Wi-Fi’s Evolving Use Case

2010 – Traditional Wi-Fi

• Secondary network

• < 1 device per users

• Design for Laptops & coverage

• Designed for Access

• 2.4GHz centric

• Application focus – Web & Email

- I can Connect, so it works

2016 – Performance Wi-Fi

• Primary network

• 3+ devices per users (IoT)

• Design for handhelds & Performance

• Must design for Secure Access

• 5GHz and 2.4GHz - both required

• Application focus – Anything (real-time)

- If I can’t do what's needed, it’s broken!

Secure Access: Enterprise Campus HQ

Solution Overview

Distributing the FortiGate Controllers

throughout the network/campus

improves capacity scaling for high-

density, high performance and high

capacity, especially as you migrate to

802.11ac.

This design also distributes the WLAN

and security processing load across the

multiple resources.

AP traffic is tunneled to the nearest

controller, and optionally may be dual

homed to allow failover to a second

controller for resiliency.

20

Secure Access: Enterprise Edge Gateway

Solution Overview

Smaller environments can use a single

FortiGate for WLAN management as well

as to secure your network at the edge.

In this deployment model, each FortiAP

uses CAPWAP tunnels to connect to a)

FortiGate for policy processing and

forwarding.

The FortiGate Firewall function provides

protection from network threats, whether

they originate from the Internet or from

wireless device

21

Secure Access: Distributed Enterprise

Solution Overview

The Distributed Enterprise will vary

significantly in size and scope, so the

FortiNet Secure Access solution offers

multiple deployment options, several

identified here.

Using a FortiGate, acting as a wireless

controller and security gateway and

connecting to the remote sites.

Some sites may consist of just FortiAPs,

tunneled back to the HQ for WLAN

policy enforcement and security.

To reduce the traffic load heading to your

HQ or data center, onsite FortiGate can

be deployed and configured to handle

policy enforcement and security locally.

22

Secure Access: SOHO with Centralized Control

Solution Overview

Another deployment model is the

centralization of one or more FortiGates

in your data center to support the

aggregation of many APs deployed in

remote locations that do not have

a local FortiGate.

In this model the remote FortiAPs

connect back to the FortiGate cluster via

a CAPWAP tunnel over the internet and

appear to the controller like any other

connected AP.

23

Secure Access: Small Branch

Solution Overview

Small branches, retail or SMB models

are also supported and in these

deployments it is typically not necessary

to deploy a FortiGate onsite.

One or more FortiAPs can be installed

independently. Each AP discovers its

remote controller and sets up a

CAPWAP tunnel to it. The traffic passes

over the tunnel and terminates on the

FortiGate for security processing and

forwarding.

However the use of split tunneling or

bridge mode allows traffic destined for

the local LAN hairpin the traffic through

the remote FortiGate

24

Secure Access: Campus/Enterprise

Solution Overview

When customers prefer to separate the

management of network access layer

from network security, Fortinet address

this with our FortiWLC controller solution.

In this case you would also distribute the

WLAN controllers at the access layer,

providing support for the highest density.

This model improves capacity scaling,

especially as you migrate to 802.11ac,

and spreads the WLAN processing load.

AP traffic is tunneled to the nearest

controller.

The addition of a FortiGate, with SSID

traffic mapped through it will complete

the Secure Access Solution

25

Secure Access: Enterprise Edge Gateway

Solution Overview

Smaller environments can be managed

by a single controller and all APs traffic

will be tunneled back for policy

processing and forwarding.

For security, SSIDs are mapped to

different VLANs in the standalone

FortiGate, then subjected to your defined

security inspection policies.

Once again the FortiGate will provide

protection from the wireless edge as well

as Internet.

26

Secure Access: Large Branch

Solution Overview

Large branches require just as robust a

WLAN solution as the Enterprise. In this

model you can use a FortiWLC , with an

FortiGate to provide complete threat

protection at all sites.

SSIDs are mapped locally to VLANs on

the FortiGate to provide security for all

traffic, regardless of its destination.

Distributing processing at the branches

improves performance, reduces the

volume of traffic forwarded to HQ by

keeping local traffic local.

27

Secure Access: Small Branch

Solution Overview

In small branch office or home office

deployments, an on-site FortiWLC may

be cost-prohibitive. Yet you still want to

secure Internet traffic.

In this case, APs can be installed without

a local controller, allowing non-local

traffic to be tunneled back to your HQ,

where the controllers reside.

Traffic should then be forwarded to your

centralized FortiGate for security

processing before it is forwarded to the

Internet, and vice versa.

28

Secure Access: Cloud Managed

Solution Overview

FortiCloud provides provisioning,

configuration and analytics, designed to

enable simple and rapid deployment of a

fully managed wireless network.

Via a single dashboard for managing the

WLAN and security for the entire

network, it offers unlimited network

scalability with all the benefits of

centralized management, and avoids the

cost of controller and management gear.

The FortiAP-S series APs include

FortiCloud registration functionality in

their firmware, which enables zero-touch

provisioning. When installed, the APs will

discover and connect to FortiCloud and

provision themselves, automatically.
