DEFENDER OPERATIONS, ENGINEERED
We build your defense.
Then we try to break it.
InfoSec Builder designs, validates and runs security operations for teams that can’t afford to learn in production, SOC programs, adversary simulation, and hands-on intrusion analysis & digital forensics training.
- SOC Building
- Penetration Testing
- Red & Purple Teaming
- SIEM Use Cases
- Incident Response
- Hands-on Training
WHAT WE DO
Security services across the whole defender lifecycle
From standing up detection programs to attacking them the way adversaries do, one practice across engineering, validation and skills.
01
SOC Building
Architecture, people, process and tooling for a detection program that runs without a hero.
02
Penetration Testing
Scope-driven offensive testing of apps, networks and cloud, findings you can actually fix.
03
Red & Purple Teaming
Objective-based adversary simulation that exercises the whole defense, not just the perimeter.
04
SIEM Use-Case Management
Detection content mapped to the threats you care about, tuned, maintained and measured.
05
Tabletop Exercises
Decision rehearsals for the moments that matter, with the people who would actually run them.
06
Incident Response
Containment, analysis and recovery support when something is already inside.
HOW WE WORK
Assess. Build. Attack. Learn.
One operating loop, applied to whatever stage your security program is at.
Assess
A short, focused engagement to map your attack surface and the gaps in your detection and response.
Build
We engineer what’s missing, SOC model, detection content, playbooks, process, sized to your team.
Attack
Pentests, red & purple teaming and tabletops validate defenses the way adversaries actually behave.
Learn
Hands-on labs and exercises embed the lessons, so the capability stays after the engagement ends.
Training that changes how analysts think
Our labs are built from real intrusion cases. You don’t watch slides, you investigate a compromised machine, trace the attacker’s moves, and write the detection that catches them.
- Hands-on intrusion analysis, hunt, triage and reconstruct real attack chains
- Digital forensics foundations: memory, disk, network and malware triage
- Detection engineering on real log sources, not sanitized toy datasets
- Mentored remote tracks and team sprints, with before/after skill assessment
