About Custos — The bouncer for your AI agents
Custos is an open-source safety and control layer designed specifically for AI agents, acting as a reliable 'bouncer' for your applications. As AI agents increasingly interact with critical infrastructure, Custos sits directly between the agent and its tools—such as APIs, files, databases, shell commands, and MCP servers—to intercept and verify every single action before it is executed.
Built for teams deploying AI agents in real-world environments, Custos allows you to explicitly define rule sets determining what an agent is allowed to do, automatically blocking anything outside of those bounds. Furthermore, every action attempted or performed is recorded in a secure, tamper-evident audit trail. With native support for both Python and TypeScript, Custos provides developers with the robust security infrastructure needed to prevent AI agents from performing unintended or harmful actions.
Pros of Custos — The bouncer for your AI agents
- Acts as an interception layer between AI agents and critical tools like APIs, files, databases, shell commands, and MCP servers.
- Provides a tamper-evident audit trail recording every agent action.
- Open-source software built for teams running real-world AI agent environments.
- Supports both Python and TypeScript development stacks.
Cons of Custos — The bouncer for your AI agents
- Relies entirely on developer-defined rules to catch unexpected agent behaviors.
- Limited to Python and TypeScript language support based on current specifications.
- Requires integration work to sit between existing agents and their target tools.

About Privent 2.0
Privent 2.0 is a dedicated runtime data control solution designed specifically to secure n8n workflows. In standard AI workflows, agents frequently transmit raw, sensitive information—including emails, database records, API keys, and secrets—to Large Language Models (LLMs) on every run. While n8n's native Guardrails node can redact this information, that redaction is permanent, preventing the workflow from reclaiming the original data once processed.
Privent 2.0 resolves this issue by tokenizing PII and secrets before they reach the LLM, and then safely reversing the tokenization at a trusted sink to restore the original data. As an Official n8n Integration Partner, it is built for production teams running complex agent workflows that cannot afford a single leaked record. For teams requiring strict data boundaries and absolute compliance, Privent 2.0 also features a Local mode that runs entirely offline.
Pros of Privent 2.0
- Tokenizes PII and secrets before they reach LLMs, avoiding permanent data loss
- Safely reverses tokenization at a trusted sink to restore original data
- Offers a Local mode that runs fully offline
- Official n8n Integration Partner built specifically for production workflows
Cons of Privent 2.0
- Focuses specifically on n8n workflows, which may limit teams using other orchestration platforms
- Requires configuring a trusted sink to reverse the tokenization process
Frequently Asked Questions
How does Privent 2.0 differ from n8n's native Guardrails node?
While n8n's native Guardrails node permanently redacts sensitive information (making it unrecoverable), Privent 2.0 tokenizes PII and secrets before they reach the LLM, allowing the tokenization to be safely reversed later at a trusted sink.
Does Privent 2.0 support offline environments?
Yes, Privent 2.0 features a Local mode that runs fully offline, making it suitable for teams with strict security and compliance mandates.
Is Privent 2.0 officially integrated with n8n?
Yes, Privent is an Official n8n Integration Partner, designed specifically for production teams running AI agent workflows.
