In today’s digital workplace, we use the internet constantly. It allows us to find information in seconds that otherwise could take weeks of research to procure, and has opened up a world of virtual communication, allowing remote or hybrid teams to perform as effectively as collocated teams. But our reliance on the internet also makes us vulnerable to web-based threats such as malware, phishing, and Man-in-the-Middle (MitM) attacks.
Web security should be a priority for any business, and particularly those with remote workers who communicate over an internet connection. When one connection is compromised, it can take minutes for bad actors to spread malware through a company’s network. We’ve explored the most effective types of web security, and found that the best solutions fall into two categories: web filtering and browser isolation.
There are two main types of web filtering: cloud-based and DNS. Cloud web filtering platforms, or “Secure Web Gateways” (SWGs), filter harmful websites and block web-based viruses and malware from being downloaded to the user’s machine. They scan for malicious website code, filter harmful URLs, and prevent data loss.
DNS web filtering platforms sort internet traffic based on DNS lookups. Every webpage has 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.
The second type of web security we’ve explored is browser isolation. Browser isolation platforms isolate users’ online browsing activity in a safe environment that’s detached from the local network. The best browser isolation solutions are cloud-based and execute web-based commands in a secure server, or “remote desktop”. When using this remote desktop, the user experiences totally normal browsing, but it takes place independent of their local machine. This means that malicious webpages and attachments are contained or sandboxed within the virtual environment and never reach the user’s local system.
In this article, we’ll explore the top ten web security solutions, including a range of cloud-based and DNS filtering solutions as well as 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.
