Every email preserved exactly as it was sent.
Regulators, courts, and auditors require proof that archived emails have not been altered. IP Four deploys immutable WORM storage with cryptographic integrity verification so you can prove the authenticity of any archived email, years after it was sent.
Storage that proves your emails have never been touched.
From WORM architecture to cryptographic hashing, every layer of our tamper-proof storage is designed to give you irrefutable proof of email integrity when it matters most.
WORM Storage Architecture
Write-once, read-many storage ensures archived emails cannot be modified, overwritten, or deleted once captured. Every message is sealed at the point of archiving with cryptographic integrity verification.
Tamper Detection and Alerting
Any attempt to access, modify, or delete archived emails triggers an immediate alert. Full audit trail of every access event is maintained and available for regulatory inspection.
Cryptographic Hash Verification
Each archived email is assigned a unique cryptographic hash at the point of capture. Hash verification confirms the email has not been altered since archiving, providing court-admissible evidence of integrity.
Dual-Site Redundant Storage
Archived emails replicated across two geographically separate UK data centres. No single point of failure. Archive remains accessible even if one data centre experiences an outage.
Chain of Custody Documentation
Complete chain of custody records for every archived email. Who accessed it, when, and what action was taken. Essential for legal proceedings and regulatory investigations.
Long-Term Retention Assurance
Storage architecture designed for retention periods of 7, 10, or 25 years depending on your regulatory requirements. Data migration handled automatically as storage technology evolves.
From assessment to immutable archive.
Storage Requirements Assessment
We review your regulatory obligations, litigation history, and existing storage infrastructure. Retention periods, access requirements, and integrity verification needs are mapped before any configuration begins.
WORM Architecture Design
Immutable storage architecture designed for your organisation. Dual-site replication, cryptographic hashing, and access controls configured to meet your specific compliance requirements.
Capture and Migration
Live email capture begins immediately. Historical email migrated into the tamper-proof archive with integrity verification applied to every message. Migration completeness confirmed before go-live.
Access Control Configuration
Role-based access controls configured so only authorised personnel can retrieve archived emails. Legal hold administrators, compliance officers, and IT administrators assigned appropriate permissions.
Integrity Testing
Hash verification tested across a sample of archived emails. Tamper detection alerts tested. Chain of custody documentation reviewed and confirmed accurate before handover.
Ongoing Compliance Monitoring
Monthly integrity reports confirming archive health. Annual retention policy reviews. UK-based support for legal hold requests and regulatory enquiries. Storage capacity planning included.
How we have helped UK businesses prove email integrity.
Financial Services Regulatory Audit
A Leeds investment firm faced an FCA investigation requiring proof that client communications had not been altered since the date of the original exchange. Their standard email system offered no integrity verification.
Tamper-proof archive with cryptographic hash verification deployed. FCA investigators confirmed email integrity through hash comparison. Investigation concluded without adverse findings.
Employment Tribunal Evidence Dispute
A Birmingham employer faced claims that email evidence submitted during an employment tribunal had been altered. The opposing party challenged the authenticity of key correspondence.
Cryptographic hash verification confirmed emails were identical to archived originals. Chain of custody documentation provided to tribunal. Authenticity challenge dismissed.
Healthcare Provider Data Retention Audit
A Manchester healthcare provider was audited by the ICO regarding patient communication retention. They needed to demonstrate that archived patient emails had not been accessed or modified by unauthorised personnel.
Full access audit trail provided to ICO. Zero unauthorised access events confirmed. Tamper-proof storage architecture documented. ICO audit passed with no enforcement action.
