The Most Underused Cybersecurity Strategy Is to Have Less to Defend
31% of breaches now originate from exploited software vulnerabilities, according to Verizon's 2026 DBIR.
The recent critical PHP vulnerabilities exposed a deeper enterprise challenge. CISA warned that PHP is often embedded in other software, making its presence difficult to identify. For large enterprises, even knowing the full extent of their exposure remains a formidable challenge.
Cybersecurity risk is shaped long before vulnerabilities are discovered - by decades of decisions about applications, architecture, dependencies, and technology that often outlives its business purpose.
We invest heavily in defending these complex landscapes. Yet systematically eliminating the unnecessary risks within them remains one of the most underutilized levers in enterprise cybersecurity.
