Half 2 in our collection on workload safety covers why understanding “who” and “what” behind each motion in your surroundings is turning into essentially the most pressing — and least solved — drawback in enterprise safety
In Half 1 of this collectionwe reached three conclusions: The battlefield has shifted to cloud-native, container-aware, AI-accelerated offensive instruments — VoidLink being essentially the most superior instance — particularly engineered for the Kubernetes environments; most safety organizations are functionally blind to this surroundings; and shutting that hole requires runtime safety on the kernel degree.
However we left one important thread underdeveloped: id.
We referred to as id “the connective tissue” between runtime detection and operational response. Id is turning into the management airplane for safety, the layer that determines whether or not an alert is actionable, whether or not a workload is permitted, and whether or not your group can reply essentially the most fundamental forensic query after an incident: Who did this, and what may they attain?
Half 1 confirmed that the workloads are the place the worth is, and the adversaries have observed.
Half 2 is concerning the uncomfortable actuality that our id programs are unprepared for what’s already right here.
The Assaults from Half 1 Have been Id Failures
Each main assault examined in Half 1 was, at its core, an id drawback.
VoidLink’s main goal is harvesting credentials, cloud entry keys, API tokens, and developer secrets and techniques, as a result of stolen identities unlock every part else. ShadowRay 2.0 succeeded as a result of the AI framework it exploited had no authentication at all. LangFlow saved entry credentials for each service it related to; one breach handed attackers what researchers referred to as a “grasp key” to every part it touched.
The sample throughout all of those: attackers aren’t breaking in. They’re logging in. And more and more, the credentials they’re utilizing don’t belong to folks, they belong to machines.
The Machine Id Explosion
Machine identities now outnumber human identities 82-to-1 within the common enterprise, based on Rubrik Zero Labs. They’re the silent plumbing of contemporary infrastructure, created informally, not often rotated, and ruled by nobody particularly.
Now add AI brokers. Not like conventional automation, AI brokers make selections, work together with programs, entry knowledge, and more and more delegate duties to different brokers, autonomously. Gartner tasks a 3rd of enterprise purposes will embrace this type of autonomous AI by 2028.
A current Cloud Safety Alliance survey discovered that 44% of organizations are authenticating their AI brokers with static API keys, the digital equal of a everlasting, unmonitored grasp key. Solely 28% can hint an agent’s actions again to the human who licensed it. And practically 80% can not let you know, proper now, what their deployed AI brokers are doing or who is accountable for them.
Each one expands the potential harm of a safety breach, and our id programs weren’t constructed for this.
What Workload Id Will get Proper — And The place It Falls Brief
The safety trade’s reply to machine id is SPIFFESand SPIRE, a regular that offers each workload a cryptographic id card. Quite than static passwords or API keys that may be stolen, every workload receives a short-lived, routinely rotating credential that proves it’s primarily based on verified attributes of its surroundings.
Credentials that rotate routinely in minutes turn out to be nugatory to malware like VoidLink, which will depend on stealing long-lived secrets and techniques. Companies that confirm one another’s id earlier than speaking make it far tougher for attackers to maneuver laterally by means of your surroundings. And when each workload carries a verifiable id, safety alerts turn out to be instantly attributable; you understand which service acted, who owns it, and what it ought to have been doing.
The place It Breaks Down: AI Brokers
These id programs have been designed for conventional software program companies, purposes that behave predictably and identically throughout each operating copy. AI brokers are basically completely different.
In the present day’s workload id programs usually assign the identical id to each copy of an utility when situations are functionally equivalent. You probably have twenty situations of a buying and selling agent or a customer support agent operating concurrently, they typically share one id as a result of they’re handled as interchangeable replicas of the identical service. This works when each copy does the identical factor. It doesn’t work when every agent is making impartial selections primarily based on completely different inputs and completely different contexts.
When a kind of twenty brokers takes an unauthorized motion, it’s essential know which one did it and why. Shared id can’t let you know that. You can’t revoke entry for one agent with out shutting down all twenty. You can’t write safety insurance policies that account for every agent’s completely different habits. And also you can’t fulfill the compliance requirement to hint each motion to a selected, accountable entity.
This creates gaps: You can’t revoke a single agent with out affecting your entire service, safety insurance policies can’t differentiate between brokers with completely different behaviors, and auditing struggles to hint actions to the accountable decision-maker.
Requirements may finally assist finer-grained agent identities, however managing thousands and thousands of short-lived, unpredictable identities and defining insurance policies for them stays an open problem.
The Delegation Downside No One Has Solved
There’s a second id problem particular to AI brokers: delegation.
Once you ask an AI agent to behave in your behalf, the agent wants to hold your authority into the programs it accesses. However how a lot authority? For a way lengthy? With what constraints? And when that agent delegates a part of its activity to a second agent, which delegates a thirdwho’s accountable at every step? Requirements our bodies are growing options, however they’re drafts, not completed frameworks.
Three questions stay open:
- Who’s liable when an agent chain goes unsuitable? If you happen to authorize an agent that spawns a sub-agent that takes an unauthorized motion, is the accountability yours, the agent developer? No framework supplies a constant reply.
- What does “consent” imply for agent delegation? Once you authorize an agent to “deal with your calendar,” does that embrace canceling conferences and sharing your availability with exterior events? Making delegation scopes exact sufficient for governance with out making them so granular they’re unusable is an unsolved design drawback.
- How do you implement boundaries on an entity whose actions are unpredictable? Conventional safety assumes you’ll be able to enumerate what a system must do and prohibit it. Brokers cause about what to do at runtime. Limiting them too tightly breaks performance; too loosely creates danger. The best steadiness hasn’t been discovered.
Id Makes Runtime Safety Actionable
In Half 1, we shared that Hypershield supplies the identical ground-truth visibility in containerized environments that safety groups have lengthy had on endpoints. That’s important, however alone, solely solutions what is going on. Id solutions who is behind it, and for brokers, we have to know why it’s taking place. That’s what turns an alert into an actionable response.
With out id, a Hypershield alert tells you: “One thing made a suspicious community connection.” With workload id, the identical alert tells you: “Your inference API service, owned by the info science crew, deployed by means of the v2.4 launch pipeline, performing on delegated authority from a selected consumer, initiated an outbound connection that violates its licensed communication coverage.”
Your crew is aware of instantly what occurred, who’s accountable, and precisely the place to focus their response, particularly when threats like VoidLink function at AI-accelerated velocity.
The Path Ahead: Zero Belief Should Lengthen to Brokers
The muse exists: workload id requirements like SPIFFE for machine authentication, established protocols like OAuth2 for human delegation, and kernel-level runtime safety like Hypershield for behavioral remark. What’s lacking is the mixing layer that connects these items for a world the place autonomous AI brokers function throughout belief boundaries at machine velocity.
This can be a zero belief drawback. The rules enterprises have adopted for customers and gadgets should now lengthen to workloads and AI brokers. Cisco’s personal State of AI Safety 2026 report underscores the urgency: Whereas most organizations plan to deploy agentic AI into enterprise capabilities, solely 29% report being ready to safe these deployments. That readiness hole is a defining safety problem.
Closing it requires a platform the place id, runtime safety, networking, and observability share context and might implement coverage collectively. That’s the structure Cisco is constructing towards. These are the sensible steps each group ought to take:
- Make stolen credentials nugatory. Exchange long-lived static secrets and techniques with short-lived, routinely rotating workload identities. Cisco Id Intelligence, powered by Duo, enforces steady verification throughout customers, workloads, and brokers, eliminating the persistent secrets and techniques that assaults like VoidLink are designed to reap.
- Give each detection its id context. Realizing a workload behaved anomalously will not be sufficient. Safety groups have to know which workload, which proprietor, what it was licensed to achieve, and what the blast radius is. Common Zero Belief Community Entry connects id to entry selections in actual time, so each sign carries the context wanted to behave decisively.
- Carry AI brokers inside your governance mannequin. Each agent working in your surroundings must be identified, scoped, and licensed earlier than it acts — not found after an incident. Common ZTNA’s automated agent discovery, delegated authorization, and native MCP assist make agent id a first-class safety object quite than an operational blind spot.
- Construct for convergence, not protection. Layering level instruments creates the phantasm of management. The challenges of steady authorization, delegation, and behavioral attestation require a platform the place each functionality shares context. Cisco Safe Entry and AI Protection are designed to do that work — cloud-delivered, context-aware, and constructed to detect and cease malicious agentic workflows earlier than harm is completed.
In Half 1, we stated the battlefield shifted to workloads. Right here in Half 2: id is the way you struggle on that battlefield. And in a world the place AI brokers have gotten a brand new class of digital workforce, zero belief isn’t only a safety framework, it’s the important framework that protects and defends.
