Cam Hargreaves struck in stoppage time as Aldershot snatched a point from a draw at Sutton.
Hargreaves slotted home after Sutton failed to clear a corner three minutes into time added on at the VBS Community Stadium.
His goal cancelled out a 23rd-minute strike from Ashley Nadesan, who had found the net after the visitors blocked a couple of shots but could not get the ball away.
Aldershot had already been pushing for an equaliser, with Jack Barham denied by a last-ditch touch from Jack Sims in the 56th minute.
The home goalkeeper then made a double save nine minutes from time, first denying James Henry and then bravely getting up to stop Jonny Stuttle's effort on the rebound.
