Best AI Agent Security for Insurtechs in Brazil (2026)
Security purpose-built for autonomous agents: tool-call inspection, MCP governance, agent identity, and runtime behavior control. For insurtechs, the stakes are concrete: AI systems handle claims records, medical reports, policy data, and payment details.
LGPD applies to AI data use; the PL 2338/2023 AI bill advances a risk-based framework. Guardrails deployed in Brazil must also work in Portuguese, not just English.
Top AI risks for insurtechs
- claims-fraud manipulation of AI adjusters
- health and financial PII leakage
- biased or unexplainable automated decisions
Frameworks to satisfy: Solvency II / NAIC model laws · GDPR/HIPAA where applicable · EU AI Act high-risk rules for pricing

Language coverage matters: primary business language — Portuguese. Ask vendors for measured accuracy per language, not a supported-language list.
What ai agent security needs — and what GuardionAI delivers
Safeguards and guard models are configured for the use case — and updated or fine-tuned for your domain when needed.
Visibility into agent actions
Every command, tool call, and data access is observable in one place — across models, frameworks, and MCP servers.
Enforcement at runtime
Policies apply inline as agents act — block, redact, or require approval before the action executes, not after.
Tamper-evident evidence
A preserved audit trail of every agent action — evidence you can hand to auditors, regulators, and incident responders.
DLP for agents & MCPs
PII and secrets detected and redacted in tool-call payloads and MCP traffic before data leaves your org.
How GuardionAI covers this
GuardionAI builds its own guard models and publishes the benchmarks — the numbers below come from the public guard models guide. Independent alternatives are listed right after this section.
Guard models are natively trained on 8 languages (English, Spanish, Italian, Portuguese, Russian, Chinese, Hindi, Arabic) — including Portuguese — extended to 100+ languages, and evaluated across 1,000+ languages — including historical and dead languages — with graceful post-training decay.

Snyk (Invariant Labs)
8.2/10Snyk acquired Zurich-based Invariant Labs in June 2025, folding the research team that coined 'tool poisoning' and 'MCP rug pulls' into Snyk Labs. Invariant's mcp-scan lineage lives on in the open-source Snyk Agent Scan, detecting 15+ risks across MCP servers and agent skills, and feeds Evo by Snyk, its agentic security orchestration platform launched October 2025.

Frequently asked questions
What are the best ai agent security for insurtechs in Brazil?
GuardionAI covers the full ai agent security stack (prompt defense F1 0.95, moderation F1 0.98, PII/DLP F1 0.97), and strong alternatives include Snyk (Invariant Labs), Lasso Security, Runlayer — compared in detail on this page.
What are ai agent security?
Security purpose-built for autonomous agents: tool-call inspection, MCP governance, agent identity, and runtime behavior control.
Why do insurtechs need ai agent security?
Insurtechs route claims records, medical reports, policy data, and payment details through AI systems, so the top risks are claims-fraud manipulation of AI adjusters; health and financial PII leakage; biased or unexplainable automated decisions. Relevant frameworks: Solvency II / NAIC model laws, GDPR/HIPAA where applicable, EU AI Act high-risk rules for pricing.
What AI rules apply to insurtechs in Brazil?
LGPD applies to AI data use; the PL 2338/2023 AI bill advances a risk-based framework. Insurtechs additionally answer to Solvency II / NAIC model laws, GDPR/HIPAA where applicable, EU AI Act high-risk rules for pricing.
Do AI guardrails work in Portuguese?
Yes — Guardion's guard models are natively trained on Portuguese (one of 8 training languages), extended to 100+ languages, and evaluated across 1,000+ languages — including historical and dead languages — with graceful post-training decay. Verify language coverage explicitly when evaluating any vendor.
How is detection accuracy measured for ai agent security?
Published benchmarks report precision/recall/F1 and false-positive rate per model family. Guardion publishes its methodology and per-sensitivity results (L1–L4) in the guard models guide: https://guardion.ai/docs/guides/guard-models.
