Dedicated Network Engineering
We operate the network and security infrastructure for Sacramento, San Francisco, and Silicon Valley organizations where downtime isn't an option and auditors expect answers. A network-only managed service provider (MSP): firewalls, switching, wireless, VPN and monitoring, with no desktops and no help desk.
Monthly Managed network from $695/site/month; a single FortiGate from $199/month Fixed price Network Risk Assessment from $3,500 See pricing →
30 minutes with Jeff Johnson, founder, ex-Meta, senior network engineer (Cisco, Fortinet and CompTIA certified). Already have an IT provider? Keep them; we run the network layer alongside.
Start here
Design, fixes and day-to-day operations for your firewall, switching, Wi-Fi and WAN circuits (your internet connections and links between sites). Three ways to start.
Automated checks on every device in your plan, settings backed up so changes can be rolled back, and a monthly summary. Engineer response Mon–Fri, 8 AM–5 PM Pacific; the entry plan responds next business day and bills changes at $225/hr, 30-minute minimum.

One fixed price, set by how many sites, firewalls, switch groups, devices and access points you have. You get a report, a network diagram and a 30-60-90 day plan, ranked by risk. You keep all three. HIPAA, PCI DSS or SOC 2 mapping available.

FortiGate 60E end of support is December 29, 2026: after that date, Fortinet stops issuing security fixes for it. We pick the replacement, move your settings, and cut over on a schedule, with the old unit kept for rollback. Like-for-like swap labor $2,500 fixed; hardware quoted separately by part number. SSL-VPN conversion quoted after scoping.

Availability design target
99.99%
For fully redundant builds: HA firewalls, diverse ISPs and backed-up power.
Career totals, including prior-employer work. 99.99% (about 53 minutes a year) is a design target, not an SLA; service levels are set in each agreement.
Two firewall vendors, one flat VLAN, a single ISP, no failover, no logging. None of it was built for the reliability and compliance the business needed.
Case · regulated biotech · 3 sites · 2025
Illustrative schematic, phase 3 of 3, after the redesign: segmented VLANs, one firewall standard, ISP failover, redundant site-to-site VPN, full monitoring.
The redesign added VLAN segmentation across all sites, one firewall standard, ISP failover with automatic cutover, redundant site-to-site VPN and full monitoring; no site has had an unplanned outage since (as of October 2026).

Common signs
These rarely arrive as a ticket; they arrive as the outage nobody can explain, the audit that takes three weeks, or the change everyone postpones.
Select any that apply
Every change brings unplanned troubleshooting.
Nobody can say which firewall rules are still needed, or who added the last twenty.
There are two ISPs and two firewalls on paper, and the last time one actually failed, the site went down anyway.
Diagrams, configs and change records get pulled together the week the auditor asks, from memory and screenshots.
The same company runs five sites on five different standards.
The generalist MSP handles desktops, the ISP handles the circuit, and the firewall and switching in between are owned by no one.
Each one traces to a network managed without a design, a standard or an owner.
Who this fits: multi-site offices, healthcare, legal, financial services, SaaS offices and light industrial.
Why Ambio
One layer, run as a discipline: design standards, change control, monitoring and the audit evidence they produce.
No tiered queue. Business-hours calls and tickets go to the engineer who designed your network and holds its documentation.
Fortinet Engage partner and Fortinet reseller, with a published FortiGate model catalog. We also manage the Cisco, Aruba, Arista and other enterprise gear you already run.
Diagrams, as-builts, change records and configuration backups, yours to keep, whoever runs the network next.
Your Path
Managed plans and projects that change the design start with an assessment. Exceptions: single-FortiGate monitoring, like-for-like FortiGate swaps, prepaid hours, and management of a single firewall we installed or swapped. Full requirements →
We map what is actually installed: firewall rules, which devices can reach which, where settings have drifted from what was intended, and what would fail first.
A documented plan with clear standards, approved by you, before a single change is made. See a before-and-after design.
Rehearsed in our lab, scheduled with you, cut over with a rollback plan.
Devices and links on your plan checked every minute, every change recorded, a summary each month. See managed plans.
Monitoring and day-to-day operations, with you or for you.
Firewall migration from $6,500. A VPN-to-ZTNA move is quoted after scoping, because the work depends on your users, rules and applications.
Compliance work covers the network side of HIPAA, PCI DSS and SOC 2: segmentation, firewall change records and the evidence an auditor asks for.
Tekmirio design partners: by invitation.
On site in Sacramento, the San Francisco Bay Area and San Jose; remote across California and for multi-site organizations across the U.S. Local pages: Sacramento MSP, San Francisco MSP, San Jose MSP.
