Today, we will explore the topic of secure web gateway vs zero trust security or SWG vs ZTS. So, keep on reading to know more.
SWG vs ZTS: Definition
To begin, an SWG refers to a device that is a combination of firewall, VPN, IDS/IPS, web gateway, and security gateway. On the other hand, a ZTS is a technique that aims to provide a secure environment for users. This is by not allowing them to access the resources or applications that are outside the trust boundary.
Then, a zero-trust network is one where every user or client must be authenticated by the network before they can access network resources. It implies that if a user needs to access a resource, then they need to be authenticated first. This authentication process is known as “zero-touch authentication.”
In this case, zero-touch authentication ensures that only authorized users can access the trusted resources. However, this authentication process is not suitable for most organizations. As it will require them to use a lot of time and money to build the infrastructure required and deploy it all over the network.
Therefore, SWG largely provides the same functionality as ZTS but on a smaller scale. An organization may choose to deploy an SWG instead of a ZTS. As SWG does not require any significant change from their current network environment to work. However, to use an SWG efficiently, an organization needs to have a good understanding of how it works. And also on how it can protect them from cyber-attacks.
SWG vs ZTS: Differences
SWG and ZTS differ in terms of functionality as well as deployment requirements. Some of the differences between them are listed below:
- SWG only allows clients who are authenticated by security devices to access resources. While ZTS allows users who are authenticated by some other means (e.g., user accounts) to access resources as well. However, this authentication process must be done before accessing any resource on the network.
- ZTS requires changes in the infrastructure of an organization’s IT environment. While SWG does not require any such changes. SWG can easily be integrated with an existing IT environment without causing any problems for its users.
- ZTS requires two-factor authentication (2FA) for users who want to access sensitive information and resources. While SWG does not require 2FA and uses only a one-time password (OTP) or password for authentication.
SWGs are becoming popular nowadays as they provide all the functionalities that are present in ZTS at lower costs. On the other hand, when it comes to costs, ZTS is the cheaper option as it only requires the deployment of security devices.
Final Words
In general, SWG is a smaller-scale version of ZTS. As it can be used to provide the same level of security that is present in ZTS. But with fewer infrastructure changes. Also, when you are using an SWG, you need to be careful with your device settings and configurations. This is because if your device settings are not set properly, then you may expose your network to cyber-attacks.
