On our arrival to West Palm Beach; we were cleared to descend to 2;000 ft. and to expect the visual approach to [Runway] 10L. I told the First Officer I'd like to begin the visual approach at ZISUR which is the final approach fix and glide slope intercept for the ILS 10L. The approach controller gave us vectors inside of ZISUR. We turned as instructed and a little while later he asked us did we see the airport. We said we did and were cleared for the visual approach. As we were at 2;000 ft and inside ZISUR we were above the glide path.  I descended as necessary to be on glide path. We were in total VFR conditions. At this time the controller said he had an altitude alert. We continued with our approach and we were fully configured and stable at 1;000 ft as per our SOP. We landed as normal.
Pilot reported receiving a Low Altitude Alert from ATC.
