Agentic AI Security

Agents do not just answer, they act. When an agent holds credentials, calls tools, and writes to systems, a security failure is an action taken, not a wrong answer displayed. We threat model, test, and harden agentic systems before that action is taken for an attacker.

Definition

What is agentic AI security?

Agentic AI security is the discipline of securing AI systems that take actions: agents that hold credentials, call tools, browse, write to databases, and send messages. The risk model is different from a chatbot. An agent with a mail tool can be steered by a poisoned document into exfiltrating data. An over-scoped MCP server can turn a read request into a write. A purchasing agent can be redirected by instructions hidden in the content it retrieves. BD Emerson threat models, tests, and hardens these systems: the agent, its tools, its memory, and the runtime controls around all three.

Identity and credentials

Threat modeling for agent architectures

A structured map of what your agent can do, what it can reach, and what an attacker gains at each point: tools, credentials, memory, retrieval sources, and the blast radius when any one of them is compromised.

MCP server security review

MCP servers hand agents new capabilities, and every server is attack surface: its permissions, its input handling, what it exposes, and what happens when a malicious server or a compromised dependency joins the roster.

Tool and permission scoping

Least privilege applied to agents: each tool call gated by scope, each credential limited to the task at hand, and destructive actions separated from read paths so a hijacked agent cannot spend, delete, or send beyond its box.

Prompt injection at the orchestration layer

Direct and indirect injection tested where it matters: instructions hidden in retrieved documents, web pages, emails, and tool outputs that steer the agent while the user sees nothing unusual.

Memory and context poisoning

Agents that remember can be turned against you. We test whether poisoned entries persist across sessions, spread between users, and quietly change behavior long after the original input is gone.

Agent identity and credential handling

How the agent authenticates, what it holds, and for how long: token scope and lifetime, secrets in context windows, delegation chains, and whether actions are attributable to the agent or to the human who asked.

Our approach

Our approach

01

Map the agent surface

We inventory agents, tools, MCP servers, credentials, and data paths, then build the threat model that decides where testing effort goes first.

02

Test like an attacker

Injection, tool abuse, memory poisoning, and credential theft are attempted against the running system, chained the way a real adversary would combine them.

03

Harden the architecture

Findings become concrete changes: tighter tool scopes, isolated credentials, approval gates on destructive actions, and guardrails that hold at runtime rather than in policy documents.

04

Verify and retest

Fixes are retested against the original attack paths, and the final report maps every finding to OWASP LLM Top 10 and NIST AI RMF with proof of impact.

Our Advantage

Why BD Emerson for agentic AI security

Testers who build agents

The team that tests your agents also ships agentic systems in production. The attack paths we try are the ones that actually exist, not the ones from a slide.

Offensive security pedigree

The same practice that runs our penetration testing and red team work runs these engagements: human-led, proof-driven, and documented so findings survive engineering review.

Framework-ready findings

Everything maps to OWASP LLM Top 10 and NIST AI RMF, so results feed your risk register, your SOC 2 or ISO 42001 program, and your customer security reviews without translation.

We had a hard time finding the right company to partner with in support of our compliance journey. Some vendors sell the idea that they do the work, but then you end up doing everything. The ambiguity is what killed our last project. BD Emerson’s team has such great technical knowledge and understands the standard so well that they made us comfortable with moving fast. This has led to us closing major enterprise customers that were previously out of reach because of security and compliance.

Tom Watkins

CEO @ AMI AssetTrack

Lead an enterprise initiative to overhaul the organization's technology stack from ecommerce, corporate tech, and corporate security.

Supported ISO 42001 exercise and served as internal auditor.

Rubrik's privacy and compliance team began with the backbone of BD Emerson. BD Emerson supported building out the privacy program, GRC (ISO 27001, SOC 2, CMMC, FedRAMP), and the appsec function.

We needed a partner who could move quickly, without sacrificing precision. BD Emerson brought the expertise, structure, and speed we were looking for. Their team became an extension of ours, embedding themselves across the organization, guiding us step by step, and giving us confidence in areas we hadn’t tackled before. The internal audit they conducted was so detailed that even the external auditors called it out. Achieving ISO 27001 with zero nonconformities says everything you need to know about the quality of the partnership.
