Offensive Security

Penetration testing, exploit development, and zero-day research across application, network, cloud, and embedded targets.

Engage on this 24/7 hotline
Overview

Targeted testing led by operators with offensive backgrounds.

Versus offensive security is the deeper, narrower complement to our cyber warfare practice. Where a red team tests the response, offensive security tests the target — finding the bugs, building the exploits, and producing remediation guidance your engineers can act on the same week.

Our offensive operators include former exploit developers, kernel and firmware researchers, and senior pen testers with field time across application, network, cloud, and embedded targets. We go deep on application logic, cryptographic flaws, kernel and driver targets, and the cloud control planes most teams do not have the skill set to test properly.

Every finding ships with a working proof-of-concept, a reproduction path, a severity rating with explicit reasoning, and remediation guidance written for the engineers who will fix it.

Capabilities

Targets we test

Each engagement is led by senior operators. Scope is shaped to your environment, not pulled from a template.

01

Application & API testing

Web application, GraphQL and REST API, mobile (iOS/Android), and rich-client desktop application security testing.

02

Cloud & Kubernetes

AWS, Azure, GCP control-plane testing, IAM abuse paths, and container-escape and Kubernetes hardening review.

03

Network & internal

External and internal network testing, Active Directory and identity-tier testing, and lateral-movement assessment.

04

Embedded & OT

Firmware, IoT, automotive, and industrial control system testing — including hardware teardown when scope allows.

05

Source code review

Hands-on code review for high-stakes codebases. Cryptographic flaws, deserialization issues, and authn/authz logic bugs.

06

Vulnerability research

Targeted zero-day research and exploit development for products you ship or technology you depend on.

Engagement flow

How we run it.

A consistent rhythm whether the engagement is a single audit or a multi-quarter program.

PHASE 01

Scope

Targets, depth, and rules of engagement scoped against business risk and the systems you actually care about.

PHASE 02

Test

Hands-on testing by senior operators. Working PoCs, reproduction paths, and detection guidance for every finding.

PHASE 03

Report

Severity with reasoning, technical detail for engineers, and an executive-readable summary for risk owners.

PHASE 04

Re-test

Free re-test of remediated findings within engagement window. We sign off only what we have re-validated.

FAQ

Common questions.

If yours isn’t here, the hotline and engagement intake both reach a senior partner.

How is this different from your cyber warfare service?

Cyber warfare emulates an adversary against your detection and response capability — broad scope, business objectives, blue team tested. Offensive security goes deep on a specific target — narrow scope, technical objectives, vulnerabilities found and fixed. Most clients use both.

Can you find zero-days?

Yes — that is what our vulnerability research team does. Engagements are scoped against specific targets and timelines. We disclose responsibly, including coordinated disclosure with vendors.

Do you do CREST-aligned testing?

Yes. Versus is CREST-aligned and our methodology meets CREST, OSSTMM, and PTES standards where clients require formal alignment.

Can we get a quick web application test?

We do focused application tests on tight timelines. We will not run automated-scanner-only "pen tests" — we do not staff for that and the output does not move risk.
