About us

Offensive security firm: traditional pentesting with written scope and senior teams prioritizing clarity for leadership and engineering.

Fortress Offensive Security is built on the belief that offensive security must be explainable, defensible, and aligned with real business risk. We do not sell context-free vulnerability lists: we document hypotheses, reproducible evidence, and severity using criteria your organization can review with audit or legal.

We work as a technical partner on bounded engagements: explicit engagement rules, careful handling of sensitive data, and zero public client portfolio on the web. That lets us focus on report quality and knowledge transfer to your teams.

Principles

Working principles

Four commitments that shape every report and every interaction with your team.

Written scope

Each exercise is defined with surface, windows, and agreed limits. No implicit expansions: scope changes are documented before execution.

Rigor and traceability

Findings with evidence and reproducible steps; dual reading for leadership (risk) and engineering (remediation).

Confidentiality

Evidence and communications limited to agreed channels; respect for internal policies and legal requirements from kickoff.

Senior teams, not a factory

Small teams with senior experience on the campaign. No generic templates or timeline promises that depend on scope not yet closed.

Experience

Sectors where we have performed pentesting

Overview of contexts and surfaces common in our campaigns. We do not publish a client portfolio: this describes environment types, not specific contracts.

Primary specialty
PCI DSSCNBVRegulated environment

Financial, banking, and fintech

Applications, APIs, and digital channels under regulatory pressure: deep testing focused on controls, segregation, and evidence defensible in audit.

Public sector and government

Evaluations bounded to explicit scope, coordination with internal teams, and respect for information classification in agencies and bodies.

Retail

POS, e-commerce, promotions, and associated logistics chains: business-rule abuse, fraud, and cardholder data exposure.

Logistics, transport, and telemetry

Tracking platforms, fleets, and third-party APIs: identity abuse, telemetry, and location or cargo data leaks.

FMCG and food

ERP, plant, and distribution partners: campaigns focused on order integrity, promotion fraud, and cold-chain documentation.

Education and research

Campus, federated identity, and labs: hardening reviewed with offensive testing on exposed services and research data.

Training

Team certifications

Training and technical validation in offensive pentesting: web, mobile, cloud, and industry-recognized practical certifications.
