Kirin (Knostic)
Coding-agent runtime security and governance enforcement product. Targets Cursor, GitHub Copilot, and other AI-coding IDEs. Per the Knostic blog post, Kirin’s stated capabilities:
| Capability | Maps to Agentic AI Security Capability Maturity Model — A 2026 Practical Proposal |
|---|---|
| Hidden prompt-injection detection in code/context | D4 Runtime & Guardrails |
| Malicious agent rules-file analysis (Cursor / Copilot rules) | D6 Data, Memory & RAG (Cognitive File Integrity extension to rules files) |
| Rogue IDE extension detection | D8 Supply Chain & AI-BOM |
| Typosquatted package blocking | D8 Supply Chain & AI-BOM |
| MCP server validation + CVE checks | D5 Egress & Network, D8 Supply Chain |
| Destructive agent action blocking | D3 Control & Least-Agency |
| Continuous policy enforcement at runtime | D4 Runtime, D7 Observability |
| Single dashboard tracking MCP usage, rule changes, policy violations | D7 Observability & Detection |
Where Kirin sits in the Agentic AI Security Reference Architecture (2026)
A coding-agent-specific overlay that touches the Runtime, Egress, Data (rules files), and Observability planes. Conceptually similar to a coding-agent EDR. Closest OSS analogue is LlamaFirewall (PromptGuard 2 + AlignmentCheck + CodeShield), which Kirin is not directly comparable to but plays an adjacent role.
Strengths / Weaknesses
Strengths: targets coding-agent-specific threats (rules-file poisoning, IDE extension marketplace, typosquats) that broader AI security platforms don’t sharpen on. Single dashboard for MCP/rule/policy view.
Weaknesses (vendor-marketing-stated, uncorroborated): not benchmark-published; no AgentDojo-class evaluation cited; no head-to-head with LlamaFirewall, AgentGateway, or Cursor’s own Rulesets enforcement.
