James Selby - PeerSpot reviewer
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

"Almost everyone who uses it is happy about the product. I don't get any types of complaints from my clients."
"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."
"DNS protection is valuable."
"When compared with other products, Webroot DNS Protection is the best to secure the end users."
"One on the main benefits is protection all time from anywhere."
"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 scanning feature is impressive, because they do not introduce a big latency to the traffic."
"The URL filtering has been the most valuable feature."
"The solution offers a distributed organization to master and to control all of the endpoints."
"The most valuable feature for me is the ability to see how my network and traffic looks with modules like analytics and insights."
"Stability-wise, I rate the solution a nine and a half out of ten...The setup phase was easy."
"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."
 

Cons

"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."
"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."
"The price could be improved."
"The solution's technical support needs to be improved, especially by offering a better support structure for different geographical areas."
"The performance needs improvement. Some areas create performance issues and, depending on the use cases, require reconfiguration to perform again."
"One feature I am missing is the ability to connect automatically to internal monitoring systems."
"In terms of user experience, it could be better."
"The response time and engagement model for technical support could be improved to handle complex outages more efficiently."
"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."
"We'd like to have more plugins and integration."
"​When you have appliances, SSL inspection is always a headache due to poor performance and/or lack of ciphers implemented. ​"
 

Pricing and Cost Advice

Information not available
"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."
"We pay around 6,500 INR per user per year, which is very expensive. I would rate Zscaler's pricing one out of five."
"If we need any extra features, the price will increase."
"It is quite expensive. It does its job, but it is quite expensive for what we need."
"The pricing for Zscaler Internet Access could be made cheaper."
"​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 solution is a little bit expensive. On a scale of one to five, I would rate it as a three."
"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."
