Unpatched vulnerabilities remain a significant vector for cyberattacks, with numerous studies highlighting their role in data breaches and ransomware incidents. 

Key Statistics:

60% of Data Breaches: A 2019 Ponemon Institute survey found that 60% of data breaches were caused by known vulnerabilities that had available patches but were not applied.

20% of Breaches in 2025: The 2025 Data Breach Investigations Report (DBIR) indicated that 20% of breaches involved exploitation of vulnerabilities, with many being unpatched.

32% of Ransomware Attacks: According to Sophos' 2024 State of Ransomware report, 32% of ransomware attacks originated from unpatched vulnerabilities.

These statistics underscore the critical importance of timely patch management in preventing cyberattacks.

For instance, the 2023 MOVEit data breach exploited an unpatched vulnerability in the MOVEit software, affecting over 2,700 organizations.

To mitigate such risks, organizations should implement regular patching schedules, prioritize critical vulnerabilities, and consider automated patch management solutions.
