How they differ

CISO Tribune files AIShield under AI model and agent security, AI firewalls and guardrails, and AI governance, and files Fiddler AI under AI model and agent security, AI governance, and AI firewalls and guardrails. AIShield sells AISpectra, which scans AI/ML models and notebooks and red teams ML and LLM systems for issues such as prompt injections and jailbreaks. AIShield also sells Guardian, with a ML Firewall for deployed machine learning applications and GenAI Guardrails that filter inputs and outputs of LLM applications. Fiddler AI sells Agentic Observability, ML Observability, Fiddler Centor Models and Agent Registry. Fiddler's Centor Models power guardrails and evaluations in-environment, with no external LLM API calls.

The two overlap on guardrails against prompt injection and jailbreaks, and both name PII handling. They differ in emphasis: AIShield centers on model scanning, red teaming and runtime firewalls, while Fiddler AI centers on observability for agents and predictive models, drift detection and audit evidence. Fiddler's audit evidence is aligned with frameworks such as GDPR, HIPAA and the EU AI Act. AIShield's AISpectra ties vulnerabilities to frameworks like MITRE ATLAS, OWASP and the EU AI Act.

Fiddler AI was founded in 2018 and is privately held. On January 27, 2026, Fiddler AI announced a $30 million Series C funding round led by RPS Ventures.
