City Defend
Intra-Cloud Scalability

Our novel solutions are scalable across cross-cloud and nested cloud infrastructures allowing dynamic databases.

City Defend
Reduced Network Latency

Our technology functions with minimum network traffic and hence reduces the network overhead.

City Defend
Lightweight

Our state-of-the-art Searchable Encryption schemes are based on trusted atomic primitives that are lightweight and can be used in resource constrained environments.

Problem

Users have no control of the data stored on the Cloud resulting in the fraud and misuse of the data. The conventional encryption creates problems for the Law Enforcement Agencies by restricting surveillance. The General Data Protection Regulation (GDPR) compliance is also a requirement highlighted by the EU.

Opportunity

The Global Cloud Market is showing a Compound Annual Growth Rate (CAGR) of 22.2%. However, 75% enterprises highlight security concerns related to the Cloud Storage. So in order to benefit from the Cloud, we have to enable people to fully trust the Cloud and the services it has to offer. Therefore, giving people control over their data.

Solution

An API and a Cloud Integrated Solution that provides Searchable Encryption-as-a-Service (SEaaS).
This technology allows Cloud Service Providers, Enterprises and their clients to encrypt and outsource the data onto the cloud while being able to search over them.
