With passwordless access, recipients don’t have to remember or manage yet another password—instead, they can securely open messages from Cloudstar using their device’s built-in security like fingerprint, face recognition, or a trusted passkey. This makes the process fast and easy for users, while reducing the risk of weak or reused passwords. It’s especially helpful for busy professionals on the go or anyone who prefers technology that just works without the hassle of logins. For businesses, this approach not only improves user satisfaction but also strengthens security and supports modern compliance requirements.

Two-Factor Authentication (2FA)

Adding an extra layer of protection, two-factor authentication requires recipients to enter not just their password but also a one-time code sent to their phone or generated by an app. This helps ensure that only the intended recipient can open the encrypted email, making it much harder for unauthorized users to gain access. Cloudstar’s 2FA meets important security standards like PCI-DSS, giving businesses peace of mind that sensitive data stays protected while still being convenient for users.

Sender Set Passphrase

Think of this like sharing a secret word with a friend so they can unlock a message you sent them. With Cloudstar’s sender set passphrase, the person sending the email creates a password and shares it with the recipient separately—this way, the recipient doesn’t need to register or sign up for anything. It’s a quick and simple way to securely share sensitive information while keeping control over who can see it. This approach is especially useful for one-time or occasional secure communications and still supports compliance by protecting the message with a strong password.

Think of this like setting up a new account with your favorite online service—recipients get to create their own username and password, making it easy for them to access their secure emails from Cloudstar whenever they need. This method empowers users with self-service access, while giving IT teams full visibility and the flexibility to enable extra security features, like sending a one-time passcode to the recipient when they register. It’s a convenient way for your organization to offer secure email without needing to hand out credentials or do a lot of manual setup, and it’s great for maintaining compliance and audit trails.

How does sandboxing protect against unknown threats?

Sandboxing safely opens and observes suspicious email attachments in a secure, isolated environment. This allows harmful behavior to be detected without exposing your systems to risk. If malicious activity is found, the attachment is blocked before it reaches the user.

Why is real-time scanning important for email security?

Real-time scanning checks emails, links, and attachments the moment they are accessed or clicked. This ensures protection against the latest threats, even those that were created after the email was delivered, and helps prevent zero-hour attacks from slipping through.
