Acronis Cyber Protect Cloud 25.10: New Update

Every software update has a story to tell. It’s not just about numbers or technical patches, but about how a tool evolves to face new security challenges. Acronis Cyber Protect Cloud 25.10 embodies that very idea: improving what already works and adding features that truly make a difference.

This version not only strengthens protection against modern threats, but also makes life easier for IT teams. From more efficient management to stronger security, everything points toward one goal: keeping your systems safer, more agile, and ready for anything.

In this article, we’ll walk you through what’s new in version 25.10, why it’s worth updating, and how you can make the most of its enhancements.

Top Highlights of Acronis Cyber Protect Cloud 25.10

Full Compatibility with macOS 26 “Tahoe”

The new Acronis Cyber Protect Cloud version is ready to protect devices running macOS 26 Tahoe, offering full support for workloads in the Apple ecosystem.

Key benefits:

1. You can now use Acronis Backup, EDR, RMM, and the Files Sync & Share integration without worrying about compatibility.

2. Everything runs smoothly with the latest macOS version, keeping both security and performance up to date.

3. Available through both workload-based and gigabyte-based licenses, and for solution or service models.

Perfect for teams already migrating to macOS 26 who don’t want to lose coverage or key cyber protection features.

Advanced Agent Uninstallation Protection

This update enhances endpoint security with a highly requested feature: the system now automatically blocks any unauthorized attempt to uninstall the Acronis agent. It’s an extra layer of defense against ransomware attacks or internal tampering.

Key advantages:

1. Prevents unauthorized removal of security agents.

2. Ensures constant protection even if someone tries to disable the software.

3. Admins can define a “maintenance mode” (from 1 hour to 7 days) to allow planned uninstalls or updates.

4. Replaces the old agent password protection, simplifying management.

All Acronis licenses include this feature at no extra cost.

Personal Signature in PSA Email Notifications

A small but impactful enhancement: technicians can now add their personal signature to automated emails sent from the PSA system (tickets, invoices, or quotes). This brings a more human, personal touch to every customer interaction.

Why it’s useful:

1. Reinforces your service’s professional and consistent image.

2. Makes notifications feel more personal, moving away from the cold tone of automated systems.

3. Enhances the customer experience by clearly showing who is handling the ticket or invoice.

Use cases:

1. Signatures can be configured for automated emails triggered by ticket creation or updates, invoice issuance, or quote generation.

2. Signatures are empty by default, so they must be set up manually.

Available for users with Acronis PSA licenses.

Cloud Integrations: New SIEM Connector 2.0

With version 25.10, Acronis takes a major step toward the world of MSSPs (Managed Security Service Providers). More and more service providers aim to consolidate all security events into a single platform — that’s where the new SIEM Connector 2.0 comes in.

This connector enables Acronis data (alerts, events, activities, tasks, EDR and DLP info, and more) to be sent directly to your SIEM platform of choice. MSPs can now enjoy a comprehensive and centralized view of all client security data, without technical headaches.

Main benefits of the new SIEM Connector 2.0:

1. Guaranteed compliance: Each client (tenant) has its own individual SIEM connection, ensuring data separation and regulatory compliance.

2. Simplified integration: No need for an intermediate server or gateway — the Acronis agent acts as a direct writer to the SIEM.

3. More data types supported: You can now send event logs, custom alerts, EDR and DLP data, and URL filtering info.

4. Greater technical flexibility: Supports CEF and JSON formats for broader compatibility with different SIEM platforms.

5. Smart management: Automatically filters out inactive tenants, reducing noise and optimizing processing.

Recommended use cases:

1. Send Acronis protection and security data to your corporate or client SIEM.

2. Integrate logs with tools like Splunk, Microsoft Sentinel, or QRadar.

3. Unify cybersecurity monitoring for all clients from a single dashboard, with no complex configurations.

All Acronis Cyber Protect Cloud licenses include access to this integration, with no additional modules required.
