How We Protect Your Network Data Infrastructure

We provide comprehensive network data security services that address your network architecture, access controls, traffic segmentation, and connectivity — building a layered defense that protects data at every point in its journey across your organization.
Network Assessment

Network Assessment

Identify gaps before they become network incidents.

We evaluate your current network infrastructure against security best practices to identify gaps, misconfigurations, and performance constraints — before they become incidents:

  • Network topology discovery and documentation
  • Traffic flow analysis and bandwidth capacity review
  • Security configuration review across all network devices
  • Vulnerability and risk identification
  • Prioritized remediation roadmap with clear timelines
Network Assessment = Informed Architecture Decisions
Network Segmentation

Network Segmentation

Isolate critical systems and contain risk.

We design and implement network segmentation strategies that isolate critical systems and limit the blast radius of any security incident:

  • VLAN design and implementation
  • Micro-segmentation for sensitive and regulated workloads
  • Access control list configuration and validation
  • Zero trust network architecture planning
  • Segmentation validation and penetration testing
Network Segmentation = Contained Risk
Firewall Security and Policy Management

Firewall Security & Policy Management

Enforce access control across your network perimeter.

We configure and manage your firewall infrastructure to enforce access controls and protect your network perimeter from unauthorized traffic:

  • Firewall rule review, cleanup, and optimization
  • Security policy design and implementation
  • Next-generation firewall deployment and configuration
  • Firewall change management process and documentation
  • Ongoing policy review, maintenance, and audit support
Firewall Security = Enforced Access Control
SD-WAN Design and Implementation

SD-WAN Design & Implementation

Secure, high-performance connectivity across locations.

We design SD-WAN solutions that deliver secure, high-performance connectivity across all your locations — replacing unreliable or expensive legacy WAN infrastructure:

  • SD-WAN architecture design and vendor selection
  • Support for Fortinet, Cisco, and Meraki SD-WAN platforms
  • WAN optimization and traffic prioritization configuration
  • Application-aware routing policy design
  • Failover, redundancy, and high-availability design
SD-WAN = Reliable, Secure Connectivity
Network Incident Remediation

Network Incident Remediation

Fast containment and recovery when incidents happen.

When network incidents occur, we respond quickly to contain and resolve them with minimal disruption to your business operations:

  • Rapid triage and network isolation
  • Root cause analysis and forensic investigation
  • Configuration rollback and recovery
  • Post-incident hardening and gap closure
  • Full documentation and lessons-learned review
Fast Remediation = Minimal Business Disruption

    FAQs

    Network data security refers to the set of controls, policies, and technologies used to protect data as it flows across your network infrastructure. It encompasses firewall security, access controls, network segmentation, encryption in transit, and continuous monitoring — all designed to ensure your data can only be accessed by authorized users and systems. OnionGrid delivers network data security services for businesses across Canada.
    A network assessment is a comprehensive evaluation of your existing network infrastructure, including topology, performance, security configurations, and vulnerability exposure. It identifies risks, gaps, and opportunities for improvement — and results in a prioritized roadmap for remediation and optimization. OnionGrid’s network assessments cover both security posture and operational performance, giving you a complete picture of your network environment.
    Network segmentation divides your network into isolated zones, ensuring that a compromise in one area cannot easily spread to the rest of your environment. It limits the blast radius of cyberattacks such as ransomware, restricts lateral movement by attackers who gain initial access, and helps enforce least-privilege access principles. OnionGrid designs and implements network segmentation strategies tailored to your business and compliance requirements.
    Firewall security involves using hardware or software-based firewalls to control the flow of traffic in and out of your network based on defined security policies. Modern next-generation firewalls (NGFW) also perform deep packet inspection, application-layer filtering, intrusion prevention, and integrated threat intelligence. OnionGrid configures, manages, and optimizes firewall security across Cisco, Palo Alto, and Fortinet platforms.
    SD-WAN (Software-Defined Wide Area Network) is a technology that decouples network management from the underlying hardware, enabling intelligent, policy-driven routing of traffic across multiple WAN links. It improves performance, resilience, and security for businesses with multiple locations or cloud-heavy workloads — while reducing reliance on expensive MPLS circuits. OnionGrid designs and implements SD-WAN solutions across Fortinet, Cisco, and Meraki platforms.
    A network assessment should be conducted at minimum once per year, and more frequently following significant changes to your infrastructure, after a security incident, or when adding new locations, users, or cloud services. Regular assessments ensure your network security posture keeps pace with your evolving business environment and the current threat landscape.
    Yes. OnionGrid works with multi-vendor environments across Cisco, Palo Alto, Fortinet, Meraki, Juniper, and other major platforms. We assess your existing infrastructure first, then design solutions that integrate with what you have — or recommend targeted upgrades where security and performance requirements justify them.
    Network support encompasses the day-to-day monitoring, maintenance, troubleshooting, and optimization of your network infrastructure. This includes managing network devices, responding to outages, implementing changes with proper change control, and ensuring the network performs reliably to meet your business needs. OnionGrid provides ongoing network support as part of both managed IT and dedicated network data security engagements.
    Most Canadian privacy and security regulations — including PIPEDA — require organizations to implement appropriate safeguards to protect the personal and sensitive data they handle. Network data security controls such as access management, encryption, segmentation, and monitoring are foundational to demonstrating compliance. OnionGrid designs network data security solutions with Canadian regulatory requirements built directly into the architecture.
    Network security focuses on protecting the network infrastructure itself — firewalls, switches, routers, and the controls that govern access and traffic flow. Network data security has a broader scope, encompassing the protection of data as it moves across the network, including encryption, data loss prevention, and access control to sensitive data repositories. Both disciplines work together as part of a comprehensive security posture.
