Best Access Gateways
Access Gateway adds authentication and access control for on-premises applications without native federation support. It acts as a reverse proxy to enable SSO and centralized user authentication.
Key features:
- Allows secure external access to on-prem apps without a VPN
- Sits behind the firewall to monitor and authorize requests
- Integrates with legacy apps via HTTP headers and Kerberos
- Enables SSO for non-federated on-premises applications
- Adds headers and tokens to requests before passing to backends
- Provides authentication layer without modifying apps
In summary, Access Gateway brings user management and SSO capabilities to legacy on-premises applications. It enables secure external access without a VPN while keeping apps behind the firewall.

FAQs of Access Gateways
An access gateway is a device or software that provides secure access to a private network from the public internet. It serves as the entry point to the internal network and allows remote users to access resources inside the network.
Common types include VPN gateways which use virtual private networking, firewalls with access control, reverse proxies, SBCs (session border controllers) for VoIP, and API gateways for web APIs.
Access gateways enforce security through authentication, authorization, encryption, inspection of traffic, network segmentation, and advanced threat protection. This allows secure remote access without exposing the entire network.
Key functions include VPN, firewall, intrusion prevention, web filtering, load balancing, DDoS protection, network address translation (NAT), and more depending on the type.
Considerations include number of users/traffic volume, protocols required, security needs, high availability, scalability, network topology, management, and budget constraints. The gateway should align with your use case.
