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

Enables seamless policy management and supports secure remote work
Our primary use case for Prisma Access by Palo Alto Networks is to control the internet and serve as an internet proxy. Additionally, we use it for secure remote work One of the most valuable features of Prisma Access by Palo Alto Networks is the ability to manage on-premise firewalls. We can…

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

"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"Content filtering is the most useful feature of iboss."
"From a use-case scenario, what I like the most is the plug-in. I like the fact that we can do the filtering of these devices offsite independent of the network they are connected to, and we do not have to have traffic coming back inside our network."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."
"Our primary use case for this product is DLP,"
"Technical support is pretty sharp and very responsive."
"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."
"You have the ability to create your own expressions for your data. Palo Alto understands that DLP is not the same for all consumers. You might have a particular need to fulfill, and they give you the opportunity to create a custom expression to match the specific format that you have. For a confidential file property that you have in your files, you can add a metadata field. It gives you that opportunity to create that."
"To quarantine and clean a malware file provides a lot of security."
"Prisma Access by Palo Alto Networks makes our life easier because the firewall solution we had before was totally outdated and performing poorly. This solution has completely transformed our operations."
"The product's initial setup phase is simple."
"Prisma Access gives us security from a single point. It controls mobile users and determines how secure their networks will be, including from where they will get internet access. We can optimize things and add security profiles centrally."
"The solution also provides traffic analysis, threat prevention, URL filtering, and segmentation. That combination is important because it enhances the protection and makes the traffic more secure. It also keeps things more up-to-date, enabling us to deal with more of the current threats."
"Monitoring is the most valuable feature because we can easily monitor all kinds of stuff coming over the network. We can check the dashboard and work accordingly."
"The solution improved the consistency of our security controls and the BCP. There has been a 20 percent reduction in TCO. Prisma Access also enabled us to deliver better applications by centralizing security management."
"Zscaler Web Security protects our users in remote locations from internet threats - even if they are not connected to our network."
"The solution offers a distributed organization to master and to control all of the endpoints."
"One feature that is valuable to me from an implementation point of view is that it's very easy to implement."
"In terms of management and visibility, there is a single panel where you can configure the policies for your entire organisation worldwide."
"The solution is stable and reliable."
"The most valuable features of Zscaler Internet Access are it's on the cloud, high network performance, and the interception of users is very easy."
"There is no lag in service when accessing the internet."
"Zscaler Internet Access is less expensive than competitors like Palo Alto, offering a premium service justified by security enhancements and cost-effective scalability."
 

Cons

"The dashboards for local use could be better."
"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."
"Their on-premise hardware's network interface is capped at one gigabit, which is sort of a problem. If you stand a filter up where all traffic flows through that, according to them, in order to go above a gigabit, you have to have multiple devices, which in today's IT seems a little bit silly. They could easily put in an SFP port into their device that could accommodate 10 gigs or at least offer a box."
"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."
"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"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."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"The cloud setup is straightforward, and the onboarding process is much better, but the on-premises initial setup is slightly complex."
"One area for improvement is for them to stay on top of keeping their CVEs on their platform up to date."
"It wasn't so satisfying to work with it. There is room for improvement in the policy management. It is difficult to cover the entire scenery through Palo Alto products."
"The product's price is an area of concern where improvements are required. The solution's price should be lowered."
"The frequency of updates could be reduced."
"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."
"Prisma's integration between operational technology and IT should be more seamless. Right now, it requires additional setup and maintenance."
"Prisma would be a stronger solution if it could aggregate resources by project or by application. So say we have an application we've developed in AWS and five applications we've developed in Azure. The platform will group it according to those applications, but it's based on the tags we use in Azure, which means I have to rely on development teams to tag resources properly."
"One feature I am missing is the ability to connect automatically to internal monitoring systems."
"The interface for administration could be better. They should upgrade the management portal."
"I would like to see the ability to choose a pool of IPs for my company, set up rules based on them, and know that those IPs are not used by other companies."
"The reporting functionality could be a bit easier to use. There is a reporting function, but it's quite hard to do any good reporting, from a user-management perspective. For example, if a department manager wants to know how his department is using the web, there is a way to get the data, but it's quite cumbersome to get it and show it well. And that's true for comparing between departments."
"In terms of user experience, it could be better."
"They could provide more time for the onboarding the training of an IT person."
"Zscaler Internet Access needs to integrate more ISPs. It is good to have more than three ISPs."
"Another thing that I would like to see is if Zscaler could have a separate product for direct access. I looked at a private access solution, but I understand there's a separate product that isn't integrated with this."
 

Pricing and Cost Advice

"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."
"It is expensive compared to one of its competitors."
"It is probably in line with other solutions, but I do not deal with the financial side."
"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."
"The overall pricing for iboss is very competitive and transparent."
"The pricing for this solution is on the higher end."
"It is not cheap. It is expensive. The good thing is that you are able to pay for what you need, but overall, it is not cheap. The pricing is not based on packages. You pay based on the features. If you want DLP, you only pay for DLP. They are very flexible. It is not cheap, but the licensing is flexible. There are no additional costs in addition to the standard licensing fees."
"The pricing is very friendly. It's not confusing to figure out your workload and how much you'd be paying for the solution."
"We have to pay additional costs for maintenance and support services."
"Prisma Access is a little bit expensive."
"I'm still comparing, but the solution is quite expensive."
"It's pricey, it's not cheap. But you get what you pay for."
"There's no reason not to buy the enterprise version that gives you unlimited PoPs, but you must understand the limitations you impose on yourself if you do that. If you go crazy, that allowlist will be too big for Kubernetes clusters."
"The price of Zscaler Internet Access should improve, it is expensive."
"If we need any extra features, the price will increase."
"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."
"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."
"Licenses are available on a per-host basis. Some features like sandboxing require an additional fee, but most standard features are included in the license."
"The price is competitive. It's not cheap and it's not expensive."
