Free Attack Surface Check for Your Houston Business

External Network Scanner

Find out what attackers see when they look at your public IP range. We scan for exposed ports, known vulnerabilities, SSL certificate issues, and open services that attackers actively exploit. Authorized, non-intrusive, and free for Houston businesses.

What We Offer

Comprehensive solutions tailored for Houston-area businesses

Public IP Range Discovery

We start by mapping your full external footprint — every public IP address tied to your business, including cloud workloads in AWS, Azure, and GCP, plus any forgotten legacy ranges. Most Houston businesses are surprised to find 2x to 3x more internet-facing assets than they expected.

Open Port and Service Enumeration

For every IP in scope, we identify which TCP and UDP ports are open and which services are listening. We flag dangerous exposures like RDP, SMB, Telnet, FTP, database ports, and management interfaces that should never be reachable from the internet.

Known Vulnerability Detection

We cross-reference detected services and version banners against the CISA Known Exploited Vulnerabilities catalog and the National Vulnerability Database. Critical findings include unpatched VPNs, exposed Exchange servers, and known-vulnerable web applications actively being exploited.

SSL and TLS Certificate Audit

Every HTTPS endpoint is checked for expired or expiring certificates, weak ciphers, deprecated TLS versions (1.0 and 1.1), self-signed certificates, hostname mismatches, and known CA issues. Certificate problems are the easiest external finding to fix and the hardest to hide from auditors.

Web Application Surface Mapping

We catalog public web applications, admin portals, login pages, and API endpoints. Forgotten staging environments, exposed phpMyAdmin, default Apache pages, and unprotected developer interfaces are surfaced with severity ratings.

Houston Threat Context

Findings are prioritized against actual attacker activity targeting Houston businesses. We track which CVEs are being weaponized against Texas energy, healthcare, and SMB sectors so your remediation list reflects current threats — not a generic global vulnerability dump.

Why Choose LayerLogix?

Serving businesses throughout the Greater Houston area including Houston, The Woodlands, Spring, Katy, Sugar Land, Conroe, Pearland, Dallas, Austin.

100% Free, No Credit Card Required

The external attack surface scan is completely free for Houston businesses. We deliver a detailed PDF report within 5 business days — no payment, no contract, no recurring obligation.

Educational Without Risk

Unlike paid penetration tests, our scan only performs non-intrusive reconnaissance against your public-facing assets. Nothing is exploited, nothing is changed, and there is zero risk of disrupting production systems.

Authorized and Documented

Every scan is conducted with written authorization from the asset owner. You receive a signed Rules of Engagement document before any scanning begins, satisfying internal compliance and ISP terms of service.

Foundation for a Real Security Program

A free scan is the starting point. If you want continuous attack surface monitoring, full penetration testing, or vulnerability remediation, LayerLogix offers managed security services as separate engagements — but only if you want them.

Demonstrates Risk to Leadership

Nothing convinces a CEO or board to fund cybersecurity faster than a written report showing exposed RDP, expired SSL certificates, and known-vulnerable VPN appliances on the company perimeter. The scan output is built for executive consumption.

Frequently Asked Questions

Is this really free? What is the catch?▼

Yes, the external attack surface scan is completely free with no credit card or payment information required. We invest the analyst time hoping that businesses with significant exposure will engage LayerLogix for remediation, managed security, or penetration testing. There is no obligation — many recipients use the report to fix issues internally and that is perfectly fine.

What data do you collect and how is it secured?▼

We collect your business name, contact information, and authorized IP ranges. The scan results contain technical findings about your perimeter (open ports, services, vulnerabilities) but no internal data, customer information, or credentials. All findings are stored encrypted, accessed only by the analyst on your engagement, and deleted 60 days after delivery unless you become a client.

Will the scan disrupt my business operations?▼

No. The scan uses non-intrusive reconnaissance techniques — passive DNS lookups, banner grabbing, and rate-limited port enumeration. We do not exploit vulnerabilities, do not perform denial of service testing, and do not run authenticated checks against your systems. The bandwidth impact is negligible and falls within normal internet background traffic levels.

Can a free scan replace a real penetration test?▼

No. A penetration test is an in-depth, authenticated engagement where security professionals actively exploit findings, attempt lateral movement, and validate impact — typically a 1 to 4 week engagement with a written attestation report suitable for compliance audits. The free scan is excellent for surfacing low-hanging fruit and building a remediation roadmap, but it is not a substitute for full penetration testing required by SOC 2, PCI-DSS, HIPAA, or CMMC.

Is external scanning legal? Will it cause issues with my ISP?▼

Scanning is legal when conducted with written authorization from the asset owner. We require a signed Rules of Engagement document before any scanning begins. We notify your ISP if requested, throttle scan rates to avoid triggering DDoS mitigation, and operate from documented IP ranges so security tools can verify the activity is authorized.

What if I am hosted in AWS, Azure, or GCP — can you still scan?▼

Yes. AWS, Azure, and GCP all permit customer-authorized vulnerability scanning of customer-owned resources without prior cloud provider notification (this changed in 2019 for AWS). We can scan your cloud workloads exactly the same way as on-premise infrastructure, with the same Rules of Engagement document.

How is this different from Shodan or Censys?▼

Shodan and Censys are passive databases of internet-wide scan data — they show what their crawlers happen to have collected, which may be days or weeks old. Our scan is targeted, fresh, and includes vulnerability correlation, severity prioritization, remediation guidance, and a written report. We use Shodan and Censys data as input but go far beyond their raw output.
