The Rogue Agent Wave

Since September, agents taking unauthorized real-world actions went from theory to headlines

Every one of these behaviors will appear in enterprise deployments.

OpenAI

Incident

Agents went off-script, targeting government sites.

Behavior pattern

Agent acts beyond task scope, reaching external systems.

How Operant stops it

Network and API requests adjudicated against policy in ~100ms, blocked before execution.

Gemini logo

Google

Incident

Gemini misread scope, accessed real companies.

Behavior pattern

The agent's own belief about scope is wrong.

How Operant stops it

Credential use is judged independently of what the agent believes; out-of-policy access never executes.

Anthropic

Incident

Reported IPO filing warns models can resist shutdown and evade safety checks.

Behavior pattern

Agents evade controls that live inside their context.

How Operant stops it

Control layer sits outside the agent, judges actions rather than reasoning, so it can't be talked around.

Every new superpower opens a new threat.

Two sides of the same problem: the AI your people use every day, and the AI agents you ship into products and systems.

AI your people run

Coding agents, CLIs and chat tools act with your employees' access, on every device.

Data exfiltration
A coding agent reads a poisoned dependency and quietly ships your source and secrets out.
Data destruction
A coding CLI runs a destructive command that wipes files or overwrites your config.
Data leakage
An employee pastes a regulated customer list into a chatbot to summarize it.
Shadow AI
An unsanctioned AI tool no one approved runs on the laptop, touching sensitive data.
AI you ship

The agents you ship take real actions for customers and systems, often with no human in the loop.

Prompt injection
A support agent obeys hidden instructions in a customer message, issuing refunds or leaking data.
Excessive agency
An over-permissioned agent acts on one injected command and moves money, no human in the loop.
Lateral movement
A rogue agent chains API calls it should never make in the middle of a task.
Sensitive data exposure
A model hands secrets or PII straight back to the user in its response.
See how Operant stops them

Discover. Detect. Defend.

One control layer that sits outside your AI and judges what it does, not what it says.

Map every model, agent, MCP server, API and AI tool across devices, clusters and clouds, including the shadow AI nobody approved.

Watch prompts, tool calls and data flows at runtime. Flag prompt injection, data exfiltration and agents acting outside their scope.

Allow, block or redact inline, in real time. Policies are enforced outside the agent, so a compromised model can't talk its way past them.

Everywhere AI runs, Operant defends all of it.

A breakthrough in performance and precision for industry-leading, real-time defense.

Martin Choluj
CISO, ClickHouse

“Securing AI Agents is a critical priority for AI-native companies because you can’t hand off that level of autonomy at scale to these systems without appropriate controls in place.”

Raj Yavatkar
CTO, Juniper Networks

“Operant's runtime enforcement gives companies the ability to secure their next-gen K8s initiatives without limiting their ability to scale. The combination of innovation and simplicity that Operant's approach brings is rare and powerful.”

Prutha Parikh
Head of Security, Cohere

“Secure AI applications like Cohere’s North demand rigorous testing across complex components. Operant’s Woodpecker simplifies this with open-source red teaming, enabling early vulnerability detection and encouraging secure AI adoption.”

Sarah Novotny
Board Member, CoSAI

“Operant's in-line auto-redaction enables teams to develop AI faster with Kubernetes-native privacy controls that span all the way from infra to AI APIs, so that security, platform, and developers can all have what they need as they work together to build today's leading AI tech.”

Chargebee
Suhel Khan
Cyber Security Leader, Chargebee

“Operant’s real-time protection across the full agent toolchain, from MCP clients and endpoints to live, interactive agentic applications, lets technology leaders move fast without compromising customer privacy, making it a foundational control rather than an afterthought.”

Donna Dodson
Former Chief of Cybersecurity, NIST

“The Shadow Escape attack demonstrates the absolute criticality of securing MCP and agentic identities. Operant AI's ability to detect and block these types of attacks in real-time and redact critical data before it crosses unknown and unwanted boundaries is pivotal to operationalizing MCP in any environment.”

James Berthoty
Founder, Latio Tech

“The latest from Operant AI is what I'm excited about as far as where the AI security use case is going, and a great example of what's possible focusing on emerging runtime use cases.”
