Secure Cloud Gateway


The term “cloud security gateway” refers to a new product category that combines multiple important security services into a single platform.

While the specific services included vary by vendor, all cloud security gateways work as a firewall for all enterprise traffic, sitting between users and the internet, cloud apps, and company resources. The finest cloud security gateways are as follows:

Provide secure, frictionless access to everything employees need, regardless of their location.

Give security teams complete authority over traffic monitoring, policy enforcement, and threat response anywhere in their environment.

In this piece, we’ll go through the full spectrum of functions that cloud security gateways should provide, as well as review three of the most popular options on the market today.

Why Are Cloud Security Gateways Increasing in Popularity?

Cloud security gateways, according to Gartner, are “points of enforcement for enterprise security policies that are positioned between cloud service customers and cloud service providers to insert business security policies as cloud-based services are accessed.”

These can be installed on-premises or in the cloud and will gradually phase out the company data center as the primary authentication, authorization, and encryption mechanism.

According to Gartner, the shift from datacenter to cloud security gateways is occurring because current trends have turned the enterprise network “inside out.” Massive adoption of SaaS, IaaS, and other cloud-based services has “inverted historical tendencies,” resulting in a new normal defined by the following:

  • More user work is performed off the company network than on it.
  • There are more workloads running on IaaS than in enterprise data centers.
  • More apps are consumed via SaaS than are consumed on-premises.
  • More sensitive data is stored in cloud services than in business data centers.
  • User traffic directed toward public cloud services is more than that directed toward enterprise data centers.
  • Branch offices send more traffic to public clouds than to business data centers.
  • Whether you believe the enterprise data center will be phased out over the next few decades, as Gartner asserts, a cloud security gateway may assist enterprises in securing digital assets now.

As you investigate your alternatives, you’ll see that suppliers implement these “security policy enforcement points” in a variety of methods and do not always centralize the same sorts of policy enforcement.

In other words, no one set of cloud security services is sufficient to establish a cloud security gateway.

The uncertainty here reflects the fact that the cloud widens a business’s IT perimeter in ways that are redefined year after year. Just as next-generation firewalls swiftly established themselves as a distinct product category, cloud security gateways are following suit.

Understanding the differences between cloud security gateways on the market today can assist you in identifying the product that offers the proper set of features for your business.

A Cloud Security Gateway’s Key Features

Cloud security gateways’ core functionalities were formerly available as standalone products or services, including the following:

CASB: A cloud access security broker acts as a middleman between users and cloud service providers, providing administrators with insight and control over their organizations’ cloud application usage. A CASB may discover and monitor any SaaS, PaaS, and IaaS resources that are connected, centralizing policy enforcement based on application risk or compliance requirements.

Data loss prevention (DLP) is a collection of tools and processes that safeguard sensitive data when it is at rest, in transit, in use, and on endpoints. To avoid data loss and theft, DLP solutions enable you to discover, classify, encrypt, mask, and tokenize your most sensitive data.

RBI: Remote browser isolation isolates a user’s web browsing activities from their endpoint device and other company resources through the use of virtualization. This safeguards users from dangerous websites and halts the propagation of threats.

SWG: A secure web gateway continuously inspects and filters internet traffic. It enforces administrator-defined policies to prevent data leaks and unauthorized access. Remote employees enjoy a secure connection regardless of their location.

ZTNA is a collection of technologies and rules that safeguard all traffic, both inside and beyond the perimeter, by assuming it is hostile. Across all environments, traffic is constantly re-authenticated and reauthorized.

Maintaining consistent, up-to-date policies is considerably easier with a cloud security gateway than with a hodgepodge of disparate solutions. You, and your employees, should not be concerned about the type of network from which they are attempting to connect.

If an attack occurs, you may trace it back to its source regardless of which environments it traversed. A cloud security gateway’s extensive audit trails can be linked with your SIEM, providing important information to your security team. In the long term, enhanced visibility results in a more carefully designed perimeter.

Vendors include additional threat protection into each capability by leveraging security intelligence from thousands of other users. New malicious methods discovered in one network swiftly result in platform-wide updates and strategies. The best cloud security gateways are updated on a regular basis to address emerging threats.

Perhaps the most critical aspect of a cloud security gateway is that it is purpose-built for the new job of perimeter protection. Each service works closely with the others as a holistic tool to provide threat analysis and response capabilities that would be unattainable with any single service.

Because many of the functionalities of cloud security gateways are already available, users of AWS, Azure, Google Cloud, and other platforms may be able to use their in-house cloud security solutions in place of cloud security gateways.

It is possible to deploy a hybrid “cloud security gateway” on AWS, given that your team possesses the necessary cloud security certifications and experience.

On the other hand, the best cloud security gateways are pre-configured to secure the complex relationships between the home office, data center, and cloud.

The fact that the majority of these products are associated with Amazon, Microsoft, Google, and other major cloud providers speaks much about their quality. For example, Forcepoint interfaces with Azure Sentinel, one of Microsoft’s flagship cloud security products, to provide robust investigation and response capabilities.

In a nutshell, all of these products are backed by the industry’s largest cloud service providers and cybersecurity suppliers. They are highly expandable, interacting with other cutting-edge technologies to safeguard edge locations, the Internet of Things, and unmanaged devices.

As remote work and cloud collaboration become more prevalent, businesses may leverage these well validated cloud security gateways to centralize supervision of the evolving IT environment.

Essentially, it consolidates the functions formerly separated amongst the company’s DLP, CASB, SWG, and RBI to establish a multifunctional gateway between users and the cloud services they use.
