Attacker-led
cyber
Advisory
We bring attacker insight to founders, Investors, and boards
We expose the gaps that audits, tools, and assumptions leave behind.
Who We
Work With
Venture
Capital
& Investors
Cyber due diligence that exposes real risks before deals close, not after.
Scale-Ups &
Growing Companies
Cyber uplift and vCISO support to scale securely without slowing down the business.
High-Risk & Targeted Industries
Red team engagements and vulnerability research for organisations that are actively targeted.
The
Attacker-Led
Approach
STEP 1: Start from the attacker’s point of view
We model how real attackers would target your business, technology, and people based on the tools and techniques attackers use.
Step 2: Validate risk in the real environment
We test assumptions and controls to see what holds up under pressure.
Step 3: Turn findings into decisions
Clear, prioritised actions tied to business risks. No reports that never get actioned.
Case Studies
VC-Backed Technology Company
Cyber Due DiligenceEngaged ahead of a strategic investment where cyber risk could materially impact valuation and deal structure.

Assessed the target through an attacker-led lens, validating security posture beyond policy and audit artefacts.
Outcome
Surfaced previously unknown risks that informed deal conditions and post-investment priorities.
Scaling SaaS Company
Cyber Operating Model UpliftRapid growth had outpaced the existing security operating model, decision-making, and internal capability.

Designed the cyber operating model and uplift plan. Provided vCISO support aligned to growth and risk tolerance.
Outcome
Established clear accountability, reduced security noise, and gave leadership confidence in day-to-day decisions.
Multi-National Logistics Company
Red TeamEngaged by the board to validate organisational compliance posture with real-world testing.
What We Did
Simulated realistic attack paths across people, process, and technology to identify how a real compromise would unfold.
Outcome
Demonstrated multiple paths to critical systems and delivered a clear, prioritised remediation roadmap.
How We Compliment Existing Teams
Internal IT Teams
Focused on availability, systems, and day-to-day operations. Security is part of the role, but rarely the only one.
MSP / IT Providers
Responsible for keeping environments stable, supported, and secure at scale. Often constrained by tooling, scope, and commercial models.
Internal Security
Focused on controls, frameworks, and ongoing security programs. Strong on governance, limited time for deep adversarial testing.
Brace Cyber is brought in to challenge assumptions, test real attack paths, and provide independent, attacker-led insight when the stakes are high.
How to get started
The fastest way to understand whether we’re the right fit is a confidential conversation.
We’ll discuss your situation, pressure-test assumptions, and recommend the most appropriate next step.
