Vulnerability Management & Penetration Testing in Houston

You cannot defend what you have never inventoried. Sentinel-Pros finds what is exposed across your network, endpoints, and cloud, ranks it by what an attacker could realistically do with it, and then works the list down with you. Periodic penetration testing checks whether the defenses hold when someone actively tries.

The Problem

Scanning is easy to start and hard to finish. A tool gets pointed at the network, produces four thousand findings, and the report sits in a shared drive because nobody can tell which twelve items matter. Meanwhile the genuinely dangerous exposures are usually not on the list at all: a remote access appliance nobody has patched since installation, a forgotten server under a desk still joined to the domain, a cloud storage bucket a developer opened for a one time transfer three years ago. Then a customer or an underwriter asks for a current penetration test report and you have either nothing or a document from a vendor who ran the same automated scan and put a logo on it.

The Solution

Sentinel-Pros runs scanning continuously rather than annually, across internal networks, internet facing systems, endpoints, and cloud tenants, and then does the part most providers skip: triage. Findings are ranked by exploitability and business impact in your environment, not by a generic severity score, and each one comes with a specific remediation owner and a target date. We do the fixing where it falls inside your managed environment and track the rest with your other vendors. Penetration testing is conducted on a defined cadence by testers who attempt real attack paths, and you get both a technical appendix and an executive summary. Scanning and testing are performed remotely, and on-site work in the Houston metro covers internal assessments, physical network checks, and equipment that has to be reached in the building.

WHAT'S INCLUDED

Core Responsibilities

Finding What Is Exposed

External attack surface discovery covering the internet facing systems, remote access portals, and forgotten subdomains that face the public.
Authenticated internal scanning of servers, workstations, network gear, and virtualization hosts, including devices missing from the official inventory.
Cloud and Microsoft 365 configuration review, where the risk is usually a permission or a sharing setting rather than a missing patch.

Turning Findings Into Work

Risk ranking based on whether a finding is actually reachable and what it would give an attacker in your specific environment.
A remediation plan with named owners, target dates, and an honest note where the fix requires a vendor, a budget, or an outage window.
Exception tracking for the systems that cannot be patched yet, with the compensating controls that reduce the risk in the meantime.

Penetration Testing

External and internal testing that chains findings into realistic attack paths instead of listing them in isolation.
Credential and phishing based testing that reflects how intrusions actually begin, agreed with you in scope beforehand.
A retest after remediation, so the final report shows what was fixed rather than only what was wrong.
HOW IT WORKS

Engagement Process

01

Discovery and scope

We establish what you own, including the assets nobody documented, and agree what is in scope for scanning and for testing. Pricing is scoped on that discovery call as a fixed monthly retainer.

02

Baseline scan and triage

The first full pass usually produces a large volume of findings. We reduce it to a working list ordered by real risk, and separate what we will fix under management from what belongs to another party.

03

Remediate on cadence

Patching and configuration work proceeds on an agreed rhythm with change windows that respect your operations. Progress is measured by findings closed and time to close, not by scans run.

04

Test and retest

Penetration testing happens on schedule or ahead of a customer requirement. Results feed straight back into the remediation queue, and a retest documents the corrected state for whoever asked.

FAQ

Common Questions

What is the difference between a vulnerability scan and a penetration test?

A scan lists conditions that could be exploited. A test has a person attempt to exploit them and see how far they get. Many vendors sell the first and call it the second, so ask what a report actually describes before you accept it as a penetration test.

A customer is requiring an annual penetration test before contract renewal. Can you meet that?

Yes, and we will read the contract language first, because requirements differ on scope, tester independence, and whether a retest is expected. Scheduling matters too, so the report is current at the moment they ask rather than eleven months old.

Will scanning disrupt production systems?

It is planned so that it does not. Sensitive systems such as clinical devices, plant control networks, and legacy line of business servers are handled with reduced intensity, passive methods, or scheduled windows agreed in advance.

We have equipment that cannot be patched. What then?

That situation is common with imaging equipment, instrumentation, and older industrial systems. The answer is isolation and compensating controls: segment it, restrict who can reach it, monitor it closely, and document the decision so an auditor sees a considered exception rather than an oversight.

How often should testing happen for a company our size?

Annually is the usual baseline, with additional testing after major changes such as a new remote access setup, a cloud migration, or an acquisition. Continuous scanning fills the gap between tests so you are not blind for eleven months.

Vulnerability Management & Penetration Testing for Houston, Texas

Exposure in Houston tends to be inherited. Energy services companies in the Energy Corridor grew through acquisition, and each acquired firm arrived with its own domain, its own remote access, and its own unpatched appliance that nobody has logged into since the deal closed. Companies along the Ship Channel and in Pasadena and Deer Park run a mix of business systems and operational technology, where instrumentation and control equipment cannot simply be patched on a Tuesday and needs isolation instead. Clinics and specialty practices near the Texas Medical Center operate imaging and diagnostic devices running software the manufacturer froze years ago, and HIPAA obligations still apply to the data on them. Aerospace and defense suppliers in Clear Lake near NASA Johnson Space Center are asked to demonstrate vulnerability management as a named practice under CMMC, with evidence of both scanning and remediation. Logistics and customs firms tied to the Port of Houston expose booking and documentation portals to the public internet because their customers need them, which puts the attack surface outside the firewall by design. Professional services firms Downtown and in the Galleria increasingly get contract clauses requiring a current penetration test. Add the local pattern of temporary field connectivity and equipment moved after flooding, and the inventory drifts constantly. Scanning once a year in a city like this describes a network that no longer exists.
