Defensive Security delivers high-quality cyber security services including Linux / Windows digital forensics, incident response, latest threat analysis, and hunting, penetration testing, and infrastructure hardening. We successfully deliver a combination of Threat/Adversary Emulations vs network/endpoint investigations and log analysis at scale which is known as Purple Teaming. Defensive Security offers advanced, hands-on cyber security training programs backed by PurpleLabs - a fully customized Cyber Range Environment enriched by step-by-step offensive/defensive lab instructions. Want to sharpen your Purple team skills? Try PurpleLabs where you will be playing with chained attack paths, emulating attacker's TTPs, and running detection/response at the same time by using Sysmon and EVTX, Auditd, Wazuh, Graylog, HELK, ElastAlert, Falco, OSQuery, Velociraptor, Zeek, Suricata, Moloch FPC, Volatility Framework, theHive, MISP, and Sigma Rules. Our mission is to help organizations have more secure infrastructures, better utilize Open Source software in Security Operations, and enable businesses to improve the detection capacity and skills of their SOC/IR teams. We are trusted by the biggest customers from the private, oil and gas, insurance, and financial sector. It was an honor for us to conduct training workshops during the biggest conferences including Hack In The Box, BruCON, 44CON, OWASP AppSec US, and Black Hat US. Our almost 20 years of hands-on experience with Open Source Security Solutions go directly into the full spectrum of technology solutions to support customers achieving better visibility and detections, improving offensive and defensive Red / Blue and Purple team skills, validating defensive technology stacks, and helping understand the value of the Assume Breach approach and emulation of threats after getting initial access (C2, post-exploitation, Lateral Movement, Persistence, Evasion).
