Author infoRatingReview Summary
Information Technology Contractor at Insight global5.0I've used Cisco Duo extensively as IT support and later personally, finding it easy to set up, scalable, and reliable, with smooth MFA features and strong support; most issues stemmed from administrative handling, not the product itself.
Senior Network Engineer at a educational organization with 1-10 employees4.5I use Cisco Duo primarily for MFA, especially for email, appreciating its granular policy controls. It enhances security by preventing unauthorized access and credential sharing. My only complaint is the lack of alerts for telephony credits.
Chief Technology Officer at University of Redlands5.0We use Cisco Duo for multi-factor authentication to secure our assets. The Verified Duo Push feature enhances security. Although integration with Active Directory could improve, the setup is easy, and Duo outperforms alternatives like Microsoft Entra ID.
Senior Network Engineer at Shentel4.0I use Cisco Duo for centralized authentication, significantly saving time during onboarding and offboarding. While its Splunk integration could improve, its streamlined server management provides a notable ROI. We didn’t consider other solutions, opting directly for Duo.
Senior Iam Associate at Cognizant4.0I've used Cisco Duo for three years and find it easy to set up, reliable, and reasonably priced, with strong SSO and MFA capabilities, though it could improve in identity management and conversational AI features.
Senior Network Engineer Specialist at Zenith Comp Co.,Ltd.5.0I implemented Cisco Duo for VPN MFA and found it easy to deploy, cost-effective, and highly integrative. It's stable, scalable, and supports secure, passwordless access. Support is excellent, and customers benefit from per-user licensing across multiple applications.
Network Engineer at West Kentucky Rural Electric Cooperative Corporation, Inc.4.0I use Cisco Duo for MFA, appreciating its online and offline authentication features, which enhance security even when users travel. It needs smoother integration and push notifications. While helpful, it impacts productivity, lacking visible ROI due to login time.
Staff Network Engineer at a manufacturing company with 10,001+ employees4.0Cisco Duo enhances security primarily through its user-friendly phone notification system, particularly benefiting older users. While effective, occasional delays in notifications require improvements. Despite not seeing an ROI, I value its flexibility and ease of setup over alternatives.
