In today’s digital workplace, web security should be a priority—particularly for organizations with remote or hybrid employees that communicate with the company network over an internet connection. Infiltrating an unsecure home Wi-Fi network isn’t the only way a cybercriminal can gain access to your corporate network; they can also trick users into installing malware from malicious websites or entering their credentials into phishing pages. To prevent these types of attack, all businesses that require their users to access the internet should consider implementing a web security solution.
There are two parts to web security: securing your users’ internet activity, which we’ll focus on in this guide, and securing your users’ connection to the corporate network, which you can read more about in our guides to the top enterprise VPN solutions and the top zero trust network access (ZTNA) solutions.
To ensure your employees can browse securely, you should consider implementing a web filter or a remote browser isolation platform. Web filters, including DNS filters and Secure Web Gateways, block users from accessing known malicious websites—including phishing pages—and prevent users from downloading web-based viruses and malware onto their machines. Remote browser isolation platforms isolate users’ internet activities within a remote sandbox environment that’s detached from your local network. This enables users to experience normal, unhindered browsing, while ensuring that any malicious pages or downloads are contained within the remote server, so they never reach the user’s system.
In this article, we’ll explore the top ten web security solutions designed to protect your users’ internet activity. These include cloud-based Secure Web Gateways, DNS filtering solutions, and browser isolation platforms. We’ll give you some background information on the provider and the key features of each solution, as well as the type of customer that they are most suitable for.

FAQs
What Is Web Filtering?
There are two main types of web filtering solutions: cloud-based Secure Web Gateways (SWGs), and DNS filters. Secure Web Gateways scan for malicious website code and harmful URLs, then filter harmful websites, such as phishing pages, so that users can’t access them. SWGs also block web-based viruses and malware from being downloaded to the user’s machine.
DNS web filters sort internet traffic based on DNS lookups. All web pages have a unique IP address, which browsers connect to the domain name to be able to load the page. DNS filters sit between the browser and domain so that browsers can’t load malicious sites. Many DNS filtering platforms come with a pre-configured blacklist of harmful domains that can’t be accessed on protected networks.
What Is Remote Browser Isolation?
Remote browser isolation platforms isolate users’ internet activity in a secure sandbox environment that’s separated, or “isolated”, from the local network. They do this by executing web-based commands in a secure server, often called a “remote desktop”. This means that users can have a totally normal browsing experience without pages or downloads being blocked, because all of their activity is taking place in a secure remote location. So, if a user did try to download a malicious file, it would be denotated within the remote sandbox, causing no harm to your company’s network.
