Best Secure Web Gateway Vendors

Installing a secure web gateway (SWG) enables you to prevent unsecured internet traffic from entering your internal network. It screens network traffic (eg: downloads, content), blocks incoming threats, and prevents data loss to protect your corporate networks from web-based malware.

But how do you find a solution that’s worth your money?

The best security web gateway vendors have products that can easily filter or scan web content for viruses, spam, and other forms of malware on top of providing policy enforcement capabilities for compliant web browsing. They should also identify and block potentially dangerous URLs or web traffic.

To help you make the right choice, we’ve created a list of the five best secure web gateway vendors. Let’s take a look.

How to Pick Your Secure Web Gateway Vendors?

Below, we’ve compiled a step-by-step rundown to help select the best secure web gateway vendor for your network. 

Step 1: Educate Yourself About Potential Threats and Vulnerabilities to Your Network 

Businesses that know underlying threats and vulnerabilities to their systems find it easier to state the trajectory and source of the threats and control any damage down the line. 

How? When you have in-depth knowledge about what you’re dealing with, you plan better, which ultimately helps you come up with strong solutions. Therefore, before evaluating or opting for a specific secure web gateway vendor, find out what’s happening in your network and why.

Step 2: Evaluate Existing Measures and Tools

Once you’re finished analyzing potential threats and vulnerabilities to your network, review each tool you’ve already configured and the existing actions you’ve already taken to handle malicious traffic in your network.

If what you have in place isn’t sufficient, crosscheck what it will cost to bring everything up to speed. If that number exceeds your budget, narrow down your options to cloud-based secure web gateway vendors. If it doesn’t, you have more flexibility when choosing options.

Step 3: Find Out Your Infrastructure Bandwidth 

Unfortunately, you can’t just buy a secure web gateway product and expect it to work within your existing infrastructure. You may need to upgrade your resources and infrastructure to make the most out of a prospective secure web gateway product. 

You need to understand your bandwidth before choosing a vendor. If you face any trouble, get in touch with the customer support team for answers. This will also give you a feel of the level of support you can expect from the developers.

Step 4: Check Product Alignment

In most cases, businesses choose cloud-based secure Web gateway solutions. If that’s the case, you need to ensure you can meet your chosen tool’s requirements.

This means your existing processes and methods should work properly with the prospective vendor. This includes having access to the required support for hassle-free cloud-centric deployment. 

In addition, you need to check whether the tool can integrate with your existing local tools. Opt for a secure web gateway vendor that fulfills all these requirements and can reliably eliminate cyberattacks and malicious traffic to your corporate networks.
