Find out what is Gateway DLP? Can it prevent sensitive data from leaving your organization?
What Is Gateway DLP?
Gateway DLP is a technology that is used by organizations to protect data. It resides at the gateway, which is the entry point of the organization and is located on the network perimeter. The technology inspects data that are leaving or entering the network and if it matches a predefined rule, it will block or allow the data to pass through.
Gateway DLP can be deployed as a purpose-built device. This is integrated into an existing network infrastructure appliance, or even running on a virtualized platform. Also, it can be deployed either at the demarcation point.
It is where your internal network meets your external connection point (e.g., ISP). Also, it is where an Internet connection comes into your organization (e.g., public cloud). Thus, these are commonly referred to as “perimeter” devices.
Gateway DLP Deployment
Gateway DLP can also be deployed at a point where sensitive data is leaving or entering your organization, called “endpoint” devices. This type of deployment is especially beneficial if you have sensitive endpoints that are hard to reach on your network perimeter. These are such as mobile devices and laptops with external hard drives attached.
Gateway DLP can be effectively used in conjunction with other technologies. These are such as encryption to help protect sensitive data when it leaves the organization via email or file sharing for example.
How Will You Protect Sensitive Data?
The growth in demand for cloud services has increased the need for effective data loss prevention solutions. It can secure information whether it is stored in a private or public cloud environment. Cloud-based data loss prevention (DLP) protects any storage device that can be connected to a computer (i.e., USB drives).
Cloud-based DLP allows you to keep track of the location of all external storage devices. This is to monitor their activity without having to physically access them. Also, this gives you additional control over sensitive information that leaves your organization through USB drives and other removable media devices.
It also allows you to control what information goes into any portable storage device that enters your organization’s premises. Also, this accesses its systems through gateways. These are such as cloud-based Web gateways, Web gateways, and proxy servers among others.
Data Loss Prevention Solutions
Gateway DLP solutions use well-defined rules, policies, and categories to help organizations gain visibility. This is into their corporate and personal information assets as well as control access to those assets. So, it is based on business needs and compliance requirements
The solutions can also be used to capture and analyze data moving through the gateway to detect policy violations and suspicious activity. Gateway DLP solutions can also be implemented in multi-gateway configurations. So, to manage information that is entering and leaving your organization from multiple entry points.
These are such as an Internet gateway, Web gateway, proxy server, and others. Gateway DLP uses the following categories of data loss prevention rules to identify sensitive information. Rules that are based on enterprise or industry policies that are created by IT professionals in large organizations.
