Cybersecurity Services in Indianapolis, IN
Indianapolis has seen what a breach costs up close, from the 2015 Anthem attack to ransomware at Eskenazi Health and the city's housing agency. NetSys protects Indianapolis organizations with managed detection and response, identity controls, email security and tested backups, all run remotely from Brooklyn by engineers and analysts who watch the alerts.
The short answer
NetSys provides cybersecurity services to Indianapolis businesses: ThreatDown managed detection and response on every endpoint, Microsoft Defender for Business, multifactor sign-in with Entra ID Conditional Access, Barracuda email protection, KnowBe4 training, Keeper password management, Rapid7 vulnerability scanning and immutable backups.

How cybersecurity is delivered to Indianapolis organizations
Security is the part of IT best suited to remote delivery, and NetSys runs all of it from Brooklyn without engineers in Indiana. ThreatDown agents report behavior from every laptop and server to analysts who can isolate a device, stop a process or roll back ransomware file changes within minutes, at 3 a.m. as readily as at noon. Sign-in risk, device compliance and Conditional Access are enforced in your Entra ID tenant. Barracuda inspects mail before it reaches inboxes, and Rapid7 InsightVM scans for missing patches and exposed services on a schedule. When an incident needs hands on a machine, it is shut down remotely or a staff member unplugs it while an engineer directs, and the replacement ships already enrolled. 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 recent Indianapolis attacks show about entry points
Three local incidents cover the common ways in. At Eskenazi Health, the hospital later found, attackers had been inside its network from about May 19, 2021 until the attack was discovered in early August; ambulances were diverted, and stolen files on about 1.5 million people appeared on a leak site. In October 2022, ransomware at the Indianapolis Housing Agency held up rent payments to Section 8 landlords and exposed data on more than 212,000 people. And in January 2018, Hancock Health in Greenfield paid about $55,000 in bitcoin after attackers entered through an administrative account set up for a vendor. Long dwell time, a weak point in a public agency and an outside vendor's credentials are what our controls are built to catch: behavioral detection, multifactor sign-in everywhere, and vendor access that is time-limited and logged.
The controls in a NetSys security program
Every managed security agreement starts with the same layers, then adds what your risks call for. Endpoints run ThreatDown EDR with managed detection and response, alongside Microsoft Defender for Business where your licensing includes it. Identities get multifactor sign-in, Conditional Access policies that block unmanaged devices and risky locations, and Keeper for shared credentials. Email passes through Barracuda, and SPF, DKIM and DMARC records reduce spoofing of your domain. Staff take KnowBe4 training with simulated phishing, and the results go into your quarterly report. Backups from Datto SIRIS or Veeam are immutable, stored off premises and restored on a test schedule. Rapid7 scans turn into a ranked patch list, and Cisco Meraki or Fortinet firewalls separate guest, office and equipment networks.
Sector risks: life sciences, health care, insurance and logistics
Indianapolis concentrates industries that attackers value. Eli Lilly and Corteva Agriscience have their headquarters here and Roche Diagnostics its North American base, so contract labs, suppliers and consultants around them handle research data and drawings worth stealing; those firms need data-loss controls and tight sharing settings in SharePoint. Medical practices answer to the HIPAA Security Rule. Insurers and agencies, from Elevance Health and OneAmerica downtown to CNO Financial in Carmel, fall under Indiana's insurance data security law and its three-business-day reporting window. Distributors in Plainfield and Whitestown face invoice and freight-payment fraud through compromised email, so we pair mailbox-rule monitoring with a call-back rule for payment changes. Counties, cities and school corporations must report incidents to the Indiana Office of Technology within 48 hours, and their vendors should expect that clock in contracts.
Cybersecurity consulting and the first 30 days
A security engagement opens with evidence rather than a sales pitch. In the first two weeks we run the free external penetration test against the internet-facing scope you agree to, scan internal systems with Rapid7, review Microsoft 365 sign-in settings and mailbox rules, and check how backups are protected and when anyone last restored one. The findings arrive as a written, ranked list with costs. If you go ahead, the next two weeks deploy ThreatDown, tighten Conditional Access, enroll everyone in multifactor sign-in, turn on Barracuda and start training. For companies with an internal IT team, the same work can run as cybersecurity consulting plus co-managed security, with our analysts watching alerts while your staff keep running the systems they know.
Cybersecurity in Indianapolis: 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
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 Indianapolis
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 Indianapolis: FAQs
How does cybersecurity work for Indianapolis organizations?
Remotely and continuously. ThreatDown monitors every enrolled device 24/7, and analysts isolate a machine within minutes when behavior looks like ransomware or credential theft. Identity, email and device policies are managed in your Microsoft 365 tenant from Brooklyn, and no NetSys engineer works on site in Indianapolis. The help desk is staffed from 4 a.m. to 11 p.m. Eastern seven days a week, and severe incidents such as ransomware or an email outage go directly to your dedicated engineer at any hour, day or night.
How much do cybersecurity services cost in Indianapolis?
Security is part of every NetSys managed IT agreement, which carries a per-user monthly price set after an assessment. Organizations that keep their own IT and want security only can buy managed detection and response, email protection, training and backup on the same per-user basis. The figure depends on how many endpoints and servers you run, how many sites, and whether you need compliance documentation such as a HIPAA risk analysis or a NIST SP 800-171 self-assessment. Penetration tests beyond the free external test, and remediation projects, are quoted after scoping. We publish no price list.
Which cybersecurity requirements apply to businesses in Indianapolis?
Most firms start with Indiana Code 24-4.9, which requires telling affected Indiana residents about a breach no later than 45 days after it is discovered and notifying the Attorney General. Since January 1, 2026, the Indiana Consumer Data Protection Act has covered businesses that process personal data on at least 100,000 Indiana residents a year; the Attorney General must allow 30 days to fix a violation before suing. Industry rules add more: Indiana Code 27-2-27 for insurance licensees, the HIPAA Security Rule for medical practices, the FTC Safeguards Rule for tax preparers, SEC Regulation S-P for advisers and NIST SP 800-171 for defense suppliers. This is general information, not legal advice.
What is included in managed security services?
Managed security means people watching the tools, not just licenses. NetSys deploys and tunes the stack, then works it: analysts triage ThreatDown alerts around the clock, Entra ID sign-in risks are reviewed, Barracuda quarantines are checked and Rapid7 findings feed a monthly patch plan. Each quarter you get a report on incidents, phishing-test results, vulnerabilities closed and still open, and backup restore tests. When an alert turns out to be real, we contain it, find how the attacker got in, restore what was affected and document the timeline your insurer or counsel will want.
What happens if an Indianapolis business is hit by ransomware?
Call the help desk or your dedicated engineer; ransomware skips the queue. We isolate affected machines through ThreatDown, disable compromised accounts, preserve logs for your insurer and investigators and work out how the attacker entered. Recovery comes from immutable backups, starting with identity and the systems the business needs first. Of the more than 30 ransomware cases NetSys has handled in the past three years, all were fully recovered, and clients with a disaster recovery plan were running again within 24 hours. Afterward we close the entry point and support your counsel through Indiana's 45-day notice timeline.

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.
