IAST Outbound-Only Connectivity: Secure Runtime Vulnerability Detection Without Inbound Access

The firewall was locked down. No inbound traffic, no exposed ports. Yet the application still needed full IAST coverage. This is where IAST outbound-only connectivity makes the difference.

IAST (Interactive Application Security Testing) is essential for finding vulnerabilities during runtime. But most traditional IAST tools require inbound network access, opening your system to risks or causing friction with network policies. Outbound-only IAST flips this model: the agent sends findings out, but nothing ever comes in.

With IAST outbound-only connectivity, the agent runs inside the application’s process and streams data to the analysis service over secure, outbound HTTPS. There’s no need to punch holes in the firewall or manage reverse proxies. This architecture works in production, staging, or even highly restricted environments.

Security teams gain faster deployment because approval processes are simpler. Operations teams see less configuration overhead. Software teams can keep their infrastructure isolated, reducing attack surface while getting continuous security feedback.

Key advantages of IAST outbound-only connectivity:

• Zero inbound connections required
• Works behind NAT, firewalls, and strict network controls
• Simple rollout across multiple environments
• Lower operational risk compared to inbound models
• Continuous, real-time vulnerability detection

Choosing outbound-only IAST also means better alignment with modern cloud security practices. You can deploy it in Kubernetes clusters, ephemeral test environments, or on legacy servers—without changing inbound rules or security posture.
