Lloris gifted the visitors a shock first-half lead at the Groupama Stadium on Saturday evening as he failed to keep out Julian Green's shot at his front post.
The 31-year-old also came under scrutiny at club level last season for a few mistakes leading directly to goals, but Deschamps has defended his number one ahead of his side's World Cup opener against Australia next Saturday.
"Everyone will have their own analysis of Hugo's season," he told reporters. "Yes, he made three errors with Tottenham that cost goals - but he played 60 games, he also earned points for Tottenham, as he made points for the team of France.
"Tonight, obviously he knows it, he can do better on the goal that we conceded, even if there is an error of Djibril Sidibe before. But I'm not here to question everything. He has a long, painful season, he's going to get on with it too."
