Network
Hardening
Less attack surface. More sleep. We segment what matters, kill the legacy pathways, and continuously validate that what you locked down stays locked down.
Plain English
What is
Network Hardening?
Network hardening is the disciplined process of reducing your network's attack surface, segmenting traffic by trust boundary, tightening every configuration, removing unnecessary services, and continuously validating that the controls are actually working. Done right, it transforms an environment where an attacker can move freely into one where they trip a wire on the first wrong step.
What's Included
What's
In Scope
Discovery & Asset Mapping
Map every device, every flow, every trust boundary. You can't harden what you don't know exists.
Gap Assessment
Compare your current state against NIST, CIS, and the threat model that fits your industry. Score the gaps. Prioritize by exploitability and blast radius.
Segmentation Design
Zero-trust micro-segmentation or pragmatic VLAN-and-ACL, whatever fits your stack and budget. We don't sell ideology.
Firewall & Switch Hardening
Rule cleanup, configuration baselines, IPS tuning, and deny-by-default postures. Documented, version-controlled, and reviewed.
IAM & Access Review
Privileged access pathways, lateral movement opportunities, service accounts. We trace what an attacker would actually try.
Continuous Validation
Periodic re-scanning, drift detection, and tabletop exercises so hardening doesn't quietly erode after handoff.
How We Engage
Our
Approach
-
Assess
Discover, map, and rank. Two-week sprint that ends with a heat-map of your current exposure and a prioritized fix list.
-
Architect
Design the target state, segmentation, identity boundaries, monitoring. Reviewed with your team before a single change is made.
-
Implement
Phased rollout with rollback plans. Off-hours change windows for risky moves. Constant monitoring during cutover.
-
Validate
Internal pen test or purple team exercise to prove the new posture works. Documentation, training, and a 90-day tune-up.

Vendors We're Deep On
Who This Is For
You'll Recognize
Yourself Here
Post-pentest cleanup
Your latest pentest read like a horror novel. We turn the report into a prioritized, costed remediation.
M&A integration
You just acquired a company. You inherited their networks, and their gaps. We segment cleanly before threats cross.
Regulated industries
HIPAA, PCI, SOX, FedRAMP. You need network controls that withstand auditor scrutiny.
After a near-miss
Threat actor was in the door but didn't make it deep. You want to make sure the next one doesn't either.
Pre-IPO posture
You're hardening for due diligence. We baseline the network against frameworks your acquirer will audit against.
Multi-site retail / healthcare
Hundreds of locations, one playbook. We design segmentation that scales.
Partner of Choice
Why Tech Critic
Real architects on day one
Senior infrastructure architects, not pre-sales people in disguise. We bring scars, not slides.
Fixed-scope, milestone-based
You'll get a written estimate before any work begins. Most engagements are priced by deliverable, not by the hour.
We own the outcome end to end
From design through cutover through 90-day post-launch tune-up. We don't disappear after kickoff.
Five offices, one standard
Dallas (HQ), Bogotá and Medellín (LATAM), Pakistan and Dubai. Every office is ours. We don't outsource.
You've Got Q's
We've Got A's
Don't see your question? Just ask.
Do you actually do zero-trust, or just talk about it?
We do it where it pays off and skip it where it doesn't. Most clients land on a pragmatic hybrid: zero-trust for identity and critical-asset access, traditional segmentation for the rest. We don't sell ideology. We sell working networks.
How long does a hardening engagement take?
Assessment phase is typically 2 to 4 weeks. Implementation runs 8 to 16 weeks for a mid-sized environment, broken into phases so you can pause or pivot. Multi-site and global rollouts run 6 to 9 months.
Will this break anything?
We design every change with a rollback plan and a change-window. Most hardening can happen during business hours with zero impact; the risky bits get scheduled and communicated. We don't break things that aren't already broken.
Can you work with our existing vendors?
Yes. We're vendor-neutral across Palo Alto, Cisco, Fortinet, Juniper, and the cloud-native NSGs. We extend what works and replace only what we have to.
