Collaborative threat simulation

Purple teaming bridges the gap between offensive and defensive security by creating a collaborative environment where red and blue teams work together to detect, respond to, and mitigate advanced threats in real time.

SilentGrid's purple team engagements focus on adversary emulation, simulating sophisticated attack techniques while actively engaging your defensive teams and SOC analysts. Each exercise identifies detection gaps, refines response processes and keeps your security infrastructure continuously evolving against emerging threats.

Purple teaming is not a one-sided attack simulation. It is a transparent, iterative process designed to uplift your people, processes and technology, so your defences mature with each engagement.

Objectives and outcomes

Enhance detection capabilities

Improve your ability to identify sophisticated attack techniques across all phases of the kill chain

Validate security controls

Test and tune EDR, SIEM, and other security tools against real-world attack scenarios

Improve response times

Reduce mean time to detect (MTTD) and respond (MTTR) through hands-on practice

Upskill security teams

Provide practical, real-world training to SOC analysts and incident responders

Is purple teaming the right fit?

Purple teaming works alongside a defensive team, so there has to be one to work alongside. Where detection and response are mature enough to be tested without warning, red teaming measures them covertly instead.

Purple teaming is ideal for organisations that

  • Have an established SOC or blue team that wants to improve detection and response.
  • Want to know whether their EDR, SIEM and logging catch the techniques used against their sector.
  • Want their analysts to work directly with offensive operators and see how attacks are run.
  • Need evidence that detection has improved, technique by technique, for leadership or audit.

Purple team methodology

SilentGrid's methodology mirrors real-world attack chains while ensuring full collaboration across all phases of the engagement.

  1. 01

    Engagement planning and threat modelling

    • Jointly define objectives, adversaries, and target environments
    • Select specific tactics, techniques, and procedures (TTPs) based on industry threats and past incidents
  2. 02

    Adversary emulation and initial testing

    • Simulate targeted attacks aligned with the MITRE ATT&CK framework
    • Baseline existing detection capabilities to identify immediate gaps
  3. 03

    Real-time collaboration and detection

    • Execute attack techniques while blue teams monitor in real-time
    • Provide immediate feedback on detection successes and misses
  4. 04

    Iterative refinement

    • Replay attacks with modified detection rules and response procedures
    • Validate improvements and identify remaining blind spots
  5. 05

    Process enhancement

    • Update incident response playbooks based on lessons learned
    • Train SOC analysts on advanced detection techniques
  6. 06

    Knowledge transfer and documentation

    • Deliver comprehensive documentation of all techniques tested
    • Provide actionable recommendations for long-term improvements

Run it continuously

Tune it once, or replay it every cycle.

A single purple team exercise baselines your detections and tunes the rules behind them. Where the environment keeps changing, CAOS (Continuous Adversary Operations Service) runs red team cycles through the year, and each cycle can close with a purple team replay of its techniques.

Why SilentGrid

SilentGrid's consultants are hand-picked, and between them they have delivered red team engagements globally over decades, including CBEST for UK financial institutions and CORIE engagements in Australia. Their sector experience covers banking and financial services, insurance, government, critical infrastructure and healthcare.

Consultants find 0-day vulnerabilities in commercial software and speak or teach at security conferences. That research produces the custom tooling used to bypass EDR and network controls, and keeps techniques current with the threat actor being simulated. The methodology follows concepts set out in NIST, OWASP, PTES and OSSTMM.

Common questions

What is purple teaming?

Purple teaming tests detection and response the way an attacker would, with the defenders watching: operators execute adversary techniques aligned with MITRE ATT&CK while your SOC analysts monitor, detection successes and misses are fed back as they happen, and attacks are replayed against modified detection rules. The result is a documented detection gap analysis and tuned detections.

What does a purple team engagement test?

Whether your SOC and security tools detect and respond to specific adversary techniques. Operators run each technique alongside your analysts, record what was caught and what was missed, and run it again once detection rules or response steps change.

How is purple teaming different from red teaming?

Red teaming works covertly towards an agreed business objective and tests whether your defences notice. Purple teaming is transparent and collaborative: techniques are executed alongside your defenders and replayed to tune detection rules.

What do we need in place to run one?

A SOC or blue team to work alongside. Purple teaming suits organisations with established security teams looking to improve detection and response; scope and intensity are tailored to your defensive maturity.

How long does a purple team engagement take?

One to four weeks is typical, with scope and intensity aligned to your defensive maturity.

Can purple teaming run as an ongoing program?

Yes, in two ways. In an annual program, purple team sessions run alongside the adversary campaigns, either as two longer sessions a year or four shorter ones, and the cadence can change at any quarterly planning session. In CAOS (Continuous Adversary Operations Service), the TTPs used in a cycle can be replayed with your security team before the next cycle begins, together with techniques current threat actors use. That replay is optional, up to two a year, and a whole cycle can also be dedicated to purple teaming.

How is improvement measured?

By running the same techniques again after detection rules or response steps change, and recording which are now detected and how long your team took to respond and contain them (MTTR). The detection gap analysis maps those results to MITRE ATT&CK, so coverage before and after tuning can be compared. In a CAOS program, HackTrack (SilentGrid's platform for operator logs, indicators of compromise and the techniques used) holds the data from every cycle and purple team.

What do we receive at the end?

Attack technique documentation, a detection gap analysis, detection rule guidance, response playbook updates, training materials and an executive briefing.
