Cybersecurity Services in Columbus, OH
Columbus has seen what a serious attack costs: the city's own network in 2024, the Ohio Lottery the Christmas before. NetSys protects central Ohio businesses with managed detection and response, hardened sign-in, email filtering, vulnerability scanning and tested backups, run remotely by engineers in Brooklyn and documented the way insurers and Ohio's safe-harbor law expect.
The short answer
NetSys protects Columbus organizations with a layered security service: ThreatDown managed detection and response and Microsoft Defender for Business on endpoints, Entra ID Conditional Access forcing multifactor sign-in, Barracuda in front of email, Rapid7 InsightVM scans, KnowBe4 phishing training, Keeper for passwords and backups an attacker cannot alter. Engineers deliver and respond remotely; NetSys does not send anyone on site in Columbus, because containment, investigation and recovery run through the same consoles. Alerts reach an engineer 24/7, staffed help desk hours are 4 a.m. to 11 p.m. Eastern, and the program is written up against a framework recognized by the Ohio Data Protection Act.

How cybersecurity is delivered to Columbus organizations
Security work is remote by design. ThreatDown agents report every suspicious process to an engineer who can isolate the laptop from the network, stop the process and collect evidence without anyone touching the machine. Sign-in policy lives in Entra ID, where Conditional Access blocks logins from unmanaged devices or unexpected countries, and Barracuda screens every message on its way into Microsoft 365. Firewalls report to their cloud consoles, and InsightVM scans the network on a schedule. NetSys does not send engineers to Columbus, so if a device has to be replaced after an incident, a clean, enrolled machine ships to the user while the old one stays quarantined. Your staff contact us the moment something looks wrong, and anything severe is escalated to your dedicated engineer without waiting in a queue. 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 the 2024 attack on the City of Columbus shows
On July 18, 2024, the City of Columbus was hit by ransomware later claimed by the Rhysida group. The city said it stopped the encryption, yet the group had already copied data and, when no ransom was paid, published about 3.1 terabytes of it. In October the city notified roughly 500,000 people that names, birth dates, addresses, bank account details, driver's license numbers and Social Security numbers may have been exposed. The lesson for private companies is that stopping encryption is not the same as stopping the attack. Modern ransomware groups steal first, so detection has to watch for unusual sign-ins and large outbound transfers, sensitive files should not sit in shares everyone can open, and an incident plan needs a communications step that does not overstate what is known.
Threats aimed at Columbus insurers, banks and clinics
Columbus concentrates exactly the data criminals want. One Columbus counts insurance and finance among the region's defining industries: Nationwide and Root lead in insurance, JPMorgan Chase employs a regional workforce of more than 18,000, and Huntington Bancshares has its headquarters downtown. Agencies, advisers, mortgage brokers and the vendors serving them become targets for business email compromise, invoice fraud and fake wire instructions. Health systems such as OhioHealth and Ohio State's medical center anchor a large practice community whose records sell well. Public bodies are targets too: the Ohio Lottery reported that 538,959 people had data exposed in the December 2023 attack that the DragonForce group claimed. Our controls follow those patterns: DMARC and impersonation filtering on email, payment-change verification by phone, phishing-resistant MFA for administrators and alerts on mailbox rules that forward mail outside the company.
Ohio's safe harbor and the insurance data security law
Two Ohio statutes shape a Columbus security program. The Ohio Data Protection Act lets a business sued in tort over a breach raise an affirmative defense when its written cybersecurity program reasonably conforms to one of the frameworks the law names: the NIST Cybersecurity Framework, NIST SP 800-171, NIST SP 800-53, the CIS Critical Security Controls or ISO/IEC 27000, while HIPAA- and Gramm-Leach-Bliley-regulated entities may conform to those rules instead. Insurance licensees answer to Revised Code Chapter 3965 as well: it calls for a written information security program and gives a licensee three business days, once it determines a cybersecurity event has occurred, to tell the Superintendent of Insurance, and licensees with fewer than 20 employees, under $5 million in revenue or under $10 million in assets are exempt from the program requirement. Our documentation maps each control to the framework you choose. This is general information, not legal advice.
The first 30 days of a Columbus security engagement
Week one establishes the baseline: we connect read-only to Microsoft 365 and Entra ID, install the NinjaOne and ThreatDown agents, run an InsightVM scan and, if you want it, our free external penetration test, which probes your internet-facing systems remotely within limits we agree first. Week two delivers findings in writing, highest risk first, each with a price. In weeks three and four, every account moves behind multifactor sign-in and Conditional Access, legacy authentication is switched off, Barracuda and DMARC go live, passwords move into Keeper, and a KnowBe4 phishing test sets the starting click rate. By day 30 a test restore has proved the backups, your incident response plan names who calls whom, and the insurer's next renewal questionnaire can be answered from records instead of guesses.
Cybersecurity in Columbus: 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
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
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
Law office: layered security on Microsoft 365 with cloud-to-cloud backup
A 25-attorney firm needed client confidences protected better than a closet server could manage. Alongside a Microsoft 365 migration, NetSys layered anti-phishing and email threat protection, DNS filtering, multifactor authentication on every account and endpoint protection across attorney devices in the office and remote, and established independent cloud-to-cloud backup of the entire tenant because the recycle bin is not a backup strategy for privileged material. The firm reported 82% fewer IT support incidents per month within two quarters.

What cybersecurity costs in Columbus
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 Columbus: FAQs
How does cybersecurity work for Columbus organizations?
Everything runs through cloud consoles watched by engineers in Brooklyn. Alerts from ThreatDown, Microsoft Defender, Entra ID and Barracuda reach an engineer 24/7, and a compromised device can be isolated within minutes without anyone traveling. NetSys does not send engineers to Columbus; clean replacement hardware ships enrolled, and evidence is collected remotely. Staff report suspicious emails or calls to the help desk, which has engineers on duty from 4 a.m. to 11 p.m. Eastern every day. Ransomware or any other severe incident goes to your dedicated engineer immediately. Terms are month to month.
How much do cybersecurity services cost in Columbus?
Cybersecurity is billed per user each month once we have assessed your environment, as a standalone service or folded into managed IT, and NetSys keeps no published rate. Headcount and device count matter, and so do the servers and cloud systems in scope, how long logs must be kept, whether an insurer, an auditor or the Ohio safe-harbor framework needs documentation, and how often you want scanning and phishing tests. One-off projects, such as hardening Microsoft 365 or writing an incident response plan, are priced on their own once scoped.
Which cybersecurity requirements apply to businesses in Columbus?
Every business holding Ohio residents' personal information falls under Revised Code 1349.19, which requires breach notice within 45 days of discovery. Following the Ohio Data Protection Act is optional; it rewards a documented program built on a recognized framework. Then come the rules for your line of work: HIPAA for practices and their business associates, Chapter 3965 for insurance licensees, SEC Regulation S-P, amended in 2024, for investment advisers and broker-dealers, NIST SP 800-171 for defense suppliers, and for tax preparers both IRS Publication 4557 and the FTC Safeguards Rule. We help work out which apply, and your counsel confirms.
What happens if we are hit by ransomware?
Phone your dedicated engineer or the help desk the moment you see it. We cut infected machines off through ThreatDown, lock the compromised accounts, keep the logs your insurer and any forensic firm will want, and find out whether data was stolen as well as encrypted. Systems come back from immutable backups out of the attacker's reach, in the order the business needs them. NetSys has handled more than 30 ransomware incidents over the last three years with full recovery in every case, and where a disaster recovery plan already existed, the client was operating again within a day. You and your counsel decide on notifications.
Do you offer a free penetration test to Columbus companies?
Yes. NetSys offers one free service, an external penetration test: our engineers test your internet-facing systems remotely, inside a scope we both sign off on beforehand. It shows what someone outside your network could find and use, such as exposed remote-access portals, VPN appliances behind on updates, weak email security settings and services that were never meant to be public. You get a written report ordered by severity, with no obligation afterward. Internal, web application and social engineering tests are separate engagements, scoped and priced on their own.
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.
