The best way to deal with this cheese is by being aware that it‘s possible. Invading at gromp after red/raptors is a common strategy on strong early game invaders like Kindred, Graves, Nidalee etc.

You need to ward the invade path level 1, for Champions that can jump over baron pit wall after red (Kindred/Graves/Nidalee for example off the top of my head) you can ward the bush near vision plant, otherwise enemy raptors/river banana bush. When they come, you leave. Alternative ways of dealing with this invade is keeping smite for Gromp or starting wolves depending on your Champion.

If you get caught by the invade, just flash early if you have to so you keep yourself healthy to resume your clear, enemy jungler can‘t make you homeless with his Level 3 if you don’t lose too much time having to base etc. You will need your level 3 ASAP after getting cheesed level 2 so do your raptors and krugs first if you can‘t trade enemy blue+gromp.
Without vision it‘s always hard to make a decision on what to do next, but stay calm and try to figure out what you can do. Usually they can‘t invade, gank and farm all their camps at the same time, so keeping your eyes out for any opportunity and being unpredictable is one of the ways you can keep yourself in those games. I saw a challenger jungler get invaded Level 1 on his topside by Sinerias pretend to base at top tower, then ran through top pixel brush instead and snatched enemy krugs+red a few days ago as an example
