Confidential Statement Delivery via EMail

How can the confidentiality of bank statements be compromised?

Large Banks and international organizations communicate and share large volumes of sensitive information with customers on a daily basis. From financial statements to deal confirmations, these E-Mail messages often contain sensitive and confidential information requiring encrypted data protection. Organizations continue to face challenges in making their existing eMail infrastructure a fully protected E2E email environment to enhance Privacy and data security. Complex migration projects or making 3rd party service providers offer such services open floodgates of important PII information being compromised.

Is a privacy-preserving email system “nice to have” or something we should strive to implement?

Securing email communications at Military / Law enforcement Hospitals

Problem statement:

Major challenges with Defense force- Healthcare units are the compulsory need to protect the confidential deployment of medical advice/information and PHI (personal identification/health information). As a civilian unit within the forces, Defense Healthcare providers and associated private clinics constantly communicate directly with the various members of the defense forces and patients carrying sensitive information. PHI information sent using regular emails are risky and open to attacks. While it is important to get data into the hands of recipients rapidly, it is equally important to send them completely protected. Are they safe enough?

Why does this happen?

Email is the most abused platform by Hackers and various types of attacks, and they are getting more sophisticated. Defense and law enforcement department health communications are the target of international hackers, as they pertain to a lot of confidential personal information related to the health of the forces and their families. The prevailing best email encryption techniques have not stopped hackers from breaching emails in use.
As most of the Encrypted eMail platforms use Cloud storage, they are not entirely secure, as it requires keys exchanged with service providers to process the eMails thus opening the door.

How is Zunu an ideal solution?

Zunu can be very easily integrated with Gmail and Outlook. Users do not have to migrate to a new platform to securely send confidential emails. Zunu doesn’t store any data of its users including username, password, etc. The emails sent and received through Zunu are always encrypted during transit while being processed and during rest. The feature which differentiates Zunu from other PGP-based email services is that it provides users with Complete convenience in addition to robust privacy. Emails can be searched while they are encrypted and retrieved in no time.


Names, Addresses, and Phone numbers on invoices are usually public records. There’s not much hackers can do with the information, right?

Secure communication of invoices

Not Right. Identity cannot be stolen with just name and address. But names can be plugged-in public databases and other related information can be retrieved. A long digital trial of an individual can can be followed to get enough information to open a financial account, or to make purchases. Invoices can contain data to fill in the lacuna.
For example, After every purchase a user makes on an ecommerce site, they receive an invoice for it as an email. This invoice includes the PII of the user. It consists of the details of food items purchased, the mobile number, address, and mode of payment for the purchase. There are a plethora of perils in sending invoices with such crucial information as plain text emails. Firstly, As it is in plain text, the email service provider reads it, stores it, and may even share the data in these emails with 3rd parties. Secondly, the information in these invoices is crucial, for example, the details of purchased food items. Email service providers can share these details with various insurance agencies, and they know the quantity and frequency of the food we consume. Our insurers know what we eat.
Any e-commerce platform can use Zunu to send privacy-preserving invoices to customers. The information, which is enormous PII like what one eats, what one wears, and where one goes is invisible to every email service provider and any 3rd parties.
