Share Trading Beginner?

I am new to share market. I will soon be opening a demat and trading account with some service provider. I have 2 queries :

1. I have to choose a company with whom I will open my demat and trading a/c.What is the gurantee that the company/organization in which I will open an demat account will not run away and make my investment of years a zero. As far as I know it should be registered with sebi. But is this enough? What if a registered company will become bank corrupt or if the company will run away? what will happen to my investments? What precautions I can take. I dont want to take risk as i will be investing all my savings for years in it.
