They have a RAM/SeaRAM analogue which is better than just gun CIWS, but like you said this pales in comparison to the Burke's air defense loadout, or other Western surface combatants for that matter.
If I had to guess it's a Soviet-like strategy to focus on offense to get as many surface attack missiles into the air before their own ships are inevitably sunk. This would also explain the nearly nonexistent compartmentalization of munitions/fuel and poor facilities for damage control.
