I don't think it's a problem to know what equipment the Spanish security services have.
The Spanish royal family has a lot of security, well-prepared people who protect them.
In comparison, even the costs of the intelligence- and security services used for royals, ministers, diplomats, etc. are not specified in the Dutch State Budget because already detailed finances would be "information for potential terrorists". Of course anyone will know that the Spanish royal family is excellently prepared but that the security has three off-road motorbikes (and not five, or nine, or twelve) is quite operational information for any potential idiot.
According to the Spanish press, specifically La Razon and Vanitatis, Princess Leonor in Wales is accompanied by 5 bodyguards.
