I've been looking for an obfuscator to protect the source code of my little software, I don't want people to crack it. I looked on the internet but the average price was something like +/- $400 and I don't have such money!
So I decided to, beside the above reviews, give NETGuard a try. I have been facing one little issue with my file but the post-sale service is decent and a support guy helped me to resolve the issue. Now my file is protected, I cannot use dnSpy decompiler on it anymore!
I bought the cheapest plan possible, $5, and it gave me 2 points to spend on obfuscation. I only spent those $5 to get my app protected, and avoided to waste $500 on competitors. Let's see how long will my product be safe, I'll edit that review if I can in the future to let you know.
