At Data Security Technologies LLC, we are developing innovative technologies for securing big data stored in NoSQL systems. Our first product, SecureDL system, is being built on top of existing NoSQL systems (e.g., Hadoop, Hive, Pig, Spark etc.) to enforce wide range of security, privacy and governance policies. In addition, SecureDL makes it easier to comply with many different regulations. Please contact us if you want to learn more details.
