Multisig wallets require multiple signatures (multiple wallets approving the transaction) to sign or confirm transactions and can be secured with either a hot or cold storage wallet. This method provides for much greater security as there is no one single point of failure. A multisig wallet secured via cold storage is the gold standard for security with crypto assets, but this protection comes at the expense of convenience. This type of storage should be employed for large asset balances that are kept for longer time frames.
