Best AI Agent Security Platforms for Cursor

Tragentics serves as a robust security platform for AI agents, ensuring that every agent is authenticated, securely retrieves keys from an encrypted Credential Vault—eliminating the need for agents to possess them directly—routes all communications through a content-blind relay, and maintains a metadata-only audit trail that spans various platforms and protocols. This platform does not perform any inference or execute agent logic, nor does it access or store the contents of agent communications. Each agent is assigned a unique permanent ID and an Ed25519 identity, with keys safeguarded at rest using AES-256-GCM encryption, while every interaction is authenticated, subjected to rate limiting, and logged solely as metadata, avoiding any capture of payload data. Moreover, Tragentics is protocol-agnostic, effectively managing traffic for existing agents, including MCP, A2A, ACP, OpenAI, ANP, and DID, providing a comprehensive solution for AI agent security. In this way, it enables organizations to enhance their security measures without compromising the functionality or privacy of their systems.

Enkrypt AI is an AI security and compliance platform built to protect generative AI applications, autonomous agents, models, data, and AI infrastructure. It provides security agents and controls for detecting vulnerabilities, preventing threats, continuously monitoring AI systems, and automating compliance processes. Enkrypt AI's red teaming capabilities dynamically generate use-case-specific attacks that adapt during testing to uncover security, safety, and brand risks that static evaluations may miss. The platform addresses threats including prompt injection, jailbreaking, data leakage, model inversion, adversarial attacks, policy violations, hallucinations, model drift, bias, toxic content, deceptive behavior, and unmonitored agent actions. Real-time guardrails inspect AI interactions and can stop threats as they occur while continuously adapting based on prompts and observed activity. Monitoring capabilities provide ongoing visibility into AI risk and compliance so organizations can identify issues, track protection effectiveness, and maintain evidence for audits. Enkrypt AI can translate internal organizational policies and external regulatory requirements into automated guardrails to reduce manual compliance work. Its product portfolio includes Agent Red Teaming, Agent Guardrails, an Agent Policy Engine, AI Data Risk Audit, MCP Scanner, and MCP Gateway, with solutions for customer-facing agents, frontier models, third-party AI risk, AI compliance, MCP security, and secure AI development. The company also maintains an LLM Safety Leaderboard that continuously red teams and benchmarks more than 200 AI models to help organizations evaluate model security and safety.

Palo Alto Networks Cortex Agentic Endpoint Security (AES) is an endpoint protection and AI security governance platform designed to secure autonomous agents, developer tools, and software components across enterprise devices. The software provides continuous discovery of AI applications, local language models, MCP servers, browser extensions, IDE plugins, and open-source packages that may introduce security risks. Its AI-native visibility capabilities help security teams identify unauthorized software and previously unmanaged AI tools operating within their environments. Context-aware risk analysis evaluates application behavior, permissions, software supply chain relationships, and access to sensitive resources. The platform maintains an AI Context Graph that connects discovered assets with relevant security information to support risk assessment and investigation. Governance tools allow administrators to establish security policies, restrict unsafe interactions, and remove insecure packages or extensions. Runtime protection monitors autonomous agent activity and blocks prohibited actions, malicious downloads, prompt injection attempts, and potential data exfiltration. Cortex AES integrates with Cortex XDR and Prisma AIRS to combine endpoint monitoring with AI application security and threat prevention capabilities. Organizations can deploy the solution as a standalone security product or alongside existing endpoint security infrastructure, with optional managed protection and investigation services from Palo Alto Networks Unit 42.

Pillar Security serves as a comprehensive AI security platform designed to safeguard the agentic workforce throughout the entire AI lifecycle, encompassing stages from development to deployment and ongoing runtime protection. By integrating business context during phases of discovery, testing, and protection, it ensures that security intelligence accumulates across various AI applications, including agents, models, prompts, frameworks, tools, MCP servers, skills, coding agents, and both SaaS and cloud environments. The platform enables organizations to identify and manage AI assets effectively, even those that are unapproved or fall under shadow AI, while also evaluating risks related to supply chain and overall security posture. Additionally, it maps out the attack surfaces associated with agentic systems and verifies critical vulnerabilities that need addressing. With its AI Security Posture Management features, Pillar scrutinizes interconnected agents, tools, permissions, data sources, prompts, models, and supply chain elements to reveal high-risk pathways, policy breaches, misconfigurations, and potential threats posed by coding agents, all of which enhance the understanding of the impact when a single component encounters a breach. Ultimately, Pillar Security empowers organizations to maintain a robust security framework while navigating the complexities of AI technology.

Opal Zero serves as a governance platform for AI agents that provides just-in-time access management by cataloging every agent and linking it with a responsible owner, evaluating access requests, and implementing decisions through the existing MCP gateway. This comprehensive solution allows organizations to maintain a unified inventory across various identity providers and AI platforms, including Okta, Entra, Anthropic, OpenAI, Bedrock AgentCore, and Cursor, revealing the permissions each agent holds and their respective ownership. The Risk Center highlights access that may be misaligned with intended use, unassigned, or excessive, directing concerns to the relevant owner while offering immediate corrective measures. Paladin assesses requests against established policies and contextual information, pinpoints the least-privileged access routes, adheres to ownership boundaries, and elucidates the rationale behind each resolution. By analyzing real user behavior, Policy Insights uncovers instances of redundant access and suggests enhancements to access policies, moving beyond sporadic fixes. Furthermore, Gateway Enforcement ensures that approved access decisions are implemented as specific, temporary policies within the existing gateway infrastructure, thereby fostering a more secure and organized environment for managing AI agents.

Harden AIF serves as a security platform specifically designed for AI coding agents, ensuring agent endpoint security by assessing tool calls prior to execution based on the developer's intent, session context, organizational policy, and the potential impact of the action proposed. This platform effectively safeguards against threats such as harmful commands, unauthorized access, accidental data transfers, exposure of sensitive information, misuse of privileges, and other risky actions undertaken by agents. By allowing legitimate operations to proceed without disruption, it can also safely redact sensitive information during supported workflows while preventing actions that deviate from the developer's intent or exceed their authority from executing. Harden AIF is compatible with a variety of widely used coding agents and development tools, including Claude Code, Codex, Cursor, Antigravity CLI, Kiro, Hermes, and OpenClaw, thus offering a uniform security framework throughout the agent ecosystem. This comprehensive approach not only enhances security but also fosters a safer environment for developers working with AI technologies.
