Welcome, mifo! If the relative clause is intended to be restrictive, that is, this particular type of exposure profiling permits such customization and others don't, then the sentence is fine as is; however, that can be used instead and would cause less confusion, I'd say. If the clause is nonrestrictive, you must use which and a comma before it.

mifoI feel 'that' might work betterI don't. That construction has all the marks of being a non-restrictive clause, and you should add a comma. It sounds to me like you're giving the reader extra information about what exposure profiling does, not talking about a particular kind of exposure profiling that is different from other kinds of exposure profiling.
mifoI thought I was going insaneWell, hopefully we've reversed that trend.
