Best encryption software for business in 2020: BitLocker, FileVault, Guardium, and more

From on-premise to hybrid environments and the cloud, we have you covered.

When mass data collection and big data analysis exploded on the technology scene, security and encryption, unfortunately, took a back seat. 

In a world where data breaches are commonplace -- involving everything from device theft to vulnerability exploitation and open AWS buckets exposed to the world -- businesses both large and small must now educate themselves and employ encryption software to enhance the data they have become controllers of. 

Encryption can help protect information stored, received, and sent. Readable information is scrambled through the use of encryption keys, algorithms that can sort through this text and return it to a readable format. Today, the Advanced Encryption Standard (AES) using 128- and 256-bit key lengths, the successor to DES, is in common use worldwide. 

If strong encryption and security practices are not in place, businesses are not only opening themselves up to potential cyberattacks, but also the loss of corporate and customer information, fines for non-compliance with laws including HIPAA and GDPR, financial damage, and the loss of reputation. 

Below, we list our favorite encryption solutions, suitable for users, SMBs, and enterprise players.

Microsoft BitLocker

Free

win.jpg

Best suited for: Windows users who need onboard device encryption
 
Microsoft's BitLocker, available on business editions of the OS and server software, is the name given to a set of encryption tools providing either AES 128-bit or AES 256-bit device encryption.
 
The Redmond giant's solution is focused on the encryption of drives on a device out of the box and can also be used to protect removable drives through BitLocker To Go. Recovery keys can also be set to retrieve data should firmware issues or errors prevent IT administrators from accessing encrypted drives. 
 
A set of administration tools, including features such as enabling the encryption of full drives and other media, as well as domain or Microsoft account linking, are included. 
 
BitLocker's hardware specifications require an onboard Trusted Platform Module (TPM) chip and Modern Standby support, two elements generally supported on modern Windows PCs.  
 
BitLocker is built into the Windows operating system but only a limited set of tools are included with Home editions, the standard OS that many PCs consumers purchase. Instead, users must upgrade to Windows 10 Pro or Windows 10 Enterprise to take full advantage of Microsoft's encryption.

IBM Guardium

Subscription

Best suited for: Enterprise users who need flexible encryption across multiple environments

IBM Guardium is a data protection platform that pulls together a suite of security tools in an effort to streamline data management and reduce vendor product disparity. 
 
Encryption services are included for corporate data, alongside data discovery and classification, vulnerability scans, data activity monitoring, analytics, and compliance reports, among other features.
 
IBM Guardium for File and Database Encryption can be used to encrypt on-premise files and databases by leveraging the hardware encryption capabilities of host CPUs including Intel and AMD AES-NI, PowerPC 8 AES, and SPARC. 
 
Data can be encrypted on-the-go without taking business applications offline, levels of encryption can be enabled to match user access rights, and keys can be managed from a central platform.  
 
A useful accompaniment to IBM encryption is access policies that can be set to identify anomalous behavior such as mass copy and deletion of files and directories. Compliance reports can also be generated to adhere to legal requirements set by GDPR, CCPA, HIPAA, PCI-DSS, and SOX.
 
The solution requires a virtual data security module (DSM) virtual appliance deployed on a VMWare hypervisor. IBM says some clients achieve an ROI of up to 343%.
 
IBM Guardium is a subscription-based service provided on request and is most suitable for enterprise companies willing to invest in a one-stop-shop solution for data management and protection.

Apple FileVault

Free

Best suited for: Mac users who want on-device encryption.
 
Apple's FileVault is built-in to the macOS operating system. Apple first introduced FileVault in 2013, later upgrading to FileVault2 on macOS Lion and later versions. The onboard system can be enabled to encrypt all information stored on disk to prevent the theft of data by anyone without access or account credentials. iMac Pro and users of devices with Apple T2 chips will have their information encrypted automatically. 
 
Modern CPU power is leveraged to provide AES 128/256-bit encryption. Users can choose to leverage their iCloud account credentials or generate a recovery key to unlock disks if they forget their standard device password. 
 
However, businesses should not consider FileVault to be a full, robust solution for data security; rather, it is a useful addition for ensuring a basic level of encryption and protection.

What we look for in encryption software

ZDNet's recommendations are based on major themes: Strength, flexibility of use, and multi-device and OS support. 
 
While some users and SMBs may need no more than simple, standalone encryption offerings to protect content on PCs, today's encryption solutions in the enterprise space -- especially important for larger firms -- must also keep hybrid environments and remote working in mind. 
 
Made even more crucial at present due to COVID-19, there is a high demand for encryption solutions able to protect corporate, sensitive data that may be accessed remotely by workers and hosted either in the cloud or in company networks. Strong encryption is now necessary when files must be shared with others not only to maintain your privacy but also to ensure data does not end up in the wrong hands.
