Providing remote access services to different classes of
users, in different locations, on different devices is key
requirement for todays mobile workforce. Such a myriad of
requirement scenarios often expose many remote access
systems limitations as they struggle to keep pace with the
modern organisaiton.
UAG Delivers comprehensive, secure remote access to corporate resources for employees,
partners, and vendors on both managed and unmanaged PCs and mobile devices. Utilising
a combination of connectivity options, ranging from SSL VPN
& Intelligent reverse proxy to DirectAccess & IPv6, UAG provides centralised and easy
policy based
management of an organisation's complete anywhere access offering.
Winfrasoft UAG Appliances are available on hardware
from HP; also with VMware and
Hyper-V solutions.
Note: Note: Microsoft ceased to provide
UAG 2010 via Volume Licensing as of 1 July 2014, however
Winfrasoft will
continue to offer UAG appliances until at least 2020. In
addition, Winfrasoft will
continue to provide supportor new and
existing UAG appliances beyond 2020 -
providing longevity to the UAG product suite.
Integrating a deep understanding of the applications published, the state of health
of the devices being used to gain access, and the user's identity – UAG enforces
granular access controls and policies to deliver comprehensive remote access, ensure
security, and reduce management costs and complexity.
- Comprehensive Remote Access (SSL VPN). As a comprehensive SSL VPN, UAG provides
multiple levels of access and tunneling to deliver internal applications and network
resources to remote users.
- DirectAccess. UAG extends the benefits of DirectAccess across the infrastructure,
enhances scalability, and simplifies deployment and ongoing management.
- Remote Access to SharePoint and/or Exchange. Optimised for SharePoint and
Exchange, UAG delivers secure, anywhere access for your employees, partners and
customers. Leveraging a combination of granular application filtering capabilities,
deep endpoint health detection and wizard driven configuration, UAG provides for
a simple and highly secure means of publishing Exchange and SharePoint deployments.
DirectAccess is very resource intensive and performance statistics should not be
confused with typical UAG web portal usage scenario user volumes. When deciding
on hardware for DirectAccess it is important that your hardware supports Receive
Side Scaling Queues (RSS) as Microsoft estimates that approximately 30% greater
capacity is achievable on RSS enabled systems. All Winfrasoft Appliances support
RSS natively.
The following table shows the approximate maximum number of concurrent DirectAccess
users for each appliance model based on typical usage scenarios. These numbers are
not hard limits, each appliance can physically accept more connections at the expense
of overall performance.
