Network & Infrastructure Security
Protecting your network infrastructure, from the firewall edge to individual devices, from unauthorized access and lateral spread.
Who this is for: Businesses whose network has grown organically for years without anyone reviewing the whole picture at once.
The Problem
One infected laptop can become a company-wide incident when the network itself doesn’t stop it from spreading.
Our Solution
We review, segment, and harden the network itself, firewall policy, segmentation, wireless, and remote access, so a single compromised device stays contained.
What's included
- Firewall rule review and cleanup
- Network segmentation so a compromised device is contained
- Wireless network security audits
- VPN and remote-access hardening
- Intrusion detection/prevention (IDS/IPS) review
- Router and switch hardening
- Zero Trust readiness assessment
- Ongoing configuration drift monitoring
Flat networks are the reason a single infected laptop turns into a company-wide incident. Segmentation, tight firewall policy, and hardened remote access are unglamorous work, but they’re what actually contains a breach before it spreads.
If remote access to a specific machine or server is the concern, not the broader network, see our dedicated Remote Access Security service, which covers replacing exposed RDP and similar direct-access setups with something safe.
Benefits
- A compromised device stays contained instead of spreading company-wide
- A documented, auditable network baseline instead of years of accumulated shortcuts
- Fewer stale or overly-permissive firewall rules nobody can explain
Our Process
Firewall Review
Clean up overly permissive or stale rules.
Segmentation Review
Separate guest, IoT, and critical systems onto distinct zones.
Remote Access Review
Check VPN configuration, split-tunneling, and MFA enforcement.
Wireless Review
Verify guest isolation, encryption, and password rotation.

Frequently asked questions
How is this different from Remote Access Security?
Remote Access Security focuses specifically on how you reach a machine remotely (VPN, RDP, ZTNA). Network Security covers the broader picture, firewall policy, segmentation, and wireless, that determines what happens once someone (or something) is already on the network.
Do you help with Zero Trust?
Yes, as part of a network assessment we can evaluate readiness for a Zero Trust model and implement identity-based access controls where it makes sense for your environment, without requiring a full rip-and-replace.
