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."
"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."
"When compared with other products, Webroot DNS Protection is the best to secure the end users."
"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."
"The users are at different locations, and Zscaler helps us to put the organization's central security controls on these roaming users."
"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."
"It is easy to set up the solution."
"The solution is scalable and stable."
"Zscaler has helped to reduce the time we spend managing security policies, significantly lowered the number of FTEs needed to manage the environment, and has definitely helped reduce the number of infected devices in our organization by proactively preventing attacks."
"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 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."
"It's easy to deploy and easy to use."
 

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, 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."
"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."
"The tool should improve the predefined dictionaries."
"One feature I am missing is the ability to connect automatically to internal monitoring systems."
"Do not expect to pay for the service and start using it, like Gmail. Zscaler requires a proper implementation to be done to make it successful."
"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 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 price of the solution could be improved."
"Zscaler is one solution. It's a good solution, but it doesn't do everything."
"They should enhance the audit reporting feature."
 

Pricing and Cost Advice

Information not available
"Our monthly fee is around R3000."
"It is quite expensive. It does its job, but it is quite expensive for what we need."
"There are multiple bundles: enterprise, business, and transformation. Transformation includes all the features, but recently I've seen a few more line items that are additional costs. Overall, it's expensive."
"It is costlier than other solutions."
"​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 price of Zscaler Internet Access should improve, it is expensive."
"The price is competitive. It's not cheap and it's not expensive."
"If we need any extra features, the price will increase."
