The main difference between MSSP and MDR comes down to who does the heavy lifting when something goes wrong:

• MSSP watches your digital perimeter, sets up your security tools, and sends you an alert if it spots something suspicious. But it expects your internal team to fix the problem.
• MDR watches your systems around the clock, hunting for hidden threats. It steps in to fix and block the threat itself.

MSSPs are effective at handling compliance requirements, managing firewalls, AV policies, and routine vulnerability scans so companies can meet regulatory expectations.

Where they fall short for lean teams is response. Most MSSPs focus on monitoring and alerting; they validate suspicious activity and send you tickets, but your internal staff still has to scope the incident, decide on containment steps, and carry out remediation.

MDR is an end-to-end service designed to go beyond monitoring. It uses a 24/7 security operations center (SOC) to provide proactive threat hunting, behavioral detection, and human analyst investigation to spot threats. SOC professionals use advanced technologies like AI and machine learning to isolate compromised endpoints or disable hacked accounts. This means your own team doesn't have to deal with every alert.

Even so, not all companies that call themselves an MDR solution actually do the fixing. Some traditional security providers bundle an MSSP alert-forwarding service and call it MDR. When you evaluate MDR or Managed EDR, ask for hard numbers like mean time to respond (MTTR) and false positive rate. Huntress, for example, reports an average 8-minute MTTR and a false positive rate under 1%.

Here's a quick comparison of MDR versus MSSP to help you finalize your decision on what cybersecurity model works better for your business:

Security Information and Event Management (SIEM) centralizes logs and security events from across your environment, but on its own it doesn't stop threats—it gives you more data to analyze. You need a SOC or managed service on top to turn those logs into detections, investigations, and concrete response actions.

Both MDR and MSSP use SIEM for different reasons:

• An MSSP with a SIEM solution focuses heavily on the technology platform itself. It uses SIEM to collect log files, watch your network's perimeter, and run vulnerability scans.
• MDR services process SIEM data, but human analysts integrate that information into advanced tools to actively hunt for threats and instantly block them.

Nobody knows your lean team's needs better than your IT leader and your tech workers. Nevertheless, it's easy to get lost in the bells, whistles, and promises of the many cybersecurity solutions on the market.

A good security partner must:

• Handle the response: Lean IT teams don't have the resources to run an in-house SOC. The solution must fix and block threats instead of handing over a long list of alerts.
• Be fast: Cyber attacks can completely take over a network in just a few hours. The response time must be minutes, not hours. Get the MTTR written into your service level agreement (SLA).
• Be transparent on pricing: Containment and remediation should be standard parts of the service, and not incur surprise extra fees.

Huntress Managed EDR offers 24/7 endpoint protection and remediation without the massive cost of building your own security team. While a traditional MSSP may validate issues and send you alerts to work through, our AI-centric SOC handles the work from start to finish: hunting for threats, investigating and validating every alert, and taking action to evict attackers from your endpoints. Deployment is lightweight and quick. Most teams can get Huntress up and running in minutes with minimal user disruption.

Labels don't guarantee outcomes. Not everything called MDR actually fixes your problems. Make sure your provider does the heavy lifting instead of just handing your team more work.

If you want proactive security and real fixes, get started with Huntress.
