What is email encryption?

Who needs email encryption?

If you’re in one of these industries, encryption is a necessity.

Financial institutions.
Whether you’re a local tax advisor or a global securities firm, your entire business revolves around sensitive financial data. If you want to attract or retain clients, you need encryption to assure them that your email is safe.
Healthcare providers.
More than just hospitals, this includes everyone from general practitioners to insurance companies. Personal health information is every bit as sensitive as financial data; encryption tells patients and clients they can trust you.
Attorneys, brokers and more.
If your business deals with confidential information of any kind – from lawsuits to loan applications -- email encryption shows clients that you value their privacy and are doing everything you can to protect them.
