Enterprise Network Proxy Security Solution: IP Whitelisting and Dual Authentication Configuration

Core Pain Points of Enterprise Agent Security Solutions

Many enterprises will encounter two types of typical problems when using proxy IP: one is that unauthorized personnel access the internal system through illegal means, and the other is that there is a risk of theft of traditional account passwords. These two problems can lead to serious consequences such as business data leakage and malicious attacks on the system. Proxy IP as an important entrance to the enterprise network, its security directly determines the protection ability of the entire system.

The first line of defense: IP whitelist precision control

The essence of IP whitelisting is to create trusted access lists. By pre-registering the IP addresses that are allowed access, the system automatically blocks all requests that are not on the list. Taking ipipgo's static residential IP as an example, companies can enter the exclusive IPs of fixed office locations and remote employees into the whitelisting system.

There are three key points to keep in mind when configuring:

1. Select a proxy service that supports the CIDR format (e.g. 192.168.1.0/24)
2. Setting up a mechanism for automatic updating of the whitelist
3. Preservation of emergency access

The static residential IPs provided by ipipgo support batch import, and together with the API interface, automated whitelist management can be realized. When abnormal login is detected, the system will automatically freeze the relevant IP and trigger an alarm.

The second guarantee: dynamic IP double authentication system

For scenarios that require a higher level of security, it is recommended to overlay dynamic authentication on top of IP whitelisting. ipipgo's dynamic residential IPs change the endpoint IPs every time you connect, at which point you can use the"IP+Dynamic Password" Dual Authentication Mode::

The program is widely used in e-commerce platform user login, financial system operation and other scenarios. When multiple requests from the same IP are detected within a short period of time, ipipgo's intelligent wind control system will automatically turn on human verification.

Live Configuration Demo

Take Nginx server as an example to demonstrate the configuration process:

1. Whitelisting

location / {
    allow 45.76.12.34; Dedicated IP provided by ipipgo
    allow 103.21.84.0/24;
    deny all; }
}

2. Dynamic authentication integration

Get real-time IP library via ipipgo API, work with Authy to realize two-factor authentication. Force a dynamic passphrase when a user accesses from a new IP address.

Frequently Asked Questions

Q: How do I manage whitelisting in a multi-location office?
A: ipipgo supports filtering IPs by city/operator, and can batch import regional IP segments. For example, if you select the combination of "Shanghai + China Telecom", the system will automatically generate the corresponding IP pool.

Q: How do dynamic IPs avoid authentication fatigue?
A: It is recommended to set the device crediting period (e.g. 30 days) and turn on the "Remember this device" function on the trusted device. ipipgo's IP reputation system will intelligently recognize commonly used devices.

Recommendations for safety program selection

Adaptation options are selected based on business requirements:

- Internal management system: Static IP whitelisting + basic authentication
- External services platform: Dynamic IP pool + two-factor authentication
- High-risk operational scenarios: IP Whitelisting + Dynamic Password + Behavioral Auditing

As the world's leading proxy IP service provider, ipipgo provides residential IP resources covering more than 240 countries and regions, and supports the flexible combination of various security programs. Its unique IP reputation scoring system can effectively identify malicious IP addresses and build intelligent protection networks for enterprises.
