Email Encryption

Secure your communication with on-demand email encryption

Securely send, deliver, and manage critical data.

ExchangeDefender Encryption allows businesses to securely send, deliver, and manage confidential email. Whether your compliance officer provides a lexicon of words to trigger encryption, or your IT administrator configures sender/recipient policies for automatic encryption, or if you simply decide while sending the message that you want it encrypted – our encryption product will deliver messages securely to your recipients.

The system is entirely transparent with no software to install or manage on either end. Most importantly for everyone involved – it’s extremely user friendly.

Encryption Highlights

Pattern Matching

Pattern-based encryption that can detect credit card numbers, social security numbers, dates of birth etc.

Lexicon Keyword Matching

Lexicon dictionaries can contain words and word patterns that can trigger encryption mechanisms and protect from data leakage.

Corporate Encryption Mechanisms

Corporate encryption mechanisms can automatically encrypt messages or forward the contents to the administrator for the corporate review.

Comprehensive Reporting

Comprehensive reporting of all email activity as well as a Compliance Officer (CO) reporting with search capabilities provide proof of regulatory compliance and simplify reporting.

Cyber attacks are real, is your critical data protected?

Secure policy, lexicon and on-demand encryption that is transparent, automated and easy to use.

Flexible & Powerful Encryption Management

ExchangeDefender Encryption provides powerful control over email and even automates most of the encryption. Compliance Officers can provide lexicons, dictionary files containing words or phrases that can automatically encrypt emails that contain sensitive information. IT administrators can configure domain and email policies that automatically encrypt all messages between organizations, leaving nothing to chance. Users themselves have the ability to encrypt messages on demand if they know they are about to email sensitive content.

Additionally, ExchangeDefender Encryption is capable of performing pattern checks for most sensitive information that must be encrypted: account numbers, credit card numbers, social security numbers, date of birth, and unique identifiers can be used to scan each outbound message and automatically encrypted.

Transparent On-demand Encryption

Most compliance violations don’t get made by hackers – they are done when users send confidential emails. Why do many users knowingly send confidential data in plain emails? Because it’s easy and gets the job done.

ExchangeDefender pioneered transparent encryption: no software to install, nothing to manage and no training required. Simply add [ENCRYPT] or [CLEARENCRYPT] to the message subject and ExchangeDefender will take care of the rest. Best part is that this works on every mobile device, every webmail, and every email client.

User Friendly Interfaces

ExchangeDefender Encryption has a modern, powerful and flexible user interface that our clients love – in many ways it is better than many webmail systems. We focused on making our user interface look and feel like an email client in order to enable users to interact securely without having to go back and forth between email client and encryption web site. In combination with our Web File Sharing, ExchangeDefender Encryption allows our clients to attach very large files and truly collaborate in realtime with remote users securely.

For many users, ExchangeDefender Encryption user interface is the most valuable feature because recipients actually respond to it and use it. Competitive encryption systems are slow, sluggish and very unappealing in a sense that they simply make the recipient jump through multiple hoops just to retrieve the message – responding to a message securely is almost impossible. We heard this, and many other complaints, and have built a system that truly encourages collaboration and secure content exchange.

We had a prospective client about ready to pay separately for a web/file sharing solution. We were able to use the Web Share feature in ExchangeDefender as a selling point and a cost savings. Web Share definitely helped us close the deal.

Exchange Hosting and the simplicity of setting everything up has been great for the handful of clients that I have on it. Keep up the good work.

We've been on the hosted exchange for about a year, now. It's been nice to not worry about our own server's health, status, or management. Plus, switching devices and moving from computer to computer has been super easy. I don't think I would go back to running my own mail server.

With ExchangeDefender LiveArchive feature we were able to help our clients continue business as usual even though the power was out due to a winter storm. The ability to have each user access their email via the web using alternate Internet access allowed them to respond to email and support their customers without interruption.

I have been using ExchangeDefender for the past 3 years. During that time I have saved my customers about 60 hours of downtime, and blocked more than 100,000 spam messages. I have not had a single client stop using ExchangeDefender for any reason, their support and ease of use makes it a no brainer for me and my small business clients.

We have several clients depending on ExchangeDefender for their Exchange email and spam filtering services. The service is very reliable and comprehensive. ExchangeDefender is an excellent and cost-effective solution for small and mid-sized organizations looking to outsource their IT services.
