Offers reasonable pricing and solid scalability in the enterprise context
In my limited experience with Webroot, it has shown good scalability, particularly in the enterprise context. When it comes to Webroot DNS, I find it to be a nice solution but prefer a more comprehensive approach. I lean towards XDR vendors that can integrate DNS protection into a unified dashboard, especially as traditional anti-malware solutions like Webroot face challenges with evolving threat actors. Currently, I have around 60,000 Webroot users for anti-malware, but for DNS protection, it is a fraction—about one or two percent—since some clients opt for other solutions. Traditional anti-malware technology is becoming less effective against sophisticated threats.

Helps maintain a consistent posture of internet security while getting rid of VPN and hovering into zero trust
There could be a better way for the tool to categorize the traffic. For example, the tool does exceptions and everything overall. If I want to give guest access or provide access to guest users or any other internet access and if it does not go through the SSL inspection because, in our company, we can't have the root certificate on a device that we don't manage, which can be called out as an exception or an exclusion, but that doesn't provide a proper reflection of the picture of what is happening in the environment. There are granularities bringing it down. The tool I used or still have is Zscaler Cloud Connector to protect the cloud environment, which can have a bit more user-friendly installation and setup, and it would help a lot. The deployment process of Zscaler Cloud Connector needs to be more user-friendly. Improvements are required in the exception category. For example, suppose I report on a monthly basis what the breaches and traffic violating the SSL inspection area are coming from. In that case, I may find that half of them may be coming through some guest network, meaning the tool doesn't differentiate between the guest or normal networks or the corporate networks. Having options to differentiate different networks would be ideal so that it can show a true picture of things to users, as half of the things in the tool are not in our control and are not of our concern.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The installation is easy and doesn't take long. The program speedy and doesn't crash. It doesn't consume computer hardware or software."
"DNS protection is valuable."
"When compared with other products, Webroot DNS Protection is the best to secure the end users."
"Webroot excels in DNS protection, particularly in blocking malicious sites and phishing."
"Almost everyone who uses it is happy about the product. I don't get any types of complaints from my clients."
"We like Zscaler's traffic filtering, web security, DLP, and IPS features. The real-time threat protection is excellent."
"Zscaler Internet Access is less expensive than competitors like Palo Alto, offering a premium service justified by security enhancements and cost-effective scalability."
"We use ZIA for outbound internet connectivity. The internet traffic of on-prem users will be directed to the ZIA cloud for security checks and web filtering."
"Tech support is good."
"I would recommend Zscaler Internet Access due to its ease of use and deployment, with a user-friendly interface."
"The users are at different locations, and Zscaler helps us to put the organization's central security controls on these roaming users."
"The most valuable features of Zscaler Internet Access are it's on the cloud, high network performance, and the interception of users is very easy."
"It is easy to set up the solution."
 

Cons

"The reporting system needs improvement. They should make is that we can customize it so we can add, remove or change its interface but they use a template. The reports cannot be changed."
"It needs to be more secure for production environments."
"It addresses a specific risk related to malicious sites but doesn't cover broader security aspects."
"Reporting is not done in real-time. Rather, it is done in 15-minute intervales. This is something that should be configurable by the admin."
"The price could be improved."
"One feature I am missing is the ability to connect automatically to internal monitoring systems."
"The reporting functionality could be a bit easier to use. There is a reporting function, but it's quite hard to do any good reporting, from a user-management perspective. For example, if a department manager wants to know how his department is using the web, there is a way to get the data, but it's quite cumbersome to get it and show it well. And that's true for comparing between departments."
"​When you have appliances, SSL inspection is always a headache due to poor performance and/or lack of ciphers implemented. ​"
"Technical support could be better."
"There are some performance issues when we add on additional controls."
"Zscaler Internet Access's troubleshooting is very limited, and their textbook logs need to be more informative."
"The performance needs improvement. Some areas create performance issues and, depending on the use cases, require reconfiguration to perform again."
"Sometimes it's not easy to use during large deployments of workstations."
