Cybersecurity Services in Maryland
Security operations for Maryland organizations, from federal subcontractors near Fort Meade and life sciences suppliers along I-270 to practices on the Eastern Shore: managed detection and response on every device, identity and email protection, vulnerability scanning, backups proven by restores, and incident response that keeps Maryland and federal deadlines in view. Delivered remotely from Brooklyn, with agreements that run month to month.
The short answer
NetSys provides managed cybersecurity to businesses across Maryland: ThreatDown managed detection and response on every device, Microsoft Defender and Entra ID Conditional Access in Microsoft 365, Barracuda email protection, Rapid7 vulnerability scanning, KnowBe4 training, tested immutable backups and incident response. It is remote by design, delivered from our Brooklyn office, so a firm in Frederick, Annapolis or Salisbury gets the same coverage as one in Baltimore. Monitoring and emergency service run 24/7, the help desk is staffed seven days a week from 4 a.m. to 11 p.m. Eastern time, on-site visits are arranged in advance, and agreements run month to month.

Contractors around Fort Meade, Aberdeen and Pax River
Maryland's defense work is spread across the state. Fort Meade in Anne Arundel County houses NSA, U.S. Cyber Command and the Defense Information Systems Agency; the Johns Hopkins Applied Physics Laboratory is among Howard County's largest employers; Aberdeen Proving Ground anchors Harford County; and Naval Air Station Patuxent River draws aerospace contractors to St. Mary's County. The smaller firms supporting these programs, including engineering shops, software teams and staffing companies, often handle controlled unclassified information for a prime. That brings contract clauses with deadlines attached: NIST SP 800-171 controls, a current score in the Supplier Performance Risk System and a report to the Defense Department within 72 hours of discovering a cyber incident. What these firms need from a security provider is proof as much as protection: logs kept long enough to reconstruct an incident, access limited to the right people and devices, and records that match how the systems actually run.
Research, health care and Annapolis
Along I-270, Montgomery County holds NIH, FDA and NIST alongside AstraZeneca, and Frederick County adds Fort Detrick, the Frederick National Laboratory and life sciences companies such as Kite, Lonza and Thermo Fisher Scientific. Labs, contract research groups and suppliers in their orbit guard unpublished data and processes, and partners often vet their security before a contract is signed. Health care runs statewide, from large systems such as Johns Hopkins, the University of Maryland Medical System and Adventist HealthCare to independent practices and home-care agencies holding patient records. Annapolis, the state capital, is home to associations, law and consulting firms and state vendors that handle sensitive correspondence. Around all of them are the smaller companies of the Eastern Shore, Western Maryland and the suburbs, which need the same core protections: accounts that resist phishing, devices that report compromise and backups that restore.
How remote delivery works across a long state
The nearest corner of Maryland, Elkton in Cecil County, is about 140 miles from our Brooklyn office, roughly two and a half hours by car. Rockville, Frederick and Salisbury are around four hours away, and Garrett County in the far west is more than 350 miles off, six hours or more. Security operations do not depend on that distance. Monitoring runs 24/7, and containment is remote: an engineer can isolate an infected laptop from the ThreatDown console, revoke sessions and reset credentials in Microsoft 365, and block traffic at a managed firewall without anyone traveling. The help desk is staffed seven days a week from 4 a.m. to 11 p.m. Eastern time, and emergency service is available 24/7. Visits for a firewall installation or a network change are arranged in advance and scoped in the proposal, with travel stated in writing.
Areas we cover across Maryland
One set of terms covers the whole state: Baltimore and Towson; the I-270 corridor from Bethesda and Rockville to Gaithersburg and Frederick; Columbia, Annapolis and the Fort Meade area; Southern Maryland around Lexington Park and Waldorf; the Eastern Shore from Elkton and Easton down to Salisbury and Ocean City; and Hagerstown and Cumberland in the west. All of it sits outside the New York area regions where we work on site, so every Maryland engagement is remote-first. Agents, policies and backup jobs are deployed over the network, firewalls and laptops can ship pre-configured, and any visit is agreed ahead with its travel stated in writing. A company near Washington, D.C. gets the same arrangement as one near the Delaware line.

A 40-person engineering subcontractor near Fort Meade
This planning example shows how we could scope the work. It is not a claim about a customer in this market or a measured result. For published customer work, see our case studies.
An engineering subcontractor with 40 staff in Howard County supports a prime on a defense program and receives drawings marked as controlled unclassified information. The files sit on a shared drive anyone can open, several engineers use personal laptops, and the company's SPRS score was entered two years ago by an employee who has since left. The prime has sent a flow-down reminder, and nobody knows who would file a DFARS incident report.
- Traced where the controlled drawings arrive, where they are stored and who opens them, then set a boundary around them
- Moved the drawings into a restricted enclave open only to named engineers on enrolled, encrypted laptops with multifactor sign-in
- Deployed ThreatDown MDR on every company device and took personal laptops out of engineering work
- Started Rapid7 InsightIDR log collection, with retention long enough to reconstruct an incident months later
- Wrote an incident plan naming who reports to DoD within 72 hours and who holds the medium assurance certificate
- Organized evidence of the implemented controls so the company can redo its NIST SP 800-171 self-assessment and SPRS entry
The company can show where its controlled information lives and who can reach it, and its next self-assessment will match the systems it really runs. If something goes wrong on a weekend, the people, the certificate and the 72-hour clock are already written down. The agreement runs month to month.
Seven-location BBQ restaurant group
Our ransomware recovery case study covers a seven-location restaurant group in the Southwest that had paid a ransom after an earlier attack. When attackers struck again on a Saturday with a 7-Bitcoin demand, the group was fully restored in 4.5 hours with all of its data recovered and no ransom paid. It is not a Maryland engagement. We point to it because it shows what tested backups and a practiced recovery change when an extortion demand arrives.

MODPA, DFARS and where CMMC stands
The Maryland Online Data Privacy Act (Md. Code, Com. Law § 14-4701 et seq.) took effect October 1, 2025 and reaches processing from April 1, 2026. It covers organizations that do business in Maryland or target its residents and, in the prior calendar year, controlled or processed personal data of at least 35,000 consumers (excluding payment-only data), or of at least 10,000 while earning more than 20 percent of gross revenue from selling it. Duties include collecting only what is reasonably necessary, never selling sensitive data, keeping reasonable administrative, technical and physical security, and documenting assessments of high-risk processing. Defense contractors holding covered defense information also answer to DFARS 252.204-7012: NIST SP 800-171 controls and a report to DoD within 72 hours of discovering a cyber incident. CMMC Phase II, due November 10, 2026, was suspended on July 13, 2026; Phase I self-assessments still apply. Applicable duties depend on the business, its data and its contracts, and your legal or compliance adviser decides which apply.

How security services are priced in Maryland
Ongoing security is priced per user per month, and an assessment or remediation project is quoted separately. In Maryland the cost drivers are usually the number of devices and identities in scope, whether your contracts call for federal safeguarding evidence or a separate enclave for controlled information, whether privacy law or client questionnaires require documented assessments, how much cleanup comes before monitoring starts, and whether your Microsoft licensing already includes Business Premium security features. Planned visits add travel from Brooklyn, stated in writing. The free external penetration test comes first and costs nothing.
Who this fits, and who it does not
Best fit: Maryland organizations with regulated data, contract security clauses or enough money moving that a breach would hurt, and no security team of their own: defense subcontractors, life sciences suppliers, practices, financial and professional firms and nonprofits. An internal IT person can stay in charge under a co-managed split.
Not a fit: companies that want a product installed and forgotten, or that need a certified CMMC assessor. We implement and document controls but are not a C3PAO, and the service changes daily habits for admins, finance staff and vendors, with monthly reviews.

Cybersecurity in Maryland: FAQs
Does the Maryland Online Data Privacy Act apply to my business?
It can, even for a company based in Virginia, Delaware or D.C.: MODPA asks whether you do business in Maryland or target its residents. The main test is personal data of 35,000 or more Maryland consumers in the prior calendar year, excluding payment-only data, or 10,000 if selling data brings in over 20 percent of gross revenue. Nonprofits are not exempt as a group. Counsel confirms coverage; we implement and document the security practices the Act requires.
Where does CMMC stand for Maryland defense contractors?
As of late September 2026, CMMC is paused in Phase I. On July 13, 2026 the Pentagon suspended Phase II, which would have required third-party Level 2 certification from November 10, 2026, and began a program review. Phase I self-assessments, SPRS scores, annual affirmations and DFARS 252.204-7012 still apply, including the 72-hour incident report, and select government-led assessments continue. We implement and document the controls, we are not a C3PAO, and your contracts manager confirms which clauses you hold.
How do you handle an incident at a site hours from Brooklyn?
Remotely first, because that is quickest. Emergency service is available 24/7, and an engineer can isolate a device through ThreatDown, end sessions and reset credentials in Microsoft 365 and block traffic at a managed firewall without traveling. We then build the timeline your counsel and insurer will ask for. If hands are needed on site in Frederick, Salisbury or anywhere else in the state, for example to replace hardware, the visit is arranged with you and the travel stated in writing.
What hours is the help desk staffed?
The help desk is staffed seven days a week from 4 a.m. to 11 p.m. Eastern time. Monitoring runs 24/7, so a ThreatDown alert at 3 a.m. is acted on rather than queued, and emergency service is available 24/7. Routine requests, such as adding a user or changing a mailbox permission, are handled during staffed hours. All of Maryland shares our Eastern time zone.
What does the free external penetration test include?
It is a remote test of what your business exposes to the internet. It covers only the scope we agree with you in writing and uses only information NetSys has available, and the report states each finding with the limits of the test. Your internal network, Microsoft 365 tenant, devices and backups are reviewed only under a separate scope. Many engagements begin with this test before any monthly service is proposed.
See what an attacker sees before they do.
The free assessment is a remote external penetration test, limited to the information available to NetSys and the external scope we agree with you. Internal reviews and ongoing security management are scoped separately.
