If the user authentication is assigned to the firewall rule, only clients either fully conforming to the policy
("healthy") or clients being in "probation" state are allowed to access the protected network.
Barracuda Networks allows access even for clients in "probation" since we do not want to block new
connections or even terminate existing connections only because the antivirus patterns are not up-to-date for a
few minutes. Remember that the client is in "probation" while it tries to execute the (auto)remediation actions. If
the remediation fails, then it will become "unhealthy".
