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."
"When compared with other products, Webroot DNS Protection is the best to secure the end users."
"DNS protection is valuable."
"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."
"We like Zscaler's traffic filtering, web security, DLP, and IPS features. The real-time threat protection is excellent."
"Zscaler, on the other hand, is more stable and also more secure."
"The solution’s customer service is good."
"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."
"What I like most about Zscaler Web Security is that we can have our users protected from internet threats and viruses even when they're not connected to our network."
"I would recommend Zscaler Internet Access due to its ease of use and deployment, with a user-friendly interface."
"Zscaler is an expensive solution, but it's worth the price."
"Zscaler Internet Access protects using data loss prevention. If you have a CASB exposing your cloud out into the network, then Zscaler Internet Access will go ahead and control that unknown cloud application in the CASB, protecting it. There is also data detection with exact data match. This improves the data coming into your cloud so you are protecting it."
 

Cons

"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."
"The price could be improved."
"It needs to be more secure for production environments."
"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."
"I don't know whether it's Zscaler or not, however, sometimes I can't access my time management. I need to wait and try again a few hours later. Typically, if I let some time pass, I can access it again."
"I would like to see more training and video documentation."
"Zscaler Internet Access could improve by adding a VPN feature."
"In terms of user experience, it could be better."
"Zscaler should provide adjacent services, which would be complementary to their current offering that could to be more pragmatic for a customer. For example, if you take Akamai, you get multiple sets of services, all depending on the customer and the strategy and the complexity and the problems. In some areas, they are more varied in terms of coverage."
"There are some performance issues when we add on additional controls."
"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."
"It also needs better integration with other applications as well. There are some restrictions."
 

Pricing and Cost Advice

Information not available
"Zscaler is an expensive solution, but it's worth the price. Their services are unmatched by competitors. Some may come with half the features that Zscaler can offer and be much cheaper. However, they do not have the global coverage that Zscaler has, and they will not provide the same low latencies and the same speeds that Zscaler can."
"There are multiple bundles: enterprise, business, and transformation. Transformation includes all the features, but recently I've seen a few more line items that are additional costs. Overall, it's expensive."
"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."
"The price of Zscaler Internet Access should improve, it is expensive."
"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."
"The tool is moderately priced."
"The pricing for Zscaler Internet Access could be made cheaper."
"The price is competitive. It's not cheap and it's not expensive."
