TL;DR: LLM security incidents are rising as models move into production, with one source estimate putting AI-related security incidents at 73% of enterprises in the last 12 months, while red teaming is shifting from single-prompt testing to multi-step chained attacks according to ZioSec. That shift means conventional evaluation programmes are no longer enough when agents can combine prompts, tools, and integrations across one attack path.
Editorial analysis by NHI Mgmt Group, based on content published by ZioSec: “LLM Red Teaming: Evaluations, Attacks, & Deep Chained Methods - Ziosec, Mindgard, Promptfoo Compared”.
By the numbers:
- 73% of enterprises experienced at least one AI-related security incident within 12 months, according to ZioSec.
- Organisations that use AI and automation extensively for security reported average breach costs of $3.84 million, versus $5.72 million for those that do not, according to ZioSec.
Key questions
Q: What breaks when LLM red teaming stops at single-prompt tests?
A: Single-prompt testing misses how attackers combine prompts, context, tools, and integrations into a sequence.
Q: Why do chained LLM attacks increase risk in systems with tools and integrations?
A: Because the model is no longer only generating text.
Q: How should security teams decide where to red team an LLM application?
A: Start with the workflow boundaries that create real authority: retrieval, external tools, connectors, and any action the model can trigger.
Practitioner guidance
- Build multi-step attack scenarios Create test cases that chain prompts, retrieval, and tool calls so the red team evaluates the full execution path rather than isolated responses.
- Separate evaluation from offensive testing Use repeatable evaluation for baseline safety checks, then run adversarial tests to measure exploitability, chaining, and unwanted side effects.
- Inventory every external integration Map the connectors, APIs, plugins, and action endpoints an LLM can reach, then decide which ones should be available to the model at all.
Bottom line: Deep chained LLM attacks exploit the gap between a model passing isolated tests and the same system failing when prompts, tools, and integrations are composed into one path.

Deep chained attack paths are the governance blind spot in LLM security: single-control testing assumes risk lives in one prompt, one model response, or one obvious failure point. That assumption breaks when an attacker can compose multiple benign-looking steps into a working exploit. The practitioner conclusion is that LLM security has to move from point testing to sequence testing.
A few things that frame the scale:
- Only 23% of IT leaders were very confident in their organisation's ability to manage security and governance for GenAI deployments, according to a 2025 Gartner survey of 360 IT leaders.
A question worth separating out:
Q: What is the difference between LLM evaluation and adversarial red teaming?
A: Evaluation checks whether a model meets defined quality, safety, or consistency criteria under structured test cases. Adversarial red teaming tries to break the system by simulating realistic abuse, including prompt injection, authorisation bypass, and chained exploitation. Teams need both because one measures expected behaviour and the other measures exploitability.
