Fast Facts
- Nearly all security leaders (99%) plan or implement microsegmentation, yet over 90% protect less than 80% of critical systems, highlighting a significant coverage gap.
- Despite ranking microsegmentation as a top initiative to prevent lateral attacks, 44% lack comprehensive device visibility and only 24% have deployed microsegmentation as part of zero trust.
- Modern, identity-based microsegmentation offers rapid containment of threats without agents or hardware changes, contrasting with outdated network-location based approaches.
- Healthcare and manufacturing sectors face specific challenges, such as integration with clinical staff devices and legacy OT systems, but organizations are increasingly adopting modern solutions for enhanced security.
Key Challenge
A recent Omdia survey, commissioned by Elisity, reveals a significant gap between the desire for microsegmentation and its actual implementation in U.S. healthcare and manufacturing organizations. Nearly all cybersecurity leaders acknowledge the importance of deploying microsegmentation, with 99% actively working toward it. However, less than 10% report that over 80% of their critical systems are protected, leaving the majority with limited coverage. This shortfall is troubling because, despite ranking microsegmentation as the top strategy against lateral movement attacks, about half of these leaders experienced such breaches in the past year. The root causes include gaps in device visibility, reliance on outdated network security methods like VLANs and ACLs, and limited familiarity with modern, identity-based microsegmentation solutions, which are easier to deploy and more effective. Business pressures, such as cyber insurance requirements and regulatory standards, are driving adoption, yet many organizations still depend on legacy tools that leave their internal networks vulnerable. Experts from the industry emphasize that modern microsegmentation, which enforces policies directly on network switches without complex reconfigurations, can better contain cyber threats and streamline security efforts. Overall, the data underscores a pressing need for organizations to transition from traditional approaches to more effective, identity-based microsegmentation strategies to protect against prevalent threats and meet evolving security demands.
Security Implications
If your business relies on microsegmentation to protect sensitive systems, a recent survey reveals a pressing concern: while 99% of organizations claim to back microsegmentation, over 90% fall short in actually safeguarding their critical systems. This gap means that, despite believing they are secure, many companies remain vulnerable to cyberattacks that can compromise sensitive data, disrupt operations, and cause costly downtime. Consequently, the false sense of security can lead to severe financial losses, reputational damage, and legal liabilities. In short, without effective implementation, microsegmentation alone is insufficient—weaknesses in the security approach can leave your business exposed, no matter your industry. Therefore, it’s vital to evaluate and strengthen your defenses continuously to truly protect your most valuable assets.
Fix & Mitigation
Prompt response to vulnerabilities is crucial to maintaining organizational security and preventing malicious attacks, especially when survey data reveals a significant gap between the adoption of microsegmentation and its effective implementation for critical systems.
