1) The number of IoT devices is expected to grow dramatically from around 6 billion in 2015 to over 21 billion by 2020, with businesses accounting for 63% of spending on these devices. 2) As IoT devices proliferate, increased visibility into these devices through profiling, monitoring, and flexible enforcement is needed to secure networks from threats. Network Access Control (NAC) can provide this visibility and control to protect enterprises. 3) NAC provides essential context awareness and control capabilities to block, quarantine, or redirect compromised endpoints, and its integration abilities allow for improved network security orchestration across multiple environments including cloud and data centers.

Gartner, Inc. forecasts that more than 2 billion new IoT devices will
be deployed every year, with nearly 21 billion in use by the end of
2020. Businesses will account for nearly two-thirds (63%) of the
spend on these devices.

3. How will the enterprise manage these
devices and stay safe?
Increased visibility, profiling of devices and role-based
monitoring with flexible enforcement capabilities are required
to secure the new wave of devices.

NAC is the only approach that can deliver
the internal visibility and control necessary
to protect the enterprise in the age of IoT.

5. NAC is an essential platform to a
multilayered defense.
Block, quarantine, and redirect end users and endpoints when an
Indication of Compromise (IOC) is present—all with granular
context awareness based on multiple endpoint insight.

6. Why? Changes in the architecture of
business networks make NAC more
important than ever.
• Networks include multiple locations and the integration of cloud
environments and data centers.
• Networks need to facilitate mobile, purpose-built and other
transient devices (especially as IoT deployments escalate).

7. If visibility and security are sacrificed, you could
become the next breach headline.
• For instance, an enterprise could be easily breached with pilfered credentials
corresponding to a connected device, system or third-party service.
• In such a breach, lack of context awareness and insight into the interconnectivity of
new and non-traditional systems and services can mean easy money for hackers.

8. Network Access Control is one intelligent
way to address the challenges of evolving
enterprise networks.
NAC is the only solution to provide:
Endpoint visibility including
configuration assessment
Bi-directional integration
for improved efficiency
and automation
Added context and more
granular controls for better
access management
Network orchestration
through integration

9. To simplify this idea, the best way to prevent malicious actors from
entering sensitive parts of the network is to deny access in the first
place while maintaining a clear view of the network.

10. Through integration capabilities, the network orchestration cyber defense plat-
form changes network security from a passive posture into defensive action
based on accrued contextual knowledge.

11. Now, the market is ripe for NACs to claim their stake in the security landscape.

12. What Can We Expect?
• The revenue upsurge in NAC is here to stay. NAC is an integral
platform for unifying network access controls across wired,
wireless and VPN networks.
• Security products and applications are
being developed to fit NAC visibility
and orchestration capabilities.
