"A great beginning. Microsoft Seal is the next step in encryption based tech platforms."
4/5
What do you like best about Microsoft SEAL?

I found Microsoft Seal to be a powerful library that meets almost all data processing needs of any organization. The fact that it is built on a homomorphic encryption system, makes it a truly delightful experience to use. Since data can be directly processed while being encrypted, it gives our clients greater confidence over system security and confidentiality. Review collected by and hosted on G2.com.

What do you dislike about Microsoft SEAL?

Homomorphic encryption still needs to evolve. There remain many issues related to the load on the system, the resources being consumed while processing data etc. These issues need to be resolved to make Microsoft Seal better. Review collected by and hosted on G2.com.

"Breakthrough technology in data storage and processing"
4/5
What do you like best about Microsoft SEAL?

it helped to store and process sensitive data on Azure cloud service without exposing it to the cloud provider. While doing POC on handwritten tweets our main challenge was to keep the signatures of individuals safe. Seal comes as a perfect solution as it provides one additional security on top of the private cloud. we don't have to expose data even to cloud providers. Review collected by and hosted on G2.com.

What do you dislike about Microsoft SEAL?

Technology is still growing so it's slightly slow to use. It would have been good if it had the analytical ability on encrypted data so that we could have given a third party to analyze data without exposing them to real data. Review collected by and hosted on G2.com.

"Microsoft SEAL (Simple Encrypted Arithmetic Library)"
5/5
What do you like best about Microsoft SEAL?

The best part is, that it is a free & open-source platform. Also what I like best, is the Homomorphic encryption that can implement meaningful operations on encrypted data without first decrypting them. It differs from traditional encryption methods in which it allows computations and operations to be operated directly on encrypted data without exposing the secret key. Review collected by and hosted on G2.com.

What do you dislike about Microsoft SEAL?

There are many known problems with the Homomorphic encryption, where it is close to practicality but not fully practical as it is resource-intensive, it can easily overwhelm & create overhead on the resources. Review collected by and hosted on G2.com.

"Microsoft Seal review"
4.5/5
What do you like best about Microsoft SEAL?

Microsoft Seal is built on the principal of homomorphic encryption and as per my knowledge is open source. It provides an additional layer of security as it makes possible the computation on encrypted data in the cloud, so it can be very well termed as state of the art homomorphic encryption. Many research papers are available on the topic. Review collected by and hosted on G2.com.

What do you dislike about Microsoft SEAL?

There are cons and downsides to the homomorphic encryption concept; it can be expensive to compute on encrypted data, and sometimes it may become impractical as it may require a lot of computational overhead. Review collected by and hosted on G2.com.
