SOC 2 Type II NIST FIPS 203/204 Zero Plaintext

Data Loss Prevention with Fully Homomorphic Encryption

Traditional DLP scans data after it is already exposed. H33 prevents data loss by ensuring sensitive data is never in plaintext in the first place. You cannot lose data that was never exposed.


DLP Is Broken

Traditional data loss prevention works by scanning data after it is already in plaintext. DLP tools inspect emails, file transfers, API payloads, and database queries — looking for patterns that match sensitive data like Social Security numbers, credit card numbers, and protected health information.

The fundamental problem: by the time DLP scans it, the data is already exposed. The sensitive information exists in cleartext in memory, in network buffers, in application logs, and in temporary files. DLP does not prevent exposure. It detects exposure after the fact and attempts to block exfiltration. If the scan misses a pattern — and industry false-negative rates range from 5% to 15% — the data leaves undetected.

DLP is detection, not prevention. It is a fire alarm, not a fireproof building. Every DLP deployment assumes that sensitive data will be decrypted and exposed during normal operations. The best it can do is catch some of that data before it exits the network perimeter. In a world of cloud APIs, remote AI inference, and third-party model hosting, the concept of a network perimeter is increasingly meaningless.


The DLP Latency Tax

DLP scanning adds 50 to 200 milliseconds per request. Every email, every API call, every file transfer is intercepted, inspected against pattern libraries, evaluated against policy rules, and either allowed or blocked. For batch processing or low-throughput systems, this overhead is tolerable.

For real-time AI systems processing thousands of requests per second, this overhead is unacceptable. Banks disable DLP on high-throughput fraud detection pipelines because the latency cost exceeds the security benefit. Healthcare organizations exempt real-time patient matching systems from DLP scanning because the delay impacts clinical outcomes. AI inference endpoints skip DLP entirely because adding 100ms to every prediction makes the service unusable.

This is a known industry compromise. Security teams accept the risk because the alternative — adding DLP to every data flow — would cripple the systems that generate business value. The result is a coverage gap. The highest-value, highest-volume data flows are the least protected by DLP. The systems processing the most sensitive data are the ones exempt from scanning.


A Different Approach: Prevent Exposure, Don't Detect It

H33 eliminates the need for DLP scanning by ensuring sensitive data is never in plaintext. If data is encrypted throughout processing via fully homomorphic encryption, there is nothing for DLP to scan — because there is nothing to leak.

This is not encryption at rest, which protects data on disk but requires decryption for use. This is not encryption in transit, which protects data on the wire but delivers plaintext to the endpoint. This is encryption during computation. The AI model, the database query engine, the analytics pipeline — all operate on ciphertext. The plaintext never exists on any server at any point during processing.

You cannot lose data that was never exposed. Data loss prevention becomes a property of the architecture, not a scanning layer bolted on after the fact. The attack surface that DLP protects against — plaintext data in memory, in logs, in cache — simply does not exist when processing happens on encrypted data.


How FHE Replaces DLP Scanning

The traditional flow creates exposure. The H33 flow eliminates it.

Traditional DLP Flow
1 Data arrives encrypted
2 Decrypted for processing
3 Plaintext in memory / logs / cache
4 AI model processes plaintext
5 DLP scans output (+50-200ms)
6 Re-encrypted for storage/transit
Plaintext exists at steps 2-5. DLP catches some leaks. Not all.
H33 FHE Flow
1 Data arrives encrypted
2 Processed while encrypted (FHE)
3 Only ciphertext in memory
4 AI model operates on ciphertext
5 Result returned encrypted
6 Only authorized party decrypts
No plaintext exists. No DLP needed. Nothing to leak.

Head-to-Head Comparison

Traditional DLP versus H33 FHE across six dimensions.

Dimension Traditional DLP H33 FHE
When it acts After exposure Before exposure (prevents it)
Latency overhead 50-200ms per request 0ms (no scanning needed)
False positives 15-30% industry average 0% (no pattern matching)
Blocks data loss No (detects, alerts) Yes (data never exposed)
Works on encrypted data No Yes (operates on ciphertext)
Post-quantum No Yes (NIST FIPS 203/204)

Use Cases

FHE-based data loss prevention across regulated industries.

Healthcare PHI

Protected health information is never exposed to AI systems. Patient records, diagnostic data, and biometric templates are processed while encrypted. HIPAA compliance becomes architectural. A breach of the processing server exposes zero PHI — only ciphertext indistinguishable from random noise.

Banking PCI DSS

Cardholder data remains encrypted throughout AI fraud detection, transaction scoring, and behavioral analytics. PANs, account numbers, and transaction amounts never exist in plaintext during computation. PCI DSS scope shrinks because H33 servers never process plaintext cardholder data.

Legal PRIVILEGE

Privileged documents are processed blind. AI-powered contract analysis, document review, and case prediction operate on encrypted text. Attorney-client privilege is maintained by mathematical guarantee — the AI model never sees the contents of the documents it analyzes.

AI Companies INFERENCE

Training data and inference inputs are encrypted end-to-end. Model providers cannot access customer data. Customers cannot extract model weights. Both parties are protected. Encrypted inference eliminates the trust requirement between model provider and data owner.


Performance: 1,300–5,200x Faster Than DLP Scanning

H33 processes each operation in 38.5 microseconds. Traditional DLP adds 50 to 200 milliseconds of scanning latency. H33 is 1,300 to 5,200 times faster — and it actually prevents data loss instead of just detecting it.

Stop Scanning for Leaks. Prevent Them.

FHE-encrypted processing eliminates plaintext exposure entirely. No scanning overhead. No false positives. No data to lose. Deploy in hours, not months.
