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.

"Almost everyone who uses it is happy about the product. I don't get any types of complaints from my clients."
"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 is stable."
"The most valuable feature is the ability to drop packets."
"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 our organization as we have noticed substantial outputs and income, improved our security environment control and endpoint protection, and it prevents numerous web attacks through its AI/ML incorporated capability which identifies malware, threats, and viruses."
"All internet access flows through the Zscaler proxy, regardless of whether people are in office or remote. I have greater control site access and I minimize the number of compromises that we experience to almost none."
"Zscaler, on the other hand, is more stable and also more secure."
"We like Zscaler's traffic filtering, web security, DLP, and IPS features. The real-time threat protection is excellent."
 

Cons

"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."
"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."
"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 price could be improved."
"Zscaler should provide adjacent services, which would be complementary to their current offering that could be more pragmatic for a customer."
"Zscaler is one solution. It's a good solution, but it doesn't do everything."
"The price of the solution could be improved."
"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."
"The tool should improve the predefined dictionaries."
"In terms of user experience, it could be better."
"The main issue with Zscaler Internet Access is proxy IP detection, which sometimes makes sites inaccessible."
"Sometimes, support isn't available."
