Cybersecurity Services in Dallas
NetSys provides cybersecurity services to businesses in Dallas: 24/7 managed detection and response on every device, identity and email protection across Microsoft 365, vulnerability scanning, staff training and immutable backups, with an engineer acting on alerts rather than forwarding them.
The short answer

How cybersecurity is delivered in Dallas
Dallas is served from Brooklyn, one hour behind us on Central time. 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 (3 a.m. to 10 p.m. Central), seven days a week. The proposal states severe-incident escalation, authorized remediation and any other after-hours work. On-site commitments outside our on-site coverage (New York City, Long Island, Westchester, the Hudson Valley, North Jersey and Fairfield County, CT) 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 Dallas include AT&T Business Fiber, Spectrum Business and Frontier Fiber; availability, routing and installation dates must be verified at your address before a failover design is approved.
Who cybersecurity in Dallas is built for
Businesses we can support in and around Uptown, the Design District, Plano, Las Colinas and Frisco include financial and insurance firms on Salesforce Financial Services Cloud, commercial real estate firms on Yardi Voyager, medical practices on eClinicalWorks, law firms on NetDocuments, logistics and distribution companies on Manhattan Active, and professional firms on QuickBooks Online. 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 Dallas 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 Dallas: what NetSys delivers

- Rapid7 InsightIDR or Microsoft Sentinel collecting identity, email, endpoint and firewall logs so an intrusion is visible in one place
- Written incident response plan with named owners, tested once a year on a tabletop exercise
- Post-incident reports written for your insurer and your counsel, not just your IT team
Harden the tenant and the people

A 40-person real estate business in Uptown
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 40-person real estate business in Uptown whose Microsoft 365 tenant was set up years ago and never hardened, running Yardi Voyager and moving money by wire every week. The cyber insurer asked for evidence of MFA and endpoint detection before renewal, and nobody has it. Nobody can say whether a mailbox was compromised or the sender was spoofed, the antivirus came bundled with the laptops, and the firewall the last provider installed has a vendor port open that nobody remembers approving.
- Standing administrator rights converted to just-in-time roles through Entra ID Privileged Identity Management, with break-glass accounts kept outside it
- KnowBe4 rolled out with a baseline phishing test in week one and training on a recurring schedule, aimed at the lures the industry actually receives
- Vendor questionnaire answered from the documented controls, with the evidence attached rather than promised
- Free remote external penetration test limited to information available to NetSys and the external scope agreed with the business; internal review and remediation scoped separately
- Barracuda Email Protection placed ahead of the mailboxes and SPF and DKIM alignment checked, with DMARC reporting and staged enforcement to reduce unauthorized use of the domain, with a callback rule adopted for any change in payment instructions
- Cisco Meraki firewall installed with intrusion prevention, geo-blocking, segmentation between finance, servers, printers and guests, and DNS filtering on every device
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 Dallas: Texas’s breach-notification statute and what sits on top of it
Texas Business and Commerce Code § 521.053 requires qualifying breaches affecting 250 or more Texans to be reported to the Attorney General, alongside applicable consumer notices. The Attorney General provides an electronic reporting process and explains the information required from an authorized representative. 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.
Primary sources
What cybersecurity costs in Dallas
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 Dallas: 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 Dallas?
Our office is in Brooklyn, NY. Dallas is served from Brooklyn, one hour behind us on Central time. Outside our on-site coverage 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 (3 a.m. to 10 p.m. Central), 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 Texas data-security requirements?
Texas Business and Commerce Code § 521.053 requires qualifying breaches affecting 250 or more Texans to be reported to the Attorney General, alongside applicable consumer notices. The Attorney General provides an electronic reporting process and explains the information required from an authorized representative. 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.

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.
