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 resilienceNo slides. No sales rep.
Problem
"We spent millions on our security stack. How much of it actually works under attack pressure?"
Vendor demos show the happy path. Auditors check control existence, not effectiveness. SOC counts closed tickets, not missed attacks.
"The board asks: 'Are we secure?'. I have a certifications slide — or evidence with a timestamp."
A certificate on the wall shows compliance, not resilience. Real proof is the attack path, the controls that failed, and the remediation plan — that's how you defend your 2027 budget.
"We have LLMs in production. Has anyone actually verified the guardrails work — or do developers just hope they do?"
Most pentest shops don't know how to test LLMs. EDR doesn't see prompt injection. Writing OWASP LLM Top 10 into your policy protects nobody.
"An employee connected an AI tool to M365 via OAuth. Who has access to our data now?"
Not hypothetical — this is the Vercel incident from 2025. The AI tool became a third party with access to corporate systems that nobody audited.
Most teams only do this after an incident.
By then it's too late.
What we do
You see how an attacker gets in.
You see the exact path — every control bypassed, every alert that didn't fire.
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.
Your SOC knows what it can't see.
You get blind spots mapped to MITRE ATT&CK — with missing telemetry for each.
You get proof, not a PDF.
Attack path video. Timestamps. Logs. What your tools saw. What they missed.
What sets us apart
If your last pentest ended with a PDF — we don't do the same thing.
We're not broader than a pentest shop — we go deeper. We don't automate like BAS. We're not AI-only like a red team boutique. 1Strike is a team of red team and purple team practitioners who have been running attack simulations in real environments for years. We work with our own simulation engine, proprietary C2 and payloads built per scenario. We combine classic offensive engineering with AI/MCP/OAuth testing and TLPT (DORA) readiness.
NIS2 and DORA require proof of control effectiveness, not just their existence. Our tests show what actually works in your environment — and what doesn't.
Validation cycle
Based on our experience, we build the scenario based on current threat intelligence for your industry and tech stack. Specific TTPs, specific adversary profile — not generic "APT".
We execute techniques in your environment. Your blue team participates in parallel — not getting a report after the fact. Together we verify what's visible, what isn't, and why.
We map results to detection and configuration gaps. Your team gets specific changes to implement — rules, playbooks, telemetry. Not a report for the archive.
We replay scenarios after fixes are deployed. We document results as proof of control effectiveness.
Services
Backed by: 1Strike simulation engine
LLMs, agents, MCP, OAuth — tested by a team with 20+ years of offensive engineering background. We don't treat AI as a separate research curiosity. We test it like any other attack surface.
"We have an LLM/agent in production and we don't know how to actually test it."
Confirmed attack vectors in your AI environment — what can be extracted, what unauthorized actions are possible, where boundaries don't hold. Plus specific changes to implement.
Backed by: 1Strike simulation engine
Real TTPs. Proprietary C2. Payloads built per scenario. Delivered by a team that has been running red team, purple team and attack simulation work in enterprise environments for years. We assume the attacker is already inside. We simulate their actions and check how far they can go and what actually stops them.
"We need to verify our SOC will catch ransomware in a real environment." "DORA TLPT readiness." "Post-incident hardening."
Documented breach path mapped to MITRE ATT&CK — every bypassed control, every artifact, every detection gap. Plus retest after fixes deployed.
Backed by: 1Strike Pentest flow + Vulnerability Broker
Targeted testing driven by attack-path logic. Plus vulnerability management and board-level reporting tooling. Similar in form to pentesting — but prioritized by real exploitability, not CVSS alone.
"We have a pentest budget, but want more than a CVE list."
Tested assets and clear remediation priorities. Process planned and reported to the board.
Our philosophy
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.
Part of services: AI Security Lab, Adversary Simulation
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.
Part of services: Attack Surface Validation
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.
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.
We run the simulation in one of two modes. The choice depends on the goal: building blue team capabilities or measuring real detection readiness.
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.
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.
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.
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.
Engagement format
Every organization has different security maturity, a different technology stack and a different way of working. That's why we don't publish pricing. We agree on the format in the first technical call — and that call, not this website, starts the project.
Format depends on where you are. A price list on the site would assume we already know.
Do you have an internal security team, an MDR, or both? Should the blue team be involved in the test, or not see it? That determines the scope and duration of the project.
EDR, SIEM, SOC, identity stack, cloud posture — this determines which techniques (TTPs) are worth testing first and which integrations we run from our platform.
One-time test before an audit, quarterly validation, continuous cycle after a major infrastructure change — each model requires different scope and duration.

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.
