Protect your company, employees, and customers with simpler and stronger authentication. Deploy 2FA in minutes, not weeks. 2FA (and other user access security policies) built into the fabric of the infrastructure, not rigidly fixed to the applications. Enabling the use of any 2FA methods available on the market now and in the future without changing the core. Protection is available across the entire organization, spanning from on-premise, public and private cloud. Secfense is deployed in between your users and the applications they access. It learns the traffic patterns related to authentication. It can then enforce multi-factor authentication login and other sensitive actions without interfering with the applications existing code or database. Up-to-date 2FA methods are always available on the platform. Application changes don’t affect Secfense and applied methods. Take control over session expiration rules across all apps. Don’t rely on VPNs, base trust on users and their devices.
