Cisco Duo Reviews Summary
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.
Technical Support Analyst at FBC Farm and Small Business Tax Consultants4.5I chose Cisco Duo for its reliable, easy-to-set-up MFA, essential for my firm's data security. It works seamlessly and offers great value. While offline access has a workaround, customer service is excellent, and scalability is smooth.
Director, Information Technology Technical Services at MOBILE INFIRMARY ASSOCIATION5.0I highly recommend Cisco Duo; its easy-to-use two-factor authentication significantly improved our security, preventing unauthorized access. It's stable, scalable, and supported by excellent customer service, making it a seamless solution that even saved us on insurance costs.
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.
Principle Cloud Architect at a tech services company with 11-50 employees3.5I used Cisco Duo for centralized IAM and VPN integration, valuing its phishing-resistant MFA and ease with Cisco product ecosystems, but noted limited enterprise adoption and no standout features compared to Okta or Azure Entra ID.
Network Security Engineer at a consultancy with 11-50 employees4.0I’ve used Cisco Duo for three years to secure our environment; it’s easy to deploy, scales well, and Identity Intelligence boosts visibility into identity risk. Downsides include phone and internet dependency, occasional downtime, integration/legacy challenges, phishing bypass risk, and rising subscription costs.
Cybersecurity Analyst at Broward County4.5I use Cisco Duo as my evolving identity provider, centralizing authentication and extending my security perimeter. It's stable and beneficial for managing identities, but I desire better integration with other Cisco products and improved identity correlation.
Manager, Business Unit at a tech vendor with 10,001+ employees5.0I've used Cisco Duo for over five years, mainly for MFA, and found it easy to deploy, reliable, and user-friendly, especially with push notifications, though pricing could be more competitive for basic use cases.
