I am now involved in a lot of dialogue where enterprises are being asked to implement 2-Factor authentication for existing applications. Given that many of these systems have been around for years, let alone decades – with legacy infrastructures like Siebel, SAP, PeopleSoft, Oracle, etc – the idea of just retrofitting a 2-Factor authentication system into these architectures, is downright daunting.
Let me introduce SecureAuth for F5 Big-IP authentication, to solve this dilemma.
Take you typical IT infrastructure, oversimplified, of course. (See image #1)
SecureAuth Solves Integration 2-Factor Authentication – at “The Edge”

Image #1: Typical IT infrastructure, serving up web and file servers to external users.
Now if we want to integrated multi-factor authentication, we usually insert the authentication in either (1) of (2) places:
- The VPN
- The Web Server directly.
The VPN has the advantage of being a single point of contact for the external users and can provide SSO and authorization capabilities to both web and non-web content. Thus SecureAuth sells a lot of 2-Factor authentication at this domain.
But the disadvantage has been the cost of VPN licenses – which are usually conducted on a concurrent basis. And thus, if an enterprise is looking at a B2B or B2C deployment of the content, then the cost has been prohibitive.
The current solutions for this – is to conduct the 2-factor authentication directly at the web tier. This has the advantage of not including additional licenses to conduct the 2nd factor authentication.
This is great but then their has been 2-disadvantages here:
1) Many security team members do not want authentication to occur at the web level
2) Many legacy web applications are extremely difficult to integrate into, to provide a seamless 2-Factor experience.
Now being a web-guy, I can blog about these above (2) points for pages – but I will stand by my assertion that both of those are both prevalent viewpoints – with legitimate, real-world empirical evidence to back both statements.
So what is the answer?
How does an enterprise meet the ever growing 2-Factor authentication requirements on very important and very expensively developed web applications?
Look at image #2 – for an enticing solution to the problem.

Image #2: SecureAuth can integrate with the F5 Big-IP Traffic Manager, “at the Edge” and apply a security-compliant authentication
The SecureAuth solution, with its unique design of a built-in web server, is capable of being redirected from the F5 Big-IP traffic manger, if the user does not have a valid BigIP session ticket. SecureAuth unique design allows SecureAuth to:
- Register the user w/ a 2-Factor Credential
- Validate the credential if necessary
SecureAuth uniquely is capable of conducting both the credential registration (X.509 v3 or other) and validating the 2nd factor as well. The 2nd Factor can be:
- X.509 v3 Certificates
- SMS Text Messages
- Telephony Messages
- E-Mail OTP
- PIN OTP
- KBA
- Help Desk
It’s an amazingly flexible and easy to integrate solution. And its solves the issues that enterprises are struggling with – 2-Factor authentication to their high value and high volume applications.
