Best Guardrails AI Alternatives & Competitors

Wiz is the dominant cloud security platform and the leader in AI Security Posture Management (AI-SPM). It automatically discovers and maps shadow AI pipelines, model deployments, and training data across AWS, Azure, and GCP. Wiz identifies misconfigurations, exposed models, and sensitive training data risks across the entire AI supply chain. As the most widely adopted cloud security platform, Wiz is the de facto standard for securing enterprise AI infrastructure.

Protect AI provides end-to-end AI/ML security covering the entire model lifecycle. Its platform includes model scanning for vulnerabilities, supply-chain security for ML artifacts, runtime threat detection, and policy enforcement. Protect AI helps enterprises secure AI pipelines from development through production deployment.

Snyk is the developer-first security platform with deep AI security capabilities. Snyk for AI (evolved from DeepCode) scans code, dependencies, containers, and infrastructure-as-code for AI-specific vulnerabilities. Developers use Snyk to detect insecure model loading, prompt injection risks, and vulnerable ML library dependencies directly in their IDE and CI/CD pipelines. The most widely adopted security tool among AI developers.

Lakera provides real-time AI security that protects LLM applications from prompt injection, jailbreaks, data leakage, and toxic content. Lakera Guard is a low-latency API that scans inputs and outputs to detect and block attacks before they reach the model. The platform defends against the OWASP Top 10 for LLMs and is used by enterprises to secure customer-facing AI applications.

HiddenLayer provides AI security solutions that protect machine learning models from adversarial attacks, model evasion, and tampering. Its platform detects and prevents attacks targeting AI systems in real-time, offering model integrity verification and threat intelligence specifically designed for AI/ML workloads.

CalypsoAI provides AI security and governance tools for enterprises deploying LLMs. Its platform offers automated red-teaming, risk scoring, content moderation, and compliance monitoring. CalypsoAI helps organizations enforce security policies across AI applications with granular access controls and audit trails.

Robust Intelligence, acquired by Cisco in late 2024, provides AI validation and protection. Now integrated into Cisco's security portfolio, the platform offers automated red-teaming, continuous model validation, and runtime firewall protection for LLM applications. It detects adversarial attacks, data poisoning, hallucinations, and prompt injections across the AI lifecycle.

Prompt Security provides enterprise GenAI security across the entire AI stack. Their platform protects against prompt injection, data exfiltration, harmful content, and shadow AI usage. It works as a transparent proxy for all LLM traffic, enabling centralized security policy enforcement without changing application code.

Pangea is the "Twilio for Security" — a set of composable security APIs that developers embed directly into AI applications. It provides audit logging, data redaction, embargo compliance, IP reputation, and domain intelligence as simple API calls. For AI apps, Pangea's Redact API strips PII from prompts, its AI Guard detects prompt injections, and its Audit API creates tamper-proof logs of all AI interactions.

NVIDIA NeMo Guardrails is an open-source toolkit for adding programmable guardrails to LLM applications. It provides a modeling language (Colang) for defining conversation flows, topic boundaries, safety checks, and fact-checking rails. Integrates with any LLM and supports both input and output validation.

Arthur AI provides an AI firewall and monitoring platform.

Nightfall AI provides data loss prevention (DLP) for AI applications.

Lasso Security provides cybersecurity for large language models, protecting enterprises from LLM-specific threats. Their platform monitors and secures LLM interactions, detecting prompt injection, data leakage, and unauthorized access patterns. Lasso provides visibility into how AI is being used across the organization and enforces security policies.
