Enhances web security with a single pane of glass and flexible deployment
I don't see any need for improvement; one of the really good things about iboss as a company is that they listen to customer feedback. I have suggested enhancements, and they are responsive, making changes for the better, and they do a lot of testing. To improve iboss, although we haven't used it, we considered the VPN solution that comes with the highest tier licensing, which includes DLP and various other add-ons. We prefer using another product which automatically logs you back onto your network when turning on your PC. With iboss, the connection is manual, which doesn't meet our needs. Additionally, sizing can be tricky because, although the initial recommendations may seem adequate, actual usage may require more gateways than anticipated.

Have supported client adoption of security solutions but need more control over infrastructure
It's a working solution. It's not the easiest, but no DLP solution is easy. With Netskope, the whole infrastructure is proprietary. Prisma Access by Palo Alto Networks is using a service in AWS, and it's not totally a proprietary infrastructure. Sometimes a third-party outage could impact the whole operability. I'm not certain if the vendor is moving towards sovereignty of infrastructure at this moment, but from what I saw in the past, there was this reliance on third parties for the infrastructure: AWS, GCP, Oracle, and others. This is one point of attention for me. I would prefer more proprietary infrastructure.

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

"iboss is among the few products providing inline filtering where no application is needed on the device. It operates on the network side and is not device-based. This feature was one of the main reasons why we stayed with them for so long."
"The iboss system is highly reliable. The false positive rates are small compared to some other systems we've experienced through other partner agencies who use competing solutions."
"We were impressed by the solution's mental health function, which can detect if someone needs help. It scans what users are browsing and flags warning signs so we can check to see if they are okay. We've had to use it a couple of times."
"It was a very easy product to install. It can be deployed very fast."
"iboss has significantly lowered the number of security incidents. It is crazy how much it blocks and how much it is aware of the outside danger."
"iboss is among the few products providing inline filtering where no application is needed on the device."
"Valuable features: Within the filter: Controls (Web categories, applications, and Allow/Block list) and Network (local Subnets). Within the reporter: Logs (Event Log) and Reports."
"Our primary use case for this product is DLP,"
"Prisma integrates well with Cortex XDR and Cortex Data Lake. My company has been also using Prisma Access in-house for nearly a year, and it integrates seamlessly."
"Security is absolutely spot-on, really top-notch. It's the result of all the components that come together, such as the HIP [Host Information Profile] and components like Forcepoint, providing end-user content inspection, and antivirus. It incorporates DLP features and that's fantastic because Prisma Access makes sure that all of the essential prerequisites are in place before a user can log in or can be tunneled into."
"A feature I've found very helpful is run time security because most of the products on the market will look at security during the build time, and they don't really look at what happens once you're going into production."
"The solution has all its capabilities in a single cloud delivery platform which is great and it provides overall good protection."
"To quarantine and clean a malware file provides a lot of security."
"The scalability of the solution is excellent."
"The performance is good."
"Palo Alto Firewall is one of the best firewalls in the world."
"The solution offers a distributed organization to master and to control all of the endpoints."
"Zscaler offers a centralized DLP solution for web, endpoint, and email."
"For our needs, the cloud-native proxy architecture is a very good solution. We are moving away from on-prem appliances and moving more toward cloud-based solutions. Zscaler is a good fit for our strategy. This architecture helps with cyber threats because we inspect most of the traffic and we can see that a lot of threats are stopped directly in the secure web gateway."
"Zscaler Internet Access's roaming user feature is most valuable and is much better compared to other secure web gateways."
"The VPN is valuable, as the whole technology is very different from a traditional VPN."
"The most valuable features of Zscaler Internet Access include its capacity to scale, the security implementation capabilities, the ability to integrate public IPs related to clients so traffic presents on the internet as a client, and the facility to interoperate with SSEs while maintaining the same security mechanisms from on-premises to cloud environments."
"We enjoy all of the proxy capabilities and the capability to integrate into the SIEM/SOC solution."
"The best thing about Zscaler Internet Access is the website filtering. In the UAE it's quite an important feature because most of the malware comes through the SQL injection and through downloads from websites. Zscaler helps protect against that."
 

Cons

"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."
"Iboss is growing so fast that it is often hard for them to keep up with the challenges."
"Its pricing could be better."
"One thing I would like to see differently with their Zero Trust platform is that some of the AI aspects related to high-risk activities have more false positives."
"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."
"I am currently doing a PoC of the zero trust aspect of it. Compared to other similar solutions, it is hard to get around each feature. It takes a while to get used to it."
"SSL decryption: We had issues with learners using apps instead of using web browsers. This type of encryption is tough for any appliance in a BYOD environment."
"The reporting feature needs improvement. It doesn't give you the expected results. It is quite difficult to get the specific reports needed, and it is not as intuitive as the rest of the platform."
"Its integration with non-Palo Alto products can be improved. Currently, it is easy to integrate it with other Palo Alto products such as Cortex XDR. It integrates well with other Palo Alto products. A major part of our network is based on Palo Alto products, but for those companies that use multi-vendor products in their infrastructure, Palo Alto should optimize the integration of Prisma Access with the network devices from other vendors."
"There should be a dedicated portal or SASE-based solution. They're trying to add a plugin but it needs a dedicated portal because it is now an enterprise solution for multiple organizations. People should be able to directly log in to a dedicated page for Prisma Access, rather than going into a Panorama plugin, and always having to update the plugin."
"Better integration with the MDM solution would be useful."
"They could add more flexibility and improve product performance."
"Palo Alto needs to improve the GlobalProtect agent to work as a secure web gateway agent, not only as a VPN agent because some companies would want only a secure gateway. They wouldn't want a full VPN. So, Palo Alto has to make the VPN agent work as a secure web gateway agent for those customers who want only the secure web gateway solution."
"Sometimes, you have these notifications sent out about changes in App-IDs, modifications in App-IDs, or even the introduction of entirely new App-IDs to replace. Sometimes, the recommendations are followed, but even then, when the package is installed on the firewall, it gets messed up. I remember a particular one was with Tableau, and suddenly, people weren't able to use Tableau, which is an analytics tool for business."
"GlobalProtect can face challenges with latency, especially when remote workers connect to centralized locations."
"It's not very easy to use. Sometimes it's buggy and there are problems when doing updates. The user interface is okay, but some configuration items are difficult. I would like it to be less buggy and easier to configure, to better streamline the user experience."
"Zscaler should continue to make the user interface better. They should also improve the backup network and continue to expand it so that it can handle larger numbers of customers."
"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."
"Technical support could be better."
"There are a few features that are not compatible with the Azure cloud."
"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 admin console needs improvement as it loads slowly and sometimes takes two to five minutes to open."
"Zscaler should provide adjacent services, which would be complementary to their current offering that could to be more pragmatic for a customer. For example, if you take Akamai, you get multiple sets of services, all depending on the customer and the strategy and the complexity and the problems. In some areas, they are more varied in terms of coverage."
 

Pricing and Cost Advice

"It is expensive compared to one of its competitors."
"We had the cost of purchasing a new appliance along with the implementation and licensing costs. However, the following year, the cost of just licensing was similar to what was paid the previous year for a new appliance along with the implementation and licensing costs."
"The overall pricing for iboss is very competitive and transparent."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"It is not expensive, and it is also not cheap. iboss is priced right in the sweet spot for the number of features it offers."
"It is probably in line with other solutions, but I do not deal with the financial side."
"In terms of pricing, considering that it is a two or three years old solution, they should apply big discounts for the next two or three years. This approach will be better for them to capture the market."
"The pricing for this solution is on the higher end."
"The pricing can be difficult because it came to us with another agreement, but it can be negotiated. I highly recommend people to compare this product's performance and pricing against BetterCloud, because I feel BetterCloud is better than Prisma SaaS if they're starting from scratch."
"Prisma Access by Palo Alto Networks is an expensive solution, especially when compared to other solutions like Cisco. There are no additional charges apart from the standard licensing costs attached to the solution."
"Prisma is in the middle of the road. It's not the most expensive, but it's not the cheapest. There aren't any additional costs, to my knowledge. I know they have some extra modules, but we didn't use them."
"They price their products using credit modules."
"I'm still comparing, but the solution is quite expensive."
"The licensing model for this product is complicated and changes all the time, making it very hard for the user to comprehend the configuration."
"It is costlier than other solutions."
"We have found the solution to be expensive."
"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 tool is moderately priced."
"Price-wise, the tool is reasonable compared to the other products in the market but it is not a very low-priced tool. The solution does provide value for money."
"Our monthly fee is around R3000."
"Zscaler is transparent about its pricing model."
"The pricing is fair based on its competitive market."
