Security Features

LyncShield offers the following features:

  • Active Directory credentials protection – defining dedicated credentials that are different from the Active Directory credentials to minimize damage and risk in case of a stolen or lost device, or if the credentials are hacked.
  • Two factor authentication – By matching the device and user, the organization can limit users to using only corporate devices or specific devices that meet the company’s security requirements.
  • Blocks DDoS & brute force attacks and prevents account lockouts  – prevents account to be locked due to DoS, DDoS and brute force attacks or network password change.
  • Reverse proxy Lync publishing – scalable, event-driven and secure reverse proxy alternative for Microsoft Forefront Threat Management Gateway (TMG) to publish Lync.
  • Account lockout protection – preventing account lockout for organizations that wish to safely connect computers from outside the corporate network to their Lync edge access control server.


LyncShield is a server side solution that does not require any additional installation on mobile client.

The product is available on Microsoft TMG or on Bastion – a dedicated reverse proxy included as part of the solution.

The product can be implemented in an existing environment using already other network proxies such as F5 or Netscaler.
