Directora de artes Small-Business (50 or fewer emp.) 9/19/2018 "It's a really easy way to centrally manage your keys" 3.5/5 What do you like best about AWS Key Management Service (KMS)? The key rotation does not need to decrypt and re-encrypt the data that was encrypted by the key. Old keys are still available to decrypt the data and the newly encrypted data will use new keys. It has automatic key rotation that is essential for compliance purposes. It does not require configuration to start. Review collected by and hosted on G2.com. What do you dislike about AWS Key Management Service (KMS)? KMS gives an easy rotation but you do not have much control. AWS will rotate it for you according to your own schedule annually. You can not force it. In addition, if you import your own keys, you must manage this key rotation on your own, which overrides the nice rotation service provided by AWS and, you must decrypt and re-encrypt the data encrypted with those keys. So keep this in mind if you are thinking about using your own keys. Review collected by and hosted on G2.com. Recommendations to others considering AWS Key Management Service (KMS): If you are looking for a more robust solution that can store asymmetric keys or require a Hardware Security Module, KMS may not be for you. You will have to make your own decisions about whether KMS makes sense for your organization. Review collected by and hosted on G2.com. What problems is AWS Key Management Service (KMS) solving and how is that benefiting you? WS KMS is a really easy way to centrally manage my keys, it helps me protect the data I store.

Leaders in Innovation Fellow Public Policy Small-Business (50 or fewer emp.) 9/28/2018 "KMS - Simple, secure and powerful" 4/5 What do you like best about AWS Key Management Service (KMS)? The ability to securely store keys and use them for encrypting apps and storage is unarguably the best feature of the AWS KMS. Within the AWS ecosystem the integration and interoperability is remarkable. Review collected by and hosted on G2.com. What do you dislike about AWS Key Management Service (KMS)?

Easy way to store your key pairs for use on EC2, Lambda, and a large amount of other assorted AWS services for almost no charge. Keeping track of keys on premise is dangerous and risky, beacuse it gives another system that you need to protect in order for your infrastructure to remain safe. through KMS, you can store all the keys that you need in AWS itself and therefore extend your security blanket to your keys as well. Review collected by and hosted on G2.com. What do you dislike about AWS Key Management Service (KMS)? Not much. The UI and AWS console is not very intuitive and can be confusing at times. I would really like to see a redesign of the UI from AWS as it is needlessly complicated and incredibly slow for a select number of operations. Review collected by and hosted on G2.com. Recommendations to others considering AWS Key Management Service (KMS): Definitely switch to it if you want to have your teams manage their own keys and do it easily. If however you want to have them manage keys that are on your own premise, it is better to keep them out of KMS and just manage them yourselves to prevent another possible point of access by unauthorized users to your important keys. Review collected by and hosted on G2.com. What problems is AWS Key Management Service (KMS) solving and how is that benefiting you? Solving security problems. It is a lot easier to manage security when your keys are all contained under the AWS shared responsibility model with all your other infrastructure. it also means that teams are more willing to increase security because managing keys is so much easier and less of a hassle.

I love the fact that we keep all of our keys in one place, and they're easily reachable via most of our internasl systems on an encrypted level. Review collected by and hosted on G2.com. What do you dislike about AWS Key Management Service (KMS)? I dislike the pricing schema for it. Chargina on a per key model is simple, but illogical for larger companies to use. We have thousands of keys that we'd like to live inside of the system, but it's too expensive to justify. Review collected by and hosted on G2.com.
