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.

Cloud security has transformed remote access and now supports zero trust for all users
The best features Zscaler Internet Access offers are Secure Web Gateway, URL filtering, SSL inspections, and policy-based access control. I find myself relying on Secure Web Gateway, URL filtering, SSL inspection, and policy-based access control the most because these are the main and top-most features I use regularly. Zscaler Internet Access has all of these types of features for securing all internet access and web inspections, allowing me to control all traffic through these features. Zscaler Internet Access features include a Secure Web Gateway for URL filtering, file type control, and inline SSL inspections. The second feature is a cloud firewall with Layer 3 to Layer 7 filtering control and stateful inspections. No hardware inspection or hardware firewall is required. I can also perform segmentations by users, location, and application. There is a cloud CASB solution available as well. Additionally, there is an advanced threat protection feature with signature-based behavioral detections, inline IPS, and zero-day threat protections. The cloud sandboxing solution scans unknown files and provides machine learning-based verdicts to prevent zero-day malware delivery in my environment. There is also a DNS security feature that provides DNS tunneling detections, malicious domain controls, and faster threat containment at the DNS layer. The data protection feature includes inline DLP and CASB-style cloud app control, data sovereignty enforcement, and browser isolation, which executes risky sites in isolated cloud browsers and prevents endpoint compromises. 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. It has resulted in a drop in security incidents related to web threats and improved visibility into user activity. An area for improvement includes fine-grained troubleshooting tools, better policy simulations, and optimizations around initial configuration complexity.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I would recommend Webroot; it is a very good solution and a solid solution that keeps our computers protected."
"Webroot excels in DNS protection, particularly in blocking malicious sites and phishing."
"When compared with other products, Webroot DNS Protection is the best to secure the end users."
"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."
"DNS protection is valuable."
"The solution is scalable, we have around 70,000 total users across various environments."
"It securely transfers internet connectivity seamlessly, without any problems or issues."
"Zscaler excels in security protection and the cloud is always up-to-date. It does not matter if you are a small or big organisation, you will receive the same security quality."
"The most valuable feature of Zscaler Internet Access is that it is a consolidated solution, it comes with many features, such as DLP."
"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."
"Zscalar Internet Access is for Internet security, like an Internet security gateway. I like how it runs seamlessly in the background with a single sign-on. The controls you can have on devices for Internet security are good, and it doesn't impact speed wherever you're connected. Overall, I think it's very good so far."
"The initial setup is very straightforward."
"Zscaler Internet Access integrates effectively, especially with the high-level IP services."
 

Cons

"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."
"The price could be improved."
"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, 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."
"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."
"The price of the solution could be improved."
"An improvement would be if they could provide an out-of-the-box experience, like 20 to 30 features all ready to go. In comparison, LogRhythm offers out-of-the-box features. With Zscaler Internet Access, there is firewall IPS, multiple security services, filtering, DLP, and CASB browser isolation. These are things that all users are going to be using. However, when an administrator or architect would start building this, I would definitely need to engage professional services to help clients do it."
"In terms of usage, here in the GCC, it's still growing a growing market, so the combination of DLP, data leak prevention, to a certain extent is fine. But what it requires is user-based access or role-based access. The solution needs to grow into that, which definitely takes time. There's not an easy way to integrate it, when you have a cloud-based solution."
"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."
"If they can also integrate with the multi-factor authentication to prompt users to do another, second-factor authentication, that would be ideal."
"Cloud App’s database should be improved."
"Another thing that I would like to see is if Zscaler could have a separate product for direct access. I looked at a private access solution, but I understand there's a separate product that isn't integrated with this."
 

Pricing and Cost Advice

Information not available
"The pricing is fair based on its competitive market."
"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."
"We have found the solution to be expensive."
"The price of Zscaler Internet Access should improve, it is expensive."
"The tool is moderately priced."
"If we need any extra features, the price will increase."
"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."
"It is costlier than other solutions."
