Prevent sending emails to the wrong person

30% of data breaches are preventable

Most CISOs know human email error causes 30 percent of data breaches. Even the most diligent employees make mistakes that cause information loss. Janusnet reduces information lost through email with fast, simple, easy-to-use data classification, prompting users to:

  • classify sensitive information before transmission
  • classify document and files so they are controlled
  • check recipients clearances
  • recipient limits for different classifications
  • move multiple recipients to the BCC field before sending.


Unstructured data is difficult to manage, secure, and control. Adding mandatory data classification when creating, editing, printing, or saving documents is an easy, fast, accurate, and cost-effective path to data loss prevention. Integrating Janusseal markings with our technology partner solutions gives you control over unstructured data.


Visible data classification labels instantly alert your teams and external recipients to information sensitivity. Easy-to-see markings help employees follow corporate policies and procedures for information handling, which improves your organization's overall security posture.

If your organization manages sensitive information, you'll also have confidentiality requirements that need enforcement. Janusnet solutions help identify sensitive data and who should have access rights to that information.

Example of CUI data classification in MS Word with Janusseal


Controlled Unclassified Information (CUI) is government-created or owned information that requires safeguarding or dissemination controls consistent with applicable laws, regulations, and government-wide policies. Loss of CUI is one of the biggest risks to US national security. Non-compliance introduces significant risk to US government contractors.

Discover why government agencies and the Defense Industrial Base trust Janusnet to meet CUI compliance requirements.
