Medium-sized companies sit in an awkward spot when it comes to security. You have more devices, more users, and more data than a small office, which makes you a real target. But you usually don’t have a full security operations team watching alerts around the clock. That gap is exactly why managed endpoint detection and response (EDR) has become one of the most requested security services for growing businesses.
This guide explains what separates a strong managed EDR provider from an average one, what to ask before you sign, and how to judge whether a provider is the right fit for a company with 50 to 1,000 employees.
What Managed EDR Actually Includes
EDR software runs on every laptop, desktop, and server. It records process activity, file changes, network connections, and user behavior, then flags anything that looks like an attack. The software alone is not the service, though. Managed EDR adds people: analysts who review alerts, investigate suspicious activity, and take action when something is wrong.
A complete managed EDR service should cover:
- Deployment and tuning so the agent is on every endpoint and alerts are not drowning your team in noise.
- 24/7 monitoring by trained analysts, including nights, weekends, and holidays when most ransomware attacks start.
- Threat investigation that tells you what happened, how far it spread, and which systems were touched.
- Response actions such as isolating an infected device, killing malicious processes, and blocking bad files.
- Reporting you can share with leadership, auditors, and cyber insurance carriers.
How To Evaluate Managed EDR Providers
Response Time And Authority To Act
Ask how quickly the provider responds to a high-severity alert and, more importantly, whether they are allowed to act without waiting for your approval. A provider that can isolate a compromised laptop within minutes is far more valuable than one that sends an email and waits for someone to read it Monday morning.
Coverage Across Your Environment
Medium-sized companies rarely run a single operating system. Confirm the provider supports Windows, macOS, Linux servers, and cloud workloads. Ask how they handle remote employees and devices that rarely connect to the office network.
Integration With Your Other Security Tools
EDR works best when it is connected to the rest of your security stack. Look for providers that can feed endpoint data into a SIEM and log analysis platform and coordinate with your firewall, email security, and identity tools. Isolated tools create blind spots.
Human Expertise, Not Just Software
Many vendors sell EDR licenses and call it a managed service. Ask who is actually watching the alerts, where they are located, and what certifications they hold. Ask for an example of a recent incident they handled and how it was resolved.
Clear Pricing
Managed EDR is usually priced per endpoint per month. Make sure you know what is included in that price. Some providers charge extra for incident response hours, onboarding, or after-hours remediation. A predictable monthly cost is easier to budget and easier to defend to leadership.
Questions To Ask Before You Sign
- What happens in the first hour after a critical alert?
- Can you isolate devices and stop processes on our behalf?
- How do you reduce false positives so our team is not overwhelmed?
- What reports will we receive, and how often?
- Will your reporting satisfy our cyber insurance and compliance requirements?
- Who do we call, and how quickly will a real person answer?
Why Local Support Still Matters
National providers can monitor endpoints from anywhere, but when an incident affects your servers, your phones, or your network, it helps to have a partner who can be on site. A local provider understands the businesses in your region, can meet with your leadership team in person, and can coordinate recovery work across your full IT environment instead of just the endpoint agent.
For Michigan companies, CTS Companies delivers managed EDR services in Michigan backed by our security operations center. We have helped businesses solve technology problems since 1980, and we pair endpoint protection with backup, recovery, help desk, and network security so your response plan does not stop at detection.
Signs You Have Outgrown Basic Antivirus
- You have had a phishing incident or suspicious login and could not tell what happened afterward.
- Your cyber insurance renewal asked about EDR, MFA, and 24/7 monitoring.
- Your IT team spends more time chasing alerts than fixing problems.
- You handle customer, financial, or health data that requires stronger controls.
If any of these sound familiar, managed EDR is likely the next step. It gives a medium-sized company the visibility and response capability of a large security team without the cost of building one.
Next Steps
The best managed EDR provider is the one that responds quickly, explains clearly, and fits the way your business actually works. Start by listing your endpoints, your compliance requirements, and the hours your team is available, then compare providers against those needs.
