It's Not Your Fault

The freshness of the technology and its recent growth makes it really hard for the community - businesses and developers to develop strong practices in security.
Most of the developers are not aware of how easily security breaches can be exploited in their apps, and they're not to be blamed.Indeed, there's poor documentation from about the best security practices and there's hardly public reports of previous security breaches.

But it is Your Responsability

This lack of awareness doesn't justify not acting on security.In fact, you are required by law to protect your customer's data, and you don't want to risk malicious intrusions on your app, as they generally have a strong impact on customers and investors' trust.


Not Just a Tool. Experts.
