Purple Teaming is the defensive Blue Team and the offensive Red Team operating together as a single unit. Purple Team cybersecurity practices preparation and detection against malicious tactics (historically Blue Team methods), which are initiated (historically by a Red Team) to test defense in depth. The malicious tactics and techniques initiated are often adapted to mimic specific threats an organization would face in terms of their industry and unique needs.
Traditional penetration tests and vulnerability scanner assessments identify vulnerabilities on systems only for that fragment in time. This is a problem due to constant system changes that regularly happen; a system can become vulnerable at any time. A malicious actor only needs a fraction of a second to compromise a system.
Purple Team cybersecurity initiatives eliminate possible gaps that can appear when proper risk assessment and management aren’t a revolving practice.

Purple Teaming Cybersecurity Goals
Practicing Purple Teaming cybersecurity can improve the overall security of an organization. Simulated malicious techniques help professionals familiarize with the ever-expanding threat environment. For every simulated scenario generated by the Red Team, Blue Teams are required to update their playbooks.
Playbooks determine different types of alerts and include a compilation of routine procedures an administrator carries out. It is standard practice for Blue Team defenders in security operation centers (SOC).
Purple Teaming cybersecurity operations initiate incident responses (IR) to improve security culture processes. Purple Teams can leverage reconnaissance techniques to test the effectiveness of an organization’s security procedures. This better enables employee awareness and adherence to policies — leading to faster detection and stronger threat containment ability.
Open Source Intelligence (OSINT) is a term used to refer to the data collected from publicly available sources. OSINT can be used to gather information like high-profile employee descriptions inside an organization. Some tools used may include:
- Web Scraping
- Data Scraping
- Domain Scraping
- Email Extraction
It is common for DNS servers or controlled mail relays to be externally visible. This is a bad practice for printers, database servers, and out-of-date systems. Through continuous Purple Team exercises, an organization can ensure changes are made to systems allowing only authorized devices to be accessed directly from the internet.
Purple Team cybersecurity operations offer a direct return on investment by identifying cracked processes and procedures. Purple Teamers find gaps in current security stacks, leading to more efficient and effective future purchases.
