That's a question of deployment, not capability. They've been used widely in the Middle East against drones since the 2010s with considerable success.

Yes a 99% success rate versus like 600 incoming still means some of them will get through.

Which is the same reason no level of military power is going to keep the Strait of Hormuz open (or at least, no level beyond a truly absurd one and even then - see the Kerch bridge in Crimea).
