# What Is Ransomware Rollback, and What Does It Not Protect You From? > A reference on ransomware rollback: how endpoint agents undo encryption, the limits set by the operating system, the window and the disk quota, the attacks it cannot reverse, and which small businesses should treat it as a buying criterion. Endpoint Index research (Reference). Published 2026-09-25, updated 2026-09-30, data as of 2026-10-02. Source: https://endpointindex.com/research/what-is-ransomware-rollback/ ## Executive summary **Ransomware rollback is an endpoint security feature that restores the files ransomware encrypted, deleted or changed on one device to their state before the attack, using copies the agent kept locally; it is a fast undo for an attack the agent caught, not a backup.** It works only on devices running the agent, only for changes the agent recorded, and only within a limited window. ThreatDown's, for example, reaches back 7 days, on Windows only. As of 30 September 2026, 13 of the 17 products in this database include rollback. Rollback does nothing about data an attacker copied out before encrypting, and nothing for files the agent never saw. It matters most to Windows-heavy offices whose staff keep working files on their own machines and who cannot wait a day for a restore. ## How rollback works The agent has to spot the attack first. Everything after that depends on what it saved beforehand. Vendors use one of three methods, sometimes combined: 1. **Protected copies.** When a process starts changing many files quickly, the agent copies the originals into a cache that ordinary processes cannot touch. 2. **Operating-system snapshots.** On Windows, some products rely on Volume Shadow Copy snapshots and guard them, because ransomware routinely tries to delete them. 3. **Change journals.** The agent logs every change a process makes, so each one can be reversed once the process is judged malicious. ThreatDown's [EDR page](https://www.threatdown.com/products/endpoint-detection-and-response/) (checked 30 September 2026) shows the practical limits of the cache approach. Administrators set the timeframe, a disk quota and a file-size limit. A file larger than the limit, or changes beyond the quota, are not covered. ## What rollback does not protect you from | Threat | Does rollback help? | Why | |---|---|---| | Encryption the agent detected on a protected device | Yes | This is what rollback is for | | Data stolen before encryption (double extortion) | No | Rollback restores files; it cannot recall copies an attacker has already taken | | Files on a device without the agent | No | The agent kept no copies there | | An attack the agent missed | No | Nothing triggers the rollback, and the cache may not hold the originals | | Encryption older than the window | No | The saved copies have expired | | Large files over the size limit | Often no | Vendors cap what the cache holds | | Deleted or corrupted backups, failed disks, theft | No | Only a backup covers these | The data-theft row matters most. CISA's #StopRansomware guide describes attackers who exfiltrate victim data and threaten to release it, a tactic it calls "double extortion". Rollback gets the office working again; it does nothing for the breach notification you may then owe. ## The operating-system limit Rollback is often a Windows feature, because the mechanisms it relies on, such as Volume Shadow Copy, are Windows services. ThreatDown's product page records its rollback as Windows-only. Other vendors say less, and the capability table below records only whether rollback is included, not on which systems.

If a third of your staff work on Macs, a rollback tick on the table may protect two-thirds of the fleet. Ask the vendor, in writing, which operating systems its rollback covers. ## Rollback and backup are different tools | | Ransomware rollback | Backup | |---|---|---| | Speed | Minutes, per device | Hours to days, depending on size | | Scope | Files on one protected device, within the window | Everything you back up, as far back as you keep it | | Protects against | Encryption by a detected attack | Encryption, deletion, hardware failure, theft | | Depends on | The agent spotting the attack | Copies kept offline and tested | CISA's [#StopRansomware guide](https://www.cisa.gov/stopransomware/ransomware-guide) (September 2023 edition) tells organisations to keep "offline, encrypted backups of critical data" and to test them, because ransomware seeks out and deletes backups it can reach. Rollback does not change that advice. ## Which buyers should care about rollback - **Windows offices with local files and no on-site IT.** A laptop restored in minutes by the agent beats waiting for an IT provider to reimage it and restore from backup. Rollback belongs on your shortlist criteria. - **Businesses choosing managed response.** Rollback and analysts are two answers to the same problem. [Huntress Managed EDR](/products/huntress-managed-edr/) shows the trade: rollback is not offered, and it relies on its analysts to contain and remediate instead. [ThreatDown Elite](/products/threatdown-elite/) includes both. - **Teams whose files live in cloud storage.** If working files sit in a cloud service with its own version history, restoring a laptop is less urgent. Rollback still helps, but it should not decide the purchase. - **Mac-first businesses.** Treat rollback as unproven for you until the vendor confirms macOS support. Products that lack rollback include CrowdStrike Falcon Go, where it is not offered, and Avast Ultimate Business Security. So does Microsoft Defender for Business, which surprises Microsoft 365 offices: rollback is not offered, because Microsoft's list of remediation actions (quarantine a file, kill a process, stop a service and similar) has no step that restores encrypted files. For those offices, a tested backup is the whole recovery plan. ## Buyer mistakes with rollback - **Cancelling or neglecting backups** because the endpoint product "has rollback". - **Assuming rollback covers network shares or other machines.** Confirm scope with the vendor. - **Not checking the window and quota.** A default cache set too small fails on the day you need it. - **Reading a rollback tick as Mac coverage.** - **Forgetting data theft.** Rollback does not end an incident that involved exfiltration. ## Which products with rollback suit a small business?

These products include both EDR and rollback, ranked by SMB Fit Score. EDR matters here because it shows what happened before the rollback, which you need for insurers and any breach assessment. ## Frequently asked questions ### What is ransomware rollback? Ransomware rollback is a feature of some endpoint security products that restores files ransomware encrypted or changed on a device to their state before the attack. It uses copies, snapshots or change logs the agent kept before the attack was stopped. ### Does ransomware rollback replace backups? No. Rollback covers one protected device over a limited window and depends on the agent detecting the attack. Backups cover deletion, hardware failure, theft and attacks the endpoint product missed. CISA recommends offline, tested backups regardless of what else you run. ### Does ransomware rollback work on Mac? Often not. ThreatDown's rollback is Windows-only, and other vendors rarely publish which systems rollback covers. Confirm macOS support with the vendor before relying on it. ### Can rollback recover stolen data? No. Rollback restores files on the device. If an attacker copied data out before encrypting it, that copy is beyond the reach of any endpoint product. ## Methodology and caveats Whether a product includes rollback is taken from the vendor's product or pricing pages and recorded, with a check date, on its Endpoint Index page. The database records whether rollback is included, not the window, quota or operating systems, which few vendors publish. ThreatDown's window, quota and file-size settings were checked on its EDR page on 30 September 2026. Confirm the details for your environment with the vendor. ## Sources 1. ThreatDown.
