What is going to solve the challenge of securing remote access?

Adding one point solution after another for mobile access may have its advantages. But do the benefits outweigh the additional costs, complexity and confusion? Especially when you consider the need for all the supporting SSL VPNs.
The “Extra” power of remote access
Remote access to corporate IT systems gives enterprises something extra. Extra savings from lower real estate costs. Extra productivity because users can continue working wherever they happen to be. Even extra simplicity in the IT environment – if it is done in a strategic manner.
But with remote access becoming more important to enterprise success, IT teams need to find a consistent remote access model. They need to reduce point solutions, unify access policies so they follow the user and ensure that business resources remain fully secure.
When SSL VPN were the tool of choice
In the past, SLL VPNs were the tool of choice when it came to securing remote access. Why? Because they provided access to particular applications as well as full access to the network. This meant they could be a fast fix in supporting each new point solution added when users demanded improvements.
Adding all these point solutions to meet ad hoc mobile access requirements seems to have made sense on one level. It allowed IT teams to react quickly without impacting the core IT environment.
On another level, more and more point solutions created a high degree of IT fragmentation. Not just because of the individual solutions. But also because of the extra VPN technologies and specialised gateways needed to support each one.
With the subsequent rapid proliferation of mobile devices, the environment became even more complex. SSL VPNs were not enough. Device management at the edge was required. New application usage via SaaS came to the fore. Suddenly, enterprises were relying on too many remote access technologies.
The consequences were significant for IT teams:
- Multiple URLs made remote access less intuitive for users,
- Increased complexity took up valuable IT time,
- High total cost of ownership (TCO) placed a greater burden on the IT budget, and
- Vulnerabilities increased due to multiple access points.
Unifying the architecture
The bad news is that these issues persist as ways of working change and trends like BYOD have encouraged more and more mobile users. In particular, mobility has created its own security problem through the sheer proliferation of devices. IT teams have had to deal with multiple network access points, disparate operating systems and increasingly sophisticated mobile cyber attacks. In some cases, IT teams simply could not introduce access controls fast enough to keep up with the threats.
The good news is that it doesn’t have to remain this way.
With a unified secure remote access architecture, IT teams can now consolidate existing point solutions and continue to meet demand for remote access. Using Citrix NetScaler, they can do this without the complexity of added mobile VPNs or specialised gateways.
In simple terms, NetScaler gives users a single URL for accessing any application from any device.
- For IT teams, the impact is even bigger:
- Reduced TCO because of a single secure remote access solution,
- Better control over access management,
- Faster response times for fulfilling new requests, and
- The ability to deliver a better all-round mobile user experience.
And what are the end results for the enterprise with NetScaler? The ability to significantly reduce the associated costs, complexity and security risk of implementing remote access solutions. At the same time, increasing user satisfaction and productivity.
