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

"Technical support is pretty sharp and very responsive."
"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."
"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."
"It was a very easy product to install. It can be deployed very fast."
"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."
"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."
"Content filtering is the most useful feature of iboss."
"The users can securely access any cloud data centers or cloud platforms. In terms of the features, it has all the features that Palo Alto Next-Generation Firewall has. It is also very stable and scalable."
"Prisma SaaS is very easy to use; it's common sense — it's the best-in-class."
"We have an application called ADEM that helps us troubleshoot network-related issues. It helps us to isolate an issue whether it is on the ISP level, endpoint level, or system access level."
"To quarantine and clean a malware file provides a lot of security."
"The solution has all its capabilities in a single cloud delivery platform which is great and it provides overall good protection."
"This solution provides a DLP on the cloud and very few people have a scanning device for data at rest."
"The most valuable feature is the ability to change the gateway. For example, if there's a problem with a specific region or vendor, we can make modifications. The solution is scalable, and there are different gateways that can be created depending on the demand."
"It is easy to use, easy to integrate, and is stable. It's scalable as well."
"​After a proper implementation, the maintenance is very low.​"
"All internet access flows through the Zscaler proxy, regardless of whether people are in office or remote. I have greater control site access and I minimize the number of compromises that we experience to almost none."
"We enjoy all of the proxy capabilities and the capability to integrate into the SIEM/SOC solution."
"One on the main benefits is protection all time from anywhere."
"The most valuable features I found in Zscaler Internet Access are the restriction of users for a particular URL, the security feature related to stopping DDoS, and the VPN."
"The most valuable feature is the ability to drop packets."
"The security is excellent."
"The URL filtering has been the most valuable feature."
 

Cons

"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."
"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."
"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."
"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"Iboss is growing so fast that it is often hard for them to keep up with the challenges."
"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 solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."
"From any improvement perspective, the product's compatibility issues with Linux need to be resolved."
"The BGP filtering options on Prisma Access should be improved."
"We would like to see improvements in the licensing; currently, Palo Alto provides 500 to 1000 licenses for users, and we want to see 1500 to 2000 licenses for one version."
"I would like the solution to support a different type of authentication. We can't configure a secondary method for our portal."
"The tools' scalability is subject to some limitations when done on-premise due to the need for additional licenses. However, in other scenarios, increasing scalability involves expanding infrastructure to accommodate more third-party VPN access. It is scalable as long as you pay the money. Also, it needs to improve security."
"There can be some latency issues with the solution that should be improved."
"The solution’s stability could be improved."
"When we deploy firewall rules via Panorama, we find it's a little bit slow. We have a global environment and might have 100 gateways or VPNs in the cloud. When we deploy something, it tries to deploy it one-by-one, and that can be slow."
"The solution can be improved by advancing some of the newer technologies such as the DLP feature, and adding email security."
"The OS capabilities and WSL support could be improved."
"Zscaler Internet Access can improve by adding traffic filtering based on the DNS."
"The solution's pricing is on the higher side. It would be better if it could be lower."
"One feature I am missing is the ability to connect automatically to internal monitoring systems."
"I would like to see more training and video documentation."
"The interface for administration could be better. They should upgrade the management portal."
"If they can also integrate with the multi-factor authentication to prompt users to do another, second-factor authentication, that would be ideal."
 

Pricing and Cost Advice

"It is probably in line with other solutions, but I do not deal with the financial side."
"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."

"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."
