For small offices connecting to the internet, what is a common security method?

A centralized gateway device serves as a common security method for small offices connecting to the internet as it provides an integrated solution for managing network traffic and security. This device often incorporates features like firewall capabilities, traffic routing, and network monitoring, which are essential for protecting the office network from external threats.

Using a centralized gateway allows the small office to have a single point of control for their internet traffic, simplifying security management. It can help prevent unauthorized access and safeguard sensitive data, which is particularly crucial for smaller organizations that may not have comprehensive IT security resources. This approach not only enhances the overall security posture by consolidating functions in one device but also streamlines access and efficiency for users within the office.

In contrast, while firewall software and intrusion detection systems can be part of a broader security strategy, they may not provide the comprehensive network management benefits that a centralized gateway device offers. A VPN, on the other hand, is primarily focused on securing remote connections rather than protecting the local office network itself. Thus, the centralized gateway device stands out as a foundational element of internet security for small office environments.
