Gatekeeper - Identify and Prevent Anonymous Data breaches in Cloud Apps

We are rapidly moving towards a cloud-based world. A recent survey says that by the end of 2021of 2021, 62% of organizations will be running 100% of their IT applications in the cloud. This is a massive adoption of cloud services such as, Salesforce, Office 365, and Box by large enterprises. However, Cloud Adoption has also introduced a new set of risks to both internal and external users, cloud applications and data.

Gartner, which ranked Cloud Access Security Broker (CASB) as the top technology for information security, predicts CASB’s growth to higher than any other information security market, growth rate for CASB: 37.2% in 2021, 33.2% in 2022, 32.0% in 2023 and 30.5% in 2024.

Common Challenges that organizations face in their Cloud journey

  • Most organizations are unable to replicate their organization security policies when they move to the cloud, as on-prem and cloud infra/controls are not identical.

  • The organization doesn't have visibility of shadow IT applications or non-sanctioned applications by their internal security team. Cloud applications are used by organizations without knowledge of their IT team.

  • Unauthorized data access and data protection related issues.

  • Unable to track user activities in the cloud environment including user information such as device and location info.

Zensar's Cloud Access Security Broker (CASB) protection service called Gatekeeper helps organizations to resolve the complex issue by delivering greater visibility, governance, and protection for cloud applications as below:

  • Our Gatekeeper services are placed between the enterprise users and cloud apps, maintaining complete application visibility. It provides a consolidated view of an organization’s cloud service landscape, and details about the users who access data in cloud services from any device or location.

  • Organizations often have employees accessing multiple applications in different cloud environments. When cloud usage is outside the view of the IT team, enterprise data is no longer under the organization's governance. Zensar’s services help to identify shadow IT applications and the specific users accessing it.

  • Once we get complete visibility of cloud applications and their usage, then the IT team enforces granular level access control based on organization security policy. These data-centric security policies prevent unwanted activity based on data classification, data discovery, and user activity monitoring of access to sensitive data or privilege escalation.

  • CASBs prevent unwanted devices, users, and versions of applications from accessing cloud services by providing adaptive access controls such as user and entity behavior analytics (UEBA) and threat intelligence for identifying anomalous behavior, network sandboxing, and malware identification and remediation.

  • Zensar CASB services also enable companies to meet their compliance with a regulatory requirement such as HIPAA, ISO 27001, PCI DSS, and more. A CASB solution can determine the areas of highest risk in terms of compliance and provide direction to the security team so that they can focus on the resolution.

In this digital era, it is imperative that a secure cloud strategy like Zensar’s Gatekeeper is in place, establishing a holistic security framework that seamlessly covers both on-prem and the cloud. Zensar is always at the ready to suggest, deploy and strategically manage CASB solutions for its clients in our hybrid networks that enhance security posture & negate security-related incidents. Zensar is considered by our customers to be the foremost security experts in the field, establishing a reputation that is second to none.
