You can enable the `permissive` mTLS mode to ensure existing non-mTLS service-to-service traffic is allowed during the onboarding phase. The `permissive` mTLS mode enables sidecar proxies to accept both mTLS and non-mTLS traffic to an application. Using this mode enables you to onboard without downtime and without being required to reconfigure or redeploy your application.
