Defend AI is a commercial ai threat detection tool by Straiker. Polymer AI Security is a commercial ai threat detection tool by Polymer. Compare features, ratings, integrations, and community reviews side by side to find the best ai threat detection fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Security teams deploying Claude, Copilot, or GitHub Copilot at scale need Defend AI because prompt injection and data exfiltration happen at subsecond speeds, and your existing DLP won't catch them. The >98.1% accuracy rate and multimodal threat detection across text, code, and documents means you're actually blocking agent-level attacks rather than guessing. Skip this if your LLM usage is still experimental or confined to ChatGPT free tier; the ROI only works once agents are making decisions that touch sensitive systems.
Security teams protecting SaaS environments where AI agents access sensitive data should pick Polymer AI Security for its identity-aware access control that treats AI identities as seriously as human ones, a gap most runtime platforms ignore. The platform maps audit logs directly to HIPAA, SOC 2, CCPA, and GDPR without manual translation, and its shadow AI detection catches unauthorized LLM usage before it becomes a breach. Not the fit for organizations still running primarily on-premises infrastructure or those needing broader vulnerability management beyond data access and classification.
Defend AI delivers runtime security guardrails with >98.1% accuracy and subsecond latency.
