The Security You Need for Your Wireless Network

Top of Mind
Data security seems to be on everyone’s mind these days. And it’s
no surprise, with reports of new security breaches showing up on a
regular basis.
This has left many companies scrambling to protect their data. But
not ESTeem. We’ve spent a lot of time and effort on wireless
network security, ensuring our customer’s data transmissions are as
secure as possible.
We’ve intentionally thought through every possible scenario and
even interviewed customers to discover their deepest concerns.

Layers of Security
All this attention to detail has led to a sophisticated system that offers
layers of security to ensure your network is protected, down to each
data transaction. Our wireless network security options include:
Access Control List
This does exactly what it sounds like – it’s a list that controls what
devices can access your network. The list uses filters to allow or
restrict devices on the network based on their MAC addresses – the
unique, 6 hexadecimal field address assigned to each Ethernet device
at the manufacturer. A MAC address can’t be changed, is traceable
and serves as a permanent fingerprint for the device.

More Layers
Disabling Broadcast Probes & Hiding SSID
Your network can’t be hacked if it can’t be found. Disabling broadcast
probes and hiding SSID (Service Set Identification) prevent bad
actors from discovering your network.
Protected Management Frames
Forged management frames spoofed from other devices can disrupt
a valid user session. Negotiated between the client and the access
point, Protected Management Frames (PMF) are a next-generation
strategy to prevent such spoofing.

Layers on Layers
Proprietary Bridge Communication
The ESTeem Horizon Series is compatible with international open
communication standards, but the peer communication between the units
is a proprietary communication link.
No other wireless hardware can access the ESTeem peer network when
bridging between Ethernet networks, which creates an effective security
barrier for our radios.
When used in conjunction with other security measures, the proprietary
link can restrict access to your wireless network even further.

Advanced Options
The layers of security available with our Horizon Series radios extend to
several strategies that can provide additional wireless network security.
These include:
• Disabling remote access
• Disabling port access
• Setting a new administration password for each radio

Proper Precautions
While our Horizon Series radios provide layers of security, there are other
actions you can take to protect your data transmissions, such as:
• Banning key reuse
• Regularly surveying the network for unauthorized access points behind
your firewall
• Implementing an additional level of authentication
The most important action is simply to implement the available security
measures. Research shows hackers attack systems with lax security.
Don’t give them that opportunity.

The ESTeem Advantage
For over 30 years, we’ve designed, engineered and manufactured industrial
wireless radios and modems - all in the US and all specifically focused on solving
our customers’ most difficult networking challenges, no matter what the frequency.
Through all those years, we’ve stuck to the philosophy that applications will not
bend to fit the hardware. The solution must fit the application, and we work with
our customers to ensure they get the right wireless solution to fit their needs.
To that end, all of our models come with full compatibility
baked in (195E/Horizon, 192/195 Narrowband), and we
write our software/OS specifically for the components used
for optimum efficiency and performance.
