Case Study: American International Law Firm achieves secure, behind-the-firewall cloud file sharing and full data control with CTERA Networks

Global Law Firm Chooses CTERA for Secure, Cloud-Based File Sharing

A global U.S.-based law firm with more than 2,500 attorneys and offices worldwide sought to modernize file access and collaboration by moving to a cloud-based platform while maintaining absolute control over sensitive client data. Public SaaS offerings failed the firm’s requirement for a fully private deployment, so the challenge was to deliver anywhere, any-device access and modern collaboration without exposing data to third parties or compromising compliance.

The firm selected CTERA Drive Share deployed entirely behind its on‑premises firewall with AWS S3 in a private VPC and firm-managed encryption keys, providing encryption in transit and at rest. CTERA integrated with Active Directory/SSO, MobileIron, and Outlook, enabled desktop sync and secure external workspaces (preview-only, expirations, restricted sharing), and added DLP, auditing and granular access controls. The result was a smooth transition to cloud-backed file sharing that gave attorneys modern productivity tools while IT retained full privacy, reduced data leakage risk, and met strict compliance and auditing requirements.
