Cybersecurity
Security treated as a property of the infrastructure: firewall policy, segmentation, and access control designed in from the start, not bolted on after.
Most security failures trace back to infrastructure decisions: flat networks, permissive firewall rules, exposed management interfaces. TCPGrid works at that layer, hardening the systems and network paths an attacker would actually use rather than selling a dashboard.
This is foundational security engineering: firewalls, VPNs, segmentation, and hardened configurations. It is the base layer that managed detection and response services build on top of.
What's included
Network security architecture
Designing perimeter and internal security controls aligned to how the network is actually segmented.
Firewall configuration & policy
Rule design, review, and lifecycle management focused on least-privilege access between segments.
VPN & secure remote access
Site-to-site and remote-access VPN architecture for distributed teams and multi-site businesses.
Network segmentation
Isolating critical systems from general user traffic to contain the impact of a compromised endpoint.
Security hardening
Reducing attack surface on network devices, servers, and management interfaces against known baselines.
Vulnerability assessment
Identifying exposed services, weak configurations, and outdated software before they're found by someone else.
How we approach it
Assess exposure
Review the current attack surface: firewall rules, exposed services, segmentation gaps.
Prioritize by risk
Rank findings by actual exploitability and impact, not by scanner severity scores alone.
Harden & remediate
Close the highest-risk gaps first, with changes staged to avoid breaking legitimate access.
Establish baselines
Document the hardened configuration as the standard for future changes and audits.
