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.

Industries we serve

Built for Long Island's core industries

Long Island has a business base most people outside it underestimate: major health systems, a defense and aerospace supply chain with deep roots, a large manufacturing sector, and the financial and professional firms clustered in Nassau County.

Defense & aerospace contractors

Suppliers in the DoD supply chain across Suffolk and Nassau validating NIST SP 800-171 controls and CUI segmentation ahead of CMMC Level 2.

Health systems & medical groups

Island-based hospital networks, physician groups, and health tech meeting HIPAA and the NY SHIELD Act.

Manufacturing & industrial

Hauppauge, Melville, and Farmingdale manufacturers securing production networks, connected equipment, and supplier integrations.

How we test each sector, with the frameworks and prices that apply: penetration testing by industry, including fintech, law firms, healthcare, and SaaS.

On the ground in Long Island

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 page
02Can 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 testing
03Do 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 testing
05Can 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 testing
06How 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.
