There is no doubt that the safety and security of sensitive information is the primary concern in software application security. Data in transit, and in particular, data _at rest_, needs to be protected and to do so you need to put security controls in place. Security needs to be part of the full lifecycle of your software - design, development, testing & maintenance.
If you think you can’t afford to address application security now, think again - It’ll cost you much more in the future… Uber paid hackers a ransom of $100,000 to destroy the data they stole and then was fined nearly $500,000 for letting them steal the data in the first place http://ow.ly/J3WT50jPJtR. $600,000 may mean nothing to a company like Uber but what does it mean to you? Application security isn’t a luxury, its a requirement. Stop putting it off and get your data secured before its too late.
