SecurAccess Overview Video

Authenticate On Any Device, Anywhere

End user experience is key. SecurAccess' patented methods resolve these issues by utilising:

  • Passcodes that can be sent by secure email
  • Soft Token apps for every device
  • Voice Call with passcodes entered in the phone’s keypad to session lock the voice network with the Internet
  • Real Time SMS Passcodes sent on-demand and session locked
  • Pre-loaded one time passcodes
  • Three pre-loaded one time passcodes within each message
  • Reusable passcodes that change each day or multiple days
  • All methods available for online or off-line authentication

Award Winning End User Experience

SC Magazine stated “The jury was particularly impressed by the solution’s ease of use and the range of channels available for distributing the numeric passcode” and gave SecurAccess the industry “Best Buy” category.

Good security shouldn't add complexity, SecurAccess is designed to keep authentication as easy as possible by:

  • Reusing the existing Microsoft (or other directory) password instead of a PIN
  • Dynamically updating the previous SMS message; no need to delete old text messages (pre_loaded and day codes)
  • Optional flashing of the message directly to the main screen (real time codes)

Self Help Desk

A self help web interface is included to allow users to request a temporary passcode should they lose their phones


Benefits to Users:

  • End user doesn't need to remember an additional secret piece of information as they can reuse the Microsoft or LDAP password.
  • End users only needs to enter one thing they know rather than two pieces of information as many other 2 factor authentication systems require a separate PIN.
  • All a user needs to do is read an industry standard 6 digit passcode from their phone. The user does not need to perform any mathematical manipulation to derive their passcode.
  • End user does not need to carry additional authentication devices.
  • Dynamically updating the previous SMS message removes the need to delete old text messages
  • Soft Token application available to all smart phones and desktop/laptop environments

Benefits to the business:

  • Any mobile phone that can receive an SMS message is supported without any SMS delivery delay issues affecting performance. This approach expands the range of users to include not only internal staff but also third-parties and even consumers.
  • No token deployment or replacement costs.
  • No token resynchronisation or PIN resets reduces the cost of helpdesk administration
  • Deployment to thousands of users in minutes via SecurEnvoy's deployment wizard cuts down the cost of deploying and supporting two factor authentications.
  • The personal security paid to a users mobile phone far exceeds that paid to a hardware token they are forced to carry. End users are more likely to notice their mobile phone has been stolen and more importantly are far more likely to report it missing. Therefore providing enhanced security to the business over token based solutions.

 Enterprise Class Solution

Full multi-domain support with redundancy and fault tolerance built-in.

"particulary well suited to businesses with a large remote workforce"



SecurEnvoy harness the power and scalability of Active Directory or other LDAP based servers as its core database. All replication is performed by the operating system siftware (domain controllers).

SecurEnvoy's radius server can scale to over 50 authentications per second. It utilises Microsoft's next generation .net framework and LDAP services.

As the next required user's passcode is not needed until the next authentication, any buffered delay at peak loads in sending the next SMS passcode message will not affect authentication performance.

The only limitation imposed on scaling the system is the number of users that Active Directory (or other LDAP servers) can manage in any single domain.

 Fault Tolerant

Each site is designed with two authentication servers such that if one of these servers failed or its delivery SMS gateway was unable to send SMS messages then this server will drop the incoming authenticate request. This action will cause the VPN radius client or IIS Agent to fail over to the next configured SecurEnvoy server. Note that as this solution is priced per user, additional servers can be added if required at no additional cost.

All user authentication data is stored and replicated in real time by Active Directory with each SecurEnvoy server being configured for up to two Microsoft domain controllers such that if an existing domain controller fails then SecurEnvoy ‘s server will fail over to the next configured domain controller.

SecurEnvoy is supported on clustered servers if required.

Failover between sites is supported out the box with no additional development required as follows:

If a user from one site authenticates at a second site and is in the same domain then Active Directory (or other LDAP server) synchronisation will ensure that the required authentication information is available at both sites and thus will be available to SecurEnvoy's authentication server.

Multiple SMS Gateways can be configured with fail-over.

Each SMS Gateway is continually checked for correct operation. If one fails for example the power is removed from a connected SMS modem, then this gateway is poled every 60 seconds with reset and initialisation commands.

 Multi Domain Support

Each SecurEnvoy security server can be configured with two domain controllers for each domain your company uses with no limit on the number of domains. The domain component of the userID is then used to dynamically switch the security server to the relevant domain. If no domain component is given in the userID then a default domain is used. Default domains are set at each radius client configuration such that each connecting VPN server can be configured with a separate default domain.


The only on going administration tasks required are the following:

  • Re-enable lockout account that have failed too many authentications since the last good one
  • Update users mobile numbers (can be self managed via help desk if required)
  • Enable temporary emergency access if a mobile phone is lost (can also be self managed via help desk)

SecurEnvoy supports role based administration with these roles:

  • Full Admin: Access to all admin GUI functions including server configuration,log, radius and user setting.
  • Help Desk: Can only access user setting and log information
  • Help Desk Groups: Can only administer users that are a member of an Active Directory (or other LDAP) group or sub nested group.
  • Config: System configuration settings only, no access to user authentication

Administration overhead functions are kept to in minimum as end user information is already available in Active Directory, no token management or resynchronisation is required and no PIN management is required.

In addition, temporary emergency access codes automatically switch back to one time codes after the administrator defined number of days. As user information is stored in AD then any users deleted from Active Directory will be deleted from SecurEnvoy.

Centralised management is support in the following way. Each security server can manage any user in any domain with remote administration being accessed via a browser (IE6, IE7, IE8 or Firefox).
