Find what attackerswould actually exploit.
Braintruder is an AI-driven penetration tester that attacks your systems like a real adversary, captures evidence for every step, and turns what it finds into clear, actionable risk - graded against the compliance standards you are measured on. No specialist offensive expertise required.
The problem was never a lack of tools. It was making them work.
SMEs face the same threat landscape as the FTSE 100 with a fraction of the budget, headcount, and specialist depth. Existing options leave them with theatre, not assurance.
- 01Pen-tests are scarce, slow, and expensive.Most SMEs test once a year - if at all. Attackers don't wait twelve months.
- 02Vulnerability scanners flag noise, not risk.A list of CVEs isn't a security posture. Nothing tells you what's actually exploitable.
- 03Specialist talent is unavailable to most teams.Offensive security expertise is locked inside enterprises and consultancies.
- 04Reports become static the moment they're delivered.A PDF from last quarter can't answer “are we still safe today?”
A methodology, not a black box.
Every engagement follows the same disciplined loop. You see what was tested, why, and what we learned.
Scope & Recon
Define targets and rules of engagement. Braintruder maps your surface, stack, and authentication model.
Hypothesise
Forms attacker-style hypotheses grounded in recognised methodology, following OWASP WSTG and the OWASP risk-rating model.
Validate Safely
Tests hypotheses with guardrails and explicit approval gates for any higher-risk action.
Report & Compare
Findings synthesised into evidence-backed reports - and compared against your policies and controls.
Offensive depth, delivered like a tool you actually use.
Human-Style Testing
AI agents that probe like operators, not like scanners - chaining context, not just signatures.
Controlled Exploitation
Simulated exploitation with guardrails. Higher-risk actions are gated behind explicit approval.
Evidence-Backed Reports
Every step, command, and outcome is captured - turning a finding into a defensible artefact.
Methodology-Aligned
Engagements follow OWASP WSTG methodology, map to ISO 27001 and Cyber Essentials controls, and score severity with CVSS.
Policy Comparison
Compare technical findings to your internal policies and recognised standards to surface real gaps.
Built for IT Operators
Designed for system operators and IT teams to run meaningful security testing on their own surface.
Watch a real methodology, not a marketing reel.
Braintruder narrates its work as it goes. You see the hypothesis, the probe, the evidence, and the next decision - the same way a thoughtful operator would walk you through it.
- Transparent reasoningEvery step is logged with intent, target, and outcome.
- Approval gatesHigher-impact actions pause for an operator to confirm.
- Replayable evidenceFindings ship with the artefacts that proved them.
Capabilities shown are illustrative. Braintruder is evolving rapidly - get in touch for the current scope of supported methodologies and integrations.
Not just what's exploitable. Whether you can prove you're secure.
Every engagement does double duty. Braintruder attacks your surface like a real adversary, then grades what it finds against the standards you are assessed on. One test, two answers: what an attacker could do, and where you stand on compliance.
