Firewall & Network Security Services
We supply, install and manage firewalls, VPNs and endpoint protection so your office network stays fast, filtered and closed to attackers. Exelon Circuits sets up network security for modern workplaces, healthcare facilities, campuses and industrial plants, and keeps it updated with ongoing monitoring.
What we set up and manage
Comprehensive technical solutions engineered for security, reliability and measurable business outcomes.
Next-generation firewall (UTM/NGFW)
Supply, rack, configure and license firewalls sized to your users and internet speed.
Web & content filtering
Block malicious and unwanted sites by user group, as required in schools and many offices.
Secure remote access (VPN)
Staff and branches connect safely from home or other cities using SSL or IPsec VPN.
Multi-ISP failover & load balancing
Two internet lines, automatic switchover, so a single ISP outage doesn't stop work.
Network segmentation (VLANs)
Separate guest Wi-Fi, CCTV, billing and office networks so one breach can't spread.
Endpoint protection / EDR
Managed antivirus and endpoint detection on laptops and servers.
Email security
Spam, phishing and spoofing protection for Microsoft 365 and Google Workspace, with SPF, DKIM and DMARC set up correctly.
Managed firewall service
Firmware updates, rule reviews, log monitoring and monthly reports.
