ROI

Sentiment score
5.9
Cisco Duo enhances security, reduces costs, and improves efficiency with multifactor authentication and simplified management, boosting ROI and satisfaction.
Sentiment score
4.9
Users save time and costs, with simpler setup and fewer security issues, when using Tailscale instead of traditional VPNs.
We were able to implement zero trust extremely quickly because of the platform and its ongoing developments, including Cisco Duo Network Gateway, which enabled that transition to zero trust extremely quickly.
Global Associate Director, Services at a leisure / travel company with 1,001-5,000 employees
Not having MFA means you cannot put a price tag on that because you will be hit with ransomware immediately.
Director at a tech vendor with 10,001+ employees
The biggest return on investment was the ease of use for the end users to have that secondary authentication when logging into the critical systems.
Manager, Data Center at a real estate/law firm with 11-50 employees
Previously, networks with FortiGate were used, and that forced us to spend on hardware. With Tailscale, that type of investment is not necessary.

Room For Improvement

Cisco Duo needs better integration, competitive pricing, improved usability, enhanced device compatibility, and easier deployment to satisfy users.

It lacks some dynamic identity management features compared to other products such as SailPoint.
Senior Iam Associate at Cognizant
Not only has the product been very good and we have done fewer support cases, but I think support overall has been very fast.

Tailscale could be improved with more advanced network visibility and monitoring tools, cleaner pricing tiers for scaling teams, and enhanced built-in reporting for device posture and controls for enterprise environments.
System Engineer at a healthcare company with 11-50 employees
At my apartment, I can do 2-gig networking, but when I connect via the exit node, and I'm wired in somewhere else, and that place also has 2-gig networking, I'm at max getting half of my speed.
Software engineer
I would like Tailscale to provide more censorship-resistant options, such as Shadowsocks or VLESS, as fallback protocols.

Our company benefits from all those features of Cisco Duo with confidence, and we feel very secure with it in terms of authentication of our logins.
Vice President at Next Info Tech Solutions Inc
The benefit of having a complete passwordless environment in our organization is that it's gotten people away from using the sticky note under their keyboard - which is a huge problem.
Director, Technology at Deer Creek High School
The security is valuable, as there are many providers available, but Tailscale fulfills the requirements that we had, allowing us to access and expose internal apps without exposing them to the general internet.

The most valuable features are the Zero Trust architecture, peer-to-peer connectivity using WireGuard, easy deployment and setup, access control for granular permissions, single sign-on, subnet and routing, exit nodes, and cross-platform support.

Tailscale's security is fabulous, especially the access control features and the ability to use existing OAuth accounts for access.

Charles Slaustas - PeerSpot reviewer
Information Technology Contractor at Insight global
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.
Adeniyi Stephen - PeerSpot reviewer
DevOps Engineer at CloudKite.io
Secure access has simplified hybrid connectivity and has unified multi-cluster workflows
I would say that in terms of Tailscale, if I have so many tailnets I need to connect to, there are some issues in the login process that need a little bit of attention from the Tailscale team. Sometimes, you would probably need to restart your entire system for it to connect. As a DevOps as a Service engineer, I have so many clients that are using Tailscale, and I would need to connect to maybe five different tailnets because they are different clients. Client A might have a Tailscale, Client B, Client C, and so on. When changing between tailnets, sometimes it hangs. Sometimes you might need to restart your entire system. This is a bit of a headache in that aspect. However, I believe if you are just using a particular tailnet, just one, then it is quite easy and there won't be any headache. For me, I think it can be improved in the aspect of having multiple tailnets to connect to. A good refresh on the Tailscale side and the backend side to refresh the connection anytime there is a new connection to be made would be helpful. Instead of needing to restart the system, it should be able to refresh itself. The connection side and connecting to multiple Tailscale instances can be problematic, and sometimes you have to restart your system when switching between them. The ACL sometimes is like another language on its own entirely. It is fine, but they need to make it in a YAML format instead of the current format because it is quite new and something you have to go and study. If they can make it like a YAML format, that would be better. Aside from the switching which I mentioned and the fact that you have to relearn their ACL, if the ACL could be in a YAML format instead of JSON format, that would be beneficial. I don't think there is much they can do about the switching of tailnets, but if they can have a YAML format of the ACL, that would be good. Every other thing is a ten out of ten. The connection-wise is easy to set up and easy to install. It is good to have things connected all together from on-premises, from so many environments, and even exit nodes as well. It is good overall. The pricing, I think Tailscale can be a little bit on the higher side. It is not for teams with just small users. If you want to set it up for small users and a small startup, I don't think you can afford it and might need to go to other open-source alternatives. It is good for teams that have maybe fifty plus users or one hundred users. In terms of pricing, I would say it is on the higher side, but it is worth it. The price is worth the functionality. As a user, I would say it is more on the higher side, but based on its functionality, it is worth the price.
