. It's not as user friendly as some of the more expensive solutions, but it works very well. We've been able to automate many different aspects of our certificate lifecycle in one place, which has really helped streamline processes. The support team is also fantastic! They're always quick to respond to any questions or concerns we may have and are incredibly knowledgeable. This product is great for organizations who require automation of their certificate lifecycle. We have been using topki since 2013 for our e-signature product and it's very easy to use. The price of the solution was also one of the best in the market. The implementation process was very smooth with only one day of training.We were able to migrate our legacy applications to topki with little or no downtime. With the help of topki we got rid of paper documents which has been causing delays in the signing process.
