Firewall & Network Security Review
Most business firewalls ship with default rules that leave critical gaps, open ports, missing outbound controls, no logging. SNS audits your current firewall configuration, closes the gaps, and manages it ongoing so you never have to think about it again.
The Challenges Every HOA Faces
These aren't small inconveniences, they're operational drains that cost your association time, money, and resident trust every single day.
Open Ports You Don't Know About
Default firewall configs leave RDP (3389), SMB (445), and Telnet (23) exposed to the internet. These are the exact ports ransomware groups scan for first.
No Outbound Traffic Control
Most businesses only block inbound threats. Without outbound rules, malware already inside your network can freely call home, exfiltrate data, or download payloads.
Zero Firewall Logging
If your firewall isn't logging dropped packets and rule changes, you have no forensic trail. You won't know you were breached until it's too late, and neither will your cyber insurer.
Uncontrolled Application Access
Employees install apps that punch holes through your firewall. Without application-layer rules, any software can reach any destination, including attacker-controlled servers.
No Remote Management Policy
Remote work expanded your attack surface overnight. Without firewall rules scoped to specific IPs and VPN enforcement, every remote session is a potential entry point.
Compliance Gaps (HIPAA / PCI)
HIPAA and PCI-DSS both require documented firewall configurations, quarterly reviews, and network segmentation. Most SMBs fail these requirements without knowing it.
The average cost of a firewall misconfiguration breach for an SMB: $108,000
