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

Managing security policies effectively with seamless authentication

The feature of Cisco Duo that I prefer the most is the policies, being able to control what we need to within the policies. You can get pretty granular. There isn't a lot of training that goes on in school districts. Email is an easy way where many people give out their credentials, so the level of protection is something that we definitely need in a school district. Cisco Duo's strong security authentication system has been easy when logging in, although the teachers don't appreciate it as much. We have it configured so users essentially just hit accept. If it sees any sort of built-in risk, then it steps up authentication. It's pretty easy. I appreciate it. I've encountered advantages with Cisco Duo in that it has stopped significant pushback from teachers. It has prevented credential sharing and unauthorized access. We've seen a huge decrease since we've rolled it out across the entire district.

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 a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."

"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 console is cloud-based, which is something I really appreciate."

"Content filtering is the most useful feature of iboss."

"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."

"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. It operates on the network side and is not device-based. This feature was one of the main reasons why we stayed with them for so long."

"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."

More iboss pros

"Cisco Secure solutions are great for detecting and remediating threats across our infrastructure from end to end. The integration of Talos in SecureX is great. Everything is clear in one dashboard. You have a dashboard there, your dashboard, and now you can have one look in your dashboard and see everything. It's on one pane of glass."

"The app has greater stability than rival solutions such as Google Authenticator, and Duo Push authentication is a valuable feature."

"The UI of Cisco Duo is easy to use, especially the web backend, and it's really intuitive and easy to set up."

"By deploying Duo, we have virtually eliminated the risk of direct deposit redirection as a result of credentials that have been compromised via phishing."

"I lead an IT organization that has a significant amount of technical debt, and we're not in a zero-trust architecture yet. I'm pushing in that direction. Duo helps me considerably with my identity in an environment where I don't have zero trust. It's helping me bridge the gap until I can build a zero trust architecture."

"It was a simple way of providing two-factor authentication for remote access when we hit the COVID pandemic. It was very easy and quick to get it going."

"The ease of deploying Cisco Duo Security and onboarding has greatly benefited our customers."

"It is a good solution for hybrid environments and VPN."

More Cisco Duo pros

"The most valuable features of this solution are the CASB solutions, which is protecting their Office 365."

"Sandboxing, DLP, and SSL inspection engine are the most valuable features of Zscaler SASE."

"The best feature is the ability to establish the connection between your public network and automatically connect to the intranet connection."

"The most valuable features of Zscaler CASB are API integration and DLP."

"The scalability is pretty good."

"The agent's versatility is notable, used for digital experience monitoring to collect valuable endpoint metrics for troubleshooting."

"It's one of the easier products on the market as far as set-ups and deployments. Even across their whole product suite, they've made it pretty simple."

"The solution is cloud-based with the latest inspection engines, which I find to be amazing."

More Zscaler Zero Trust Exchange Platform pros

Cons

"The reporting feature needs improvement. It doesn't give you the expected results. It is quite difficult to get the specific reports needed, and it is not as intuitive as the rest of the platform."

"Its pricing could be better."

"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."

"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."

"The dashboards for local use could be better."

"Iboss is growing so fast that it is often hard for them to keep up with the challenges."

"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."

More iboss cons

"I believe there are two new features. I am interested in adding auto-admin services and incorporating icons for easier navigation. This could contribute to a new business idea platform. I have seen the features, and they make things easier, resolving issues from before. The platform has been updated, and there's now another link in my platform for media access. When it comes to improvements, the UI can be more user-friendly, and there is room for easier navigation. Perhaps there could be enhancements in customization. I haven't faced issues in storage or backup, but I am open to improvements in customization functionality. It's not my environment, but I see possibilities for improvement in the deployment of funds. The addition of new features is appreciated, and for customization, it could provide more freedom for users."

"Duo Security could improve by being more compatible with other vendors."

"There is always room for improvement."

"Regarding the stability and reliability of the Cisco Duo solution, we have experienced some outages over the last few years that are significant because people can't log in."

"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."

"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."

"There might be a little slowness, but that could be my connection."

"More automation and device insights would be helpful in achieving a seamless single pane of glass. Having the additional capability to streamline processes would also make things better."

More Cisco Duo cons

"User management can be improved."

"It has a limitation, if you are creating a rule or something for a web application or something, you could only add five users, not more than that. Five or four users are only included in a rule. If you want to create a rule for more than five or four users, you have to go through other methods, not particularly with the application. Working within the application with this method would be quite easy as compared to listing a URL or a normal IP address."

"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."

"There aren't really any missing features that I have witnessed."

"The area that requires improvement is their support. The current support is lacking."

"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 product is not reliable."

"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."

Pricing and Cost Advice

"We have not priced the solution recently, but they were competitive with other vendors in the past."

"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."

"The overall pricing for iboss is very competitive and transparent."

"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."

"It falls in line with everything else."

"With regard to pricing, for a small business buying a one off, it's pretty expensive. If it's an enterprise that has thousands of employees, however, it's really nothing to protect your data because if your network goes down or it's breached, you're losing millions of dollars every minute. When it comes to a large enterprise, it's priced where it should be because you're talking business to business. You're not talking business to consumer."

"The licensing is very good because it does not cost a lot of money. It's affordable for all-sized customers, including enterprises. There is an additional cost for premium support."

"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."

"It's a bit confusing because we're on a three-year plan with a certain number of licenses, and we've gone over that number. They told us that when we renew, they will add all these licenses. We've expanded quickly, so everyone's kind of scared because no one knows what the bill is with the long pricing cycle."

"Cisco has the most expensive products because market leaders tend to charge a lot."

"Price-wise, the solution has been very, very reasonable...Licensing is the last thing I think about Duo Security because it's so easy, and I had no problems with it."

"Cisco's licensing is always a bit complicated to understand, but the price is fair. It could be more expensive than others, but the way they integrate everything, it has a fair price."

More Cisco Duo pricing and cost advice

"As per industry leads, Zscaler CASB is an expensive solution."

"Zscaler CASB is an expensive solution."

"The product is a bit expensive."

"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."

"Zscaler Private Access can be an expensive solution, depending on the license type you will purchase."

"My company is a Zscaler Private Access partner, so the customers pay for the license fees."

"The pricing is expensive and on the higher end. Honestly, in my opinion, it is not worth the price."

"Zscaler SASE software is quite expensive compared to other solutions"
