Deputy GM - IT at a manufacturing company with 1,001-5,000 employees
Designed to provide comprehensive and secure internet access with high visibility into users
After my purchase, I noticed a need for improvements, particularly in the area of identifying the source user of the device, which can sometimes roll back to the base. Additionally, there were challenges with SSL gate traffic, which wasn't functioning as effectively as expected. Even though there have been fixes to these issues, they should be inherent to the product and need further attention. These aspects, especially sub-features, aren't very robust and seem complex. Regarding integration, while Sangfor Internet Access Gateway (IAG) integrates well with its own products, its compatibility with third-party tools like QB is limited. There's room for improvement in making protocols compatible with various third-party products.

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

"The most significant aspect is the control it offers over internet traffic, like managing computer access to specific sites such as Facebook. I find particular value in its ability to control the depth of internal traffic, enabling actions like blocking specific file extensions on social media or specific IPs. This control by categories is a standout feature for us in Sangfor Internet Access Gateway (IAG)."
"The solution is interoperable and has centralized management."
"Stability-wise, I rate the solution a ten out of ten."
"Zscaler Internet Access's roaming user feature is most valuable and is much better compared to other secure web gateways."
"It securely transfers internet connectivity seamlessly, without any problems or issues."
"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."
"Tech support is good."
"The most valuable feature is bandwidth control."
"There is no lag in service when accessing the internet."
"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 scanning feature is impressive, because they do not introduce a big latency to the traffic."
 

Cons

"In Sangfor Internet Access Gateway (IAG), its speed is an area of concern where improvements are required."
"After my purchase, I noticed a need for improvements, particularly in the area of identifying the source user of the device, which can sometimes roll back to the base. Additionally, there were challenges with SSL gate traffic, which wasn't functioning as effectively as expected. Even though there have been fixes to these issues, they should be inherent to the product and need further attention. These aspects, especially sub-features, aren't very robust and seem complex. Regarding integration, while Sangfor Internet Access Gateway (IAG) integrates well with their own products, its compatibility with third-party tools like QB is limited. There's room for improvement in making protocols compatible with various third-party products."
"The solution's logging system should be improved because its logs are not precise and are a little confusing."
"​When you have appliances, SSL inspection is always a headache due to poor performance and/or lack of ciphers implemented. ​"
"Sometimes, support isn't available."
"The admin console needs improvement as it loads slowly and sometimes takes two to five minutes to open."
"Cloud App’s database should be improved."
"The main issue with Zscaler Internet Access is proxy IP detection, which sometimes makes sites inaccessible."
"We'd like for them to include some sort of antivirus tool."
"The interface for administration could be better. They should upgrade the management portal."
"The solution's pricing is on the higher side. It would be better if it could be lower."
 

Pricing and Cost Advice

"It is one of the reason for choosing it over other available products. However, recently, this year, there have been recurring concerns. I believe we might consider migrating to another solution."
"The solution’s pricing is cheaper than any other solution."
"I rate the product pricing a five or six out of ten on a scale of one to ten."
"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."
"The pricing for Zscaler Internet Access could be made cheaper."
"The price is competitive. It's not cheap and it's not expensive."
"The pricing is an issue. It is expensive compared to other firewalls on the market."
"​Be aware that you will need to invest some time and money to adapt your environment for Zscaler (traffic redirection, software deployment, authentication, etc).​"
"Zscaler is transparent about its pricing model."
"The price of Zscaler Internet Access should improve, it is expensive."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
