Why Most Microsegmentation Projects Fail—And How Andelyn Biosciences Got It Right

Why Most Microsegmentation Projects Fail—And How Andelyn Biosciences Got It Right

Mar 14, 2025 Zero Trust / Network Security
Most microsegmentation projects fail before they even get off the ground—too complex, too slow, too disruptive. But Andelyn Biosciences proved it doesn't have to be that way.  Microsegmentation: The Missing Piece in Zero Trust Security   Security teams today are under constant pressure to defend against increasingly sophisticated cyber threats. Perimeter-based defenses alone can no longer provide sufficient protection as attackers shift their focus to lateral movement within enterprise networks. With over 70% of successful breaches involving attackers moving laterally, organizations are rethinking how they secure internal traffic.  Microsegmentation has emerged as a key strategy in achieving Zero Trust security by restricting access to critical assets based on identity rather than network location. However, traditional microsegmentation approaches—often involving VLAN reconfigurations, agent deployments, or complex firewall rules—tend to be slow, operationally disrupt...
