Penetration Testing Statistics 2026: Breach Costs, Attack Vectors, and Why Testing Pays

The penetration testing and breach statistics that matter in 2026: breach costs, initial attack vectors, ransomware, CVE volume, and market growth, all sourced.

Security budgets get approved with numbers, not adjectives. This page collects the penetration testing and breach statistics that actually move decisions, drawn from the primary industry reports (IBM, Verizon, Cybersecurity Ventures, the CVE program, and the major market analysts), with a source for every figure so you can cite them in a board deck, a budget request, or your own writing. We update it as the annual reports land.

How to cite: link to this page or to the primary source listed beside each figure. Every number below is attributed.

Key numbers at a glance

  • $4.99 million global and $11.5 million in the US: the average data breach cost in 2026. (IBM 2026)
  • 31% of breaches now start with vulnerability exploitation, the top initial access vector. (Verizon 2026 DBIR)
  • 48% of breaches involved ransomware. (Verizon 2026 DBIR)
  • 48,185 CVEs were published in 2025, about 131 a day. (Jerry Gamblin)
  • $2 to 3 billion: the penetration testing market, growing 12 to 20% a year across four analyst estimates. (See section 6.)

1. What a breach costs

  • $4.99 million: the global average cost of a data breach in 2026, a record and up 12% in a year. (IBM Cost of a Data Breach Report 2026, 602 organizations)
  • $11.5 million: the average cost of a breach for US organizations, more than double the global figure and the most expensive of any country. (IBM 2026)
  • 247 days: the mean time to identify and contain a breach (183 to identify, 64 to contain), up 2.5% year over year. (IBM 2026)

What this means for testing: the US number is the one that matters for a New York company, and it is a record. Against an $11.5 million average, a fixed-price penetration test is a rounding error. Our pricing page shows what one costs.

2. How attackers actually get in

From Verizon’s 2026 Data Breach Investigations Report, which analyzed more than 31,000 security incidents including 22,000 confirmed breaches:

  • 31% of breaches began with the exploitation of a vulnerability, the first time in the DBIR’s history that it beat stolen credentials as the top initial access vector. (Verizon 2026 DBIR)
  • 13% of breaches began with credential abuse as the initial vector, down from 22% the year before, though credentials still appeared somewhere in 39% of breaches. (Verizon 2026 DBIR)
  • 48% of breaches involved a third party, a 60% increase in one year. (Verizon 2026 DBIR)

What this means for testing: the leading initial access vectors, exploitable vulnerabilities and stolen credentials, are precisely what an external network test and a phishing and social engineering assessment measure. The third-party figure is why enterprise customers now send security questionnaires to every vendor, and why a current penetration test report has become a sales document as much as a security one.

3. Ransomware

  • 48% of breaches in the 2026 DBIR involved ransomware, up from 44% the year before. (Verizon 2026 DBIR)
  • $57 billion: projected global ransomware damage costs in 2025, which works out to roughly $156 million per day. (Cybersecurity Ventures)
  • $275 billion: projected annual ransomware damage by 2031, with an attack every two seconds. (Cybersecurity Ventures)

What this means for testing: ransomware operators get in through the same doors as everyone else (credentials, exposed services, unpatched perimeter devices) and then spread laterally. The spread is what an internal network penetration test measures, and flat networks with weak Active Directory hygiene are where a single compromised laptop becomes a company-wide event. Our guide to how ransomware attacks work traces the full chain.

4. The vulnerability firehose

  • 48,185 CVEs were published in 2025, a 20.6% increase over 2024 and the highest annual total on record, roughly 131 new vulnerability disclosures every day. (Jerry Gamblin, 2025 CVE Data Review; The Stack)
  • Counting methods vary by source; an alternative tally puts 2025 at 46,407 CVEs, up 16% from 40,009 in 2024, or about 127 per day. Either way, 2025 set a record. (Socket; DeepStrike)
  • Only 26% of known exploited vulnerabilities were fully remediated during 2025, down from 38%, and the median time to full remediation rose from 32 to 43 days. (Verizon 2026 DBIR)

What this means for testing: at more than a hundred new disclosures a day, an annual point-in-time test describes a system that no longer exists by the time the report is filed. This is the arithmetic behind continuous penetration testing and validated vulnerability scanning between manual tests, the model our penetration testing as a service program is built on. The vulnerability count is also why “we patch monthly” is not a security posture; the DBIR’s 31% exploitation figure is what happens in the gap.

5. The size of cybercrime

6. The penetration testing market

The analyst firms disagree on the exact size, which is itself worth knowing before you quote one number as fact. The range for 2025:

The consistent story across all four: a $2 to 3 billion market growing 12 to 20% a year, with North America the largest region. The growth is compliance-driven (SOC 2, PCI DSS, HIPAA, NYDFS 500, and CMMC all expect testing) and customer-driven (the third-party breach share above).

7. What the numbers add up to

Put the primary sources side by side and a clear picture emerges:

  1. Breaches are expensive and, in the US, at a record ($11.5 million average).
  2. Attackers arrive through exploitable vulnerabilities and credentials (vulnerability exploitation now starts 31% of breaches, and credentials appear in 39%), the two things penetration testing directly measures.
  3. Ransomware is in nearly half of breaches (48%), and it spreads through internal networks that were never tested from the inside.
  4. New vulnerabilities appear faster than annual testing can track (131 a day), which argues for continuous coverage.
  5. Your customers’ breaches are increasingly your problem (48% third-party involvement), which is why they now demand your test report.

The practical conclusion is not “test more.” It is: test the external perimeter and credentials at least annually, test the internal network before ransomware does, and if you ship software weekly, move to a cadence that matches. Every one of those engagements has a fixed price at Invadel, and every one includes a free retest.

Frequently asked questions

How often is this page updated? When the primary annual reports publish: IBM’s Cost of a Data Breach (typically mid-year), Verizon’s DBIR (typically spring), and the CVE program’s year-end totals. Check the source links for the newest edition.

Why do the market-size figures differ so much? Each analyst defines the market differently (some include automated scanning platforms, some only services) and uses different survey bases. Quote a range, or name the firm whose definition matches your use.

Which single statistic should I use in a budget request? For a US company, the $11.5 million average breach cost from IBM 2026, alongside the DBIR’s 31% of breaches starting from an exploitable vulnerability. Together they say: the thing a penetration test finds is now the single most common way breaches start, and a breach costs eight figures.

Can I reuse these statistics? Yes. Cite the primary source listed with each figure, and feel free to link this page as the compilation.
