Secure and scalable internet access, maintaining stability, providing robust technical support and ensuring consistent policy enforcement across various user locations
Pros and Cons
  • "This secure connection allows users to connect to the Zscaler VPN and access the resources on the office network, making it a highly valuable component of our system."
  • "Occasionally, issues arise in the LogStack by a third party, particularly for government websites accessed by numerous users."

What is our primary use case?

It ensures a secure online environment for our users, irrespective of their location. By routing all internet traffic through the Zscaler Cloud, users can browse safely, shielded from malicious content. Whether connected from the office or home network, Zscaler enforces our defined policies consistently.

Using ZPA VPN users can connect to internal Network in secured way. 

How has it helped my organization?

Our users experience a safe and secure internet connection, whether they are in the office or connecting via their home Wi-Fi network or a public network. The Zscaler policy governs their internet access consistently, eliminating the reliance on individual IPs.

What is most valuable?

We utilize a shared security VPN for users to establish a connection between their devices and the Zscaler Cloud, enabling them to access the office network. This secure connection allows users to connect to the Zscaler VPN and access the resources on the office network, making it a highly valuable component of our system.

What needs improvement?

Occasionally, issues arise particularly for government websites accessed by numerous users from all over country using Zscaler IP Range. This can trigger false positives, causing certain IP ranges to be perceived as a security threat or associated with malicious activities, resulting in blocks. In such instances, we often find ourselves waiting for the block to be lifted or having to engage with the concerned website administrators. This is where Zscaler's expertise becomes crucial in addressing false positive blocks, as these incidents might not necessarily indicate malicious intent but could be errors affecting access to the platform. Zscaler need to look into the solution, how Traffic getting generated towards such websites should not cross the threshold level of traffic getting generated from certain Zscaler IPs and getting resulted in block mode situation.

A flexible and scalable solution that is easy to implement and very easy to understand
Pros and Cons
  • "The policies are very easy to implement."
  • "The product must allow users to check logs for an entire year in the local console."

What is our primary use case?

We use the solution to restrict uploading over public sites. We control the users’ actions through DLP. Only users who have access can upload files. We manage multiple policies.

What is most valuable?

The policies are very easy to implement. It's very easy to understand. We have the option to assign time limits to the access we provide. For example, we can implement a policy for one year for a particular user. Once it expires, we can disable it.

What needs improvement?

We have some limitations while checking logs. The product must allow users to check logs for an entire year in the local console. Currently, we can check logs only for the previous three to four months.

Forcepoint provides multiple services separately, but Zscaler does not provide separate DLP. It will be good if Zscaler provides the DLP module separately.

For how long have I used the solution?

I have been using the solution for the last two years.

What do I think about the stability of the solution?

I rate the tool’s stability a ten out of ten.

What do I think about the scalability of the solution?

The tool is very scalable. I rate the scalability a ten out of ten. Approximately 5,200 people are using the solution in our organization.

Which solution did I use previously and why did I switch?

We are also using Forcepoint.

How was the initial setup?

The initial setup is very easy.

What's my experience with pricing, setup cost, and licensing?

The product is a little more expensive than other tools.

What other advice do I have?

We do not face any challenges with the product. If we have any problems, the vendor helps us. The product is everywhere. Everyone is using it. It's very, very flexible. It provides a single solution for multiple modules like DLP, proxy, and firewall. Overall, I rate the tool a ten out of ten.

Helps us authenticate our applications, providing a secure way to access the Internet from our work environment
Pros and Cons
  • "The most valuable features are the File Type Control and SSL bypass policies. We"
  • "There is some issue while accessing the portal. It takes too long."

What is our primary use case?

We use Zscaler Private Access to authenticate our applications, which provides a more secure way to access the Internet from our work environment. We have multiple policies for different types of users. When new users join the company, they authenticate the VPA application to access the Internet. We use SSL bypass policies, tenant restrictions policies, and Microsoft tenant cloud application policies. We also use File Type Control Policy for all categories of files, and our traffic goes to the WAPAC file and the application. We are using services as per the requirements of our clients.

What is most valuable?

The most valuable features are the File Type Control and SSL bypass policies. We have multiple options, such as very flexible policies and modules in Zscaler. We will define them based on our requirements and the active Internet. We also have geolocation users. For example, a user from Singapore moves to Dubai. When the user tries to access the Internet, Zscaler automatically detects the geolocation and drives our traffic to the other channel. There is no issue here. 

When using a Blue Coat, we have some problems. Sometimes, some of our users have some issues, but once we update the agent, the traffic goes to the current geolocation without any problems, and they can access it. Sometimes, we have some URL categories blocked in our environment, but HPE sometimes removes the block. We request that the vendor to remove the block from the correct URL category. They provide a suitable solution based on the findings.

What needs improvement?

There is some issue while accessing the portal. It takes too long. It will take longer if I am on the URL Cloud App category and switch to other tabs.

For how long have I used the solution?

I have been using Zscaler Private Access for five years.

What do I think about the stability of the solution?

If something happens, they have integration and they send notifications. I rate the solution’s stability a ten out of ten.

What do I think about the scalability of the solution?

If I need to switch the policy to another task, the solution takes time. I rate the solution’s scalability a nine out of ten.

Which solution did I use previously and why did I switch?

Compared to other proxies, such as Glook and IronPort, Zscaler Private Access is very easy to handle.

How was the initial setup?

The initial setup is easy. You need to configure the proxy tool for the network configuration. They can forward multiple services based on the client's requirements. If we need to use the VPA, we need to authenticate. It takes one day to implement the solution, but for smooth running, it takes around a month because of timely revision.

What's my experience with pricing, setup cost, and licensing?

The solution is expensive.

What other advice do I have?

The categorization issue is dependent on the end user. For example, if I am trying to access a categorized URL but need to access it for work, I should be able to request a change to the categorization. Forcepoint can change the categorization itself, or the client team can do it for me. This is enough to change the categorization to meet the requirements. Overall, I rate the solution a ten out of ten.

Which deployment model are you using for this solution?

On-premises

Good scalability features that ensure enhanced security and confidentiality of critical information
Pros and Cons
  • "Its impressive scalability allows the combination of multiple dictionaries and using them as one engine, resulting in narrower data loss gaps."
  • "The customers would benefit from more robust documentation and conversations around configurations, as it is slightly complex."

What is our primary use case?

We are currently using Zscaler Cloud DLP internally and it provides us with a robust and highly configurable Data Loss prevention engine, which meets our specific data handling needs.

How has it helped my organization?

We experienced many benefits, including improved visibility and the ability to identify vulnerabilities in existing configurations. Its impressive scalability allows the combination of multiple dictionaries and using them as one engine, resulting in narrower data loss gaps. There are significant enhancements in email and file confidentiality, particularly with integration to MCAS solution, which provides insights into permissions and access control for files stored in OneDrive and SharePoint.

What is most valuable?

The most valuable features are its robustness and high configurability, particularly in relation to existing DLP dictionaries. The ability to choose and utilize specific dictionaries for various purposes, such as credit card checks or monitoring file permissions and transmissions within the corporate network. The platform allows the administrator to monitor who is sharing files and who has access to them, providing a proactive approach to data security.

What needs improvement?

The customers would benefit from more robust documentation and conversations around configurations, as it is slightly complex. Also, there should be an option for acquiring DLP as a standalone product rather than bundling it with packages, as this would provide more flexibility for customers who only need specific features. They should also provide more reviews and guidance on selecting the best-rated engines and dictionaries, as well as facilitating reporting for DLP violations and integrations with other cloud storage solutions. 

For how long have I used the solution?

We have been using it for a year now.

What do I think about the stability of the solution?

Zscaler sells internet access, not specifically DLP, so we had to build a point of presence for our location in Kenya due to latency issues.

What do I think about the scalability of the solution?

It offers high scalability capabilities.

How are customer service and support?

We faced some issues regarding the business support from them due to the lack of knowledge and understanding of troubleshooting processes, which may be time-consuming. However, after we submitted the tickets, they did provide their support and eventually, solved our issues.

How would you rate customer service and support?

Neutral

Which solution did I use previously and why did I switch?

We tried a few different solutions, but we opted for Zscaler because we were already using other products from them.

What about the implementation team?

The implementation process was straightforward, with good support and training provided by Zscaler. We found it easy to roll out the cloud connectors and configure policies for DLP. The whole process took about three weeks with the help of three individuals, including myself.

What's my experience with pricing, setup cost, and licensing?

Zscaler DLP solution is expensive, with a fixed pricing structure that is billed annually and monthly. There are no additional costs for licenses.

What other advice do I have?

I would recommend having a clearly defined objective and goal, which would facilitate choosing and implementing the solution effectively. I would rate it nine out of ten.

Which deployment model are you using for this solution?

Hybrid Cloud

Highly scalable solution but insufficient granularity in blocking
Pros and Cons
  • "The scalability is pretty good."
  • "The granularity in blocking is not sufficient, as new domains are automatically blocked for 30 days without further information."

What needs improvement?

Zscaler functions as a kind of proxy, but they lack responsiveness when it comes to customer requests. The granularity in blocking is not sufficient. For example, when a new domain is detected, it is automatically blocked for 30 days. If there is no further information, it is added to the trusted list. Attackers are aware of this and take advantage of it. They set up a benign site, get it categorized as safe, and then introduce malicious content afterward. Trying to get the categories reassigned or realigned is a challenge, as Zscaler is not very responsive in addressing such issues. In my experience, compared to BlueCoat, Zscaler falls short in terms of responsiveness.

For how long have I used the solution?

I'm currently reviewing Zscaler for our organization. We implemented it about two years ago. It's part of our zero-trust architecture initiative. 

However, we need to compare it with NetScout. Zscaler has certain capabilities like SD-WAN, and the proxy is quite good. Although, I had to stop using SD-WAN because it wasn't integrating well with Microsoft or Kaspersky.

What do I think about the stability of the solution?

It is stable. In my experience of about five years, I have only encountered two problems caused by it. So, I wouldn't rate it a nine out of ten. It's generally stable, with occasional issues.

What do I think about the scalability of the solution?

The scalability is pretty good. I would give it an eight out of ten. However, their responsiveness to customer concerns is not as strong as other vendors I have worked with.

What was our ROI?

There is definitely an ROI. Before I joined my current company, it was implemented about a year and a half ago, and it significantly reduced noise and improved team visibility. The SOC has always been satisfied with its performance. 

So, I believe there has been a good return on investment compared to my company's previous solution, Fortinet, which wasn't very effective. We are very happy with Zscaler.

What's my experience with pricing, setup cost, and licensing?

When it was implemented, it beat the competition on price according to the two companies I know that have it.

What other advice do I have?

Overall, I would rate the solution a seven out of ten.

A comprehensive and flexible solution for digital experience monitoring and protecting against various threats with seamless integration, straightforward implementation and versatile security features
Pros and Cons
  • "The agent's versatility is notable, used for digital experience monitoring to collect valuable endpoint metrics for troubleshooting."
  • "Occasionally, there are certain delays in report generation."

What is our primary use case?

I primarily use it for conducting security incident investigations and generating security reports. It serves as a valuable tool in analyzing and responding to security events, and its capabilities are instrumental in producing comprehensive reports on the security status of the network.

How has it helped my organization?

It proved to be invaluable in addressing our challenge of not having a rigid perimeter. With employees working from various locations, the need to move away from VPN reliance became apparent. Following thorough assessments, we opted to continue using it as our cloud Web Access solution.

What is most valuable?

It stands out for its seamless integration with various security solutions, such as EDR, SOAR, etc. The implementation process is straightforward, requiring minimal ongoing maintenance. The desktop agent enhances endpoint protection against zero-day vulnerabilities, providing a safeguard until patches are released. Its adaptability extends beyond a single solution, allowing integration with different models and solutions. The alert detection system and additional security features add an extra layer of appeal. The flexibility to start with one aspect and expand within a single vendor is advantageous. The agent's versatility is notable, used for digital experience monitoring to collect valuable endpoint metrics for troubleshooting. The security browser function distinguishes between known safe sites and potentially suspicious ones, ensuring a secure browsing experience. Unfamiliar websites are run in the Zscaler Cloud, isolating them from the endpoint and preventing potential phishing or malicious scripts from reaching the user's device.

What needs improvement?

Occasionally, there are certain delays in report generation. Clicking on a link, I found myself waiting for an unpredictable duration—sometimes as long as thirty seconds to a minute—until the report was ready.

For how long have I used the solution?

I have been working with it for over a year.

What do I think about the stability of the solution?

There have been instances where certain software or applications on the user side didn't work smoothly. This posed an additional onboarding challenge, requiring collaboration with technical support to analyze logs, generate reports, and identify necessary exclusions or policies to rectify the issue. Once addressed, the applications resumed normal functioning.

What do I think about the scalability of the solution?

It's highly scalable, and I frequently receive notifications about new data center expansions. With around five thousand endpoints, I am not aware of any problems that have been discussed as requiring a change of solution.

What about the implementation team?

I gained access to the web console, and within an hour, I comprehended its capabilities, which I found appealing. Beyond predefined reports, the platform enables users to retrieve any imaginable information. Creating a visual search request is a straightforward process, delivering the required data through a user-friendly interface.

What was our ROI?

The implementation has effectively addressed numerous challenges related to ensuring a secure internet connection for users.

Which other solutions did I evaluate?

When we conducted assessments, Cisco and Microsoft were also considered. However, at that time, Cisco was in the initial stages of developing their solution, and Microsoft had just released their web security gateway.

What other advice do I have?

When making a decision, choosing a market leader is often advisable. While the initial cost may be slightly higher, the long-term savings in both time and money, as well as the reduction in operational costs, often outweigh the investment. Opting for a leading product can also mitigate potential issues and challenges that might arise with newer or less-established alternatives. Overall, I would rate it eight out of ten.
