It's easy to roll out, and their understanding of our business made it seamless
One aspect we value about iboss is its simplicity. Their customer service is brilliant, and they are super responsive and knowledgeable. It's easy to roll out, and their understanding of our business made it seamless. 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. The user interface is highly intuitive. Our IT team picked it up with minimal training. It's arranged so that it's easy to find where things are. Another advantage is the single pane of glass console, which gives you visibility into what's happening. We're not fully there yet because we haven't implemented zero trust, but we're excited about the possibilities from the demos we've seen. We launched a POC of iboss' ChatGPT Risk Protection feature two weeks ago. AI is a great tool, but you need to be careful what you put into it. My biggest fear is employees inputting sensitive corporate information or customer PII data into one of these chatbots. I was impressed by our trial of the feature. It's exactly what we wanted. Now, when a user goes to ChatGPT, there's a banner warning them not to share information, and we can block conversations containing customer data like bank details and email addresses. I don't want to stop people from using it, but we need visibility. We've only tried it on a test group of 15 people. You can configure it to look for specific keywords or integrate it with your DLP policy if you have that configured

Makes us part of a bigger security ecosystem with updates taken care of for us, but pricing and support need work
There are definitely a number of things that could be improved. One of them is geographic coverage. China is still an issue because the solution does not operate there properly due to government regulations. I believe Palo Alto is trying pretty hard to get into partnerships with Alibaba and other cloud providers, but they do not have the same compelling offering in China that they have in the rest of the world. Businesses that are operating within China have to be very sure to evaluate the solution before making a buying decision. It is not an issue with Palo Alto, rather it is predominantly the result of government rules, but it's something that Palo Alto needs to work on. There is also room for improvement when it comes to latency in a couple of regions, including India and South America. They might have to increase their presence in those locations and come up with more modern cloud architectures. The third area is that, while Palo Alto has understood the essence of building capabilities around cloud technology and have come up with a CASB offering, that is a very new product. There are other companies that have better offerings for understanding cloud applications and have more graceful controls. That's something that Palo Alto needs to work on.

Helps maintain a consistent posture of internet security while getting rid of VPN and hovering into zero trust
There could be a better way for the tool to categorize the traffic. For example, the tool does exceptions and everything overall. If I want to give guest access or provide access to guest users or any other internet access and if it does not go through the SSL inspection because, in our company, we can't have the root certificate on a device that we don't manage, which can be called out as an exception or an exclusion, but that doesn't provide a proper reflection of the picture of what is happening in the environment. There are granularities bringing it down. The tool I used or still have is Zscaler Cloud Connector to protect the cloud environment, which can have a bit more user-friendly installation and setup, and it would help a lot. The deployment process of Zscaler Cloud Connector needs to be more user-friendly. Improvements are required in the exception category. For example, suppose I report on a monthly basis what the breaches and traffic violating the SSL inspection area are coming from. In that case, I may find that half of them may be coming through some guest network, meaning the tool doesn't differentiate between the guest or normal networks or the corporate networks. Having options to differentiate different networks would be ideal so that it can show a true picture of things to users, as half of the things in the tool are not in our control and are not of our concern.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The solution has massively improved our security posture, giving us full visibility into what our staff does online."
"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"Our primary use case for this product is DLP,"
"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."
"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."
"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."
"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."
"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."
"The always-on feature is fantastic for the users. They don't have to think about it. When they go to a coffee shop to do work, there's no need to remember to toggle the VPN on. We'll protect them. URL filtering is the same at home as it is in the office."
"The most valuable features of the solution are in the areas of the secure remote access it provides while also being user-friendly."
"Prisma Access by Palo Alto Networks is a seamless solution."
"This solution provides a DLP on the cloud and very few people have a scanning device for data at rest."
"Prisma helped us build a moat around our production systems. It's now impossible to log into our production from a non-MDM laptop. Prisma Access provides decent security overall."
"The features I find most valuable is WildFire, user integration, and the basic technology features."
"It is easy to use, easy to integrate, and is stable. It's scalable as well."
"It supports auto-scaling for mobile users. It auto-scales depending on the mobile user traffic. For example, if 1,000 people are working from home today, and tomorrow, the number increases to 2,000, it is not going to be an issue."
"Zscaler Internet Access protects using data loss prevention. If you have a CASB exposing your cloud out into the network, then Zscaler Internet Access will go ahead and control that unknown cloud application in the CASB, protecting it. There is also data detection with exact data match. This improves the data coming into your cloud so you are protecting it."
"The most valuable feature is bandwidth control."
"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."
"The most valuable feature of Zscaler Internet Access is that it is a consolidated solution, it comes with many features, such as DLP."
"One feature that is valuable to me from an implementation point of view is that it's very easy to implement."
"Zscaler excels in security protection and the cloud is always up-to-date. It does not matter if you are a small or big organisation, you will receive the same security quality."
"It is easy to set up the 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

"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"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."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"Its pricing could be better."
"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."
"Fold that in with the risk intelligence they're getting from all of the different subscriptions they are a part of. Now, these security companies subscribe to things like emerging threats, databases, etc. You can fold all this intelligence to decide what's happening on an endpoint. I would love to see them start moving into that space. That would compete directly with Microsoft. Maybe that's why they haven't. Having that ability native within the solution would be great. The other area in which I would love to see improvement is more detailed descriptions of why they block websites."
"The reporting feature needs improvement."
"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."
"We are using the SaaS offering. We use our applications for microservices. We use Twistlock to scan containers, and it displays these results in Prisma, which is a good feature because we can see vulnerabilities with respect to these containers. We can see everything in a very detailed manner. However, when you have different environments for a single application, such as DEV, QA, PROD, and TEST, all these environments run multiple containers, which can lead to a very high number of containers. In such a scenario, it shows you the alerts for all those containers that have vulnerabilities. If you show the results of all the containers that share the same image, it is not going to add any value. Therefore, they should narrow down the alerts based on a container. It should show information for a single container. Otherwise, the person who is looking at the results gets the impression that he has to fix all these issues. This is something that they can improve."
"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."
"I haven't seen any SD-WAN configuration capability. If Prisma Access would support SD-WAN, that would help... SD-WAN devices should be able to reach Prisma Access, and Palo Alto should support different, vendor-specific devices, not just Palo Alto devices, for SD-WAN configuration."
"The cloud setup is straightforward, and the onboarding process is much better, but the on-premises initial setup is slightly complex."
"The user interface could be better. They need to work a little bit on the console. It is similar to their firewalls but not exactly. They need to clean it up a bit."
"There is some particular traffic that the security team wants to filter out and apply their own policies and they cannot."
"The product's current price is an area of shortcoming where improvements are required."
"I would like to see more training and video documentation."
"In every cloud service in the world, you have multiple upstream internet providers to create diversity so that if one of your providers fails, your network just continues. In South Africa, there is only one upstream provider, and that's not right. That that's a problem."
"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."
"One feature I am missing is the ability to connect automatically to internal monitoring systems."
"​When you have appliances, SSL inspection is always a headache due to poor performance and/or lack of ciphers implemented. ​"
"They should enhance the audit reporting feature."
"One thing that they could improve is the ability to import rules from other platforms."
"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 not expensive, and it is also not cheap. iboss is priced right in the sweet spot for the number of features it offers."
"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."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"The overall pricing for iboss is very competitive and transparent."
"It is probably in line with other solutions, but I do not deal with the financial side."
"It is expensive compared to one of its competitors."
"As compared to other solutions, Prisma Access is much cheaper. It is probably 30% to 40% cheaper than other solutions, but I do not know the exact cost."
"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."
"It is pretty expensive. We have to balance the cost of some features. They need to work on some of the services and products, price-wise."
"The price has been good for the ROI during these difficult times for the cruise industry. There are no hidden costs; what the product offers is what you get."
"This is not an expensive product and everything is included with one license."
"It's pricey, it's not cheap. But you get what you pay for."
"The solution is expensive."
"The pricing is very friendly. It's not confusing to figure out your workload and how much you'd be paying for the solution."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"The price of Zscaler Internet Access should improve, it is expensive."
"The pricing for Zscaler Internet Access could be made cheaper."
"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."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"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."
"It is costlier than other solutions."
"The solution is a little bit expensive. On a scale of one to five, I would rate it as a three."
