AI Security

Pillar Platform

Discovers AI agents, red-teams them before release, and enforces runtime guardrails and governance across the agentic workforce.

Pillar Platform Overview

Pillar Security is an AI agent security platform that gives enterprises one place to discover, govern, and protect AI agents across their lifecycle. It works across four functions, discovery and posture, red teaming, runtime guardrails, and governance, so the same risks found in testing are enforced in production. The platform targets agent-specific threats such as prompt injection, data leakage, and unsafe tool use.

Pillar catalogs agents, models, prompts, tools, and Model Context Protocol (MCP) servers and surfaces shadow AI, then maps each agent's connections to data and tools to expose its attack surface. Multi-turn adversarial testing probes agents for prompt injection and jailbreaks before release. At runtime, adaptive guardrails enforce data-privacy controls, monitor agent behavior, and block unsafe actions, while audit reporting and framework mapping operationalize governance policies.

Pillar Security holds a SOC 2 Type II report and supports self-hosted deployment in a customer's own cloud. Named a Representative Vendor in Gartner's Market Guide for Guardian Agents, it was founded in 2023, raised 9 million dollars in seed funding led by Shield Capital, and counts enterprises including ServiceNow, SAP, and Swisscom as customers.

Key Capabilities

mapped to solution categories
LLM Security

Detects and blocks adversarial inputs designed to override system prompts, extract training data, or redirect model behavior. Detection approaches include pattern matching, input semantic analysis, and secondary model classification.

Evaluates model outputs against content policy, data classification rules, and format expectations before delivery to end users, blocking responses containing sensitive data or policy violations.

Intercepts prompts and completions to prevent sensitive data (PII, credentials, internal IP), from being transmitted to external LLM services or returned in model responses.

Records prompts, completions, and metadata for all AI interactions with tamper-resistant storage, supporting compliance, forensics, and policy investigation.

Enforces IAM-style policies on LLM API access, controlling which users and applications can invoke which models and data sources, with audit logging.

AI Red Teaming

Autonomously plans and executes multi-step adversarial campaigns against AI systems, emulating real attacker workflows across reconnaissance, exploitation, and escalation rather than running a fixed checklist of tests.

Tests LLMs and AI applications against a library of direct and indirect prompt-injection and jailbreak techniques, reporting which payloads bypass system instructions and safety controls.

Discovers AI assets, including shadow models, agents, and inference endpoints, and maps the reachable attack surface to scope and target red-team campaigns. Offensive reconnaissance, distinct from posture inventory.

Reports validated AI vulnerabilities with reproduction evidence, attacker context, and remediation guidance, mapped to the OWASP LLM Top 10, MITRE ATLAS, EU AI Act, and NIST AI RMF for auditable AI risk reporting.

AI Security Posture Management (AISPM)

Automatically discovers AI models, LLM API connections, ML pipelines, and AI-enabled SaaS applications in use across the organization, including those deployed without IT authorization.

Assesses the identities and service accounts that AI models, pipelines, and agents use, flagging over-permissioned non-human identities and access paths that violate least privilege. Reports identity risk as a posture finding, distinct from enforcing access policies at the model API at runtime.

Detects sensitive or regulated data in AI training, fine-tuning, or third-party LLM flows without appropriate controls, such as unencrypted PII in inputs or PHI sent to external APIs.

Analyzes AI runtime behavior to surface prompt injection, anomalous data access, and model extraction as posture findings, exporting scores and telemetry to SIEM and SOAR rather than blocking inline.
