Snr Presales Cyber Security Engineer: Palo Alto| F5 at Westcon-Comstor
Comprehensive and scalable security, seamlessly integrating with diverse network environments, providing consistent protection, and adapting to the evolving landscape of cloud adoption
Pros and Cons
- "The most valuable feature is its seamless integration capabilities, streamlining the process by eliminating the need for extensive installations."
- "Having a Zscaler-specific device could streamline this process and provide a more consistent user experience across diverse branches."
What is our primary use case?
It serves as a globally distributed solution, differing significantly from MPLS. Unlike traditional firewalls, it seamlessly accommodates cloud services and enables remote work from any location. The product's global distribution across the cloud facilitates internal access with the necessary licenses. Whether connecting from a branch office, on-premises solution, private data system, public data center, or the cloud, the platform ensures consistent and robust security protection throughout the entire infrastructure.
What is most valuable?
The most valuable feature is its seamless integration capabilities, streamlining the process by eliminating the need for extensive installations. Users can connect to the SaaS solution by simply installing the necessary apps. This includes the flexibility to connect with any firewall or router capable of setting up IPSec, providing users the freedom to choose their preferred hardware. This versatility extends beyond Zscaler-specific applications or devices, making it compatible with a range of SD-WAN solutions, such as Cisco Meraki, Palo Alto, and Juniper.
What needs improvement?
A suggestion for improvement is the development of their own proprietary SD-WAN device. Currently, the experience can vary when integrating cloud protection with different vendors, such as Palo Alto, Meraki, or Juniper. Having a Zscaler-specific device could streamline this process and provide a more consistent user experience across diverse branches. Additionally, expanding their offerings to include solutions like SIEM, similar to competitors, could enhance their portfolio and cater to clients interested in a broader range of services.
For how long have I used the solution?
I have been working with it for two years.
What do I think about the stability of the solution?
It is highly reliable and ensures that users receive optimal performance regardless of their physical location, creating a more seamless and user-friendly experience.
How was the initial setup?
The initial setup was straightforward.
What's my experience with pricing, setup cost, and licensing?
The perception of cloud services being expensive is often a result of the initial migration costs, especially when transitioning from traditional and limited MPLS environments. In the long run, cloud services are not inherently costly. If you're starting fresh and adopting a cloud-first approach from the beginning, the perceived expense is considerably less significant.
What other advice do I have?
It is not economically viable for individual users but is highly recommended for companies with a substantial user base, multiple branches, extensive cloud operations, and remote employees. The solution offers enhanced protection across network, on-premises, and cloud environments, making it valuable for enterprises adapting to the evolving landscape of cloud adoption and seeking comprehensive security and networking benefits. Overall, I would rate it nine out of ten.
Disclosure: My company has a business relationship with this vendor other than being a customer:
Security Architect at a comms service provider with 201-500 employees
Stable with good pricing and very good for monitoring sensitive data
Pros and Cons
- "You can close your data protection gaps with Zscaler. You can quickly find all the classified, sensitive data across the cloud."
- "There aren't really any missing features that I have witnessed."
What is our primary use case?
Unlike unconventional data that's being exposed, data loss prevention can become very difficult. Several of the old technologies, such as Symantec and McAfee, can cause a range of problems. On top of that, it derives from a lot of fines for customer loss. You can go through legal ramifications and damage to your company brand when data is exposed. Zscaler creates a significant bypass of security controls. It helps you with your compliance. Basically, it will then help you protect sensitive data.
Zscaler's Cloud DLP will also assist the users off-network, protecting them against data loss. The Cloud DLP will inspect all the traffic including SSL, which will give you protection and visibility. Zscaler Cloud DLP will also allow for compliance. It'll give you compliance for all major regulations that you have to go through.
What is most valuable?
Their technology can monitor and inspect data on the corporate level. It protects all the sensitive data from within the organization. You could definitely review anything that is on the network and verify the DLP tools by setting alerts and rules in order to mitigate risks such as losing your customers' PAI.
It's a pretty solid solution.
It connects to the cloud, so it's really fast. It obviously is going to bypass the gateway, give you security controls, and also allows SSL traffic to be hidden.
You can close your data protection gaps with Zscaler. You can quickly find all the classified, sensitive data across the cloud. You can also have protection using advanced features like Exact Data Match, and that's document matching as well as machine learning.
The pricing of the solution is very good.
The solution is very stable.
The initial setup is pretty straightforward.
The product scales well.
Zscaler is an integrated platform, so it's fully integrated with zero-day protection to all the users working from home or in our offsite network, and it's going to make customers close that security gap.
What needs improvement?
Zscaler will protect PII for all users regardless of their geolocations as well it will simplify compliance requirement's by eliminating complexity of legacy systems and securing your cloud data across all channels data in motion, at rest,
and across endpoints and clouds.
For how long have I used the solution?
I've been dealing with the solution for almost two years at this point.
What do I think about the stability of the solution?
The stability is good. Every function of the Zscaler DLP performs very quickly. It's very stable, and it's powered by AI. When it comes to threat and data leakage, it's on a packet-by-packet basis. You have a zero-trust exchange and it's a complete data loss prevention or protection package. It does a full inline inspection, including SSL and TLS traffic.
What do I think about the scalability of the solution?
The scalability is good. The transformation for scalability is based on IT operations. It is easy to add and deploy from branches. It will reduce the architecture for MTLS cost without adding any burden to the actual upgrade of your deployment.
How are customer service and technical support?
I haven't directly dealt with technical support. I can't speak to how helpful or responsive they are as I have no direct experience with them.
Which solution did I use previously and why did I switch?
I've previously used Symantec SLP. That was a couple of years ago.
There are a few key differentiators for Zscaler. Obviously, it's faster, and it's secured. You're routing traffic directly to the internet when you use Zscaler, and in that way, you are reducing cost. There is no reason to spend a lot of money on MPLS. There is no need to buy that. You could deploy and manage security appliances or any new generation firewalls on each branch, and you're providing more security without compromising cost. You're centralizing an overall zero-trust architecture by enforcing policies just a few clicks away.
How was the initial setup?
The good thing about the setup is you don't really need hardware appliances to deploy it. All you need to do is connect your Zscaler services, which is pretty simple, and forward all of your internet traffic to the Zscaler services. That's how you secure all your internet traffic. You can apply policies accordingly.
What's my experience with pricing, setup cost, and licensing?
As far as the pricing, it's very competitive. The more users you have, the cheaper it ends up being annually.
Let's say you have 100 users, it'll cost $39.69 a user. And if you have 10,000 users, it will cost you $19.15 per user. The more users you have, the cheaper they are individually. If you have a ZIA Professional bundle, the pricing is pretty affordable.
The struggle from old IT infrastructure is that you're dealing with a lot of legacy hub-and-spoke architecture and companies used to spend a lot of money on MPLS say 10, five years ago. If you're using old technology and your on-premise, you're forcing to pay twice for your internet-bound traffic. Those are the reasons why customers are rethinking their current solutions and moving to an easy solution like Zscaler in a cloud.
What other advice do I have?
I'm a reseller.
I'd rate the solution at a nine out of ten. I'd advise that this is one of the layers of security that most people need to have.

Network and Security Engineer at a security firm with 11-50 employees
A cloud solution for security features like encryption, URL filtering, application control, and credential theft protection
What is our primary use case?
Zscaler is a cloud proxy that scans and provides security for traffic to cloud-based applications and resources.
What is most valuable?
Zscaler is location-independent. Even if you switch to another country, users will have the same security posture. For example, if you are in one country and travel to India tomorrow, you will still have the same security posture as the rest of your team. You will also be able to access all your resources over the Internet as a team, regardless of location. There is no dependency on local firewalls at the site. Everything is in the cloud, so you get security wherever you go.
Zscaler provides several security features, including encryption, URL filtering, application control, and credential theft protection. They are also updating their DLP capabilities.
What needs improvement?
The reports can be made easier. The solution takes time to fetch reports in the Database section. Otherwise, the reporting module itself is well-designed.
For how long have I used the solution?
I have been using Zscaler SASE for two and a half years.
What do I think about the stability of the solution?
Zscaler is very stable. The customers use web services that cause issues over the internet.
What do I think about the scalability of the solution?
Zscaler is highly scalable. Zscaler is a cloud-based service, so it takes care of all the data center and hardware infrastructure. Even if you only have one license, you will still have access to all of Zscaler's security features and performance capabilities. Around 2Lakh users are in Nestle, and all are using Zscaler.
We work with enterprise-level customers.
How are customer service and support?
The customer support is good.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
I have experience with Prisma Access. In terms of scalability and tech support, Zscaler is better. However, Prisma is better in other parameters because they have more experience in the firewall industry and are the leader in firewall technology. We at Nestle are forwarding most of our traffic to Zscaler for scalability. We are using Prisma for some essential functions.
How was the initial setup?
The initial setup is easy. You have to plan very carefully how you are going to use Zscaler. Planning is critical, but implementation is achievable. You need to purchase cloud or host services and synchronize your user database to the rescheduler. Then, you just need to use the application to create a folder application on the system, and you are good to go.
Zscaler deployment time depends on the number of users and the policies to be deployed. A very simple setup can take around two to three weeks, while a very complex setup with multiple components can take months to implement.
What other advice do I have?
We are the service providers of Nestle, which is a user of Zscaler.
New functionality is always being added to Zscaler's products, but there are some features that we cannot have in the cloud-based platform. For example, Pulse QoS and VPN are still available as standalone products. However, Zscaler offers a variety of products that can meet these needs, such as ZIA, ZPA, and ZDA.
Maintaining Zscaler is easy. It has a well-designed admin portal and policy control. At least 20-30 people are required to manage the Zscaler product with a worldwide presence, depending on the setup. For example, Nestle requires 1-2 people to manage their Zscaler deployment.
I recommend the Zscaler solution. If I get an opportunity to use it in an environment where the users are mostly roaming users and the entire network stack is in the cloud, I will recommend they use Zscaler products. It's a great product.
Overall, I rate the solution a ten out of ten.
Which deployment model are you using for this solution?

IT Security & Operations Manager at a wholesaler/distributor with 5,001-10,000 employees
Filters well, with good whitelisting/blacklisting capabilities and installs easily on endpoints
Pros and Cons
- "Overall, the solution does a pretty good job at web filtering."
- "It needs to offer SSO, single sign-on, and items of that nature."
What is our primary use case?
The tool is a proxy service that provides inspection of URL filtering for internet access. We have probably 20 or 30 different vendors that we work with in regards to carriers. These are all providers that we use that work in conjunction with that platform. It's an agent that's installed on all of our endpoints. We whitelist and blacklist and we allow certain websites, et cetera, using this product.
What is most valuable?
Overall, the solution does a pretty good job at web filtering.
The solution does a good job of allowing us to choose what to whitelist and blacklist.
The agent easily installs on the endpoints.
What needs improvement?
The solution needs to offer better scalability.
The product needs SAML integration. That's something they should work to add in future releases.
It needs to offer SSO, single sign-on, and items of that nature.
The product needs greater zero-trust. They need to focus more on zero-trust relationships.
For how long have I used the solution?
I have been using the solution for about three and a half years at this point. It's been a while.
What do I think about the scalability of the solution?
The scalability is a weak point right now. Its scaling capabilities are lacking, and we'd like to see that improve in the future.
How was the initial setup?
The solution is basically an agent that is installed on endpoints in order to provide security. It's not overly complicated.
What other advice do I have?
We are not using the latest version of the solution. Currently, for example, we are one version back on that, as we don't typically do the most current version.
I'd rate the solution at a nine out of ten. We've, for the most part, been quite happy with its capabilities and the level of security it provides to us.
Which deployment model are you using for this solution?

Pros and Cons
- "As a cloud-based service, it is very easily implemented."
- "Price-wise, it is a costly product and it should be reduced."
What is our primary use case?
We are resellers and we have multiple vendors for multiple technologies.
We work with Zscaler for their proxy server.
Zscaler proxy server has two uses. It is not just application control, it is for the company users to access company data from the outside, or for the company users from inside the company to access the internet.
It's a completely SaaS-based application.
What is most valuable?
As a cloud-based service, it is very easily implemented. This is one of the biggest advantages to choosing it.
For how long have I used the solution?

What do I think about the stability of the solution?
This is a very stable product and we plan to continue providing it to our clients.
What do I think about the scalability of the solution?
As a completely cloud-based application, it is easy to scale. You can simply increase the number of users. We have between 30 and 40 customers who are using it.
How are customer service and technical support?
The technical support is very prompt and very good.
How was the initial setup?
It is straightforward to deploy. The length of time required for deployment depends on the number of users, but the average is within a week.
As long as you have some guidance or an understanding of the Zscaler platform, that should be enough to complete the initial setup.
What's my experience with pricing, setup cost, and licensing?
Price-wise, it is a costly product and it should be reduced.
It is an auto-renewal subscription service. It is renewed annually.
What other advice do I have?
This is a product that I recommend for anybody who wants a scalable, cloud-based solution.
Overall, this is a very good product. They release new features every year and they are automatically added to the platform. My only complaint is that the price is high.
I would rate this solution a nine out of ten.
