NLE's Secure De-duplicated Multi-Cloud Storage is the future of primary storage. This solution combines the use of multiple public cloud storage services with fast local access to cached data, data deduplication, and enhanced security and reliability at very low costs. By doing so, this solution is ideal for enterprise customers as well as governments and large telco-operators. Namely, our solution focuses on security and storage-efficiency, ensuring that the data is always available, is repaired in case of any partial data loss, and is protected from the strongest of adversaries, without hampering performance nor usability. As a result, our solution allows us to extend the range of current datacenter services and features, without incurring high infrastructure costs and at competitive margins.
