Black, Grey & White Box

Penetration Testing

Black, grey, and white box penetration testing — including hardware and firmware reverse engineering — to help you meet requirements like PCI DSS 11.3.

Overview

Penetration Testing, On Demand

Our penetration testing draws on extensive experience across black, grey, and white box methodologies, with particular depth in reverse engineering hardware layouts and firmware code alongside traditional software testing.

Every engagement is scoped with clear rules of engagement before any active testing begins, and results are delivered in a report built to satisfy requirements like PCI DSS 11.3 — not just a raw scanner export.

We test the way a real attacker would, then walk your team through exactly what we found and how to close it.

What’s Included

  • Scoping & rules of engagement, agreed in writing
  • Black, grey, or white box testing depending on your goals
  • Hardware & firmware testing where relevant, alongside software
  • Exploitation and proof-of-concept, not just automated scan output
  • A report structured to support PCI DSS 11.3 and similar compliance needs
Why eStreetSecurity

On Demand. Accountable. Battle-Tested.

One App for Services, Training & Placement

The specialists who work your engagement come from the same pipeline we train and place into full-time roles — not a black-box list of freelancers.

Written Scope Before Work Begins

You get a defined scope and proposal before any commitment — no open-ended retainer with vague deliverables.

Backed by a 24/7 Operations Center

Engagements are supported by our AI & Cybersecurity Operation Center for monitoring, escalation, and incident coverage.

Not a Big Firm. Not a Freelance Board.

You get senior, hands-on specialists directly — not a junior team learning on your account, and not a one-off contractor with no accountability behind them.

Scoping & ROE

We define targets, methodology, and rules of engagement in writing before any testing starts.

02

Active Testing

Our team attempts to identify and exploit real weaknesses across the agreed scope.

03

Exploitation & Validation

Findings are validated with proof-of-concept, not just flagged by a scanner.

04

Reporting & Debrief

You get a prioritized report plus a walkthrough of findings and remediation guidance.

Questions

Common Questions

What's the difference between black, grey, and white box testing?

Black box testing starts with no internal knowledge, simulating an outside attacker. Grey box uses partial knowledge, like a user-level credential. White box uses full access, simulating an insider or a fully informed attacker.

Do you test hardware and firmware, not just software?

Yes — our team has particular depth in reverse engineering hardware layouts and firmware code, alongside traditional application and network testing.

Will this help with PCI DSS compliance?

Our reporting is structured to support requirements like PCI DSS 11.3. Tell us your specific compliance driver during scoping and we'll tailor the report accordingly.

How long does an engagement take?

It depends on scope. A focused web application test may take days; a full environment test with hardware components takes longer. You'll get a timeline in the written proposal.

Why choose eStreetSecurity for this?

You get senior, hands-on testers directly — not a junior team learning on your account — backed by a written scope and a 24/7 Operations Center for anything urgent that surfaces mid-test.
