- Enhances overall web application security posture
- Reduces potential liability from security breaches
Cons
- May introduce additional complexity in implementation and maintenance
- Certain protections like Referer header checks can be bypassed in some scenarios or with certain browser configurations
- Over-reliance on tokens without proper handling can lead to security gaps
- Limitations in older browsers affecting cookie attributes such as SameSite
