Fraud prevention

Brex can prevent fraud before it happens by ensuring that only authorized users can access accounts and make changes.

Account security

Secure browsing


Our website uses industry-standard encryption to ensure protected transmission of data (HTTPS): AES-256 bit or better for RDS and S3 data encryption for data at rest and TLS 1.2 or better for transit.

Idle lockouts

Brex forces automatic signouts after inactivity to prevent unsanctioned access or use of the user’s account.

Security policy

Brex enforces a strict content security policy and iFrame protection to mitigate the threat of attacks such as ClickJacking.


Secure ID and password

Brex enforces strong password requirements and supports mobile biometric authentication (Face ID/Touch ID).

Activity confirmation

Brex leverages both automated and manual review mechanisms to confirm account changes such as password resets.

Identity verification

Upon account creation, Brex customers are required to set up two-factor authentication so that even knowing a user's password is not enough to compromise their account.

Device verification

We require a one-time authorization for each browser on every device you use to sign in to Brex, which ensures that only your approved devices and IP addresses can access your Brex account.

Single Sign-On (SSO) integration

Brex Empower’s SSO feature enables a secure — yet seamless — login experience through Okta, OneLogin, Microsoft, Google Workplace, and more identity providers (IdPs).
