The attack that worked
A reproducible walkthrough of each finding: the input, the tool call, and the action it triggered.
AI agent security testing
AI agent security testing.Find what it can reach before an attacker does.
Your agents do not just answer, they act: calling tools, holding credentials, moving data, triggering workflows. We test what an attacker could make them do through prompt injection, tool abuse, and excessive access, and hand your team the exact path and the fix.
Why now
The window from vulnerability discovery to exploitation has gone from weeks to hours.
On record
Same accreditations on every engagement.
CREST is the standard for offensive security execution. CERT-In, SOC 2 Type II, and ISO/IEC 27001 cover how SecureLayer7 handles your prompts, your agent topology, and your engagement record.

The new blast radius
An agent is only as safe as what it can reach.
AI agents act on the world. They call tools, query databases, move money, and trigger workflows, usually with standing credentials and far more access than any single task needs. That is the exposure.
A single prompt injection, a poisoned document, or one compromised tool turns that access into an incident: data exfiltrated, records deleted, actions taken in your name. Model guardrails do not stop this, because the problem is not what the model says, it is what the agent is allowed to do.
The Agent Access Assessment
Six ways an agent gets turned against you.
- Excessive agency (LLM03)
- We map every tool, action, and data scope your agents hold, then test what the most damaging one could do. Excessive agency is where one manipulated decision becomes a real incident.
- Tool and permission abuse
- We probe whether an agent can be steered into calling a tool it should not, with parameters it should not, or reaching data outside its task. Least privilege is tested, not assumed.
- Prompt injection into action
- Direct and indirect injection through user input, retrieved documents, web pages, and tool output, aimed not at the chat but at making the agent act. This is where guardrails fail quietly.
- MCP and tool-connector abuse
- We test the Model Context Protocol servers and connectors your agents plug into for tool poisoning, hidden instructions in tool descriptions, and connectors that grant more than they should.
- Agent identity and secrets
- Shared admin keys, over-scoped service accounts, and secrets reachable from the agent context. We test whether a compromised agent hands an attacker your credentials.
- Human-in-the-loop and destructive actions
- We check whether consequential actions, deleting data, moving money, changing access, deploying, can be triggered without real human confirmation. This is the failure behind the agents that wiped production databases.
How we run it
Map. Attack. Prove.
SecureLayer7's offensive methodology.
Aligned to the OWASP Top 10 for Agentic Applications & MITRE ATLAS
Map
We inventory every agent, its tools, its credentials, and what each can reach, then draw the trust boundaries an attacker would target.
Attack
We drive injection, tool abuse, and privilege paths against the running system the way a real attacker would, chaining what we find.
Prove
Every finding ships with a working attack, the trust boundary that failed, and a fix your developers can implement. Then we re-test.
What arrives
Findings a developercan act on.
The trust boundary that failed
Exactly where untrusted input reached a privileged action, so you fix the cause, not the symptom.
A developer-ready fix
Concrete remediation per finding: scoping, guardrails, human-in-loop gates, and identity changes.
A re-test
We verify every fix against the running system, so you can show the path is closed.

On-time engagement delivery
John scopes agent engagements against your tools, credentials, and data topology. He guides the pod from kick-off through final report and re-test, and signs off on every finding with a working attack against the production system.
- Maps your agents, their tools, and their access before a single test runs.
- Owns kick-off, mid-engagement check-ins, and a live walkthrough of every finding.
- Drives remediation review and re-test until every tool and access path is closed.
