Managed detection and response: stopping today’s advanced threats in their tracks

November 18, 2022
Read Time 3 mins

When it comes to cybersecurity, there is no silver bullet. Technology solutions on their own cannot hope to prevent every breach, and halting the most advanced and sophisticated attacks in their tracks requires threat hunting led by humans, investigation, and response.

This is where managed detection and response (MDR) services are proving so effective. With MDR, companies across the board benefit from a fully managed, 24/7 service delivered by experts who have trained in their field for years, and who specialise in detecting and responding to today’s complex security events that IT solutions on their own cannot prevent. And although threat hunting can be performed on-premise using endpoint detection and response (EDR) and extended detection and response (XDR) solutions, there are far many more benefits to using an MDR service to either augment your security team or as a completely outsourced service.

Sophos supports three main MDR response models, as each individual customer has different and unique requirements. Firstly, an MDR team that manages threat response from beginning to end on behalf of the customer. Next, the MDR team works alongside the in-house team, co-managing threat response. Finally, an MDR team that alerts the in-house team to any events and provides remediation and mitigation guidance to them.

An unbeatable level of expertise

The benefits of MDR are many. For one, employing an MDR provider over having in-house staff handling these matters, will take security operations programs to a new height, particularly when it comes to dealing with the scourge of ransomware and other advanced threats. After all, the best predictor of future behaviour is past behaviour, and who better than an MDR vendor will have experienced the volume and variety of attacks?

Certainly no one organisation has this level of expertise, which would be practically impossible to replicate on their own. MDR providers are also far more proficient when it comes to using threat-hunting tools, which helps them to respond more rapidly and accurately. Moreover, working as part of a large and expert team allows analysts to share knowledge, skills, and insights, further quickening response and developing a type of ‘community immunity’, where lessons learned in one incident, can be used to prevent another.

Focusing on important issues

Perhaps one of the most compelling benefits of MDR, is that it frees up human resources and capacity to focus on more important business initiatives. Threat hunting is an extremely onerous and arduous task, and the work is unpredictable, often taking far longer than expected, and preventing valuable human skills from focusing on strategic business initiatives. The vast majority of businesses who use MDR say they achieve tremendous IT efficiency gains from using such services, which in turn, allows them to support their company’s goals far more effectively.

Similarly, with bad actors polluting every country around the world, an attack can happen at any second. No one is ever 100% safe, and by giving businesses around-the-clock coverage, MDR providers bring total reassurance and peace of mind to their customers. For in-house security teams, this means they are able to switch off at night and sleep, knowing the organisation and its valuable data assets are in good hands because the MDR provider has assumed the responsibility. Business leaders can focus on other work, secure in the knowledge that their organisation is safe, with experts on hand 24/7 who are fully prepared to handle any situation that might arise.

Bringing expertise on board

Another excellent reason for using an MDR service is that because threat hunting and detection is such a specialised field, practitioners in this arena need to have a very specific and unique set of skills. This means recruiting these skills is highly difficult, not only because they are few, far between, and in high demand, but they are extremely expensive too. MDR services give you the expertise you need, at a price you can afford. In turn, this helps companies to make their cybersecurity budgets stretch a little further, and proves a cost-effective way to elevate security initiatives, without breaking the budget.

Cybersecurity as a service

This is why more than 12 000 companies use Sophos Managed Detection and Response, as the company’s elite team of threat hunters and incident response experts take targeted actions on the behalf of all their customers to detect and eliminate advanced threats. Sophos MDR is truly cybersecurity delivered as a service.

Sophos MDR provides incredibly fast assistance, identifying and neutralising any active threats against your company, by employing fuse machine learning (ML) technology and expert analysis for improved threat hunting and detection, deeper investigation of alerts, and targeted actions to eliminate more sophisticated and complex threats.

In addition, Sophos goes beyond traditional threat detection, by combining deterministic and ML models to spot any anomalous or suspicious behaviours and the tactics, techniques, and procedures (TTPs) used by even the most cunning and advanced threat actors.
