Test Your Defences in Realistic Conditions

Apstorm’s Red Teaming service replicates adversary behaviour under controlled, realistic conditions. We expose unseen security gaps before real attackers can exploit them, delivering actionable insights and assurance for CISOs and Threat Intelligence teams.

Real World Cyberattack Scenario

Many security programmes appear strong on paper but fail under pressure. Traditional penetration tests focus on exploiting vulnerabilities, but do not simulate full scale real-world attack chains. Without testing a full scales cyberattack. 

Organisations can face:

  • Overconfidence in detection and response capabilities.
  • Lack of adversary-level perspective on lateral movement and privilege escalation.
  • Limited ability to measure resilience against targeted, multi-phase attacks.
  • Pressure from boards and regulators to validate real risk exposure.

How Red Teaming Helps Secure Your Organisation

Red Teaming engagements emulate targeted adversaries. Combining strategic threat modelling with advanced attack techniques to test your defences across people, process, and technology.

Key strengths include:

  • Custom threat scenarios built on your industry and threat landscape
  • Stealth operations using living-off-the-land, privilege escalation, and covert command and control
  • Defined rules of engagement for safety and realism
  • Comprehensive reporting with executive summaries, kill chain mapping, and remediation roadmaps
  • Optional purple teaming to validate and harden detection and response

Red, Blue and Purple Teaming

We design exercises around your business objectives: break in, stay hidden, reach impact, then turn every step into defender uplift.

Red Teaming

Blue Teaming

Purple Teaming

Red Teaming: 

Multi-vector, covert operations across external, internal, social and physical avenues. We emulate relevant threat actors, chain weaknesses and pursue defined objectives like data exfiltration or domain dominance.

Blue Teaming:

Collaborative defence: log source review, detection engineering, threat hunting and incident response practice focused on the exact TTPs used.

Purple Teaming:

Structured attacker – defender pairing, where each attack step is immediately translated into telemetry checks, analytic rules, response actions and re-tests, raising MTTD and MTTR within the same engagement.

Key Benefits
  • Validate real-world resilience with proof of exploitation
  • Reveal complex attack paths missed by traditional testing
  • Strengthen executive confidence with clear risk narratives
  • Improve detection and response through follow-up purple teaming
  • Align security investments with real attack behaviours

FAQ's - Read Teaming

Q1: How is this different from a penetration test?

A: A traditional pentest focuses on finding vulnerabilities at a point in time. Red teaming pursues realistic objectives using chained TTPs over weeks. Purple teaming turns each step into defender improvements during the engagement, not after. This collaborative model is widely recommended in the market.

A: Yes. Red team exercises can be fully covert to test detection and response truthfully, including social and physical components where in scope.

A: No. We work within defined Rules of Engagement and coordinate closely with stakeholders to ensure safety. 

A: Yes. Scenarios are built around your sector’s threat landscape and known actor behaviour.

A: We can align scenarios, artefacts and reporting to Threat-Led Penetration Testing (TLPT) frameworks and work alongside your regulator or lead overseer as required.

A: It’s available as a follow-on service to validate and improve defensive measures.

A: You receive a full report, attack chain diagrams, and a prioritised action plan. We also support remediation as needed.
