Penetration Testing Report Reveals Alarming Growth in Enterprise Attack Surfaces

A comprehensive analysis of over 4,200 global penetration testing assessments across enterprise environments reveals organizations are struggling to keep pace with expanding attack surfaces, particularly as AI and automated coding accelerate software deployment cycles. The BreachLock 2025 Penetration Testing Intelligence Report highlights critical security gaps across multiple industries.

"Cybersecurity is no longer about reacting to yesterday's threats. It's about preparing for tomorrow's," states Seemant Sehgal, Founder & CEO of BreachLock.

Critical Vulnerabilities Dominate Findings

The report reveals that 45% of all findings were rated Critical or High severity. Organizations implementing comprehensive vulnerability assessment programs discovered significant security issues including:

• Broken access control affecting 32% of high-severity findings
• Security misconfigurations present in 52% of tested systems
• Persistent injection attacks in legacy applications and APIs

Most concerning, red team simulations achieved lateral movement within just 2.5 hours, demonstrating how quickly attackers can compromise systems.

AI and Machine Learning Present New Challenges

For the first time, the report included large language model (LLM) security testing results. Key vulnerabilities in AI systems include prompt injection attacks, data leakage, and model poisoning.

"While LLMs are getting better at generating syntactically correct and functional code, their ability to produce secure code has not shown meaningful improvement," explains Mike McGuire, Senior Security Solutions Manager at Black Duck.

Industry-Specific Impacts and Recommendations

Different sectors face unique challenges in their enterprise cybersecurity strategy implementation:

• Technology & SaaS providers experienced a 400% year-over-year increase in critical API vulnerabilities
• Healthcare organizations struggle with broken access control (22%) and security misconfiguration (17%)
• Retail sector saw 68% of APIs with misconfigured authorizations

The report recommends several strategic imperatives for organizations:

1. Implement continuous security validation beyond periodic testing
2. Prioritize API and identity security measures
3. Integrate security early in the development process
4. Use MITRE ATT&CK framework for threat prioritization
5. Conduct dedicated testing for AI systems

Organizations should evaluate their security testing frequency and coverage, review API security measures against industry benchmarks, and assess AI deployment security controls. The findings underscore the critical need for organizations to adopt more proactive and continuous security validation approaches as attack surfaces continue to expand.
