Security is not an option.
It is a must in an environment where hackers try to crack databases every minute. We hear news almost every day about data breaches, so in the case of an e-commerce store, it is essential to have a hack-proof system.
The whole system is constantly watched by experts (i.e., ethical hackers) searching for defects and eliminating vulnerability by uploading patches. But don’t worry, you don’t have to hunt down updates all the time. Magento always notifies you when an update is available so you will know about fresh developments right away.
