Getting red teaming right

Giles Inkson at NetSPI explains the importance of Red Teaming and how to avoid getting it wrong

 

In today’s cyber landscape, Red Teaming has quickly gained traction as an advanced security practice. With criminals employing ever more sophisticated methods, organisations often face pressure to increase their defences. 

 

Red teams, groups of ethical hackers tasked with simulating real-world threats, sound like the perfect solution. Yet there is a hidden pitfall: many organisations jump into Red Teaming prematurely, lacking the required security maturity to benefit meaningfully from it. 

 

Rather than revealing insights that drive improvements, these exercises can instil false confidence and leave real vulnerabilities unaddressed. Here’s why Red Teaming can go wrong and how businesses can avoid these traps.

 

The maturity paradox

A widespread misconception is that Red Teaming suits any organisation, regardless of its current defensive capabilities. This resembles a novice boxer stepping into the ring with a champion. Without a solid foundation in essential security measures, an organisation cannot hope to gain any meaningful value from advanced testing.

 

Instead of gaining practical insights, immature security teams may feel demoralised when faced with sophisticated simulations they are not equipped to handle. Suppose the underlying patch management process is disorganised or employees lack awareness training. In that case, the results of a Red Team engagement will not tell you anything you did not already know. Worse still, the organisation might interpret a single missed attack vector as conclusive evidence of a robust overall defence, disregarding its weaknesses’ root causes.

 

The intelligence-driven revolution

Red Teaming is often appealing because it promises to mimic genuine cybercriminal behaviour. However, all too many organisations opt for a generic ‘one-size-fits-all’ exercises. These standardised simulations rarely reflect the threat landscape and can create misleading comfort levels.

 

Effective Red Teaming, by contrast, should be intelligence driven. This means spending time, sometimes up to three months, researching the organisation’s specific risk profile, regulatory requirements, and industry context. For example, a financial institution’s threats differ from those that a healthcare provider might face. The Red Team can craft more authentic scenarios by pinpointing these unique risks. They may involve social engineering, clever phishing ploys, physical infiltration, or other tactics designed to replicate the methods used by the most likely adversaries.

 

This intelligence-led approach is not merely about comprehensiveness but about relevance. When the scenarios resonate with the organisation’s genuine weaknesses, the resulting reports contain actionable recommendations. You are far more likely to learn where your defences truly stand and address those vulnerabilities in order of priority.

 

The reality gap

Another pitfall is the ‘reality gap’ between running tests and how the organisation functions in day-to-day operations. In many instances, Red Teaming is carried out under artificial conditions. For example, specific ‘crown jewel’ systems might be exempt from testing, or real-world user behaviour is never considered. The result is a set of lessons that sound compelling on paper but fail to reflect organisational life’s fluid, unpredictable reality.

 

Overconfidence becomes a real threat here. Decision-makers may glance at a successful simulation without realising those key assumptions, such as limited system access or time-restricted testing windows, have significantly reduced the relevance of the findings. 

 

Furthermore, a standard testing blueprint might highlight perimeter vulnerabilities but neglect the very real risk of insiders or supply-chain partners. If these scenarios are not included, the organisation can walk away believing it is prepared when, in fact, some of the most plausible infiltration routes remain untested.

 

Striking the right balance

So, how does an organisation avoid these pitfalls and set itself up for a successful Red Teaming experience? The key is striking a balance between eagerness to improve security and recognition of the foundational steps that must come first.

1. Build a security baseline: Put your house in order by carrying out routine vulnerability scans, staff training, and penetration tests. That way, when introducing a Red Team, you gain advanced insights rather than a list of basic vulnerabilities.
2. Invest in intelligence: Study your threat landscape before commissioning an engagement. Whether you look at emerging malware trends, regulatory requirements, or your sector’s common blind spots, a thorough intelligence-gathering phase ensures your tests align with reality.
3. Keep scenarios realistic: Resist confining a Red Team exercise to contrived or overly controlled conditions. Mirror authentic attacker methods, whether these involve lateral movement in your network, supply-chain threats, or physical infiltration attempts.
4. Interpret findings in context: After the Red Team finishes, work collaboratively with them to translate technical findings into practical security improvements. If you read their report and file it away, the effort will have been wasted.
5. Maintain momentum: Finally, recognise that cybersecurity is not a ‘one and done’ exercise. Red Teaming should be repeated periodically or whenever significant environmental changes occur. Threat actors evolve, and your defences must keep pace.

 

Real gains from Red Teaming 

Red Teaming can be a powerful way to sharpen your organisation’s cyber defences, but only if approached with eyes wide open. Rushing into sophisticated adversarial simulations without attaining a degree of security maturity often does more harm than good, creating a false sense of resilience while leaving core weaknesses unresolved.

 

By carefully aligning testing scenarios with your risk profile, ensuring the simulations reflect real-world operations, and interpreting results thoughtfully and measuredly, you can turn Red Teaming from an expensive vanity exercise into a genuine driver of security evolution.

 

Effective Red Teaming is not about theatrics or ticking a compliance box. It is about understanding your vulnerabilities and improving your overall security posture. When adequately executed, Red Teaming offers the crucial reality check you need to stay one step ahead of determined cybercriminals, safeguarding your digital assets and your organisational reputation.
