NetSys vs. Corsica Technologies
Corsica is one of the more interesting national MSPs because, like us, they lead with security rather than bolting it on. The comparison here is between two security-first firms with different second acts: theirs is data integration, ours is AI engineering.
The short answer
Corsica and NetSys both lead with security. Corsica's second specialty is EDI and data integration; NetSys's is an in-house AI and software practice. Match the specialty to your actual problem. Terms at NetSys are month to month.
What Corsica Technologies is
Corsica Technologies dates to 1995 and now runs from Greenville, South Carolina with offices around the country. They deliver managed IT and cybersecurity to mid market and enterprise clients, hold a genuine specialty in EDI and data integration that most MSPs cannot offer, and expanded again in late 2025 by acquiring AccountabilIT, which pushed them past a hundred thousand protected endpoints.
Two security-first firms, two specialties
Corsica's differentiator is EDI and data integration. Ours is an in-house AI and software practice: readiness assessments, Copilot rollouts done tenant-first, workflow automation, custom Microsoft Graph connectors with scoped permissions, and full custom builds like the hedge fund CRM in our published case studies. Match the specialty to the problem you have.
The base agreement
Everything we consider core ships in one monthly fee: cybersecurity, engineer-answered helpdesk, privileged access management, privileged identity management, disaster recovery planning with restores performed and timed, and the AI practice. Month to month. The industry's standard remains a multi-year auto-renewing term, so read any quote, theirs or ours, with the exit terms in hand.
Size and attention
A hundred thousand endpoints is real scale, and scale has real uses. NetSys stays deliberately small enough that the engineers who know your environment are the ones who answer for it, with an account manager whose cell number you carry. For a mid sized business, that attention is usually worth more than a bigger roster.
What each of us publishes
Their column is quoted from pages on their site 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 | Corsica Technologies | |
|---|---|---|
| Agreement | Month to month. Leave any time, no early-exit penalty. | Their FAQ page states that agreements auto-renew for a similar term unless termination is requested at least 60 days before the end of the initial or any subsequent term, and refers to a three-year partnership period. (corsicatech.com) |
| What the monthly fee covers | One agreement: AI services, cybersecurity, managed IT with help desk, PAM, PIM and disaster recovery planning. | Their managed IT support page lists help desk and end-user support, cybersecurity management, cloud services and workspace management, network and VoIP services, patch management, device management, backup and disaster recovery, hardware as a service (HaaS), IT compliance services, vendor and procurement management, and database and application support. (corsicatech.com) |
| AI and automation | In-house practice led by Jamie Baum: readiness assessments, Copilot rollouts, custom agents and workflow automation. | Their AI consulting page publishes an AI practice branded "Corsica AI One" covering strategic planning, data platform setup and integration, data security and risk assessment, AI governance consulting, agentic AI consulting, implementation and integration, and employee training and enablement, and separately promotes Microsoft Copilot training and consulting. (corsicatech.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 backup and disaster recovery page lists hybrid local plus cloud backups, daily desktop-level backups, bare metal backups, and cloud service backups for Azure, Microsoft 365, Dropbox and Google Workspace, and states multiple backups per day, AES 256-bit encryption, replication in bicoastal SOC 2 Type 2 certified data centers, and server backup validation on regular intervals. (corsicatech.com) |
| Who answers | A NetSys engineer, plus a named account manager who gives you a real cell number. | Their IT compliance services page states that every client receives a dedicated virtual CIO who helps build a three-year technology roadmap, and that their cybersecurity staff are in-house. (corsicatech.com) |
| Response commitments | Written into the agreement rather than implied on the website. | Their managed IT support page publishes a four-tier priority table with assign-within, respond-within and minimum-communication targets: Critical 15 minutes / 30 minutes / 2 calls per day; Urgent 30 minutes / 1 hour / 1 call per day; Standard 2 hours / 4 hours / 1 call per day; Low 4 hours / 8 hours / 1 email per day. (corsicatech.com) |
| Proof before you commit | The free assessment is a remote external penetration test, limited to the information available to NetSys and the external scope we agree with you. | Their penetration testing page links to a sample penetration test report, and their IT compliance page offers a complimentary HIPAA readiness assessment. (corsicatech.com) |
| Where they are | One office, in Brooklyn. On-site across New York City, Long Island, Westchester, the Hudson Valley, North Jersey and Fairfield County, CT, with remote managed IT nationwide. | Their office locations page lists five offices with full street addresses (Fort Wayne IN, Greenville SC, Little Rock AR, Scottsdale AZ, Colorado Springs CO) and a further set of cities under "Other Locations" given with city and ZIP only, and states they serve businesses throughout the United States and Canada.

Industries they name
- Their site navigation names accounting, banking, construction, criminal justice, finance, government, healthcare, law firms, manufacturing, nonprofits, oil and gas, private equity firms, schools and education, and sustainable business as industries served. (corsicatech.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 IT compliance services page names CMMC, HIPAA, NIST, PCI-DSS, CJIS, SOC 2, ISO 27001, GLBA, GDPR and FedRAMP among the frameworks it addresses. (corsicatech.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
- Their pricing calculator page cites a general market range for MSP pricing rather than their own rates, and requires name, email and company details before the calculator can be accessed. (corsicatech.com)
NetSys: We do not publish rates. We price per user per month and quote each business after a call, because a thirty person firm with two servers and a thirty person firm with a regulator are not the same job.
The honest fit: is NetSys the right Corsica Technologies alternative?
When Corsica Technologies is the better choice
Choose Corsica if EDI or heavy data integration sits at the center of your operations, or you want a security-led national provider at six-hundred-person scale with offices around the country.
When NetSys is the better choice
Choose NetSys if your second problem after security is workflow: hours lost to intake, reporting, phones and re-keying that an in-house AI practice can engineer away, all inside one month to month agreement.
NetSys and Corsica Technologies: FAQs
Both firms call themselves security-first. How do we compare that claim?
Ask for the same evidence from both: what the security stack includes in the base fee, whether privileged access management is standard, how incidents get staffed overnight, and what recovery looks like in practice. Our published record includes a 100 percent ransomware recovery rate across clients and a case study restoring a restaurant group in 4.5 hours. Collect the equivalents and compare.
We do not use EDI. Does Corsica's specialty matter to us?
Only as a signal of fit. Specialties show where a provider invests its engineering. If your operations run on EDI, theirs is a real advantage. If your operations lose hours to manual workflow, intake, reporting and phones, that is what our AI practice exists to engineer away, and it is included rather than sold as a project.
What does moving to NetSys involve?
The same deliberate transition we run for every takeover: documentation and credential handover, backup verification before cutover, parallel monitoring until nothing is dark. Month to month terms from the first invoice, so the burden of keeping you stays on us.
