How cybersecurity is delivered in Austin
Austin 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 Austin include Spectrum Business, AT&T Business Fiber and Google Fiber; availability, routing and installation dates must be verified at your address before a failover design is approved.
Who cybersecurity in Austin is built for
Businesses we can support in and around Downtown Austin, the Domain, East Austin, Round Rock and Cedar Park include technology and professional firms on Rippling, medical practices on athenahealth, real estate firms on AppFolio, law firms on Clio, semiconductor and hardware suppliers on Epicor, and nonprofits on Bloomerang. 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 Austin 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 Austin: what NetSys delivers

A 45-person nonprofit organization in East Austin
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 nonprofit organization in East Austin with 45 staff, client data in Bloomerang and five permanent Global Administrators in the tenant. An auditor asked for a written incident response plan and there is not one. There is no multifactor authentication on three of the admin accounts, a former employee's login is still active, the backups have never been restored, and a written incident response plan does not exist.
- 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
- 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
- Standing administrator rights converted to just-in-time roles through Entra ID Privileged Identity Management, with break-glass accounts kept outside it
- 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
- A written incident response plan with named owners, the insurer's hotline and counsel's contact, tested on a tabletop exercise
- Vendor questionnaire answered from the documented controls, with the evidence attached rather than promised
Every device is watched by a team that responds, every account sits behind multifactor authentication and Conditional Access, email authentication reduces unauthorized use of the domain and the backups restore. The questionnaire gets answered from documentation. Month to month, like every NetSys agreement.
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 Austin: 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.

What cybersecurity costs in Austin
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 Austin: FAQs
What is managed detection and response, and do we need it?
MDR puts an EDR agent on every device and a 24/7 team behind it that isolates a compromised machine and investigates, rather than an antivirus that quarantines a file and moves on. Cyber insurers now ask for it by name, which is the practical reason most businesses in Austin end up with it.
Can you work alongside our internal IT person?
Yes. In a co-managed arrangement your person keeps the day-to-day and we run monitoring, the security stack, vulnerability management and after-hours response, with the split written into the agreement.
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.
Do you have an office in Austin?
Our office is in Brooklyn, NY. Austin 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.
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.
