Vildor started the final three seasons of his collegiate career.[3] He had 42 tackles, 4.5 tackles for a loss and also lead the team with 11 passes broken up and four interceptions and was named first-team All-Sun Belt Conference in his junior season.[4] Vildor was named first-team All-Sun Belt for a second straight season and a Pro Football FocusAll-American as a senior after recording 27 tackles, two interceptions and six passes broken up.[5][6]
Vildor was selected by the Chicago Bears with the 163rd pick in the fifth round of the 2020 NFL draft.[9] He signed a four-year rookie contract with the team on July 21.[10] Vildor mostly played on special teams during the 2020 season. In the Bears' Week 15 game against the Jacksonville Jaguars, Vildor made his first NFL start at corner back. In 2020, Vildor played in all 16 games while starting in 1 and had 17 combined tackles and 1 pass defended. In the Bears' Week 11 game against the Baltimore Ravens, Vildor got his first career sack on Ravens quarterback Tyler Huntley. Overall in 2021, Vildor played in 17 games starting in 12 of them with 46 combined tackles, a sack, and 4 passes defended.
Vildor entered the 2022 season as a starting cornerback alongside Jaylon Johnson and Kyler Gordon. In a Week 5 game against the Minnesota Vikings, he got his first career interception off of Kirk Cousins. He finished the season with 34 tackles, five passes defensed and one interception through 11 games and nine starts. On December 23, 2022, Vildor was placed on season–ending injured reserve with an ankle injury he had suffered in late November.[11]
On November 14, 2023, the Detroit Lions signed Vildor to their practice squad.[17] He was signed to the active roster on December 5.[18] In the final game of the Lions season, while nearly intercepting a long pass from San Francisco's Brock Purdy, the ball hit Kindle directly in the facemask of his helmet and deflected upward to be caught by Brandon Aiyuk, eventually leading to a touchdown and continuing an unlikely 49er comeback drive in the NFC Championship loss.[19]
On April 3, 2024, Vildor re-signed with the Lions.[20]
