Long Island, New York
Long Island Penetration Testing Services
Invadel provides fixed-price penetration testing to Nassau and Suffolk County businesses: the health systems headquartered on the Island, the defense and aerospace contractors preparing for CMMC, the manufacturers of Hauppauge and Melville, and the financial and insurance firms of Garden City and Mineola. Senior New York testers, on-site across Long Island when your scope calls for it.
Why Invadel
Why Long Island companies test with us
Ready for the defense supply chain
Long Island still supplies the Department of Defense. We test CUI enclaves and NIST SP 800-171 controls so contractors walk into a CMMC assessment with evidence, not hope.
Fluent in healthcare compliance
Some of the largest health systems in New York are headquartered on the Island. We test clinical and patient-facing systems and report to HIPAA and the NY SHIELD Act.
A drive, not a flight
Nassau and western Suffolk are a direct trip from our Manhattan office on the LIRR or the LIE. Internal tests and readouts happen in person when that helps.

Built for how Long Island actually works
Long Island businesses are routinely underserved by New York City security firms that treat everything east of Queens as remote-only. We do not. Nassau County and western Suffolk are a direct LIRR ride or a drive out the Long Island Expressway from our Manhattan office at 1178 Broadway, which makes on-site internal network testing, facility assessments, and in-person executive readouts practical for clients from Great Neck to Hauppauge and beyond.
The Island also carries a compliance profile of its own. Its defense and aerospace suppliers are working toward CMMC Level 2 and need penetration testing that validates NIST SP 800-171 controls and proves their controlled unclassified information enclave is properly segmented. Its health systems answer to HIPAA. Its financial firms answer to NYDFS. We scope and report to each of those standards.
We serve businesses across Nassau and Suffolk, including Garden City, Mineola, Great Neck, Melville, Huntington, Hauppauge, Farmingdale, Stony Brook, Ronkonkoma, and Riverhead, on-site or remotely.

FAQ
Long Island penetration testing, answered
Common questions from Long Island teams scoping their first, or next, engagement.
Still have questions?01How much does a penetration test cost on Long Island?
Every engagement is fixed-scope and fixed-price: external network testing from $4,200, internal network testing from $6,000, and web application testing from $5,200, agreed before work begins. On-site work in Nassau or Suffolk carries no travel premium.
See the pricing page02Can you help a defense contractor prepare for CMMC?
Yes. CMMC Level 2 assessments examine whether your NIST SP 800-171 controls actually work and whether your CUI enclave is segmented from the rest of the network. We run external and internal penetration testing scoped to your assessment boundary and deliver evidence you can hand to a C3PAO.
CMMC Level 2 penetration testing03Do you come on-site to Nassau and Suffolk County?
Yes. Nassau and western Suffolk are a direct trip from our Manhattan office, so internal network testing, physical assessments, and in-person readouts are routine. Eastern Suffolk is served on-site by arrangement, and every engagement can also run remotely.
04Do you test hospitals and medical practices on Long Island?
Yes. We test the patient portals, EHR integrations, billing systems, and internal networks that hold protected health information, and report to the HIPAA Security Rule and the NY SHIELD Act for health systems, physician groups, and health tech companies across the Island.
HIPAA penetration testing05Can you test connected manufacturing equipment and IoT devices?
Yes. Hauppauge and Melville manufacturers increasingly connect production equipment to corporate networks, and defense suppliers build connected hardware of their own. We test the devices themselves, from firmware and debug ports to wireless interfaces, and the networks they sit on, with findings mapped to IEC 62443 where operational technology is involved.
Hardware and IoT penetration testing06How quickly can a Long Island engagement start?
Scoping usually takes a day, onboarding begins within 24 hours of a signed proposal, and testing typically starts within a week. Assessment and audit deadlines can often be accommodated faster; tell us the date.
