Featured Reviews

Thomas Botts - PeerSpot reviewer
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.

The solution enables seamless security management and fosters a learning environment
Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions. For the solution stopping us for e-learning, I appreciate the concept yet need more resources or courses in Mexico, preferably in Spanish. Certifications are easy, however, I require more real-world environments and instructors.

Quotes from Members

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

Pros

"As a former employee, I think it's top-notch when it comes to protecting internal and external threats and preventing unauthorized access to the network."
"They are users who, as mentioned before, utilize RDPAP and MDPAP. It includes functionalities related to finance, specifically in single sign-on."
"I love Duo Security's push notifications. It's simple, fast, and secure. From the user's perspective, the solution is seamless. The security aspect is great."
"It's a lot easier for our end users to connect to our network. You don't have to type in a code. You get push notifications, that's probably the best thing about it. The fewer clicks they have to do to be online, the better it is. They can easily get into the network and do remote work."
"It meets our security needs very well. It is easy to use, and documentation is also available. It is also very stable and scalable, and its support is also very good. We are satisfied with this solution."
"The feature of Cisco Duo that I appreciate most is the push notifications. They are great."
"Cisco Duo scales with the growing needs of our organization by making it easy to acquire more licensing, especially with an enterprise agreement, which allows built-in growth and minimizes worries about licensing as we expand."
"The two-factor login is great. I receive a message and just have to press okay."
"Cloudflare, in my opinion, was easy to implement."
"Cloudflare Access is part of the Zero Trust philosophy."
"The best feature is rate limiting. If I'm expecting 500 visits per hour, Cloudflare will limit the requests if I suddenly get 50,000."
"Clover is the best product globally."
"I'm very satisfied with the environment and the dashboard."
"Cloudflare is by far the most effective solution that I have come across."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Cloudflare is simple to use."
 

Cons

"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."
"I'd like to see it integrated into other applications. I know there are some integrations, but I haven't been able to explore that any further."
"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."
"They could just continue to add more integrations."
"Reducing or eliminating the "telephony credits" system used by Duo would be great."
"Duo was clearly purchased, and Cisco has a lot of other panels for their Firepower products, et cetera. They need to continue bringing it, Umbrella, and the endpoint pieces even more together and make the integration a little more seamless among all of them."
"The technical engineers in the first line of support should improve their knowledge."
"Sometimes, it's a little harder for customers to adopt."
"Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions."
"Cloudflare DDoS has poor technical support."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"They don't have a person to provide support for customers using the solution under their free plan."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"When there are any dynamic changes in complex applications, the tool takes a lot of time, making its analytics-related area a major matter of concern where improvements are needed."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
 

Pricing and Cost Advice

"I haven't seen it in a while, but it's at par with everything else licensing-wise."
"I believe the licensing model is excellent as it offers flexibility to our customers, allowing them to adopt a crawl, walk, or run approach."
"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."
"Overall, the pricing is fair. Customers can wrap it into their Enterprise Agreement, making it easier for them to solve their issues."
"I haven't seen any information on the pricing in four years, so I can't comment on that."
"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."
"I rate the product pricing a seven out of ten."
"The cost was reasonable. Licensing was pretty straightforward for a change."
"The solution is not that expensive."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution's pricing lacks transparency."
"The pricing of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."
"The prices are slightly expensive."
"Cloudflare Zero Trust Platform's pricing is good."
"My company has to make yearly payments towards the licensing costs attached to the solution. There are no hidden charges apart from the licensing costs of the solution."
