SECURITY & DATA PROTECTION
How Scality secures the data you store.
Protecting data that cannot be lost takes more than one safeguard. It comes down to three things working together: the architecture that stores the data, the engineering discipline that builds the software, and the standards the platform is held to. This page walks through all three, starting with the threats they exist to stop.
The architecture
CORE5
Five layers of defense, each holding when the one above it is bypassed.
THE SOFTWARE
How we build it
Inspectable, standards-based software, maintained for a decade-long support horizon.
THE STANDARDS
Standards & compliance
Built for the financial, data-protection, and sovereignty rules you operate under.
The threat model
What a storage platform has to survive.
Attackers rarely go after the disks directly. They compromise an identity, escalate their privileges, and turn the platform's own commands against it. A storage platform earns its place by holding data when the layers above it have already been breached.
Ransomware that reaches the backup
Modern ransomware finds the backup repository and encrypts or deletes it before triggering the primary attack, leaving nothing to recover from. It increasingly steals a copy first and extorts on exposure, not just on encryption.
Credential and privilege compromise
A phished password or a leaked access key gives an attacker a legitimate identity. From there they try to escalate to an admin role that can change retention, disable protections, or issue delete commands the platform will honor.
Insider and administrator risk
The most powerful account is the one an attacker most wants and the one a malicious insider already holds. A resilient design limits what any single privileged account can destroy, even when it acts as the system itself.
Misconfiguration and exposure
The most powerful account is the one an attacker most wants and the one a malicious insider already holds. A resilient design limits what any single privileged account can destroy, even when it acts as the system itself.
Residency and jurisdiction
Where data physically sits, and whose legal reach extends to it, is a security question as much as a legal one. Data that crosses a border it should not is a breach of a different kind.
What's coming next
AI is making attacks faster and phishing harder to spot, and "harvest now, decrypt later" turns data stolen today into a future problem. A storage platform has to be built for the threats ahead, not only the ones on record.
96%
of ransomware attacks now involve data exfiltration. Blocking deletion is no longer enough; a stolen copy has to be unreadable.
89%
of organizations had their backup repositories targeted by an attacker in the past year. The backup is a primary target, not a safety net.
THE ARCHITETURE
The first answer is an architecture: CORE5.
API
Immutability at the interface
Data can be locked the moment it is written, with S3 Object Lock enforcing retention at the API so a request to modify or delete it is refused.
WHAT IT PROTECTS
Data
Identity, access, and encryption
Fine-grained IAM and MFA govern who can reach what, while TLS in transit and AES-256 at rest keep data unreadable to anyone without the keys.
WHAT IT PROTECTS
Storage
Erasure coding and hardened metadata
Every object is fragmented across many drives, and the metadata that reassembles it sits on a separate, hardened path. Raw disks reveal fragments, not files.
WHAT IT PROTECTS
Geographic
Multi-site, air-gap, and residency
Data replicates across sites and clouds with site-specific IAM, and can be air-gapped or held inside a defined jurisdiction for the most sensitive workloads.
WHAT IT PROTECTS
Architecture
Inherently immutable write path
Beneath the API, the write path preserves stored data in its original form, so protection does not collapse even if an attacker gains the privileges to bypass API-level controls.

This is CORE5 in brief. The full five-layer walkthrough, with the attack sequence each layer defeats, lives on the CORE5 page.
How we build it
Security also follows from how the software is built.
The architecture only holds if the software behind it is trustworthy. Two of Scality's operating principles carry the most weight here: engineering discipline, and full transparency about how the platform works. A storage platform runs for a decade, so it has to be built and maintained like it.
Inspectable, standards-based software
Open standards and inspectable software rather than opaque firmware, so operators and auditors can understand what the platform does with their data. In sovereign and regulated settings, a black box is itself a risk.
Vulnerabilities handled through the lifecycle
Security issues are tracked, prioritized, and patched across supported releases, so a platform that runs for years is maintained against the threats of today, not the ones it shipped with.
A clear path to report an issue
Researchers and customers need a direct route to report a suspected vulnerability and get a response. Coordinated disclosure keeps a found weakness on a path to a fix rather than an exploit.
These are the certifications and validations that security and procurement teams weigh when they choose a storage platform. Each is confirmed by independent audit and changes over time.

what it protects
The promises we keep for the data you store.
Architecture, engineering, and standards are the means. Together they keep four things true for that data: it stays confidential, intact, available, and recoverable.
- Only the right people can read it
Access control decides who can reach data, and encryption keeps it unreadable to anyone else, in transit and at rest, including a copy that is stolen or leaves the system.
- It cannot be quietly changed
Immutability and erasure coding mean stored data cannot be altered or corrupted without detection, whether the cause is an attacker, a failing drive, or a mistake.
- It's there when you need it
Access control decides who can reach data, and encryption keeps it unreadable to anyone else, in transit and at rest, including a copy that is stolen or leaves the system.
- You can get a clean copy back
When an attack gets through everything else, an immutable, recoverable copy turns a breach into an inconvenience instead of a shutdown. This is what makes storage ransomware-resilient.
Practical guide
Data security best practices for object storage.
To close, a short and practical guide for teams responsible for protecting large data estates. These practices apply to any object storage platform, and Scality is built to support each of them.
Enforce least privilege and MFA
Give every identity the minimum access its role needs, and require multi-factor authentication for administrative actions. Review access rights regularly and revoke stale accounts. The smaller each credential's reach, the smaller the damage when one is compromised.
Encrypt in transit and at rest
Encrypt traffic to and from storage, and encrypt data on disk so a stolen drive or an exfiltrated copy is useless without the keys. Manage keys deliberately, and keep them separated from the data they protect.
Make backups immutable, and keep a copy out of reach
Apply retention locks so backups cannot be altered or deleted inside the retention window, even by an administrator. Keep at least one copy air-gapped or otherwise isolated, so ransomware that reaches production cannot reach your last line of recovery.
Test recovery, not just backup
A backup you have never restored is an assumption, not a safeguard. Rehearse recovery on a schedule, measure how long it actually takes, and confirm the restored data is complete and clean. Recovery time is the number that matters during an incident.
Separate duties and watch for anomalies
Split critical roles so no single account can both weaken protections and delete data. Watch for unusual access patterns and unexpected deletions or retention changes, and make sure someone is accountable for acting when an alert fires.
