We need to resolve the copyright and trademark issues concerning our customers. In our busy digital design studio, JScrambler offered us with an easy-to-use toolkit that met our requirements. We had a very complicated javascript-based SPA and we don't want others to see our business processes, so jscrambler was the right solution to cover it and make it more difficult for others to see the logic behind it.

Implementation is quite easy and it is the whole package

We used to get a lot of phishing attacks and MitB attacks on the websites created in our company. Sometimes it caused us money as well because we have HDFC, IDFC banks as our client too. we started using jscrambler and we were able to stop these attacks
