What Is Managed Detection and Response (MDR)?
In today’s rapidly evolving cyber threat landscape, organisations need more than just conventional security measures. Introducing Managed Detection and Response (MDR) – a transformative solution to cybersecurity.
Managed Detection and Response (MDR): An Overview
Managed Detection and Response (MDR) is a cybersecurity service that combines advanced technology with expert human analysis to identify, investigate, and respond to threats in real time. Unlike traditional security solutions that may only alert you to potential threats, MDR actively works to neutralise them, offering a comprehensive approach to threat management.
The Role of AI in MDR
AI algorithms process vast amounts of data at incredible speeds, identifying patterns and anomalies that human analysts might miss. This not only improves threat detection rates but also reduces the time it takes to respond to incidents.
By integrating AI with human expertise, MDR providers can deliver more accurate and efficient security solutions. AI-driven automation handles routine tasks, allowing human analysts to focus on complex threat analysis and strategic decision-making. This synergy between AI and human intelligence ensures a robust defence against evolving cyber threats.
Key Features of MDR:
- 24/7 Threat Monitoring: Continuous surveillance of your network to detect and address threats as they occur.
- Advanced Threat Detection: Utilises AI and machine learning to identify sophisticated threats that traditional methods might miss.
- Rapid Response: Immediate action to mitigate risks and neutralise threats.
- Expert Analysis: Access to a team of cybersecurity professionals who analyse threats and provide actionable insights.
Types of Threats MDR Effectively Addresses:
- Advanced Persistent Threats (APTs): MDR's proactive threat-hunting capabilities are well-suited to detect and respond to APTs, which can often evade traditional security measures.
- Zero-Day Exploits: MDR's use of advanced technology, such as AI and machine learning, allows for the rapid detection and response to zero-day exploits, offering a crucial defence against unknown vulnerabilities.
- Insider Threats: Continuous monitoring can effectively identify unusual activities within the network, making it an invaluable tool in protecting against insider threats.
- Ransomware and Malware: 24/7 monitoring and rapid response can significantly reduce the impact of ransomware and malware attacks by detecting and neutralising them before they can cause widespread damage.
- Phishing and Social Engineering: The combination of technology and human analysis can detect sophisticated phishing attempts and social engineering tactics, providing a critical layer of defence against these common attack vectors.
- Data Exfiltration: Detection and response to attempts to steal or leak sensitive data, helping to maintain data integrity and safeguarding against data breaches.

An introduction to cybersecurity for decision-makers
Cybersecurity is an industry, a field of academia, a buzz-word, a science, an art and a bogeyman. And whilst cybersecurity cannot be avoided within any organisation that relies upon computers and data: there needs to be a way by which senior decision-makers can be involved in, and make decisions on, cybersecurity matters.
Cybersecurity is a highly specialised subject. It is complex and requires significant of knowledge and experience that is different from normal IT-knowledge. Knowing jargon and buzzwords does not mean that someone is an expert so always check the credentials of your “trusted advisors”.
Despite its overuse as a term, cybersecurity is fundamentally about protecting computer systems and data.
There are rules
Most territories now have laws around Data Privacy and many industries have regulations around information security. These must always be complied with and, irrespective of whether they are useful, they are necessary to operate in specific sectors.
Whilst the regulatory requirements may originate from the best of intentions: it is likely that organisations will need to do additional things to have the right type of cybersecurity for their specific profile and operations.
Why does anyone need cybersecurity?
Questioning why cybersecurity is needed is a good starting-point as it helps anchor solutions and initiatives to the fundamental driver behind activity in this space.
- The more you rely on (take advantage of) IT, therefore
- The bigger an impact to the organisation if something goes wrong, therefore
- The more you need cybersecurity
Cybersecurity needs to be seen as an enabler to using IT. Without cybersecurity, reliance upon IT is an incredibly risky thing to do. In-fact, one of the oldest risk equations in InfoSec (Information Security) works as follows:
Threat[1] x Impact[2] x Opportunity (Vulnerability)[3] = RISK
In mathematics if anything is multiplied by zero then the answer is zero. If there were no Threats there would be no Risk. If there was no Impact there would be no Risk and if there was no Opportunity to compromise a system there would be no Risk.
There are formal methodologies to measure the level of risk to an organisation as a result of a computer security breach. Sometimes formal assessments are useful to help shine a light on the scale of the issue. But if you are not required to undertake them then, in most cases, there is little benefit in going down this route.
Cybersecurity is a cost and, like other costs, it should be managed. For many organisations this means that the goal is to spend as little as possible on cybersecurity whilst having a proportionate level of protection considering the risk. Getting that proportionality right can be a challenge. Cybersecurity is routinely both a victim to underspending, where there is a lack of appreciation of the subject, and a cause of overspending, where the expenditure has not been objective focussed and consequently failed to achieve a useful outcome.
There are three fundamentals that an organisation needs to do regarding cybersecurity:
- Prevent an incident from occurring[4] – not all incidents can be prevented
- Detect an incident that has occurred – anti-virus cannot detect all incidents
- Respond well to an incident that has occurred – a good response can negate the impact of an incident
There may be exceptions to the above; but in-general all cybersecurity expenditure should be aligned to at least one of those three. Therefore, mapping initiatives against them can be a useful activity. Combining this with an articulation of effectiveness (a metric is best) is useful as it helps focus the initiative on the right outcomes for the organisation. At the risk of repetition: remember that cybersecurity is highly specialised. It requires specialist tools in the hands of specialist practitioners. Whilst an organisation could build their own Security Operations Centre (SOC), the question of “why?” should be raised. A company could generate its own electricity: but why would it do so?
Cyber expenditure almost always consists of both:
- Anticipated expenditure – the cost of the tool, service or technology
- Additional impact – specialist and (or) additional people, extra-training, recruitment, facilities and a distraction from core business
The following matrix (with a made-up example) is provided to help characterise cybersecurity initiatives. It is intended to be completed quickly, on the back of a post-it note, to help rapidly focus attention on the nature of the investment and whether the benefit, costs and approach have been considered. It is not intended to replace a full-investment case.
Final notes
No matter how much is spent on cybersecurity, and no matter what you are told, no company or product can guarantee safety. All anyone can do is make it less likely that an organisation will be compromised or reduce the impact of compromise. The inverse, i.e. not spending any money on cybersecurity, does not guarantee that an organisation will suffer a security breach. Not every organisation gets hit and some organisations are lucky. However, a strategy requiring luck is not recommended.
Whilst cybersecurity should be on the agenda: it should not monopolise it. Cybersecurity should be frictionless and, ideally, left to the professionals who should take the pain of it away. If cybersecurity is routinely causing you pain it is worth asking whether it is being managed as well as it could be.
Footnotes
[1] “Threat” refers to the groups or persons who do the attacking: Hackers, Nation States, Hacktivists. The entities that undertake the attack.
[2] Impact is not just the confidentiality breach of information. Depending on the circumstances, availability or integrity compromises can be highly impactful.
“Impact” is the impact to your organisation if they succeed in stealing, destroying, changing or making your systems and data unavailable.
[3] “Opportunity (Vulnerability)” is a measure of how accessible the systems and data are to attackers. Very secure government systems are not directly connected to the Internet and this reduces the Opportunity of attack considerably.
[4] Attackers have access to all the same technology that the defenders have and despite the prevalence of firewalls and anti-virus (both of which are much needed by the way), they are still able to breach organisations security and gain access to systems and data. Prevention is better than cure, but it’s just not practical to rely solely on this element.
