Visser, who joined the Valiants on a free transfer in August, made his full debut for the League Two side on Tuesday evening during their 0-0 (4-3) penalty shootout victory over Tranmere in the EFL Trophy.
The 31-year-old was his side's star performer on the night, pulling off an excellent save in the 85th minute to deny Kieron Morris, keeping the scores level and forcing the tie into a penalty shootout.
There, he was on hand to deny Tranmere's Otis Khan, Stefan Payne and Daniel Walker-Rice's respective spot-kicks to help Port Vale claim victory and get their 2020/21 EFL Trophy campaign off to the perfect start.
The fourth division side has been drawn in Group D in the competition, which includes League One outfit Wigan Athletic and the U21 side of reigning Premier League champions Liverpool.
Visser's heroics come just under a year after he achieved a similar feat for former club Exeter City in the same competition against Oxford United, when he saved all three of the opponents' penalties on that occasion.
The Polokwane-born shot-stopper was signed last month to serve as back-up to first-choice goalkeeper Scott Brown, but his performance on Tuesday will possibly have given manager John Askey food for thought about his selection moving forward.
