Choose from a wide range of granular DRM controls to tightly administer document access and use.

Locklizard vs other security solutions

Other document security and PDF protection solutions claim to protect your documents with strong encryption and restrictions, but they are easy to bypass or remove.
Locklizard use secure viewers to enforce DRM controls, don’t use insecure technology like passwords or plugins, & ensure documents always remain under your control.

Why Locklizard PDF DRM over PDF Password Protection?

Passwords seem a quick and simple way of protecting PDF documents with encryption but provide poor security:

	Passwords can be shared or removed Once you have given a user a password - you have to do this to let them open a document - they can share it with others or simply remove it.
	Passwords can be cracked Passwords can be broken with password remover software. Strong passwords can help prevent hackers accessing your PDF files as readily, but you must distribute them securely and manage them.
	Permissions or restrictions can be easily removed PDF permissions (restrictions) can be removed however strong the password is or simply ignored by PDF Reader applications. Why you should not password protect PDF files to restrict PDF use.
	Zero control after distribution You have no control over documents once they have been decrypted. Users can easily remove restrictions and edit, copy and print content. You have no idea who is using your documents or what they are doing with them.

Why Locklizard document DRM security over secure data rooms?

Secure data rooms make you believe you can share documents securely online. However, your documents are only as secure as the weakest link - login credentials can be shared with other users so anyone can login and view your ‘secure’ documents. See why data room security is not adequate for secure document sharing.

	No login credentials for users to share Users never enter any credentials so they cannot share them. Decryption keys are transparently relayed to an encrypted client keystore locked to the user’s device.
	No uploading unprotected documents Unprotected documents don't leave your computer so they can never be compromised. Secure documents on your local computer and distribute them by web, email, usb, etc.
	No useless JavaScript or weak protection Our DRM controls are enforced by our Viewers. Browser based viewers are easy to manipulate with script injections, in-line script editing, and browser plugins which can easily remove the security controls. See Google Docs and Flip books as examples.
	Stop screen grabbing & printing to PDF Stop print screen and third party screen grabbing tools capturing your documents. Prevent printing of documents to PDF and other file formats.

Why Locklizard secure PDF Viewers over PDF plugins?

At first glance plugins seem an ideal solution, enabling users to view protected PDF documents in Adobe Reader. But they require Admin rights to install and are a security risk.

	Plugins can be overruled Plugins can easily conflict with one another causing them to either stop working, or worse, stop enforcing DRM controls.
	Plugins can put users systems at risk Some document security providers require users to turn off security in Adobe Reader for their plugins to work. This puts the application and the user's system at greater risk of malware attack.
	Plugins can easily break Plugins have to work across multiple versions of Adobe so it is little wonder that they stop working when Adobe Reader updates are rolled out or when other plugins are updated.
	Plugins are not secure even if certified Anyone can write a plug-in for Adobe Acrobat without obtaining certification. However, certified plugins are not guaranteed as fit for purpose or secure, and authors can forge signatures so plugins run in certified mode.

How Locklizard compares to our competitors

Locklizard has taken a different approach to document security by avoiding known security weaknesses and complex implementation. Our DRM software is simple to use and secure.

	Secure PDF viewers We use our own secure PDF Viewers – so we have full control over the environment and can enforce DRM controls.
	No insecure technology We don’t use passwords, plugins, JavaScript, or temporary files - document decryption is done in memory only.
	Simple and secure key management Key management is handled transparently by the licensing server and secure Viewer - there are no complex keys to generate, distribute, manage, or for users to share.
	Full control over unprotected files No uploading of unprotected documents to servers where they could be compromized – protect documents on your computer and distribute them just like any other file.
	Device & location locking to prevent sharing We lock documents to devices so they cannot be shared, and optionally to locations so you can control BYOD use.
	Control over Operating System functionality We prevent high quality screenshots being taken by screen grabbing software, and block printing to PDF files and other unprotected file formats.
	Modular DRM controls DRM controls are expansive and flexible – you protect just one file for all users and control access on a user basis – so for example, you can have the same file expire at different times for different users.
	Total offline document protection Offline documents contain the same level of security as online ones, and you can optionally distribute the Viewer and protected PDFs on USB stick for total offline use.
	Significant cost savings & flexible hosting We provide perpetual unlimited use licenses, saving you thosands over competitor offerings. You host on-premise (on your own servers) or use our AWS hosted systems to get up and running straight away.
