Ransomware protection for Managed Service Providers (MSPs) has become a top concern in recent years, as attacks have increased in frequency and severity. A recent report by Bleeping Computer highlights the importance of robust ransomware protection measures for MSPs, which can have far-reaching consequences if compromised.
The report emphasizes that backup alone is not enough to protect against ransomware, and that endpoint detection without a rehearsed recovery path is equally insufficient. In fact, the Acronis Cyberthreats Report identified 143 MSP, IT-service provider, and telecom ransomware victims in 2025, with phishing accounting for 52% of initial access cases and unpatched vulnerabilities for 27%.
To mitigate these risks, MSPs must adopt a comprehensive approach to ransomware protection that includes prevention, detection, response, and recovery. This involves implementing controls that can detect activity before encryption, provide 24/7 response, preserve isolated recovery points, recover cleanly, and operate consistently across tenants.
One way to achieve this is by using a combination of Endpoint Detection and Response (EDR), Extended Detection and Response (XDR), Managed Detection and Response (MDR), and immutable backup. EDR monitors endpoint activity and supports investigation, isolation, and remediation, while XDR connects endpoint signals with other attack surfaces to provide analysts with a unified view of the incident. MDR adds people and process, providing around-the-clock investigation and response capabilities.
Immutable backup, on the other hand, protects recovery points from alteration or deletion, but does not replace incident response. It is essential to verify that each control is in place separately, rather than relying on a single solution.
MSPs can use a 6-point checklist to evaluate their ransomware protection services. This checklist includes:
1. Reducing exposure by setting patch SLAs and implementing multi-factor authentication (MFA) for management portals and remote access.
2. Detecting activity before widespread encryption through controlled behavioral testing and actionable incident detection.
3. Providing 24/7 response capabilities, including monitoring, investigation, containment, and client notification after hours.
4. Preserving recovery points by using access-separated, immutable, and offline copies.
5. Recovering cleanly by selecting a known-good point, scanning it, restoring in isolation, rebuilding dependencies, and validating the application.
6. Operating consistently across tenants through standard policies without flattening client requirements.
By following this checklist, MSPs can ensure that their ransomware protection services are robust and effective, reducing the risk of data loss and business disruption. It is essential to demand evidence from the service provider for each control, including tenant, workload, storage configuration, and service tier.
In conclusion, ransomware protection for MSPs requires a comprehensive approach that includes prevention, detection, response, and recovery. By using a combination of EDR, XDR, MDR, and immutable backup, and by following the 6-point checklist, MSPs can ensure that their clients’ data is secure and protected against ransomware attacks.
As a practical takeaway for readers, it’s essential to remember that no single solution can protect against all types of ransomware threats. A multi-layered approach that includes robust prevention, detection, response, and recovery measures is the key to effective ransomware protection. By staying vigilant and proactive, MSPs can reduce the risk of data loss and business disruption, ensuring their clients’ peace of mind.
