Penetration Testing in Louisiana

St. John Cybersecurity is an independent penetration testing practice based in Lafayette, Louisiana, serving businesses across Acadiana, Baton Rouge, New Orleans, and the rest of the state. When you hire me, the person you talk to is the person doing the testing — no sales layer, no outsourced offshore team.

A Louisiana Tester, Not a Fly-In Firm

Most penetration testing firms serve Louisiana from somewhere else: a remote-only engagement, or a consultant flown in with travel billed back to you. Being based in Lafayette means I can be on-site anywhere in southern Louisiana the same week, and anywhere in the state without the travel premiums national firms charge. For the work that genuinely benefits from someone in the building — internal network testing, wireless assessments, walking down an OT environment — that matters.

Businesses I Work With

My background is IT and OT security engineering, which fits the industries that drive Louisiana's economy:

  • Energy and oilfield services — operators, service companies, and suppliers with a mix of corporate IT and field control systems.
  • Industrial and manufacturing — plants and processing facilities where testing has to respect production uptime and safety systems.
  • Maritime and logistics — ports, terminals, and the businesses that support them.
  • Healthcare practices — clinics and specialty practices with HIPAA obligations and patient data to protect.
  • Community banks and credit unions — institutions whose examiners and insurers expect regular independent testing.
  • Professional services and MSPs — firms that hold sensitive client data, and IT providers who want independent validation of the environments they manage.

Why Louisiana Businesses Schedule a Pentest

The most common triggers I see: a cyber insurance application or renewal that now asks for evidence of security testing, a large customer sending a vendor security questionnaire, and compliance frameworks — HIPAA for healthcare, PCI DSS for anyone handling card payments, and CMMC for companies in the defense supply chain. Louisiana's Database Security Breach Notification Law also requires businesses holding Louisiana residents' personal information to maintain reasonable security procedures and to notify affected residents if that data is breached — and it's far cheaper to find the hole yourself than to fund a notification campaign.

And beyond paperwork: small businesses are now the primary target for ransomware crews precisely because they're less likely to have been tested. A pentest tells you, concretely, what an attacker would find and do — before one does.

On-Site or Remote

External penetration testing, web application testing, and security consulting are delivered fully remote — your location in the state doesn't matter. Internal network testing can be done on-site or through a shipped testing device on your network. Wireless assessments and OT/ICS work are performed on-site, and I schedule those anywhere in Louisiana. Businesses outside Louisiana: remote engagements are available nationwide.

How an engagement works

01

Scope

We define what's in bounds, your goals, and any operational constraints. For OT and production systems, safety and uptime come first.

02

Test

Hands-on testing the way a real attacker works. Findings are exploited and verified manually, proof of impact, not just a scanner flag.

03

Report

A prioritized report with clear remediation steps and proof of impact, written to be acted on, not a 200-page scanner dump.

04

Retest

Once your team has remediated, I re-verify the fixes so you can prove the issues are actually closed.

Frequently asked

Do you travel outside Lafayette?
Yes — on-site work is available statewide: Baton Rouge, New Orleans, Lake Charles, Alexandria, Shreveport, and everywhere in between. Acadiana-area engagements usually carry no travel cost at all.
How much does a penetration test cost in Louisiana?
It depends on scope — the number of systems, applications, and locations in play. Small-business engagements are priced well below what national firms charge for the same work. See how much a pentest costs for realistic ranges, or reach out for a quote.
Can testing be done fully remote?
External, web application, and consulting engagements are fully remote. Internal testing works remotely too, via a small testing device shipped to your office. Only wireless and OT assessments require me on-site.
Who actually performs the testing?
I do — every engagement, personally. You're never handed off to a junior tester or an outsourced team, and the person writing your report is the one who found and verified the issues in it.
