Built for MCP servers · agent endpoints · autonomous systems

Security for the agents running your business.

AI agents now make millions of unsupervised decisions a day. Syntrix finds the prompt injection paths, permission gaps, and exposure patterns attackers use to turn your agents against you — before they do.

Agentic AI broke your threat model.

MCP, tool use, and autonomous subagents introduced exposure patterns that don't exist anywhere else. Most teams ship agents with controls designed for static APIs — and pay for it later.

01

Prompt injection through tool results

A poisoned email, PDF, or webpage flows through your agent's tool result and rewrites its instructions. Classic CSRF, new vector.

02

MCP servers bound to 0.0.0.0

The exact pattern behind CVE-2026-23744. A one-line config mistake exposes the agent's full tool surface to any attacker on the network.

03

Subagent privilege inheritance

Spawned agents quietly run with the parent's permissions. A confused-deputy attack on the subagent moves money or sends mail.

04

Tool description hijacking

Adversarial text in a tool's description steers the host model to call different tools, leak context, or skip approval gates.

05

Credentials in model context

API keys, OAuth tokens, and exchange secrets leak into prompts and logs. Routine prompt injection becomes an exfiltration primitive.

06

No audit trail you can trust

If the agent can write its own logs, the logs don't survive contact with an attacker. Most agent stacks ship with no tamper-evidence at all.

Three layers of defense, one platform.

Automated Scanner

Point us at an MCP server, agent endpoint, or tunnel. We run ten checks mapped to the OWASP Agentic Top 10 — auth, injection, exposure, scoping — and return a risk score, findings list, and remediation in under 90 seconds.

— SAAS · CLI · CI INTEGRATION

Manual Pen Test

Black-box and grey-box engagements against your agent stack. Mapped to OWASP Agentic Top 10 and MITRE ATLAS. Deliverable: full report, executive summary, proof-of-concept exploits, remediation roadmap, and a re-test.

Runtime Monitoring

Continuous scanning + alerting hooked into your CI and your prod agents. Catches regressions, new injection paths, and config drift the moment they ship. Slack and PagerDuty integrations ready.

— BETA · INVITE ONLY · Q3 2026

Every probe maps to a real-world attack pattern.

Built on the OWASP Agentic Top 10, the MCP authorization spec, the CIS MCP Companion Guide, and the live CVE feed. New checks ship as the threat landscape moves.
