How cybersecurity is delivered in Charlotte
Security work for Charlotte organizations is remote by nature, and that is a strength rather than a compromise: the attack arrives over the internet, and so does the response. ThreatDown agents on each device report to a monitoring team that can isolate a machine from the network, stop a process and roll back changes without touching the hardware. In Microsoft 365 we revoke sessions, reset credentials and block a sign-in country from Brooklyn as quickly as from a desk next to yours. NetSys does not send engineers to Charlotte; if a device must be reimaged, it is rebuilt remotely through Intune or a replacement ships enrolled. Firewalls are managed remotely as well, with configuration backups kept so a replacement can be loaded before it leaves our office. 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.
What Charlotte firms are defending against
Business email compromise usually starts with one phished account. For Charlotte companies that move money or sit in a bank's supply chain, the pattern is a stolen Microsoft 365 login, a quiet inbox rule that hides replies, and a changed wire or payroll instruction weeks later. Second is ransomware through an unpatched VPN or remote access tool. Third is a breach at a vendor that exposes your data from someone else's system. Our controls follow that order: phishing-resistant multifactor sign-in and Conditional Access that blocks legacy protocols, Barracuda impersonation and link protection, alerts on forwarding rules and risky sign-ins, ThreatDown on endpoints and servers, Rapid7 scans that catch exposed services, and Keeper so staff stop reusing passwords. KnowBe4 phishing tests show who needs more coaching.
What Mecklenburg County's 2017 ransomware attack teaches
In December 2017 a Mecklenburg County employee opened an email attachment that released LockCrypt ransomware, which encrypted 48 of the county's roughly 500 servers. The attackers demanded about $23,000 in bitcoin. The county refused, trusting its backups, and rebuilt over the following weeks; by December 20 about 50 of its 200 affected systems were running again. North Carolina later went further: G.S. 143-800, enacted in 2021, bars state agencies and local governments from paying a ransom or even communicating with the attackers. Private companies face no such ban, but the lesson carries over. Paying is not a plan. Backups that ransomware cannot reach, restores tested before you need them, and a written recovery order decide how long you are down.
Evidence for bank reviews, insurers and auditors
Charlotte businesses are asked to prove their security more often than most. A bank onboarding a vendor, a cyber insurer at renewal, a private equity buyer in diligence and a customer's procurement team all ask similar questions. We keep the answers current: Intune and Defender reports showing every device encrypted and compliant, Conditional Access policies, ThreatDown coverage and incident logs, Rapid7 scan trends, KnowBe4 completion rates, Keeper adoption and backup test results. Insurance applications now commonly ask about multifactor sign-in on email and remote access, endpoint detection and response, and offline or immutable backups, so those three get done first. When an application asks for a control you do not have, we say so and close the gap before anyone signs it.
The first 30 days of a Charlotte security engagement
Week one starts with the free external penetration test, run remotely within an agreed scope, and an inventory of devices, accounts, admin roles and internet-facing services. Week two deploys ThreatDown and Defender, retires the old antivirus and turns on multifactor sign-in in stages, beginning with administrators and remote access. Week three hardens Microsoft 365: legacy authentication off, Conditional Access by device and location, mailbox auditing, limits on external sharing, and Barracuda in front of email. Week four sets up immutable backups with a test restore, the first Rapid7 internal scan and a KnowBe4 baseline phishing test. You then get a written list of what is fixed, what comes next and what still carries risk, ranked so the budget goes to the biggest exposure first.
Cybersecurity in Charlotte: what NetSys delivers
Watch and respond
- ThreatDown MDR and EDR on every device, with a 24/7 team that isolates and investigates rather than emails
- Rapid7 InsightIDR or Microsoft Sentinel collecting identity, email, endpoint and firewall logs so an intrusion is visible in one place
Harden the tenant and the people
- Microsoft Defender for Business, Entra ID Conditional Access and phishing-resistant sign-in for finance staff
- Legacy authentication off, dormant accounts closed, forwarding rules and consent grants reviewed monthly
Measure and recover
- Rapid7 InsightVM scans of the internal and external footprint, with a monthly fix list
- Managed firewall with intrusion prevention, segmentation and vendor access that is logged and switched off when the work ends
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.

What cybersecurity costs in Charlotte
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.

Cybersecurity in Charlotte: FAQs
How does cybersecurity work for Charlotte organizations?
Remotely and continuously. ThreatDown and Microsoft 365 alerts reach our monitoring team 24/7, and engineers act on them: isolating a device, locking an account, blocking a sender or reversing a malicious change. The help desk is staffed 4 a.m. to 11 p.m. Eastern, seven days a week, and severe incidents go straight to your dedicated engineer at any hour. NetSys works from its Brooklyn office and has no engineers in Charlotte, so every control is chosen to be managed and fixed remotely.
What do cybersecurity services in Charlotte include, and how are they priced?
The ongoing service includes ThreatDown MDR on every endpoint, Defender for Business, multifactor sign-in and Conditional Access, Barracuda email protection, Rapid7 vulnerability scanning, KnowBe4 training, Keeper passwords and immutable backups with tested restores. It is priced per user per month after an assessment; we do not publish rates. Device and server counts, the compliance evidence you need, and whether your Microsoft 365 licenses already include the right security features move the figure. Assessments and remediation projects are quoted separately.
Do you offer a free security test for Charlotte businesses?
Yes, one: a free external penetration test. It runs remotely against your internet-facing systems, such as the firewall, VPN, email and websites, within a scope we agree in writing first, and you receive a report of what an outside attacker could find and try. It is not an internal audit or a full assessment; those are scoped and quoted separately if the test shows they are worth doing.
What should a Charlotte business do in the first hour of a ransomware attack?
Disconnect affected machines from the network but leave them powered on, do not pay or contact the attackers, and call your IT provider and your cyber insurer, since many policies set rules about which responders you use. Where NetSys runs your security, ThreatDown is designed to isolate the device automatically and an engineer takes the case. We preserve logs, find how the attacker got in, check whether data left and restore from immutable backups. NetSys has handled more than 30 ransomware incidents in three years, and every one was fully recovered.
How do North Carolina's breach rules affect a security program?
North Carolina's Identity Theft Protection Act requires notice to affected people and to the Attorney General's Consumer Protection Division after a breach of personal information, and a business storing data for someone else must alert the owner immediately. Encrypted data counts as a breach only if the key is also taken, so full-disk encryption and encrypted storage reduce what an incident costs. Good logs matter too, because they show what was and was not accessed. The notice decision belongs to your counsel. This is general information, not legal advice.
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.
