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

Helps us manage traffic-related issues and streamlines access management for the network
Appgate SDP has significantly streamlined our access management, providing a notably efficient solution compared to traditional VPNs. The simplicity of the SDP platform is a standout feature; instead of navigating through intricate details, users can seamlessly connect to the company's network or switch to the internet with minimal effort, unlike VPNs which often involve waiting for connection handling and unblocking. Recognizing the robustness of SDP, we made strategic decisions to minimize reliance on VPNs, reserving only two for administrative purposes. In a scenario where Appgate SDP significantly improved our network security posture, the platform played a crucial role in fortifying defenses against major threats. The encryption algorithms utilized by SDP provide a high level of security to our network architecture. Compared to Cisco, SDP proves to be most critical in protecting resources with the help of role-based policies. It only provides selective access to the application. The dynamic policy engine significantly enhances our access control mechanisms. It has single sign-on and multifactor authentication features. It makes processes faster and easier. It has helped our IT team to manage the workload with ease. It gives an intelligent solution whenever they face traffic-related problems. I rate it a nine out of ten.

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

"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."
"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"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 pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."
"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."
"iboss is among the few products providing inline filtering where no application is needed on the device."
"Granular setup, which was able to set different levels of filters using the OUs in the AD."
"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."
"It is pretty stable."
"One of the most important features is stopping lateral movement across our network."
"The flexibility of the tool is valuable. It is very robust. It has a very robust configuration capability."
"The interface is really friendly. It's simple to understand."
"It is a scalable solution...The support answers your questions very fast."
"The simplicity of the SDP platform is a standout feature; instead of navigating through intricate details, users can seamlessly connect to the company's network or switch to the internet with minimal effort."
"I like the web filtering capabilities."
"It is a stable solution."
"The scalability of the solution is great."
"The product provides a seamless user experience."
"I find all Zscaler Private Access features valuable because each replaces flawed technologies, such as EPAs being replacements for VPN and PR as a replacement for PAM, so I can't mention only one valuable feature. Overall, Zscaler Private Access is a good solution."
"Its impressive scalability allows the combination of multiple dictionaries and using them as one engine, resulting in narrower data loss gaps."
"We don't need to connect anymore. It is automatically connected when you log on in Windows."
"The agent's versatility is notable, used for digital experience monitoring to collect valuable endpoint metrics for troubleshooting."
 

Cons

"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."
"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."
"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."
"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."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"Iboss is growing so fast that it is often hard for them to keep up with the challenges."
"Sometimes, obviously, there are bugs."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"One thing that kind of sticks out to me is the ability to do a proper non-split tunnel. VPN tunnel-wise, it is not really a true unsplit tunnel, but I think that's just because of the way it's designed. A split VPN basically allows your system to talk to other systems without being forced down the tunnel. A VPN running in a non-split tunnel mode forces all the traffic down the tunnel to wherever you're VPNing to. It forces the traffic down so that the traffic is subject to the firewall and rules that you have in your corporate environment and such. It helps to prevent remote malicious folks that may be talking directly to that box from piggybacking into the corporate environment through it. They do it partially, but it would be nice to see more of an enterprise-level solution there."
"They could provide a single-box solution to manage tools for 4000 users. Additionally, they could add extra features to enhance remote micro connection."
"It would be better to connect to an application portal from any device. Documentation and support could be better."
"The user interface should be improved as it is not very easy to work with the updates."
"One limitation is that it's harder to provide access to multiple applications in the company with Appgate, but that's probably because of poor management."
"On the cloud, when you make some changes, it may be difficult."
"While Zscaler supports client-initiated connections, it does not support server-initiated connections. This is a feature that Zscaler may consider adding in the future."
"User management can be improved."
"There is some issue while accessing the portal. It takes too long."
"The stability could be improved."
"We have issues with the tool's maintenance and networking. It should be able to work in offline mode as well."
"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."
"More on-prem infrastructure is required when Zscaler Private Access is to be implemented as a single point of entry."
"The tool must provide IP-blocking features."
 

Pricing and Cost Advice

"It is expensive compared to one of its competitors."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"It is probably in line with other solutions, but I do not deal with the financial side."
"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."
"The overall pricing for iboss is very competitive and transparent."
"It is a pretty expensive tool. It is maybe about $20,000 per year for a hundred users or so."
"The pricing is according to the market price. It is not a very cheap solution. They have some very aggressive promotions to sell the product in the market."
"We pay $100 per user per month. One license for the site is around $17."
"Zscaler Private Access can be an expensive solution, depending on the license type you will purchase."
"The licensing model for Zscaler Cloud DLP allows you to only buy what you need. You don't need to buy it as a whole, so it's good."
"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 is expensive."
"In terms of market positioning, I would describe Zscaler Private Access as offering optimal pricing. Based on our experience, Cato Networks tends to be slightly more expensive."
"It's expensive currently. But when purchasing for a large number of users, there's room to negotiate. It's really up to the procurement team."
"Zscaler CASB is an expensive solution."
"Zscaler Cloud DLP is moderately priced. We pay around 2 million rupees per year."
