A typical 1 oz serving of fontina cheese contains 7.2 grams of protein (25.6 g per 100 g), which makes it a good source of protein. That covers roughly 14% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 26% of the calories in fontina cheese come from protein, so it is moderately protein-dense. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
Among the 81 dairy foods in the database, fontina cheese ranks 36th by protein per serving, and 374th out of all 796 foods on the site. Set against milk (whole), another dairy food entry in the database, a serving carries about 0.5 g less protein (milk (whole) has 7.7 g per 1 cup).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving above is measured by weight at 28 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
