Why is microsegmentation essential for Zero Trust?

Zero Trust requires strict control of all access paths. Microsegmentation prevents unauthorized internal movement, even when one server is compromised, making it a core Zero Trust enforcement layer.

How does DBSAFER OS contribute to microsegmentation?

DBSAFER OS monitors and controls operating system actions, enforces command-level policies, and provides visibility into user sessions, ensuring strict control of privileged operations.

Q: What is microsegmentation in cybersecurity?

Microsegmentation is a security approach that isolates workloads, servers, and applications to block lateral movement inside an organization. It enforces least-privilege access and limits server-to-server communication.

Q: How does PNPSECURE implement microsegmentation?

PNPSECURE uses a Server Agent to control inter-server communication and DBSAFER OS to enforce granular user and command-level control. Together they create a secure segmentation boundary across servers and workloads.

Q: What does the Server Agent do?

The Server Agent enforces least-privilege communication between servers by analyzing traffic and blocking unauthorized connections, preventing lateral movement after credential compromise.

What is microsegmentation in cybersecurity?

Microsegmentation is a security strategy that isolates workloads, servers, and applications to prevent unauthorized lateral movement inside an organization. It blocks unnecessary server-to-server communication and enforces least-privilege access at a granular level to stop attackers from spreading after an initial breach.

Why is microsegmentation essential for modern Zero Trust environments?

Attackers increasingly exploit internal movement after compromising one system. Zero Trust assumes no implicit trust—even within the internal network. Microsegmentation strengthens Zero Trust by applying strict, identity-based control between servers and preventing internal threat propagation.

How does PNPSECURE implement microsegmentation?

PNPSECURE provides microsegmentation through two core components:
(1) Server Agent for server-to-server communication control,
(2) DBSAFER OS for granular, command-level operating system control.
Together, they create a complete segmentation boundary that blocks unauthorized access between systems.

What does the Server Agent do?

The Server Agent analyzes inter-server traffic and enforces minimal communication permissions. It prevents unauthorized server-to-server access, eliminates unnecessary internal ports and processes, and stops attackers from moving laterally inside the network—especially after admin credential theft.

How does DBSAFER OS enhance microsegmentation?

DBSAFER OS enforces granular control at the OS level. It monitors and restricts user actions, applies command-level policies, logs all operations, and enables real-time session monitoring. Even if a user gains valid system access, DBSAFER OS ensures their actions remain strictly controlled.

How does microsegmentation help prevent APT and internal attacks?

Because every server, task, and identity is controlled individually, attackers cannot move laterally or escalate across the environment. Even if a single server is breached, microsegmentation confines the attack and prevents further compromise—effectively neutralizing APTs at the source.

Why is microsegmentation considered a core Zero Trust requirement?

Zero Trust requires both continuous verification and strict segmentation. Microsegmentation enforces the principle of “never trust, always verify” not only at login but across all network paths and workloads. It turns Zero Trust from a concept into a real, enforced security architecture.
