I’m an efficiency junkie. If a tool can shave 20 minutes off my deployment or help me refactor a messy codebase, I’m all for using it.
Lately, that means living in AI tools like Claude Code, Cursor, and GitHub Copilot. Honestly, I can’t imagine shipping code without them anymore. They make me feel like I have a superpower.
But as a Lead Security Engineer, those same superpowers are starting to haunt me at night.
I’ve spent my career thus far securing systems, human identities, and building perimeters. But in 2026, the perimeter has moved inside the IDE. Our developers are now running AI agents with production access, the ability to execute code, and the power to hit APIs - all while our traditional security stack sits there, completely oblivious and in the dark.
Why our current stack is blind (And Yours Was Too)
I’ve seen this firsthand in our own repos. We’ll be running a security audit and realize that an agent just quietly executed a series of local tools to "fix" a bug. No alerts. No logs in the SIEM.
From an architectural perspective, these agents behave more like Advanced Persistent Threats (APTs) than software:
- They use C2-like channels: Communicating via LLM and MCP (Model Context Protocol) calls that bypass standard proxies.
- They "Live off the Land": They don't need to download malware; they just use the legitimate tools already on the dev machines.
- The Identity Gap: Your EDR is looking for a virus. It isn’t looking for a "helpful" agent that just exfiltrated an .env file because it thought it was helping you debug a connection issue.
Why I’m Betting on Ceros (And Why You Should Too)
Ceros didn’t start as a corporate initiative; it started as a solution to the friction I saw every day in my own terminal (a reality shared by every developer on our team who has gone all-in on AI). The name is a tribute to Cerberus, the three-headed guardian, and a play on the Zero Trust DNA that has defined Beyond Identity for years. We built it to anchor the three pillars that crumble the moment an AI agent enters your workflow: Visibility, Identity, and Control.
The 5 Hurdles That Actually Worry Me (And How We Fixed Them)
- The "Who Did That?" Problem (Blast Radius Attribution): If an agent wipes a DB, who is responsible? Ceros provides AI Agentic Provenance. It deterministically binds every action back to a verified human on a verified device. No more "the AI did it" excuses.
- Secret-less Execution: I’m tired of seeing API keys in plaintext or floating in memory. Ceros vaults keys in hardware—they never move and never get copied.
- MCP "Dependency Hell": Connecting to a third-party MCP server is the new 'npm install' vulnerability. I need to know which servers my team is connecting to. Ceros lets us whitelist the ones we actually trust.
- Unauthorized Tool Execution: I want my agents to write code, not change firewall rules. Ceros enforces risk-based policies that block unauthorized tool calls from the endpoint before they can do damage.
- Real-Time Forensic Visibility: When an incident happens, "I don't know" isn't an acceptable answer for an auditor. Ceros captures every prompt and tool call for a full audit trail.
How It Actually Works (The Hardware-to-Human Binding)
The architecture is elegant because it doesn't just "watch" traffic. It ties every agent action to a hardware-backed identity.
- Identity: No phishable credentials. Developer identity is baked into every line of code.
- Control: Real-time device posture evaluations. You can revoke tool or model access mid-session if a device falls out of compliance.
- Visibility: A complete forensic record for compliance and debugging.
Think of it as the missing layer that powers forensics, enforcement, and audit for your AI ecosystem.
Why This Matters Now (The Reality Check)
Chasing agent behaviors is a losing game. As engineers, we know that the only way to solve this is at the source. Your IAM systems can control who accesses an agent, but they have zero visibility into what that agent is doing once it's running. Ceros bridges that gap by tying the agent to the hardware identity of the person running it.

The public preview is now open. We’ve been battle-testing this with early access partners and the feedback loop has been tremendous. As it turns out, I wasn't the only one worried.

Disclaimer: Yes, I work at Beyond Identity. But I’m writing this as a practitioner. I’ve seen the "black box" of AI agents, and frankly, the alternative is just crossing your fingers and hoping your developers don’t accidentally connect to a malicious MCP server. Personally I’d rather have control.
