Pros & Cons at a Glance
Based on the data, Duo Security is the better option for organizations seeking a straightforward, cost-effective solution for multi-factor authentication and basic Zero Trust features, given its affordable $3 per user per month pricing and user-friendly experience. SentinelOne, however, stands out for enterprises needing advanced AI-driven endpoint protection and autonomous response, though its $45 per endpoint per year cost and potential for false positives may require careful consideration. I recommend Duo for smaller teams or those focused on access security, while SentinelOne is ideal for larger setups with complex threat environments, ultimately depending on your specific security needs and budget constraints.
