What is an MSSP vs MDR?

Despite global efforts to mitigate cyber threats, the frequency and sophistication of cyberattacks are increasing. Malicious hackers are finding vulnerabilities in the software and systems. Also, the shortage of cybersecurity skills and constrained resources has made 24/7 surveillance at the required level difficult and expensive. 

So, it’s no surprise that Managed Detection and Response (MDR) is gaining popularity in the current threat landscape. 

Several leading organizations are outsourcing security capabilities to a third-party cybersecurity provider, with managed security service providers (MSSP) and Managed Detection and Response providers (MDR) as their preferred managed service providers . While there is overlap between the two cybersecurity services, each has its own advantages and disadvantages.

What is an MSSP and what do they do?

In the 2022 Gartner® Market Guide for Managed Security Services, Gartner states that “Managed security services (MSSP) providers offer an array of security services that vary from provider to provider. This breadth of service offerings provides wide choice but increasingly overlaps with capabilities offered by other market segments.” MSSPs are typically best used for threat prevention given that they deliver continuous security monitoring and asset management. MSSPs also rely on the use of SOAR technologies to arm their SOC analysts with automation and orchestration.

An MSSP remotely monitors network security events and sends alerts if they notice any anomalies. It also protects your internal systems from potential cybersecurity incidents through services like managed firewalls, intrusion detection, and vulnerability scanning.

With an MSSP, you get the benefits of the latest monitoring technology without having to acquire, configure, and monitor it yourself. This allows you to focus your internal cybersecurity resources on cyber threats more likely to become legitimate security incidents.

MSSPs augment your internal security team's efforts by ensuring they detect cybersecurity incidents as they occur, reducing the impact and cost to your company. In many cases, this may even increase alert fatigue for your security team. Moreover, MSSPs rarely respond to and remediate a threat. They typically alert on a detected threat and leave the incident response and subsequent remediation to the customer. Traditional MSSPs don't investigate the anomaly to eliminate false positives, nor do they respond to security threats, expecting the organization (you) to take the required action instead.

What is MDR and what does it do?

Gartner describes MDR as “a service that provides customers with remotely delivered modern security operations center (SOC) capabilities allowing organizations to rapidly detect, analyze, investigate and actively respond through threat mitigation and containment” in the 2021 Gartner® Market Guide for Managed Detection and Response Services.

A strong MDR provider will ingest multiple signals to provide 24/7 threat detection, investigation, containment, and complete response to their customers. Additionally, they leverage machine learning and AI-powered XDR platforms to deliver rapid detection and automatically disrupt threats.

MDR providers have 24/7 Security Operations Center (SOC) Cyber Analysts and a team of Elite Threat Hunters to conduct in-depth investigations into potential cyber threats, going beyond the abilities of endpoint detection and response (EDR) solutions. This includes eliminating false positives, pinpointing real security threats, and developing incident responses in real-time. In addition, there are three ways to measure the breadth of response capabilities:

• Response speed: Your MDR provider should be able to instantly and continuously detect and block threats. Alongside advanced automated technology, they should also have professional IT analysts on guard round the clock to protect you when human intervention is necessary.

• Response coverage: From a response perspective, your MDR provider should have coverage across your complete attack surface. They should always be one step ahead by engaging 24/7 threat hunters, global SOC support, and multi-signal intelligence to protect you whenever a hacker strikes.

• Response expertise: Your MDR provider should send you security alerts and take real ownership of protecting your business. They should contain and remediate cyber threats as part of their response capabilities, ensuring your business continues to run smoothly.

MDR providers also perform proactive threat hunting to prevent future cyberattacks or remediate intrusions that are undetected by your existing security solutions. This kind of deep visibility and control across your entire attack surface makes MDR service providers more likely to identify and respond to potential cyber threats that aren’t typically detectable using perimeter-based defenses and protect employees working remotely.

What are the Pros and Cons of MDR?

MDR vs. MSSP vs SIEM

When it comes to choosing the right security solution for your organization, there are a variety of options available. Although the two most popular solutions are Managed Detection and Response (MDR) and a Managed Security Service Provider (MSSP), some organizations choose to implement a Security Information and Event Management (SIEM) tool for a more cost-effective solution. However, since a SIEM is a technology platform, not a managed security solution, it is limited in use.

What is a SIEM?

Security Information and Event Management (SIEM) is a security solution that provides organizations with real-time insights into their IT environment. SIEM solutions are designed to collect and analyze, cybersecurity incidents to quickly detect potential cyber threats and help organizations respond quickly and effectively. Additionally, SIEM tools offer a variety of features including log management, anomaly detection, and user behaviour analytics, that can help organizations identify threats and take swift action to mitigate potential cyberattacks.

Unfortunately, given that SIEM is not a managed solution that only collects data sources from log signals, in-house security teams may not be able to gain full telemetry required to conduct a thorough threat investigation. As a result, security analysts may miss key attacker movements across their IT environment, resulting in weak or slow threat response. That being said, many MSSPs and MDR providers may leverage SIEM technology.

Before you commit to anything, learn about the various security postures within MDR and MSSP. Discover how they work with a SIEM platform and if that can help lighten the load for your internal IT security team.

MSSP vs. MDR: What should you choose for your organization?

The dividing lines between the managed security providers aren’t as clear as MSSP vs. MDR. Some MDR providers offer preventative services, and some MSSPs offer incident response and analysis of anomalies to remove false positives. 

Before making a decision, you should understand the different security postures within MDR and MSSP—and how they work with a SIEM platform to shoulder a few responsibilities of your internal IT security team.

Here are some general guidelines to help you decide between the two.

An MSSP may be the right solution if you:

• Have broad general security needs that don’t need extensive security expertise
• Don't have adequate internal security monitoring systems and passing programs
• Require sufficient knowledge on how to use cybersecurity tools efficiently

An MDR provider may be the right solution if you:

• Need rapid, robust response capabilities with the ability to disrupt, isolate, and stop the most advanced threats so that your business is never disrupted. You’ll be able to trust your MDR provider to respond to cyber threats on your behalf — before your team even knows there was a threat in the first place.
• Require complete threat visibility and investigation so your security team can see the complete picture of your entire attack surface with multi-signal cyber threat intelligence that enables deeper data correlation and threat investigation capabilities.
• Lack highly-skilled in-house security resources and want to benefit from 24/7 proactive threat hunting and disruption. Instead, you can engage an MDR provider with a team of highly skilled security experts who will rapidly investigate, contain and shut down threats when an automated response isn’t possible.
• Want to leverage an XDR platform so your team can stay ahead of new and emerging threats with high fidelity threat detection and automated real-time cyber threat disruption powered by unique intelligence from across the MDR provider’s global customer base.
• Need curated, original threat intelligence with access to world-class threat researchers who hunt the most advanced undetected threats. These researchers will develop, and deliver, original research, curate new cyber threat intelligence, and build advanced detection models to ensure your organization stays ahead of cyberattackers.

How to choose the right MDR provider for the organization

At its core, a best-in-class managed detection and response provider should demonstrate efficiency and effectiveness in improving your organization’s security posture across the threat landscape. They should be a direct extension of your in-house IT team and integrate seamlessly with your existing technology stack.

Here are the general criteria to determine the right option for your organization:

Consider the Mean Time to Contain

Given that the most aggressive ransomware attacks can take less than 45 minutes to deploy, speed is of the essence when it comes to threat containment. Look for an MDR security provider willing to commit to a Mean Time to Contain malicious activity. In addition, you should understand the length of time it takes to limit a threat to a single host within your environment and ensure the provider can follow through with the commitment.

Size of customer base matters

Because a Managed Detection and Response provider’s customers serve as the source for the data set used to train the XDR platform’s ML models, it’s important to choose a well-established company. After all, the more clients the provider has, the richer their data set. The richer the data set, the more accurate the detections, the quicker the investigations and the faster the containment will be.

Look for a Managed Detection and Response Provider that Customers Trust

One of the primary benefits of leveraging MDR services is that the provider can take containment and remediation actions on your behalf. However, you’ll have to give them permission to do this, which may mean ceding control over business-critical systems and processes. A provider that’s well-versed in performing incident response and remediation activities on behalf of multiple other clients in your industry will have the contextual awareness and experience to earn your trust.

In addition, a Managed Detection and Response provider who does a great deal of end-to-end containment and remediation will be able to incorporate information on those activities into its XDR machine learning training data. This means that its models will be able to operate on the basis of information that’s much richer and more extensive — encompassing the whole of the incident lifecycle — than those belonging to companies that primarily perform monitoring only.

Don’t Underestimate the Value of Integrations with Best of Breed Technology Providers

You’ll save money if you don’t need to rip and replace everything in your existing security technology stack. Even more importantly, however, operating across multiple vendors’ tools and solutions can enable complete cyberattack surface visibility and actually improve detection accuracy.

With that said, deep integration with a few key security tools is more important than broad integration with every tool. It’s more important to obtain full endpoint detection and response (EDR) telemetry and response integration than to integrate with every security toolset in existence.
