Castle Device Intelligence vs Cisco Identity Intelligence: Side-by-Side Comparison (2026)

Castle Device Intelligence

SMB and mid-market teams protecting high-value accounts from credential stuffing and account takeover will see immediate ROI from Castle Device Intelligence, since its 99.5% accuracy device fingerprinting catches stolen credentials being used from unfamiliar devices in real time. The 150ms API response time means you're not adding latency to login flows, and the cookie-independent identification works even when attackers clear browser data. Skip this if you need behavioral analytics or post-breach forensics; Castle is built for preventing account compromise at the perimeter, not investigating it after the fact.

Cisco Identity Intelligence

Mid-market and enterprise teams drowning in identity alerts will find value in Cisco Identity Intelligence's AI filtering, which cuts noise by correlating user behavior across sessions and access patterns instead of flagging every anomaly separately. The tool maps cleanly to NIST DE.CM and DE.AE, meaning it prioritizes detection and analysis over response automation; you get visibility into risky privilege escalations and account takeover attempts, but incident mitigation still relies on manual session termination or user quarantine. Skip this if your team lacks the bandwidth to act on findings or if you need tight integration with your existing IAM platform; Cisco's strength is bolting onto what you have, not replacing it.
