Factor four: Detection speed can determine business impact

The sooner an attack is identified, the greater the opportunity to contain it before it spreads across the network. Continuous monitoring, behavioural analytics and well-rehearsed incident response procedures all play an important role in reducing operational disruption.

Regular tabletop exercises also help ensure technical teams, executives and communications teams understand their responsibilities during a major incident.

Frank Vukovits, Chief Security Scientist at Delinea, says:“ The volume of threat signals modern environments generate has long passed the point where human analysts can review them manually. There are simply too many needles in too many haystacks.

“ This is where AI-powered detection earns its place, sifting the full universe of signals to surface the patterns that indicate an attack is underway, so your Security Operations Centre can act on what matters rather than drowning in noise.
“ Managed Detection and Response extends that capability with round-the-clock expertise many organisations can’ t staff internally. But detection technology is only half the picture.
“ Ask how often your organisation actually runs tabletop incident response exercises, and whether those exercises include people beyond IT. Legal, communications, operations and executive leadership all have decisions to make during a live incident, and the time to discover who does what is well before an attacker forces the question.”
Factor five: Recovery planning should receive as much attention as prevention No organisation can assume it will never experience a ransomware attack. The most resilient organisations prepare for recovery long before an incident occurs by documenting recovery priorities, testing response plans and identifying the systems that must be restored first. A well-planned recovery strategy helps organisations resume critical services quickly while reducing financial and operational impact.	EXPERT REACTION	Frank Vukovits, Chief Security Scientist at Delinea, says:“ Resilient organisations treat recovery as a discipline in its own right, not an afterthought to prevention. The practical starting point is honest reflection: has recovery planning and testing genuinely been prioritised, and have resources outside of IT been dedicated to taking part? “ Recovery decisions – which services come back first, what‘ good enough to operate’ looks like, how customers are communicated	CONTINUES ON NEXT PAGE
