Network segmentation and firewall security
Modern Workspace > Network segmentation and firewall security
Flat networks create broad opportunities for attackers to move laterally after a breach. Strategic network segmentation and next-generation firewalls (NGFWs) allow you to isolate workloads, enforce least-privilege access, and reduce blast radius in the event of a compromise.
Allevio helps organizations design, implement, and manage secure network architectures with granular segmentation and robust firewall control. Whether modernizing legacy networks, deploying hybrid firewalls, or adopting a Zero Trust model, we help you build the right boundaries in the right places.
What We Offer
Network Architecture Review & Segmentation Design
Build a structured, risk-based network layout:
- Logical and physical segmentation by user, device, application, and sensitivity
- Microsegmentation strategies for internal data centers and cloud workloads
- VLAN planning, subnetting, and route control
- Zero Trust segmentation alignment using identity and context
Firewall Strategy & Implementation
Protect network perimeters and internal zones with next-gen firewalls:
- Design and deployment of NGFWs (on-premises, virtual, and cloud-native)
- Stateful inspection, deep packet inspection, and Layer 7 control
- Intrusion prevention, URL filtering, DNS security, and application control
- Centralized policy management across hybrid environments
Cloud & Hybrid Network Integration
Extend segmentation and firewall controls across environments:
- Cloud-native firewalls and security groups (Azure NSGs/ASGs, AWS SGs/NACLs)
- Hub-and-spoke and transit gateway architectures
- Integration with SD-WAN, SASE, and cloud access edge models
- Policy enforcement across hybrid workloads, remote users, and branches
Monitoring, Auditing & Optimization
Ensure visibility and continuous protection:
- Firewall rule audits and cleanup
- Logging and alert integration with SIEM and SOAR platforms
- Traffic flow analysis and rule tuning
- Regulatory reporting (PCI-DSS, ISO 27001, HIPAA, NIS2)
Technologies & Platforms We Support
