Use Case 1: Preventing Lateral Movement in Hybrid & Multi-Cloud Environments
Introduction
Organizations operating in hybrid and multi-cloud environments face significant security challenges. Traditional network security cannot effectively stop lateral movement once an attacker gains access. Attackers use compromised cloud workloads or on-premise resources to move laterally, searching for sensitive data and privileged accounts. Microsegmentation ensures that every workload is isolated, preventing unauthorized access and stopping attackers from moving freely across environments.
Problem Statement
- Cloud & Hybrid Environments Increase Attack Surfaces: Organizations use multi-cloud platforms (AWS, Azure, Google Cloud) and on-premises data centers, making it hard to enforce consistent security policies.
- Lack of Granular Security Controls for Workloads: Traditional firewalls and VLAN-based segmentation lack visibility into east-west traffic, allowing attackers to move undetected.
- Difficulties Enforcing Zero Trust Across Distributed Environments: Legacy segmentation relies on static IP addresses, which do not adapt to dynamic cloud workloads and identity-based security models.
Solution: TerraZone Microsegmentation
TerraZone prevents lateral movement in hybrid and multi-cloud networks by enforcing identity-based segmentation policies, limiting access between workloads, and ensuring continuous visibility into east-west traffic.
- Identity-Based Segmentation for Cloud & On-Prem Resources – Restricts communication between workloads based on identity, role, and risk level, ensuring least-privilege access.
- Dynamic Security Policies for Cloud Workloads – Adapts security policies dynamically as workloads scale up or down, ensuring consistent segmentation across environments.
- Real-Time Traffic Monitoring & Threat Detection – Continuously inspects network traffic patterns to detect unauthorized connections and policy violations.
- Seamless Hybrid & Multi-Cloud Security – Ensures consistent segmentation policies across AWS, Azure, Google Cloud, and on-premise data centers.
- Zero Trust Network Enforcement – Verifies and validates every connection request before granting access, preventing unauthorized communication.

Use Case 2: Preventing Ransomware Spread with Microsegmentation
Introduction
Ransomware attacks continue to evolve, leveraging compromised endpoints to spread across networks. Once inside, attackers use lateral movement techniques to encrypt data, exfiltrate information, and disrupt operations. Traditional security tools fail to contain ransomware once it has breached a perimeter defense.
Problem Statement
- Ransomware Uses Lateral Movement to Target Critical Systems: Attackers compromise a single endpoint and then spread across file shares, databases, and infrastructure.
- Firewalls & Antivirus Alone Cannot Contain Attacks: Traditional endpoint security solutions react after malware is executed, leaving gaps for fast-spreading ransomware.
- Lack of Granular Access Control on Critical Systems: Organizations fail to restrict access between endpoints, file servers, and sensitive applications, allowing ransomware to encrypt critical data.

Use Case 3: Protecting Financial Services from Advanced Threats & Compliance Violations
Introduction
Financial institutions handle high-value transactions, sensitive customer data, and regulatory compliance requirements. However, traditional network security models cannot prevent attackers from moving laterally once they gain access. If a single banking application, employee endpoint, or third-party system is compromised, attackers can move across the network, accessing payment systems, customer records, and critical infrastructure. Microsegmentation ensures every transaction, system, and user interaction is secured, preventing unauthorized access and containing potential breaches.
Problem Statement
- Financial Data is a Prime Target for Cybercriminals: Attackers exploit unsecured internal communications to access payment processing systems, customer databases, and trading platforms.
- Regulatory Compliance Requires Strict Data Segmentation: Financial institutions must comply with PCI-DSS, GDPR, SOX, and banking security mandates, requiring strict isolation of customer and transaction data.
- Third-Party Vendors Introduce Supply Chain Risks: Many financial services rely on third-party integrations that, if compromised, can introduce vulnerabilities into core banking infrastructure.
