Why Legacy Infrastructure Is Your Biggest Cybersecurity Blind Spot

Insights from RedRok’s latest webinar: Master Your Internal Infrastructure with with RedRok’s co-founders: Alon Kogan & Nitzan Levi 

Most organizations are investing heavily in AI, cloud migration, and digital transformation yet a critical security problem persists quietly underneath. In RedRok’s recent live webinar, co-founder Nitzan Levi laid out a hard truth: the biggest barrier to modern cybersecurity isn’t a lack of tools or budget. It’s the complex and living infrastructure that organizations have been quietly accumulating for decades.

The problem nobody wants to talk about

Modern enterprises rarely start with a clean slate. They operate hybrid environments clouds layered on top of on-prem systems layered on top of technologies that predate the modern threat landscape. Active Directory, introduced in 1999, still anchors identity management across many organizations today. Over the years, these environments quietly accumulate:

  • Hidden configurations
  • Excessive privileges
  • Misconfigured access policies
  • Legacy services
  • Unmanaged shared resources
  • Technical debt

The result is an environment that becomes increasingly difficult to monitor and secure, especially as organizations onboard new SaaS tools, AI agents, and cloud platforms at speed.

Attackers don’t need domain admin

One of the webinars’ most striking takeaways: attackers no longer need full administrative access to do serious damage. Modern threat actors simply follow the path of least resistance exploiting misconfigurations, weak permissions, shared credentials, forgotten internal shares, and shadow admins that accumulate quietly over time.

“The challenge is not just finding vulnerabilities – it’s understanding the actual attack path an adversary could take.”  Nitzan Levi, RedRok co-founder

Cyber hygiene over perfection

RedRok’s approach isn’t about boiling the ocean. Most organizations can’t redesign or replace legacy systems overnight, and they shouldn’t have to. Instead, Nitzan advocates for a practical strategy built around cyber hygiene: gain visibility into the environment, understand attack paths, reduce exposure where possible, and block attackers at critical chokepoints.

The goal isn’t a perfect security posture. It’s a pragmatic, continuously improving one.

The new challenge: shadow AI

Beyond legacy infrastructure, the webinar surfaced a fast-moving new risk: shadow AI. Employees across organizations are rapidly installing and experimenting with AI-powered tools often without any IT or security oversight. These tools can introduce unauthorized integrations, excessive permissions, sensitive data exposure, and entirely new attack surfaces before anyone in security is aware they exist.

Visibility into which AI services are running inside your environment isn’t optional anymore; it’s foundational.

Visibility is where security starts

RedRok’s internal scanning platform is purpose-built for this challenge. It helps security teams discover shadow admins, exposed certificates, misconfigured policies, AI tools, vulnerable services, and data leakage risks all without requiring intrusive deployment changes, firewall modifications, or elevated permissions.

Security is a continuous journey, not a one-time project. The organizations that come ahead will be the ones that build ongoing visibility and assessment into how they operate, not just how they respond.
