Damien Trut

CTO, XLSTAT(external link)

After having spent a lot of time evaluating other solutions, we felt we had to try out Cryptlex! The solution was very easy to integrate into our system and the support team were very prompt and efficient any time we needed assistance. We have now reduced technical difficulties to a very low level and we are focusing on the continual improvement of our business model via the Cryptlex platform. We can now provide our customers with a flexible and customized user experience, giving them the freedom to choose the best product to meet their needs. All of our business and product requirements have been met with this solution and with the implementation we've deployed using Cryptlex.

Steve West

Infrastructure Manager, More4apps

This is the only LaaS product we found that could satisfy our requirements for silent licensing and floating-concurrent seats. Provided a very flexible floating-concurrent model for integration with our C# application. The Rest API is very easy to use, so that end users have "silent licensing", they are unaware of the Cryptlex service operating in the background.

Mitch Barnett

Owner, Accurate Sound

Easy to integrate into my product, operations is seamless and reliable, tech support is top-notch. I looked at over a dozen product/solutions over several months and had all but given up on finding a licensing solution that would meet my requirements. Cryptlex was recommended to me by another company in my industry indicating that have had a good experience using the product, saying it was flexible and rock solid. Cryptlex was able to answer in a timely manner with the right solution. The product works as advertised, easy to implement, easy to manage, rock-solid service, and tech support, all for a reasonable price. After using it, I am glad I chose Cryptlex.
