What is Managed Detection and Response (MDR)?
As cyberattacks grow in volume and sophistication, even businesses with the strongest defences are at risk of being breached. Organisations need to not only try to prevent attacks, but they need to know how to respond. Managed Detection and Response (MDR) services help your business to be more responsive by combining advanced monitoring with proactive threat detection, investigation, and response.
What is Managed Detection and Response (MDR)?
MDR is a cybersecurity service that brings together technology and human expertise to deliver threat hunting, monitoring and response. MDR works by remotely monitoring, detecting, and responding to threats within your organisation. Typically, this is done using an endpoint detection and response (EDR) tool to gain visibility. Relevant intelligence is passed to human analysts who assess risk and determine the appropriate response. A combination of human and machine capabilities is then used to remove the threat and restore the affected endpoint to its previous state.
What Can MDR Do For Your Business?
As cloud adoption expands the attack surface and cyber criminals become increasingly sophisticated, it’s extremely challenging to find the necessary resources to protect your businesses. To be able to respond quickly to known and unknown advanced threats, you need complete visibility and coverage. Fortunately, MDR is able to offer some formidable business solutions:
- Automating Manual Processes - the more data you collect, the better coverage you have of your threat surface. The problem, however, is that the data needs to be analysed and contextualised. Human expertise is vital but, when done manually, it can take a huge amount of time and leave unidentified threats within your environment. MDR delivers automated detection and response capabilities to reduce the volume of manual work while ensuring attack signatures, indicators of compromise and malicious IPs are all accounted for.
- Reducing False Positives - due to the rapid evolution of the techniques, tactics and procedures used by cybercriminals, IT teams can receive an incredible volume of security alerts and false positives. Effective MDR solutions use Extended Detection and Response (XDR) platforms that leverage artificial intelligence and machine learning models to deliver high-fidelity detection and more accurate investigations.
- Augmenting Cybersecurity Resources - few organisations have access to their own security operations centre (SOC), despite its key role in building cybersecurity maturity. With MDR, you can outsource your SOC capabilities and gain access to a team of security experts and professionals who can help reduce risk without removing focus from your core business activities.
What Are the Benefits of MDR?
With MDR, your business can rapidly identify threats and reduce their impact without the need for additional staff. In fact, Managed Detection and Response services offer your business many benefits, including:
- Rapid and Robust Response - MDR can disrupt, isolate, and stop even the most advanced threats and ensure your business is never disrupted. With the right MDR provider, you can have confidence that cyber threats are being responded to on your behalf, even before you’re aware they're happening.
- Full Attack Surface Visibility - with MDR's multi-signal cyber threat intelligence, you can gain full threat visibility with a complete picture of the entire attack surface. The increased visibility enables deeper data correlation and threat investigation.
- Round-the-Clock Threat Hunting - instead of having to staff a team of threat hunters, you have access to a highly skilled team of security experts who rapidly investigate, contain and close down threats 24/7 when an automated response isn’t possible.
- Advanced Threat Detection - with MDR, you can gain access to world-class threat researchers who hunt the most advanced undetected threats and stay ahead of cybercriminals.
Questions to Ask a Potential MDR Provider
Not all MDR services are created equal, which means it's vital to fully vet any potential provider before working with them. Some providers can overload you with alerts, provide limited visibility and leave you to contain threats independently. What you want is an MDR provider that will not just alert you to threats but provide multi-signal visibility, threat containment and complete response capabilities on your behalf. While every MDR provider will claim to offer an effective solution, it’s not always evident if they go beyond offering alerts. To help you ensure you find an effective provider that can deliver robust protection for your organisation, it’s vital to ask questions such as:
- How will they identify risk, improve resiliency and optimise MDR?
- How will they alleviate complexity and resource constraints?
- How will they integrate with existing and future environments?
- How will they minimise dwell time and support incident response?
- How will they detect and automatically block the latest security threats?
Whilst these questions don’t cover every component required for an effective MDR vendor, they are a good starting point for finding a vendor to meet your specific requirements.

Mimecast recently released its State of Email Security Report for 2021. The fifth edition of its annual report used interviews with over twelve hundred of information technology and cybersecurity professionals across the globe to gather vital cybersecurity insights. The report offers an insight into the latest email threats along with advice on how to build cyber resilience and mitigate the risks of email-borne attacks.
Cyber attacks and data breaches have been commonplace in the news headlines for some time now. Although a warning from the media is certainly helpful, there is so much more that can be done when it comes to threat intelligence sharing. Threat intelligence sharing is an important part of the global cybersecurity community effort to tackle cybercrime and should form a part of every organisation’s cybersecurity strategy. Sharing cyber threat intelligence enables organisations to make informed decisions about their cybersecurity, building more effective and robust cyber defences.
One of my favourite annual reports to read is the Verizon Data Breach Investigations Report. It’s packed full of insights about the threat landscape and security leaders, in my opinion, should read this report to get a pulse on what’s happening in cyber-scape.
After all, as cyber leaders, we are here to stop breaches – so the insights gained from real cyber incidents and breaches is gold in learning how to tighten up our defences.
All businesses, large and small, are under increasing pressure to demonstrate that they are managing the risk of cyberattacks. This means having the right processes and controls in place to identify risks and vulnerabilities, protect information, as well as detect, respond, and recover in the event of cybersecurity incidents. As such, many businesses are turning to certification authorities and security frameworks to demonstrate privacy and security best practice and achieve compliance with regulatory bodies. System and Organisation Controls (SOC 2) is one such compliance framework that can help organisations to create a structured approach to cybersecurity.
Frost & Sullivan has recently released its 2021 Frost Radar: Email Security report, where its findings provide a benchmarking framework to help businesses protect their email from cyber threats.
As we operate in an increasingly digital world, every business collect, store, and share more and more data. And, amongst that data is personal information. With the OAIC marking this year’s Privacy Awareness Week (PAW) from Monday 3 May to Sunday 9 May 2021, it’s time for us all to review how we protect our customers’ personal information.
