Breach-proof data protection
What if a breach didn't matter?
With persistent encryption, it doesn't have to.
Every security strategy is built on the assumption that a breach is the worst-case outcome. Organisations invest in firewalls, endpoint protection, identity management, and detection tools to keep attackers out. And they should. But breaches still happen. Phishing succeeds. Credentials are compromised. Zero-days are exploited. Insiders take files on their way out the door.
When that happens, the question every CISO faces is not whether the data was taken. It is whether the data that was taken can be used.
GuardWare PROTECT answers that question with a simple architectural principle: every sensitive file is persistently encrypted, so data that leaves your environment is worthless to anyone who takes it. They do not have the keys. They never will.
The challenge
Traditional security assumes the perimeter will hold. In 2026, that assumption is no longer sufficient.
A breach is not a failure of effort. It is a statistical inevitability for any organisation operating at scale with connected systems, external partners, cloud platforms, and a workforce using AI tools. The question is not whether your perimeter will ever be penetrated. It is what happens to the data when it is.
Traditional encryption protects data at rest and in transit. The moment a file is opened by an authorised user and passed along, forwarded, copied, or exfiltrated, the encryption is gone. The file is now unprotected, sitting wherever it landed, readable by whoever reaches it.
Ransomware attackers exploit this directly. They exfiltrate your data before encrypting your systems, then threaten to publish it unless you pay. That second threat, the publication threat, is often more damaging than the operational disruption. Operational disruption can be recovered from. A public dump of customer records, financial data, or commercially sensitive IP is harder to walk back.
How GuardWare solves it
PROTECT applies persistent file encryption at the file level using AES-256 and RSA-2048 hybrid encryption. The encryption does not pause when the file is opened. It does not disappear when the file is forwarded. It does not end when the file reaches an attacker’s server, an insider’s personal drive, or a ransomware operator’s infrastructure.
Every protected file carries its own unique encryption key. The keys are yours. If a file is exfiltrated, it cannot be read without your keys. It cannot be weaponised in a ransomware demand. It cannot be published to cause reputational damage. In every practical sense, it is worthless to whoever took it.
And if you need to act after the fact, remote key revocation destroys access to any file instantly, from anywhere, with no physical interaction required.
The Outcome
- Stolen data cannot be read, ransomed, or published without your encryption keys
- Ransomware’s double extortion model collapses, exfiltrated files have no publication value
- Remote key revocation destroys access to any file immediately after a breach is detected
- Every file access is logged for investigation and regulatory reporting
- Insider theft is neutralised; files copied to personal drives cannot be opened without authorisation
- Supply chain breaches do not become your breach; files shared with third parties stay under your control
How it works
Encrypt
PROTECT applies persistent AES-256 and RSA-2048 encryption to every sensitive file at the file level. The encryption remains active in storage, in transit, and while the file is in active use.
Control
Every protected file has a unique encryption key managed from your central console. You control who can decrypt it, when, and from where. No cloud provider, no third party, and no attacker can decrypt without your keys.
Revoke
If a device is compromised, an employee leaves, or a supplier engagement ends, remote key destruction renders all associated files unreadable instantly, from anywhere, with no physical access required.
Evidence
Every file access is logged. Who opened it, when, from which device. Your security team has the documented evidence for investigation, regulatory response, and insurance claims without reconstructing a timeline under pressure.
The ransomware equation
Double extortion ransomware works because the attacker holds something you need. They encrypt your systems and threaten to publish the data they took unless you pay. The second threat depends entirely on the data being readable.
PROTECT removes that dependency. If every sensitive file in your environment is persistently encrypted with keys only you control, exfiltrated data cannot be read, cannot be published meaningfully, and cannot be used as leverage. The extortion model collapses, not because the attacker failed to get the files, but because the files are worthless to them without keys they will never have.
