Cybersecurity Teams: Red, Blue, and Purple Explained

Many people have the illusion that cybersecurity is all about hackers and cryptographers. But do you know how cybersecurity firms actually operate from the inside? It’s not just about hackers launching attacks or cryptographers encrypting your data. Just like a sports team, cybersecurity firms divide their engineers into specialized teams.

Think of it like soccer: A team needs both strong strikers to score and solid defenders to prevent opponents from breaching their goal. Similarly, cybersecurity teams are categorized based on their functions:

Red Team – Offensive security (attackers)
Blue Team – Defensive security (defenders)
Purple Team – A hybrid unit that bridges both attack and defense

In this blog, we’ll explore the roles of each team and help you decide which one suits you best if you're stepping into the world of cybersecurity. Let’s dive in!

1) Red Team: The Attackers

Just like the assault team in BGMI or strikers in soccer, the Red Team is responsible for launching attacks on an organization’s digital infrastructure. Their goal is to identify vulnerabilities before real hackers do.

Roles in the Red Team

Penetration Tester (Ethical Hacker): Simulates cyberattacks to find weaknesses in systems.
Social Engineer: Uses psychological tactics to trick employees into revealing sensitive information (e.g., phishing attacks).
Exploit Developer: Creates custom tools or exploits to breach security defenses.
Threat Actor Analyst: Mimics real cybercriminal tactics to test an organization’s resilience.
Physical Security Tester: Assesses physical security measures, such as access controls and facility vulnerabilities.

Required Certifications for Red Team

To join the Red Team, you’ll need certifications that prove your ability to hack ethically and legally. Some popular ones include:

Certified Ethical Hacker (CEH) – Covers penetration testing fundamentals.
Offensive Security Certified Professional (OSCP) – A hands-on advanced penetration testing certification.
GIAC Penetration Tester (GPEN) – Focuses on penetration testing methodologies.
Certified Red Team Professional (CRTP) – Specializes in adversary emulation.
CompTIA PenTest+ – Covers intermediate penetration testing skills.

2) Blue Team: The Defenders

If the Red Team is the offense, the Blue Team is the defense. Their job is to protect an organization's digital assets by detecting, responding to, and mitigating security threats.

Roles in the Blue Team

Incident Responder: Reacts to and contains security breaches.
Security Analyst: Monitors logs and network activity for suspicious behavior.
Forensic Investigator: Analyzes past cyberattacks to prevent future ones.
System Administrator: Strengthens security configurations and applies patches.
Threat Hunter: Proactively searches for undetected threats within a network.

Required Certifications for Blue Team

To enter the Blue Team, you need certifications that validate your defensive skills. Some key ones include:

GIAC Certified Incident Handler (GCIH) – Focuses on detecting and responding to security incidents.
CompTIA Cybersecurity Analyst (CySA+) – Covers threat detection and defense strategies.
Certified Information Systems Security Professional (CISSP) – A comprehensive certification for security management.
Blue Team Level 1 (BTL1) – Covers digital forensics, threat intelligence, and incident response.
GIAC Certified Intrusion Analyst (GCIA) – Specializes in network traffic analysis and intrusion detection.

3) Purple Team: The Collaborators

The Purple Team is a relatively new concept in cybersecurity. Instead of operating as a separate unit, it facilitates collaboration between the Red and Blue Teams to enhance security effectiveness.

Roles in the Purple Team

Purple Team Coordinator: Bridges communication between Red and Blue Teams.
Knowledge Share Facilitator: Ensures findings from Red Team attacks are used to strengthen Blue Team defenses.
Performance Analyst: Evaluates the effectiveness of security exercises.
Tools & Techniques Trainer: Keeps teams updated on the latest offensive and defensive tools.
Strategy Planner: Designs security simulations to test and refine defenses.

Required Certifications for Purple Team

Since the Purple Team requires knowledge of both attack and defense strategies, these certifications can help you transition into this role:

GIAC Defending Advanced Threats (GDAT) – Merges offensive and defensive tactics.
Certified Purple Team Analyst (CPTA) – Specializes in Red-Blue Team collaboration.
ATT&CK® Purple Teaming Certification – Focuses on adversary emulation and defensive improvements.
SANS Purple Team Operations Certificate – A high-level program for advanced purple teaming skills.

Which Team Should You Choose?

Feeling confused about whether you should join the Red, Blue, or Purple Team? Here’s a simple way to decide:

Are you naturally good at attacking or defending in sports or games?
Do you prefer offensive strategies (hacking) or defensive strategies (protection)?
In BGMI, do you play as an assault team member (attacker) or a sniper (defender)?
In soccer, do you play as a striker (offense) or a defender (defense)?

If you enjoy finding loopholes and exploiting weaknesses, Red Team is for you. If you prefer preventing attacks and safeguarding systems, Blue Team is your best fit. Once you gain experience, you can transition into the Purple Team to bridge both sides.

Cybersecurity is a dynamic and ever-evolving field. Whether you choose to be an attacker (Red Team), a defender (Blue Team), or a strategist (Purple Team), each role plays a crucial part in securing the digital world.

So, what’s your pick? Attack or defense? Identify your strengths, work on your skills, and conquer the cybersecurity domain!
