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

Centralized authentication simplifies logins and saves time
There aren't any new features or functionalities in Cisco Duo that my company has started using recently; we use it primarily for the authentication portion. There are other features we can use, yet we haven't turned those options on yet, so that's more a matter of time than anything. We have many different vendors and types of devices that we require MFA for login. That said, Duo helps bring all of those accounts into one system, in conjunction with ISE, you have one username, one password, and you access all the devices instead of having every device have its own credentials. It lowers the number of passwords you need to have. Cisco Duo is on the right track for improvement. A lot of their devices already integrate with it now. They keep adding features for more devices that interact natively with it, instead of having to have a third-party server to reach out to Duo. I would rate Cisco Duo overall about an eight out of ten; it's a strong product.

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

"Granular setup, which was able to set different levels of filters using the OUs in the AD."
"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."
"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."
"The solution has massively improved our security posture, giving us full visibility into what our staff does online."
"iboss is among the few products providing inline filtering where no application is needed on the device."
"Content filtering is the most useful feature of iboss."
"It was a very easy product to install. It can be deployed very fast."
"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."
"All features of the solution are effective, particularly those involved in identifying vulnerabilities and updates."
"It is a good solution for hybrid environments and VPN."
"Cisco Duo is quick to deploy and easy to start."
"Cisco Duo is rock solid in terms of stability and reliability."
"We were considering purchasing other products, like AMP for Endpoints, and it was not properly integrated with the firewall function. It might be better now with SecureX."
"Multifactor authentication and secure two-factor authentication are the most valuable features. It's been around for a while, but now it's becoming an enforced behavior as opposed to something that you used to do as optional."
"The feature of Cisco Duo that I appreciate most is the push notifications. They are great."
"For me, the biggest return on investment when using Cisco Duo is my time."
"The most valuable feature is its ability to establish connectivity for remote users and remote endpoints. It offers a high level of granularity compared to typical VPNs, which also encapsulate a lot of I/O."
"What I find most valuable in Zscaler Private Access is that it's a VPN. Its connectivity as a VPN is its most valuable feature."
"It has been helpful in maintaining our infrastructure. The granular level control it offers allows us to set application policies per application for each user."
"Its impressive scalability allows the combination of multiple dictionaries and using them as one engine, resulting in narrower data loss gaps."
"The most valuable feature of Zscaler Private Access is we do not have to connect to a VPN, it is seamless. It is more convenient for us because we use one agent to cover the internet and VPN access."
"The UI is easy to use."
"Has a good zero trust feature."
"Yes, it is very stable. I have never seen it go down, not once."
 

Cons

"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."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"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."
"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."
"The dashboards for local use could be better."
"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."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"Sometimes, obviously, there are bugs."
"The dashboard needs to be improved."
"We use Yubikey for pushing it to the phones. Yubikeys can get expensive because people tend to lose those for some reason. Fifty dollars a device is pretty high."
"The pain point for us at one point was the Duo Authentication Proxy since we're on-premises and not in the cloud. We had to have a proxy machine that's in our DMZ to talk to Duo for us. The configuration of that was a little complicated."
"It is easy to use when logging in, but at times, there's a delay in getting the pop-up on a phone, requiring users to occasionally retry authentication depending on backend services."
"For the back-end, there could be a few more security features applied."
"The product price needs improvement."
"An enhancement they might make is if they can log it to Splunk since they're big into Splunk. Instead of me having to go into that portal to look at things when someone is trying to log in and they forgot their password, I can look in and tell them they forgot their password or didn't respond to the prompt. That would be an improvement."
"I wish that the support would be a little bit more prompt and a little bit more flexible because there are certain things that they will do and certain things they won't do."
"Sometimes applications crash on some machines, and we’d like Zscaler to give us some information as to why that may have happened. We’d like more detailed reports."
"The only issue with Zscaler Cloud DLP is that it only gives you DLP protection from web traffic, which is flowing out, while a full-blown DLP solution such as Forcepoint or Symantec gives you DLP coverage for multiple channels. Zscaler Cloud DLP doesn't give you coverage for email, fax, and USB channels, and this is the only challenge or room for improvement in the solution. It's just an extension on top of what you're buying on the proxy, so it's just an added layer, and it doesn't cover DLP on a very broad level. I'm unsure if Zcaler is in the business of competing with a full-blown DLP solution, and if there's a plan to expand the features of Zscaler Cloud DLP beyond the web channel because you'll have to deploy a full-blown agent for it. I'm unsure if this is on the cards because the solution is just an added layer that you get with your proxy. I've asked the Zcaler team whether there's a plan to go full DLP in the future, but I didn't get a positive response. There isn't any feature I'd like added to Zscaler Cloud DLP currently, because anything you could think of that should be in cloud or SaaS solutions is already there, except for machine learning, as it's the only functionality that seems to be lacking in the solution. Machine learning is an additional policy available in other DLP solutions in the market, but my team didn't find it in Zscaler Cloud DLP."
"We'd like to have two-factor authentication that is quite simple."
"To enhance their offering, it is advisable for them to focus on strengthening the foundation of their architecture. Additionally, they should consider integrating a broader range of services that go beyond what managed service providers typically offer independently."
"The solution needs to improve a lot of aspects."
"Having a Zscaler-specific device could streamline this process and provide a more consistent user experience across diverse branches."
"Occasionally, there are certain delays in report generation."
"You won't find anything that can help you with the configuration part and other areas related to the product if you search for proper or exact details of Zscaler Cloud DLP online in very easy language."
 

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 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 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."
"I haven't seen it in a while, but it's at par with everything else licensing-wise."
"It was very reasonable."
"I only need the solution for IT staff, which makes it relatively cheap. If I deployed it for the whole company, it would be costly, so it depends on the number of users. Duo Security is affordable compared to other products in the segment."
"The pricing is pretty competitive. It's pretty cheap. Anybody can adopt it."
"You pay per user when using this solution and the pricing is fair."
"It is affordable for what's coming to the table with it, but in this day and age, the cost is looked at under a microscope, and companies need to very finely define what is needed versus what is critical. In some cases, it might not be cost-effective for a company to have it. In a lot of other cases, it is the cost of doing business."
"I rate the product pricing a seven out of ten."
"I am not aware of the pricing. There are two departments, and I don't have any information about them."
"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 product is a little more expensive than other tools."
"It has been relatively reasonable for what it does. Some of the additional license costs based on the advanced next-generation firewall functions are quite high, and they should have certain features ready and available as a baseline rather than having to purchase additional licenses for it. Overall, the cost seems reasonable."
"The cost is expensive. It depends on the number of users."
"My company is a Zscaler Private Access partner, so the customers pay for the license fees."
"Zscaler Private Access is extremely expensive."
"The technical support is good."
