Vulnerability Management & Penetration Testing in Texas
Knowing about a weakness is not the same as fixing it. This service pairs continuous scanning with a remediation plan somebody owns, plus periodic penetration testing that shows what an attacker could really do with what remains. Sentinel-Pros runs it for Texas businesses from Houston, remotely across the state.
The Problem
Scanners are easy to buy and produce an enormous list on day one. What defeats companies is the second half: deciding which of nine hundred findings actually matter, scheduling the changes around production, and confirming the fix held. So the report gets filed, the list grows, and a year later a customer asks for evidence of a vulnerability management program and there is nothing to show but the same untouched export. Meanwhile the things that genuinely get organizations breached tend to be dull and specific: a remote access service exposed to the internet since a contractor set it up, a server nobody dares patch because an old application depends on it, a firewall rule opened for a project that ended in 2021.
The Solution
We treat this as an operating loop rather than an annual event. Scanning runs continuously across your external footprint, internal network, and cloud tenant, and findings get filtered against how you actually work so the list stays short enough to finish. Remediation is scheduled with your team, tracked to closure, and rescanned to prove the fix took. Penetration testing then runs on a defined cadence, or ahead of a contract requirement, to test the assumptions the scanner cannot: whether a foothold becomes domain control, whether a public application leaks data, whether your monitoring notices any of it. Scanning and testing are network delivered, so location does not affect quality; Houston metro clients get on-site help with the physical remediation, and elsewhere that is scheduled from Houston. Fixed monthly retainer, scoped on a discovery call.

Engagement Process
Map The Attack Surface
First we establish what you own, which is rarely what anyone believes. Old domains, a marketing site on a forgotten host, a remote access appliance from a previous vendor, and cloud resources spun up for a trial all show up here.
Scan And Filter
Continuous scanning starts, and we cut the output down to what is genuinely reachable and genuinely damaging. A short credible list gets acted on, while a thousand line report gets ignored by everyone.
Fix In Order
Work is scheduled with whoever runs your systems, prioritizing internet-facing exposure and credential weaknesses first. Where a legacy application blocks a patch, we agree a compensating control and set a date rather than leaving it open forever.
Test The Assumptions
On the agreed cadence, testers try to chain what is left into real access. You get findings, evidence, and a plain summary suitable for a board, a prime contractor, or an insurance underwriter.
Where We Deliver This
Common Questions
A customer is demanding a penetration test report. How fast can we get one?
Scoping and scheduling take a conversation, and we would rather do a limited honest test than an instant meaningless one. If time is short we can prioritize the external and application scope your customer actually cares about, then broaden later once the contract is safe.
Is a vulnerability scan the same thing as a penetration test?
No, and vendors blur this constantly. A scan tells you what software versions and settings look weak. A penetration test has a human trying to combine those weaknesses into real access. You need the scan running continuously and the test periodically, and paying test prices for a scan is a common way to waste money.
Will scanning knock over our production systems?
Modern scanning is gentle by default, and we tune intensity for fragile equipment such as older industrial controls, medical devices, and legacy servers. Anything with real risk of disruption gets scheduled in a window you approve, and sensitive segments are handled with your team present.
We have an old application that cannot be patched. What then?
That situation is common and manageable. We isolate the system, restrict who and what can reach it, increase monitoring around it, and record the decision as a documented exception with a review date. Auditors and insurers accept managed risk; what they reject is unexamined risk.
Who does the remediation work, you or us?
Either, and it should be settled in writing during scoping. Some clients have internal staff who prefer to make the changes with our prioritization, and others want us to do the work. What does not function is a report handed over with no owner attached to each item.

BOOK A CONSULTATIONAcross Texas
The Texas systems that need this most are frequently the ones nobody wants to touch. Plants and terminals along the Gulf Coast, from the Ship Channel down to Corpus Christi, run process and safety equipment with long service lives and vendor support agreements that discourage patching, sitting on networks that now reach the business side. Water districts, electric cooperatives, and small municipal utilities across rural counties operate remote sites reachable over the internet because sending a technician two hours is impractical. Manufacturers supplying aerospace and defense primes near Fort Worth, San Antonio, and the corridor to Killeen are being asked for test evidence as a condition of renewal, not as a courtesy. Hospitals and imaging groups from the Texas Medical Center to regional facilities in Lubbock and Harlingen carry connected devices that cannot be updated on a normal cycle. Austin software companies expose customer-facing applications that a scanner cannot meaningfully evaluate and a tester can. Border logistics firms in Laredo and Pharr run portals where carriers and brokers log in from anywhere. In each case the exposure was created by someone solving a legitimate operational problem, which is precisely why an annual snapshot misses it and a running program catches it.
