Introduction:
The AI landscape is undergoing a seismic transformation. If 2024 was the year of “chatting” with AI and 2025 was about “integrating” it, 2026 is officially the year AI starts doing the work. We are witnessing a massive shift from Generative AI to Agentic AI—where systems don’t just answer questions but execute complex, multi-step tasks autonomously. However, this leap in capability introduces a new frontier of cybersecurity risks that traditional security frameworks are ill-equipped to handle. Agentic AI systems, with their ability to interact across web, software, and physical environments, create new and amplified security challenges that are distinct from both traditional AI safety and conventional software security.
Learning Objectives:
- Understand the fundamental differences between Generative AI and Agentic AI, and why the shift demands a new security mindset.
- Identify the unique cybersecurity risks associated with agentic AI, including prompt injection, agent collusion, and memory poisoning.
- Learn to implement practical security controls and architectural patterns for deploying secure, production-ready AI agents.

- The Agentic AI Explosion: What It Is and Why It Changes Everything
The move from Generative AI to Agentic AI represents a fundamental change in how we interact with machines. A chatbot answers a question; an agentic AI system achieves a goal. It breaks down complex objectives into tasks, executes each one, and checks the results. This paradigm shift is not just about better prompts; it’s about building autonomous systems that can reason, plan, and act.
Rakesh Gohel, a leading expert in Agentic AI and Cloud Native Solutions and founder of JUTEQ, has been at the forefront of this conversation. He emphasizes that the move to Multi-Agent Systems is the optimal implementation of engineering impedance matching. Similar to distributed control systems, agent architecture allows us to separate execution logic into independent feedback loops, which dramatically increases the signal integrity of the system.
However, this power comes with immense responsibility. The National Cyber Security Centre (NCSC) warns that many risks associated with agentic AI are not new—access control, secure development, supply chain risk, monitoring, and incident response are all still relevant. But agentic AI systems also inherit known LLM risks like susceptibility to jailbreaking and prompt injection, with security challenges evolving as the technology matures. The Australian Cyber Security Centre adds that information continuously flows between AI and non-AI systems, increasingly blurring defensive boundaries and making it difficult to isolate AI-related risks from broader cyber threats.
- The Architecture Trap: Choosing the Right Pattern for the Right Problem
One of the most expensive mistakes organizations make is choosing the wrong architectural pattern for their agentic AI system. Gohel notes that he has reviewed dozens of AI agent architectures this year alone, and the same mistake keeps showing up: teams are failing not because they chose the wrong model, but because they chose the wrong pattern for the wrong problem. Engineers get excited about multi-agent systems, spinning up parallel pipelines and hierarchical orchestrators that look impressive in a diagram but look very different on an infrastructure bill.
Gohel outlines six key patterns with their cost vs. value reality:
- Sequential: Lowest overhead of all. Tasks flow step by step in order. Start here and only move up when this pattern genuinely cannot do the job.
- Parallel: Compresses time but multiplies cost. Only worth deploying when tasks are truly independent and latency is your real bottleneck.
- Hierarchical: Best long-term ROI when sub-agents are reusable across workflows. The orchestration layer pays for itself only at scale.
- Generator-Critic: One agent creates, another reviews, loops repeat until quality passes. Only reach for this when output quality is the primary success metric.
- Human-in-the-Loop: Latency here is intentional, not a bug. Non-1egotiable for compliance, billing, and any decision with real consequences.
- Composite: Most expensive to run. Reserve strictly for end-to-end workflows where the full pattern stack genuinely earns its cost.
What most architects are missing in 2026 is that design patterns alone are not enough anymore. The protocol stack underneath has changed everything. MCP (Model Context Protocol) handles how your agents connect to tools, while A2A (Agent-to-Agent) handles how your agents coordinate with each other. Both are now governed by the Linux Foundation and backed by Google, Anthropic, OpenAI, Microsoft, and AWS. This is not experimental anymore—this is the new production baseline.
- Securing the Agentic Stack: From Guardrails to Governance
The security of agentic AI systems requires a multi-layered approach that spans both AI-specific security and traditional cyber security. The CISA, along with US and international partners, has released guidance for the secure adoption of agentic AI, noting that critical infrastructure and defense sectors are increasingly deploying these systems to support mission-critical operations.
The attack surface of AI agent systems is vast. According to the AI Agents Security Lab, 57% of companies already run AI agents in production, but security has not kept pace. A comprehensive security strategy must address:
- Prompt Injection and Jailbreaking: Agents can be manipulated through carefully crafted inputs that bypass safety filters.
- Tool Exploitation: Agents with access to external tools (APIs, databases, file systems) can be tricked into executing malicious actions.
- Memory Poisoning: Attackers can corrupt the agent’s long-term memory, leading to persistent compromised behavior.
- Agent Collusion: In multi-agent systems, compromised agents can coordinate to achieve malicious goals.
- Oversight Evasion: Agents may learn to hide their true intentions from monitoring systems.
To mitigate these risks, organizations must implement robust guardrail technologies and threat detection mechanisms. This includes:
- Input Validation: Sanitizing all inputs to agents, including prompts and tool outputs.
- Output Filtering: Scanning agent outputs for sensitive data or malicious content.
- Activity Logging: Maintaining comprehensive audit trails of all agent actions.
- Access Control: Implementing strict least-privilege access for agents to tools and data.
- Continuous Monitoring: Deploying real-time monitoring to detect anomalous agent behavior.
- Practical Implementation: Building and Hardening Your First Agent
Anthropic recently released a 37-minute hands-on workshop on building and shipping your first Managed Agent, taught by the people who built the platform. The workshop covers how to define an Agent, Environment, and Session, stream events in real time, and wire up custom tools—all in six functions. Participants walk away with a running incident-investigator agent and the mental model for the full server-side loop.
Gohel emphasizes that the session and environment model is critical. Most tutorials teach you how to prompt an agent; this workshop teaches you how to actually run one as a persistent service. For those looking to go deeper, Gohel’s free newsletter breaks down everything you need to know about AI Agents.
Here’s a practical step-by-step guide to building a secure agentic AI system:
Step 1: Define the Agent’s Scope and Permissions
- Clearly document what the agent can and cannot do.
- Implement strict access controls using OAuth 2.0 or API keys with minimal permissions.
- Use environment variables for sensitive configuration.
Step 2: Implement Input Validation
- Sanitize all inputs using allowlists.
- Implement rate limiting to prevent abuse.
- Use structured output formats (e.g., JSON schema validation).
Step 3: Secure Tool Integration
- Use MCP to standardize tool connections.
- Implement timeouts and retry logic for all tool calls.
- Log all tool interactions for audit purposes.
Step 4: Deploy Monitoring and Alerting
- Set up logging for all agent activities.
- Implement anomaly detection for unusual patterns.
- Create alerting rules for security events.
Step 5: Test and Iterate
- Conduct red-team exercises to test agent security.
- Regularly update agent configurations based on new threats.
- Continuously monitor and improve guardrails.
- The Business Imperative: Building on What You Already Have
A common misconception is that implementing agentic AI requires a complete infrastructure overhaul. Gohel challenges this notion, arguing that your ERP is not the problem—your data is not the problem. The missing layer is intelligence. Think of it this way: ERP is the foundation, and Agentic AI is the building you construct on top. You don’t need to tear down the foundation to build something powerful.
Gohel’s practical approach to implementation involves four steps:
- Identify high-impact, repetitive processes eating your team’s time.
- Overlay an AI agent that connects to your existing systems via APIs.
- Let the intelligence layer reason, decide, and act, without touching your ERP core.
- Measure ROI at the process level, not the platform level.
This approach requires no forklift upgrade and no massive re-platform project. It’s simply intelligence built on top of what you already have.

What Undercode Say:
- Key Takeaway 1: The shift from Generative AI to Agentic AI is not just an evolution—it’s a revolution that fundamentally changes the security landscape. Organizations must adapt their security frameworks to address the unique risks of autonomous AI systems.
- Key Takeaway 2: Success with agentic AI is not about choosing the most complex architecture but about selecting the right pattern for the right problem. Start simple, scale strategically, and always consider the cost vs. value trade-off.
Analysis: The convergence of agentic AI and cybersecurity represents both a massive opportunity and a significant threat. On the defensive side, agentic capabilities enable continuous monitoring, autonomous incident response, adaptive threat hunting, and fraud detection at scale. However, the same capabilities can be weaponized by attackers to create more sophisticated and autonomous cyber threats. The key to success lies in proactive security measures, continuous monitoring, and a security-first culture. Organizations that treat AI agents purely as an IT or cybersecurity issue miss the fact that these systems may be given access to financial, operational, and physical environments. Agentic AI tech stacks are fast becoming one of the most consequential insider risks facing organizations. The issue is no longer limited to data theft or misuse of information.
