Cybersecurity Statistics (2026): The Numbers That Matter
A board member asks for “the cybersecurity number” to support next quarter's budget. There are plenty to choose from: breach cost, ransomware activity, vulnerability exploitation, attacker speed, AI-enabled attacks, or workforce shortages.
The problem is that those numbers measure different things.
Cybersecurity statistics in 2026 show that breach costs are rising, attackers are exploiting vulnerabilities faster, ransomware remains widespread even as payments fall, and AI is changing both attacks and defenses.
The useful way to read these figures is not as one global cybersecurity score. Keep the population, period, and evidence type attached to each statistic and look for trends that appear across multiple datasets.
Key cybersecurity statistics in 2026
$4.99 million:IBM's 2026 global average cost of a data breach, up 12% from the previous report. The study covered 602 organizations breached between March 2025 and February 2026
$6 million: Average cost of an AI-enabled malicious breach in IBM's 2026 research, roughly $1 million above the overall global average. One in four malicious breaches in the study was AI-enabled.
29 minutes: CrowdStrike's average eCrime breakout time during 2025. Its fastest observed breakout took
27 seconds.
More than $820 million: On-chain ransomware payments received during 2025, down approximately 8% from Chainalysis's updated 2024 estimate of $892 million.
48%: Share of breaches involving ransomware in Verizon's 2026 DBIR.
31%: Share of known initial-access vectors involving vulnerability exploitation in the 2026 DBIR, making it the leading initial-access vector in that dataset.
43 days: Median time to fully resolve a critical vulnerability in Verizon's DBIR vulnerability-management data, up from 32 days the previous year.
26%: Share of CISA Known Exploited Vulnerabilities in the DBIR dataset that organizations fully remediated, down from 38% previously.
32%: Share of ransomware attacks attributed to exploited vulnerabilities by respondents to Sophos's 2025 survey of 3,400 affected organizations across 17 countries.
4,875 incidents: Incident corpus analyzed in ENISA's EU Threat Landscape 2025, covering July 2024 through June 2025.
88%: Share of ISC2's 16,029 cybersecurity professionals who reported at least one significant cybersecurity consequence associated with a skills shortage.
94%: Share of respondents to the World Economic Forum's 2026 outlook who expect AI to be the most significant driver of cybersecurity change in 2026.
These numbers describe different layers of cyber risk. Breach-cost studies measure financial impact. Threat providers observe activity within their telemetry. Surveys record respondents' experiences. Blockchain analysis tracks identifiable on-chain payments.
They should not be treated as interchangeable global rates.

What the numbers say when you track direction
One of the clearest changes since the previous version of this article is breach cost.
IBM's 2025 report put the global average cost at $4.44 million. Its 2026 study raises that figure to a record $4.99 million, a 12% year-over-year increase. IBM says the latest research covered 602 organizations affected by breaches from March 2025 through February 2026.
Ransomware moves differently.
Chainalysis measured more than $820 million in on-chain ransomware payments during 2025, approximately 8% below its updated 2024 estimate. Yet the claimed ransomware-victim data cited by Chainalysis increased 50% year over year.
Chainalysis also estimated that the share of victims paying a ransom may have fallen to 28%, while the median payment among observed payments rose 368%, from $12,738 in 2024 to $59,556 in 2025.
That is why “ransomware is increasing” and “ransomware payments are decreasing” can both be true depending on what is being measured.
The strongest signal across several datasets is different: vulnerability exploitation and remediation are becoming increasingly time-sensitive.
Breach cost and attacker speed
IBM's latest study puts the global average breach cost at $4.99 million.
AI is increasingly part of that cost picture. IBM says one in four malicious breaches was AI-enabled, a 56% increase from the prior report, and those breaches cost an average of approximately $6 million.
At the same time, organizations reporting extensive use of AI and automation in security operations saved an average of approximately $1.93 million per breach compared with organizations using none.
These are associations within IBM's study. They should not be read as a guarantee that deploying AI security software automatically reduces a particular organization's breach cost by the same amount.
CrowdStrike provides another view: speed.
Its 2026 Global Threat Report put the average eCrime breakout time at 29 minutes during 2025, with the fastest observed case reaching lateral movement in only 27 seconds. CrowdStrike also reported an 89% increase in attacks by AI-enabled adversaries.
Its August 2026 Threat Hunting Report makes the vulnerability window even clearer. During the first half of 2026, CrowdStrike says 88% of the exploitation it observed involving vulnerabilities with a public proof of concept occurred within 48 hours of the PoC being released.
For software teams, the practical issue is not only finding a vulnerability. It is shortening the distance between discovery, remediation, retesting, and deployment.
That is where security checks need to connect with the broader QA automation strategy rather than becoming a separate process that starts after a release.
Ransomware statistics
Ransomware statistics frequently appear contradictory because different reports count different things.
Chainalysis measures identifiable cryptocurrency activity. Sophos surveys organizations that experienced ransomware. Verizon analyzes breach and incident data contributed by a large network of participating organizations.
In Sophos's 2025 ransomware survey, 32% of affected organizations identified exploited vulnerabilities as the root cause, making vulnerability exploitation the leading reported root cause for the third consecutive year.
Verizon's much broader 2026 breach dataset found ransomware present in 48% of all analyzed breaches, up from the previous report.
Meanwhile, Chainalysis found aggregate on-chain ransomware payments down approximately 8% despite a 50% increase in claimed victims.
Those findings do not cancel each other out.
They suggest that attack volume, successful compromise, payment probability, and payment size are moving independently.
The planning lesson is therefore broader than whether victims pay. Vulnerability remediation, identity protection, backups, incident response, recovery, and verification each need their own controls.
Vulnerability exploitation is the converging signal
The strongest overlap across the major 2026 reports is vulnerability exploitation.
Verizon's 2026 DBIR analyzed more than 31,000 security incidents and 22,000 confirmed breaches across 145 countries. Vulnerability exploitation became the most common known initial-access vector, accounting for 31%, while credential abuse fell to 13%.
At the same time:
only 26% of CISA KEVs in Verizon's vulnerability-management dataset were fully remediated;
median full-resolution time increased from 32 to 43 days
organizations had roughly 50% more critical vulnerabilities to address
than in the prior dataset.
Rapid7's 2026 threat research points in the same direction from a different dataset.
It reported a 105% year-over-year increase in confirmed exploitation among newly disclosed CVSS 7–10 vulnerabilities, rising from 71 vulnerabilities in 2024 to 146 in 2025. Median time from publication to inclusion in CISA's KEV catalog fell from 8.5 days to five days.
CrowdStrike adds an important clarification to the earlier draft. Its 2026 report describes a 42% year-over-year increase in zero-day vulnerabilities exploited before public disclosure. That is not the same as saying 42% of all vulnerabilities were exploited before disclosure.
Different providers see different populations, but the direction is consistent: exposure can become operational risk quickly.
AI, workforce, and geopolitics
AI now appears in cybersecurity statistics from both sides of the attack.
IBM's 2026 research found one in four malicious breaches was AI-enabled, with deepfake impersonation and AI-enabled malware among the major categories. More than 20% of studied organizations also reported a breach targeting AI models or applications.
CrowdStrike separately reported an 89% year-over-year increase in activity by AI-enabled adversaries during 2025. That figure represents CrowdStrike's visibility and should not be generalized into a worldwide attacker adoption rate.
Executive expectations point in the same direction.
The World Economic Forum's Global Cybersecurity Outlook 2026 found that:
94% of respondents expect AI to be the most significant driver of cybersecurity change in 2026;
87% identified AI-related vulnerabilities as the fastest-growing cyber risk during 2025;
the share of organizations assessing the security of their AI tools increased from
37% to 64%
The workforce has to absorb those changes.
ISC2's 2025 survey of 16,029 cybersecurity practitioners and decision-makers found that 88% had experienced at least one significant cybersecurity consequence related to a skills shortage.
AI was the most frequently cited skill need at 41%, followed by cloud security at 36%. Seventy-two percent agreed that reducing security personnel significantly increases breach risk in their organizations.
If AI-assisted development is expanding inside your organization, security review needs to grow with it. The same principle applies to vibe coding and AI-generated software: faster code generation does not remove the need for validation before release.
The European threat landscape
ENISA's Threat Landscape 2025 provides a useful regional view, but its numbers should remain explicitly European.
Across 4,875 incidents from July 2024 through June 2025, phishing was the leading intrusion-access method at approximately 60%, followed by vulnerability exploitation at 21.3%.
DDoS accounted for 77% of reported incidents, while hacktivism represented almost 80% of the incident corpus.
But incident count and impact were very different: ENISA says only 2% of hacktivism incidents resulted in service disruption.
Public administration was the most targeted sector at 38.2%, and 53.7% of incidents concerned entities defined as essential under the NIS2 Directive.
That distinction matters.
A category can dominate incident volume without producing the greatest business impact. Security priorities should therefore consider severity, exposure, and operational consequence rather than attack count alone.
How to use cybersecurity statistics without misquoting them
Every cybersecurity number should keep five pieces of context attached:
Metric:
What was actually measured?
Population:
Which organizations, incidents, users, or systems were included?
Period:
When did the events occur?
Source:
Who collected the data?
Evidence type:
Is it a study, survey, telemetry dataset, blockchain analysis, or incident corpus?
For example, Chainalysis's ransomware-payment total is an on-chain measurement.
CrowdStrike's breakout time is provider telemetry.
ISC2's workforce numbers are survey responses.
IBM's breach-cost figures are study estimates based on organizations that experienced breaches.
Verizon's DBIR aggregates real-world incidents and confirmed breaches contributed by participating organizations.
Two percentages can look comparable while answering completely different questions.
Preserving that context is what makes cybersecurity statistics useful enough to cite.
Methodology and sources
This report prioritizes source owners and primary research wherever practical.
The main datasets include:
IBM Cost of a Data Breach Report 2026
Verizon 2026 Data Breach Investigations Report
CrowdStrike 2026 Global Threat Report
CrowdStrike 2026 Threat Hunting Report
Chainalysis 2026 Crypto Crime research
Sophos State of Ransomware 2025
Rapid7 Global Threat Landscape Report 2026
ENISA Threat Landscape 2025
ISC2 Cybersecurity Workforce Study 2025
World Economic Forum Global Cybersecurity Outlook 2026
The observation periods differ between reports. A report published in 2026 may primarily describe activity from 2025, while some sources now include data from the first half of 2026.
For that reason, the statistics should not be added together, averaged, or treated as one global cybersecurity dataset.
Conclusion
The cybersecurity statistics that matter most in 2026 point to a growing problem with time.
IBM's latest study puts average breach cost at a record $4.99 million. Verizon shows vulnerability exploitation becoming the leading initial-access vector while remediation slows. CrowdStrike and Rapid7 show how quickly exploitable weaknesses can move from disclosure toward active use. Meanwhile, ransomware remains widespread even as measured payments decline.
The lesson is not that every cybersecurity metric is moving upward.
It is that organizations have less room for slow detection, delayed remediation, and unverified fixes.
Keep the source, population, observation period, and evidence type attached to every statistic you cite. Then apply the same discipline internally: find weaknesses earlier, repair them faster, and prove the fix before the next release.
