Secure Collaboration
Your organisation shares sensitive files with dozens of external parties. Most have less security than you do.
Modern project delivery is collaborative by nature. Sensitive documents go to legal firms, design consultancies, technology partners, subcontractors, and financial advisors as a matter of routine. The productivity value is real. So is the risk.
You cannot control the security posture of every party you collaborate with. You cannot guarantee they will not forward your files, copy them to personal drives, or retain them after their engagement ends. You cannot see what happens to your documents once they reach an external environment.
GuardWare PROTECT solves this without slowing collaboration down. Your authorised partners work with your files exactly as they always have. The encryption is invisible to them. It is absolute to anyone else.
The challenge
When sensitive files leave your environment, your control over them traditionally ends. PROTECT changes that.
Traditional data protection strategies rely on keeping sensitive data within the perimeter. But the perimeter no longer contains modern work. Files go back and forth between organisations dozens of times across a project. Each transfer is a potential exposure point. Each party is a risk factor.
The question is not whether to collaborate. It is whether what you share remains under your authority after you send it.
How GuardWare solves it
PROTECT applies persistent file encryption at the file level using AES-256 and RSA-2048. The encryption does not pause when the file is opened, does not disappear when it is forwarded, and does not end when it reaches an external party’s machine.
Every file you share retains a unique encryption key managed from your central console. You control who can open it, when, and from where. When the collaboration ends, you revoke the key. The files become unreadable immediately, everywhere they exist.
PROTECT also integrates with Microsoft Information Protection (MIP), extending your existing classification framework to external collaboration without requiring partners to adopt new tools.
The Outcome
- Sensitive files stay protected across every external party, device, and environment
- Instant remote revocation ends access to all shared files when engagements conclude
- Authorised partners experience no workflow disruption, protection is transparent to them
- Full audit trail of every file access across every external collaboration
- MIP integration extends your existing classification framework beyond your perimeter
- Eliminates the commercial risk of sensitive data retained by former partners
Common Questions
How do I protect files shared with external partners?
GuardWare PROTECT applies persistent file encryption at the file level. Files remain encrypted in storage, in transit, and during active use. Authorised partners work with files normally. Anyone without authorisation cannot open them. Access can be revoked instantly from a central console.
What is persistent file encryption?
Persistent file encryption is encryption that travels with the file regardless of where it is stored, how it is transmitted, or who is holding it. Unlike standard encryption that protects data at rest or in transit, persistent encryption remains active when the file is opened and in use. If someone steals the file, the encryption remains. Without the decryption keys, the file is unreadable.
How does remote key revocation work?
Remote key revocation destroys the encryption key associated with a specific file, rendering it cryptographically unreadable instantly. It requires no physical access to the device holding the file. An engagement ends, an authorisation changes, or a security incident occurs — the key is destroyed from your central console and the file becomes inaccessible everywhere it exists.
Can GuardWare PROTECT integrate with Microsoft Information Protection?
Yes. PROTECT integrates with MIP to extend your existing classification and labelling framework beyond your organisational perimeter. Files classified and labelled within MIP can be protected by PROTECT, ensuring consistent governance across internal and external environments.
Does PROTECT disrupt how partners work with shared files?
No. PROTECT uses format-preserving encryption that is transparent to authorised users. Partners work with files exactly as they always have using their standard applications. The protection is invisible to them and absolute to anyone without authorisation.
