You send the email.
You keep control of it.

PPAD encrypts Gmail content and attachments so you can track, update, and revoke access, even after the email has been forwarded, downloaded, or read.

The problem isn't sending sensitive emails. It's what happens afterward.

Every time you send a sensitive email, you're handing control to the recipient. They can forward it, download the attachments, save them to a personal account, or pass them along to someone who was never meant to see them. Gmail makes that effortless, and there's nothing you can do about it once it's gone.

PPAD changes that. Protection is attached to the email and its attachments, not just the link or the inbox. So wherever that email ends up, access rules stay in force.

What you can do with PPAD in Gmail

Everything you need to protect sensitive emails, without leaving Gmail.

Encrypt email body and attachments

Send encrypted emails directly from Gmail. Recipients get a secure viewing experience; your content is never exposed in plain text.

Verify recipient identity before access

Recipients authenticate with a one-time passcode before they can read protected content. Unauthorized users, even if forwarded the email, stay locked out.

Revoke access at any time

Changed your mind after sending? Instantly revoke access to any protected email or file, even after it has been opened.

Block forwarding and unauthorised sharing

Prevent recipients from forwarding, copying, or sharing your protected emails beyond the intended audience.

Apply watermarks and screenshot protection

Automatically add dynamic watermarks to viewed content and block screenshots to deter leaks and unauthorised distribution.

Track opens, views, and engagement

Know exactly when your email was opened, how long it was viewed, and from which device or location, all from your Gmail sidebar.

Three steps. No new tools. No changed workflows.

Everything happens inside Gmail. Your workflow stays exactly the same.

01

Compose your email as usual

Write the email. Add attachments. Everything works exactly as it does today in Gmail.

02

Turn on the protection toggle

Before you hit send, enable PPAD. Choose whether to protect just the email body, just the attachments, or everything. PPAD encrypts the content and converts attachments into .ppad files automatically

03

Send and stay in control

Once sent, track access in real time. Update permissions. Apply additional protections. Or revoke access whenever you need to. No chasing recipients, no second-guessing what happened.

You can revoke someone's Google account. But not the emails already in it.

When an employee leaves, they often have months of sensitive emails and attachments sitting in their inbox, and they can access all of it before you revoke their account. Some save attachments to personal email. Others forward whole threads before their last day.

PPAD keeps access tied to permission, not just the account. The moment you want to revoke access to something a departing employee has, you can. Even if they've already downloaded it.

How PPAD handles leakage risk

Secure for you. Simple for the people receiving it.

One of the reasons traditional DRM fails in practice is that it makes life hard for recipients. People stop using it because their contacts won't bother opening protected files.

PPAD is designed with recipients in mind. There's no desktop software to install. They verify their identity with a quick one-time passcode, then access protected content directly in their browser, including files that have been downloaded.

No desktop software required

Works in any modern browser

Mobile-friendly secure portal as fallback

One-time-install lightweight Chrome extension for Gmail users

Answers to our frequently asked questions

Do recipients need to install anything?

No. Recipients can open PPAD files directly in their browser without installing additional software.

Do recipients need a Gmail account to access protected content?

No. Recipients are not required to have a Gmail account or the PPAD Gmail Plugin to access protected content. Users of Outlook, Microsoft 365, and other corporate email platforms can securely access protected emails and attachments via the PPAD online portal after successful authentication.

Can I revoke access after download?

Yes. You can revoke access or set an expiration date at any time, even after the file has been downloaded.

Is a PPAD file secure?

Yes. PPAD uses encryption and digital rights enforcement to ensure files cannot be copied, forwarded, or modified outside the rules you configure.

Is it safe to install PPAD Viewer?

Yes. The PPAD Viewer runs directly in your browser and there is no risk of downloading malware or unknown programs. You are simply extending your browser’s ability to open .ppad files securely.

What do I do with a .ppad file?

To open a .ppad file, you will need the PPAD Viewer. For full instructions, see our help desk guide on opening PPAD files.
