A firewall is only as strong as how it's configured and maintained - and misconfiguration, not the product, is where most network exposure comes from. ALINEDS deploys, configures, and manages enterprise firewalls and network security, with hands-on depth in Fortinet FortiGate, Cisco ASA, Palo Alto Networks, and SonicWall. We turn next-generation firewalls into enforced policy: segmented networks, controlled traffic, and boundaries that hold up to both attackers and auditors - and we keep them that way as rules and threats change.
Why it matters
Firewalls quietly drift toward risk: rules pile up, exceptions become permanent, and no one owns the cleanup. For government and regulated networks, that drift is both a breach risk and an audit finding waiting to happen. Disciplined deployment, segmentation, and ongoing management are what keep the firewall an actual control instead of a false sense of security.
What you get
Firewall deployment & configuration
We deploy and configure Fortinet, Cisco, Palo Alto, and SonicWall to a secure baseline.
Next-generation firewall policy
We build application-aware policy with intrusion prevention where needed.
Segmentation enforcement
We enforce network boundaries and segmentation at the firewall.
Rule management & change control
We manage rules and changes to prevent sprawl and drift.
Vendor depth across platforms
We work across the major firewall platforms - Fortinet FortiGate, Cisco ASA, Palo Alto Networks, and SonicWall - so recommendations fit your environment instead of a single vendor's catalog.
Ongoing tuning
We keep policy tight and current as your environment changes.
How it works
Design policy
Define the firewall and segmentation policy for your environment.
Deploy & configure
Stand up or reconfigure firewalls to a secure baseline.
Enforce segmentation
Implement the boundaries that contain threats.
Manage & tune
Maintain rules and change control over time.
Where it fits
Firewall refresh or migration
Deploy or migrate to a next-generation platform cleanly.
Taking over managed firewalls
Assume configuration and rule management of existing firewalls.
PCI / CJIS segmentation
Implement the network segmentation those mandates require.
Rule-base remediation
Audit an over-permissive, sprawling rule base, remove stale and shadowed rules, and tighten access to what's actually needed - then keep it clean with change control.
High-availability firewall design
Deploy redundant, failover-ready firewalls so a hardware or link failure doesn't take your network - or its protection - offline.
Key distinctions
Next-generation firewall vs. traditional firewall
| Aspect | Next-generation firewall | Traditional firewall |
|---|---|---|
| Awareness | Application- and user-aware | Port/protocol only |
| Threat prevention | Built-in IPS & inspection | Basic filtering |
| Segmentation | Fine-grained | Coarse |
| Visibility | Deep traffic insight | Limited |
| Fit for gov/regulated | Yes | Often insufficient |
Compliance & security
Boundaries that satisfy the mandates
Firewall and segmentation controls support NIST 800-53 SC-7 boundary protection, PCI-DSS network segmentation, and CJIS network security requirements. Disciplined configuration and change control keep those controls effective - and auditable - over time.

Key terms
- Next-generation firewall (NGFW)
- A firewall that adds application awareness, user identity, and intrusion prevention beyond basic port/protocol filtering.
- Network segmentation
- Dividing a network into zones with controlled traffic between them to contain threats.
- Rule sprawl
- The accumulation of stale, redundant, or over-permissive firewall rules that widen risk over time.
Frequently asked
Which firewall platforms do you support?
Hands-on depth in Fortinet FortiGate, Cisco ASA, Palo Alto Networks, and SonicWall - design, deploy, and manage across them.
Do I need a next-generation firewall?
If you need application-aware control, intrusion prevention, and segmentation - most government and regulated environments do - then yes. We right-size the platform rather than over-buy.
Can you manage the firewalls we already own?
Yes. We can take over configuration, rule management, and tuning, or deploy new ones where needed.
How does firewall segmentation reduce our risk?
It divides the network so a compromise in one zone can't spread freely, containing attacks and satisfying PCI-DSS and CJIS boundary requirements.
What is "rule sprawl" and why is it a problem?
It's the buildup of stale, redundant, or over-permissive rules over time - each a quiet widening of your attack surface. We audit and tighten it.
How is this different from your Security Architecture service?
Architecture designs the overall secure network; this service deploys and manages the firewalls that enforce it. They work together.
How often should firewall rules be reviewed?
At least annually and after any major change - but the bigger win is ongoing change control so rules never drift far in the first place. We can review periodically or manage it continuously.
