Traffic interruption by ASM policy exchange?

With regard to transparent policies, there can be an impact on traffic if you are using threat mitigations which mask characters (Data Guard), or inject JavaScript into an HTTP response including brute force protection, bot defense, web scraping, persistent device tracking, and L7 DoS protection. There will be activity associated with these defenses even if the policy is transparent mode--remember that a DoS profile for example, works with or without an ASM policy.
