Offensive Security · Red Team · Adversary Simulation
Crow's Nest Group delivers specialized red team and penetration testing services to GRC consultancies, managed security providers, and cyber insurance brokers — so you can offer your clients the technical depth they require without building it in-house.
Why Crow's Nest Group
They need to know whether an adversary can actually get in. That's where we come in. We work quietly behind the scenes — as your white-label technical arm or a trusted referral partner — so your client relationships stay intact and your service offering expands without adding headcount.
Offensive methodologies aligned to MITRE ATT&CK across every engagement.
Reports delivered under your brand. Your client relationship stays yours.
Subcontract, referral, or co-delivery — we fit how you work.
Cleared professionals with military, government, and private sector experience.
What We Do
Every engagement is scoped, authorized, and executed with one goal: give your clients an honest picture of their risk — and the evidence to act on it.
We replicate the tools, tactics, and procedures of real threat actors — from initial access to data exfiltration — to test whether your client's defenses hold up where it counts.
Internal and external assessments that go beyond automated scanning. We identify what's actually exploitable and what the impact would be.
Thorough manual testing to surface logic flaws, authentication weaknesses, and injection vulnerabilities that scanners routinely miss.
We test LLM-based systems for prompt injection, model abuse, data leakage, and safety control bypass — a capability very few firms offer today.
Assessments for operational technology environments — from IT/OT segmentation reviews to full ICS penetration testing for critical infrastructure clients.
We combine physical security testing with cyber operations to assess the full attack surface — ideal for data centers, government facilities, and regulated industries.
We map what's exposed before an attacker does. Available as a standalone assessment or recurring subscription.
Simulated phishing operations with full metrics and access reporting — click rates, credential harvesting, and post-click behavior.
Collaborative sessions that strengthen defensive teams by working alongside them. Tabletop exercises help leadership understand risk without a live engagement.
Training
Our training programs are designed for individuals, teams, and organizations that want to develop real offensive and defensive security skills — taught by operators who've done the work in the field.
Hands-on training covering core penetration testing concepts, tooling, and methodology — built for individuals pursuing certifications or breaking into offensive security.
Structured curriculum covering adversary simulation, C2 frameworks, lateral movement, and evasion techniques for security teams looking to build internal red team capability.
Collaborative sessions that run attack scenarios in your environment while your defensive team tunes detections in real time. Leaves your SOC stronger after every session.
Role-based awareness programs covering phishing, social engineering, and insider threat — tailored to your organization's risk profile and delivered to staff at all levels.
Scenario-driven exercises for leadership teams to stress-test incident response plans, understand business impact, and build confidence in decision-making under pressure.
Practical training on identifying and exploiting AI system vulnerabilities — prompt injection, model abuse, and data leakage — for teams deploying or securing LLM-based applications.
Key Personnel
Founder & Lead Red Teamer
Ymir Eboras is a former U.S. Air Force officer and red teamer with over 10 years of experience in offensive security. He has led adversary simulation, penetration testing, and security assessments across government and private sector environments, and founded Crow's Nest Group to deliver that same operational capability to organizations that need it most.
About Us
Crow's Nest Group was built on a simple premise: most organizations don't need another compliance report — they need to know whether they can withstand a real attack.
We are a specialized offensive security firm offering red team, penetration testing, and adversary simulation services to organizations that take security seriously. Our team brings experience across military, government, and private sector engagements — applying disciplined, methodical tradecraft to every mission.
We operate with a partner-first mindset. Whether you're a GRC firm that needs technical testing to back your compliance work, an MSSP expanding your service catalog, or an insurance broker who needs to verify client controls before policy issuance — we are built to work alongside you.
We only take engagements we're authorized to perform, and we operate within clearly defined rules of engagement.
We run a small number of engagements at a high standard — not a factory.
Our reports are written for action, not for filing.
