The Cloudmersive Virus Scanning API provides convenience APIs for remote scanning of Cloud Storage via Cloudmersive basic and advanced scan for major cloud storage providers including AWS S3, Azure Blob Storage, Google Cloud Storage and Microsoft Office 365 SharePoint Online. These APIs accept cloud storage keys and return scanning results in one synchronous request/response API call. All handling of cloud storage keys is stateless; in other words it is processed in-memory during the transaction and this memory is freed after the transaction completes and the response is returned. Cloud storage keys are not stored by the API for security and privacy reasons.
