Decide what deserves trust before anyone acts on it.
SIP Shield is an email trust-control layer for people and teams who are tired of spoofed banks, fake invoices, phishing links, impersonation, and suspicious sender behavior. Instead of silently filtering in the background, SIP Shield holds uncertain mail, explains why it looks risky, and gives the right person a safer review path before trust is given. Now with anti-spam scanning at no extra cost for active users.

The real risk is not obvious spam. The real risk is early trust.
A sender may appear familiar. A PDF may look safe. A payment request may feel urgent. Users do not usually make a mistake because they are careless. They make a mistake because the email looks legitimate for just long enough to earn trust.
SIP Shield creates a safer review point before a message is treated as safe. That means the important moment is protected: the moment when someone is about to preview, open, respond, or take action.
It does not try to promise that all email noise disappears. It focuses on a more practical goal: help the right person pause, inspect, and decide more carefully before trust is given.
Clearer review. Better timing. Safer decisions.
SIP Shield is designed for practical trust control across everyday email workflows, not vague background filtering that users cannot understand.
Explain the risk
SIP Shield shows why a message looks unsafe, suspicious, spoofed, or uncertain instead of acting like a black box.
Hold uncertainty early
Messages that deserve a second look can be held outside the normal trusted path before someone acts too quickly.
Review with control
The safer review path helps the right person decide what deserves trust before a risky message becomes routine.
Per mailbox simplicity
One customer login can manage several protected email accounts while pricing stays easy to understand.
Cross-device outcome
Once handled at the mailbox level, the safer result carries through to the devices people already use.
Practical rollout paths
Deploy SIP Shield on desktop, server, or WebScan and keep one core review idea across all environments.
Use the same trust-control idea in the environment that fits you best.
SIP Shield works for individuals, teams, and businesses that need protection on a workstation, on the server, or through a mobile-friendly browser flow.
macOS / Windows
Best when your mailbox-cleaning agent should run directly from a desktop or laptop.
Server Deployment
Best when trust control belongs inside a company-managed mail environment or internal infrastructure.
WebScan
Use SIP Shield through the website with no desktop app required. Ideal for mobile users and browser-first review.
Protect the decision point in four practical steps.
SIP Shield is built around a safer sequence: uncertainty is identified, the message is held, the reason is shown, and trust is granted only after review.
Message arrives
A message appears relevant, routine, urgent, or familiar enough to seem worth opening.
Uncertainty is held
SIP Shield keeps uncertain mail outside the normal trusted path before quick action happens.
Risk is explained
The user or reviewer sees why the message looks suspicious, spoofed, or unusual.
Trust is decided safely
The right person reviews more carefully before opening, replying, previewing, or acting.
Easy to start. Easy to understand.
One customer login can manage multiple protected mailboxes. Choose monthly, quarterly, or annual billing based on how you want to roll out protection.

Not just detection. Controlled trust.
Many tools promise to detect bad email. SIP Shield is different because it is built around the practical moment when somebody is about to trust a message.
That makes it easier to explain internally, easier to roll out across devices, and easier for people to understand what they are being protected from.
Quick answers before you get started.
Keep expectations clear: SIP Shield is designed to protect trust decisions, not to market itself as a traditional spam blocker.
Does SIP Shield stop spam?
SIP Shield now includes a baseline spam-protection extension at no extra cost. It remains focused on protecting the trust-decision moment before risky email is acted on.
Can one login manage several mailboxes?
Yes. One customer login can manage multiple protected mailboxes while pricing still remains per mailbox.
Can I use it on mobile?
Yes. Choose the WebScan / web-mobile path if you want to use SIP Shield through the website without a desktop app.
What if I need a business rollout?
SIP Shield supports both desktop and server deployment paths, making it suitable for individuals, teams, and larger environments.
Is Gmail supported?
Yes, through Google OAuth. Gmail is not supported through direct IMAP password login.
What mailboxes work best with hosted WebScan?
Standard IMAP mailbox providers that allow direct third-party IMAP access are the best fit for the hosted path.
