6 Best Pangea AI Guard Alternatives for AI Security in 2026

Bundled pricing — you pay for the full security suite

Pangea's AI Guard is one module within their broader security platform (SecureAudit, AuthN, Embargo, Redact, etc.). Pricing is suite-level, not à la carte. You typically buy the full platform to get AI scanning — paying for capabilities you don't need to get the one you do.

Shallow prompt injection detection

Pangea's AI Guard focuses on content safety (toxicity, PII redaction, malicious URLs) more than adversarial prompt attacks. Its injection detection is basic pattern matching — it doesn't use multi-layer detection with semantic analysis or LLM-based judgment. Purpose-built injection tools catch significantly more attack variants.

No agent framework awareness or tool call scanning

Pangea treats AI scanning like any other API content check. It doesn't understand agent frameworks, tool call arguments, inter-agent delegation, or multi-step workflows. When an attacker injects through a tool's return value or exploits inter-agent communication, Pangea can't see the context.

Cloud API adds latency and data residency complexity

Every scan requires sending text to Pangea's cloud API. This adds latency per call and means your prompts traverse external infrastructure. For teams with GDPR, HIPAA, or data residency requirements, this creates a data processing relationship requiring DPAs and compliance review.

Strong at redaction, weaker at detection

Pangea's real strength is PII redaction — actually removing or masking sensitive data before it reaches the model. That's valuable. But detection of adversarial attacks (injection, exfiltration, escalation) is a different problem, and Pangea's approach treats it as a content safety problem rather than a security problem.

Purpose-built for AI agent threats vs. general security with AI bolted on.

Available independently without requiring a broader platform purchase.

Sophisticated injection detection and broad threat coverage beyond basic scanning.

Native support for agent frameworks and tool call scanning.

Enterprise prompt injection API with battle-tested detection, now part of Palo Alto Networks.

Self-hosted toolkit for LLM scanning with PII detection — the open-source alternative.

Open-source LLM output validation with a large library of validators.

Standalone cloud API for prompt injection detection with fine-tuned models.

Enterprise AI firewall with hallucination detection and content safety from Arthur AI.

If you need PII redaction specifically, Pangea does that well. Pair with Rune for agent security threats.

Fully self-hosted with PII detection, no vendor dependency.

Can I use Rune and Pangea AI Guard together?

Yes — and this is a common pattern. Pangea excels at PII redaction (actually removing/masking sensitive data before it reaches the model) and malware scanning on file uploads. Rune excels at agent security: prompt injection detection, data exfiltration through tool calls, secret exposure, and real-time threat monitoring. Use Pangea Redact in your data pipeline, Rune Shield in your agent pipeline.

Does Rune do PII redaction like Pangea?

No — Rune detects PII in model outputs and tool arguments and alerts you, but doesn't actively redact/mask data. If you need active PII redaction (replacing SSNs with [REDACTED] before the model sees them), Pangea Redact is genuinely the better tool for that specific job. Rune catches PII that leaks through despite your redaction layer.

Why not just use Pangea for everything?

Pangea approaches AI security as a content safety problem — scanning text for bad patterns. That works for toxicity and PII, but agent threats like indirect injection through tool returns, data exfiltration via encoded URL parameters, and privilege escalation through multi-step tool abuse require agent-level awareness that content scanning can't provide. Rune sees the agent context (tool calls, framework state, inter-agent messages), not just the text.

What's the honest case for staying with Pangea?

If your primary concern is PII redaction and content safety (toxicity, malicious URLs), and you're already on the Pangea platform for other security modules (AuthN, SecureAudit, Embargo), AI Guard is a natural add-on with zero additional vendor relationships. The case for adding or switching to Rune: you have tool-calling agents, need deeper injection detection, want agent-level visibility, or don't want to buy the full platform for one feature.
