Managed Detection and Response

Cyber threats have not slowed down and are increasing in their complexity and sophistication. The integration and reliance on technology to enable growth is also increasing, which poses serious risks to organizations if they don’t have proper security measures.

What EY can do for you

As cybersecurity threats continue to increase, businesses must develop more sophisticated systems to detect those threats. Tools and technologies such as antivirus, firewalls and intrusion detection systems are rule-based and provide limited protection against threats that have not been seen before or those that exhibit irregular or unknown behaviour.

EY’s MDR is the next evolution in threat detection. Our team offers an iterative approach for monitoring security events and offers a proactive way to hunt, detect and mitigate advanced threats before they compromise sensitive data assets or impact business operations. With EY’s MDR enables you to have control of your digital assets, allowing you to keep doing what matters most, accelerating your business.

Your security partners

We offer a 24/7 threat monitoring, detection and response capability to rapidly detect security incidents and minimize their impact.


EY’S MDR service is supported by an advanced technology stack which includes a combination of host and network layer sensors that gather data relating to security and system logs in near real time.

Threat hunting is a key component of the overall MDR solution and allows us to stay one step ahead of attackers. With the proliferation of “unknown unknown” threats, the threat hunt aims to seek and anticipate attacks via hypothesis testing before they occur and stop them right in their tracks.


We use a combination of data enrichment, advanced analytics, threat intelligence and skilled cybersecurity capabilities for investigation, threat hunting and response to immediately contain and disrupt detected threats.


Once a threat is detected, we provide real-time, context-driven advisories that are tailored to your business with tactical recommendations that can be actioned immediately to mitigate/reduce the threat.

Our technology stack has been designed to integrate and leverage the capabilities of leading information security products. We leverage emerging technology such as big data to provide actionable intelligence specific to your needs.
