NetSys vs. ExterNetworks
ExterNetworks is not the same species of company as most firms on this list. They sell network operations, field dispatch and outsourced service desks at national scale, out of Piscataway. This page reads their published positions against ours, so you can work out which shape of provider your problem calls for.
The short answer
They are not competing for quite the same job. ExterNetworks publishes an ITIL-certified operations team, a large field technician bench and service levels shaped per client, which suits a company needing hands in many states or a network operations center behind its own IT staff. NetSys is a single engineering practice in Brooklyn that takes the whole environment on one agreement, month to month, security and AI included. Choose by shape, not by feature list.
What ExterNetworks is
ExterNetworks operates from Piscataway, New Jersey, and lists six more offices across the United States and Canada, including Long Island City. Their about page says the company has run since 2001 and publishes a headcount of more than 500 full-time employees plus over 1,000 field technicians. They also name two certifications the company itself holds, ISO 27001:2022 and SOC 2, which is a stronger form of evidence than naming frameworks you help clients meet. The service menu is organized around managed communication, data analytics, networking and infrastructure, security as a service, and build as a service.

Recovery testing published as part of service
Testing is where most recovery plans quietly fail, so it counts that their managed disaster recovery page puts testing inside the service: solution auditing, failover testing and regular testing of the deployment, with automated runbooks and round the clock monitoring of the recovery environment behind it. That is one of the better recovery pages in this batch and it deserves the credit. Our version of the same commitment is a written plan plus restores we perform and time, backed by more than 30 ransomware incidents handled in three years, every one fully recovered.
Capacity you rent against a practice you hire
A bench of field technicians and an ITIL-certified operations center is capacity. You buy it by the ticket, the site or the service level, and it scales across states without anyone needing to know your business in detail. That model earns its keep when you have forty branches and a rollout. NetSys is the other trade: one team, one office in Brooklyn, and engineers who carry your environment in their heads because they built most of it. Neither model is better in the abstract; they answer different questions.
Two ways to write a service level
Service levels get written two ways. Theirs can be shaped to the client's requirements, with the available metric types listed on the page, which is how enterprise contracts normally get built and it gives a procurement team something to negotiate against. We take the same problem somewhere else: response commitments go into the agreement, and the agreement itself runs month to month, so the number and the exit sit in one document. What a term looks like on their side we could not determine from the site, so that conversation comes before the service level one.
What each of us publishes
Their column is quoted from pages on extnoc.com and links to each one. Ours states what we commit to elsewhere on this site. Nothing below is our opinion of their work.
| The NetSys Group | ExterNetworks | |
|---|---|---|
| Agreement | Month to month. Leave any time, no early-exit penalty. | The Terms & Conditions page linked from their site footer is a website terms-of-use document governing use of the website. (extnoc.com) |
| What the monthly fee covers | One agreement: AI services, cybersecurity, managed IT with help desk, PAM, PIM and disaster recovery planning. | Their corporate site's managed services page lists five service categories: Managed Communication, Data Analytics, Networking and Infrastructure, Security as a Service, and Build as a Service. (externetworks.com) |
| Privileged access and credentials | PAM and PIM in the base agreement, each with a published service page describing the work. | We could not find privileged access, privileged identity management or managed credentials named on their site. |
| AI and automation | In-house practice led by Jamie Baum: readiness assessments, Copilot rollouts, custom agents and workflow automation. | Their corporate site publishes an artificial intelligence page listing four AI service categories: Intelligent Automation, Data Management, Machine/Deep Learning, and Natural Language Processing. (externetworks.com) |
| Disaster recovery | A written plan plus restores that are performed and timed. More than 30 ransomware incidents handled in three years, every one recovered. | Their managed disaster recovery page states that solution auditing, failover testing and regular testing of the DR deployment are part of the service, along with automated runbooks and 24/7 monitoring of the DR solution. (extnoc.com) |

(extnoc.com) |
| Response commitments | Written into the agreement rather than implied on the website. | Their SLA-based services page states that SLAs can be tailored to the client's business requirements and lists the metric types that can be included. (extnoc.com) |
| Proof before you commit | A free Tier 1 external penetration test. The findings are yours whether or not you hire us. | Their site assessment services page states that cost varies by scope, property size and complexity, with hourly or fixed pricing. (extnoc.com) |
| Where they are | One office, in Brooklyn. On-site coverage across the New York metro, Long Island, the Hudson Valley, New Jersey, Connecticut, Pennsylvania, Maryland, Delaware and Florida, and remote delivery anywhere in the US. | Their site footer lists seven office addresses across the US and Canada: Piscataway NJ (listed first), Long Island City NY, Richardson TX, Redmond WA, Toronto ON, and Pasadena and Carlsbad CA.

Four more things worth knowing about ExterNetworks
Size and history
- Their about page states the company has operated since 2001 and publishes a headcount of more than 500 full-time employees plus over 1,000 field technicians. (extnoc.com)
NetSys: Independent since 1998. One office, in Brooklyn, and no private equity owner behind the name.
Industries they name
- Their home page names six industries in an "Industries We Serve" section: Education, Oil and Gas, Finance, Healthcare, Homeland Security, and Manufacturing & Distribution. (extnoc.com)
NetSys: Twenty six industries with a page each, from healthcare and legal to hedge funds, auto dealers and government contractors.
Compliance work published
- Their home page names SOX, HIPAA and PCI DSS as compliance frameworks their NOC services support. (extnoc.com)
- Their about page names two certifications the company itself holds: ISO 27001:2022 and SOC 2. (extnoc.com)
NetSys: Nine frameworks with a service page each: HIPAA, CMMC 2.0, SOC 2, NIST CSF 2.0, NYDFS 23 NYCRR 500, NY SHIELD, FTC Safeguards, PCI DSS and GLBA.
Rates on the website
- They publish a starting price on a public pricing and ROI calculator page, alongside an interactive calculator that compares current in-house infrastructure costs against their managed service fees. (extnoc.com)
NetSys: We do not publish rates. We quote per business rather than per seat, after a call, because a thirty person firm with two servers and a thirty person firm with a regulator are not the same job.
What we looked for on their site and could not find
privileged access, privileged identity management or managed credentials.
That means we did not find it published, not that it does not exist. Ask them directly, and ask us the same questions. If ExterNetworks publishes any of this and we missed it, write to info@netsysgroup.com and we will add it.
The honest fit: is NetSys the right ExterNetworks alternative?
When ExterNetworks is the better choice
Choose ExterNetworks if your problem is coverage. Campuses, energy sites, manufacturing plants and distribution centers that need a technician dispatched somewhere far from head office are what a thousand field technicians and seven offices exist for. The same holds if you have internal IT and want a certified operations center watching the network overnight instead of a full outsourcing arrangement. Their own ISO 27001 and SOC 2 certifications also matter to a procurement team.
When NetSys is the better choice
NetSys fits when the whole environment needs one owner. Cybersecurity, a help desk, PAM and PIM, AI adoption work and recovery planning arrive in a single monthly agreement, with a named account manager who hands out a real cell number and 24/7 monitoring behind him. Terms run month to month with no early exit penalty, and the first external penetration test is free with the findings yours either way.
NetSys and ExterNetworks: FAQs
Is ExterNetworks the same as a managed IT provider for a small office?
Not quite the same thing. ExterNetworks publishes managed services organized around network operations, communication, data analytics, security as a service and build as a service, with a field technician bench and an ITIL-certified operations team behind it. That is built for scale and for augmenting internal teams. A twenty-person office in New Jersey usually wants one provider owning everything from the firewall to the laptop, which is the shape NetSys sells. The two service pages read very differently, and that difference is the useful signal.
What is a good ExterNetworks alternative for a New Jersey business?
The answer turns on whether you need coverage or ownership. If you want a network operations center and dispatch capacity behind your own IT staff, compare them against other national operations providers. If you want one firm owning security, help desk, privileged access, recovery and AI adoption under a single agreement, NetSys covers all of New Jersey on site from Brooklyn, with no term to sign up for. The quick test: count your locations, then count the IT people you already employ.
What contract terms should we compare?
Compare four things: term length, notice period, what happens at renewal, and what leaving costs. On their side we found a terms and conditions page in the footer, but it governs use of the website rather than the service, so the contract answer will arrive with a proposal instead. NetSys states its position in public and holds to it: month to month, leave any time, no early exit penalty, with the response commitments carried in the same agreement. That is the whole answer, not a summary of a longer one.
How do the two firms handle disaster recovery testing?
Both put testing in writing, which is more than the category norm. ExterNetworks publishes failover testing, solution auditing and regular testing of the recovery deployment as part of their managed disaster recovery service, with automated runbooks behind it. NetSys writes the plan, then performs and times restores, so the recovery target is a measured number rather than an intention. If recovery is why you are shopping, ask both firms for the date of the last successful restore and how long it took.
