Neither. They are covalent.

Disulphide bonds are covalent bonds. They are a convalent bond between the sulphur atoms on two cystine residues, an S-S bond. (The original amino acid is called cysteine but when they are modified to form a disulphide bridge they are called cystines)

Disulphide bonds are non polar covalent.
As far as I can ascertain there is no ionic bonding and only minimal
hydrogen bonding associated with disulphide bonds.

These are bonds formed between the sulphur found in the systene residue of the r group of an amino acid. As they are formed between two non metals, two sulphurs they are covalent bonds.
