Mirko Vucinic was both hero and villain for Juventus, as he scored their opener in the 29th minute, then got himself sent off at the stroke of half-time, which allowed Bologna to snatch an equaliser ten minutes into the second half.
According to quotes from the club's official website, Buffon was impressed with his side's fighting spirit.
"We were very aggressive and focused on overcoming our rivals despite being one man down," the Italian lauded.
"Obviously, with a full team, we would have had much more chances to win, but in sports there are unexpected events.
"This should make us proud of ourselves, this should spur us in the future, helping us to be more aggressive."
Centre-back Andrea Barzagli added: "We put in a great performance and the three points were the only thing that was missing.
"I think that this evening we were also a bit unlucky and their goalkeeper pulled off some fantastic saves. We'll keep going in the same way, because we dominated both the first and second halves, despite being down to 10."
The draw has left Juventus at the top of the Serie A table, with Udinese and Genoa on seven points.
