Why you should consider MDR vs. Antivirus protection  

As data and information becomes an increasingly critical business asset with which organisations develop strategy and drive transformation, cybersecurity and the protection of that data is also just as critical. The problem is that cyber attacks are increasing in volume, variety and complexity and therefore simply relying on a first line of defence like Antivirus protection is no longer enough. 

With the necessity to fast-forward digital transformation strategies in response to the pandemic, organisations have dramatically increased the number of devices, networks and endpoints being used. This much larger potential attack surface has led to an increase in cybercrime, with 39% of UK businesses across sectors identifying cyber attacks, and of this number 31% experienced a breach at least once a week. The reality is that threats happen and they can happen at any time, so your organisation needs to be ready to respond to and remediate them immediately.  

MDR vs. Antivirus protection 

Antivirus software has traditionally been a great first line of defence for many against active threats. However, as cybercrime becomes more frequent and complex, antivirus protection can only do so much. Although useful, antivirus programs can only identify known viruses and only once they’ve already infiltrated your network. In 2022, as an organisation you should be looking to improve cybersecurity maturity with more proactive approaches and systems – like MDR. 

What is MDR? 

MDR, or Managed Detection and Response is a multi-faceted security solution that combines proactive security threat management with security and defence technology to monitor, respond to and mitigate the risks of cyber attacks. It usually looks like: 

  • A unified defence suite 
  • Security Information and Event Management (SIEM) technology
  • A Security Operations Centre (SOC) 

With this in mind, here’s four use cases that demonstrate why your organisation should consider MDR over Antivirus protection. 

4 reasons MDR is right for your organisation 


1. You have adopted hybrid working 

While national Covid-19 lockdowns forced working from home setups, many organisations are now choosing to lean into more hybrid approaches as employees have embraced working more flexibly across both home and work environments. Although hybrid working is an asset for many organisations, with positive impacts on employee wellbeing and productivity, it can pose additional security risks. Hybrid working usually means an increase in the number of devices and endpoints, subsequently exposing your networks to increased risk of attack. 

MDR can protect against the kind of common, indiscriminate attacks that target as many devices, services or users as possible through round-the-clock monitoring and management. It can prioritise alerts for attacks like phishing and ransomware to ensure that the most urgent incidents are handled to minimise risk across the board. If your organisation has adopted a hybrid working model, it is here to stay (84% of workers who had to work from home as a result of the coronavirus are planning to continue with a hybrid working setup in the future), and therefore it’s now or never to implement a MDR solution that will proactively manage and mitigate the additional associated risks.  

2. Your organisation has minimal cybersecurity resources

Perhaps one of the more significant benefits of MDR is that it is a managed service, meaning a team of expert analysts are on hand 24/7, 365 days a year to monitor your organisation’s assets and infrastructure. Internal IT teams can often be resource-constrained, either due to a lack of skills and experience, manpower or simply time. Therefore, a dedicated team with the expertise to rapidly react to and resolve more sophisticated cybersecurity threats is something that any organisation can benefit from. As part of your MDR, an experienced Security Operations Centre team will carry out: 

  • Potential threat analysis and detection 
  • Continuous monitoring and improvement of security posture 
  • Threat hunting and incident containment 
  • Development of use cases 
  • Remediation activities

This level of dedicated monitoring and analysis also ensures your organisation is not left vulnerable to undetected attacks as a result of offline IT teams. Cyber attacks don’t operate within the confines of a Monday to Friday, 9-5 schedule, so neither should your cybersecurity.  

3. You’re concerned about the potential costs of cybersecurity breaches 

Data as a business commodity continues to increase in value, and therefore threats from cyber attacks and security breaches can be seriously costly for your organisation. When a security breach happens you don’t just lose the data or information and the value associated with it. Even with breaches that are restored within 24 hours, you might be looking at significant loss of productivity and output within that time frame, and any potential downtime can be hugely costly.  

The costs of organisational impacts also need to be considered. In a 2022 government cybersecurity survey, a quarter of businesses that experienced a security breach needed new measures in place to protect against future attacks, and 22% added staff to deal with the breach and inform others. Then of course there is also reputational damage, and the associated costs of potentially losing significant partners, stakeholders and customers as a result.  

Investing in an MDR solution can provide incredible value, with capabilities that can automate and provide a rapid response during high volume periods of potential incidents. With fast threat mitigation, MDR can isolate assets and respond quickly to attacks before they become financially detrimental to your organisation. For sectors that deal with classified and highly sensitive information, MDR is strongly recommended as a solution to improve the maturity and efficacy of your cybersecurity infrastructure.  

4. Your current cybersecurity infrastructure can’t handle the complexity of new threats

With the growing complexity of the threat landscape, managing your organisation’s cybersecurity can become over-complicated. Simply layering new security tools on top of your existing stack can actually pose more challenges in identifying and responding to attacks. A significant security stack can cause a high volume of alerts and create noise that can be difficult for analysts and engineers to filter through and investigate. 

MDR in comparison offers protection against advanced and evolving threats through a best-in-class cybersecurity portfolio. SIEM use cases are updated with the latest threats, to help continually mature your security posture. These use cases are then aligned to the TTPs utilised by threat actors, and therefore are much more equipped to uncover advanced threats that may have remained undetected. Your MDR security team will also be highly experienced, with the latest training and accreditations for detecting and responding to the latest cyber threats and attacks.
