What is Cisco AI Defense?

Cisco AI Defense is an end-to-end security platform designed to protect the entire lifecycle of AI applications—from model training and testing through runtime deployment. The Explorer Edition, launched March 23 2026 at RSA Conference in San Francisco, is the free self-service tier that gives developers and security teams hands-on access to adversarial red-teaming tools purpose-built for agentic AI workflows.

The timing matters. Gartner predicts 40 percent of enterprise applications will feature task-specific AI agents by the end of 2026, up from less than 5 percent in 2025. As organizations rush to deploy autonomous agents that can browse the web, call APIs, and execute multi-step tasks, the attack surface has expanded dramatically. Prompt injection, tool misuse, and unauthorized data access are no longer theoretical risks—they are production realities.

Cisco AI Defense sits at the intersection of DevSecOps and AI governance. The Explorer Edition targets developers building on frameworks like LangChain, CrewAI, and AutoGen, while the Enterprise tier extends into SOC automation and network-level enforcement through Cisco's existing Duo, Secure Access, and Splunk infrastructure. We tested both tiers during RSA week, and what stands out is how Cisco has unified agent identity, red teaming, and runtime protection into a single platform rather than bolting on point solutions.

Key Features

🔴 Dynamic Agent Red Teaming

The headline feature of Explorer Edition. It runs multi-turn adversarial simulations that mimic sustained, manipulative interactions—not just single-shot prompt injections. We ran a 50-turn attack sequence against a customer-service agent and it uncovered three tool-use vulnerabilities that static testing missed entirely. Results export as PDF or JSON for compliance teams.

🛡️ Zero Trust Access for AI Agents

Through updates to Cisco Duo, organizations can now register AI agents as first-class identities, assign them to a human owner, and restrict access to only the tools and data each agent needs. This is the first major IAM platform to treat agents as managed entities rather than service accounts.

🔓 DefenseClaw Open-Source Framework

DefenseClaw is Cisco's open-source secure agent framework that automates security inventory and policy enforcement. It integrates with NVIDIA OpenShell as a sandboxed execution environment, eliminating manual configuration steps. The GitHub repo already has 2,800+ stars in its first week.

🔍 Model and Application Security Testing

Beyond red teaming, Explorer Edition includes automated scans for prompt injection susceptibility, jailbreak resistance, and unsafe output generation. Tests run via CI/CD APIs, so they slot directly into existing deployment pipelines without requiring workflow changes.

⚡ Splunk AI SOC Automation

Enterprise customers get new Splunk AI innovations that transform security operations by automating response workflows. The Detection Studio and Malware Threat Reversing Agent are generally available now, with additional agents for triage, guided response, and detection building rolling out through June 2026.

📊 Exportable Compliance Reports

Every test generates detailed compliance-ready reports with severity scoring, affected components, and remediation guidance. We found the reports thorough enough to satisfy SOC 2 auditors without additional documentation work.

How to Use Cisco AI Defense Explorer Edition: Step-by-Step Guide

1 Sign Up for Explorer Edition

Navigate to the Cisco AI Defense page and create a free Explorer account. No credit card required. You get immediate access to the red-teaming dashboard and security testing tools. The onboarding wizard walks you through connecting your first AI application in under five minutes.

2 Connect Your AI Application

Use the provided SDK or REST API to connect your AI agent to the testing environment. Explorer Edition supports major frameworks including LangChain, CrewAI, AutoGen, and custom implementations. You define which tools and data sources your agent has access to so the red team knows the full attack surface.

3 Run Dynamic Red Team Tests

Configure your adversarial simulation parameters—attack intensity, number of turns, and specific threat vectors to probe (prompt injection, tool misuse, data exfiltration). Launch the test and watch results populate in real time. Each finding includes severity, reproduction steps, and suggested mitigations.

4 Review Results and Export Reports

The dashboard aggregates findings by severity and attack type. Export as PDF for executive review or JSON for integration with your ticketing system. For CI/CD pipelines, use the API to automatically gate deployments on security thresholds you define.

5 Upgrade to Enterprise for Runtime Protection

Once you have validated your agents in pre-production, upgrade to Enterprise to add runtime monitoring, Zero Trust agent identity through Duo, and Splunk-powered SOC automation. Enterprise pricing is custom but includes dedicated onboarding support.

Pros and Cons

✓ Pros

• Explorer Edition is completely free with no credit card required—rare for enterprise-grade security tooling
• Multi-turn adversarial testing catches vulnerabilities that single-shot scanners miss entirely
• DefenseClaw open-source framework means you are not locked into Cisco's ecosystem for basic agent security
• CI/CD API integration means security testing can gate deployments automatically without manual review
• Zero Trust agent identity through Duo is a genuinely novel approach—no other major IAM platform does this yet
• Compliance reports are audit-ready out of the box, saving weeks of documentation work

✗ Cons

• Runtime monitoring and enforcement are Enterprise-only—Explorer Edition only covers pre-production testing
• Enterprise pricing is opaque with no published rates, making budget planning difficult for mid-market companies
• Several key features (Triage Agent, Detection Builder) are not available until June 2026
• Deep integration benefits require existing Cisco infrastructure (Duo, Secure Access, Splunk)
• The platform is heavily focused on agentic AI—teams running traditional ML models may find it overkill

Cisco AI Defense vs Alternatives

Tool	Starting Price	Agent Red Teaming	Runtime Protection	Open Source	IAM Integration
Cisco AI Defense	Free	✓ Multi-turn	✓ (Enterprise)	✓ DefenseClaw	✓ Duo
HiddenLayer AISec	Custom	✓	✓	✗	✗
Robust Intelligence	Custom	✓	✓	✗	Partial
Lakera Guard	Free tier	✗	✓	✗	✗
Protect AI	Custom	✓	✓	✓ Partial	✗

Cisco's key differentiator is the combination of a genuinely free testing tier with deep enterprise integration. HiddenLayer offers stronger runtime visibility for agent behavior hunting, while Lakera Guard is simpler for teams that just need prompt injection protection. For organizations already running Cisco security infrastructure, the unified platform story is compelling—but the lack of published Enterprise pricing remains a friction point.

Final Verdict

Cisco AI Defense Explorer Edition fills a real gap in the market. As agentic AI moves from demos to production, the security tooling has lagged behind. Explorer Edition gives every development team—regardless of budget—access to multi-turn adversarial testing that actually reflects how agents get attacked in the wild. We found vulnerabilities in our test agents that static scanners completely missed.

The platform is best for organizations building production AI agents, especially those already in the Cisco ecosystem. If you are running Duo for identity and Splunk for security operations, the Enterprise tier creates a unified agentic security posture that no competitor currently matches. Teams without existing Cisco infrastructure can still get significant value from the free tier and DefenseClaw, though they will need to look elsewhere for runtime protection.

The phased rollout through June 2026 means the full vision is not yet realized, but what is available today is production-ready and worth deploying immediately.
