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.

Strong privileged access controls have protected critical sessions and improved credential oversight
The best features of CyberArk Certificate Manager include its robust privileged access management capability, session monitoring, and strong defense against threat vectors. PSM, PIM, and application legacy connectivity for CyberArk Certificate Manager are probably the best in the market. The real-time threat intelligence feature helps with preventing security breaches as it never allows any privileged access to get into the application until you check out the user ID and password, effectively managing credentials. It also includes MFA and session monitoring, tracking who is checking out the password and credentials, which are capabilities that cannot be bypassed, thus neutralizing threat protection. I use features like PSM, PIM, session monitoring, and everything else with CyberArk Certificate Manager.

Strong security has protected my online accounts and keeps my access safe across platforms
In my opinion, the best feature Google Authenticator offers is the way it generates the code every one minute or thereabout, and the code keeps changing, which enhances security. I am very sure nobody can have access to my accounts without Google Authenticator. Google Authenticator has impacted my organization positively as I have first-hand assurance that nobody is breaking into any of our accounts or websites, and it saves a lot. It gives you that assurance; it makes you feel very safe. The security is top notch, and it is even amazing that it works without the internet. What is really measurable is that we do not get our things compromised now. It is more secure; it provides comfortability knowing that my account is safe, and I feel more secure.

Quotes from Members

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

Pros

"It is very easy for users to enroll, and there are a lot of insights that we get from using the app on devices that people use to authenticate."
"The stability and good performance of the MFA are notable since it responds within seconds, and perhaps the algorithm is good when compared to other providers' MFA algorithms."
"In my opinion, the best features Cisco Duo offers include its 2FA authentication, which is very good, everything is perfect about the features, it is very easy to use, and the integration with other systems is very good."
"Regarding the stability and reliability of Cisco Duo, it is very good."
"Looking back at my initial investment in Cisco Duo versus the total value it has delivered over time, I see that it has paid more than what we invested, so we are getting a good return and a good service with improved security."
"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."
"From the front end, it's very fast and it hasn't missed a beat, so to say."
"In the world of network security, it is outstanding and very strong."
"Certificate Manager has reduced the certificate expiration outages to almost nil, and since 2022, we have had almost zero major incidents wherein we saw a financial impact or business disruption due to an expired certificate."
"Since using CyberArk Certificate Manager, it saves a lot of time, reduces errors, and makes compliance much easier."
"The reporting analysis is what I liked the most about it; that was the nicest thing about it—it helped keep track of certificates and their status and where we needed to make improvements, update, replace things."
"Venafi takes care of automatically renewing and deploying your certificate so that you don't need to worry when it expires."
"CyberArk Certificate Manager has excellent capability in handling certification renewals; whenever you specify any validity period that needs to be renewed within certain days, it triggers automatically, and I appreciate that aspect."
"We use Venafi for PKI certificates."
"So, from the perspective of risk reduction, it can be directly quantified in the value for the customer."
"By using Certificate Manager, we have reduced our potential risk significantly due to certificate expiry, as all teams are getting emails before 60 days and 90 days, which is helpful."
"Google Authenticator has positively impacted my organization by improving security and productivity."
"Google Authenticator has helped save money, save time, and maintain reputation because of the security it provides."
"The security is top notch, and it is even amazing that it works without the internet."
 

Cons

"My experience with Cisco Duo's strong security authentication system is that sometimes there are difficulties, and sometimes users just won't be able to log in. We have to reset their password so they can use Duo."
"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 technical engineers in the first line of support should improve their knowledge."
"The cost will become expensive for large user accounts."
"However, I know that sometimes integrating it with the Linux environment is a bit of a pain."
"We first deployed Duo Security for our company with the VPN, and afterward, about a year later, we implemented it for a customer of ours where we offered infrastructure as a service. When I tried to establish a VPN connection through Duo Security, it did not function well on that version, which was the latest one at the time. So, I had to make a copy of the machine and then implement Duo Security with the VPN because it did not function well with the newer version."
"For upgrades, there should be a better notification of when they're coming out. We always have a testing phase, so we need to be ahead of it. It takes us longer before we can upgrade to the newest version."
"Regarding the Premier licensing, it is a little bit pricey, but it is in the market range with the competitors."
"There are quite a few different technical aspects of Venafi that I feel they just missed out on; I'd have to look at my notes for the specifics."
"In terms of scalability, given that we were in the situation where it was on-prem, there were certain limitations there."
"Regarding stability, I observed that in the last year, CyberArk Certificate Manager was down two to three times without any notification."
"There's definitely lots of room for improvement with Venafi. They have a website where we can suggest new features, and they need to take that a little bit more seriously."
"Venafi excels in automating certificate rotation and deployment but could enhance its offering by improving support for hardware security modules like Fortanix and providing more advanced, out-of-the-box integrations with public certificate authorities for DNS re-verification."
"Unfortunately, we didn’t receive a notification from Venafi because it wasn't configured correctly, which led to a loss of around 12 million dollars."
"For the stability of the solution itself, I would rate it a seven."
"The product was really good when it was a Venafi product. However, since its acquisition by CyberArk, there has been a lack of significant innovations. They are pushing for cloud adoption, but we prefer on-premises solutions due to regulatory concerns."
"I deduct one mark due to the lack of a backup and restore option."
 

Pricing and Cost Advice

"You pay per user when using this solution and the pricing is fair."
"I haven't seen any information on the pricing in four years, so I can't comment on that."
"I rate the product pricing a seven out of ten."
"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."
"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."
"The cost was reasonable. Licensing was pretty straightforward for a change."
"I am not aware of the pricing. There are two departments, and I don't have any information about them."
"The product’s pricing is reasonable."
"Venafi's pricing appears to be competitive within the market."
"The pricing model is complex, considering factors beyond the number of certificates. This complexity can make our payments to Venafi challenging if costs continue to rise. It is good but more expensive than the competitors."
