Top Managed Detection & Response (MDR) Service Providers 2021

    Many businesses aren’t large enough to have a full IT security team. In fact, they may not have in-house IT administrators at all. However, cybersecurity doesn’t stop being important just because a company doesn’t have the budget to hire full-time security professionals, so many organizations turn to managed detection and response (MDR) service providers to handle their security threats.

    Choosing a managed detection and response service provider

    What are Managed Detection and Response (MDR) Service Providers?

    Managed detection and response (MDR) service providers are companies that monitor an organization’s network 24/7 to identify, investigate, and remediate threats. They’re often third-party businesses that contract with organizations to provide round-the-clock monitoring and protection. Focused on being proactive, MDR providers focus on hunting threats, rather than patching vulnerabilities.

    What Should Companies Look for When Choosing MDR Services?

    When choosing an MDR service provider, here are the things you should look for:

    24/7 threat hunting and response

    Unfortunately, cybersecurity threats don’t stick to a 9-to-5 schedule, and MDR teams can’t afford to either. Businesses need a service provider that offers 24/7 monitoring to keep them safe, no matter when an attacker strikes. Not only should an MDR provider offer 24/7 monitoring, but they should also be proactively threat hunting to find malware that could be hidden in the network.

    Managed security infrastructure

    Some security tools like security information and event management (SIEM) and some firewalls need security analysts to proactively manage them to provide the best results. An MDR service provider should request access to these tools or include their own, so they can proactively monitor them during off hours.

    Ability to speak to experienced experts

    The managed part of MDR is having experienced security analysts available for the internal team to talk to. It should be easy for businesses to get in contact with their MDR team to discuss potential breaches and ask for help when they’ve confirmed an attack. Many providers will offer regularly scheduled meetings to discuss breaches the company has faced and any new measures they should implement to improve their cybersecurity.

    Global threat intelligence

    There are thousands of known malware strains out there, but without the right threat intelligence, they might as well be unknown to businesses. Threat intelligence provides data on the malware’s signature, how it typically enters a network, and the type of data it targets. In order to adequately fortify vulnerabilities, MDR providers should offer threat intelligence and work with businesses to guard against potential threats.
