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.

User access management and threat prevention are enhanced with user-friendly controls
The best features Zscaler Internet Access offers include application control, tenant segregation, and PoP center regions which have low availability zones. The internet access is very successful and bandwidth speed is excellent. It also has application-based control, URL-based control, and SSL inspection capabilities, which are very useful. Additionally, the in-depth CASB segregation is very beneficial to us. One unique feature I found helpful is the tenant level restrictions, which we use to only access our organization's tenant level mail IDs, drives, and specific tenant level access while restricting public access. Zscaler Internet Access has positively impacted our organization as we have noticed substantial outputs and income. It has improved our security environment control and endpoint protection. It prevents numerous web attacks through its AI/ML incorporated capability which identifies malware, threats, and viruses. It has a toggle button to enable features entirely at the tenant level for all users onboarded into Zscaler Internet Access, resulting in much better outcomes.

Quotes from Members

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

Pros

"When compared with other products, Webroot DNS Protection is the best to secure the end users."
"The installation is easy and doesn't take long. The program speedy and doesn't crash. It doesn't consume computer hardware or software."
"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."
"When compared with other products, Webroot DNS Protection is the best to secure the end users."
"DNS protection is valuable."
"I would recommend Webroot; it is a very good solution and a solid solution that keeps our computers protected."
"Almost everyone who uses it is happy about the product."
"The solution's most valuable features are its reliability and availability, measured by the number of ports it offers."
"The best thing about Zscaler Internet Access is the website filtering. In the UAE it's quite an important feature because most of the malware comes through the SQL injection and through downloads from websites. Zscaler helps protect against that."
"Whether you are in a hotel somewhere, or in Africa, it does not matter. You will get the Zscaler protection presence anywhere."
"Basically, the standard traditional model of a firewall becomes obsolete when you implement Zscaler."
"Zscaler covers all the features needed to replace a VPN or proxy solution; they are good, and they've been on the market for 15 years now, so they are mature enough."
"Zscaler, however, leads the local market in value versus functionality."
"Zscaler excels in security protection and the cloud is always up-to-date."
"We enjoy all of the proxy capabilities and the capability to integrate into the SIEM/SOC solution."
 

Cons

"Reporting is not done in real-time. Rather, it is done in 15-minute intervals."
"It needs to be more secure for production environments, currently, it is reliable and secure but as per new internet attacks, it should be ready with a proactive approach to eliminate attack chances."
"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 addresses a specific risk related to malicious sites but doesn't cover broader security aspects."
"It needs to be more secure for production environments."
"The reporting system needs improvement. They should make it so we can customize it so we can add, remove, or change its interface but they use a template."
"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."
"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."
"They block Zscaler IPs when the traffic origin is from Zscaler IPs. They've been blocked by certain government organizations so the end users are not able to visit those websites unless we ask them to unblock those IP. This is a bit problematic."
"Sometimes, support isn't available."
"The admin console needs improvement as it loads slowly and sometimes takes two to five minutes to open."
"The pricing is an issue. It is expensive if you have all of your users in the same location. It is expensive compared to other firewalls on the market."
"There are some performance issues when we add on additional controls."
"Zscaler does not provide dedicated IPs to each customer. Hence, they share a pool of IPs provided by Zscaler. There is a chance of blacklisting these IPs. I also do not like the multi-management portal."
"The response time and engagement model for technical support could be improved to handle complex outages more efficiently."
 

Pricing and Cost Advice

Information not available
"It is a few pounds per user per month."
"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"​Be aware that you will need to invest some time and money to adapt your environment for Zscaler (traffic redirection, software deployment, authentication, etc).​"
"The price is competitive. It's not cheap and it's not expensive."
"If we need any extra features, the price will increase."
"It is costlier than other solutions."
"Price-wise, the tool is reasonable compared to the other products in the market but it is not a very low-priced tool. The solution does provide value for money."
