Network, security & managed IT services: Every layer of your network, engineered by one team.
Arpgate designs, builds, secures and operates enterprise networks, from the patch panel to zero trust access. One accountable team, on-site and remote, for government agencies, regulated enterprises and companies.
- Engineering experience since 2009
- On-site and remote
- USA and international
Capabilities
Four practices. One accountable engineering team.
Network problems rarely stay in one lane. A wireless complaint turns out to be a NAC policy. A slow application turns out to be a routing decision. Our practices work as one team, so the answer does not stop at a vendor boundary.
01
Network Engineering
Architecture and hands-on engineering for campus, WAN and data center networks, and the administration that keeps them sound.
-
Network Design & Engineering
Architecture built around how your organization works: requirements, high- and low-level designs, IP and VLAN plans, segmentation and migration strategy, followed by the engineering and administration to keep it sound.
HLD & LLD · IP addressing · Segmentation · Migration planning
-
Routing & Switching
Installation, configuration and troubleshooting of enterprise routers and switches across campus access, distribution and core, the WAN edge and the data center.
OSPF & BGP · VLANs & STP · VRRP · EVPN-VXLAN
02
Security & Access
Control who and what connects, inspect what moves across the network and give users secure access to applications wherever they work.
-
Next-Generation Firewalls
Next-generation firewall deployment, configuration and policy management, from new installations and migrations to rule base cleanup and application-aware policy.
Application-aware policy · Remote access VPN · Central management · Rule base reviews
-
Network Access Control
Identity-based access control across wired, wireless and VPN connections: 802.1X, MAB, device profiling, posture and guest onboarding, rolled out in phases from monitor mode to enforcement.
802.1X · RADIUS · Profiling · TACACS+
-
Zero Trust Access
Security service edge (SSE) configured and supported end to end: zero trust access to private applications, a cloud-delivered secure web gateway and digital experience monitoring.
ZTNA · Secure web gateway · TLS decryption · Experience monitoring
03
Wireless & Infrastructure
The foundation everything else depends on: wireless that covers and roams, and physical plant that is built to standard, labeled and tested.
-
Enterprise Wireless
Wireless designed for coverage, capacity and roaming: predictive and on-site surveys, RF design, controller and access point configuration, and ongoing support.
Site surveys · RF design · WPA3 · Roaming
-
Structured Cabling & Infrastructure
Physical installation done to standard: racking, wall jacks, patch panels, AP mounting, fiber, cable management, power, labeling and testing.
Racking · Fiber · Labeling · Testing
04
Managed Network Services
Ongoing operation by engineers who understand your network, fully managed or co-managed with your own team.
Managed Network Services
Proactive monitoring, maintenance and expert support for your network. Choose fully managed operations, or a co-managed model that works alongside your IT team with clear lines of responsibility.
- Proactive monitoring and alert triage
- Firmware, patching and lifecycle planning
- Configuration backups and change control
- Troubleshooting and incident support
- Regular health reviews and recommendations
Platform experience: Cisco · Palo Alto Networks · Aruba · Zscaler
Engagement models
Work with us the way your program runs.
Some programs need a defined project. Others need an engineer on site next week, or a partner to run the network day to day. Choose the model that fits, and change it as your needs change.
-
Defined scope
Project delivery
A defined scope, a design you approve and a delivery plan with milestones. Arpgate owns the outcome from kickoff to as-built documentation.
- Best for
- Refreshes, migrations, new sites and security rollouts.
- You receive
- A statement of work, design documents, implementation and a documented handover.
-
Clear picture
Assessments
An independent review of your network, security controls or readiness for a major change. Findings are ranked by risk and effort, with no product pitch attached.
- Best for
- Pre-migration planning, audit preparation, inherited networks and persistent performance problems.
- You receive
- Current-state documentation, prioritized findings and a practical roadmap.
-
Extra hands
Staff augmentation and on-site engineering
Experienced network engineers who join your team on site or remotely, working inside your processes, tools and change control.
- Best for
- Backlogs, cutover weekends, rollouts across many sites and gaps between hires.
- You receive
- Engineers matched to your technology and environment, directed by your team.
-
Ongoing care
Managed and co-managed operations
Arpgate monitors, maintains and supports your network, either fully or alongside your internal team with an agreed split of responsibilities.
- Best for
- Lean IT teams, multi-site organizations and networks that need consistent care.
- You receive
- Proactive monitoring, maintenance, change management and regular reviews.
How we work
A disciplined path from first call to handover.
Every engagement follows the same four phases. The depth scales with the scope. The discipline does not.
-
01
Discover
We learn the environment before we change it: goals, constraints, topology, configurations, pain points and compliance requirements.
- Current-state review
- Requirements and constraints
- Risks ranked by priority
-
02
Design
Requirements become an architecture you can approve, with a bill of materials, a test plan and a migration strategy that includes rollback.
- High- and low-level designs
- Bill of materials
- Migration and rollback plan
-
03
Deliver
We build and cut over in controlled stages, inside your change windows, and validate each step against the test plan before moving on.
- Staged implementation
- Method of procedure per change
- Validation results
-
04
Hand over and support
We document what we built and transfer the knowledge. Then your team runs it, or we run it with you.
- As-built documentation
- Runbooks and walkthroughs
- Managed or co-managed support
What you can expect
Standards we hold on every engagement.
Technology changes. The way we work does not. These practices apply whether the job is one wiring closet or a multi-site program.
About Arpgate-
Documentation you own
As-built diagrams, configurations, IP plans and runbooks, delivered in formats your team can maintain.
-
Controlled change
Every change has a method of procedure, an approved maintenance window, a validation step and a rollback plan.
-
Security by default
Hardened baselines, least-privilege access and centralized logging, designed with frameworks like NIST SP 800-53 and NIST CSF in mind.
-
Knowledge transfer
Walkthroughs and handover sessions, so your team understands what was built and why each decision was made.
-
On-site and remote
Engineers on site when the work needs hands, and remote when it does not, in line with US regulations.
-
Plain-language reporting
Clear status, risks and decisions for program managers and executives, alongside the technical detail engineers need.
Questions to ask before you engage us.
Have a question that is not answered here? Talk to an engineer.
Yes. We start from the network you have: we assess it, keep what is sound and recommend replacements only where lifecycle, security or capacity requires it.
Both. Our team works on-site and remote, in line with US regulations, for organizations in the USA and internationally. Physical installation and cutovers usually happen on site; design, configuration and support are often remote.
No. Our services are defined by technology: routing and switching, firewalls, access control, zero trust access and wireless. Our engineers have hands-on experience with the major enterprise platforms, and real networks are multi-vendor, so we engineer across the whole path between your users and their applications.
Yes. An assessment or a single-site project is a good starting point. It gives both teams a clear picture of the environment before any larger commitment.
Managed means Arpgate runs day-to-day network operations for you. Co-managed means we share the work with your IT team under an agreed split of responsibilities, tools and escalation paths. Learn more about managed services.
