Security professionals understand that cybersecurity threats are evolving faster than many providers can effectively respond. Yet, many security providers still offer vague response targets that focus on what has happened in the past, rather than what will be done when the next threat emerges.
Initial access, lateral movement, and privilege escalation can unfold in rapid succession, with attackers increasingly automating each stage, compressing timelines and increasing risk.
Managed endpoint detection and response (EDR) services were built to address this exact challenge, but in practice, they can fall short. Many solutions advertise how quickly they can respond and report on their past performance, but they stop short of guaranteeing response when it matters most. For years, the industry has relied on averages to answer how fast a provider will, or should, respond. This includes mean time to respond (MTTR), service level objective (SLO), time to contain, and other incomplete response reporting that typically describe performance after the fact but offer no assurance in the moment.
When a real incident occurs, averages and targets do not protect your customers. Response does, and managed service providers (MSPs) need guarantees that their providers will meet the demands of today’s threat landscape.
That is why ConnectWise is introducing the industry’s first 15-minute SLA for Managed EDR, backed by a security operations center (SOC) that responds in real-time and provides enforceable accountability. That’s 15 minutes for detection, analysis, triage, and, where appropriate, containment and remediation actions. Or, where required, pull a human into the loop with a case escalation.
MTTR is one of the most widely used metrics in cybersecurity. It measures the average time it takes to detect, investigate, and respond to a threat.
For example, ConnectWise Managed EDR™ maintains an MTTR of eight minutes. That reflects speed and operational efficiency at scale. However, it doesn’t tell the full story. Security professionals do not need to understand how quickly threats were handled in the past, they need to understand how quickly the next threat will be handled.
As MTTR is inherently backward-looking, it includes a high volume of events that are resolved in seconds and automatically closed. This artificially lowers the average and can create confusion about response times during a true-positive incident.
When you are in the middle of an active threat, the only thing that matters is how long it takes to respond in that moment. Not what happened on average last quarter.
MTTR is undoubtedly a useful operational metric, but it is not a commitment.
A service level objective (SLO) is a defined performance target. It sets expectations for how a service should perform under normal conditions, and for many services, it’s sufficient. However, that’s not the case for a managed EDR offering.
In many MDR or managed EDR offerings, that often looks like a stated response time objective, such as responding to threats within one hour.
The issue is that SLOs are not enforceable. They are designed as internal goals, not external guarantees. If a provider misses an SLO, there is typically no consequence and no remediation for the partner.
For MSPs, that gap becomes a real business risk. You are the one responsible for protecting your clients, but you are relying on a vendor that is not contractually bound to deliver.
SLOs describe intent. They do not reduce risk.
A service level agreement (SLA) takes everything an SLO represents and adds accountability.
An SLA defines a guaranteed level of service and includes consequences if that guarantee is not met. In the context of managed EDR, that means a defined response time that is contractually enforced.
This is where the shift happens.
An SLA transforms performance from something that is measured into something that is guaranteed. That distinction matters because it gives MSPs something they, in turn, can guarantee to their clients to convey trust and accountability.
When you have an SLA, you are no longer selling best effort security or a low MTTR. You are now delivering a service with defined outcomes and built-in accountability.
The market is changing because the stakes are higher. Time matters more now than ever before.
Clients are more informed, more risk aware, and less tolerant of uncertainty.
They are asking harder questions.
How fast will you respond? What happens if you do not? Can you guarantee it?
MTTR does not answer those questions, and SLO does not have accountability.
An SLA answers all three.
That is why SLA-driven managed EDR services are going to become the new standard. They align security performance with business expectations and give MSPs a stronger position when selling and delivering services.
ConnectWise is introducing the industry's first 15-minute SLA for Managed EDR response time, designed specifically for MSPs that need both speed and certainty with specific EDR vendors.
This is not a target. It is a guarantee. With high-quality incident reporting, it’s an asset you can show to your customers to demonstrate the work you are doing on their behalf.
Partners can expect a response within 15 minutes, backed by actionable service credits if that commitment is not met. That creates real accountability and real alignment between vendor performance and partner expectations.
At the same time, performance remains a priority.
ConnectWise delivers an MTTR of eight minutes, placing it among the fastest Managed EDR/MDR providers in the market. But the difference is that this performance is not just reported, it’s supported by an SLA that ensures consistency.
This combination of speed and accountability is what defines next-generation managed EDR.
This shift has direct implications for how MSPs position and sell security services.
With an SLA-backed managed EDR offering, you can move beyond vague promises and lead with guaranteed outcomes. That strengthens your credibility and builds trust with prospects and customers.
It also reduces operational and reputational risk. If response expectations are not met, there is a defined mechanism for accountability.
Most importantly, it creates differentiation.
Many managed EDR providers highlight strong MTTR metrics. Fewer are willing to stand behind their response time with a true SLA. That gap creates an opportunity for MSPs to stand out in a crowded market.
