Your Guest Wi-Fi Could Be an Open Door to Your Business

A CRM so smart, it updates itself.

HubSpot's CRM is so smart, it now updates itself. Calls get logged and summarized the moment they end. New leads get researched and a first outreach drafted, automatically. Deals move forward on their own, with next steps flagged before you have to ask. 

Even the one repetitive task you've been meaning to fix can now run itself, no code required. Customers using it are already seeing the difference. 

This isn't the CRM you have to work hard to figure out. It's the one already working before you log in.

Guest Wi-Fi Isn't Automatically Secure

Offering wireless internet to visitors, contractors, and customers is convenient. But simply naming a network “Guest” doesn't guarantee that it's isolated from internal business systems.

Poor Network Segmentation Creates Hidden Risks

If guest devices can communicate with internal servers, printers, or employee computers, an infected visitor's laptop could potentially reach resources that should never be publicly accessible.

Shared Passwords Are Difficult to Control

Guest Wi-Fi passwords are often displayed at reception desks or shared with dozens of visitors. Once distributed, those credentials can remain in circulation long after the original guests have left.

Why are so many brands shifting ad spend to CTV?

For marketers who want a presence in streaming, Roku is the obvious place to go. With 47% of all streaming time in the US, it has more reach than every competitor. Discover how Roku Ads Manager can spread your message across 100+ premium apps in a single, self-serve ad buy.

Misconfigured Access Points Can Bypass Your Defenses

Wireless access points, routers, and network controllers need proper configuration and regular updates. An outdated device or incorrect firewall rule can undermine an otherwise well-designed network.

Device Isolation Matters

Client isolation can help prevent guest devices from communicating directly with one another. Combined with network segmentation and firewall restrictions, it reduces opportunities for lateral movement and unauthorized access.

Make Guest Access Truly Separate

Place guest Wi-Fi on a dedicated network or VLAN, block access to internal resources, update wireless infrastructure, enable appropriate client isolation, and review access policies regularly. Your visitors should be able to connect to the internet — not explore your company's network.
