TL;DR: Gartner’s Hype Cycle for Secure Software Engineering, 2026 places agentic coding security, application security posture management, and software supply chain security in the same view, reflecting the shift toward AI-generated code, autonomous agents, and MCP-connected dependencies according to OXSecurity. The control problem is no longer just code quality but governance across instructions, tools, execution, and provenance.

Key questions
Q: What breaks when agentic code assistants are allowed to act without runtime controls?
A: The main failure is that static review cannot stop live misuse.
A: They extend trust into packages, MCP servers, models and execution services that may be reused automatically by the agent.
Q: What are the signs that ASPM is failing to control agent-generated application risk?
A: The warning signs are large numbers of findings, unclear ownership and repeated issues that never get prioritised into action.
Practitioner guidance
- Govern the agent execution path Treat instructions, tools, runtime context and output as separate control points for policy, logging and approval.
- Prioritise findings through ASPM Correlate scanner results, runtime signals and pipeline telemetry so teams can rank agent-generated risk by reachability, ownership and deployment impact.
- Inventory third-party model and MCP dependencies Track every package, model, server and external service an agent can call, then review whether each dependency has a defined owner and trust boundary.
Bottom line: Agentic coding security changes AppSec because the governing problem now includes instructions, tools, execution context and output, not only the code artifact.

Agentic coding security is becoming a control plane problem, not a tooling problem. The article reflects a shift from reviewing code artefacts to governing the instructions, tools and execution path that produce them. That means AppSec has to move closer to runtime control and delegated authority management. For practitioners, the important change is that security outcomes now depend on what the agent was allowed to do, not just what it wrote.
A few things that frame the scale:
- Breaches involving third parties rose to 48% of all breaches, a 60% increase on the previous year, according to Verizon's 2026 Data Breach Investigations Report.
- 92% of organisations expose NHIs to third parties, raising concerns about supply chain security, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: How should security teams govern agent permissions across AppSec and supply chain workflows?
A: Treat agent permissions like governed non-human authority. Limit tool access, track provenance, separate duties across build and runtime paths, and review whether each agent can reach data or systems beyond its current task. When those rights are not explicitly bounded, the delivery pipeline becomes harder to trust.
