The F2 and Formula E champion sits bottom of the championship, level with Williams newcomer Logan Sargeant as the pair have failed to score a point after five rounds.
With commentators then latching onto Red Bull third driver and eight-time grand prix winner Daniel Ricciardo having a customary AlphaTauri seat fitting earlier this month, rumours regarding de Vries' future began to swirl.
Red Bull motorsport advisor Helmut Marko has reportedly set next month's Spanish GP as a cut-off for seeing a marked improvement from de Vries, but this came before the cancellation of the flood-hit Emilia Romagna GP.
Speaking ahead of the Monaco race this weekend, de Vries addressed the speculation over the safety of his place on the grid and conceded it was not a "shock" to hear the uncertainty.
He said: "Yes [I feel safe in my seat]. Also, it's not a shock to me. It's normal. It's this industry. It's always been like this in Red Bull and in Formula 1. I genuinely believe it's no different than earlier in the season.
"You've always got to perform, you've always got to deliver. It's been like that throughout my whole career.
"As a driver, you always fight for your survival, and you always need to deliver to continue your career forwards successfully. It's normal. It's how it's been always."
