AI agent security statistics show adoption outpacing control. In McKinsey's 2025 survey, 62% of respondents said their organizations were at least experimenting with AI agents. In a Gartner survey of 297 cybersecurity leaders in the second quarter of 2026, 54% had no defined approach to limiting AI agent access or relied on predefined human access. Lab results agree: NIST's Center for AI Standards and Innovation (CAISI) found that new attacks raised agent hijacking success from 11% to 81%. Below are the primary numbers, each with its date, source and limits.

Key AI Agent Security Statistics at a Glance

Each row is a separate finding from a different population. Do not add, average or rank them against each other.

Sources for every row are linked in the sections below and listed under Sources and References. For broader figures on AI adoption, shadow AI and breach costs, see our AI security statistics page. This page covers only agents: AI systems that plan and take actions through tools, memory and permissions.

How to Read AI Agent Security Statistics

Agent security numbers come from five kinds of evidence. They answer different questions, so keep them apart.

Evidence typeExample on this pageWhat it can tell youWhat it cannot tell you
Executive or practitioner surveyMcKinsey, Deloitte, Gartner, Salesforce, SailPoint, PwCWhat respondents say about adoption, policy and incidentsHow often agents are actually compromised
Platform telemetryMicrosoft Cyber PulseHow many organizations run agents on one vendor's platformAnything about other platforms or about security outcomes
Lab evaluation or benchmarkNIST CAISI, AgentDojo, Agent Security Bench, ARTHow often defined attacks succeed against defined agentsThe success rate against your agent, tools and data
Vulnerability record or incident reportNVD entries, Anthropic's campaign reportThat a specific flaw or attack existed, with dates and scoresHow common the flaw is across all deployments
Analyst forecastGartner predictionsA direction that analysts expectSomething that has already happened

Two rules follow. First, a survey percentage and a lab success rate cannot be compared. Second, a forecast should never be quoted as a fact. Where this page compares two numbers, both come from the same survey and the same sample.

AI Agent Adoption Statistics

Adoption figures vary widely because "using AI agents" means different things in each study. Some count pilots, some count production use and some count tools embedded in software the company already owns.

The spread between 23% (McKinsey, scaling) and 79% (PwC, "being adopted") is a definition gap, not a contradiction. For a security plan, the useful question is narrower: how many agents in your environment can act on systems or data without a human approving each step?

AI Agent Governance and Access-Control Statistics

Governance data is where agentic AI security statistics become most useful. The same surveys that show fast adoption also show that controls lag behind.

The adoption-to-governance gap, measured within each survey

The table below is DeepStrike's own calculation. Each row compares two figures from the same survey and the same respondents, which is the only fair way to measure the gap.

SurveyAdoption or planControl in placeGap in percentage points
SailPoint, 353 respondents, 202582% use AI agents44% have policies to secure them38
Deloitte, 3,235 respondents, 202574% expect at least moderate use by 202721% have mature agent governance53
Salesforce, 2,000+ security leaders, 2024 to 202575% expect to use agents within two years45% fully confident in their guardrails (100% minus 55%)30

Microsoft's telemetry figure (more than 80% of the Fortune 500) and its survey figure (47% with generative AI controls) come from different populations, so we do not subtract one from the other.

Bar chart: AI agent adoption vs governance in three surveys, with 38, 53 and 30 point gaps

Across three independent surveys, the share of organizations planning or running agents exceeds the share with mature controls by 30 to 53 points. That is the practical case for testing agent permissions before an incident tests them for you. Our guide to agentic AI security explains how to scope and test agent tools, identities and memory against the OWASP Top 10 for Agentic Applications.

AI Agent Risk Statistics: What Organizations Report

Self-reported incident data for agents is still thin. The most detailed public breakdown comes from SailPoint's 2025 survey. SailPoint sells identity security products and commissioned the research, so treat the figures as indicative rather than representative.

Reported agent behaviorShare of respondents
AI agents have taken unintended actions80%
Agents accessed unauthorized systems or resources39%
Agents downloaded sensitive content32%
Agents accessed or shared sensitive or inappropriate data31% to 33%
Agents were tricked into revealing access credentials23%

Source: SailPoint, AI agents: The new attack surface, May 28, 2025; 353 IT professionals with enterprise security responsibilities on five continents, surveyed by Dimensional Research.

"Unintended action" covers mistakes as well as attacks, and the survey does not say how many events were caused by an adversary. Still, 23% reporting credential disclosure is a signal that agents are already being manipulated in production, not only in labs. Credential handling is also where agents meet tool servers; our MCP security guide covers token passthrough, over-broad OAuth scopes and tool poisoning in detail.

Agent Hijacking and Prompt Injection Statistics

Agent hijacking is a form of indirect prompt injection: an attacker hides instructions in data the agent reads, such as an email, web page or tool output, and the agent follows them. Lab results are the best available evidence of how often this works. If you are new to the mechanism, start with our explainer on prompt injection attacks.

NIST CAISI agent hijacking evaluations

NIST's Center for AI Standards and Innovation (then the US AI Safety Institute) published its agent hijacking evaluation results on January 17, 2025, and updated the post on December 19, 2025. CAISI tested agents built on the upgraded Claude 3.5 Sonnet (released October 2024) in AgentDojo's four simulated environments: Workspace, Travel, Slack and Banking.

CAISI findingBeforeAfter
Attack success with new red-team attacks (Workspace environment, held-out tasks)11% for the strongest baseline attack81% for the strongest new attack
Average success across five injection tasks, one attempt versus 25 attempts57%80%

Three further findings matter for security teams:

DeepStrike's reading: moving from one attempt to 25 attempts raised measured success by 23 percentage points, about 1.4 times the single-attempt rate. A test plan that tries each attack once will understate risk for any agent an attacker can query repeatedly.

NIST CAISI agent hijacking results: 11% to 81% with new attacks, 57% to 80% with 25 attempts

Academic and public benchmarks

BenchmarkPublisher and dateScaleHeadline result
AgentDojoETH Zurich and Invariant Labs, 202497 realistic tasks and 629 security test casesExisting attacks broke some security properties but not all; models also failed many tasks without any attack
Agent Security Bench (ASB)Zhejiang University and Rutgers University, ICLR 202510 scenarios, 10 agents, more than 400 tools, 13 model backbonesHighest average attack success rate of 84.30%, with limited effectiveness from current defenses
Agent Red Teaming (ART) competitionGray Swan AI with the UK AI Security Institute, July 202522 frontier agents, 44 deployment scenarios, 1.8 million prompt-injection attacksOver 60,000 attacks caused policy violations; nearly all agents violated policy for most behaviors within 10 to 100 queries

Sources: AgentDojo on arXiv, Agent Security Bench on arXiv and Security Challenges in AI Agent Deployment on arXiv.

By our calculation, over 60,000 successful attacks out of 1.8 million submitted means at least 3.3% of all competition submissions worked. That low per-attempt rate is not reassuring: the same study found that persistent attackers broke nearly every agent within 10 to 100 queries, and that robustness correlated only weakly with model size, capability or inference-time compute. For adversarial testing methods that account for this, see our guide to AI red teaming.

Real AI Agent Incidents and CVEs

Vulnerability records show that agent flaws are not hypothetical. The entries below are confirmed in the National Vulnerability Database (NVD) or in the operator's own incident report. They are examples, not a complete count.

CaseDateProductWhat happenedSeverity or scale

NVD records: CVE-2025-32711, CVE-2025-54135 and CVE-2025-53773. Campaign details come from Anthropic's disclosure.

Two patterns stand out. The first three cases share a root cause: the agent treated attacker-controlled content as instructions and then used a privileged capability, such as data access, file writes or code execution. The fourth case is the reverse: an agent used as the attacker's tool. Anthropic also notes that the agent sometimes hallucinated credentials or overstated what it had stolen, which still limits fully autonomous attacks. For wider data on attackers using AI, see our AI cyber attack statistics.

Several MCP-specific CVEs from 2025, including flaws in mcp-remote, MCP Inspector and the official filesystem server, are analyzed in our MCP security guide rather than repeated here.

Timeline of AI agent security milestones from Gartner's 2024 forecast to its 2026 agent access survey

The OWASP agentic list is different from the OWASP Top 10 for LLM Applications, which focuses on model-centric risks such as prompt injection and sensitive information disclosure. Our OWASP LLM Top 10 breakdown covers that list. For how these lists fit with NIST AI RMF, MITRE ATLAS and ISO/IEC 42001 across the wider AI attack surface, see our guide to what AI security is.

AI Agent Security Forecasts (Gartner Predictions)

Everything in this section is a forecast. These are analyst predictions, not measured outcomes, and they should be labeled that way whenever they are quoted.

Gartner predictionTarget yearPublished
25% of enterprise breaches will be traced back to AI agent abuse, from both external and malicious internal actors2028October 22, 2024
40% of CIOs will demand "guardian agents" to track, oversee or contain the results of AI agent actions2028October 22, 2024

At least 15% of day-to-day work decisions will be made autonomously through agentic AI, up from 0% in 20242028June 25, 2025
40% of enterprise applications will be integrated with task-specific AI agents, up from less than 5% in 2025End of 2026August 26, 2025
25% of enterprise generative AI applications will experience at least five minor security incidents per year, up from 9% in 20252028April 9, 2026
15% of enterprise generative AI applications will experience at least one major security incident per year, up from 3% in 20252029April 9, 2026

Sources: Gartner's top predictions for 2025 and beyond, the June 2025 agentic AI release linked above, the task-specific agents forecast and the generative AI security incident forecast.

The April 2026 forecast ties the rise directly to agentic applications built on the Model Context Protocol (MCP). Gartner advises treating any use case where an agent can access sensitive data, ingest untrusted content and communicate externally in the same flow as a "no-go zone" because of exfiltration risk. Gartner also notes "agent washing": it estimates that only about 130 of the thousands of vendors claiming agentic AI offer real agentic capabilities.

What These Statistics Mean for Testing AI Agents

The numbers above support a short list of testing decisions. The mapping below is DeepStrike's analysis, not a finding from any single source.

StatisticWhat it suggestsWhat to test
54% have no defined approach to limiting agent access (Gartner, 2026)Agents often inherit broad human or service-account permissionsEnumerate each agent's identities, scopes and reachable data; try to make it act outside its intended role
23% report agents tricked into revealing credentials (SailPoint, 2025)Secrets reach the model's context or tool outputsPlant canary secrets in a test environment and check whether injected content can extract them
57% rose to 80% with 25 attempts (NIST CAISI, 2025)One-shot testing understates riskRepeat each injection scenario many times with variations and report a success rate, not a single pass or fail
New attacks raised success from 11% to 81% (NIST CAISI, 2025)Default benchmark attacks are not enoughInclude adaptive, target-specific attacks written for your agent and tools
EchoLeak and CVE-2025-54135 (NVD, 2025)Untrusted content plus a privileged action equals an exploit pathTrace every path from untrusted input (email, documents, web, repositories) to a sensitive action (send, write, execute)
Gartner "no-go zone" (2026)Sensitive data, untrusted content and outbound communication in one flow is high riskConfirm that no single agent workflow combines all three without a human approval gate

Run these tests in a lab or an explicitly authorized scope with synthetic data. Our agentic AI security guide gives a full test matrix for each OWASP agentic risk.

Methodology and Limitations

We will review this page when Gartner, McKinsey, Deloitte, NIST CAISI or OWASP publish new agent data, and when a new agent CVE rated critical appears in NVD.

Frequently Asked Questions

How secure are AI agents?

Current evidence says not secure enough to trust without controls. In NIST CAISI's 2025 tests, tailored attacks hijacked an agent built on one of the most hijack-resistant models AgentDojo had tested 81% of the time, and in a 2025 public competition with the UK AI Security Institute nearly every agent violated its policies within 10 to 100 attacker queries. Security depends less on the model than on what the agent is allowed to do: its permissions, tools, approval gates and monitoring.

What percentage of companies use AI agents?

It depends on the definition. McKinsey's 2025 survey found 23% of respondents scaling an agentic system and 62% at least experimenting. PwC found 79% of 300 US senior executives saying agents were being adopted. Microsoft telemetry shows more than 80% of Fortune 500 companies running active low-code or no-code agents as of November 2025.

What are the biggest security risks of AI agents?

The OWASP Top 10 for Agentic Applications (December 2025) lists ten, including agent goal hijack, tool misuse, identity and privilege abuse, agentic supply chain vulnerabilities and memory poisoning. Survey data matches this: in SailPoint's 2025 study, 39% reported agents accessing unauthorized systems and 23% reported agents tricked into revealing credentials.

How often does prompt injection succeed against AI agents?

Rates depend on the agent, the task and the attacker's effort. Published results include 81% for tailored attacks in NIST CAISI's tests, an 84.30% highest average attack success rate in Agent Security Bench (ICLR 2025) and at least 3.3% of 1.8 million competition submissions. Repeated attempts raise success: CAISI's average rose from 57% to 80% over 25 tries.

Are there real CVEs for AI agents?

Yes. Examples include EchoLeak (CVE-2025-32711) in Microsoft 365 Copilot, rated 9.3 by Microsoft, CVE-2025-54135 in the Cursor code editor and CVE-2025-53773 in GitHub Copilot and Visual Studio, all published in NVD between June and August 2025.

Will AI agents cause more breaches?

Gartner forecasts that by 2028, 25% of enterprise breaches will be traced back to AI agent abuse, and that 25% of enterprise generative AI applications will have at least five minor security incidents a year, up from 9% in 2025. Both are predictions, not measurements.

Next Step: Test Your Agents Before an Attacker Does

The statistics point to one practical conclusion: most organizations are deploying agents faster than they are constraining them, and single-pass testing understates how often hijacking works. The fix is to measure your own agents: what they can reach, what untrusted content they read and what they can do with it.

DeepStrike's LLM and AI application penetration testing covers prompt injection and jailbreak attack simulation, data leakage and model poisoning, with testing aligned to the OWASP LLM Top 10, the NIST AI Risk Management Framework and MITRE ATLAS, and validated findings with proof of exploitation.
