A flat network means one compromised laptop can reach everything. Segmentation is what turns a bad day into a contained one.
Recommended ModuleCarriers ask about network segmentation and remote access because they’re the difference between an incident and a catastrophe. On a flat network, ransomware that lands on one machine spreads to your servers and backups in minutes. And exposed remote access — an open RDP port, a VPN without MFA — is one of the most common ways attackers get in at all.
The three things they’re really asking: Is your network segmented so sensitive systems are isolated? Is remote access locked behind a VPN and MFA? And are your firewall and network devices actually hardened, not running on defaults? If your network is "one big flat thing," this kit shows you how to change that.
Put guests on their own Wi-Fi.
If visitors and staff share one Wi-Fi network, split them today. Most business routers can broadcast a separate guest network in a few clicks. It’s the simplest segmentation there is and it keeps untrusted devices off your internal systems.
Turn off internet-exposed remote access.
Check whether RDP (port 3389) or SSH is reachable from the internet on any system. If it is, close it and put remote access behind a VPN with MFA. Exposed RDP is one of the single most exploited entry points.
Change one default password.
Log into your main firewall or router and confirm the admin password isn’t still the default. Change it, and enable automatic firmware updates while you’re there. Default credentials on network gear are trivial for attackers to find.
If the quick wins showed you the gap but not the path, the kit gives you a complete network-security program — a segmentation plan, a remote-access standard, and hardening checklists — without a network consultant.
Network Security Policy
The policy behind your network controls. Pre-structured; adapt and adopt.
Network Segmentation Plan
Define your zones and the rules between them so a compromise can’t reach everything.
Remote Access Standard
VPN, MFA, no exposed RDP, and time-limited vendor access — the controls that close the most common entry point.
Wireless Security Checklist
Separate guest Wi-Fi, strong encryption, changed defaults — lock down the doorway.
Network Device Hardening Checklist
Harden every router, switch, and firewall instead of running them on defaults.
Firewall Rule Review Log
Review and clean up firewall rules on a cadence so stale holes don’t accumulate.
Some networks need to be re-architected, not just documented.
If your Whitestance score flagged Network Security as a critical gap — or if you have multiple sites, legacy gear, or sensitive systems on a flat network — a kit gets you the plan but a full engagement gets it implemented. Whitestance’s fractional CISO engagements design and help implement segmentation and secure access across your environment, with documented evidence your board, auditors, and carriers can see. Engagements start at $40,000 for smaller organizations and scale from there.
