Rollout: Egress Secure File Transfer

The Egress service uses SaaS to make securely sending files a snap.

How It Works
Once installed and logged in, we were prompted with the package-creation interface, which lets a user add files to a secure package and define who will have access to the secure package. This interface is similar to adding files to a Zip file.

Once files are defined, the user clicks the Create Package button and is asked what type of package to create. Users can select e-mail attachment, if a supported e-mail client is installed; a standalone encrypted file; CD/DVD with encrypted data; or a regular CD/DVD. The difference between an e-mail attachment and a standalone file is simply that Switch attaches the file to an e-mail for the user, which saves some time.

Once we selected the type of package to create, the necessary steps are performed, and we have our new access-controlled encrypted package. All packages use a unique Advanced Encryption Standard 256 key, and information about the package, and your account, is transmitted via Secure Sockets Layer between the Switch client and Switch servers.

At the other end of the trail, opening secure packages requires:
  • Installation of the Switch client or browser
  • The secure package file
  • A unique account per person
  • Internet access

Double click the package, enter your account information, and once authenticated, the files can be accessed inside the encrypted package. Once a secure package is opened, the access is logged on the Egress servers for review later.

This feature alone is valuable to an organization's compliance program because it tracks access to sensitive data no matter where or when it's accessed. Unfortunately, like other secure packaging and file encryption tools, once a package has been opened, there's no way to track where the files go or who accesses them.

What It Costs
A single-user version of Switch is free but doesn't let the user share packages with others and doesn't provide package access tracking. The free version might be a good choice for users who need to create secure packages for one-time usage or storage and have no other encryption system.

Our Take
EGRESS' SWITCH FOR
SECURE DATA EXCHANGE
Switch's unique software-as-a-service approach takes the pain out of secure exchanges by letting users control who can access files and tracking access.
Monthly or per-package fee may be steep for some companies, but it's more cost-effective than some other options.
Service must be secure from attackers, otherwise, your account and data could be at risk.
Switch is only available for Windows, so enterprise Mac and Linux users are out of luck.
Organizations that need to transfer files, track who has opened them, and ensure that access is controlled can opt for a more robust multiuser edition of Switch. Users can pay per secure package they create, or pay a monthly fee. The pay-as-you-go option starts at $9.99 for five credits. A one-user monthly subscription is $49.99. This decreases to $7.49 per user for two to four users and $6.49 per user for five to 100 users per month.

Companies will have to weigh Switch's monthly fee scheme against the one-time payment for options such as PGP or even the widely deployed WinZip, which isn't marketed as a security product but can achieve similar results. Both PGP and WinZip also use AES-256 for encryption, although neither tracks or restricts who can access the package if the user has the password or encryption keys.

Switch's biggest benefits are its ability to track who has accessed the secure package and to restrict access to a defined list of users. It also can remove access without redistributing the secure package. Because Switch focuses on a different problem than traditional security tools such as PGP, it definitely has a place as an added level of security in the toolsets of many IT departments.
