Pillar Security FAQ
How does Pillar Security handle shadow AI and unapproved systems?
Pillar Security performs complete AI discovery to catalog all AI agents, models, prompts, frameworks, tools, and servers, including those deployed without oversight. It flags unsanctioned AI systems and compliance gaps instantly, allowing organizations to define approved models and block violations.
What specific types of AI risks does Pillar Security address at runtime?
At runtime, Pillar Security detects malicious intent, analyzes agentic behavior, enforces data privacy, and monitors every interaction. This includes identifying and protecting PII, PHI, credentials, and secrets, as well as tracking tool invocations and decision patterns to prevent data exfiltration and privilege escalation.
Can Pillar Security integrate with existing AI gateway frameworks?
Yes, Pillar Security integrates with leading AI gateway frameworks to add a security enforcement layer without requiring a re-architecture of the existing stack. It inspects prompts and responses in real time for sensitive data exposure, prompt injection, toxic content, and policy violations.
How does Pillar Security ensure that AI agents operate with least-privilege permissions?
Pillar Security tracks tool invocations across every agent session and validates that each agent operates within its intended permission scope. It flags actions that deviate from declared intent and catches identity mismatches when agents inherit overly broad access, helping to contain the blast radius of compromised behavior.
What is Agentic Red Teaming and how does Pillar Security utilize it?
Agentic Red Teaming involves executing multi-turn adversarial attacks against complete AI systems to test tool orchestration, permission escalation, and agentic workflows. Pillar Security uses this to validate vulnerabilities, prove exploitability with attack transcripts, and feed findings into adaptive guardrails for immediate protection.
How does Pillar Security manage governance for third-party AI and supply chain integrations?
Pillar Security extends governance controls to external AI providers, SaaS platforms, and vendor integrations. It validates third-party AI systems against an organization's security policies before they can access internal data, ensuring consistent security posture across the entire AI ecosystem.
What kind of remediation guidance does Pillar Security provide for identified vulnerabilities?
Pillar Security surfaces prioritized findings with remediation guidance for vulnerabilities identified in homegrown AI applications, including code repositories, model configurations, RAG pipelines, and prompt templates. It also provides step-by-step remediation for issues discovered on agentic endpoints, such as overly permissive access or hardcoded credentials.
Does Pillar Security offer continuous optimization for its protective measures?
Yes, Pillar Security features continuous guardrail optimization. It automatically refines protective measures by continuously leveraging insights derived from red teaming exercises and real-world AI interactions, ensuring that defenses remain effective against evolving threats.
