Ransomware protection for MSPs should deliver six tested outcomes: reduce exposure, detect activity before encryption, provide 24/7 response, preserve isolated recovery points, recover cleanly and operate consistently across tenants. Backup alone is not enough, and neither is endpoint detection without a rehearsed recovery path.

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%.

The checklist below turns those failure modes into controls and evidence an MSP should require before calling a service complete.

A complete ransomware protection service connects prevention, detection, response and recovery. For each control, demand evidence from the exact tenant, workload, storage configuration and service tier being sold.

Important: Immutable, offline and air-gapped describe different controls. Verify each one separately.

EDR monitors endpoint activity and supports investigation, isolation and remediation. XDR connects endpoint signals with other attack surfaces so analysts see one incident instead of separate alerts. MDR adds people and process: a staffed service investigates and responds around the clock. Immutable backup protects recovery points from alteration or deletion; it neither detects data theft nor replaces incident response.

Use them together. In the Acronis model, EDR provides endpoint detection and response, XDR extends visibility to email, identity and Microsoft 365 applications, and Acronis MDR operates on EDR or XDR. Acronis Cyber Protect Cloud supplies the backup, management and multi-tenant operating layer. Immutability is one recovery control; it is not the same as an offline or air-gapped copy.

Recovery time is the total of detection, triage, containment, clean-point selection, restoration and validation. An MSP reduces RTO by shortening every stage – especially the handoffs between security, backup, identity, networking and the client.

• Declare the incident, assign one commander and open an out-of-band channel.
• Identify affected tenants, identities, workloads and likely initial access.
• Isolate compromised endpoints and block malicious sessions, tokens and remote access.
• Preserve evidence before wiping systems or rotating logs away.
• Close the entry point by patching, disabling access and rotating credentials.
• Choose the latest recovery point that predates compromise and passes validation.
• Restore identity and infrastructure dependencies before applications and user data.
• Scan, test, reconnect in stages and monitor for renewed attacker activity.

Acronis backup scanning and malware-free recovery capabilities can help validate candidate recovery points, while Acronis Disaster Recovery can coordinate recovery workflows where licensed. The incident team should still confirm that the selected point predates the compromise.

Automation should remove repeatable waits, but an incident commander should approve high-impact actions such as mass isolation, credential resets and failover. A rehearsed path preserves the option to recover without paying, although no tool can guarantee recovery in every attack.

After each drill, record achieved RPO/RTO and every delay, then revise the runbook from evidence rather than estimated restore speed.

No. Immutable backup can preserve recoverability, but it cannot retract data that attackers already stole or remove breach-notification duties. A ransomware protection service must therefore look for exfiltration and identity abuse before encryption begins.

Correlate endpoint, identity, email, Microsoft 365, DNS, proxy and egress telemetry. During response, isolate devices, revoke sessions and tokens, rotate credentials, block attacker destinations and preserve evidence for legal and notification decisions.

Acronis EDR provides endpoint context and response, while Acronis XDR adds telemetry and response across email, identity and Microsoft 365 applications; network egress evidence may still come from firewalls, SIEM or other client controls. Test those handoffs in advance.

Before buying or standardizing a platform, require a live demonstration of these seven items:

• Coverage for client workloads and tenant tiers.
• Prevention and detection before broad encryption begins.
• Named 24/7 response ownership, escalation paths and approval boundaries.
• Immutable-storage mode, retention behavior and privileged-access separation.
• Clean-point selection, malware scanning and isolated restoration.
• Measured RPO/RTO in a dependency-ordered recovery drill.
• Multi-tenant roles, reporting, audit evidence and RMM/PSA/API integrations.

An integrated option is Acronis Cyber Protect Cloud with Acronis MDR.

It brings together capabilities for the six operational jobs, subject to the selected MDR tier, licensing, deployment, storage architecture and the MSP’s incident-response responsibilities. Require a live incident-and-recovery test using the production configuration.

A complete ransomware protection service should demonstrate all six outcomes across the client workloads it is contracted to protect. Acronis Cyber Protect Cloud with Acronis MDR is an integrated example. The MSP should validate the production configuration and confirm whether the selected MDR tier includes the required remediation and recovery actions.

Include exposure reduction, EDR or XDR detection, 24/7 response, access-separated immutable recovery points, tested clean recovery and multi-tenant operations with client evidence.

Remove handoff delays. Preassign owners, map dependencies, validate clean points, automate safe steps and rehearse restores until achieved RPO/RTO matches the service commitment.

No. It protects recovery data from change or deletion but cannot undo exfiltration. Detection, identity controls, egress visibility, containment and notification processes are still required.

Ransomware resilience is the ability to contain attacks early, preserve a recovery path and prove critical services can return on schedule. Acronis Cyber Protect Cloud with Acronis MDR can bring detection, response, recovery and multitenant management into one MSP operating model.

The MSP should validate the selected tier, storage architecture, integrations and operational responsibilities against the six tests above.
