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

Stable product with essential document tracking features
In my organization, we worked with around ten to fifteen different technologies, including Bitglass, and CASB was not among our top priorities. While CASB might benefit some organizations, it was optional for our specific setup, considering the other security measures and technologies we had in place. I found no particularly valuable features regarding CASB resolutions. There are other tools available that can achieve the same functionalities and perform similar tasks. For example, I can accomplish tasks like encryption or secure data movement from our office to the internet using alternative services like Zero Trust solutions. Because of this, our organization considered removing it from our system due to its limited benefits compared to other products.

Cloud-based platform simplifies device and data center management
I find it to be good. The solution is cloud-based with the latest inspection engines, which I find to be amazing. We are less dependent on data centers and device management, which reduces our efforts significantly. It improves our device management, data center management, and updating devices. We need fewer engineers for this management, and it reduces time and efforts for data center management, device upgrades, and IT support.

Quotes from Members

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

Pros

"iboss is easy to use despite its complexity. Multiple engineers manage it, but it's significantly more straightforward to administer than traditional VPNs and web proxies."
"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."
"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."
"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"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."
"It was a very easy product to install. It can be deployed very fast."
"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."
"The console is cloud-based, which is something I really appreciate."
"The quarantine feature is the solution's most valuable aspect."
"The product is stable."
"From stability and availability standpoints, it is pretty good."
"The tool's most valuable feature is reporting. It helps us understand what's going on in our environment."
"I like its ease of use. It has a single pane of glass for the ZIA and ZPA pieces. It is very manageable. It is also very easy to deploy for secure access, and it gives half-decent coverage for visibility in terms of what the users use and what data is being proxied through the access gateway."
"This secure connection allows users to connect to the Zscaler VPN and access the resources on the office network, making it a highly valuable component of our system."
"The product provides a seamless user experience."
"The UI is easy to use."
"Sandboxing, DLP, and SSL inspection engine are the most valuable features of Zscaler SASE."
"Its impressive scalability allows the combination of multiple dictionaries and using them as one engine, resulting in narrower data loss gaps."
"The Live Logs are a cool feature. We can directly identify issues and divert user traffic."
"It has some good data security and WIP features, providing secure Internet access."
 

Cons

"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."
"Our iboss subscription access should be more secure with an OTP or VPN etc. It is easy to gain access if, for example, hackers obtain my username and password."
"The dashboards for local use could be better."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"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."
"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."
"The reporting feature needs improvement."
"Iboss is growing so fast that it is often hard for them to keep up with the challenges."
"They are priced significantly higher and less cost-effective than alternative options."
"Proofpoint Cloud App Security Broker should be cheaper."
"I think some of the hiccups that we had were with the number of domains that we had and how that had to be implemented in Proofpoint."
"The TLS encryption needs to be improved. It's not state of the art."
"I can't speak to any missing features."
"Occasionally, issues arise in the LogStack by a third party, particularly for government websites accessed by numerous users."
"Price-wise, it is a costly product and it should be reduced."
"The pricing for Private Access seems to be on the expensive side, and I believe they should consider making it more competitive with other solutions."
"The product is not reliable."
"In the next release, I would like to see RE2 Regex supported."
"The DX layer could be better if it had improved visibility."
"The solution's granularity should be improved because it has limited granular options to control, visible, allow, block, delay, and receive."
 

Pricing and Cost Advice

"The overall pricing for iboss is very competitive and transparent."
"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 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 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 tool's most valuable feature is reporting. It helps us understand what's going on in our environment."
"We had an enterprise contract with them for about 32,000 users at that point, which has now grown."
"Zscaler DLP solution is expensive, with a fixed pricing structure that is billed annually and monthly. There are no additional costs for licenses."
"The product is a little more expensive than other tools."
"Zscaler SASE software is quite expensive compared to other solutions"
"In the long run, cloud services are not inherently costly."
"Pricing for Zscaler Private Access is moderate. It's acceptable, though I can't give you the exact price currently. It's not too expensive, and on a scale of one to five, I would rate it a four out of five in terms of pricing."
"The solution has increased prices this year."
"The cost is expensive. It depends on the number of users."
"It's an affordable solution"
