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

"Webroot excels in DNS protection, particularly in blocking malicious sites and phishing."
"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. 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."
"The installation is easy and doesn't take long. The program speedy and doesn't crash. It doesn't consume computer hardware or software."
"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."
"Stability-wise, I rate the solution a nine and a half out of ten...The setup phase was easy."
"The protection is most valuable."
"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."
"The solution's most valuable features are its reliability and availability, measured by the number of ports it offers."
"In terms of management and visibility, there is a single panel where you can configure the policies for your entire organisation worldwide."
"Zscaler Internet Access has positively impacted my organization by reducing the dependency on on-premises hardware and improving security posture, enabling faster user onboarding, and providing better performance for remote users."
"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."
 

Cons

"It needs to be more secure for production environments."
"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 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."
"The price could be improved."
"It also needs better integration with other applications as well. There are some restrictions."
"They should enhance the audit reporting feature."
"Do not expect to pay for the service and start using it, like Gmail. Zscaler requires a proper implementation to be done to make it successful."
"Zscale is providing a proxy IP, and most government sites will block traffic from a proxy. Also, we see some performance issues on the cloud side during DC failover."
"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."
"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."
"I believe, when you use Zscaler, you are not protected from all malware and malicious attacks, so you may need another tool just to cover these gaps."
"One thing that needs to be improved is their presence in China. I'm not sure if that's a Zscaler thing or if it's a problem with all vendors in this space, but it would be nice to have better coverage in China. This concern is a common one for vendors across the board when dealing with the Chinese market."
 

Pricing and Cost Advice

Information not available
"We have found the solution to be expensive."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"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."
"We pay around 6,500 INR per user per year, which is very expensive. I would rate Zscaler's pricing one out of five."
"The pricing is fair based on its competitive market."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"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."
"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."
