New Braunfels and Seguin Businesses Stop Ransomware

New Braunfels and Seguin sit along the I-35 corridor between San Antonio and Austin, two of the fastest-growing metros in the country. The businesses that serve these communities, including CPA firms, dental practices, medical offices, HVAC contractors, and construction companies, are growing with them. But most of these companies are running IT infrastructure that was set up years ago by whoever was cheapest, and their security posture reflects it. Infonaligy has spent the past two years helping businesses across this region recover from ransomware incidents, rebuild their IT foundations, and implement the kind of security program that keeps them protected as they scale.

The IT Gap in Growing Central Texas Markets

A 60-person HVAC company in New Braunfels and a 30-person dental practice in Seguin face the same fundamental challenge: they’ve outgrown their current IT setup but aren’t large enough to hire a full IT department. The typical pattern looks like this: a local contractor installed a server and some workstations five years ago, set up basic antivirus, and checks in when something breaks. There’s no monitoring, no patching schedule, no documentation, and no security program.

This gap is especially dangerous for businesses that handle regulated or sensitive data. CPA firms manage client financial records, tax returns, and Social Security numbers. Dental and medical practices store protected health information under HIPAA. Construction companies handle bid documents, contracts, and employee records. All of this data has value to attackers, and all of these industries have experienced significant ransomware activity according to the FBI’s IC3 2024 report.

The labor market makes self-solving this problem nearly impossible. Qualified IT professionals in central Texas can command salaries that a 40-person company simply cannot justify, and even if they could, a single hire can’t cover security, infrastructure, help desk, and strategic planning. That’s why managed IT services exist for this market segment.

What Ransomware Looks Like in a Small Market

The ransomware attacks we’ve responded to in New Braunfels and Seguin followed predictable patterns. Attackers aren’t writing custom exploits for a dental practice in Seguin. They’re sending thousands of phishing emails and exploiting unpatched vulnerabilities in internet-facing systems, then deploying commodity ransomware once they’re inside.

In one engagement, a construction company’s project management server was encrypted after an attacker exploited a known vulnerability in their VPN appliance. The vulnerability had a patch available for months, but nobody was monitoring or managing the device. The company lost access to active project files, bid documents, and accounting data for nearly a week.

In another, a CPA firm’s file server was hit during tax season, encrypting client returns and supporting documentation. The firm’s backups existed but hadn’t been tested, and the backup drive was network-attached and accessible from the compromised workstation, which meant it was encrypted too.

These aren’t sophisticated nation-state attacks. They’re preventable incidents that happen because basic IT operations aren’t in place. Patching, backup validation, network segmentation, and endpoint detection would have stopped both of them.

How We Built Enterprise Security for Local Businesses

Every engagement in this region starts with a comprehensive assessment. We map the network, inventory every device, identify vulnerabilities, and document the current state of backups, patching, and access controls. This assessment gives business owners a clear picture of their risk and a prioritized remediation plan.

From there, we deploy a full managed security and IT stack:

RMM and Patch Management: Remote Monitoring and Management agents go on every endpoint. This gives us real-time visibility into device health, software versions, and patch status. We push patches on a regular schedule and validate that they install successfully. This single step eliminates the most common attack vector for ransomware in small businesses.

EDR on Every Endpoint: Traditional antivirus is not enough. We deploy behavioral-based endpoint detection and response that catches living-off-the-land attacks, fileless malware, and zero-day threats. When an HVAC technician’s laptop gets compromised at a job site, EDR contains the threat before it spreads to the office network.

Managed Firewalls with Segmentation: We replace unmanaged consumer-grade routers with enterprise firewalls that we configure and monitor. For medical and dental practices, we segment clinical systems from administrative networks and guest Wi-Fi. For construction companies, we isolate project management systems from general office traffic.

SIEM and 24/7 SOC: Every log source feeds into our Security Information and Event Management platform, monitored by our Security Operations Center around the clock. Alerts are investigated by human analysts, not just automated rules. When something suspicious happens on a Saturday night at a CPA firm in New Braunfels, our team is already looking at it.

Backup and Recovery: We implement and manage backup systems that follow the 3-2-1 rule: three copies of data, on two different media types, with one copy offsite. More importantly, we test recovery regularly. A backup you’ve never tested is a backup you can’t trust.

Strategic IT Leadership Through vCIO

The technology stack is only half the equation. Business owners, especially CEOs and CFOs, need someone who can translate IT decisions into business outcomes. Our virtual CIO service provides that bridge.

For a CPA firm, vCIO means planning technology upgrades around tax season, ensuring the firm meets IRS data security requirements under Publication 4557, and presenting a clear IT budget that the partners can plan around. For a construction company, it means making sure field crews have reliable access to project files, that the company’s cyber insurance application is accurate, and that IT spending scales with the business rather than lurching from crisis to crisis.

Quarterly business reviews give ownership teams a regular checkpoint on IT health, security posture, and upcoming projects. This is the operating discipline that separates a managed IT partnership from a break-fix vendor relationship.

What These Businesses Look Like Now

The CPA firms, dental practices, HVAC companies, medical offices, and construction businesses we serve in New Braunfels and Seguin now run enterprise-grade IT and security. They have 24/7 monitoring, tested backups, patched systems, and a strategic IT plan. Their cyber insurance renewals are straightforward because they can answer every question on the application honestly. Their staff can focus on serving customers instead of troubleshooting technology.

Businesses along the I-35 corridor between San Antonio and Austin are growing fast. The ones that invest in real IT operations and managed security now are the ones that will scale without a catastrophic security incident derailing their progress.
