NetIQ does not have a limit on the number of users. The tool is secure by nature. It can have more than one billion users. Event-based systems know what has to be changed. SQL-based systems can only change using time and date. Event-based systems provide immediate results, while SQL-based systems need time to sync. It is totally different from a security perspective. Event-based systems can update all the systems in seconds or minutes. Other systems do it within 24 hours. The basic event-based system is AI-driven. It has some kind of robotics and programming. Other tools need programming. I like systems that have prebuilt ideas of security. NetIQ has been in the market for a long period. It has all the systems and connectors. There is not much coding. We just need to configure the products. We need not do any programming. I haven't seen any other product that needs only configuration to do the job. Most products in the market are SQL-based. They need programming. Some service providers who sell other products to customers do not sell NetIQ because they can make more money by selling solutions that need more consultancy and programming. More hours lead to more money.
