Struggled to justify enterprise adoption but have valued broader developer accessibility
If I could change or add anything to improve C3 AI, I would suggest making it not just an AI platform, but a data and AI combined platform, as bringing in data management elements, governance, and cloud features is critical. The real AI and modeling represent only 20 percent of what is needed; there is over 80 percent in the rest of the world that should be addressed. Given Tom Siebel's deep understanding of corporate work and his network, integrating C3 AI with other ERP solutions such as Oracle, SAP, or Microsoft is essential. If C3 AI can be an enterprise platform, embedding more data elements and ensuring seamless integration with other ERP solutions would significantly enhance its capabilities and attractiveness. If someone told me that they have SAP, and C3 AI can seamlessly integrate the data and perform action calls between SAP, allowing me to operate on C3 AI as I would on SAP, that would be a killer feature for me. I would suggest avoiding traditional licensing sales as it is too expensive; the starting price is too high. Considering a subscription model or a pay-per-use model is the best business structure for AI or data solution vendors. The pay-per-use model benefits usage, as the more you use, the more successful you become with the platform.

Supports seamless authentication for users across multiple organizations and personal portals
The features I use in Cisco Duo include Duo Pushes to confirm my identity to the device, and eventually as MFA security was increased, I actually had to use exchange passcodes. Sometimes, I have to go into the site and get into Cisco Duo to retrieve the passcode, and many of them have been two-factor, where the sites send a passcode that I have to enter into Cisco Duo. It has been more of the latter. I have not seen issues with lagging or crashing on Cisco Duo's end; it was usually on the client end, often because someone set up a bad upgrade or there were connection issues with the Cisco Duo cloud through the administrative site.

Quotes from Members

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

Pros

"The biggest strength of C3 AI is how much it handles in one platform: data integration, model deployment, governance, monitoring, and application development."
"One of the best features C3 AI offers is that you do not need to learn Python or any specific machine learning programming language; you can use C3 AI with JavaScript."
"I have noticed improvements in efficiency, reduced downtime, and time saved for my team, as it is quite integrated through the source ML pipeline to report to general customer UI, functioning as one platform that takes care of everything, thus improving efficiency, optimization, and increasing project deliverables."
"In the first phase alone, there was approximately $90 million in savings, which reduced about 5% of inventory."
"I believe Cisco Duo is worth the investment, offering a good return on investment, as it is expensive but works very well without any downtime or high maintenance, and the support is also good."
"The biggest return on investment for me when using Cisco Duo is gaining time, as I don't have to look at ten different MFA apps, and I know it will work."
"It is a good solution for hybrid environments and VPN."
"Cisco Duo has made us more secure. We've managed to stop some threats with it and keep our users and devices safe."
"Without Cisco Duo, that would be very tough because Cisco Duo is a one-stop-shop, especially with their console."
"The thing that I appreciate the most about Cisco Duo is the ease of setup."
"Cisco Duo has unified the authentication method and really simplified it to where the end user doesn't have to interact with any authentication method."
"Cisco Duo has definitely improved my operational efficiency and reduced costs in areas like authentication and IT support, as evidenced by a reduction in security tickets since we don't see too many password change requests or forgotten password calls anymore."
 

Cons

"We even failed to open any doors for C3 AI; there are no smaller wins, learning opportunities, or process improvements, even if the main goals were not met."
"C3 AI can feel very enterprise-heavy. For smaller teams, it may feel excessive."
"The reason I chose eight out of ten is that as a user of C3 AI, I found the operational aspect not easy to understand; it is a bit tricky, and you should have more core knowledge to navigate C3 AI."
"However, I sometimes hear from colleagues that hallucination is an issue."
"Cisco Duo can be improved because people have their own personal mobile devices."
"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."
"The only time I really had some negative feedback for them was about the UI of their mobile app, but they improved it in the last version. It is good on the functionality side, but their pricing model is a little bit weird. Currently, there is no price advantage in signing up for yearly contracts. If you are on a monthly term or a yearly contract, you basically pay the same price, and that is very unusual. Normally, there is a discount when someone signs up for the 12-month system."
"Duo Security could improve by being more compatible with other vendors."
"It already integrates with lots of products, but it can integrate with more products. There should be easy integration with Cisco products because sometimes, it can be quite complicated."
"I think Cisco Duo could be improved by including email authentication, as there is currently only SMS, SMS push, and code generation, but having email authentication could be beneficial when you don't have a phone."
"Duo has some issues that we're trying to work through. For example, if I install it on a WordPress site and another admin needs to log in, they can't because Duo hasn't been set up for them. It doesn't appear that I can add permissions on a user-by-user basis. It's not obvious."
"If you want easier management, Duo wouldn't meet that need."
 

Pricing and Cost Advice

Information not available
"The pricing was a lot more than what we were paying for our previous solution."
"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."
"Our licensing fee is currently on an annual basis."
"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."
"Its price is reasonable. It is not highly expensive."
"I believe the licensing model is excellent as it offers flexibility to our customers, allowing them to adopt a crawl, walk, or run approach."
"You pay per user when using this solution and the pricing is fair."
"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."
