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."
"DNS protection is valuable."
"Almost everyone who uses it is happy about the product. I don't get any types of complaints from my clients."
"I would recommend Webroot; it is a very good solution and a solid solution that keeps our computers protected."
"The installation is easy and doesn't take long. The program speedy and doesn't crash. It doesn't consume computer hardware or software."
"When compared with other products, Webroot DNS Protection is the best to secure the end users."
"Basically, the standard traditional model of a firewall becomes obsolete when you implement Zscaler."
"Zscaler Internet Access has positively impacted our organization by improving our overall security posture, providing better visibility into the internet traffic our employees access, and protecting users from web-based threats such as phishing websites, malicious downloads, and suspicious sites."
"One feature that is valuable to me from an implementation point of view is that it's very easy to implement."
"The VPN is valuable, as the whole technology is very different from a traditional VPN."
"There is no lag in service when accessing the internet."
"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."
"Zscaler has helped protect our employees wherever they are working, by delivering safe web access."
"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."
 

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."
"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."
"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."
"We'd like to have more plugins and integration."
"There are some performance issues when we add on additional controls."
"What could be improved in Zscaler Internet Access is its price. It could be cheaper."
"Zscaler is one solution. It's a good solution, but it doesn't do everything."
"Sometimes it's not easy to use during large deployments of workstations. It's a bottleneck from a network point of view."
"The scalability of Zscaler Internet Access rates at 7-8 in the majority of cases. However, I am currently working with a client that requires very high internet throughput, which has been challenging."
"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."
"I would like to see the ability to choose a pool of IPs for my company, set up rules based on them, and know that those IPs are not used by other companies."
 

Pricing and Cost Advice

Information not available
"The pricing for Zscaler Internet Access could be made cheaper."
"It is quite expensive. It does its job, but it is quite expensive for what we need."
"Our monthly fee is around R3000."
"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."
"Zscaler is transparent about its pricing model."
"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."
"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."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
