Email Encryption software is an essential tool that helps in providing secured real-time access to information from personal devices. It helps users protect messages or information written in emails from hackers. Email is a vital business tool used for the purpose of communicating confidential information among intended recipients; hence, Email Encryption solutions are needed to secure this information. Due to an increase in email usage for corporate as well as personal communication among individuals, sensitive information can be accessed by unidentified sources. This has encouraged users to adopt email encryption software to secure their data against thefts and losses. Email encryption works with the help of digital signatures known as public keys, such as Pretty Good Privacy (PGP) and GNU Privacy Guard. Users need to send these public keys to their contacts so that whenever they want to send any confidential information through an email, the email can be encrypted with the help of the public keys. Similarly, recipients also require a private key to decrypt information received in mails from other users. Email Encryption software can be implemented by users with the help of various devices, including smartphones, PCs, laptops, and tablets.

VISIONARY LEADERS

Visionary leaders are the leading market players in terms of new developments such as product launches, innovative technologies, and the adoption of growth strategies. These players have a broad product offering that caters to most of the regions globally. Visionary leaders primarily focus on acquiring the leading market position through their strong financial capabilities and their well-established brand equity.

DYNAMIC DIFFERENTIATORS

Dynamic Differentiators are established players with very strong business strategies. However, they have a weaker product portfolio compared to the visionary leaders. They generally focus only on a specific type of technology related to the product.

INNOVATORS

Innovators in the competitive leadership mapping are vendors that have demonstrated substantial product innovations as compared to their competitors under email encryption software space. The companies have focused on product portfolios. However, they do not have very strong growth strategies for their overall business, when compared with the visionary leaders.

EMERGING COMPANIES

Emerging companies have niche product and service offerings. Their business strategies are not as strong as that of the established vendors. The emerging vendors include the new entrants in the market, emerging in terms of product portfolio and geographic reach, and require time to gain significant traction in the market.

END-TO-END EMAIL ENCRYPTION

End-to-end email encryption is one of the secured ways of email communication. With the use of end-to-end email encryption, mails can be easily encrypted while sending from desktops. This kind of email encryption keeps mails encrypted until the time recipients open them with keys. It restricts third-party access while transferring messages from one user to another. It asks users to enter keys to open email information. Moreover, it delivers secure communication methods to users who demand the security of their information sent through emails. It is used for sending, receiving, and storing financial information, information related to stock markets, new policies, and other critical information.

GATEWAY EMAIL ENCRYPTION

Gateway email encryption is another way of encrypting emails, wherein emails are stored unencrypted within organizations and get encrypted only when sent outside organizations, or to third parties. It assists organizations in sending encrypted emails to their partners, clients, and users to reduce the risk of data theft and loss. Moreover, it enables recipients to open emails regardless of whether they are having their own email encryption solutions installed or not. This helps in securing data breaches while sending confidential data through emails to clients and partners. The gateway email encryption solution works with servers so as to manage encryption keys, policies, configurations, and the advancement of deployment. It encrypts data at the gateway and enables gateway emails to ensure data protection from unauthorized access while transmitting data through the internet. Many solution vendors provide gateway email encryption solutions, along with other encryption applications, to increase security levels.

BOUNDARY EMAIL ENCRYPTION

Boundary email encryption solutions are deployed with the help of hardware and software. They are installed at the boundary of an organization. Boundary email encryption provides secure information while sending and receiving messages. Moreover, this kind of email encryption provides policy-based configurations which permit systems to encrypt emails on behalf of senders and authenticate incoming emails for users. Furthermore, it enables easy deployment related to desktop-based solutions and provides policy-based security. However, it does not provide high- level privacy as it encrypts emails after they reach organizations’ boundary. This increases internal security breaches. The boundary email encryption solutions are incapable of verifying senders’ message and defining senders’ identification. In addition to this, they do not permit internal end-to-end encryption capabilities; for instance, if one department wants to send secure messages internally to another department within the organization, boundary email encryption is of no use.

HYBRID EMAIL ENCRYPTION

The hybrid email delivery model is also known as push mails delivery. In this model, messages are securely delivered to recipients as attachment files, along with decryption keys, so as to display messages in web browsers. These decryption keys are managed by senders, which are sent with the help of the authenticated SSL network. Hybrid email encryption provides solutions with the lowest common denominator to systems so that secured messages can be delivered to recipients. This model encourages users to use web-based mailing solutions so that ad hoc messaging can be done easily and securely.

CLIENT PLUGINS

Client plugins are the plugins that run over clients’ server, instead of dedicated servers. Moreover, plugins have access to clients’ interface, whereas dedicated servers do not provide access to clients’ interface. The client plugins help in providing access to virtual machines and other infrastructure tasks. They can be used to deploy Open Virtualization Format (OVF) and Open Video Ads (OVA) templates, and transfer files with browser data. Moreover, they can be used to connect virtual devices that exist in clients’ computer to virtual machines.
