Post-access data security

Attackers don't break in. They log in.

An AI agent. A trusted insider. A ransomware attack. A phished password. A compromised vendor. Once authenticated, the data is theirs for the taking.

PostAuth enforces how a file can be used, even after access has been granted. Authentication was the boundary. With PostAuth, the file is.

Human or AI. Access is granted. Protection remains.

01 · The newest way in
AI agents
An agent can be given far more access than it needs, and even a properly authorized one can be turned by a hidden instruction or use its access in ways no one intended. In every case, valid access becomes a leak.
- Read the file it was grantedAllowed
- Extract contents into a replyDenied by policy
- Share outside the organizationDenied by policy
With PostAuth, an unauthorized agent gets only an encrypted file, and an authorized one stays bound by the file's policies on copying, extracting, and sharing.

Attackers now steal your data before they encrypt it, so restoring from backup doesn't end the threat.
Stolen copies stay encrypted under your policy.

One convincing message is all it takes. The attacker logs in as your employee, and every control sees an employee.
The files follow their own rules. The stolen login isn't enough.

A departing employee. An over-permissioned account. Someone who took far more than they should have. They're authorized, so nothing looks wrong.
Use is set by the file's policy. Every access is recorded.

Valid login. Open file. The actor changes. The weakness doesn't.

Why the stack misses them

Every control worked.
The data still walked out.

It isn't that the controls failed. Each one answers a question about access, and all five threats above begin after that question has been answered.

01MFA / IAM
What it answers: Who can access?
What it leaves open: What happens to the file after access is granted?
02Zero Trust
What it answers: Should access be granted?
What it leaves open: What governs use after access?
03DLP
What it answers: Is sensitive data leaving a policy boundary?
What it leaves open: What protects the file when the activity looks normal?
04Encryption
What it answers: Can protected data be read without the required key?
What it leaves open: What governs the file once an authorized user unlocks it?
05EDR
What it answers: Is the endpoint behaving suspiciously?
What it leaves open: What protects the file when the endpoint and session look normal?
06Data-centric / DRM
What it answers: Can this protected file be opened and controlled?
What it leaves open: What protects the files outside that coverage of labels, applications, and deployment?

Six controls.
One gap.

MFA confirms the user, Zero Trust approves the request, DLP watches the boundary, encryption releases the key, and EDR clears the endpoint. Every check passes. Access and use are two different questions. Most of your stack answers the first. The controls that reach the second only work on what they can inspect, what's classified, and where applications cooperate. PostAuth protects the file itself, without making inspection, classification, or application support mandatory.

You can keep building, managing, and patching layers, and the gap remains. Start with the gap every breach shares.

Incident analysis

These aren't hypotheticals.
Here's what they looked like.

Same attack, two endings. Every control performed exactly as designed. Only the data layer changes the outcome.

The attack · AI

Hijacked AI agent tokens

Example incident: Salesloft Drift

Every control said yes

The agent's OAuth tokens were valid
Every query was authorized
Bulk exports looked like normal integration traffic

Ending 1 · Without PostAuth

0% unusable

Stolen agent tokens pull data from hundreds of customer environments.

A trusted AI integration held standing access, so stolen tokens inherited all of it.

Ending 2 · With PostAuth

100% unusable

The agent's access stops at each file's policy.

The token still works. What it can do with each file is decided by that file.

The attack · Ransomware

Corporate network compromise

Example incident: Nike

Every control said yes

Authentication controls worked
Systems encrypted data at rest
Activity resembled legitimate file access

Ending 1 · Without PostAuth

0% unusable

Design files walk out readable and resellable.

Encryption at rest dissolved on login, so the files were readable the moment the session opened.

Ending 2 · With PostAuth

100% unusable

Every exported design file leaves as ciphertext.

Protection travels with the file, so the same session yields artifacts no one outside policy can open.

The attack · Phishing

MFA fatigue

Example incident: Uber

Every control said yes

MFA was satisfied
Zero Trust trusted the session
Endpoint tools saw no malware

Ending 1 · Without PostAuth

0% unusable

Internal files are readable inside the trusted session.

A satisfied MFA prompt handed over a trusted session, and nothing below it questioned the file access.

Ending 2 · With PostAuth

100% unusable

Access is evaluated file by file, every time.

The session is trusted. The file is not. Authorization is re-checked at the moment of use.

The attack · Ransomware

Unauthorized system access

Example incident: Conduent

Every control said yes

Authentication and internal access controls functioned
Data was encrypted at rest in storage
Bulk document exports were not prevented

Ending 1 · Without PostAuth

0% unusable

Bulk exports leave with usable customer records.

Authorized sessions decrypted files automatically, so volume was the only signal available.

Ending 2 · With PostAuth

100% unusable

Bulk exports leave as unreadable datasets.

Volume stops mattering. A million encrypted records are worth what one is: nothing.

The attack · Insider

Insider threat

Example incident: Waymo

Every control said yes

Authentication succeeded
The employee had legitimate access
Files were readable and exportable once opened

Ending 1 · Without PostAuth

0% unusable

An employee copies IP to a personal device.

No malware, no exploit, no policy violation. Legitimate access was the whole attack.

Ending 2 · With PostAuth

100% unusable

The copy exists and cannot be opened.

Legitimate access still opens the file at work. It does not travel off the approved device.

The attack · Third-party

Zero-day exploitation

Example incident: MOVEit Transfer

Every control said yes

Perimeter security and IAM worked
Files were encrypted at rest on the server
Files decrypted during transfer

Ending 1 · Without PostAuth

0% unusable

Mass transfer of readable files from a trusted platform.

Protection stopped at the platform boundary, and the transfer was where the files became readable.

Ending 2 · With PostAuth

100% unusable

The platform is compromised. The data is not.

Protection is a property of the file, not of the system holding it.

A return you can calculate.

PostAuth goes after the biggest driver of that cost: readable data in the wrong hands. Run the math with your own numbers: how likely a breach is, and what exposure would cost you. Then weigh how much of that cost protecting your files would remove against what PostAuth costs.

One investment. Five threats covered.

AI agents
Ransomware
Phishing
Vendors
Insiders

AI agents, ransomware, phishing, vendors, and insiders all end the same way: an authenticated user holding a file. Protecting the file addresses that endpoint once, so a single investment works against all five instead of five separate answers to buy, deploy, and manage. It sits alongside your existing stack, so you're adding a layer, not starting a program.

Less to extort.

Files attackers can't read give them much less to threaten you with.

Safer sharing.

Send files to vendors, partners, and AI tools knowing your rules go with them.

Evidence you can show.

Persistent, file-level protection gives you something concrete to bring to your CMMC assessment, and to point to for HIPAA, GLBA, ISO, and NIST and in cyber insurance reviews.

How it works

How PostAuth
works.

01
Protect the file.
Persistent AES-256 encryption and policies you define, attached to the file itself. Protection doesn't wait for a label. Classification helps you decide where to focus first.
- HumanEdit
- AI agentRead, no extract
- ApplicationOpen
- VendorDenied
02
Authorize every request.
When a human, AI agent, application, or vendor asks to open the file, the file's policy decides whether they can, and how.
03
Govern use everywhere.
Access doesn't unlock the file for good. Its policies stay in force as it moves across environments, applications, and users.

The environment can change. The actor can change. The file remains governed.
