Understanding Firewall Testing Challenges

Corporate firewalls create several testing bottlenecks that traditional cloud-based testing platforms can't solve. Inbound traffic restrictions block external test runners from accessing your applications, while outbound filtering prevents internal systems from communicating with external testing services. Additionally, many organizations operate in air-gapped environments where internet connectivity is severely limited or completely restricted.
