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."
"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."
"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."
"The data loss prevention feature is the most valuable. It stops our users from inadvertently leaking our customers' data to the Internet or anywhere else it shouldn't go."
"Zscaler Internet Access is less expensive than competitors like Palo Alto, offering a premium service justified by security enhancements and cost-effective scalability."
"The initial setup was straightforward. The biggest thing for us was to build our own policies. The deployment itself was only a few hours."
"The solution’s customer service is good."
"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."
"We like Zscaler's traffic filtering, web security, DLP, and IPS features. The real-time threat protection is excellent."
"One on the main benefits is protection all time from anywhere."
 

Cons

"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."
"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."
"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."
"The price could be improved."
"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."
"It also needs better integration with other applications as well. There are some restrictions."
"Zscaler needs to add client-to-client communication. It's always client-to-server communication. The cloud and branch connectors could be improved because we're still dependent on traditional firewalls. They should eliminate this. They should also provide WAN devices should to compete with the SD-WAN solutions also."
"They could provide more time for the onboarding the training of an IT person."
"They should enhance the audit reporting feature."
"The response time and engagement model for technical support could be improved to handle complex outages more efficiently."
"I would like to see more training and video documentation."
"There are a few features that are not compatible with the Azure cloud."
 

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."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"The price of Zscaler Internet Access should improve, it is expensive."
"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."
"It is quite expensive. It does its job, but it is quite expensive for what we need."
"It is a few pounds per user per month."
"​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 pricing is an issue. It is expensive compared to other firewalls on the market."
