Houston Manufacturing Cybersecurity Scores Worst of Any Industry

The three industries, side by side.

Manufacturing is the lowest-scoring industry in the Houston Area Security Index, with a 1.57 GPA across 953 businesses and a 46.6% fail rate, behind both legal and CPA practices.

The gap between industries is smaller than the gap between cities, which matters. Manufacturing is not in a different league of bad. It is a few hundredths of a GPA point behind law and accounting, with a higher fail rate. That is a tight race, and it means a handful of targeted fixes is enough to pull a Houston manufacturer level with the professional-services firms that lead the index.

CPA firms have the lowest fail rate of the three at 42.7%, which lines up with what compliance pressure does to security. IRS oversight and AICPA peer review create real consequences for sloppy IT, so accountants invest. Manufacturers do not face that same outside force, so the setup work slips. The number is not a verdict on the people. It is a measure of what nobody was required to do.

Three structural reasons, all fixable.

Manufacturers trail because they run older systems, mix operational technology with regular IT, and historically spend less on IT per employee than professional-services firms.

A law firm is laptops, email, and a document system. A manufacturer is all of that plus the plant: programmable controllers, machine monitoring, a remote-access link the equipment vendor set up during installation, and a server in a closet that has run the same job for a decade. Each of those is a place a security setting can be missing, and the external scan finds every one of them. In 30 years doing this, the recurring discovery on a Houston shop floor is a remote-access system for a machine that nobody has logged into since the install, still wide open to the internet.

• Older infrastructure. Equipment that runs for fifteen years often sits on operating systems and firmware that stopped getting security updates years ago.
• OT and IT mixed together. When the machine network and the office network share a path, a gap on one side exposes the other, and the scan sees the weakest link.
• Lower IT spend per employee. Margins are tight and dollars go to production, so the configuration and monitoring work that professional-services firms fund tends to wait.
• Forgotten remote access. Vendor-installed remote links for plant equipment are the classic exposed door, left open long after anyone needed them.

The bottom of the index is almost all manufacturing.

Sugar Land manufacturers are the single worst-performing group in the Houston Area Security Index, with a 1.15 GPA and 65% failing. Manufacturing fills three of the five weakest region-and-industry combinations in the entire dataset.

When you cut the data into city-and-industry cells, the floor is dominated by plants. Sugar Land manufacturing sits dead last. The Woodlands and Katy manufacturing are not far above it. If you run a manufacturing operation in Sugar Land, the odds say you have publicly visible problems an attacker is already looking at, and that is worth a sober afternoon to confirm.

Three of the five worst cells are manufacturers, and three of the five are in Sugar Land. The overlap, a Sugar Land plant, is the toughest spot in the metro to be sitting in without a security plan.

Four work streams, none of which stop the line.

A Houston manufacturer moves from a failing grade to a passing one through four fixes: DNS records, website security settings, network exposure cleanup, and tested backups. Most plants make the jump in 30 to 60 days.

None of this requires replacing the machines or pausing production. It is the configuration and cleanup work that should have happened during the last IT refresh and did not. The order matters, because the cheapest fixes also move the grade the most.

• Publish DNS records. SPF, DKIM, and DMARC stop attackers from spoofing your domain to bill your customers or trick your purchasing team. A few hours of work, no hardware.
• Fix the website settings. Security headers and a clean TLS configuration on the company site move the application security score, usually within one billing cycle.
• Close the network exposure. Shut public remote-desktop ports, patch firewall firmware on a schedule, and retire VPN appliances older than five years. This is where the plant-floor surprises live.
• Back it up properly. Immutable, off-site, tested backups so a ransomware hit on a production system is a recovery, not a shutdown that costs you a shipping week.

CinchOps is a managed IT services provider based in Katy, Texas, serving small and mid-sized businesses across the Houston metro area. CinchOps specializes in cybersecurity, network security, managed IT support, VoIP, and SD-WAN for businesses with 10 to 200 employees.

• For manufacturing, we map the full attack surface, office and plant, and separate the machine network from the office network so one gap does not expose both.
• Through cybersecurity services, we publish SPF, DKIM, and DMARC, fix website security headers and TLS, and close the exposed remote access that drags the network score down.
• With managed IT support, we patch firmware on a schedule and watch the environment around the clock, so old equipment stops being an open invitation.
• With business continuity and disaster recovery, we keep immutable, tested backups so a hit on a production system means hours of downtime, not a lost shipping week. We serve plants across Houston, Sugar Land, and Katy, with related work in oil and gas.

Manufacturing landing last in the index is not a fixed sentence, it is a starting point. The plants that come out ahead are not the ones with the biggest IT budgets, they are the ones that closed the forgotten doors before someone tried the handle. CinchOps does that work for Houston-area manufacturers every day, around production rather than through it.
