Unify Your Offense and Defense. Validate What Actually Works.
Most organizations run Red Team exercises and Blue Team defenses in isolation. The Red Team finds gaps. The Blue Team never learns why their tools missed it. The cycle repeats and real attackers keep winning. GLI Secure’s Purple Team Services break that cycle.
We bring your offensive and defensive security teams together in a continuous, collaborative exercise that turns attack simulations into measurable security improvements in real time, against your actual environment.

Introduction
What Is Purple Teaming?
A Purple Team engagement is a structured collaboration between offensive security specialists (Red Team) and your defensive security operations (Blue Team).
Rather than the Red Team attacking in secret and delivering a findings report weeks later, Purple Teaming runs both functions together, with full communication, shared visibility, and immediate feedback loops.
The Red Team quickly finds the critical gap in the system's defenses.
GLI Secure ensures the fix is implemented and verified before the engagement ends.
Blue Team learns exactly why they missed it and how to improve next time.
Why GLI Secure
The GLI Secure Purple Team Difference
Gaming-Regulatory Aware
Real-Time Knowledge Transfer
Your Blue Team watches every technique as it executes. We narrate, explain, and teach, turning a one-time exercise into a permanent capability uplift.
MITRE ATT&CK Mapped
Every technique is mapped to MITRE ATT&CK framework entries, giving your SOC team detection coverage metrics they can report to regulators and boards.
Social Engineering Specialisation
We replicate the exact Scattered Spider methodology used in the MGM/Caesars attacks—including vishing, MFA fatigue, and IT help desk impersonation—with your live staff in a controlled exercise.
Verification, Not Just Discovery
We don’t hand over a report. We stay until every critical finding has a verified detection or remediation in place. Your security posture measurably improves before we leave.
how we help
We bring deep expertise to every engagement, backed by an understanding of the unique threat landscape facing global industries. As organizations embrace technological innovation, they also face increased exposure to social engineering attacks and other forms of cybercrime.
How It Works
Our Purple Team Methodology
Every GLI Secure Purple Team engagement follows a structured, six-phase methodology designed to maximize Blue Team learning while maintaining rigorous offensive tradecraft.
Scoping & Threat Profiling
Your vCISO owns the security programme, not just advises on it. They build or inherit your security roadmap, set priorities aligned to your business objectives and risk tolerance, manage your security budget and technology investments, and track programme progress against measurable outcomes.
- Define in-scope systems, networks, and personnel
- Build a threat actor profile relevant to your gaming segment and jurisdiction
- Agree on rules of engagement and emergency stop procedures
- Identify Blue Team participants and establish communication protocols
Intelligence Gathering & Attack Planning
- OSINT reconnaissance of external attack surface
- Social media and LinkedIn profiling of IT and security personnel
- Attack scenario development mapped to MITRE ATT&CK
- Blue Team receives advance notification of attack scenario categories (not techniques)
Collaborative Attack Execution
This is where purple teaming diverges from traditional Red Team exercises. Attacks are executed with the Blue Team observing — either in the room or through a shared secure collaboration platform. After each technique, we pause for a structured debrief: Did you detect it? What did your SIEM show? What would have caught it?
- Live attack execution with blue team observation
- Immediate post-technique debrief and detection gap analysis
- SIEM, EDR, and network log review in real time
- Detection logic developed and tested on the spot
- Social engineering simulations (vishing, phishing, MFA fatigue) with staff participants
Detection & Response Uplift
For every technique that was not detected or incorrectly alerted, GLI Secure works directly with your Blue Team to build or improve detection logic in your existing security tooling. We do not prescribe new tools — we maximize what you already have.
- SIEM rule development and testing for undetected techniques
- EDR tuning and alert threshold adjustment
- Runbook and playbook development for newly detected attack patterns
- IT help desk policy hardening for social engineering defences
Verification Testing
Before the engagement closes, every improved detection is verified with a repeat execution of the original technique. This creates a before/after comparison that demonstrates measurable improvement — critical for gaming regulatory compliance documentation.
- Re-execution of all previously undetected techniques
- Side-by-side comparison of original vs. improved detection rates
- Documentation of verified detection coverage for regulatory evidence
Executive Reporting & Roadmap
GLI Secure delivers a comprehensive Purple Team Report formatted for three audiences: technical (SOC team playbooks and detection rules), operational (CISO security programme evidence), and executive/board (plain-English risk reduction narrative).
- Technical report: all techniques, MITRE ATT&CK mapping, detection rules, playbooks
- Compliance report: findings mapped to your gaming regulatory cybersecurity requirements
- Executive brief: risk-quantified summary formatted for board and gaming regulator presentation

Ready to Validate What Actually Works?
A Purple Team exercise is not a pass/fail test. It is a capability-building investment that leaves your security team measurably stronger than when we arrived. For gaming organizations operating under regulatory cybersecurity requirements, it also generates the compliance evidence your gaming regulator, cyber insurer, and board need to see.
