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

"I would recommend Webroot; it is a very good solution and a solid solution that keeps our computers protected."
"Webroot excels in DNS protection, particularly in blocking malicious sites and phishing."
"The installation is easy and doesn't take long. The program speedy and doesn't crash. It doesn't consume computer hardware or software."
"Almost everyone who uses it is happy about the product."
"When compared with other products, Webroot DNS Protection is the best to secure the end users."
"When compared with other products, Webroot DNS Protection is the best to secure the end users."
"Almost everyone who uses it is happy about the product. I don't get any types of complaints from my clients."
"DNS protection is valuable."
"The scanning feature is impressive, because they do not introduce a big latency to the traffic."
"We enjoy all of the proxy capabilities and the capability to integrate into the SIEM/SOC solution."
"Overall, it's a good solution; we had very few issues during implementation, technical support is quite helpful and responsive once you get a hold of them, it has private access and has a lot of features inbuilt including DLP and CASB, and the solution is scalable and stable."
"I like the granularity of the control of all the traffic, including SSL inspection. I also like the fact that the user interface is intuitive. The latencies with Zscaler are minimal compared to those of any other competitor. Other competitors do not really have the global scale that Zscaler has and cannot promise low latencies."
"From the top to bottom, Zscaler Internet Access is a great security product that protects my end users and remote users in the cloud."
"Whether you are in a hotel somewhere, or in Africa, it does not matter. You will get the Zscaler protection presence anywhere."
"I would recommend Zscaler Internet Access due to its ease of use and deployment, with a user-friendly interface."
"The most valuable feature of Zscaler Internet Access is that it is a consolidated solution, it comes with many features, such as DLP."
 

Cons

"The price could be improved."
"It addresses a specific risk related to malicious sites but doesn't cover broader security aspects."
"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."
"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."
"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."
"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."
"​When you have appliances, SSL inspection is always a headache due to poor performance and/or lack of ciphers implemented. ​"
"Another thing that I would like to see is if Zscaler could have a separate product for direct access. I looked at a private access solution, but I understand there's a separate product that isn't integrated with this."
"The deployment process of Zscaler Cloud Connector needs to be more user-friendly."
"There are some performance issues when we add on additional controls."
"The main issue with Zscaler Internet Access is proxy IP detection, which sometimes makes sites inaccessible."
"It needs better integration with other applications. It takes a fair amount of regular activity to apply the by-passes because it is very strict in its restrictions and frequently you have to go in and open things up to allow the workforce to work."
"Zscaler Internet Access can improve by adding traffic filtering based on the DNS."
"The solution is quite expensive. It's around double what others are offering."
 

Pricing and Cost Advice

Information not available
"The tool is moderately priced."
"We have found the solution to be expensive."
"Zscaler is transparent about its pricing model."
"If we need any extra features, the price will increase."
"Licenses are available on a per-host basis. Some features like sandboxing require an additional fee, but most standard features are included in the license."
"It is quite expensive. It does its job, but it is quite expensive for what we need."
"The pricing is fair based on its competitive market."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
