It does not scan files at rest.
Only the file being written, at the moment it is written. Not other files on the drive, not folder listings, not the contents of the volume.
Itzal Shield
A file does not need an AI tool to leave. Shield checks the copy to a USB stick, the save into a sync folder and the upload to a personal account, using the same detection and the same policy as Guard.
What you get
These routes do not pass a gateway, so a gateway log cannot tell you they happened. Shield is on the device, where they do.
01
The drive's vendor and product id, a count and the file types. If there were findings, also the types, the counts and the masked file name.
02
The file is read as it is being written and until the check finishes. Files already sitting on the drive are never touched.
03
Allow and record, warn the person, or block the copy. USB can block while the sync folder only warns.
Where it works
Each destination has its own switch and its own action, and each is off until an admin turns it on and gives a reason.
Sync folders
Dropbox, OneDrive and Google Drive, the folder that quietly copies a laptop to somebody's personal cloud.
Removable drives
USB sticks and external disks, checked as the file is written. Blocked if the check finishes in time; recorded either way.
Personal and cloud sites
Personal email, file sharing, cloud storage and social sites on Itzal's list, plus every other website as a single switch.
Frameworks
A finding is not just a kind of data, it is a kind of data under an obligation. Each framework carries its own thresholds and its own action, which is what lets one laptop block for HIPAA and only warn for Internal.
HIPAA
Health records
Patient names, record numbers and clinical detail, under the identifiers the rule lists.
PCI DSS
Card data
Card numbers validated by Luhn and BIN, so a test number next to the word example does not fire.
GDPR
EU personal data
Names, addresses, identifiers and the context that makes them a record rather than a mention.
CCPA
California residents
The same personal data, under the obligations that apply in California.
GLBA
Customer financials
Account and routing numbers, balances, and the material non-public information around them.
FERPA
Education records
Student records and anything that identifies a student inside them.
SOX
Financial reporting
Unreleased results, forecasts and the working papers behind them.
Internal
Your own rules
Your patterns and your own kinds of thing, in your words: project codename, claim handler, deal name.
Plans
Shield is included in the two platform editions and sold as an add-on on the Guard editions. It is the same agent either way, so adding it is a licence change rather than another rollout.
Guard Essentials Add-on
Available on its own, priced per device like the edition.
Guard Pro Add-on
Available on its own, priced per device like the edition.
Itzal Business Included
Uploads anywhere, USB and sync folders, in the edition.
Itzal Enterprise Included
As Itzal Business, with dedicated tenancy and longer retention.
What it catches
Three routes out of a laptop, none of which appear in a web gateway log.
Leaving a job
Someone copies a client folder onto a USB stick on their last Friday.
The copy is checked as it is written. You get the drive's id, the file types, the finding counts and a masked file name, and the option to have stopped it.
Working around a block
An employee emails a contract to their personal Gmail to read at home.
Personal email is a known site. The upload is checked before it goes, and what happens next is the framework's own action.
Not thinking about it at all
A finance file gets saved into a folder that happens to sync to a personal Dropbox.
Shield sees the write, not the sync. The check happens on the device at the moment the file lands in the folder.
When it finds something
Three settings, chosen per compliance framework rather than per person, so HIPAA can block on the same laptop where Internal only warns. Most companies spend the first couple of months on the first one.
Quietest
Nobody is interrupted. You get a picture of what is happening before you change anything about how people work.
In the middle
A banner before the send, saying what was spotted. They decide, and the decision is recorded.
Firmest
Held until the data is taken out. Only where you have decided it is worth it, so the rule does not push people somewhere worse.
Set it to watch for a month, then decide. That is how almost everyone starts.
Book a demo How the rollout worksWhat Shield does not do
Every product on this site has a boundary. Ours are worth knowing before you buy rather than after, and the console reports them the same way.
Only the file being written, at the moment it is written. Not other files on the drive, not folder listings, not the contents of the volume.
No software on the laptop can. Shield covers what goes through the machine, and a phone pointed at a monitor does not.
If the check cannot finish in time the copy goes through and is recorded. We would rather record it honestly than hang the machine.
Questions
Short answers. The longer versions are in the pages linked from each one.
No. Shield is the same agent Guard uses. If Guard is already on the laptop, turning Shield on is a licence change and a switch in the console.
No. Only the file being copied, as it is written. Other files on the drive, folder listings and the contents of the volume are never read.
The drive's vendor and product id, a count and the file types, and no file names. A copy with findings also carries the finding types, counts, a masked snippet and masked file names.
Yes, and the console makes you say so. Switching a destination on asks you to confirm staff were told and to give a reason; both go into the audit log with your name.
Yes. “Every other website” is a single switch covering anything that is neither an AI tool nor a known personal site. Sites served over plain http are not covered.
The rest of the family
If Guard is already on the laptop, Shield is a setting. Nothing new goes out to the fleet.
Guard
Checks what people type, paste and upload into ChatGPT, Claude, Gemini and seven other AI tools, in the browser and in the desktop apps, before it is sent.
Read about Guard
Checks Outlook and Gmail before the send: the message, the subject, the attachments and who it is going to, on the machine.

Lens
Finds where sensitive data already lives and which AI tools are already in use, so the first policy is built on your company rather than on a guess.
