AI Security · Adversary Simulation · Threat-led engineering

Offensive engineering built on real threats.

We don't run on checklists. We replicate real attacker behavior.

Red team practitioners. Proprietary engine, proprietary C2, payloads per scenario — from ransomware to LLMs, AI agents, MCP and OAuth.

Test your resilience

No slides. No sales rep.

Your security looks good on paper. We test whether it actually holds under attack.

"We spent millions on security tools. How much of it actually works during an attack?"

A vendor demo shows a controlled scenario. An attack simulation shows which controls actually detected the threat, which stopped it, and which did nothing at all.

"The board asks: are we secure? I have a certificate — or proof from a real test."

A certificate confirms compliance. It doesn't confirm resilience. A controlled simulation shows the attack path, team response, time to detection, and the specific gaps to close.

"We have AI models in production. Who verified that the protective mechanisms actually work?"

A classic security test often doesn't cover prompt injection, data exfiltration through AI tools, policy bypass, or permission abuse. A simulation tests these scenarios in practice.

"An employee connected an AI tool to M365 via OAuth. Who has access to our data now?"

An AI tool can become an uncontrolled third party with access to corporate systems. We test these scenarios before they become an incident.

We don't deliver another maturity report. We deliver proof: what was detected, what was stopped, what slipped through unnoticed, and what needs to be fixed first.

Most teams only do this after an incident.

By then it's too late.

Four outcomes you get from a project.

01

You see how an attacker gets in.

You see the exact path — every control bypassed, every alert that didn't fire.

02

You know if you'll see the attack.

We test every step of the attack path in your environment — which techniques your SOC notices, which trigger response, and which pass unnoticed.

03

Your SOC knows what it can't see.

You get blind spots mapped to MITRE ATT&CK — with missing telemetry for each.

04

You get proof, not a PDF.

Attack path video. Timestamps. Logs. What your tools saw. What they missed.

We start with attack scenarios, not compliance checklists.

A single test goes stale quickly. The environment changes, and attackers change their techniques. That is why we work in a loop: regular simulations, current threat scenarios, SIEM integration and continuous detection tuning.

01

Attack Simulator — proprietary post-breach engine with 100+ TTPs

Part of services: AI Security Lab, Adversary Simulation

Threat-Informed Defense Purple Teaming SIEM Automation MITRE ATT&CK Coverage

Most teams validate EDR, SIEM and SOC against checklists, vendor documentation or canned scenarios. We validate them against real attacker techniques.

1Strike has its own simulation engine with a library of 100+ techniques for Windows, Linux and macOS, mapped to MITRE ATT&CK. Each technique generates signals that EDR/XDR, IDS/IPS or SIEM should detect.

Scenarios reflect the sequence, timing and conditions of a real attack. We use ready threat actor profiles or write procedures for a specific environment. We run our own code, with a full audit trail of every step: when, who, what and how.

02

Pentest flow — from test to deployed fix

Part of services: Attack Surface Validation

Recurring Validation SDLC Security Pentest Workflow Management and Reporting

A classic pentest ends with a PDF. Findings then land in a backlog and wait for weeks before anyone starts closing them. We run the process from test planning to deployed fix.

Planner structures the scope based on assets and threat profile. Executor supports test execution: operators, schedule, artifacts and evidence from each phase. VM management connects the testing infrastructure and integrates with Jira or ADO.

Outcome: shorter time from request to report, consistent quality, every finding linked to evidence and an attack path. The IT team gets a ticket with context, not a line in a PDF. Leadership sees progress and control effectiveness.

Services — Adversary Simulation

We simulate real adversary behavior — on our own engine, with our own techniques.

We build every project from ready-made simulation modules or design it from scratch for your environment. We use our own 1Strike engine, a threat actor profile, TTP techniques and a scenario tailored to your infrastructure and industry.

Execution mode

We run the simulation in one of two modes. The choice depends on the goal: building blue team capabilities or measuring real detection readiness.

Purple mode — transparent

Your blue team is involved from the start. Each technique execution is verified together in real time. The optimal mode for improving detection and building team capabilities.

Red mode — covert

The attack is hidden from the defense team (internal or SOC provider). This mode measures real detection and response capability, and supports crisis and table-top exercises.

What you get
  • Full attack path with timestamps, logs and artifacts
  • List of bypassed controls with technical justification for each
  • You see exactly what, when and how it was done
Services — AI Security Lab

AI with access to data and tools is a new attack surface.

Companies are deploying AI assistants, agents and automations that connect language models to internal systems, data and tools. Often faster than the security model around these deployments matures.

We don't test the model. We test your actual deployment — in the context of your architecture, industry and risk profile.

We assess agents, assistants, integrations, permissions and data flows. We use our own testing platform and a library of techniques for AI systems: prompt injection, tool-use abuse, exfiltration through RAG, privilege escalation through agents.

What you get
  • List of confirmed attack vectors in your environment — what could be bypassed, exploited or extracted. We describe each vector by business impact, not just the technique.
  • Risk-based assessment of your AI systems architecture — where permission boundaries don't hold, where an agent can perform unwanted actions, and where data leaves the intended flow.
  • Concrete implementation recommendations — what to change in configuration, permissions, integrations and monitoring. With priorities: now, next sprint, long-term monitoring.
Services — Attack Surface Validation

Finding a vulnerability is the start. Closing the loop from test to deployed fix — that's the difference.

Most organizations test their attack surface once a year, sometimes twice. The output is a PDF with hundreds of findings that land in a backlog and stay there for quarters. Before anything gets fixed, the environment shifts, vulnerabilities go stale, and the next test starts from scratch.

The client doesn't buy a report from us — they buy a process that shortens the time between finding a vulnerability and deploying the fix.

We validate your attack surface continuously, not once a year. We run scoping through our platform, reporting and vulnerability management happen in one workflow — with integration to your Jira, ADO, EDR. We use our own tooling stack built for this cycle.

What you get
  • Continuous validation, not an annual snapshot
  • One workflow instead of five disconnected tools
  • Short list with confirmed exploitability

Before we talk

We work best with teams that already have EDR, SIEM, SOC or MDR and want proof that their controls work under real attack pressure.

We also help organizations deploying AI/LLM systems in production that need evidence that agents, integrations, permissions and guardrails work in practice.

This is especially relevant when cybersecurity is part of the value you promise your customers — or when you are preparing for DORA TLPT, NIS2 art. 21, cyber insurance renewal, or a board-level discussion about control effectiveness.

The first call. No slides. You talk to the person who will run the project.

We are probably not the right fit if you are still building your first controls, have no internal security function, or only need help passing a compliance audit. Write anyway — we will point you to someone who does that well.
