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.

User access is simplified and secured through central core functionalities
The simplicity and logical structure of Zscaler make it easy to use and administer. It allows grouping, enabling en masse access conveniently. Unlike the BlueCoat proxy, which was more prescriptive and individual-focused, Zscaler offers group access. Additionally, Zscaler's modern tools enhance the network architecture by passing everything through a central core of security, ensuring everything is secure before accessing the internet.

Quotes from Members

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

Pros

"Content filtering is the most useful feature of iboss."
"Its initial setup was straightforward."
"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."
"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."
"The security aspect of the solution, particularly the malware behind it, is excellent. That's something that really helped us out. It's not just a simple proxy that just blocks the insights of potential threats that come on behind it. They do malware detection and that helps us a lot."
"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."
"iboss is among the few products providing inline filtering where no application is needed on the device."
"From stability and availability standpoints, it is pretty good."
"The quarantine feature is the solution's most valuable aspect."
"The product is stable."
"The tool's most valuable feature is reporting. It helps us understand what's going on in our environment."
"The scalability is amazing. Whenever we need to upgrade the users, it increases immediately."
"Zscaler Private Access (ZPA) is more secure than these particular VPN solutions."
"The features I appreciate the most about Zscaler Private Access (ZPA) are that it is very easy to use, and we have Terraform for it, which makes it even easier and very straightforward."
"The best advantage of the product is that it is always on as a VPN, which gives us much more functionality."
"Zscaler Private Access (ZPA) does an excellent job offering secure remote access to internal applications for our distributed workforce because it provides a granular way to grant access for specific people with specific applications."
"Zscaler Private Access (ZPA) is much more secure than VPN because users are only allowed to access specific applications rather than the whole network."
"Zscaler Private Access helps by resolving network choke issues, allowing application access from public networks without needing to integrate with internal networks."
"Overall, I would rate it a nine out of ten."
 

Cons

"Iboss is growing so fast that it is often hard for them to keep up with the challenges."
"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."
"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 area I would like to see improvement in is the ability with in the reporter to navigate directly to the content the user is traversing. It is kind of there, but it's not perfect. Quite frequently, I receive links that lead me to pages with error messages."
"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."
"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."
"The reporting feature needs improvement."
"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."
"Proofpoint Cloud App Security Broker should be cheaper."
"They are priced significantly higher and less cost-effective than alternative options."
"The solution is not scalable; we deploy it in a high-availability environment, but it's not automated."
"Customer service and support are rated seven or eight out of ten, needing improvement in quality and response time."
"The current pain points we sometimes experience relate to the additional security applications we have on the laptops, and sometimes I don't know if I didn't get any notification from the application because it's an agent problem or something security-wise blocking this."
"The lack of control over the 700+ external IPs through which traffic exits Zscaler is problematic."
"One area for improvement is setting posture profiles for vendor machines."
"There are some bugs in the solution."
"The price is a concern as it increases every year and becomes more expensive, driving customers and other vendors to look for alternatives."
"Sometimes connection errors occur when users are unable to connect to the particular cloud."
 

Pricing and Cost Advice

"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 expensive compared to one of its competitors."
"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."
"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 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."
