Understand anti-ransomware layers before you buy one
Most product pages skip this. We start here — so you buy a capability, not a buzzword.
What is an anti-ransomware layer?
A module that watches for files being encrypted and protects the restore points attackers try to destroy first.
Antivirus alone and hope for backups vs an encryption-focused layer — the honest table
What consolidation actually replaces, dimension by dimension.
| Dimension | Antivirus alone, then hope for backups | Heimdal Ransomware Encryption Protection |
|---|---|---|
| When encryption starts | Noticed when users report odd file names | Four behavioural engines flag it as it runs |
| Restore points | Deleted by the attacker before encryption | Shadow copy tampering is blocked |
| Recovery tools | Disabled as part of the attack | Kept switched on and unaltered |
| Your current antivirus | Ripped out to get anti-ransomware | Kept; REP X is sold to run beside it |
| Who reads the alert | Whoever checks the console next | Your team, or Heimdal MXDR if bought |
| What it is NOT | — | File rollback, a Linux agent, or a backup |
The cheapest test is the free trial: put REP on a lab machine, run a benign encryption simulator, and check the shadow copies are still there.
The five pieces of the platform
Vendors love diagrams; buyers need to know what they’re actually operating. Here’s the whole platform, demystified.
Module
REP is a module of the Heimdal agent on Windows desktops, Windows Server and macOS 10.15 or later. Heimdal lists no Ubuntu support for it, so Linux servers sit outside its reach.
Engines
Heimdal describes four real-time engines that judge behaviour rather than match signatures, so a strain nobody has catalogued can still be flagged by what it does to files.
Shield
Attackers delete Volume Shadow Copies and disable recovery tools before encrypting. REP blocks that tampering, so Windows’ own restore points survive for you to use later.
Console
Alerts reach the hosted Heimdal Dashboard, whose tenant data sits in Europe, the US or the UK. Heimdal’s MXDR team can watch the module for you, as a separately priced service.
A module on the Heimdal agent — four behavioural engines and a shadow-copy guard, reporting to a hosted dashboard.
Six capabilities. Detect, protect, operate.
REP X adds an encryption-focused layer to Windows and Mac devices and keeps the restore points attackers try to wipe.
Four engines, real time
Four engines watch file activity as it happens and judge it on behaviour, with no signature list to wait for.
Names the encrypting process
Heimdal’s how-to video shows REP picking out the malicious encryption process, so you know which executable to chase.
Restore points left standing
Attempts to wipe or tamper with Volume Shadow Copies are blocked, keeping Windows’ own snapshots usable after an attack.
Recovery tools kept on
REP stops ransomware from switching off or altering the recovery tools a machine would need once the incident is over.
Sits beside your AV
Heimdal sells REP X to run next to any antivirus, or inside its own platform, so the engine you trust need not be replaced.
A SOC can take the alert
Heimdal’s MXDR service covers REP, and MXDR ADAPT lets you choose per module whether analysts act or only notify you.

Here’s what genuinely sets it apart — and exactly where it stops.
A ransomware layer you add, not a migration
Most anti-ransomware arrives inside a full endpoint suite, so getting it means replacing the antivirus you already run. Heimdal sells REP X as its own line item and says it works alongside any antivirus, which lets a team keep its current engine and add an encryption-focused layer on top.
Watches what encryption does, not what it is called
The four real-time engines are behavioural and signature-free in Heimdal’s description. A new strain does not need to be on a list first: the pattern of a process rewriting your files is the trigger, and Heimdal’s own video shows the module naming the process responsible.
Keeps the way back open
Ransomware operators routinely delete Volume Shadow Copies and disable recovery tooling before they encrypt. REP blocks that tampering, so the snapshots Windows already keeps are still there when you start recovery. It is a quiet control, and it removes a step attackers rely on.
Where it stops
Heimdal documents no rollback of encrypted files; you restore from shadow copies or backups. There is no Linux agent, no published price and no analyst evaluation of the module. Nothing is hosted in India, since tenants sit in Europe, the US or the UK, and the add-on claim needs proving beside your own antivirus.
The numbers behind the platform
What your Heimdal REP rollout looks like
Map the ransomware exposure
List the Windows and Mac machines holding shared or business files, note which antivirus each runs, and flag Linux hosts.
Check shadow copies exist
Confirm Volume Shadow Copies are actually enabled on the target machines; REP guards restore points, it cannot create old ones.
Pilot beside the current AV
Deploy REP to a small group next to your existing antivirus and watch a fortnight for conflicts, slowdowns or false alarms.
Run a safe encryption test
Use a benign ransomware simulator on a lab machine, confirm the process is flagged and the shadow copies are left intact.
Roll out and set the owner
Extend to the full fleet, write the restore runbook around shadow copies and backups, and decide who answers each alert.
The review scoreboard
Modelled on Gartner Peer Insights structure. *Counts and breakdowns are illustrative pending verified review collection.
Quick poll — what’s driving your evaluation?
Talk to an advisor“We kept our existing antivirus and added REP on the finance laptops first. No conflict showed up in a month of running both.”
“In our tabletop test the simulator tried to wipe shadow copies first. REP stopped that step, and the snapshots were still there.”
“Good on Windows and our Macs, but half our file servers run Ubuntu, so those still rely on backups and nothing else.”
“Ask about rollback before you buy. It protects the restore points; getting the files back is still your job, not the agent’s.”
Where everyone sits — the grids
Analyst firms bury this view behind paywalls, and G2 retired its Grid. So here’s TechBag’s synthesis of the anti-ransomware market — tap any vendor to see why it sits where it does.

Which approach fits you?
Honest fit signals — because the fastest way to lose your trust is to pretend one product wins every scenario.
Choose Heimdal REP if…
- ✓You want an anti-ransomware layer on Windows and Mac without ripping out the antivirus you already trust
- ✓Keeping shadow copies and recovery tools intact through an attack matters as much as spotting the encryption
- ✓You may later hand ransomware alerts to Heimdal’s MXDR team and want the module already in place
Compare alternatives if…
- ✓You need encrypted files restored by the agent — Sophos CryptoGuard and SentinelOne rollback do that
- ✓Linux servers are part of the ransomware risk — Sophos, SentinelOne and Xcitium document Linux agents
- ✓Console data must stay in India — Sophos and SentinelOne both document a Mumbai region
Do not expect…
- ✓Automatic rollback of files that were already encrypted
- ✓A published price, or a Linux agent for your file servers
- ✓An analyst placement — Heimdal has no Magic Quadrant spot
Heimdal Ransomware Encryption Protection is one of 47 endpoint protection products TechBag carries. The Endpoint Protection guide narrows them to a shortlist and shows the reasoning. →
What does ransomware clean-up cost you?
Drag the sliders (protected devices; IT-staff hour cost). Estimates model staff time spent on ransomware drills, rebuilding restore points and re-imaging suspect machines at an assumed 1.5 hours per device a year, with 70% of it avoided when encryption is caught and shadow copies survive. Both figures are assumptions. Illustrative.

The 8 questions to ask every vendor
Take this into your next vendor call — including ours.
How many devices are Windows, macOS and Linux? REP covers the first two only, so Linux needs another control.
Which engine stays in place, and has it been tested beside REP on a pilot group before the full rollout?
Are Volume Shadow Copies switched on, with enough space, on the machines you most need to restore?
With no agent rollback documented, where do encrypted files come back from: shadow copies, backups or both?
Who acts on a REP alert at 2 a.m.: your own team, a partner, or Heimdal MXDR on a separate contract?
Does your data policy allow a tenant hosted in Europe, the US or the UK, since no Indian hosting option exists?
Does the quote count every device, servers included, and does it keep REP apart from the antivirus line?
Will the trial include a safe encryption simulation, with the result written down before any purchase order?
