Dfence detects and prevents unauthorized concurrent access to your SaaS platform. Secure your platform and convert account sharers into paying customers.

When users share accounts, you lose potential subscriptions. Every shared account represents a missed opportunity for revenue growth.
Real-Time Detection in Three Steps
Dfence integrates seamlessly into your application to detect concurrent access instantly.
Add our lightweight JavaScript SDK to your website. It automatically tracks device IDs and monitors user sessions.
When multiple devices access the same account simultaneously, Dfence detects it in real-time using Redis-backed session tracking.
Block unauthorized access or show upgrade prompts. Convert account sharers into paying customers.
Everything You Need to Protect Your Platform
Detect concurrent access instantly with sub-second latency. No delays, no false positives.
Set custom device limits per user tier. Enforce single-device or multi-device policies based on subscription level.
Minimal impact on your application. Our SDK is only ~15KB and runs efficiently in the background.
Automatically pauses monitoring when users switch tabs or minimize windows. Smart resource management.
Track all detection events. Integrate with ClickHouse or AWS Kinesis for analytics and reporting.
Simple JavaScript integration. No complex setup. Works with any framework or vanilla JavaScript.
