Network Security for Toronto Businesses
Network security protects the infrastructure layer that all other business systems depend on. As GTA businesses move workloads to cloud platforms and support remote workers, the network security perimeter has evolved beyond physical firewalls to encompass cloud access, identity controls, and endpoint behaviour monitoring across distributed environments.
Network Security Services
- Next-generation firewall management: Configuration, rule management, and monitoring of NGFW platforms (Palo Alto, Fortinet, Cisco) with application-layer inspection and IPS capabilities.
- Network access control (NAC): Enforcing policies on which devices are permitted to connect to the corporate network and under what conditions.
- VPN and zero-trust access: Secure remote access for distributed workforces, replacing legacy VPN with zero-trust network access (ZTNA) where appropriate.
- DNS security: Blocking malicious domains at the DNS layer before connections are established - effective against phishing and malware C2 traffic.
- Network detection and response (NDR): Monitoring network traffic for anomalous patterns indicating lateral movement, data exfiltration, or active attack.
- DDoS protection: Upstream filtering and traffic scrubbing for organizations facing volumetric attack risk.
