Most breaches spread because the network was built flat and trusted by default - one foothold becomes full access. ALINEDS designs secure network architecture for government and regulated organizations: zero-trust segmentation, least-privilege access boundaries, and system hardening engineered in from the start rather than bolted on after an audit finding. We align designs to NIST SP 800-207 zero-trust principles and NIST 800-53 control families, so your security posture is structural - the network itself limits how far any attacker can move.
Why it matters
For public-sector and regulated organizations, a flat, over-trusted network is the difference between an incident contained to one system and one that reaches everything. Federal direction (NIST 800-207, CISA's Zero Trust Maturity Model) is pushing agencies toward zero trust for exactly this reason. Getting the architecture right upfront is far cheaper than remediating breaches or failed audits later.
What you get
Zero-trust network design
We design around verify-explicitly, least-privilege, and assume-breach so trust is never granted by default.
Segmentation & micro-segmentation
We divide the network so a compromise in one zone can't move laterally into others.
System & device hardening
We harden servers, endpoints, and devices to recognized baselines to shrink the attack surface.
Secure-by-design reference architectures
We document target-state designs your team can operate and extend.
Identity & access boundaries
We define least-privilege boundaries so users and services reach only what they need.
Alignment to federal zero-trust guidance
We map the design to NIST 800-207 and the CISA maturity model to support your compliance path.
How it works
Assess
Map your current network, trust relationships, and exposure.
Design
Produce the target zero-trust architecture and segmentation plan.
Segment & harden
Implement segmentation and hardening against recognized baselines.
Document & hand off
Deliver reference architecture and guidance your team can run.
Where it fits
Zero-trust roadmap for an agency
Assess maturity against the CISA model and lay out a phased path to zero trust.
Segmenting a flat legacy network
Introduce segmentation so a single compromise can't reach critical systems.
Securing OT / critical systems
Isolate and harden sensitive operational systems from general IT.
Post-audit remediation by design
Turn audit findings into a hardened architecture rather than point fixes.
Key distinctions
Zero trust vs. perimeter (castle-and-moat)
| Aspect | Zero trust | Perimeter model |
|---|---|---|
| Default trust | Never - verify every request | Trusted once inside |
| Lateral movement | Contained by segmentation | Free once perimeter is breached |
| Access | Least-privilege, per resource | Broad network access |
| Identity | Central to every decision | Perimeter-centric |
| Federal direction | NIST 800-207 / CISA aligned | Legacy approach |
Compliance & security
Structural security, mapped to federal standards
Designs map to NIST SP 800-207 (zero trust) and NIST 800-53 boundary-protection (SC-7) and access-control families, and support CJIS network requirements for justice agencies. Security is built into the architecture, so your controls and your audit evidence come from the same design.

Key terms
- Zero trust
- A security model that trusts no user, device, or connection by default and verifies every access request explicitly.
- Micro-segmentation
- Dividing a network into small, isolated zones so an attacker can't move freely between systems.
- Attack surface
- The sum of all points where an attacker could try to enter or extract data; hardening reduces it.
Frequently asked
What is zero trust and does my agency need it?
Zero trust assumes no user, device, or connection is trusted by default - everything is verified and granted least-privilege access. For government it's the current federal direction (NIST 800-207) and the most effective way to limit how far an attacker can move.
How is this different from just buying firewalls?
Firewalls are one control; architecture is the blueprint that decides where they go and what they protect. We design how the whole network is segmented, trusted, and hardened so tools work together instead of leaving gaps.
Can you work with our existing network and vendors?
Yes. We design around what you already own and standardize on your platforms, improving segmentation and hardening without a rip-and-replace.
Do you align to NIST 800-207 and the CISA maturity model?
Yes. Our zero-trust designs follow NIST 800-207 and map to the CISA Zero Trust Maturity Model and NIST 800-53 controls.
What is micro-segmentation and why does it matter?
It divides your network into isolated zones so a compromise in one can't spread to others - containing attacks and satisfying boundary-protection requirements.
Where do we start if our network is flat?
Usually with an assessment and a phased segmentation plan that isolates your most critical systems first, then expands.
