Traditional offensive pentesting
Penetration testing run by senior operators, with frozen scope and decision-ready reporting.
Fortress Offensive Security is an offensive security firm: disciplined planning, controlled exploitation where appropriate, reproducible evidence, and dual reading for leadership and engineering teams — without generic catalog noise.
Only with explicit authorization · NDA and written scope before invasive testing

Engagement frame
Commercial transparency without promising timelines that depend on scope not yet closed.
Operational trust
We work with teams that already take risk seriously — without invented logo marketing.
Discretion by default
No public client portfolio on the web. Cases and logos only with explicit authorization.
Scope always in writing
Assets, windows, exclusions, and engagement rules agreed before invasive activity.
Credentials under control
Operator certifications and CVs are shared in advanced commercial phases or under NDA, per procurement process.
Service lines
Six areas of work with offensive testing at the core
Senior-led manual pentesting is our flagship line. AppSec, cloud, defense, vulnerability management, and operational support complement it under the same frozen-scope frame.
Flagship line
Offensive testing
Manual pentesting by surface with black, gray, or white box modalities per SOW.
Attack surface management (ASM)
Inventory and prioritization of Internet-exposed assets before or alongside the pentest.
AppSec and modern stack
Web, REST/GraphQL APIs, and iOS/Android mobile with a focus on business logic.
Common lineEnterprise infrastructure
Internal/external network, AD, and lateral movement under signed rules.
Cloud
IAM, configuration, and exposure across AWS, Azure, and GCP.
Emerging technology
In-app AI, biometrics, and MFA where legal frameworks allow.
Specialized
Reverse engineering, controlled phishing, and high-criticality scenarios.
When you need to reinforce the lifecycle, design, or operations:
Beyond the pentest
Advisory and services that complement offensive evaluation — from threat modeling to remediation and ongoing validation.
AppSec across the SDLC
Secure design, code, and integration before and during development — complements manual pentest.
View lineDefense & awareness
Exercises that test response, roles, and communication without production impact. Measurable training with controlled campaigns and metrics by team or role.
View lineCloud security
Cloud posture and privileges — complements offensive cloud pentest.
View lineVulnerability management
Discovery, prioritization, and ongoing tracking aligned to risk and compliance.
View lineOperational support
Recurring sessions to close findings with your engineering or infra team — pair remediation, prioritization, and knowledge transfer.
View lineLifecycle
A shared frame for every engagement
Three stages connect commercial, delivery, and closure. Pentest, advisory, cloud, and vuln management share the same cycle with frozen scope.
Pre-contract
Discovery call, objective alignment, and written scope. Every line — pentest, advisory, cloud, vuln management — starts here with a frozen scope and signed frame before any technical work.
Stage 1
Execution
Kickoff, delivery per SOW, and formal readout. Workshops, testing, posture reviews, and operational support all run under the same traceability and escalation rules.
Stage 2
Post-delivery
Remediation on your side, validation where contracted, and documented closure. Operational support and follow-up cycles close the loop when applicable.
Stage 3
Training and certifications
Team technical validation
Practical certifications in web, mobile, cloud, and network pentesting — the same hands that run the campaign.
