Simple offers a bank account that has all the tools you need to manage your money built right in. The funds in your Simple account are held by our partner bank, BBVA Compass, Member FDIC. Simple provides everything else, including the Simple Visa® Card, our powerful iOS and Android apps, a beautifully designed web interface, and customer support that really cares.

Simple understands the devotion and effort that security work requires. As such, we encourage (and reward) the responsible disclosure of any vulnerabilities to us.

For the initial prioritization/rating of findings, this program will adhere to the Bugcrowd Vulnerability Rating Taxonomy. However, it is important to note that in some cases a vulnerability priority will be modified due to its likelihood or impact. In any instance where an issue is downgraded, a full, detailed explanation will be provided to the researcher - along with the opportunity to appeal, and make a case for a higher priority.
Please see below for exclusions specific to this program.
