Four Must Have Security Applications


The internet has allowed us to send thousands of bytes of data and information in a matter of seconds. As much as the digital landscape has improved how we live and work, it also presents a new risk. Information transmitted or stored digitally can be subject to hacking from outside parties. With data breaches on the rise, it is important for organizations to have protocols and applications in place to protect their infrastructures. Luckily, securing your devices and network doesn’t require CIA-level training.

Here are four must have security applications for easily securing and protecting your network and devices.

Virtru E-mail Encryption

Not everyone is so lucky to have an Office 365 subscription which features integrated encryption options for Exchange Online. Luckily, a third-party email encryption application named Virtru is available for users of other email platforms. Developed by a former NSA agent, Virtru provides end-to-end encryption for emails and filed. Unlike traditional portal-based encryption solutions, emails are encrypted on your local device BEFORE they are sent, and stay encrypted until it reaches the recipients inbox. Data at rest is also encrypted in your mailbox, and users can set rules for the email to be revoked from the recipient at any time.

Virtru is available as a Firefox and Chrome plugin for Gmail, Yahoo! Mail, and as well as for Microsoft Outlook 2010 and 2013.


Two-factor authentication is nothing new, and definitely something we are very much used to by now. Every time we log in to our email accounts, we are using two-factor authentication by entering a username/email address and a password. DuoSecurity takes two-factor authentication to the next level. The platform provides authentication for just about anything including virtual private networks (VPN), remote access apps, password vault applications, Google Apps, and even UNIX. Custom security policies from DuoSecurity allow companies to set trusted devices and networks, and can even establish Geolocation parameters from where users can authenticate from.


LastPass is a secure password vault. Now why exactly do you need a password vault? Well contrary to popular belief, it is best practice to have a unique password EVERY SINGLE site and application you use. LastPass allows users to establish long-string, complex passwords for applications and websites and does the “remembering” of the passwords for you. With LastPass, all sensitive data is encrypted and decrypted locally before syncing which means that security keys never leave your device and the information is also never shared with LastPass – so your password information stays in your hands.


Okay, so we’ve talked about securing your emails and your passwords. But what about conducting secured phone calls? Signal is a service that provides additional privacy and protection by encrypting phone conversations as well as SMS (text) messages. Right now it is available for iPhone users and for Android in conjunction with applications TextSecure and RedPhone. Signal allows users to use their existing numbers and it doesn’t require a password. The only down-side is that in order for your communications to be secured, both parties need to have Signal installed, but luckily, the application displays which of your existing phone contacts are reachable via Signal.
