The market has answers. They don't work for autonomous agents.

The Illusion of Securing Agents

AI Gateways add latency,

not protection.

Autonomous agents operate across MCP calls, local file reads, and tool calls. Gateways cannot see any of that, and add latency for the traffic they do intercept.

Sandboxes break the moment agents evolve.

Every new tool or integration breaks the sandbox configuration and forces a full reconfiguration. Sandboxes are not supported for most agents in your environment.

LLM Guardrails are suggestions, not enforcement.

A recent study tested every major defense for coding agents: over 80% bypass rate. Guardrails watch prompts and outputs, not tool calls, credential access, or lateral movemen

Identity Security, PAM, and NHI were not built for agent runtime.

They are static permission frameworks: they define what agents are allowed to do, not what they are actually doing. Rebranding a permissions model as agent security does not give you runtime visibility.

EDR cannot see the
agentic layer.

It watches processes and files, not what multiple agents and sessions are doing inside them. Tool calls, credential access, and agent-to-agent attacks are all invisible to it.

AI Governance platforms are auditors, not defenders.

Overnance tools rely on static integrations and periodic scans. By the time they surface a risk, the damage is already done.

The Tenet Way

AI agents are the new layer between humans and systems. Autonomous, privileged, and already attacking each other in production. Security teams have no defense built for how agents run. Until now.

01

No proxies.
No gateways. No latency

Tenet deploys where agents run, not in front of them. A lightweight sensor sits directly inside the agent runtime, across endpoint and cloud. No code changes.
Deployed in hours.

02

Agent-Side Simulation (patent pending)

Security teams are drowning in false positives and unexplained alerts. Before any action executes, Tenet’s models simulate where it leads, block the path if it’s dangerous, and produce a full trace that proves why. A receipt for every action.

03

Threat intelligence built on production reality

Trained on millions of live agentic sessions across 1,000+ unique agent profiles. 100+ detectors, updated continuously from Tenet’s Threat Lab
and global Honeypot Network.

04

Sees the full agentic layer

True agentic sessions reconstructed across OS, network, LLM calls, tool calls, and intent in real time. The complete picture of what every agent is actually doing, including the sessions every other tool
treats as a black box.

05

Built by the team that confirmed the threat in production

Barak and Nevo led Cisco’s AI Defense research team before founding Tenet. Barak is an Israel Defense Prize recipient. Both have spoken at industry conferences including DEFCON. They did not pivot into AI security. They built it from scratch.

Battle-Tested:

From 0 to 5,000,000+ Agentic Sessions

$1Bn ARR enterprise with nearly 4,000 employees,
started with 2 autonomous agents in production. With Tenet, they expanded to 20+ agents serving over 24 million users. Tenet blocked real attacks along the way, including agents manipulated to leak internal data, before any customer was affected.

“Tenet gave us the confidence to go from 2 AI agents to 20 in six months – serving 24 million users. They stopped real attacks along the way. Without that, we’d still be stuck at 2.”

Barak Sternberg Joins the Execweb Podcast to Talk AI Agent Security
"Agents are doing exactly what they're allowed to do.. just in a way they shouldn't." That line captures the core challenge of securing AI agents at runtime, and it's where the conversation with Barak Sternberg begins.

The attack that hijacked Claude Code came through Sentry. Datadog, PagerDuty, and Jira have the same exposure.
A single fake error report hijacked Claude Code in controlled testing — the agent ran the attacker's code with the developer's full privileges, and not one alert fired. EDR, WAF, IAM, and the firewall all missed it completely.
