How cybersecurity is delivered in Maryland
Baltimore is about three and a half hours from Brooklyn and Montgomery County four, so day-to-day work is remote and on-site visits are planned rather than dispatched same-day. 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. On-site commitments outside the tri-state area are arranged in advance and sized to the engagement: a mostly remote engagement needs no dedicated on-site engineer, while an engagement that calls for regular presence, such as vCISO work with someone on site two days a week, can include a dedicated engineer with a drive time generally under an hour once availability, location and the visit schedule are confirmed in the proposal. Hardware can ship pre-configured where the project permits remote setup. Confirm landlord access, circuit diversity, cabling and equipment space before approving a network change. Carrier options to check in Maryland include Verizon Fios, Comcast Business and Lumen; availability, routing and installation dates must be verified at your address before a failover design is approved.
Who cybersecurity in Maryland is built for
Businesses we can support in and around Baltimore, Columbia, Bethesda, Rockville and Annapolis include defense and intelligence contractors on Deltek Costpoint, medical practices on Epic, biotech companies along I-270 on Benchling, professional firms on QuickBooks Online, nonprofits on Blackbaud, and contractors on Procore. These are examples of business and application needs, not a list of local clients. We coordinate infrastructure, identity and integration with the application vendor, and identify any compliance requirements during discovery. Companies with an internal IT person can agree a split of responsibilities, systems and coverage hours before work begins.
Continuity planning for your Maryland business
Start with the systems your team cannot work without. Record the impact of a building power outage, a failed internet circuit, a compromised account and an unavailable application vendor. Then agree recovery priorities, an independent access path, protected backup copies and a test for each critical workflow. Controls reduce particular risks; they do not guarantee that an incident cannot happen.
Cybersecurity in Maryland: what NetSys delivers
Detection and response
- ThreatDown managed detection and response with EDR agents on every workstation, laptop and server, monitored 24/7
- Microsoft Defender for Business and Rapid7 InsightIDR telemetry from identities, email and endpoints, with a person acting on alerts
- Isolation of a compromised device in real time, with an engineer on the case rather than a ticket in a queue
- Incident investigation and a written timeline for leadership, counsel and your insurer
Identity and email
- Entra ID Conditional Access and multifactor authentication across Microsoft 365, with legacy authentication switched off
- Privileged access and privileged identity management so admin rights are granted just in time and removed afterwards
- Barracuda Email Protection in front of every mailbox, with SPF, DKIM and DMARC enforced
- KnowBe4 security awareness training with simulated phishing built from the lures your industry receives
Exposure and recovery
- Rapid7 InsightVM vulnerability scanning on a schedule, with findings fixed rather than filed
- Cisco Meraki or Fortinet firewall management, segmentation and DNS filtering on office and remote devices
- Immutable backups through Datto SIRIS or Veeam, with restores tested and documented
- The free remote external penetration test, limited to available information and the external scope agreed with you
A 26-person nonprofit organization in Baltimore
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.
A 26-seat nonprofit organization in Baltimore that handles regulated data in Blackbaud across the office and remote staff on home Wi-Fi. The cyber insurer asked for evidence of MFA and endpoint detection before renewal, and nobody has it. Email protection is whatever Microsoft ships by default, DMARC was never set up, the Lumen firewall is a consumer router, and the last security training anyone remembers was a poster.
- Monthly review of dormant accounts, forwarding rules, consent grants and administrator assignments, reported in writing
- Microsoft 365 investigation: sign-in logs, forwarding rules and consent grants reviewed to establish whether a mailbox was compromised, then multifactor authentication and Entra ID Conditional Access enforced for every account
- Rapid7 InsightVM deployed for scheduled vulnerability scanning, with the first month's findings prioritized and closed
- Datto SIRIS backups with immutable cloud copies for the servers and a Microsoft 365 backup for the tenant, with a restore tested and the result written down for the insurer
- Rapid7 InsightIDR collecting identity, email, endpoint and firewall logs so an intrusion is visible in one console
- Keeper password management deployed and shared credentials rotated, starting with the ones in the spreadsheet
The insurer's questions get answered with evidence instead of assurances, wire instructions have a verification step that does not depend on memory, and an engineer is watching the tenant at night. The business gets one person to call. The agreement stays month to month.
Firewall, antivirus and maintenance for a five-person office
A five-person office needed the basics done properly rather than an enterprise stack. NetSys replaced the internet provider's router with a business-grade firewall configured with sensible rules, secure remote access and logging, deployed managed antivirus on every machine with updates and alerts handled centrally, and put patching, backup checks and health reviews on a schedule. The agreement covers what the office needs and nothing it does not, month to month. No outcome figures were measured for publication.

Compliance in Maryland: Maryland’s PIPA and what sits on top of it
The Maryland Personal Information Protection Act (Com. Law § 14-3504) requires a reasonable, prompt investigation after discovery or notification of a covered breach. Resident notice depends on the likelihood of misuse, and required notice to the Attorney General precedes resident notice. The service scope should identify the records, access controls, retention settings and incident evidence your business needs; your legal or compliance adviser determines which requirements apply. The security service is built to produce the evidence those rules ask for: multifactor authentication and Conditional Access reports, endpoint detection coverage, vulnerability scan results, backup restore records and a tested incident response plan. Discovery identifies missing records and assigns the documentation work. Applicable duties depend on the business, data, exemptions and contracts; your legal or compliance adviser determines which requirements apply.

What cybersecurity costs in Maryland
Cybersecurity is priced per user per month when it runs as an ongoing service, and per project for an assessment or a remediation. What moves the number: how many devices and identities are in scope, how much incident remediation and recovery is needed beyond the monitoring and authorized MDR actions in scope, which compliance standard the evidence has to satisfy, and whether the Microsoft 365 tenant is already on Business Premium or the security tooling comes from us. The free external penetration test costs nothing and runs remotely before any of that. Our managed IT pricing page explains how the fee is built.
Who this fits, and who it does not
Best fit: businesses with enough people, money movement or regulated data that a breach would hurt, and no security team of their own: professional practices, healthcare groups, importers, financial firms, nonprofits and agencies holding client credentials. Companies with an internal IT person fit as a co-managed arrangement.
Not a fit: organizations that want a security product installed and left alone. The service is monitored, reviewed and reported monthly, and it changes the way administrators, finance staff and vendors work. If that is not wanted, a tool purchase serves better than an engagement.

Cybersecurity in Maryland: FAQs
Do we need a security assessment before signing up?
The free external test is where most engagements start. A fuller assessment of the tenant, devices, network and backups is scoped separately and produces a prioritized fix list that becomes the first ninety days of the service.
What does the free external penetration test include?
The free offer is a remote external penetration test, limited to the information available to NetSys and the external scope agreed with you. It examines what your business shows the internet and reports the findings with their scope and limitations stated. Reviews of tenant settings, devices, internal networks or backups need a separate scope.
Will cybersecurity services help us pass a cyber insurance questionnaire?
Yes. Multifactor authentication, endpoint detection and response, tested offline backups and security awareness training are the four controls almost every questionnaire asks about, and the service produces the evidence for each. Our cyber insurance readiness page lists what carriers are asking for in 2026.
Do you have an office in Maryland?
Our office is in Brooklyn, NY. Baltimore is about three and a half hours from Brooklyn and Montgomery County four, so day-to-day work is remote and on-site visits are planned rather than dispatched same-day. Outside the tri-state area the on-site arrangement is agreed before the engagement starts and sized to what it needs: none for a mostly remote account, or a dedicated engineer where regular presence such as vCISO work with someone on site two days a week is part of the scope. A drive time generally under an hour is an option subject to confirming engineer availability and your address. The help desk is staffed seven days a week from 4 a.m. to 11 p.m. Eastern time, with emergency service 24/7. The proposal states the on-site arrangement and any travel in writing, and the agreement runs month to month.
How can IT support help with Maryland data-security requirements?
The Maryland Personal Information Protection Act (Com. Law § 14-3504) requires a reasonable, prompt investigation after discovery or notification of a covered breach. Resident notice depends on the likelihood of misuse, and required notice to the Attorney General precedes resident notice. NetSys can help document the relevant systems, controls and incident evidence within an agreed scope; legal notification decisions remain with your authorized business and legal team.
