DuPont Kevlar and Aramid are technically the same thing and therefore offer the same level of protection, as DuPont is simply a brand name of aramid fibre technology. However, due to it being the first para-aramid developed, its name is synonymous with the term aramid. Kevlar is a registered brand name, used for products manufactured by the  DuPont  company, but it is still referring to aramid fibre. DuPont uses aramid fibres to produce body armour and bulletproof vests, but when it’s used elsewhere, you’ll see it referred to by its generic name, aramid fibre.
