Ransomware-Resilient Backup — Your Last Line of Defence, Built to Hold
Prevention layers stop most attacks. But no defence is perfect. When ransomware gets through, your backup is the difference between a fast recovery and paying a ransom. Ours is air-gapped, immutable, and completely out of reach — so it works when you need it most.
Why Most Backups Fail in a Ransomware Attack
Ransomware groups know that backups are your recovery option — so they target them first. Before deploying their payload, attackers spend days inside your network locating, corrupting, or encrypting your backup infrastructure. Traditional on-premise or Windows-based backups are particularly vulnerable: they sit inside the same environment the attacker already controls.
A backup that can be reached by ransomware is not a backup. Ransomware-resilient backup means air-gapped, immutable, and stored completely outside your environment — so no attacker, however deep inside your network, can touch it.
Most organisations believe their backups work. Many discover otherwise during an incident — corrupted restore points, incomplete coverage, reinfection from a compromised backup. A backup strategy that has not been tested and verified is not a recovery plan. It is a risk.
What Our Backup Service Provides
✈️ Air-Gapped & Immutable
Backups are stored in the cloud, completely separate from your computing environment. Ransomware cannot reach, encrypt, or delete them — regardless of how deep inside your network an attacker has penetrated.
🤖 AI Anomaly Detection
Entropy-based machine learning monitors your backups for unusual spikes in file additions, deletions, modifications, or encryption — identifying ransomware activity early, before it reaches your backup data.
🏭 Clean Recovery — Golden Snapshot
Automatically builds a clean "golden snapshot" from multiple restore points — the latest clean file versions from before the attack. No manual triage, no guesswork, no risk of reintroducing the threat.
🔍 Malware Scanning on Restore
Every file is scanned during the restore process — blocking malicious content before it re-enters your environment. You recover clean data, not a reinstated infection.
💻 Full Coverage — No Infrastructure
Protects endpoints, servers, Microsoft 365, cloud workloads, and SaaS applications — all from a single 100% SaaS platform. No backup hardware, no agents to maintain, no infrastructure overhead.
Our backup service is delivered through Druva — a 100% SaaS, zero-infrastructure cloud backup platform recognised as a Leader and Outperformer in the 2025 GigaOm Radar Report for Cloud Data Protection. Druva provides world-class granular restore capabilities, AI-driven anomaly detection, and clean recovery automation — all managed, all cloud-native, with nothing to install or maintain on your side.
Frequently Asked Questions
What makes this different from our existing backup?
Most traditional backups are stored on-premise or in a Windows-based environment — inside the same network ransomware has already compromised. Druva stores backups in an air-gapped cloud environment completely outside your infrastructure. Ransomware cannot reach them. Additionally, AI anomaly detection monitors backup data for early signs of compromise, and malware scanning on restore ensures you recover clean files — not a reinfection.
What data does this cover?
Endpoints (Windows, Mac), servers, Microsoft 365 (Exchange, SharePoint, OneDrive, Teams), cloud workloads (AWS, Azure), and SaaS applications — all protected from a single platform. No separate tools, no coverage gaps, no hardware to manage.
How fast can we recover after a ransomware attack?
Druva's automated golden snapshot and granular restore capabilities enable fast, clean recovery — individual files in minutes, full environments within hours. The exact recovery time depends on the scope of the incident and the volume of data, but the process is automated and designed to minimise downtime. Your recovery plan should be tested before you need it — not discovered during an incident.
Does this help with NIS2 and DORA compliance?
Yes. NIS2 and DORA both require documented business continuity and data recovery capabilities. Druva provides the backup policies, retention documentation, and recovery logs that auditors require. The immutable, air-gapped architecture also directly addresses NIS2's requirement for resilience against ransomware — including documented evidence that backups cannot be compromised by the same attack that hit your primary environment.
