Bitcoin Security Services. We monitor exchanges and evaluate their performance and availability to help our customers choose what's right for them. Your digital currency is stored in multi signature addresses. They are released by the approval of our rule based co-signer that supports limits, whitelists and more. We make sure your wallet software is up-to-date, uncomporomised and have the optimal security configuration. We also monitor unauthorized accesses to your wallet's private files. Your digital currency will not leave your wallet unless you approve it using your smartphone, e-mail or SMS. We use external and internal information sources to provide insights about the identity and the reputation of the receiver. We scan the network for active attacks and potential threats for your digital currency. We also analyze your behaviour to prevent suspicious activity.
