I read the context and I got another conclusion about the meaning of this juridical phrase. I would translate it differently, as followed:
"Fast-Tracking" = "إعطاء الأولوية"

Because: In the context of the original English phrase, "fast-track" refers to giving priority or expediting the processing of internal reports when there is substantial evidence to support knowledge or suspicion of money laundering. It does not refer to following or tracing something or someone in this particular context.

Here is the translation of the complete phrase:
"تنص إجراءات الشركة على إمكانية إعطاء الأولوية للتقارير الداخلية في حالة توافر أدلة جوهرية تؤيد معرفت أو اشتباه بعمليات غسل الأموال."
