Network & Security · Thunder Bay
Network security that's your first line of defence.
A properly designed network isn't just more reliable — it's your first line of defence against cyberattacks. We build, secure, and manage it for you.
Beyond the basic router.
Most small businesses run on whatever router the ISP installed — no VLANs, no proper firewall, guest WiFi mixing with employee devices. That's not a network, it's a liability.
DVG Systems designs networks that segment traffic, enforce access controls, and protect your data — without overcomplicating day-to-day operations. Pair this with our managed IT services for 24/7 monitoring and our backup and recovery solutions for defence in depth across network, endpoint and backup.
- Network design and architecture review
- Business-grade firewall installation and management
- VLAN segmentation (staff, guest, IoT, VoIP)
- VPN configuration for remote workers
- WiFi coverage design and access point deployment
- Ongoing security monitoring and threat alerts
Common problems we fix
- Slow or unreliable WiFi across the office
- Staff sharing network with public guest WiFi
- No visibility into what devices are on your network
- Remote workers connecting insecurely
- VoIP call quality problems caused by poor QoS
Security Services
Layered protection that covers the most common attack vectors for Northern Ontario businesses.
Firewall Management
Business-grade firewall configuration, rule management, and regular audits to close security gaps.
DNS Filtering
Block malicious websites and phishing domains before they reach your users — enforced at the network level.
Email Security
Anti-spam, anti-phishing, and external sender warnings — reduce one of the most common ransomware entry points.
Multi-Factor Authentication
MFA deployment across Microsoft 365, VPN, and remote access — dramatically reduces account compromise risk.

- Compliance guidance (PIPEDA, PHIPA, cyber insurance requirements)
- Quarterly security reviews and roadmap updates
- Vendor risk assessments
- Incident response planning and tabletop exercises
Real engagement
An account was taken while MFA was working
and was locked sixteen minutes after the attacker opened the mailbox — anonymised, with no invented figures.
