Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

Secure Web Gateway (SWG) is an excellent approach to protect your data and implement your security policies.

As cyberattacks are increasing, many security solutions seem to fail against them. Not only big businesses but also small and medium-sized businesses are impacted due to such risks.

Data breaches, malware attacks, and other deadly cyberthreats are posing greater risks to businesses and consumers alike.

Therefore, implementing a better, advanced solution that can combat such issues and avert them is important.

Secure web gateways are one such technology. 

In this article, we will understand what SWG is, its capabilities, and some of the best SWG solutions you can look up to.

What Is a Secure Web Gateway (SWG)?

A Secure Web Gateway (SWG) is a cybersecurity solution that protects systems and data and helps enforce security policies in a company. It filters malware and harmful content from internet traffic to stop data breaches and cyber-attacks and blocks unauthorized users.  

An SWG ensures the users access only approved and secure sites while blocking the rest. It comes with advanced security capabilities to detect and restrict malicious traffic. Some sophisticated SWG can also protect an organization’s sensitive data such as personal information, confidential documents, intellectual property, etc.

Features of SWG

Secure web gateway solutions usually contain technologies and features like: 

  • URL filtering 
  • Application control 
  • Anti-malware scanning and blocking
  • Content filtering
  • Data loss prevention (DLP)
  • SSL inspection
  • Social media prevention
  • Multiple protocol support
  • Integration with security solutions like zero-day solutions, anti-malware software, monitoring tools, etc.

How Does a Secure Web Gateway Work?

Secure web gateway solutions are installed as a hardware device or software component at user endpoints or on a network’s edge. SWG solutions can be of different types:

  • Software-based SWG: It runs in the cloud as a SaaS-based application or on an organization’s premises.
  • SWG running on a proxy server: It can be a virtual machine (VM) running in the cloud or a physical server located at a place
  • SWG running as on-premise devices: It can be a hardware system connected to an organization’s IT infrastructure.

Irrespective of how they are deployed or run, each type of SWG works in a similar fashion. It acts as a gatekeeper and monitors web traffic for risks, malicious content, URLs, etc. And all the incoming and outgoing web traffic must pass through this gateway.

In order to differentiate bad vs. good traffic, it maintains a list of approved and known sites and permits traffic from those sites while blocking all the others. This list is secured in the SWG solution’s database and applies the filters when web traffic tries entering or leaving an organization’s network.

For example, when a user tries to access a site, this request first goes to the SWG instead of directly reaching the targeted site. At this time, the gateway or SWG solution inspects this request by checking it against the accepted list and security policies. The SWG passes the request only if it falls under the list and doesn’t violate any security rule.

For outgoing traffic, a similar pattern is followed. When someone tries accessing your network or site, the SWG in use will inspect this request against its set of security rules and allowed list. If the request seems legitimate, the SWG will permit the traffic to pass; otherwise, it blocks it right there so it cannot reach your network or systems and infiltrate your data. This way, the SWG helps protect your data, systems, network, and other digital assets.

Why do Businesses Need SWG?

Enterprises both big and small need a secure web gateway due to its advanced security capabilities.

Traditionally, businesses used to run only on-premises systems using just the internal network. Today, the business scenario is changed. Now, people are working from anywhere using any device, system, and network. Also, businesses are relying heavily on cloud computation for services and solutions that can help companies automate tasks and increase flexibility, productivity, and speed.

Although these technologies have increased convenience and given plenty of benefits, cybersecurity risks have expanded further. Cyber attackers are finding new and improved ways to infiltrate your systems and steal data and damage your reputation and customer trust.

Hence, technologies like SWG are highly useful for every business type since no one is safe these days, irrespective of business size. SWG can be deployed and run anywhere and provide security everywhere. Here are the various benefits it can provide businesses with:

Detecting and Preventing Cyberthreats

Web traffic can bypass security solutions such as firewalls.

But an SWG solution has capabilities to detect potential threats, malicious code, vulnerable data, etc., easily that are embedded in web content. An SWG via a poxy can monitor complete sessions carefully to find violations and harmful agents.

SWG may include evolving attack signatures dynamically to increase its detection capability. It can also offer the latest web intelligence correlating with endpoints, emails, records, files, etc., to create threat profiles. This way, it can provide all-around protection from cyber threats.

Exposing Harmful Encrypted Traffic

Secure sockets layer (SSL)-based web traffic is increasing, and a large amount of this data is not generally analyzed for threats and policy violations. However, attackers can use encryption to hide malware and deploy their harmful intent.

SWG solutions come with an SSL inspection feature to monitor and block harmful code encrypted in web traffic. This way, you get superior protection.

Better Security Control

You can visualize and control your traffic better using an SWG solution since it has advanced capabilities. It can log events continuously and monitor all the activity happening in your network.

This helps you get superior control and protection over your network. In addition, if you have a remote workforce with employees and contractors working from any part of the world, SWG will be beneficial since you can deploy it anywhere.

Maintaining Compliance

Data privacy is a big concern due to increased cybersecurity issues like data breaches. There are also people that sell personal information illegitimately to other parties for their financial gains. All these pose harmful impacts on businesses and people due to their exposed data. Using SWG, you can protect your data as it monitors web traffic 24/7 and prevents risks.

Maximizing security ROI

You can integrate SWG solutions with other security solutions such as monitoring tools, anti-malware software, etc. It also extends across environments from on-premise to cloud. Hence, you can utilize your current security tools in combination with an SWG solution. It will help you maximize your security investments. 

So, if you are looking for the best secure web gateway solution, here are some of our recommendations.
