One of the most important choices to make when selecting a cloud provider is whether your vendor will encrypt your data before they send it to the cloud, or if they will upload your data raw, and have it encrypted there. Uploading raw data is often seen as faster and more convenient with at-rest encryption. Taken as a whole, at-rest encryption comes with many disadvantages, that for most companies, should disqualify it as a viable solution. But when it comes to security, all the advantages and disadvantages need to be thought through carefully to ensure that your cloud encryption is effective. With this in mind, let’s explore three reasons why you should always choose a vendor that encrypts data before it’s sent to the cloud.
1. Enhance data security
Encrypting your data before sending it to the cloud provides an essential and fundamental layer of security. This is particularly important for the companies mentioned above who store sensitive and proprietary data, such as business documents, financial information, or personal files.
Your cloud vendor will likely have some kind of security measures to protect your data, but unless they encrypt it before it ever enters the cloud, there’s no guarantee that your information will remain secure in the event of an endpoint breach. Uploading your data raw will leave you vulnerable.
The bottom line? Don’t sacrifice genuine security in the name of convenience: your cloud encryption solution shouldn’t upload your data raw.
2. Maximize efficiency
Encrypting your data before uploading it to the cloud can also lead to more efficient data transfers. After your data is encrypted, your vendor will then send only the smallest amount needed to the cloud, consuming less bandwidth.
For companies who are paying for data usage or consumption, encrypting your data can result in cost savings over time. By encrypting (and therefore compressing) your data before you send it to the cloud, you can stay within your plan’s limits and/or avoid unexpected charges.
3. Reduce human error
As we said above, human error is the main cause of cloud data breaches — this means any solution your company chooses should have protocols to minimize that error. In general, manual data protection policies are known to be flimsy — a recent study from TAG Cyber summed it up: “Administrative control using manual procedures is inferior to technical controls based on automation.”
Encrypting your data before sending it to the cloud provides protection from this inferiority — particularly when transmitting data over home or public networks. At your office, your admin and IT teams have complete control over your network. But once hybrid and work arrangements are in play, all bets are off. This lack of network control drastically multiplies the risks associated with human error.
By encrypting your data before you send it to the cloud, you ensure that it is secure no matter what network your employees are using.
“Lock your suitcase” through the process of data encryption
As businesses continue to lean heavier on cloud providers to manage their data, they need to develop a greater understanding of how their vendors are protecting that data. This comprises basic concepts, but also finer points, too. Encrypting your data before sending it to the cloud vs. after is just one important example of choices and questions that fully informed companies will have to be ready to make when evaluating vendors.
Through an ongoing process of education — combined with expertise from CISOs or other IT specialists, your company can begin to clearly differentiate between comprehensive backup solutions like CrashPlan that encrypt your data before uploading it to the cloud, and other, less satisfactory options.
