OSHEAN Managed Firewall Services

OSHEAN Managed Firewall Services

OSHEAN Managed Firewall Services deliver enterprise-grade perimeter security through a dedicated Fortinet Virtual Domain (VDOM), fully operated and monitored by OSHEAN’s Network Operations Center (NOC).

Each member receives a logically isolated firewall environment with professional security management, built-in high availability, and clearly defined service commitments. Members define the policies and rules required to secure their networks, while OSHEAN provides the platform, operations, and expert support necessary to ensure effective implementation.

By managing the infrastructure, availability, and day-to-day operations of the platform, OSHEAN enables organizations to benefit from advanced firewall protection without the burden of purchasing, maintaining, or staffing complex security appliances. This service is particularly valuable for organizations seeking strong, reliable security controls without dedicated firewall administration resources.

Dedicated & Isolated Firewall Environment

Each organization operates within its own secure and independent Fortinet Virtual Domain (VDOM), providing enterprise-grade firewall capabilities without sharing policies, configurations, or risk with other tenants.

• Dedicated Fortinet VDOM assigned to your organization
• Complete logical separation from other OSHEAN members
• Independent policies, routing, and VPN configurations
• Administrative access to review and manage configurations

This architecture provides members with complete control over their security policies and network configurations while eliminating the costs and operational overhead associated with owning and maintaining physical firewall hardware.

Enterprise-Grade Security Controls

OSHEAN delivers multiple layers of security protection designed to help defend networks against modern cyber threats while simplifying day-to-day security operations.

• Firewall rule implementation and ongoing management
• Intrusion Prevention System (IPS)
• Unified threat protection with continuously updated threat intelligence
• Web and application filtering capabilities
• Secure VPN connectivity with Multi-Factor Authentication (MFA) support

These controls help reduce exposure to malware, ransomware, unauthorized access attempts, and other emerging threats while supporting secure access for staff, partners, and remote users.

High Availability Architecture

The firewall platform is designed to maintain service continuity during maintenance activities, hardware failures, and localized outages through a resilient, highly available architecture.

• Redundant firewall infrastructure
• Deployment across geographically distributed OSHEAN data centers
• Built to minimize service interruptions during maintenance or failure events

Members benefit from consistent firewall availability, reduced downtime risk, and confidence that critical security protections remain in place when needed most.

24×7 Monitoring & Operations

OSHEAN’s Network Operations Center continuously monitors firewall health, performance, and security activity, ensuring members are never solely responsible for detecting or responding to potential incidents.

• Continuous monitoring and alerting
• Proactive response to security events
• Real-time coordination during incidents and maintenance activities
• Flexible support for member-requested firewall changes

Members may manage updates independently or collaborate with the OSHEAN NOC to implement firewall policy and rule changes securely.

Lifecycle & Patch Management

OSHEAN manages the ongoing maintenance required to keep firewall infrastructure secure, stable, and aligned with vendor best practices.

• Regular firmware upgrades and security patching
• Rapid response to critical Fortinet vulnerabilities
• Configuration backup and recovery support
• Emergency security fixes when required

This proactive approach helps reduce exposure to known vulnerabilities while maintaining platform stability through tested, vendor-recommended software releases.

Visibility & Control

Members maintain transparency into firewall operations while benefiting from collaborative support and centralized platform management.

• Logging and reporting for troubleshooting and security reviews
• Auditable change tracking and documentation
• Administrative access to your assigned VDOM
• Collaborative policy management with OSHEAN engineers

These capabilities support compliance initiatives, security audits, operational troubleshooting, and ongoing policy refinement.

OSHEAN Security Ecosystem Integration

OSHEAN Managed Firewall Services integrate with additional security offerings to provide layered defense and comprehensive protection across the member environment.

• Cisco Umbrella DNS Protection
• OSHEAN DDoS Detection and Mitigation Services
• Fortinet SD-WAN Services
• Cisco Duo and identity-based access controls
• Secureworks VDR, Armis, and Apptega integrations
