Network visibility refers to the level at which IT is aware of everything within and traveling through a network. This visibility is accomplished with specialized tools that monitor traffic, applications, performance, and other network resources. To be effective, a network visibility solution must be scalable and provide data collection, aggregation, distribution, and delivery.
And while it sounds pretty straightforward, recent research has determined that visibility is often where enterprises struggle the most: nearly half of those working in mobile security had no idea how many mobile security incidents took place in the last 12 months. When IT can be more proactive in monitoring the network, they can make better and more-informed decisions around the flow and protection of crucial data.
Don’t fall into the same situation.
Increasing Network Visibility Decreases Security Risks
Improving the visibility of an enterprise network can provide a significant boost to security. Arming IT with the ability to more closely monitor network traffic for malicious behavior and potential threats in real-time (or near real-time) allows threat defense actions to be applied quickly, reducing the impact of intrusions if (read: when) they occur.
For example, if an unauthorized device accesses a corporate network and IT has sufficient visibility, technicians can respond immediately and lock down the device to prevent any further data leakage. Or consider the possibility of malware that is hidden within encrypted network traffic—visibility into this type of threat allows it to be prevented.
If your company were to experience a data breach? How quickly would you be able to identify the leak? How difficult would it be to stop the leak? How much would it cost your organization in time and man hours?
One of the main cyber-risks is to think they don’t exist.

Most experts agree that 100% protection from cybercriminals is both impractical and impossible. And the best approach to network protection is reliable network visibility. Here are three things that you can do to increase visibility in your network.
1) Map Your Network and Address the Gaps
Your infrastructure has blind spots. Are you monitoring DNS and DHCP at the device level? Are you keeping an eye on application performance? The first step to greater visibility is understanding the network landscape.
2) Establish Criteria for Network Visibility
To ensure that your approach to visibility is scalable and sustainable into the future, make sure to outline exactly what metrics should be measured. The second step to greater visibility is determining how the impact will be quantified.
3) Implement an Operational intelligence Tool
There are many high-quality tools on the market today that allow organizations the ability to increase visibility. However, solutions like NetMotion’s Operational Intelligence for Enterprise Mobility take this insight one step further, providing full visibility into devices, networks, locations, data usage and applications data flows across any network (inside and outside the corporate firewall). If your network supports lots of mobile endpoints, this solution will change your entire approach to security.
The 24/7 Approach
A 24/7 approach to monitoring users within your network, using software, is the single most important security policy your enterprise can adopt, because if you can’t see it, you can’t secure it.
