Law firms hold data that remains valuable after a breach: client files, privileged communications, transaction documents, investigation material and sensitive deal data. Attackers can exfiltrate it for extortion or misuse outside the firm's trusted environment.
PastWipe™ reduces the usable value of stolen or exfiltrated data outside approved conditions and records each control decision as evidence. Selected protected material can be refused when the identity, device, purpose or environment no longer satisfies policy, reducing the leverage created by a usable stolen copy.
Where law firms start
- Client and matter files: advice, correspondence, evidence and working papers
- Privileged material: legal analysis, investigation records and sensitive communications
- Deal and data-room documents: due diligence, transaction drafts and disclosure material
- Litigation and disclosure bundles: documents exchanged with courts, counsel, experts and other parties
- Business records: client onboarding, billing, identity and internal governance information
Example workflows (illustrative)
- Compromised deal room: transaction documents are usable only by named participants, on approved devices, for the declared matter and period. Requests outside those conditions are refused and recorded.
- External counsel or expert: privileged material shared for a defined engagement remains subject to purpose, identity and environment conditions after it leaves the firm's systems.
- Exfiltrated matter files: selected files copied during an incident do not become permanently trusted merely because access was valid when they were obtained. Later use is re-evaluated against current policy.
- Incident evidence: evidence records show which protected material was requested and what was permitted, denied or degraded, supporting investigation and client review.
Designed to support evidence for…
- incident investigation and response
- client reporting and matter governance
- data-protection and information-handling review
- third-party, supplier and professional-risk assessment
PastWipe does not make a firm compliant and does not determine legal privilege, admissibility or professional obligations. Regulatory evidence
Fits the existing firm stack
- Uses available identity and device signals from existing systems
- Works with client-controlled keys (see Deployment)
- Sends evidence records to existing monitoring (see Integrations)
Limits
Results depend on integration depth and workflow control. PastWipe cannot stop every photograph, screenshot or manual copy, and copies that have already become unrestricted plaintext may be outside enforcement. See full limitations

Evidence scope
PastWipe is intended to support assessment of post-breach data-control measures and related records. The availability and scope of any evidence output depend on the agreed implementation. Customers and their advisers must assess its accuracy, completeness and relevance for their legal, regulatory, insurance or audit purpose. No claim is made that a record is automatically admissible in court, sufficient for a regulator or insurer, or proof that every copy of information has become unusable.
