Managed Firewall Operations & Network Perimeter Protection

Service Overview
Comprehensive firewall management services that ensure network perimeter and segmentation controls are correctly designed, consistently enforced, and continuously tuned to block threats while enabling business traffic.

Core Services

  • Policy design & segmentation: network zoning, micro‑segmentation guidance, and least‑privilege traffic flows.
  • Rulebase lifecycle management: rule authoring, cleanup, risk justification, change control, and automation for large rule sets.
  • Device deployment & hardening: secure baseline configurations, OS/firmware management, and vendor‑specific hardening (Cisco, Palo Alto, Fortinet, Check Point, Juniper, cloud NGFWs).
  • Continuous monitoring & health checks: availability, configuration drift detection, capacity planning, and performance tuning.
  • Threat prevention integration: IPS/IDS tuning, URL filtering, application control, SSL/TLS inspection strategy, and malware/ATP integration.
  • Log collection & alerting: centralized logging, retention policies, log parsing for SIEM, and alert thresholds for suspicious flows or policy violations.
  • Change control & compliance: documented change procedures, approval workflows, audit trails, and evidence packages for auditors.
  • Rule optimization & risk reduction: orphaned rule cleanup, hit‑count analysis, rule consolidation, and risk scoring.
  • Emergency support & rapid containment: 24/7 change capability for containment actions, temporary rule pushes, and rollback procedures.
  • Cloud & Hybrid Network Support: cloud-native firewall management (AWS/NACL/SGs, Azure Firewall, GCP), transit/peering controls, and hybrid connectivity security.
  • Automation & Policy-as-Code: IaC for network policies, automated validation, CI/CD for firewall configs, and drift remediation.
  • Training & Documentation: runbooks, operational playbooks, and admin training for local teams.

Deliverables

  • Firewall architecture and segmentation map.
  • Hardened device configurations and deployment templates.
  • Cleaned and optimized rulebase with risk-ranked inventory.
  • Monitoring dashboards, log forwarding configuration, and alerting rules.
  • Change control processes, runbooks, and audit evidence package.
  • Incident containment playbook and emergency contact procedures.

Engagement Models

  • Assessment & Optimization (2–6 weeks): rulebase audit, hit analysis, and remediation roadmap.
  • Managed Service: ongoing rule management, monitoring, tuning, and emergency change capability.
  • Project Deployments: new firewall deployments, cloud migration, or segmentation projects.
  • Hybrid: assessments plus managed handover or co‑managed operations.

Why choose us

  • Vendor‑agnostic expertise across major firewall platforms and cloud provider controls.
  • Operationally focused processes that reduce risk, lower alert noise, and maintain business continuity.
  • Measurable outcomes: reduced policy sprawl, faster emergency containment, and audit‑ready change records.
