Expert View: Why Microsegmentation Projects Fail

Microsegmentation promises enhanced cybersecurity by limiting lateral movement and enforcing the principle of least privilege. However, many projects falter due to overlooked complexity. This Expert View explains why success hinges on treating microsegmentation as a continuous operational model, not a one-time fix.

Key reasons for failure

  • Lack of application context
  • Ambiguous ownership
  • Insufficient telemetry
  • Overscoping and fragile policies

Success strategies

  1. Start small with well-mapped applications.
  2. Use identity-based policies and integrate with CI/CD.
  3. Ensure rollback and observability.
  4. Time-box exceptions and automate reviews.

Microsegmentation must evolve with infrastructure and culture. Done right, it boosts resilience and delivery speed.
