Machine Identities Outnumber Humans by 80 to 1: Why Your Organization Can’t Afford to Ignore the New Identity Security Crisis

Imagine you walk into your office tomorrow and, for every one of your colleagues, there are 82 invisible “workers” quietly performing tasks behind the scenes. These aren’t human coworkers—they’re bots, scripts, APIs, cloud workloads, and AI agents, each acting on behalf of your business. Some open doors to your most sensitive data. Some can trigger critical processes. Most fly completely under the radar.

Now, here’s the kicker: according to the just-released 2025 Identity Security Landscape by CyberArk, that’s no sci-fi scenario. This is the reality for organizations worldwide. Machine identities outnumber human users by more than 80 to 1, and the vast majority remain unknown, uncontrolled, and—worst of all—unsecured.

Let’s unpack what this means for the future of cybersecurity, why businesses are staring down the barrel of an “identity-centric” attack surface, and what you can actually do about it.

The Explosion of Machine Identities: How Did We Get Here?

It’s no secret that digital transformation has accelerated at a dizzying pace. Cloud adoption, DevOps, automation, and above all—the generative AI revolution—are reshaping how organizations operate. But there’s a hidden cost lurking beneath this progress.

Every application, API call, container spin-up, and AI workflow generates a new machine identity. These are the digital credentials used by non-human actors to access networks, data, and systems.

Here’s the jaw-dropping part: there are now 82 machine identities for every human user in the typical enterprise. That’s not a typo—it’s a tidal wave.

What Exactly Is a Machine Identity?

If “machine identity” sounds abstract, think of it like this:
A human logs in with a username and password. A machine might authenticate using tokens, SSH keys, certificates, or API keys. Both can hold privileged access. Both can be compromised. But, unlike humans, machines don’t forget passwords or call in sick—they operate silently and at scale.

Why Did Machine Identities Explode?

A few key drivers: – Cloud-first strategies: Every microservice, workload, and resource in the cloud needs an identity. – AI and automation: Each bot, script, and AI model requires credentials to act autonomously. – DevOps velocity: Modern development spins up and tears down resources at lightning speed, often without central oversight. – Shadow IT and “shadow AI”: Teams deploy tools and platforms outside of IT’s control, multiplying unmanaged identities.

And here’s why that matters: every new machine identity is a potential doorway for attackers. If you don’t see it, you can’t secure it.

Privileged Access Sprawl: The Silent Crisis in Enterprise Security

Let’s talk about privilege. In cybersecurity, “privilege” means the power to access sensitive data or critical systems. Privileged accounts are like master keys, and they’re prime targets for cybercriminals.

The CyberArk report exposes a staggering disconnect: – 88% of organizations define “privileged user” as strictly human. – But 42% of machine identities actually have privileged or sensitive access.

Translation: Nearly half of those machine identities can do real damage if hijacked, but most organizations aren’t treating them as a security risk.

The Real-World Impacts of Unsecured Machine Access

Think breaches are rare? Think again.
– 87% of surveyed organizations suffered at least two identity-centric breaches in the past year. Attacks ranged from supply chain compromises to stolen credentials.

Imagine an AI agent with admin rights being manipulated to leak sensitive data. Or a cloud workload’s API credentials falling into the wrong hands. This isn’t hypothetical; it’s happening in real time.

Why Aren’t Organizations Catching Up?

Several roadblocks persist: – Lack of tools: Traditional access management was built for humans, not fleets of machines. – Fragmented visibility: Machine identities are scattered across hybrid environments—cloud, on-premises, SaaS, and shadow IT. – Compliance pressure: Insurers and regulators are demanding better controls, but most organizations feel overwhelmed (88% are under new compliance scrutiny).

The Rise of AI and the Double-Edged Sword of Agentic AI Risk

If “machine identity” is the sleeping giant, AI is the rocket fuel pouring on the fire.

AI isn’t just automating tasks—it’s making decisions, acting autonomously, and spawning millions of new machine identities. The report predicts that AI will create the largest surge of privileged and sensitive access identities in 2025.

Shadow AI: The Risk You Can’t See

Sanctioned AI tools are just the tip of the iceberg. The real challenge is “shadow AI”—AI models or agents used without IT’s knowledge or approval.

Key stats from the study: – 68% of organizations lack identity security controls for AI. – 47% can’t secure shadow AI usage at all. – AI agents are increasingly a target for manipulation and abuse, especially if they hold privileged access.

Imagine a rogue AI agent, spun up by a developer, connecting to your database and extracting sensitive records. Without controls, you may never know it happened until it’s too late.

External Manipulation: A New Threat Vector

AI systems can be manipulated by adversaries—through prompt injections, data poisoning, or stolen credentials. If an AI agent with elevated permissions is compromised, the blast radius is huge.

Here’s why that’s dangerous:
Unlike humans, AI agents don’t question odd requests or spot social engineering. If manipulated, they will follow commands to the letter, no matter how damaging.

Identity Silos: The Hidden Enemy of Security Teams

So, why is it so hard to secure machine identities? The answer lies in identity silos and fragmented environments.

What Are Identity Silos?

Identity silos occur when different teams or platforms manage identities in isolation: – HR manages employee access – IT manages admin credentials – DevOps manages API keys – Cloud teams manage service accounts

This patchwork approach creates blind spots, making it nearly impossible to see—and control—every identity with privileged access.

The Impact on Business Resilience

The research is clear:
– 70% of organizations cite identity silos as a root cause of cybersecurity risk. – 3 out of 4 security leaders admit to prioritizing business efficiency over robust security.

Translation: In the race to move fast and innovate, security is falling dangerously behind.

The Compliance Squeeze: Insurance, Regulation, and Reality

Cyber insurance requirements and government regulations are turning up the heat.
– 88% of organizations are feeling increased pressure for enhanced privilege controls.

Failure to comply not only raises the risk of breaches—it can also mean higher premiums or lost coverage.

Why This All Matters: The Expanding Attack Surface

Let’s step back. What’s really going on here?
The digital world is no longer just about “people vs. threats.” It’s about identities—everywhere. Human and machine identities, often with privileged access, are doubling year over year.

And every unmanaged, unmonitored identity is an open invitation for attackers.

The New Identity-Centric Attack Surface

Key characteristics: – Expanding rapidly, fueled by cloud and AI – Privileged access everywhere—often undetected – Fragmented controls and visibility – Easy targets for adversaries using automation and AI themselves

In short: The attack surface isn’t just growing—it’s mutating.

What Organizations Must Do Now: Modernizing Identity Security

So, what can security leaders and IT teams do to regain control? Here are the most urgent steps—backed by experts and the latest findings.

1. Inventory Every Identity—Human and Machine

Start with comprehensive discovery. You can’t secure what you can’t see.
Map out all credentials: passwords, API keys, tokens, certificates, and more.

2. Apply the Principle of Least Privilege

Limit every identity—especially machines—to the minimum permissions needed.
Regularly review and revoke unused or excessive privileges.

3. Modernize Identity Security for Hybrid Environments

Invest in platforms built for both human and machine identity management (such as CyberArk’s Identity Security Platform).
Centralize visibility and control across cloud, on-prem, and SaaS.

4. Enhance AI and Automation Security

Monitor and secure all AI agents and automation tools.
Implement controls for both sanctioned and unsanctioned (shadow) AI.

5. Break Down Identity Silos

Foster collaboration between IT, security, DevOps, and business leaders.
Integrate identity management platforms wherever possible.

6. Prepare for Compliance and Insurance Demands

Keep up with evolving standards like Zero Trust and identity-centric frameworks.
Document controls and regularly audit access.

7. Educate Stakeholders

Train staff—technical and non-technical—on machine identity risks.
Make identity security everyone’s responsibility.

The Human Factor: Why Empathy and Awareness Are Critical

Here’s a reality check:
It’s easy to get lost in tech jargon and statistics. But behind every machine identity, there’s a human who created, manages, or relies on it. Security isn’t just about tools—it’s about awareness, ownership, and culture.

Let me explain:
When employees understand the why behind new controls, they’re more likely to follow best practices. When leadership prioritizes security alongside innovation, the entire organization wins.
