Adversary Simulation
Adversary Simulation & Red Teaming
For CISOs and security leaders preparing for high-stakes threat testing. We deliver full-spectrum adversary simulation mapped to MITRE ATT&CK, using threat intelligence to emulate complex attackers and validate detection and response.
Overview
Threat Intelligence-Led, Business Impact Focused
Operational resilience depends on anticipating, withstanding, and recovering from realistic cyber disruption. Threat-led testing provides a golden thread from credible intelligence to business impact.
We scope to important business services and the people, process, and technology that support them, then emulate complex threat actors to validate detection and response. We also simulate privileged insider and supply-chain scenarios to test controls inside the network, not just at the perimeter.
We deliver adversary simulation, red team operations, and threat-led penetration testing (TLPT). TLPT can be delivered as a standalone engagement or as a staged pathway into full red team operations. Engagements are scoped to business risk and delivered with clear metrics, prioritized remediation, and executive-ready reporting.
Why Atlan
Threat-Led by Design
We build scenarios from current and credible threat intelligence, then map them to MITRE ATT&CK and to your important business services. Our operators emulate complex threat actors and chain multi-stage attack paths that mirror real-world intrusion tradecraft.
Senior Operator-Led Teams
We operate a contractor-led model and provide consultant profiles for review and approval, allowing teams to be tailored to each engagement. We are not an accredited CBEST/TBEST/TIBER-EU provider, but our operators have delivered those engagements for years and bring that discipline into every simulation.
NATO DIANA Shortlisted
Turul GAN was NATO DIANA shortlisted and has been discussed with multiple ministries of defence and a small number of defence primes. Our R&D keeps tradecraft current and supports high-fidelity simulation. Explore our R&D program.

Cyber High-Level Methodology
Mapped to MITRE ATT&CK. We typically follow a six step model working from out to in, to fully assess operational impact.
1. Recon
Profiling, SharpInfo Pretexts, OSINT
2. Exploitation
Phishing, EDR Evasion, Command Execution and C2 Callback
3. Privilege Escalation
Active Directory Enumeration, Workstation & Network Share Enumeration – patch levels, password policy, file shares, ADCS
4. Lateral movement
SharpHound, AzureHound, Certify, WinRM, RDP, AdXplorer, SharpML, SharpSniper.
5. Persistence
Registry, WMI, VPN, Scheduled Tasks, COM, ‘Living off the land’, DMZ Web Shells.
6. Operational impact
Comprehensive Reporting and Presentation around business and operational impact.
Outcome Focus
Threat-Led Outcomes, Not Checkbox Testing
Every engagement is scoped to business risk and delivered with clear metrics, prioritized remediation, and executive-ready reporting.
Case Study (Anonymised)
TIBER-EU Preparation for a European Stock Exchange
We supported a European mainland stock exchange in preparing for a TIBER-EU assessment through a multi-step engagement:
- Frontal assault to validate perimeter resilience.
- Phishing and MITM exercises to test detection and response.
- Assumed compromise scenarios to emulate realistic attacker dwell time.
The engagement surfaced novel attack paths into important business services and provided a prioritized remediation roadmap.
