TLDR: Pillar Security has launched its Secure AI Lifecycle (SAIL) Framework, a significant advancement in AI security. Developed with insights from leading cybersecurity experts across Fortune 500 companies, SAIL provides a structured methodology to manage over 70 AI-specific risks across seven critical phases of the AI development and operational lifecycle, aiming to ensure secure and compliant AI adoption.
Pillar Security, a prominent startup in the cybersecurity domain, has officially introduced its Secure AI Lifecycle (SAIL) Framework, marking a pivotal moment in the industry’s accelerating efforts to secure artificial intelligence operations. The framework, unveiled on July 7, 2025, is the culmination of collaborative efforts with cybersecurity experts from more than two dozen leading organizations, including industry giants like AT&T, Corning, Philip Morris, Microsoft, Google Cloud, SAP, and ServiceNow.
The SAIL Framework is designed to provide a robust strategy, comprehensive governance, and essential tools to ensure the safe and secure deployment and operation of AI and agentic systems. It aims to bridge critical communication gaps between AI development, MLOps, LLMOps, security, and governance teams, fostering a unified and proactive approach to AI security.
According to Chris Hughes, CEO of Aquia and a key contributor to the framework, ‘SAIL is a helpful tool for security and software practitioners building with and on AI systems.’ The framework distinguishes itself by harmonizing with and building upon existing industry standards, including the NIST AI Risk Management Framework, ISO 42001, OWASP’s Top 10 for LLMs, and the Databricks AI Security Framework. This integration ensures a comprehensive and adaptable resource for business and IT leaders navigating the complexities of AI security.
At its core, SAIL addresses the evolving threat landscape by providing a detailed library of over 70 mapped AI-specific risks, organized across seven interconnected phases of the AI lifecycle. It defines the necessary capabilities and controls for a resilient AI security program, thereby facilitating and accelerating secure AI adoption while ensuring compliance with industry-specific regulatory requirements.
The Seven Foundational Phases of the SAIL Framework include:
1. Plan: AI Policy & Safe Experimentation: This initial phase emphasizes aligning AI initiatives with business objectives, regulatory mandates, internal privacy policies, and ethical standards. It incorporates threat modeling to identify AI risks early, ensuring that data, models, and third-party components are introduced safely into development workflows.
2. Code/No Code: AI Asset Discovery: Addressing the growing concern of AI asset sprawl and ‘Shadow AI,’ this phase focuses on comprehensively discovering and documenting every model, dataset, prompt, AI asset, MCP server, and tool. SAIL advocates for automated discovery tools to promote policy awareness and centralize AI governance.
3. Build: AI Security Posture Management: This phase is dedicated to modeling system-wide security posture and prioritizing protections based on risk assessments. It helps users understand asset interactions and potential risk origins, preventing reactive security measures by identifying chokepoints, overexposed connections, and weak configurations early.
4. Test: AI Red Teaming: In this crucial phase, AI systems undergo rigorous adversarial testing and simulated attacks. The goal is to challenge assumptions, validate defenses, and pinpoint vulnerabilities before they can be exploited by real threats. SAIL’s approach relies on standardized taxonomies and trained offensive security personnel.
5. Deploy: Runtime Guardrails: This phase introduces real-time safeguards, including input filtering, output sanitization, and enforcement of runtime policies. Recognizing that AI behavior can shift post-deployment, live monitoring and enforcement are deemed essential for detecting anomalies, malicious inputs, or emerging risks.
6. Operate: Safe Execution Environments: Focusing on high-risk actions, this phase involves creating sandboxed environments for AI operations. Isolating AI execution limits the ‘blast radius’ in case of failures, particularly for autonomous systems capable of executing their own code or interacting with sensitive infrastructure.
7. Monitor: AI Activity Tracing: The final phase ensures continuous monitoring of AI behavior and performance to identify drift, respond promptly to incidents, and maintain regulatory compliance for transparency and accountability. This includes ongoing performance checks, drift detection triggers, and telemetry pipelines to support rapid investigation and reliable model updates.
