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.

All IT services in Maryland

The short answer

NetSys provides managed cybersecurity to Maryland organizations: 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, immutable backups with tested restores 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, and NetSys does not send responders on site. 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. Agreements run month to month.

How cybersecurity is delivered across Maryland

Security operations do not depend on distance, so every Maryland engagement is remote. When ThreatDown flags ransomware behavior on a laptop in Columbia, an engineer isolates the device from the console, revokes the user's Microsoft 365 sessions, resets credentials and blocks the offending address at the managed firewall, all in the same response. Evidence is collected remotely too: endpoint telemetry, Entra ID sign-in logs, firewall logs and mailbox audit records go into the incident file your counsel and insurer will ask for. NetSys does not send engineers to Maryland offices. If a machine must be replaced, a clean one ships enrolled in Windows Autopilot, and the infected device is wiped or held for forensics as counsel directs. Contacts for your insurer's breach hotline and your attorney are recorded before any incident, so the first hour goes to containment, not searching. Monitoring runs 24/7 from Brooklyn, and so does emergency service. Our staffed help-desk hours are 4 a.m. to 11 p.m. Eastern time, seven days a week. The proposal states severe-incident escalation, authorized remediation and any other after-hours work.

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 sits in Laurel, in Howard County; 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 Revision 2 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 under DFARS 252.204-7012. 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.

Attacks Maryland organizations have already lived through

Maryland has a public record of what ransomware costs. In May 2019, RobbinHood ransomware shut down systems across the City of Baltimore; the city refused to pay, and its budget office put the cost at no less than $18.2 million, counting recovery and lost or delayed revenue. In November 2020, an attack on Baltimore County Public Schools kept about 115,000 students out of remote classes while systems were rebuilt, and recovery spending passed $8.1 million over the next seven months. The Maryland Department of Health detected ransomware on December 4, 2021, and some of its services stayed down into January. In health care, MedStar Health shut its EHR and email across 10 hospitals in March 2016, and Frederick Health reported 934,326 people affected after a January 2025 attack. The pattern repeats: stolen or weak credentials, unpatched servers, flat networks and backups the attacker could reach. Those are the gaps we close first.

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.

The controls we put in place first

Most of the Maryland incidents above started with a password, so identity comes first. Every account gets multifactor sign-in, and Entra ID Conditional Access blocks sign-ins from unmanaged devices and unexpected countries. ThreatDown and Microsoft Defender for Business watch every endpoint, and alerts are acted on at any hour. Barracuda filters inbound mail, and DMARC, SPF and DKIM reduce spoofing of your domain. Rapid7 InsightVM scans for missing patches and exposed services each month, and Windows Server 2016 machines are flagged now because extended support ends January 12, 2027. Keeper replaces shared password lists, KnowBe4 runs phishing tests, and Datto SIRIS or Veeam keeps immutable copies that an attacker with administrator rights cannot delete, restored on a schedule. Over three years we have handled more than 30 ransomware incidents, and every one was fully recovered.

Published case study

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.

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.

How the monthly fee is built

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.

Cybersecurity in Maryland: FAQs

How does cybersecurity work for Maryland organizations?

It is delivered remotely, which is also the fastest way to contain an attack. Monitoring runs 24/7, so a ThreatDown alert at 3 a.m. is acted on rather than queued, and emergency service is available at any hour. The help desk is staffed seven days a week from 4 a.m. to 11 p.m. Eastern time. Ransomware and other severe events go straight to your dedicated engineer, who can isolate devices, end sessions and block traffic without traveling. NetSys does not send engineers to Maryland; replacement hardware ships preconfigured.

What do cybersecurity services in Maryland include, and how are they priced?

The service covers ThreatDown managed detection and response, Microsoft Defender and Entra ID Conditional Access, Barracuda email protection, Rapid7 vulnerability scanning, KnowBe4 training, tested immutable backups and incident response. Ongoing protection is priced per user per month, and an assessment or remediation project is quoted separately. Device and identity counts, the federal or privacy evidence your contracts require, the cleanup needed before monitoring starts and whether your Microsoft licenses include Business Premium move the figure. The free external penetration test comes first: it is remote and covers only the external scope agreed in writing.

Does the Maryland Online Data Privacy Act apply to my business?

It can, even for a company based in Virginia, Delaware or the District: the Act asks whether you do business in Maryland or target its residents. It took effect October 1, 2025, with enforcement from April 1, 2026. The main test is personal data of at least 35,000 Maryland consumers in the prior calendar year, excluding data used only to complete a payment, or 10,000 if selling data brings in more than 20 percent of gross revenue. Nonprofits are not exempt as a group, and sensitive data may not be sold. Counsel confirms coverage; we implement and document the security practices.

Where does CMMC stand for Maryland defense contractors?

On July 13, 2026 the Department of War suspended CMMC Phase 2, the third-party Level 2 certification that was to become a condition of award on November 10, 2026, and put Phases 3 and 4 on hold while a CMMC Reform Task Force reviews the program; its report, due September 11, 2026, has not been made public. Level 1 and Level 2 self-assessments, a current SPRS score and affirmation, DFARS 252.204-7012 with its 72-hour incident report and NIST SP 800-171 Revision 2 still apply. We implement and document the controls; we are not a C3PAO.

What must a Maryland business do after a data breach?

Under Com. Law § 14-3504, a business must promptly investigate whether personal information has been or will be misused. Unless it reasonably finds no likelihood of misuse, it notifies affected residents as soon as reasonably practicable and no later than 45 days after discovery, and it notifies the Attorney General's office before the residents. If 1,000 or more people are notified, the nationwide consumer reporting agencies must be told as well (§ 14-3506). Preserve logs before anything is wiped; we hold that evidence for your counsel. This is general information, not legal advice.

Start with the free test

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.
