SWGs keep an eye on incoming internet traffic and stop threats like malware, phishing scams, and viruses from getting into the company’s internal network. They also perform MITM inspection on SSL-encrypted traffic in order to prevent hackers from avoiding detection. An efficient SWG can monitor employee online activity and help IT and security teams stop data leaks from authorized applications by limiting the size of files that can be uploaded. This feature helps ensure that employees use only approved cloud applications for work.
Protect Your Network From Malware
Because more and more work is being done remotely, employees must have access to a secure internet network. A secure web gateway (SWG), which filters out harmful content from internet traffic and confirms the security of any downloaded files, makes this possible. This helps to lessen the impact of data breaches and cyberattacks. Similar to a proxy server, a SWG serves as a firewall between end users and the network. It scans inline web traffic and protects the business from malware, viruses, and phishing attempts by looking over incoming and outgoing data. It also offers data loss prevention (DLP), which enforces adherence to corporate and legal policies by intercepting and blocking any unauthorized data transfer.
To serve as SaaS gateways, SWGs can be deployed in hardware appliances or the cloud. Both cloud-based SWGs for remote workers and hardware appliances for offices are used by many businesses. Regardless of the kind of SWG you have, staying current with security updates and new features is crucial to ensuring your protections are always up to date. Additionally, in order to identify and prevent any malicious content from entering the network, the SWG inspects SSL/TLS encrypted data using the Mean Inversion Technique (MITM).
Adopt Internet Usage Policy
For the layered defense against web-based threats to be effective, multiple devices must work together. Among those devices are SWGs, or secure web gateways. It might be a hardware or software solution for the network perimeter, endpoints, or the cloud. A SWG monitors traffic to and from the internet to enforce acceptable use policies for cloud apps and websites. SWG security uses a variety of tools and methods, including content inspection, URL filtering, and antimalware protection, to find potential threats. Depending on the vendor, some SWGs may include data loss prevention, which intercepts outgoing communications containing sensitive information like security credentials or controlled documents like engineering drawings.
Your security monitoring solutions, such as SIEM and NGFW, can be integrated with a SWG to guarantee that you are notified of any issues as soon as they occur. For detection and prevention, it can also be integrated with your zero-day antimalware program. Certain SWGs can also be integrated with your threat intelligence feeds to provide you with an alert whenever new threats and attacks appear online. A SWG can also include a remote browser isolation (RBI) solution to prevent malicious code and data from entering the organizational network. RBI solutions run all active principles in a disposable virtual container outside the regular endpoint browser.
In addition to lowering risk and protecting data, this lets employees continue using their favorite apps without interfering with work.
Turn Off Unauthorized Internet Apps
A secure web gateway (SWG) uses a range of technologies, including URL filtering, SSL inspection, antimalware protection, content inspection, and threat detection, to identify potential threats like malware and phishing. Furthermore, it implements organizational security policies, like website blocking and department- and role-based app access limitations. SWGs provide a layered defense against malware and phishing attacks, assist in adhering to legal requirements such as GDPR and HIPAA, and prevent sensitive data from being transferred over the internet without authorization. They can be configured as on-site hardware or software appliances, or as cloud-based services.
Next Gen SWGs allow you to monitor user behavior on apps and cloud services, establish comprehensive acceptable use policies, trigger risk-adaptive processes based on context, activity, and app and user risk, warn users away from risky apps, and encrypt or redact sensitive data. They also help with real-time data loss prevention (DLP), which finds and stops illegal data from leaving the company’s network. With the help of this new feature, you can automatically mark apps and domains as unsanctioned in the Microsoft Defender ATP Indicators experience and block apps on endpoint devices.
This automatic blocking will take effect if you have manually configured organizational scoping on indicators. These tags have the potential to spread throughout all endpoint devices and disable the relevant Microsoft Windows Defender SmartScreen applications over a period of up to two hours.

Since employees must access websites and cloud apps to carry out their jobs, a successful business must place a high priority on security. However, traditional network infrastructures are no longer useful for this purpose because they were designed to protect a perimeter-based network and are not suitable for the demands of today’s cloud-based environment. By enforcing internet usage policies and protecting businesses from cyberattacks, SWG solutions bridge this gap. SWG solutions monitor web traffic to identify potential threats, such as malware or phishing, and enforce organizational policies, such as content blocking. To identify these threats, they use a variety of techniques, including URL filtering, content inspection, SSL/TLS inspection, antivirus and antimalware protection, and more.
They can also contain user behavior analytics (UBA) to spot questionable user activity patterns and data loss prevention (DLP) to prevent sensitive data from leaving the system.
While SWG solutions can be deployed as hardware appliances, most businesses prefer cloud-based gateway solutions. This offers many organizations a more affordable and flexible option. By eliminating the need to replace outdated hardware, it also saves the business money and downtime. Companies that have already made hardware investments may also opt for a hybrid solution that blends on-premises and cloud-based SWG features. They can thus benefit from the best feature of each deployment method without having to incur the technical debt associated with out-of-date firewall architectures.
